ABSTRACT: The reflection coefficient for spherical waves at a given
eaz,d 1/2
angle of incidence equals the reflection coefficient for
plane waves and depends on the values of velocity and density
on both sides of the boundary and the angle of incidence.
For angles of incid.ence which are less than the critical
angle ilcr (where ile, = are sin alls.2; al and a2 -
speeds of longitudinal waves on either side of the boundary)
the reflection coefficient for longitudinal plane waves
changes uniformly vrith increasing angle of incidence. The
present paper deals with experimental reBUltS obtained for
waves reflected at angles of incidence larger than the
critical angle. Two cases were employed; a2/al - 2.5 and
a2/'1 0 1.8. It J.s shown that in certain media reflected
waves can be detected at distances corresponding to angles
of incidence equal to or greater than the critical angle

which are greater than those of the refracted waves. A
rapid change in the reflection coefficient as a function of
the angle of incidence may lead to a rapid change in the
amplitude and form of the reflected wave with changes of
distance from the point of explosion. At some distances a
rapid increase in the amplitude of reflected waves may occur
which may give the impression that new waves are being formed.
Further experimentaL theoretical studies of the relations
between intensities of refracted and reflected waves in
different media are necessary,

ABSTRACT: An experimental division of waves into two classes,
multi- and singly reflected, was attempted in a region
where intensive multi- reflected waves could be easily
,obtained. The multi- reflected waves were further divi-
ded into fully and parzly reflected waves. It was found
that the majority of waves were reflected several times
from one discontimtity layer, H -^_ 800 m deep, the charac-
teri8tic coefficient of reflection of which was large
(q - 0-3). Also it; was established that the waves fully
reflected from the discontinuity at H - 800 m were again
reflected from a strata characterized by a low velocity
coefficient. The method of the vertical hodograph (Pig 1)

The Determination of Different Types of the Multi- Reflected Waves
According to Their Kinematic and Dynamic Characteristics
was applied to determine the possible waves of multi-
reflected wave propagation. It was found that the kinetic
characteristics of waves were often inadequate for deter-
-mining the wave paths. Therefore, another method, based
cn the amplitude's ratio of multi- and singly-reflected
waves was applied (Eqa (2)-(4)). The number of multi-
reflected waves recorded simultaneously by two seismographs
of different frequencies (Sch - 37 h 9 Vck - 105 h) were not
equal. This could be explained by both the different ab-
sorbing properties of strata and by the different absorption
of waves of different frequencies. It was also found that
the number of singly-reflected waves recorded by the high
frequency apparatus was much greater than that recorded by
the low frequency one. The experimental data are given in
the form of graphst Figs 1-12. They illustrate the follow-

1959, Nr 8. pp 1089-1102 (USSR)
ABSTRACT: The work is based on the type of multiple reflections
(Fig 1) described by Bortfeld (Ref 1) and observed by
the author in his research in various localities, such
as the Ukraine, where the effective velocity of multiply
reflected waves was found, as illustrated in Fig 2
(1 - seismic sounding, 2 - mean curve V eff = f(t).
3 - actual data of effective velocity). The waves'
characteristics were investigated in three types of
stratifications as shown in Fig 3, where a - medium
with thin strata, b - stratified medium with density
increasing with depth (constant velocity), B - as b but
velocity increasing with depth. The number of reflected
waves recorded during the time T (T = nt ) depends on
the character of stratification as shown In Fig 4.
The minimum nYKI er of waves N reflected k times in
n strata (N can be calculated from Eqs (1) and
Card 1/3 sults n.
The re 0 such calculations are given in Table 1.

Eqs (3) to (8) and Table 2 are applied to the first type

.The relationship bostween the ampli e of a resultant
wave and that of a single wave, A /A single' is
illustrated in Fig 5, where the continuous lines are given
for the first type and the dashed lines - second type of
stratification. The relationship between A P, /A singl~e
and n for the first two (curves I and 2) types of
stratification is t3hown in Fig 6. Fig 7 gives the
function A /A `~ f(n) for the stratifications 2 and

3 in the same scale as in Fig 6. It should be noted that
the resultant amplitude in a medium with a greater number
of stratifications can be larger than that of a single
wave, In the case of a medium with thin strata and a
constant coefficient of velocity, the resultant multi-
Ca,d 2/3 reflected waves become more intense than the single waves.

TEXT: The possibility was shown for the use of the 80 - 120 c/s
frequency band for recording waves refracted from boundaries occur-
ring at a depth of a proximately 500 m. Observations with a high-
frequency apparatus N BLJC.C-22 (VChSS-22) station) were conducted
jointly with observations from a standard middle-frequency appara-
tus (CC-26-51-A (SS-26-51-D)',' and 19XOI-l (EKhO-1) stations). It
follows from a comparison of seismograms that the recording of the
HF-stations is rarefied better than the recording of the MF-station
Thanks to thist a greater number of waves is distinguished on the
HF-seismogramep the wave changes are reflected more clearly, and

Experimental use of high-frequency D228/D304
the extent of the interference zone is substantially reduced. In
most cases the reception range of vibrations with the use of the HP-
apparatus equalled 3.5 - 4 km; when the MF-equipment was used the
reception range amounted to '18 - 20 km. The use of a high-frequency
station is more difficult and economically less effective than is
the case with middle-frequency stations; this is governed by the
need, when working with HF-equipment, to increase the degree of de-
tail of the profile network and observational systems and to select
more carefully the stimulation conditions of the vibrations, It is
concluded that, when studying the Palaemoic basement in Western Si-
beriat middle-frequency stations should be used as the main equip,
ment. Observations with high-frequency apparatus may be expediently
carried out in separate areas where a high degree of detail 16 np-

TLXT: The conditiorsof the formation of multiple reflected waves
are considered, and their classification is given. The question of
the frequency selection of multiple waves is analyZed in detail.
As a rule, in connection with the great environmental absorption
ofhigh frequencies, the spectrum of multiple'waves has a lower
frequency than that of asingle wave. Therefore, the use of high-
frequency filtrations in which.the friequency characteristic has a V~
steep left-hand cut often giveo good results. In a number of cases
when reflection-occurs from a thin bed multiple waves are of higher

ABSTRACT: The reflecti 'on coefficients of plane waves in the region'of the second
critical angle cre analyzed from the point of view of geometric ray theory. The
reflection coefficients of plane waves substantially depend on the parameters of
the media. Thin dependence was investigated and it was ahown that the position

ABSTRACT: A seminar on problems related to multiDle reflectedyqves :In seismic

Ahe USSR Ministry of Geology, the. All-Union Scientific Research Institute
of Geo hvsical Prosvecting LA~tthg4s. (VNIIGeofizika), tIje_lnf~tjtUtC__ok_11jjp
Physics of the Earth (IFZ AN SSSR), and the State Committee of the USSR
Council of Ministers for Science and Technology. Major,topics discussed.
were the status of work being carried out by the reflected-wave 'method In
various areas of the USSR, and new Improvements In field procedures and
in apparatus for distinguishing and damping multiple waves.
A number of the papers presented evidence that intense multiple -waves
had been identified on seismagraTs,qbtained when using the MOV method
.(Western Siberia, Volga area, UK~Mne, Kazakhstan, Krasnodarskly Kray,

'Acd -NOI -'--
n'
Timan-Pechora Province, Azerbaydzha , and other regions). Waves of
this type, generally related to the presence of a water layer, had also been
registered while seismic prospecting was being carried out In the Caspian
and Black Seas.
Another portion of the session was devoted to discussion of the results
of studies of the kinematic and dynarnic characteristics of multiple waves
and their comparisons with such single-wave characteristics as effective
velocities, relative intensities, and wave-frequency spectra; they were
carried out at the IFZ, the Lower Volga Institute of Geology anid Geophysics
(NVNIIGG), the Siberian Scientific Research Institute of Mineral Resources
(SNIIGIM ), the Leningrad Division of the Institute of Mathematics (LOMI).
and elsewhere. Results were also presented of studies of the special
features of the velocity profiles of real media in which intense multiple
waves occur (performed by the IFZ, NVNIIGG, VNIlGeofizika, Perm
State University, and other Institutionp).
Papers by A. M. Yepinatlyeva,of the IFZ and Yu. B. Zinizer of the
NVNIIGG dealt with the great dependence of the dynamic characteristics of
multiple waves on the character of amajor (sharp) discontinuity in a section
and the variability of these characteristics with the area. Representatives

Trus-t presented'pa 'ers dealink'with the re'gfonallzation of an area In accord-
p
,ance with multiple-wave peculiarities and the determination of optimum
,conditions for registering single waves against a background of multiple
.waves. The latter was achieved either by the experimental selection of
conditions for wave registration or on the basis of theoretically calculated
:intensities of the single and multiple waves for known profiles. The work of
,the Volgograd expedition of the NVNJIGG, in which multilayered and thin
jayered real media were considered, was commended as being especially
inoteworthy.
Diptinguishing Mult4ple Waves
At present, the methods most widely used to' Identify multiple waves
are based on analyses of effective -velocity data. Papers by N. Ya. Kunin of
,the Kazakhstan Geophysical Trust at~d by ']C_, L, Koprq4 of the Yakutsk
Geological Administration described how statistical analytical m-_e_t_1_iod-s had
yielded more reliable. and accurate results. A. K, Urupo and others
(Perm UnlypEsity) developed and tested a parametric diagram technique
for distinguishing multiple waves. Examples of areas where reliable wave
identifications have been accomplished from kinematic criteria Include the
9-nrA '3/10,.-

Russian and Siberian platforms, the Caspian and Black Seas, and other
,regions In the USSR.
The, seminar pointed out the major possibility for distinguishing multiple
waves detected by vertical seismic profiling methods and synthetic seismo-
grams,
The vertical profiling method'developed by Ye. -1. Gal'Reri at the IFZ
makes it possible to determine the nature of waves, in particular to identify
single and multiple waves and to prepare simplified physical models of real
media. The appropriate apparatus has now been built and put into mass
.production. A number of field organizations have used this simplified
iveriical seismic-profiling method and have obtained satisfactory results
(Eastern Geophysical Trust, Ukrainian Geophysical Trust).

.Sugprgssion of Multlpl*e Waves
The following methods of suppressing or damping multiple reflected
waves and the detection, of useful waves against a background of multiple
waves were discussed at the seminar:
1. Frequency selection methods. Experimental and theoretical methods
used at the IFZ to test the frequency selection method for damping multiple
waves showed that In certain types of media It Is possible to damp or re-
duce multiple reflections by a technique which is based on the different
frequency spectra of single and multiple waves. In field testing the method
In some regions vVhere multiple waves are formed at the contacts of thick
~aycrs, good results were obtained with high-frequency filtration (N. V.
VMperovich,, western Siberia). In regions where thelormation of multiple
waves in non,ociated with thin layerg, there are Dome examples where the
uhe of low-frequency. filtration has been successful (B. M. Karasik In
some areas Qf ICras.nodars)dy Kray). 'In most areas, however, frequency
selection has been Ineffective.

ACC.. RT__AP6_Wi41O
2. Directional -mode and wave -gene ration methods (plane front used by
1. 1. Kharaz and others, grouped shots on long bases, directed and un-
directed modifications used by B.' 1. 'Bespyatov and V. G. Yurchenko,
varioua polar groupings used by Yu. V. Lorens1dy). These methods are
;based on differences in apparent velocities and the degree of stability,
depending on tW3 area, of single and multiple waves. The largest amount
of research using these methods has been performed by the NVNIIGG and the
Ukrainian Scientific Research Mining Institute (KkrNIGR1).
3. Various methods of signal. separation. Filters have been devised
whose characteristics are Identical in form and opposite In sign to the
frequency characteristics of the uppor layers in which most. Multiple waves
are formed (Division of Marine Geophysical Work 0 GIR) o-fthLe
YNL
Geofizi!A, L,_I, Kogan, L K. Kondratlyev and others). Obviously, these
will give the best results in seas and oceans. A method is being developed
'for the successive separation of signals using an electronic computer and
an analog device; which does not require prior knowledge of the section
and useful signals (S. A. 'Nakhamkin of Leningrad State UniVersit ). Noises
Y
(multiple waves) with known apparent velocities are being separated out
'from seismographic observations. These methods for damping multiple
waves have stM not been tested experimentally.

4. Use of electronic computers In solving inverse dynamic probloms.
Work of this sort has just begun at the IFZ, LOU, VNIlGeofizika, and the
'Institute of Geophysics of the Ukrainian Academy of Sciences. The dis-
tinguishing feature of this method is that multiple and single waves need
t not nocessarny be different in character, and multiple waves should also
be taken from the~recording.
New methodi- of' suppressing multiple waves now being developed and
bused outside the'8oviet Union. The basicIdea is multiple overlapping, or
.,.common points and radiational filtration, accomplished by using special
vapparatus with rn~aignetic registration. The principle features of these
.methods are: summing of a large number of traces, carrying out observa-
tions far from the source, and the e;3tablishment of special c6nditions favorin&
for the most part, the magnification of single , waves. These methods involve
the use of several criteria, which differfor multiple and single waves in
direction of arrival, spectral composition, and degree of wave stability
by area. The use of not one, but several criteria, even when they are weak,
-obviousV makes it possible to achieve significant damping of multiple waves.

A communication from 1. M. nXabchenko of the Saratov Special
gn Bureau (SKB) indii-,ated that he has. completed -work on an apparatus

AC6-N*Rt
which makes'possible observations by the multiple -overlap method. Certain
theoretical problems In tfils method were discussed In a paper by Yj, ___ ,
-M=I&Qy (I'Krasnodarneftogeoflzlka" Trust). In a paper by the IFZ, AN
SSSR, a positive example was presented of the combined use of frequency
selection and ounimation of waves on long bases (with time delays) for the
suppression of multiple waves.
The resolutions of the seminar pointed out that, even though research
onmultiple waves has been greatly expanded during the last few years,
results obtained are still unsatisfactory, with the following problems still
needing attention:
1. Inadequate instrumentation (Inadequate supply and slow production of new
Instruments: individual experimental instruments developed by one organiza-
tfon and even after considerable time still unavailable for use by otherorgani-.
zations -including, for example, vertical -profiling apparatus, ultrasonic
borehole logging equipment, apparatus used for signal separation, etc,).
.2. Scie~ntific research Is too limited In scope and variety of approaches.
information concerning new apparatus, procedures, and theoretical devel-
opments at vario us USSR or gan izations is poorly organized.

The Z-alkylcyclopentanonos necessary for the reaction were obtained by alkylation of
cyclopentanone with aldehydes (proplonic, butyric and enaaffile). Ilia properties and
:':names of the synthesized hydrocarbons are tabulated. The Grignard reaction was

With unsaturated ketones, the yield of tertiary alcohols was muchbigher. 7lic chromatogram
of 1-mothyl-2-cyclopentyleyelopentane, obtained by tho reaction of methyl-magneslum
Iodide with both unsaturated and saturated ketones, Is given. In both cases, the identical
mixture of trans and cis-l-mothyl-2-cyclopentylcyclopenLancs were obtained. Initial
