Where difficulty has been encountered in obtaining good reflections, it has become almost a general practice to use a group of seismometers insteads of a single seismometer in a channel. One of the primary advantages in such a method is to increase the ratio of useful to extraneous energy recorded in seismogram. If the seismometers are too near to each other, benefit is seldom obtained, because all seismometers in a channel might be considered to be placed at a single point and multiple detection is only a method of increasing the amplitude both of useful and of extraneous energy. As the separation of seismometers becomes large enough, microseism can be assumed as a random noise, the signal to noise ratio will be increased n~(1/2) times by using multiple detection, when the effective waves strike the seismometers fairly well in phase. But where reflected waves from strong dipping or shallow beds are involved, the discriminatory powers of seismometers might defeat its purpose unless the seismometers in each group are closely spaced. Assuming microseisms to be plane waves traveling to the earth surface from random directions, the problem of how far the detection can be improved when the seismometers in a single group are closely spaced is studied in detail. It is shown that the relative amplitude of microseisms in the records depends statistically not only on the numeber of seismometers in a single group, but also on distances between them, the microseismic frequency spectra and the elastic velocity in the medium. The result obtained in this paper can be used as a guide for choosing multiple seismometer confiquration in seismic field operation.

地震勘探組合法中,采用很小的組內检波器間距离吋,組合法仅只起提高接收仪器灵敏度的作用;检波器間距較大情况下,微震干扰可以看作相互独立的随机干扰来研究;但在間距不太大但也不能认为等于零时,組合方法的效果却是个尚待討論的問題。本文假定微震是由传播方向随机改变的平面波形成的,用概率論方法討論了組合地震法对徽震干扰的压制效果。

The process of the yield formation of rapeseed(B.napus)wasanalysed on the basis of a series of studies.of the three yieldcomponents of rapeseed,that which has most influence on the seedyield is the number of siliques per unit area(it was estimatedthāt 10,000 siliques could give approximately 0.5kg.of seeds),whereas the number of seeds per silique and the 1000-seed weightwere of comparatively less importance.Therefore,in order to in-crease the seed yield it was necessary to increase the number ofsiliques per unit area.The way to increase the number of siliques per unit area is toincrease the number of plants per unit area and the number of siliquesper plant.It was indicated by the path coefficient analysis that if theplanting density of the rapeseed crop was within the limit of 20,000plants/mu,the seed yield increased with the increasing of plantingdensity.This was particularly true within the limit of 10,000 plants/mu.(The optimum density of the rapeseed crop in the Yangtze Valley isabout 10,000-15,000 plants/mu)The way to increase the number of siliques per plant is to increasethe number of siliques of the primary branch,i.e.to increase the totalnumber on the main stem,to increase the ratio of formative branches,and to increase the number of available buds before the budding stage.The way to increase the number of seeds per silique is to increasethe number of ovules per silique and the percentage of fertilized ovulesso that more zygotes could develop into seeds.Since the seedling stage(before the budding stage)of rapeseed isa very important period not only for the vegetative growth but alsofor the differentiation of effective buds,it was suggested that special care should be paid to the management of this crop before and during wintertime(when the crop had been planted with an optimum sowing dateand density).However,the management of the later stages shouldn'tbe relaxed if a higher yield is to be obtained.

The tetraribonucleoside triphosphates ApUpUpC(10), CpGpGpA (25) and the tetranucleotide ApUpUpCp(30)corresponding to 58~61 and 62~65 fragments of the yeast alanine transfer ribonucleic acid molecule together with another tetraribonucleo-side triphosphate ApUpCpU (16) have been synthesized.As shown in Fig. 1, 2, 3, and 4, protected tetranucleoside triphosphates and tetranucleotide were obtained by condensation of the appropriately protected dinucleo-tide with protected dinucleosido monophosphates or protected dinucleotides. The protected dinucleotides and dinucleoside monophosphates were prepared by coupling the appropriate protected nucleotide with protected nucleotide and nucleoside respectively.The protecting groups were so chosen that the acid labile p-monomethoxytrityl (MeOTr) group was used for 5'-hydroxyl group of the ribose moiety, the alkali labile acyl groups (e.g. acetyl, isobutyryl and benzoyl group) for the heterocyclie amino group and 2'-hydroxyl group of ribose-moiety, and the aniline group for the 3'-terminal phosphate group. The protected nucleotides prepared according to the preceding reports were employed as starting materials in this work. For guanosine 3'-phosphate, several acyl groups had been tested. 2'-O-Acetyl and-isobutyryl groups were found to be too labile. However, the stability of 2'-O-acyl group can be increased if the 2'-hydroxyl and heterocyclic amino group are blocked by different acyl groups, e.g. acetyl for the heterocyclic amino group and isobutyryl for the 2'-hydroxyl group. Thus a relative stable N-acetyl-2'-O-isobutyryl-5'-O-methoxytrityl guanosine 3'-phosphate was prepared from guanidylic acid by acetylation followed by partial saponification, monomethoxytritylation and acylation with N-isobutyrylimidazole.In order to compare the stability of the acyl groups generally employed in the oligonucleotide synthesis under the present experimental conditions, each of six guanosine 3'-phosphate derivatives blocked with different acyl groups were dissolved in two separate buffers, i.e. 0.5M solution of triethylammonium acetate in 70% ethanol (pH 6.8) and in 50% aqueous pyridine(pH 8.5) respectively. The six derivatives were N-acetyl-, N-isobutyryl-, N,2'-O-diacetyl-, N-acetyl-2'-O-isobutyryl,N-acetyl-2'-O-benzoyl, and N, 2'-O-diisobutyryl-guanosine 3'-phosphates. An aliquot was taken out for paper chromatography at intervals, and the chromatograms were examined under UV light. It is shown that N, 2'-O-diacetyl and N,2'-O-diisobutyryl-guanosine 3'-phosphates are unstable. In case of N, 2'-O-diacylguanosine 3'-phos-phates, the stability of 2'-O-acyl groups was in the order of benzoyl>isobutyryl>acetyl(Fig. 16, 17). In agreement with our findings, recently Ohtsuka et al. also reported that due to the instability of 2'-O-isobutyryl group of N, 2'-O-diisobutyryl-guanosine 3'-phosphate, benzoyl group was preferably used for the protection of the 2'-hydroxyl group.Dicyclohexylcarbodiimide was mostly used as condensing reagent in our work. The yields of dinucleotide monophosphates and tetranucleoside triphosphates were in general about 40% and 30% respectively but affected by various factors. In case of 22, the yield was increased by ca. 8% on increasing the ratio of the nucleoside component to the nucleotide component from 1:1 to 2.5:1. When N-mesitylenesulfonyl-tetrazole was used as condensing reagent, a 5% increase in the yield was obtained. However, no significant change in the yield of the protected GpA was shown when trityl and benzoyl groups were used in place for the protection of 5'-hydroxyl group and 2'-hydroxyl group of guanosine 3'-phosphate respectively. On comparison of the yields of the dinucleoside monophosphate (ca. 40%) with those of the dinucleotides (ca. 30%) and the yields of the tetranucleoside triphosphate (30%) with that of tetranu-cleotide (29) (12%), it is clear that the presence of a terminal phosphate group may lower theyield of the oligonuoleotide and the difficulty in linking 3'-guanidylie acid to guanosine by the present chemical method causes the poor yield of protected CpGpGpA(10%).In the present paper, the general procedure of the preparation of oligonucleotides was adopted. The nucleotide and nucleoside components were employed in molecular ratio 1:1.2 in general, and dicyclohexylcarbodfimide was used with 10 folds excess based on nucleotide component. The crude product obtained was chromatographed on DEAE-celluloso (acetate) column (Fig. 5, 6, 8). The purified product was deblockod, then rechromatographed in DEAE-cellulose (bicarbonate) (Fig. 7, 9) or RPC-5 column or by paper electrophoresis. The oligonucleotides thus obtained were of purity greater than 90%. The base ratio of thus purified products wore determined through enzymic hydrolysis (with pancreatic RNase, RNase T_1, or spleen phosphodiesterase) or alkaline hydrolysis. The purity and sequence of ApUpUpC and CpGpGpA employed in the syntheses of dodecaribonucleoside, undecaphosphate and hexadecaribonucleotide pentadecaphosphate were further checked by two dimensional electrophoresis and homochromatography after labeling 5'-terminal OH group with ~(32)p(Fig. 10, 11), and by sequence analysis after partial hydrolysis of the 5'-~(32)p labelled tetraribonucleotide with snake venom phosphodiesterase(Fig. 12, 13).
