In the prospecting of faults by the refraction method, not only the ordinary refracted waves from the downthrow and upthrow sides of a fault and the diffracted waves from the fault plane are observed but also certain secondary waves resulted from diffraction and transmission can be recorded on the seismograms. The whole set of waves constitutes a very complicated picture of the seismograms. If their kinematic and dynamic characteristics are not capable of being recognized and distinguished, it would be very...

In the prospecting of faults by the refraction method, not only the ordinary refracted waves from the downthrow and upthrow sides of a fault and the diffracted waves from the fault plane are observed but also certain secondary waves resulted from diffraction and transmission can be recorded on the seismograms. The whole set of waves constitutes a very complicated picture of the seismograms. If their kinematic and dynamic characteristics are not capable of being recognized and distinguished, it would be very hard to interpret the results of fault prospecting by the refraction method. In most of the previous literatures, only the diffraction phenomena on the edge of a plate have been discussed while the secondary waves by diffraction and refraction appearing possibly on seismographie records when both the upthrow and downthrow sides of the fault are present have been neglected.In this paper, the results of a model experiment using ultrasonic impulses are described and studies made in connection with the prospecting of faults by the refraction method of different throw magnitudes, the recorded anomalous refracted waves and secondary waves.

用折射波法对断层进行勘探的实际工作中,不仅观察到上、下盘的正常折射波及棱上的绕射波,而且还可以看到因绕射、透过所产生的一些次生异常波.这些波郁同时在记录上出现,并构成一幅复杂的波形图.如果不能一一地识别它们,并掌握它们的运动学及动力学特征,就无法正确地识别及解释断层.以往一些文章多半讨论板状介质边缘上的绕射现象,而未涉及上、下盘同时存在时,折射法记录上可能出现的次生绕射、折射波. 本文为了解决这一问题,利用了超声波脉冲地震模拟仪进行了实验,对不同大小断距情况下的折射异常波及次生波进行了研究,回答了有关断层勘探中必须阐明的一些问题.

A method to abstract vibration signals in this paper is presented for the first time. Different forms of frequency, amplitude and phase can be identified among vibration waves of various forms by this method.Modal shapes of vibration can be obtained when this method is applied in a mechanical structur together with multi-metering. This paper also provides an analogous result of a computer as a practical example.

The results of this program, and the analysis on them show that the Seasonal popalation fluctuation carves of the Commensal rodents in the city and the countryside are similar basically inwave shape, which suggests that in the two ecological conditions, that of the city and that of the countryside, do not produce markedly different influences on the seasonal population fluctuation of the commensal rodent, Of the three leading species(Rattus norvegicus, Mus musculus and Rattus flavipectas) although there are some differences or even some characteristic between their seasonal population fluctuations, they are not enough to become the reliable marks to distinguish them from each other because of being affected So much by. outside environment factors. Also the analysis based on the Norway rats and the house mice shows that the natural ecological Condition of the faunae (Zoogeographical divisions)is not the factor which have a great or important influence upon the sensonal population fluctuati of domestic rodents, in other words, there is no notable relationship between the two.

监测结果及其分析表明,城乡家鼠季节性数量变动曲线的波形基本相似,即城乡两种生态环境对家鼠的季节性数量变动无明显影响;三种家鼠(褐家鼠、小家鼠、黄胸鼠)的季节性数量变动曲线虽有一些差异甚至特点,但受外界环境因素影响很大,不足以成为互相区别的可靠标志;通过对褐家鼠和小家鼠的分析还表明,以动物地理区划为代表的自然生态条件不是影响家鼠季节性数量变动的主要或重要因素,二者之间无明显关系存在。本文采用的“同步起伏分析法”,对于具有复杂波形的鼠类季节性数量变动曲线的相似性分析,可获得明确的结果。
