  1. On the basis of the calculating of complexity ( c value ) and combination entropy ( h value ) from the numerical method of geoanomaly analysis, logged signals data ( spontaneous potential, acoustic slowness, spontaneous gamma ray and electrical resistivity ) and seismic data ( amplitude, frequency, phase, etc. ) are processed after regularization of data obtained from linqing basin of shengli oil field. many types of geoanomalies obtained from the computation are analyzed so the spacial variation rules of them can be discovered. then the oil regions can be predicted by this method

  2. These researches provide us a basis for forecasting the pests in grain in earlier stage, accurately utilizing pesticides, improving the efficiency of prevention and reducing the loss of stored grain. the sound absorption properties of various types and thickness of grain are measured by means of the standing wave tube technique. the following conclusions can be drawn : for the same thickness the larger grains has a smaller sound absorption coefficient than the smaller grains

    為了有地研究儲糧害蟲所產生信號在各種糧食中的傳播特性,本文採用駐波管法,對十一種不同種類糧食在不同堆積厚度情況下的性能進行了實驗研究,糧食特性與其顆粒的大小、形狀、排列方式及糧食堆積厚度有關,存在一定的規律,得出如下結論:同一厚度下,顆粒大的糧食較顆粒小的性能差,顆粒由大到小,峰值頻率向低頻方向移動;球形顆粒糧食較長形顆粒性能差。
