Based on the characteristics of short-duration and abrupt of blasting vibration signals and according to measured data from a practical blast,the features of energy distribution in blasting seismic signals were studied by means of the wavelet packet analysis,which had high resolvability and localization,and energy distribution of blasting seismic signals on different frequency bands was obtained.

根据爆破地震信号具有持时短、变化快等特点，结合工程爆破地震监测资料，利用小波包良好的时频局部化性质，对爆破地震信号的能量分布特征进行了分析，得到了爆破地震信号不同频带上的能量分布。

The aim was to analyze the function of gene by bioinformatics method. The physical and chemical characteristics, structure and function of Na(superscript +)/H(superscript +) antiporter gene TaNHX1 on the tonoplast membrane in wheat were predicted through analysis by the software from bioinformatics data base and internet.

They are decidable in polynomial time.

5另外，我们还发现，对任何前向链正规的逻辑程序P，总存在一个最小的P上的一致性性质使得P是关于它前向链正规。

Various physical and chemical reactions of oil and gas were inevitably occurred with the contacting rock on the process of migration. The physical and chemical characters of the petroleum and the reservoir were induced to change disciplinarily. So the rules were used to research the direction and the route of petroleum migration.

油气在地下运移过程中，将不可避免的与围岩发生各种物理化学反应，导致沿运移的方向上油气物理化学性质和储层某些性质规律性的变化，因此研究中可以利用这些变化对油气运移方向与路径进行分析。
