DIPSO incorporates the dynamic mutation, multi-subpopulations methods of IPSO, and changes the heights and the positions of the peaks by variable parameters and chaotic model. This algorithm uses multi-subpopulations to search for the highest peak in order to track the dynamic environments. Furthermore, DIPSO apperceives the changes of the environment by tracking the fitness value of the global optimal particle.

According to the shortage of only considering the phase change of emitter and no refer to the amplitude change, based on the patterns of radar and decoy, using equal phase gradient method, while considering the influence about waviness of phase and amplitude of each, the decoying formula of the coherent decoy system is deduced, a damage probability model is drawn out.

针对目前多点源诱偏效果评估过程中，仅考虑各点源相位分量变化，未考虑幅度分量在空中变化的不足，基于雷达和诱饵的具体方向图，运用等相位面梯度分析法，同时考虑各点源辐射信号的相位和幅度波动的影响，对相参多诱饵系统的诱偏误差公式进行了推导。

Frictional experiments using a self-designed "multifunction servo friction and abrasion experiment machine" with the multi-parameter synchronous data collection system and online data processing software have been made on six types of rocks. The analyses of the experiments results indicate that earthquake faults with large displacement bring up a series of products continually changing from cataclasis to melting. The rocks contained mafic minerals are easier to melt and the gas bubbles in melting products proved the hydroxy water from the minerals has participated the rock melting process and decreased the melting point of the rock. Frictional melting is more sensitive to speed than normal stress. The temperature sharply increases at about 40℃/sec when the sample enters the earthquake fault state. While the melting happens, torsion decreases instantly and there is perhaps a "blind region" of normal stress.

利用自行设计加工的&多功能伺服摩擦磨损实验机&，及多参数同步数据采集系统和联机数据处理软件，对六类岩石进行的实验和分析成果表明：大位移地震断层作用形成了与滑动速率有关的从碎裂到熔融连续变化的系列产物；含镁铁质矿物的岩石更容易熔融，熔融产物中出现的气泡证实了矿物羟基水很可能参与了岩石的熔融过程并降低岩石熔点；相对于正应力而言摩擦熔融程度对速度变化更加敏感；此外，进入地震断层状态时温度急剧上升达～40℃/秒；伴随熔融发生出现扭矩骤减时，可能存在一个短暂的正应力&盲区&。

"Nothing that has come out in the public as a result of the recent e-mail hackings has cast doubt on the basic scientific message on climate change, and that message is quite clear - that climate change is happening much, much faster than we realize and we human beings are the primary cause," he said.

潘基文说：&最近电子邮件被盗一事并没有影响公众舆论，或者给气候变化的最基本科学信息带来质疑。那一科学信息是很明确的，就是气候变化的速度比我们所认识的要快得多，而我们人类是导致气候变化的主要原因。&

Based on the study of chronology and geochemistry of Cd in sediments of the Dongting lake area, we have established an ARIMA model of Cd and Cd/Ca in Quaternary and Holocene period respectively, and discussed Cd evolutionary regularity according to the fitted value and predicted value of the model The results revealed that the Cd evolution has remarkable periodicity of ecogeochemistry cycles, and is correlated with the climate change of alternative cold and warm Cd/Ca is changed with climate, from which the evolutionary history of regional ecogeochemistry can be inferred The changes of Cd and Cd/Ca are basically simultaneous, which showed that the change of Cd is mainly a natural evolution Cd in sediments will rise in the next 30 years and then tend to decrease From the regularity of ecogeochemistry indexes and global environment variation, it is concluded that the natural environment is the dominant factor affecting the Cd deposition
