Then we transfected transitorily the recombinant of green fluorescent protein gene and middle molecular weight neurofilament cDNA into wide type N2a (N2a/wt) and N2a/tau40 to observe the effect of tau accumulation on GFP-NFM fusion protein transport in cellular processes in living cells. At last we used an apoptotic inducer, camptothecin (an inhibitor of topoisomerase-1) to treat N2a/wt and N2a/tau40 cell lines, and compared their apoptotic response.

The Markov forecast model, time series method (triple exponential smoothing method and a combined of triple exponential smoothing method and Markov model) and stepwise regression forecast method were choosed, and the basic principles and processes of the three models were analyzed and compared. Based on above, the three methods were used to predict population dynamic of Cricetulus barabansis and Meriones unguiculatus. The characteristic, accuracy and applicability of three methods were analysed and compared. The results showed that,(1) Markov model belongs to a middle-long time forecast model, and the result was interval forecast, but it reached the requirement of forecasting the harmful population dynamic of rodents. Through the forecasted population dynamic of Cricetulus barabansis and Meriones unguiculatus in 2004, the results were accurate; this meant that Markov model was a good forecast model to Cricetulus barabansis and Meriones unguiculatus population.

选择马尔可夫链预测模型、时间序列分析法(三次指数平滑法、三次指数平滑法和马尔可夫链预测模型的组合预测法)和逐步回归预测法，对这三种模型的基本原理、模型的构建过程进行对比分析，在此基础上用此三种方法预测了黑线仓鼠和长爪沙鼠的种群数量，并对三种方法的特点、预测的准确度和适用范围进行了比较分析，结果表明：(1)马尔可夫链预测模型属于中长期预测，预测的结果为区间预测，但对于害鼠种群数量的预测来说已经达到要求，通过对2004年黑线仓鼠和长爪沙鼠种群数量的预测，预测的结果都比较准确，这说明对于预测黑线仓鼠和长爪沙鼠种群的数量动态，马尔可夫链模型是比较好的模型。

The corrosion fatigue crack growth and near-threshold characteristcsof high tensile steel HT60 were investigated by using the compact specimens underexposure to synthetic sea water. The da/dN vs △K_ relation in air may be conser-vetivel estimated for that in sea water. In the high △K region with high stressratio, owing to the acceleration of crack growth promoted by stress-induced dissol-ution, the crack opening stress intensity factor K_ represents only the result ofcrack surface in contact with corrosion products, so as to give an overestimation ofK_ at crack tip.

对高拉力钢HT60的腐蚀疲劳裂纹扩展特性和门槛值区域特性，采用紧凑拉伸试件在人工海水中进行了实验和研究，结果表明：在空气中的da/dN与ΔK_关系可以作为在海水中的da/dN与ΔK关系的一个偏保守的预测；在高应力比的高ΔK区域，由于应力诱起溶解促进了裂纹扩展的加速；该裂纹开口应力强度因子K_仅反映了裂纹表面同腐蚀生成物接触的结果，从而导致了K_在裂纹尖端的偏大的估计结果。

In this paper, a thermal simulation model of a LED driver was established. The thermal field and thermal stress analysis of the driver was done by using the software EFD Pro 8.2, and the temperature rise from various parts and the temperature field distribution of the PCB were obtained.
