The process of random load action was described with the Poisson stochastic process and the time de pendent reliability models of series system, parallel system and k/n system were developed with the probability differential equation and total probability formula when strength degenerated as time, Taking the degeneration of strength following the exponential rule as an example, the relationships between the reliability and failure rate of system and time were studied.

采用泊松随机过程来描述载荷的作用过程，运用概率微分方程和全概率公式建立了强度随时间退化时的串联系统、并联系统以及k/n系统动态可靠性模型。以强度退化服从指数退化规律为例，研究了串联系统、并联系统以及k/n系统的可靠度和失效率随时间的变化规律。

利用梯度投影与罚函数相结合的技巧，将带不等式和等式约束的优化问题化成一个无约束问题，提出了初始点可任意的求解不等式、等式约束优化问题的摄动梯度投影算法；参数δk取不同的数还可以得到一类梯度投影算法，从而得出了在搜索方向和步长不精确条件下的梯度投影法，保证了在实际应用中更容易实现；在较弱条件下，证明了该算法的全局收敛性。

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。

Therefore,K. pneumoniae CICC 10011 is a potential strain for 2,3-BD production.Thirdly,a novel aqueous two-phase system for the recovery of 2,3-BD from fermentation broth was developed employing isopropanol/(NH_4)_2SO_4 system.The results showed that most of target products(2,3-BD and acetoin) can be partitioned efficiently into the top phase,while most of glucose can be partitioned into the bottom phase.
