为解决小概率失效结构在可靠度计算中功能函数非线性强、难以显化求解的问题,提出了一种基于优化Kriging代理模型的小概率失效结构可靠度计算方法。首先,引入移动平行四边形网络抽样的方式生成Kriging模型训练的初始样本集,根据插值公式添加结构极限状态面附近的关键验算点,提高样本库的数据质量。其次,采用一种自适应遗传算法对Kriging模型高斯核参数θ进行寻优,建立优化的Kriging结构代理模型。最后,以岳阳杭瑞洞庭湖大桥为工程背景,对悬索桥结构主梁钢桁架考虑竖向挠度失效的可靠度指标计算。结果表明:自适应遗传算法相较于标准遗传算法对Kriging模型高斯核参数的寻优效果更好;优化Kriging模型对主梁挠度响应的预测相对误差均小于5%;与传统有限元模型配合蒙特卡洛抽样的可靠度计算方法对比,可靠度指标相对误差仅为0.52%,提出的优化Kriging模型可靠度计算方法在大幅节约计算成本的同时保证了计算精度,工程实用性更高。

作者：殷素红 wen Ziyun YU qijun MA Yuwei HU Jie School of Materials Science and Engineering South China University of Technology Guangdong Low Carbon Technologies Engineering Center for Building Materials South China University of Technology Guangzhou University-Tamkang University Joint Research Center for Engineering Structure Disaster Prevention and Control Guangzhou University

The thermo-dynamics of reactions between carbonatite and sodium silicate solution at ordinary temperature （25℃） were investigated. The calculated results indicate that at ordinary temperature, the reactions between dolomite, calcite, Ca2＋ and Mg2＋ in carbonatite and H4SiO4, tl3SiO4- and H2SiO42- in sodium silicate solution to form the cementitious products of hydrated calcium silicate or hydrated magnesium silicate all possibly happen; among these reactions, the reactions to form gyrolite （2CaO.3SiO2.2.5H2O） and serpentine （3MgO.2SiO2-2H20） are the most possible to occur. Further, the dissociation degree of dolomite and calcite and the activity of H3SiO4 , H2SiO42- and H4SiO4 ions are the key factors to influence the reactions.

Typical harmful micro-algal species constantly occurred in high density in marine aquaculture ponds in Xiangshan and Sanmen Bay, Zhejiang Province. Fates of the microalgal cells influenced by activity of the cultured animals largely determined the ef fects of the harmful microalgae. However, it is difficult to detect the in situ process. In this paper, toxic activities of three harmful microalga, namely P rymnesium parvum, Pleurochrysis elongata, Karlodinium veneficum, which were isolated from the local ponds, were comparatively studied based on brine shrimp toxic bioassays. Diff erent lethal activities of live cells, cell debris, cellular extracts, and cell free mediums prepared by different process were analyzed. The results showed that,(1) all of the three microalgal species had density and time dependent lethal ef fects on A rtermia nauplii, while P. parvum was the most toxic one and had acute lethal eff ects in 5 h. No such acute lethal eff ects were observed in P. elongata or K. veneficum;(2) live cells, cell debris and cellular extracts of P. parvum had the same lethal pattern. Prymnesins, toxin from P. parvum, is probably not exotoxic active; For P. elongata, toxic activity mainly came from live cells and cell debris; For K. veneficum, toxic activity was relatively lower compared with the other two species. However, Karlotoxin, toxin from K. veneficum, is exotoxic active. Physical disturbance triggered K. veneficum cells actively releasing toxins, which made it an active predator.

Pancreatic cancer is one of the most lethal malignant tumors in the *** advances in diagnosis and treatment,the five-year survival rate for pancreatic cancer patients remains only 9%.1 Pancreatic adenocarcinoma(PAAD)belongs to pancreatic cancer,which occupies 85%of the whole pancreatic cancer.2 Reversible modification of Ne-methyladenosine(m^(6)A)has been shown to be involved in cancer progression,resulting in up-regulation of oncogene expression or down-regulation of tumor-suppressing genes and may affect the prognosis of patients with pancreatic cancer.
