An ecology-epidemic model which takes into account the effective contact rate relying on the total number of persons is proposed and the expression of the threshold value R0 is extracted on the invariant subset.

研究了具有依赖于总人数的有效接触率的生态-传染病模型。建立了一个具有依赖于总人数的有效接触率的模型，在模型的不变子集上先求出阈值R0的表达式。

By using Pontryagin minimal principle to minimize the action, a partial differential equation for the Lagrangian is obtained and solved. For this action, it can be verified directly that the inverse square law is the corresponding optimal controller. Finally, the generalization of this mechanization is presented for more complicated dynamical systems.

此一方程的解虽有无限多组，然其中一组的解为该系统的行动能量是总能量，所显示的物理意义为大自然若采取平方反比定律为最佳控制器，其目的在维持物体沿特定轨道运动的总能量为固定。

The method is before interpose, hind use proper motion to design average project questionnaire, Ai Sen to overcome individual character to measure questionnaire , the " that is like planning deals with means questionnaire ", 260 medical personnel that execute maritime rescue mission to 5 batch undertake investigating, serum determines in the meantime always 3 iodic thyroid former acid (TT3), total thyroid element (TT4) and coriaceous alcohol level.

The chemical speciation of VOCs in indoor air was similar to the outdoor, and the dominant species were isopentane, benzene, toluene, propanal, propene and dichloromethane.

结果表明，室内总VOCs浓度高于室外，烷烃是含量最丰富物种，平均占室内外空气中定量VOCs总浓度的32.8%。

The comparisons of biochemistry between OP and OR rats The differences between OP and OR rats included not only body weight, but lipids metabolism and insulin sensitivity as well, characterized with insulin resistance, increasing in serum free fatty acids and ketone body, and hepatic TC and TG in OP rats. However, no significant differences were observed in serum TG, TC, LDL, HDL and fasting glucose between OP and OR rats.⑶Comparisons of metabolites in serum, urine and liver tissue between OP and OR rats①There were significant differences in amino acids concentration between OP and OR rats,especially in liver tissue, such as high concentrations in ketogenic and glucogenic amino acids in OP rats, suggesting differences in amino acids metabolism;② The different metabolites between OP and OR rats included increasing of various saturated fatty acids and decreasing of polyunsaturated fatty acids in OP rats;③The urinary metabolites analysis indicated that different structure or metabolism of gut microflora might exist between the two phenotypes, which probably influenced the regulation of body weight gain;④The end-products of catecholamines in urine and intermediates of krebs cycle in serum in OP rats were all up-regulated, suggesting that the activity of sympatheic nervous system and energy metabolism was higher in OP rats than OR rats.

胰岛素耐受实验和胰岛素敏感指数表明OP动物的胰岛素敏感性较OR动物下降，而OP大鼠血清中游离脂肪酸、酮体、肝脏总胆固醇和甘油三酯水平显著升高；但是，OP与OR大鼠血清中总胆固醇、甘油三酯、低密度脂蛋白、高密度脂蛋白和空腹血糖等的水平并无显著性差异；⑶肥胖易感与肥胖抵抗大鼠血清、尿液和肝脏组织提取物中代谢物的比较研究表明：①OP与OR大鼠的血清、尿液和肝组织提取物中多种氨基酸的含量存在显著差异，并以肝组织中的差异氨基酸数量为最多，包括各种生酮和生糖氨基酸水平在OP组的升高，说明氨基酸代谢的差异是两种体重表型大鼠之间存在的重要差异特征之一；②OP与OR动物肝脏和血清差异代谢物中包含多种饱和长链脂肪酸的升高如十四烷酸、十六烷酸、硬脂酸等和多不饱和脂肪酸的下降如亚油酸和花生四烯酸，说明两种体重表型动物的肝脏脂肪酸代谢存在明显差异；③长期高脂饮食喂养后，动物的尿液代谢物分析表明OP与OR动物体内的肠道菌群结构存在差异，这些菌群上的差别可能在动物体重增长的调节上产生影响；④与OR动物相比，OP动物尿液代谢物中儿茶酚胺类递质的代谢终产物如高香草酸、扁桃酸和4-羟基苯乙酸明显升高。
