We used maize seedlings (Zea mays L.) and tobacco (Nicotiana plumbaginjfolia L.) as material. In the first section, we have investigated cold- shock-induced chilling, drought, heat and salt stress resistance in maize seedlings. In the second section, by modifying the Ca~ and CaM levels, we have tried to establish the involvement of calcium messenger system in the cold-shock-induced cross adaptation. In the third section, we have tried to establish a transgenic tobacco system expression CaMICaMIBP genes, so that the others can use it to investigate the process of physiology and biochemistry which endonuclear and cytosolic calmodulin have taken part in.

然后我们讨论了在近等间隔的阶梯型三能级原子系统中，自发辐射诱导相干对其吸收特性的影响，发现利用自发辐射相干也可产生电磁感应吸收。

The results of the investigation showed that the best entrance angle of B〓C, B〓C/ C and Al〓O〓/ C ceramic nozzles is 11°, 14°and 16°respectively. Erosion wear model has been put forward. The B〓C and B〓C/ C nozzles exhibited a stress fatigue induced removal process under the condition of umber emery erodent impacting, and a brittle fracture induced removal process under the condition of white emery and SiC erodent impacting.

建立了不同磨损机理下的冲蚀磨损模型，提出了喷砂嘴的磨损属于多冲蚀机理并存的复合冲蚀机制。B〓C和B〓C/C陶瓷喷砂嘴在棕刚玉磨料的冲蚀下，主要表现为应力疲劳断裂冲蚀，在白刚玉和SiC磨料的冲蚀下，主要表现为脆性断裂冲蚀。

PART 2:The molecular mechanisms of Nontypeable Haemophilus influenzae induced inflammatory response in respiratory epithelial cells Objective:Nontypeable Haemophilus influenzaewas traditionally considered as an extracellular pathogen in respiratory infections.In this study,we established a model of infected cells to confirm NTHI was also a facultatively intracellular pathogen.Mitogen activated protein kinasesare the important signal transduction pathway in mediating inflammatory response induced by NTHI in respiratory epithelium.In this study,we elucidate the impact of NTHI,and its SCF and EP on the expression of MAPK and subsequent proinflammatory mediators.

第二部分：NTHI致呼吸道上皮细胞炎症反应的分子机制研究目的：通过建立呼吸道上皮细胞株的体外NTHI感染模型，确认NTHI在细胞内的存活，观察NTHI及其组分(可溶性胞质成分SCF、外膜蛋白EP)对呼吸道上皮细胞MAPK信号传导通路和后续的前炎症因子表达的影响，并应用特异性ERK-MAPK抑制剂U0126、p38 MAPK抑制剂SB203580特异性阻断下游MAPK信号传导通路，观察它们对呼吸道上皮细胞分泌前炎症因子表达的影响。

The results show that the air crossing pressure pulse magnitude of the container generated in the tunnel is 3.46 times that generated in open air when container flat wagon at the speed of 160 km/h passed by EMU moving at the same speed. Both the lateral force and overturning moment of the container train during the crossing induced in open air and tunnel are approximately proportional to the square of running speed of the passing train. The pressure of crossing side and uncrossing side for the container flat wagon is almost equal since the one-dimensional characteristic of pressure distributing induced in the tunnel is not faintish. Consequently, the value of the lateral force and overturning moment of the container train generated in open air is greater than that generated in the tunnel, about 1.1 times.

研究结果表明：集装箱平车以160 km/h的速度与动车组等速交会时，在隧道内会车时车载集装箱中部压力变化幅值是在明线会车时的3.46倍；在明线和隧道内会车时，集装箱列车受到的侧向力和侧滚力矩均与交会列车运行速度近似成平方关系；因隧道内压力分布一维特性较强，集装箱平车交会侧与非交会侧压力相差并不大，因此，在明线会车时集装箱平车受到的侧向力和侧滚力矩均比隧道会车时的大，大约是其1.1倍。

ERAF17 gene expresses differently between male and female reproductive organs. Its expression is induced by ethylene or ethylene released compounds that can promote femaleness. No evidence directly shows the relationship between ERAF17 gene and femaleness, however. So this work focus on proving the positive correlation between the expression of ERAF17 gene induced by ethylene and development of female flowers,then search for the signal pathway of cucumber female reproductive organ development.

ERAF17基因在黄瓜的雌雄生殖器官的表达不同，可以由乙烯诱导表达，从而推动雌性化，但是它的作用机制却不清楚，并没有明确的证据表明ERAF17基因与雌花的发育有直接关系，所以本论文研究重点在于证明乙烯诱导ERAF17基因的表达对黄瓜雌花的分化有确定的正相关，从而可以探索黄瓜雌性器官发育存在的可能的信号通路，并对应用前景进行评估。
