Study of kinetic antibacterial activities of QJ2 against pathogen W-1 was tested by viable bacteria counts and absorbency at 600nm: 106～ 107 cfu/mL cells of W-1 began to decrease in 15 min after mixing with CFS(cell free-supernatant) of QJ2; the bacterial counts decreased to a minimum at 4h, and the numbers of bacteria began to increase after 6h. The cells of QJ2 did not show any sensitivity to its inhibitory substances in CFS. The size of active molecule in the CFS of QJ2 was smaller than 8000 Da by measuring the inhibitory activities of the fluid inside and outside the dialysis cellulose tubing. QJ2 was identified as Flavobacterium ordaratum by traditional morphological and biochemical method and API-20 identification system.

并对拮抗菌QJ2的拮抗作用进行了研究，结果为：QJ2有广泛的弧菌抗菌谱，对37株弧菌的抗菌阳性率达到89.2%(33/37)；用活菌平板计数法和O.D.600nm研究了QJ2培养物的去细胞上清液与病原菌W-1的作用动力学，15min时W-1的细菌数便开始减少，4h时细菌数最少，6h后开始增加，而对照组的细菌数呈逐渐上升趋势；QJ2对自身的拮抗物质不敏感；QJ2抗性物质的分子量不大于8000Da；经常规生理生化方法和API-20细菌快速鉴定系统鉴定，QJ2为气味黄杆菌。

In this dissertation,we chose some simple ligands as raw materials.A series of metal-organic complex were synthesized under room temperature.Their molecule structures were determined and some relative physical and chemical properties were studied in the purpose of discovering some new phenomena between the structure and NLO properties.It will settle foundation studies for developing this work frothily.

本论文主要以有机磷配体三苯基氧化磷作为起始原料，在温和条件下，设计、合成了一系列金属-有机配合物，测定其晶体结构，并积极开展了一些相关的物理化学性质的研究，努力揭示晶体结构与其二阶非线性光学效应之间的新现象，新问题，为进一步拓展和深化该工作奠定基础。

We took the cultured suspension cells ofPanax ginseng as our experimental material, studied the generation of singlet oxygen whichinduced by fugal elicitor, testified the singlet oxygen acted as a signal molecule in plantdefense responses.

我们以人参悬浮细胞为实验材料，研究了真菌激发子诱导下单线氧的产生情况，进一步证明了单线氧在植物防卫反应中作为信号分子的作用。

"Plus, NAD+ is a fundamental molecule for cell metabolism, so it is known to have relatively low toxicity." In addition, he says, NAD+ loss occurs after PARP-1 activation, meaning that NAD+ might be used later after injury than gallotannin from green tea.

&另外， nad +的是一个根本性的分子细胞代谢，所以它是已知有相对低毒性&，此外，他还表示，与nad +损失发生后， parp的- 1活化，即与nad +有可能被利用后的伤害比没食子，从绿茶。

Treatment under mild condition with solvent of lower polarity was in favor of keeping the molecular structure and properties such as water-solubility, gelatination, etc. Acetyl groups were partially eliminated when purified by Pb2 method, leading to increased crystallinity and glass temperature, which resulted in losts of water-solubility and gelatinability. Owing to the slight oxidative degradation with H2O2 method, the changes of chain size and some functional groups of KGM molecule led to decrease of viscosity and excessive swelling rate.

采用温和条件及低极性溶剂有利於保持KGM本身的分子结构以及水溶性、凝胶性等性能；而Pb2法由於部分脱去了KGM的乙酰基，导致结晶度变大，玻璃化温度升高，最终失去水溶性和凝胶性；H2O2法则由於对KGM造成了氧化降解，也改变了分子链的大小以及部分基团，从而导致粘度降低以及溶涨速度较快。

Glycerate 3-phosphate The phosphorylated form of glyceric acid, a 3-carbon atom molecule.

3—磷酸甘油酸：是甘油酸的3号碳位发生磷酸化后的形式。

The Sulfhydryl content of glycinin and β-conglycinin are increased with the increasing of pressure and prolong of processed time; Fluorescence analysis reveals that glycinin has larger hydrophobic regions while processed by higher pressure; But to β-conglycinin, the hydrophobic regions change according to different pressure; The changes of ultraviolet difference spectra of pressured glycinin show that amino acid residues which have ultraviolet absorbance are exposed on the surface of the protein molecule with its unfolding by high pressure denaturation as well as the exposure of sulfhydryl and dissulfide groups.

处理压力的升高和时间的延长都将使大豆豆球蛋白和β-伴大豆球蛋白的半胱氨酸残基暴露，巯基含量增加。荧光分析表明，经压力处理后大豆豆球蛋白表面疏水区域增多：而对于β-球蛋白，在低压作用下，其疏水区域减少，在高压作用下，其疏水区域增加，但在过高的压力下，β-伴球蛋白中的疏水区域又呈现减少的趋势。
