After Cryopreservation of embryo and larvae of pacific oyster Crassostrea gigas, the results indicate the survival rate of trochophore larvae is 61.1% and significantly better than that of other stage embryo or larvae(P.05).The effect of high sucrose density is better than that of low sucrose density with the same DMSO density.

对太平洋牡蛎的胚胎和幼虫的超低温冷冻保存发现，担轮幼虫的解冻复活率最高，达61.1％(3.0M DMSO)，显著高于其他发育阶段幼虫的保存结果(P＜O.05)；牡蛎担轮幼虫的保存结果显示，在相同DMSO浓度条件下，高蔗糖浓度组保存效果好于低蔗糖浓度组，但差异不显著(P＞0.05)。

The structure of uncured mix and vulcanite, physical and chemical interaction between filler and matrix, mechanical property of composites were investigated It was found and explained that the compact relationship among bound rubber, cross-linkage density and physical property in mineral filler/silicone rubber composite In detail, BR〓, D〓(cross-linkage density using basic solvent as swell liquid) and module have direct relationship, because they all show chemical interaction between filler and matrix from different angles, respectively BR〓(bound rubber in toluene solvent), D〓(cross-linkage density using toluene solvent as swell liquid) and tensile strength have compact relationship also, because they all show total interaction from different angles, respectively

研究了未硫化胶和硫化胶的结构、填料与基体的物理化学作用、及这些结构和作用的表现形式，发现和解释矿物填料/硅橡胶复合材料中结合橡胶、交联密度与复合材料的力学性能密切关系。具体说，BR〓、D〓和弹性模量均从某个侧面反映复合材料中填料与基体间的化学作用，三者的关系比较密切：BR〓、D〓和抗拉强度均反映复合材料中填料与基体间总体相互作用，三者的关系比较密切。

On the other hand, through the discussion on coronal density of flares, we found that the column mass density at the top of chromospheric flare model can not be represented the total mass above the chromosphere and the coronal density can be estimated from presure balance based on semiempirical model. Through estimations, the results show that the total mass above the chromosphere is about the same as the mass between the top of chromosphere and electron source, which so give an evidence that the source of electrons is situated at the top of flare loop.

另一方面，通过对日冕物质密度的讨论发现，半经验模型中色球顶部柱数密度不能用来代表耀斑环在日冕内的总物质，日冕物质密度可用日冕气压与半经验模型中色球顶部压力近似相等来进行估计，进而发现耀斑环在日冕内的总物质与前面估计的色球顶部到非热电子源之间的总物质近似相等，结果趋向于支持非热电子源位于环的顶部。
