The method of vitrification cryopreservation of mouse 2-cell embryos was studied. Several vitrification solutions named EFS30, EFS40, EDFS30 and EDFS40 were prepared. The solution contains ethylene glycol, Ficoll, sucrose and DMSO. Straw method was used to vitrify and cryopreservate in vivo mouse 2-cell embryos at room temperature (20℃ or 25℃). OPS method was used to vitrify the embryo at 25 ℃ or 37℃.

本试验以毒性低、渗透性较强的乙二醇和DMSO为主体，添加聚蔗糖、蔗糖配制的玻璃化溶液(EFS30、EFS40、EDFS30和EDFS40)，在室温(20℃和25℃)下利用细管法，以及在25℃和37℃恒温台条件下OPS法对小鼠2-细胞胚胎进行玻璃化冷冻保存，并对解冻后胚胎的体外培养、囊胚细胞计数及胚胎移植技术进行了研究。

All the results above suggested that it was the cyclic electron transport but the xanthophyll cycle that play the key role in the photoprotection of the rice hybrids. The cyclic electron transport was enhanced under excessive light, thus more ATPs, which could be used for the repair of the damaged D1 protein, would be produced by cyclic phosphorylation.

这些实验结果首次阐明，叶黄素循环的热耗散在杂交稻的光保护中不起关键作用，而环式电子传递则对于杂交稻的光保护起至关重要的作用，其机理可能在于强光条件下环式磷酸化的加剧生成大量ATP用于光破坏的修复作用，同时避免类囊体膜的过度酸化，从而导致强光下qN的下降。

These are main problems of eutrophication.In this paper we selected alga that suits to grow under different concentration of nutrition, after selecting seed, domesticating, culturing alga purely in the lab, we gained Hydrodictyon reticulatum and microalga, most of which are Miorocystis and chlorella.

本文选取在不同营养水平条件下适合生长的藻类物种，在实验室进行选种、驯化和纯化培养，得到水网藻和微藻(主要为微囊藻Miorocystis、小球藻chlorella)；以实验室培养的生长速度快、生产能力高的水网藻为原料，制备一系列环境友好性光敏物质——叶绿素及其衍生物，运用光敏氧化分光光度法测定活性氧(O_2~-，H_2O_2，·OH，和~1O_2)，根据其光敏产生活性氧效率，进行光敏物质的筛选；选用叶绿素铜及其钠盐，以微藻为实验控制对象，以Cu~(2+)作培养对照，在相同光照、营养条件下进行控藻实验。

When the carbon microsphere s are graphitized under the protection of Ar at 2100～2600℃,closed-cell carbon microspheric form of graphitic structure is produced.

依据微胶囊化原理，用热固性线型酚醛树脂制得微胶囊，加热去除囊芯后用作先驱体，在N2保护下进行900~1100℃的碳化处理得到具有无定型碳结构的闭孔碳微球，然后在Ar气保护下进行2100~2600℃的石墨化处理，得到具有石墨结构的闭孔微球碳泡沫材料。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。
