The tension stress distribution of the aerostat envelope under windless condition is obtained using the FE model, and critical regions with high stress are pointed out. The calculated value of tethering force fits well with the theoretical one. The results are instructive for the safety evaluation and design of aerostat structures.

应用此技术建立了无风载条件下浮空器囊体张应力分布的有限元分析模型，给出了囊体的张应力分布情况并指出危险应力区域，对系留力的计算值与理论值吻合较好，计算结果对浮空器结构安全评估及设计具有一定的理论指导意义。

The intraperitonealLD_(50) values in mice of VES and VDPG were 0.16mg/kg and 0.39mg/kg,respectively. The intraperitoneal LD_(50) value in cockroach of VDPG andVES were 2.32μg/g and 1.87μg/g, respectively.

Megaspore mother cells undergo meiosis, which results in the formation of 4 megaspores in a row. The chalazal-most cell develops into an 8-nuclei embryo sac after 3 rounds of mitosis. A mature embryo sac is produced after cellularization and nuclear migration.

结果表明：1大孢子母细胞经过减数分裂形成直线排列的4个大孢子，其中珠孔端的3个大孢子退化，合点端的大孢子进行3次有丝分裂，形成八核胚囊， 8个核迅速细胞化，最终发育为成熟胚囊。

The cleavage rate of 2-cell stage was 50%, but few embryos developed into morulas and blastocysts (2%). More than 130 embryos at 2-4-cell stage were transferred into oviduct of 13 synchronized foster rabbits and 2 mice. No fetus or implantation sites were observed in both recipients.
