In the 1970s and 1980s, facing an ever-intensifying nuclear arms race between the United States and the Soviet Union, and tens of thousands of nuclear warheads, which, like dark clouds, hung over the heads of all people in the world and directly threatened China's safety, China had no other choice but to continue to carry out research and development of nuclear weapons technology and improve its nuclear weapons systems, mastering in succession the neutron bomb design technology and the nuclear weapon miniaturization technology.

70年代和80年代，面临着愈演愈烈的美国、苏联两国空前的核军备竞赛，数万枚核弹头的阴云笼罩在世界人民头上，也直接威胁到中国的安全，中国不得不继续研究发展核武器技术和改善自己的核武器系统，并先后掌握了中子弹设计技术和核武器小型化技术。

If that is indeed how things play out, the five countries that collectively proved unable or unwilling to stop Mr Kim's nuclear delinquency before his provocative nuclear test last October will have compounded failure with folly: encouraging nuclear wannabes to believe that the more rules they break, the bigger the eventual pay-off; and in the process eviscerating the Nuclear Non-Proliferation Treaty and setting off a dangerous series of nuclear chain reactions, from East Asia to the Middle East.

如果真的就这样结束的话，这五个国家将会犯下更多的愚蠢的错误（在去年十月份朝鲜进行核试射之前，他们并没有或者说并不愿阻止金正日的核计划）：这将会鼓励那些希望拥有核武器的国家相信规则破坏得越多，获利就越多，他们会继续使《核不扩散条约》的威信荡然无存，届时从东亚至中东会触发/引发一系列危险的核&多米诺&效应。

The results show that: 1 supplementation of protein to maturation media improves cumulus expansion in vitro compared to the protein-free control, but cumulus expansion is not necessarily related to oocyte nuclear maturation in pigs, and cumulus expansion is not the criterae for determination of nuclear maturation of pig oocytes, but only the exclusion of the first polar body; 2 exposure of pig COCs to hormone supplements for 23-24 hours improved cumulus expansion but had no significant effect on nuclear maturation compared to that for 46-48 hours; 3 under our research conditions, supplementation of different proteins into different maturation media has different effects on porcine oocyte nuclear maturation, but has no significant effect on subsequent embryonic development after IVF; 4 the nuclear maturation rates of pig oocytes matured in mTCM+pFF and mNCSU+pFF are superior than that in mNCSU+FCS; 5 different maturation media have no effect on pig oocyte cumulus expansion and subsequent embryonic development after IVF.

结果显示：(1)在成熟液中添加蛋白质可以加强卵丘细胞的扩散，但猪卵母细胞的核成熟与其周围的卵丘细胞扩展没有必然的联系，卵丘细胞扩散或成放射状不宜作为猪卵母细胞核成熟的标准，只有排出第一极体才能作为猪卵母细胞核成熟的标志；(2)在猪COCs的46-48小时成熟培养的后23-24小时阶段去除成熟液中的激素不但可以保证卵母细胞的核成熟率，而且可加强卵丘细胞的扩散；(3)在现有实验条件下，在mTCM和mNCSU中添加10％pFF与在mNCSU中添加10％FCS相比可获得较高的猪卵母细胞核成熟率；(4)在不同的成熟液中添加不同的蛋白质对猪卵母细胞核成熟率的影响效果不一样，但对体外受精后的早期胚胎发育影响不明显；(5)成熟液种类对猪卵母细胞的卵丘细胞扩散和体外受精后的早期胚胎发育无显著影响。
