尼日尔是世界第五大铀生产国，但至今还没有建设出一个反应堆，因为光建造费用就超过其GDP的一半。
Niger may be the world's fifth-largest uranium producer, but the cost of building a reactor to make use of it would take up more than half the country's GDP.
其原因也许在于童年时期感染幽门螺旋杆菌能让免疫系统学会适当地反击外源抗原，这样长大后就不会因为反应过激而出现哮喘。
It could be that encountering Helicobacter as a kid teaches the immune system how to react, and not overreact as in asthma to future allergens.
他们认为，形成这种局面不是因为AECL未能按其承诺建造反应堆，而是核管理机构要求AECL应该信守承诺。
The stalemate, they argue, is not due to AECL's failure to deliver the reactor that it promised, but rather the nuclear regulator's demand that AECL should be held to that promise.
因为尽管日本的坚定立场得到美国，英国和法国，包括其他国家的支持，但他反应的夸张程度使国际社会甚至一些其支持者感到不安和忧虑。
For though Japan's toughness drew praise from America, Britain and France, among others, an element of hyperbole in its reaction unsettled even some supporters.
核废料应保留在核反应堆的冷却池，这意味着所有核电厂将不得不关闭，因为其冷却池都满了。
Nuclear waste should be retained in the cooling pools of the nuclear reactors, meaning that all nuclear power plants would then have to close because their cooling pools are full.
UPGMA聚类分析和NMDS散点分析表明，水解、好氧反应器内的微生物并没有因为同处一个系统内而使得其菌群落结构产生明显的趋同倾向。
Cluster analysis of DGGE by UPGMA and NMDS analysis suggested that microbial structures in two reactors did not evolve in the same direction obviously although they worked in the same system.
锌对焦炭强度产生影响的原因是锌促进焦炭的溶损反应，锌并不会因为吸附到焦炭上而直接对其强度产生明显影响。
Zinc is a catalyst for loss reaction of coke to promote the solution loss reaction, Zn will not directly impact on its strength.
