主要原因

Reasons of caustic soda concentration abrupt decrease in late period of graphite anode electrolyzer and metallic anode electrolyzer operation were discussed.

对石墨电槽和金属槽运行晚期碱浓度突然降低的原因进行了探讨，认为导致碱浓度降低的主要原因是隔膜的性能和组织成分发生了质的变化，丧失了正常工作的效能。

Enteritis, the main reason is as follows

肠炎的原因较多，主要原因如下

According to the structure and work principle of the bore evacuator and the principle of combustible cartridge case , the main reasons of the fire in combat room are low reliability of bore evacuator and incomplete combustion of combustible case.

根据某自行火炮抽气装置结构与工作原理以及可燃药筒燃烧机理，得出抽气装置抽气可靠性差与半可燃药筒燃烧不完全是战斗室失火主要原因，给出了抽气装置抽气可靠性计算模型，并分析了影响抽气装置抽气可靠性诸因素，提出了该自行火炮抽气装置结构改进建议；分析了半可燃药筒燃烧不完全原因，提出了半可燃药筒制造与验收及使用注意事项。这对于自行火炮的设计与使用均有一定的参考价值

Lack of time is the main reason for this failure (remember that we, the Evince development team, are all volunteers), but it's not the only one.

时间不够是这次失败的主要原因（不要忘记，我们，Evince 的开发团队，是志愿者），但是并非全部原因。

Proofs that when iterating with the BP algorithm, if one of the neural units fall into saturation regions at least, and the other one at least don't, then the condition number of the Hessian matrix of the error function is very larger.

证明了BP算法在迭代过程中，如果至少有一个神经元落入饱和区而同时至少有一个没落入饱和区，则目标函数的Hessian阵的条件数变大，这是导致"网络瘫痪"现象的原因，也是BP算法收敛速度慢的主要原因。

The cause that causes educational inequity admittedly a lot of, but public policy is one of main reasons.

造成教育不公平的原因固然很多，但公共政策是主要原因之一。

Underreporting, rather than infrequency, represents the main cause for this limited data, in part due to the lack of centralized databases.

报道不全是这些数据有限的主要原因，而并非发生罕见，其原因部分是由于中央数据库的缺乏。

However, it was soon noticed that it was difficult to put the principles of justice, sustainability and intercommunity in practice, a great number of the programs and projects put by the member states of the international community can not be implemented.

这体现着现有可持续发展理论研究的一个缺陷：把导致发展困境的主要原因归结为一般的生产力发展、科技进步或人性的普遍弱点，却在一定程度上忽略了社会关系和社会制度方面的原因。

The interaction is the major reason for nucleation site's intermittency.

核心间的相互作用是导致核心核化状态出现间断性的主要原因，另一个原因是主流体的对流冷却。

In recent years, because the sulfur corroded accidents and so on refinery which, storage and transport equipment revelation occurred to occur frequently, created the huge economic loss to the enterprise, the analysis accident cause factor discovered that the iron pyrites spontaneous combustion was the primary cause which the initiation exploded.

近年来，由于硫腐蚀而发生的炼油、储运设备泄露等事故频繁发生，给企业造成巨大的经济损失，分析事故原因发现，硫铁化物的自燃是引发爆炸的主要原因。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
