However, the characteristics that the multiple constraints and sequences in the auto-body assembly make the error stack-up very complex and it is difficult to search dimension-loop by utilizing the traditional dimension loop model in the 3-D variation analysis and synthesis in auto-body. Meanwhile, for the auto-body composed by great mounts of parts, the traditional Monte Carlo Simulation is time-consuming.

然而，车身装配过程中零件间的多约束特征和多装配顺序影响，使得车身装配偏差累积规律十分复杂，传统尺寸链分析方法需要建立尺寸链方程，难以适应车身三维偏差分析；同时，传统的蒙特卡洛求解方法计算效率低下，难以应用于这种复杂车身产品的公差综合。

They argue that compared with that in the western world the living stander of the Chinese people, especially in the poor, rural areas is still low.

他们争论说与西方国家比较中国的人民生活水平，尤其是在贫穷和落后地区，人民生活水平较为低下。

But the World Trade Organisation's poorer members, led by India, are reluctant to cut tariffs much on a category of "special products". This is supposed to be limited to staple goods—such as rice, wheat, onions and poultry—on which the poor depend for their nourishment and vulnerable farmers depend for their livelihood.

但是世界贸易组织里由印度牵头的贫穷的成员国却反对对某类"特殊农产品"，这大致包括大米、面粉、洋葱和家禽，对于那些贫穷的农民而言，他们以倚赖这些物质获取营养，而对于那些经济能力低下的农民而言，他们则赖此获得生存。

However, almost all the current theories for climate prediction, including the ones in statistics and nonlinear science, are based on assumption that the process is stationary which is contrary to the nature of the climate process.

在大气运动中，气候正是一个典型的非平稳系统，但是现有的气候预测理论，包括统计预测理论和非线性预测理论，几乎都无一例外地建立在平稳性假定的基础之上，这有悖于气候过程的基本性质，因此它有可能是导致气候预测水平低下的重要的理论原因。

Why is it that some groups of people still hunt animals, wear little or no clothing, have little or no technology, while others are very sophisticated in their technology, industry, transportation, communication, food gathering and storage?

为什么有些群体的人仍然衣不蔽体，文化科技低下，过着原始的狩猎生活，而另一些群体的人却拥有着尖端的科学技术、先进的工业、交通运输、通讯、先进的食品加工与储藏技术呢？

In the first part, the opinions and ideas from some main figures concerning the North-western regions in modern history; In the second part, the process of three vital stages(Yang-Wu Movement, the "New Deal" in the last period of Qing Dynasty, Anti-Japanese War) are studied, and the characteristics of each stage are generalized falling into four categories, such as: military、feudal、comprador and nation-monopoly etc; In the third part, four reasons of the low efficiency of the industrial and mineral exploration are explored, they are the dominant role natural economy, the low level of productive forces, the science and technology, lack of capital accumulation and investment, lack of systematic policies and support from the government, In a word, as Mao Tsetung said:"It"s impossible to get rich, develop industry, strengthen national defence in semi-colonel and semi-feudal China.

全文共分四部分，第一部分论述了近代一些主要的阶级关注西北的言论和思想；第二部分对西北近代工矿业开发的三个最重要的阶段，即洋务运动时期、清末"新政"时期、抗日战争时期的开发过程做了梳理，并对每一个阶段的特点做了初步地概括，大致可以归纳为军事性、封建性、买办性以及国家垄断性等；第三部分对西北近代工矿业开发成效不高的原因做了论述，主要有四点：第一，小农业与家庭手工业紧密结合的自然经济占统治地位；第二，生产力水平低下，科学技术落后；第三，缺乏资金的积累和投入；第四，缺乏政府系统的政策支持和保障。

Both foreign and, more strikingly, domestic investment are very low compared with China.

与中国相比，外国投资和更加明显的国内投资的数额都相当低下。

Acting, therefore, as his interpreter and summarizer, I gather that in the course of an imprisonment of seven years he has himself modified his own personal views, both as regards Women and as regards the Isosceles or Lower Classes.

代理，因此，他的翻译和summarizer，我推测，在一个7年的监禁，他本人也改变了他个人的意见当然，无论是妇女和至于等腰或低下阶层。

If he is full of impeding attachments, he is just a supercilious man.

There has been much less reform among Japan's huge swathe of inefficient, domestically oriented companies.

而在日本大量效率低下的内向型大公司中，实施改革的寥寥无几。

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。
