主要原因

This paper believes that the unfavourable natural condition is an important cause of the flood,but it is not the main one.

不利的自然条件固然是水灾发生的重要原因，但不是主要原因。

In this article, a deep going analysis about the history, the present situation and the reason to form that is done in both the formal and informal respects. A conclusion is drawn that erogeneity is the main reason of the unsoundness of rural financial system.

本文从正规金融和非正规金融两个方面，对我国农村金融体系的历史、现状及其原因进行了深入分析，得出现有农村金融体系的外生性是导致其不健全的主要原因。

The main reason and solution: weak reason more to deal with it.

主要原因和解决方法：烫印不牢的原因较多，处理方法也各有差异。

First, the temptation to retire once Social Security benefits can be claimed, at the age of 62, seems irresistible for the majority of workers, even though the payments are actuarially reduced. Second, employers are reluctant to retain or hire older people, mainly because they find it hard to lower their wages if their productivity slips.

原因有二：一，工人到了62岁即可退休，一退休，即可领取社会保障金，多数人都难以抵挡这一诱惑（尽管据保险统计数据，支付给他们的保障金数额实际有所减少）；二，雇主不愿保留或再雇佣年纪较大的工人，主要原因是，这些雇主发现，即使这些人的生产力大不如前了，也很难把他们的工资降下来。

Results In all the deaths related to subarachnoid hemorrhage , the main cause for the cases under 40 years of age was angiorrhexis mostly due to the malformation of the cerebral arteries or veins, while for the cases aged 40 years or more, angiorrhexis relating to atherosclerosis was found to be the primary cause , with ruptures occurring in striate arteries and posterior choroidal arteries.

结果 在本组蛛网膜下腔出血致死的案例中，40岁以下年龄段以脑动静脉畸形血管破裂为主要原因，且以动静脉畸形多见。 40岁以上年龄段，动脉粥样硬化血管破裂为第 1位原因，破裂处为大脑中动脉的豆纹动脉、脉络丛后动脉。

Vascular hyperpermeability is one of the important causein hypovole-mia and organs disfunction after various kinds of shock,and its treatment is still one of the problems in the medical field. For example,the operative methods of preventing hyperpermeability and plasm bleeding is still unreliable after severity burn,and traditional treatment just passively transfuses according to the burn clysis formula instead of inhibiting permeability by injecting drugs. The principal reason is that pathogenesis of vascular endothelial cell permeabilty has not been entirely revealed at the level of molecular biology.

血管通透性增高是休克时有效血容量减少和器官功能损害的重要原因之一，它的防治一直是医学界的一个难题，如在大面积烧伤时，至今未能找到一个简单有效的防治血管通透性升高和血浆渗出丢失的方法，传统的方法只是根据烧伤补液公式测算进行被动的补液来纠正，而不能依靠注射化学制剂来终止其渗出，主要原因是未能从分子生物学水平揭示血管内皮细胞渗出的机制。

Possible reasons for this failure may be that obesity is so physiologically complex that no single gene or even handful of genes is likely to have a dispositive role, that examining gene gene interactions is difficult without large numbers of subjects, and that variations among current candidate genes are not the most important contributors to human adiposity.

其他有明显量的变化的基因很难证明，可能的原因就是肥胖是一个复杂的生理变化过程，单个基因或一部分基因会能起到真正的作用，没有大规模人群实验检测基因相互作用还很困难，而且当前的候选基因变化并不是人类肥胖的主要原因。

Simultaneously, the total extractible myoglobin decreased and the proportion of metmyoglobin increased significantly when the pressure above 400MPa. Beef discoloration after pressure processing may result from oxidation of ferrous myoglobin to ferric metmyoglobin, globin denaturation and structural changes. At 40℃, the changes of beef color was similar to that of room temperature's. When the temperature rise to 60℃, most of muscle proteins denatured, a small quantity of native myoglobin could not affect the color of beef significantly. Therefore, protein denaturation was attributed to the main cause of discoloration in beef muscle after pressurization at 60℃.

压力处理导致色泽变化的直接原因可能是由于二价铁的肌红蛋白氧化成三价铁的高铁肌红蛋白、球蛋白的变性及结构的变化所致。40℃时的压力处理，色泽的变化规律与室温下相似，只是色泽变化的程度更为剧烈，蛋白质变性在色泽变化中起到的作用逐渐加强。60℃下的压力处理，绝大部分蛋白质发生变性，少量未变性的肌红蛋白对色泽不会产生明显的影响，此温度的压力处理，蛋白质变性是造成肌肉失去红色的主要原因。

First, the actuality of Jiangyin bridge's deck surfacing are reviewed. Improper materials and pavement structures, severe conditions, overload and heavy traffic are deemed to be the main factors which result to deterioration of the deck surfacing. Then, programme of local repair asphalt mixture design has been proposed. It is considered that epoxy asphalt mixture and guss asphalt mixture are propitious to the local repair. The epoxy asphalt is also chosen as the adhesive layer material. Next, two pavement structures for steel deck plate surfacing have been tested. The most suitable asphalt surfacing structures have been proposed for the local repair. Finally, the elaborate local repair schemes of Jiangyin bridge's deck surfacing are proposed.

论文首先调查评估了江阴桥桥面铺装的现状，分析了江阴桥桥面铺装破坏的原因，认为材料及结构选用不当、使用条件苛刻、超载与大交通等是主要原因；其次对修复铺装混合料进行了配合比设计，认为优化后的环氧沥青混合料与浇注式沥青混合料适合于江阴桥的铺装修复，而粘结材料则采用环氧沥青粘结剂；然后参考国内外已有的桥面铺装结构组合，对两种复合结构进行了比较研究，提出了适于江阴桥桥面铺装局部修复的铺装结构组合；最后在各项研究的基础上，提出了江阴桥桥面铺装局部修复的具体方案。

Decreasing bone formation may be the main reason for the reducing calcium content in the otoconia. The headward distribution of blood volume may account for the morphological changes in the middle ear and inner ear.

骨形成减少可能是引起耳石中钙含量减少的主要原因；而头部血流量的增多可能是中耳和内耳形态学改变的原因。

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。
