Although the profusion of temporary contracts has brought greater flexibility, it has laid the burden of adjustment disproportionately on the low-skilled, the young and immigrants.

虽然大量的临时雇工为市场带来灵活性，但却增加了协调低技术人才、年轻劳动力及移民的负担。在欧洲，移民占劳动力的比例渐增，这亦增加了一个引起失业的不确定因素。

The capillary absorption of water under unsaturated state is an important factor causing the degradation of building materials. It also induces the corrosion of reinforcement.

非饱和建筑材料的毛细吸水过程是造成建筑材料性能劣化的重要因素，它还将引起钢筋锈蚀。

The deuterium enrichment in electrolysis cell will finally cause a poor deuterium extraction efficiency, and this conflict indicates that dynamic behavior of CECE is a main concern in the choice of operating mode and the connection with cascade post-enrichment sysytem, and it should be an important factor in designning catalytic exchange column.

电解池中氖浓度的增长最终将引起交换系统脱氚率的下降，这一现象表明，在交换系统操作模式选择以及与后级浓缩系统的级联匹配中，对交换系统的动态行为必须予以特别关注，并应在交换床设计中考虑此因素。

Using the models, the author has also calculated the vibration response to high speed railway vehicles of three types travelling over simply-supported beam bridges with various span lengths respectively. Based on the analysis of the computation results, the concept of resonance velocity of a bridge under a high speed running vehicle is present, and it is pointed out that comparatively great vibration of bridges on high speed railways is caused by bridge resonance resulted from the static force pulsating. In a vehiclebridge coupling vibration system, the damping constant of the axle spring is the main factor affecting the response variable of bridge velocity resonance, and the influence of track irregularity on bridge vibration on high speed railways is rather smaller.

利用所建立的计算模型，计算了三种形式的高速铁路车辆通过各种跨度简支梁桥结构时的振动响应，对所得到的计算结果进行了详细的分析，提出了高速行车下桥梁共振速度的概念并指出高速铁路桥梁产生较大振动的原因是静力脉动引起桥梁共振造成的；通过研究车—桥耦合振动系统方程的参数后指出，在车—桥耦合振动系统中，车辆—系阻尼的大小是影响桥梁速度共振时响应大小的主要因素，轨道不平顺对高速铁路桥梁振动的影响较小。

Through screening and comprehensive analysis of childhood lead poisoning caused by automobile exhaust pollution is the main factor, as automobile exhaust lead dust accumulation in more than one meter above the ground, and that is exactly the children's activities with the breathing zone of pollution caused by it has become one of the major causes of childhood lead poisoning.

通过筛查和综合分析，造成儿童铅中毒的因素主要是汽车尾气污染，由于汽车尾气铅尘多积聚在地面以上1米的范围，这正好是儿童的活动与呼吸带，它所引起的污染已成为儿童铅中毒的主要原因之一。

The main results are as follows: The environment here is terribly vulnerable, and is facedwith the severe process of desertification and pasture degradation. The tendency of climatebecoming warmer and arider is the background factor of the environment degradation, and theinfluence of the human activities also expedites the process. The main reason that results inthe regional difference of the landscape changes is the the regional difference of the intensityof human activities.

研究结果表明：鄂托克旗生态环境十分脆弱，土地沙化、草地退化问题严重；气候朝干旱化与温暖化方向发展的趋势是生态环境退化的背景因素，人类活动的影响加剧了这种退化过程；不同景观小区人类活动强度的差异是引起景观变化差异性的主要原因。

The scientists have dissected and just found the factor which cause the death through the corpse : Encroached on by a series of noxious substances , make its immune system suffer serious destruction, these belugas suffer from diseases , such as gastric ulcer boring a hole , hepatitis , lung abscess ,etc.; What is more, some belugas have suffered from the bladder cancer, this was really had never heard of in cetacean's animal.

科学家们经过尸体解剖才找到了引起死亡的因素：由于受到一系列有毒物质的侵害，使其免疫系统遭到严重的破坏，这些白鲸患上了胃溃疡穿孔、肝炎、肺脓肿等疾病；更有甚者，有的白鲸患了膀胱癌，这在鲸类动物中真是闻所未闻的。

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