The main causes were due to accidental falls in elderly, children swimming in waters, followed by falling into the river as the result of disease fulmination and suicidal among adults.

不慎淹溺是主要原因，游泳淹溺是儿童淹溺死亡的第二位原因，因疾病发作跌入河中和投河自尽是成年人淹溺死亡的第二、三位原因。

In writing, we search for and explain the causes and effects, or the main cause and the contributing cause that lie behind it.

在写作中，我们探索和解释种种的原因和结果，或者主要原因或事件背后起关键作用的原因。

Through the analysis and investigation on the present teaching program of the representative 26 universities found at present aerobics major course of specialty of physical educationhave many insufficiency: target oretation is imperfect, neglect skill cultivatement; the curriculum content is irregular, insufficiently attention on the physique and the dancer training and the medical care and the movement damage; The development of functional exercises is current tendency, but has the certain difficulty, the main reason is the equipment is insufficient, generally the investment of aerobics major course is insufficient;Curriculum study is difference, the skill study is few, cannot satisfy the demand to cultivate specialist; The teaching appraisal system is not science, mainly take the end test as the major targets or quotas, pay more attention to technical inspection, neglect its synthesis influence to the students' physical and psychological quality, cann't utilize self-comment, the other comments, mutually comments.

通过对具有代表性的26所高校的现行教学大纲的资料分析、调查发现，目前体育育专业健美操课程存在的不足主要体现在：课程目标定位不完善，忽视技能培养；课程内容参差不齐，不够重视形体与舞姿训练、卫生保健与运动损伤知识；拓展功能健身操是当前的一大发展趋势，但是存在一定的困难，主要原因是场地器材不足，普遍存在着对健美操课程的投资力度不够的现象；课程的学时比例差异大，技能学时偏少，不能满足培养人才的需求；教学评价体系不够科学，主要以终结性考试为主要指标，忽视评价诊断特性和过程性，没有将自评、他评、互评综合运用。

In this paper,the reason arisen from the noise of the BX1 AC arc welder is analysed.For the main factor,moving core viberating,the measure to reduce the noise is advanced from three hands,inside and outside slide.The other measure is also advanced for the second factor.

文摘：对BX1系列交流弧焊机噪声产生的原因进行了分析，针对产生噪声的主要原因——动铁芯的振动，从三个方面、内外滑道分别提出了具体的降低措施，并对次要原因也提出了具体降低措施。

However this does not mean consumers are ignorant parvenus.

在研究方法的部份，主要是运用质化研究的深度访谈法为主，并搭配参与观察法予以辅助，研究发现：在这个族群里的消费者，影响其购买名牌包的主要原因仍是停留在韦伯伦所说的炫耀性消费，但是这并不代表这群消费者是毫无知识、品味的暴发户，这群消费者已开始懂得去吸收名牌的相关知识来搭配自己的消费行为，不过尚属於较低层次的文化资本阶段；另外中间阶层的消费者对於名牌的知识来源主要是经由大众传播媒体所获取，而其他讯息的来源亦会对消费者造成一定程度的影响，不过主要讯息来源仍仰赖大种传播媒体的提供；最后，在社会资本方面呈现出男、女有别的情况，在女性方面，社会资本对於名牌包的消费影响力并非直接提供资源予消费者，而是透过社会资本来延伸消费者的文化资本，但是在男性方面，则表现出截然不同的情况，名牌包对於男性消费者有著工具性消费的意义，男性消费者呈现出一种强烈利用名牌包来达成自己目的的行为。

According to the theory of stress-strain relationship of transverse compressive deformation and wood rheological character, it studies the factors about deformation permanent fixation caused by different methods, and analyzes the component change of wood cell wall caused by four physical treatment methods in this experiment. According to the newest research achievements, it is thought that the absolute release of deformation stress and the effective formation of cohesion inside wood are the main reasons of compressive deformation's permanent fixation.

根据木材横纹压缩应力-应变关系、木材流变学特性等理论对木材压缩及变形固定常用方法对形成变形永久固定的主要原因进行了探讨，根据前人对横纹压缩变形的永久固定理论及本实验中使用的四种物理处理方法在处理过程中对木材细胞壁基质物质的变化和表现出的力学特性的影响进行了分析，结合国内外最新研究成果，认为形成木材压缩变形永久固定的主要原因是木材内部变形应力充分释放和内聚力的有效形成。

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。
