[简答题]一、事故经过
某化工有限公司化工分厂磺酸车间于1992年10月竣工投产,产品为对甲苯磺酸,工艺上布设离心工段,共四台离心机,离心机的作用为磺酸脱酸(硫酸)用。
1号离心机是从某县城郊麻纺厂(现已关闭)购回,该离心机属SS型三足离心机,是用于麻纺产品脱胶用,在本厂使用时间较短,购回时经认定为九成新,当时,配套电机为普通电机,转速为960r/min,后经厂方改造为初速为零、最高速为960r/min的调速电机。该离心机于1994年8月更换了一只转鼓。现已使用两年并历次修理,该离心机其他部件都不同程度的进行过修理或更换部件。
事故当天上午8时,1号离心机调速电机控制器内保险丝烧断,经电工曹某(经培训取证)检查发现主要是调速电机上测速器受潮,渗水引起短路所致。后经拆除由电工曹某在电炉烘干一天。3月4日上午于某(车间副主任)指派电工史某(经培训取证)去安装测试,史用万用表R×1K电阻档测量绝缘程度,指针不动,认为可装,并装好后空试电机时发现调速电机不转,控制器失灵,随即便换上一只新控制器,经快慢反复调试正常后交给班长吕某试机,转速额定50~100r/min,于上午10时左右开始投料生产,由操作工陈某、崔某一组投料四次,出成品约400kg左右,未发生异常现象,在第五次投料完毕后,即下午2时20分左右,离心机突然解体,外套和机座、机脚向西南方向飞出,离心机内衬向东北方向飞出,将当班正在操作的陈某、崔某二人均砸伤,并把距离离心机向4m的吸收工朱某同时砸伤,事故发生后,车间人员立即向厂部汇报,全厂全力救护伤者并及时送往县人民医院抢救。朱某于当日下午4时抢救无效死亡,崔某经县人民医院紧急包扎后在送往南京的途中死亡。陈某于3月5日上午6时在南京第一人民医院全力抢救无效死亡。这起事故造成的经济损失达10.415万元。
二、事故原因
根据对事故的调查分析和专家组的“技术鉴定报告”,调查组认为这起事故是由于设备老化、腐蚀严重且设备的完好性尤其是安全性(安全
系数几乎没有)不能承受离心机工作时突然增大的离心力,因而最终解体造成3人死亡的重大事故。
事故原因分析如下:
1.事故的直接原因

①转鼓与鼓底连结的不锈钢铆钉仅剩总数的1/6,其他代用的螺栓

[单项选择]
Scholars and students have always been great travellers. The official case for "academic mobility" is now often stated in impressive terms as a fundamental necessity for economic and social progress in the world, and debated in the corridors of Europe, but it is certainly nothing new. Serious students were always ready to go abroad in search of the most stimulating teachers and the most famous academies; in search of the purest philosophy, the most effective medicine, the likeliest road to gold.
Mobility of this kind meant also mobility of ideas, their transference across frontiers, their simultaneous impact upon many groups of people. The point of learning is to share it, whether with students or with colleagues; one presumes that only eccentrics have no interest in being credited with a startling discovery, or a new technique. It must also have been reassuring to know that other people in other parts of the world were about to make the same discovery or were t

[单项选择] The Institution of Marriage
The Indians, as all other communities of human beings in every age, in every clime (地域), and in every possible condition in respect to civilization or barbarism, have done, lived in families. That is to say, the husband, the wife, and the children formed a natural group and dwelt together in common. The children were under the care of themselves and the husband and wife, once joined, remained united for life.
Some persons have imagined that the institution of marriage is an artificial institution, adopted by society as an arrangement proved by experiment to be, on the whole, most advantageous to man. But the universality of this institution proves that it is of higher origin. It is a part of man’’s nature, considered as an animal, that he should have one female partner, and that the union which binds him to his partner, when once she is chosen, should endure for life.
