[简答题]
2010年1月18日0时15分,由于外线电路进线发生电压波动,导致某化工厂聚氯乙烯分厂8×104t/年聚合装置B聚合釜搅拌停止、冷却水停供。8×104t/年聚合装置当班班长聂某、主操作工龚某、副操作工詹某、巡视工徐某4人在控制室,另一巡视工康某;B釜已反应2小时16分;C釜反应结束等待出料。
龚某首先从集散控制系统(DCS)显示器上发现动力设备停电,遂报告聂某,并让徐某到47号变配电室值班室找人。聂某打电话通知聚氯乙烯分厂调度王某,汇报停电及装置情况。徐某到变配电室,向电修当班班长赵某申请给聚合釜搅拌及循环水泵送电,然后跑到现场B釜处等待搅拌的启动。
聂某见电仍然没有送上,再次跑到变配电室中请送电,然后和康某一起到现场,将B釜的循环水调节阀手动全开,回到控制室,聂某发现B釜压力仍在迅速上升,通知操作工往B釜加稳抗剂,因断电,稳抗系统未能启动,随后又再次去变配电室要求送电,此时王某正在要求赵某与另一名值班电工许某一起送电。由于操作不当,送电未能成功。
聂某见状随即跑回主控室,此时B釜压力已达1.3MPa(正常反应压力1.1MPa),决定将B釜排气管线阀门打开,向出料槽排气泄压。此时聚氯乙烯分厂值班人员(8×104t/年聚合车间副主任)黄某也赶到操作室,见正在排气,便到现场确认,并将步话机交与徐某,让其与控制室保持联系。
当B釜釜压达到1.4MPa,龚某提醒聂某往B釜加入紧急事故终止剂,聂某通知现场巡视工打开氮气钢瓶阀门,现场人员发现钢瓶氮气压力不足,黄某、徐某、康某3人迅速卸下2个旧钢瓶,同时跑到20m远处搬回2个新钢瓶。聂某此时也赶到现场,4人一起将氮气钢瓶换好。聂某迅速跑回控制室,见此时釜压已升到1.6MPa,他立即按下了B釜紧急事故终止剂加入按钮,同时听到了一声巨响。控制室人员迅速躲在DCS操作台下;响声过后,人员跑出控制室,聂某及龚某又返回控制台,按下了A釜、C釜的紧急事故终止剂加入按钮,然后撤离现场。现场人员也迅速撤离了现场。
事故发生后,公司当班调度主任赵某在18日0时44分向119报警,并命令停止氯化装置单体输出,关闭相关阀门。当班调度及公司办主任孙某用电话分别通知公司领导,1时5分,公司领导相继到达事故现场,进行指挥。全厂所有装置陆续停车。
事故发生后,

[填空题]An earlier survey identified 22 "coping" strategies that parents resorted to when they couldn’t sit down with their families to eat a meal that was prepared at home. These including skipping meals altogether, eating at work, eating in the car, ordering take-out on the way home from work, choosing easy and quick-fix meals to serve or overeat after a missed meal.
The 69 low-income wage earners in the first study admitted to skip meals or not eating at home because of time constraints and for financial reasons. In the current study, we found that half of the mothers and fathers surveying depended on 12 of the 22 mealtime coping strategies. We know that when people cat together as family, diets of both the parents and the children tend to be better. But often our jobs don’t allow us to eat together at home as often as we’d like.
The issue is not simply a matter of what we eat, but how we eat. Long and regular work hours are a primary cause of unhealthy eating habits, and for

[填空题]Do animals have rights This is how the question is usually put. It sounds like a useful, ground- clearing way to start. 71. Actually, it isn’’t, because it assumes that there is an agreed account of human fights, which is something the world does not have.   On one view of rights, to be sure, it necessarily follows that animals have none. 72. Some philosophers argue that rights exist only within a social contract, as part of an exchange of duties and entitlements. Therefore, animals cannot have rights. The idea of punishing a tiger that kills somebody is absurd ,for exactly the same reason, so is the idea that tigers have rights. However, this is only one account ,and by no means an uncontested one. It denies rights not only to animals but also to some people―for instance, to infants, the mentally incapable and future generations. In addition, it is unclear what force a contract can have for people who never consented to it: how do you reply to somebody who says "I don’’t like this co
