At the end of april , under masters loving instructions , the initiates inspected the site and decided to conduct three projects to improve the dangerous condition of the bridges and paths . the community quickly embraced the projects and expressed their happiness with smiles and a desire to work together to help 4月底，哥斯大黎加的同修带著师父贴心的关怀，再度来到tibas - zurqui dump社区勘查环境，就实地情况拟定三个工程计画，著手改善该区路桥与通行道的危险情况。
Therefore , the safety of bulk carrier is widely concerned ; the theory of insubmersibility is followed by the introductions of domestic and international regulations , solutions , rules and requirements on the floodability ; introduced are the conditions of hold in flooded condition , and provided are the calculation methodology of the stability and buoyancy when flooding . the concept of cargo permeability is concretely defined , and the calculation methods of the amount of flooding waters are executed ; the application of the influence numbers simplify the calculation of the still water bending moment and shearing force in flooded conditions . a new method to calculate the maximum still water bending moment and shearing force is developed by means of the influence numbers ; the simulation system provides a means of evaluation and forecast on ship ' s danger extent after ship is damaged 在抗沉性公式的推导过程中采用一些假设，并分析了这些假设对结果的影响；然后介绍了船舶强度的概念和计算方法，鉴于现有的剪力弯矩计算方法工作量大、效率不高的缺点，引用影响数计算船舶进水后的剪力和弯矩；最后根据船舶抗沉性理论对散货船破舱进水进行模拟，在模拟中根据船舶破舱的实际危险情况，采用直观的图形输入的办法，判断船舶的危险程度并计算船舶到达危险状态的时间以助于船长做出正确快速的决策。
Real time video processing system of intelligent vehicle can detect obstacle to find out the potential danger to vehicle driving . at the same time , surroundings of the vehicle is displayed on lcd and alarm is given out in danger . extremely , the system make the vehicle brake away from danger 车载视频系统实时探测车到障碍物的距离，综合判断车辆行驶的潜在危险性，在显示器上实时显示汽车周围的环境，出现危险情况时报警，极端情况下自动制动，使车辆远离危险。
" our brains are better at picking up subtle warning signs than we previously thought , " said joshua brown , ph . d . , a research associate in psychology in arts & sciences and co - author of a study on these findings in the feb . 18 issue of the journal science 虽然一些学者对人类也同样具有“第六感”的这一说法并不认同，但是美国圣路易斯华盛顿大学的科学家日前经研究证实，人类大脑中确实存在着一个具有早期预警作用的特殊区域? ?这个区域可以监控外界环境线索，同时衡量环境变化可能会给人体带来的后果，并调解人们的行为以避免危险情况的发生。
Even if we have a family , a beautiful family , a good marriage , we still have to pay for it . we still have to work so much in order to maintain this . we work even in the rainy , stormy weather , in a dangerous situation , in our failing health time , in the time when we are exhausted and didn t sleep the whole night because of kids or worry , or whatever , and we still have to work , and no one takes pity on us , no one 我们虽然不停的付出，但却不快乐，苦总是多于乐，即使拥有了美满家庭和幸福婚姻，我们还是必须付出，必须辛苦工作才得以维持一切，甚至要在暴风雨天危险情况身体不适筋疲力尽或彻夜未眠的情形下继续工作，只为了要抚养小孩，或为烦恼担忧，或是别的事等等。
