The modernization city bring the problem of the environmental deterioration,here the deterioration is being build more and more buliding and the air being polluted by the unprimitive industry.People can't touch the ture nature,there more people choose to go into the groggery,ktv,and even some person consider gamble to the way of killing time.The trend of traffic accidents,family violence and many society's destabilizing factors will increasing instead of reducing pressure.

城市的现代化也带来了城市环境的"恶化"，这里的"恶化"指得是高楼地不断拔地而起，空气被工业的发展所污染，人们能接触到的真正的自然环境正日益在缩小它的范围，人们能选择的休闲方式也从大自然中走到了酒吧，KTV，甚至有的人以赌博作为自己的休闲方式，这些休闲方式往往会让交通事故，家庭暴力以及很多社会不安定因素成上升趋势，而并非能真正起到减少压力的效果。

Similar to the Interior Gateway Routing Protocol, OSPF was created because in the mid-1980s, the Routing Information Protocol was increasingly incapable of serving large, heterogeneous internetworks.

But,in the variable se lection is a limitation,i.e.not all the selection variables have a significant contribution in the models.

同时，在这些应用中也反映了遗传算法在变量选择中存在的局限性，即不能保证选择的所有变量在模型中都有显著贡献。

I hope the above demonstrated that the new system is really much easier as well as more logical in use, but choice is better than no choice and some people might have legacy data (although I will tell you that I was unable to access the data I had encrypted under Mandrake with any system other than Mandrake, so if you are contemplating a move this might be the time to adopt the new standard).

我希望上面展示的新系统真的在使用上更简单更具有逻辑性，但是选择总比没有选择好而且有人可能有遗留的数据（虽然我将告诉你我用任何非Mandrake系统不能获取任何在Mandrake下加密的数据，所以如果你正在考虑，这也许正是时候来采用这种新的标准）。

This thesis takes the strenuous search for cultural identity of the Dead family in Song of Solomon as the main line, embarks on the cultural identity of blacks in different periods, connects the pursuit of identity with their history in American society, outlines a vivid historical picture of blacks from the evolution of their identity (from the enslaved black to the emancipated freedman, to the northern migrator and then the youth born in the north), further explores the efforts made by the blacks on their way to seek their national outlets and build their cultural identity in different periods, points out the advantage and disadvantage of their choice, and finally draws to the conclusion that African American should not abandon their national tradition but at the same time they must stand on American society and find a sound integrity of the two cultures.

本论文以托妮·莫里森的第三部小说《所罗门之歌》中戴德家族寻求文化身份认同的艰难历程为主线，以黑人在不同的历史时期的文化身份的选择为切入点，把黑人对身份的探寻与他们在美国社会中的历史文化联系在一起。从黑人身份的演变(从奴隶到被解放的自由人到北方移民者到出生在北方的新一代黑人青年)勾勒出一幅美国黑人百年历史的生动画面，分析在不同时期黑人为寻求民族出路和构建文化身份时所做出的艰苦卓绝地努力和探索。同时也指出了他们所选择道路的利与弊。最后的结论是：在寻求种族出路时既要立足美国现实又不能抛弃种族传统，而应该努力找到二者的最佳结合点。

According to the requirements of economic operation transformer if capacity choices too small will cause transformer overload operation may lead to transformer burned; choice if too much capacity a "big Kumaratunga car" phenomenon can not make full use of transformer capacity unladen loss increase .

根据变压器经济运行的要求，如果容量选择太小，会引起变压器超负荷运行，可能导致变压器烧毁；如果容量选择太大，出现"大马拉小车"现象，变压器容量不能充分利用，空载损耗增加。

Centerless grinding is a important way of processing in industrial production,the traditional grinding parameters are determined through the technology handbook and own actual processing experience,choice quality depends largely on the level of technology staff,so that the choice of parameters can not achieve the best.

无心磨削是工业生产中一种重要的加工方式，传统的磨削参数都是由磨削工艺人员通过查询相关的工艺手册并结合自身的实际加工经验选择确定，选择的好坏在很大程度上取决于工艺人员的水平，因此磨削参数不能达到最佳。

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。
