In the last part of this paper, some numeral test functions were calculated by the software to test the efficiency of the algorithms included, then a reentry vehicle with cruciform flaps were taken as examples to testify the utility of Multi-Objective Optimization Algorithm Library.

在本文的最后，先用几个数值测试函数对方法库中几个产生式算法的性能进行了验证，然后用方法库对带控制舵再入飞行器进行了气动布局和外形优化。

Of course edward and alice werent really related (in forks the story was that all the cullen siblings were adopted by dr. carlisle culler and his wife, esme, both plainly too young to have teenage children), but their skin was precisely the same pale shade, their eyes had the same strange golden tint, with the same deep, bruise-like shadows beneath them.

哦，对了，爱德华和艾丽丝没有血缘关系（库仑家几个孩子的事传遍了整个福克斯城，卡莱尔·库仑医生和他的太太埃斯米年纪轻轻就收养了几个十多岁的孩子有些奇怪），但是，他们的皮肤都同样的苍白无血色，他们的眼睛有都透着同样的金色，眼睛下面有一层相同的深色淤青就像是抹上了一层眼影。

There were ice, snow and supercooled water in cloud, the number concentration of which was more than several per cube decimeter. The cloud frame of ""seeder-feeder"" was distinct.

云中以雪和冰晶为主，有过冷水存在，高层冰晶浓度一般为每升几个到十几个，比秋季层状云多，云系存在分层结构以及"播种-供给"降水机制。

Now this is about more than petty hackers who deface websites. Our ability to bank online, use electronic commerce, and safeguard billions of dollars in intellectual property are all at stake if we cannot rely on the security of our information networks.

这不仅仅是几个小黑客污损几个网站的问题，如果我们的信息网络安全得不到保障，我们的网上银行业务、电子商务活动以及保护亿万美元知识产权的能力就全都岌岌可危。

In chapter two, by using the elements of the matrix we first construct some multiplier factors, then, use the properties of αdiagonally dominant matrix and the techniques of inequalities, we give some new determination conditions for generalized strictly diagonally dominant matrix, these theory have improved some existing results.

在第二章中，利用矩阵某些元素，构造出了几个乘积因子，然后利用α-对角占优矩阵的一些性质，结合放缩不等式的技巧，给出了广义严格对角占优矩阵的几个新的判定条件，改善了已有的某些结果。

This part tries to explore several key issues in Ideological and Political Dialogue Teaching from three aspects; i.'e.; creating dialogue environment; role play of dialogist; design of topics and choice of content. It also points out several misunderstanding and alienation phenomenon that should be avoided when applying Ideological and Political Dialogue Teaching.

Based on the drilling operation of 4 Wells, this article describes the basic characteristic of coalbed methane and technical difficulties in drilling. Some technical keys as borehole quality, fresh Water drilling,fresh water coring, coal-bed methane protection are solved through application of a series of techno1ogical measures such as optimization of rock bit, optimization of drill stem, optimization of drilling parameters and string coring and etc. The experimental performance, especially in fine-grained ...

本文以四口井的施工为例，着重介绍了煤层气井的特点，并指出了钻煤层气井的几个技术难点，通过钻头优选，钻具优选，钻井参数优选，绳索式取心技术等的现场实施和应用，基本解决了井身质量，清水钻井，清水绳索取心，煤层气保护等几个方面的技术难题，文中还介绍了使用中原油田自行设计的中原9508绳索取心工具的取心情况，尤其是在粉煤层地区的取心情况，这将为今后的煤层气开发打下坚实的基础。

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。
