Von Neumann was particularly interested in seeing if he could develop optimal strategies for these kinds of mutual games, because at first glance they seemed almost insolvable in theory.

冯诺依曼最感兴趣的是想看看自己能否给这种互动游戏找出最理想的策略，因为乍一看来，它们在理论上几乎是无解的。

The classical principal component analysis is one of the most effective feature extraction methods. PCA essentially gives the optimal representation in a minimum of mean square sense, so it is usually used to minify the dimension of high dimensional image pattern modes.

传统的主分量分析方法是最为经典的图像特征抽取方法之一，由于其本质上是在最小均方差意义下给出了模式样本的最优表示，所以它通常被作为对高维图像模式进行降维的一种常用方法。

In just three weeks of work on federal land near Hanksville, Utah, paleontologists say they unearthed at least two meat-eating dinosaurs, a probable Stegosaurus, and four sauropods—long necked, long-tailed plant-eaters that could reach 130 feet (40 meters) long, making them the largest animals ever to have walked the Earth.

在犹他州汉克斯维尔附近的联邦国土上仅仅工作了3周，古生物学家们就声称他们挖掘到了至少2只食肉恐龙——很可能是剑龙，和4只雷龙——长达130英寸（4米），曾经漫步在地球上的最大的长脖子、长尾巴素食者。

Phthalic Acid Esters have been extensive used in industry,and become one of the most widely pollutants in environment.PAEs were detected in most environmental medium such as air,water and sediment nowadays.

由于在工业上的广泛应用，邻苯二甲酸酯类化合物已成为地球上最普遍存在的环境污染物之一，目前在大气、水体、土壤中均可检测到。

In aim at the complicity and high-dimensional state-space for the controlled system, it simplifies the calculation of geometric polytope by optimize with ellipsoidal approximate techniques, and the robust control effectiveness near to the optimal.

本论文所提示的基于几何理论的约束非线性控制算法是建立在最大输出允许集合的基础上，运用状态空间的有界子集表达鲁棒时优离散时间控制问题的价值函数，通过逆序计算该价值函数的水平集合，求得其所需的控制量，针对被控系统的复杂性及高维状态空间问题，运用椭球近似技术予以优化，使得几何多面体的计算得以简化，且鲁棒控制效果接近最优。

Strip limit minimum rollable gauge and minimum rollable gauge considering productivity are analyzed and derived using new rolling pressure model, work roll surface temperature rise formulae is derived on the basis of mill stand thermal balance. The affecting factors of work roll surface temperature and the influences on the choice of roll size are discussed.

本文从轧机结构设计、力能参数计算、强度设计计算等方面综合论述了辊系参数设计计算的基本理论，在理论上提出了采用考虑粘着摩擦的混合摩擦模型和考虑轧件的弹性变形计算冷轧薄板轧制压力的方法，推导并以冷轧机实测轧制压力验证了轧制压力新模型；应用新的轧制压力模型分析并推导了轧件极限最小可轧厚度和考虑生产率的最小可轧厚度公式；根据工作机座热量平衡原理推导了工作辊温升公式，分析了工作辊温度的影响因素，研究了工作辊温升对轧辊参数选择的影响。

The total instantaneous blockage accident study progress was summarized in the paper. The most important SCARABEE-N in-pile tests in TIB fields were reviewed, also various out-of pile backup tests. The SCARABEE BE+ group and APL group, which were directly linked to TIB scenario, were compared for the different test conditions and phenomena. Many analysis models and computer codes developed in parallel with SCARABEE program were presented, followed by using SCARABEE results for code verification and engineering practice.

本文总结了TIB研究在国际上的进展，综述了TIB研究领域最重要的SCARABEE-N实验和各种相关堆外实验，并将与TIB研究关系最紧密的BE+组和APL组实验的条件、进程进行了对比，同时介绍了与SARABEE计划同步开发的各种分析模型和程序，以及将SCARABEE实验成果用于其他程序的验证工作和应用情况。

Alaska is the most earthquake-prone state and one of the most seismically active regions in the world.

阿拉斯加是最地震多发国家之一，地震最活跃的地区，在世界上。

Yesterday afternoon ,i had come across him .in my mind i had nearly forgotten the hated person.but why let me come across him again.he sent the message to me by QQ.and ask some strage questions.it made me very puzzle.i think this year i am very unluck that let me know the two persons.and all were so failed.

中午跟姐在QQ上聊了会儿，他跟我说姐夫要到新疆去办厂如果发展的好的话连同姐一起居住那。当她跟我说这些的时候我竟然哭了。不知怎么的现在的我既然变的那么脆弱。以前总认为自己有多么的坚强。因为爸妈都在外面做生意。所以跟他们最多也只是电话上相互的照面寒暄。

But I do ask that you use your education to pursue only the worthiest of goals; goals that can contribute to betterment of the lives of pthers; and goals that give you personal satisfaction because of their contribution to the society we live in....

但我恳切的请求你们把学到的最有价值的只是用在最值得追求的目标上；致力于给他人创造更美好的生活；这样你才会因为对我们生活的社会做出贡献而令自己感到满意。。。。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
