Since 1950 s, the research of numerical method for hyperbolic conservation laws is one of key research directions in computational mathematics. The finite difference method, specially TVD and ENO schemes, for hyperbolic conservation laws are very successful.

双曲型守恒律方程数值计算方法的研究，是二十世纪五十年代以来，计算数学中的一个重要研究方向。

In this paper, we consider hyperbolic conservation laws, and the following work has been done to the finite volume method on unstructured meshes :In preface , we introduce the backupground of the oringe of the finite volume method, and point out the limitation of the finite difference methods and the finite element methods, and import the finite volume method.

本文主要考虑双曲型守恒律方程，对二维非结构三角形网格有限体积方法作了如下工作：介绍了有限体积方法的产生背景，指出了有限差分方法和有限元方法中的特点，对有限体积方法的产生和发展给出了比较详细的分析。

By using a finite term of the optimal sequence, a feedforward and feedback suboptimal control law is obtained.

采用次优控制以避免求解最优控制律的困难不失为一个控制策略[1～3 ] 。

By intercepting finite sum of the optimal control series, a suboptimal control law for the system is obtained.

通过截取最优控制级数的有限和获得原系统的前馈-反馈次优控制律。

In the year she was born, it cost 2 cents to mail a first-class letter, and the Chicago Cubs beat the Detroit Tigers in the World Series.

她在今年诞生，它的成本为2美分邮件一流信小虎击败芝加哥、底特律老虎在世界系列。

I've try the spanish dinner buffet with my friend last week, lots of choice,I like the Iberico ham, very tasty the waiter told me that ham is almost $600/kg 4 time higher than parma ham and the fish soup is very good too, I dislike the tapas bar-too much deep fried food, but my friend like it, I like the hot food more because I can't eat oyster so I took some spanish seafood rice, chicken in the yellow colour soup, don't know what it call, but my friend eat a lots of sashime she like it because there are 8 kinds and the cook slice the fish in front of us, dessert ok la.

呢度对住个伙敌大海景，不过d客都系一家大细多，有少少酒楼感觉；食物方面选择系多，有泰式，印度野，日式，中西式，不过样样都系普通，冇咩特别系出色。。。。有泰式虾饼，印度咖哩鸡/什菜/羊/nann，寿司，鱼生，海鲜，沙律，申烧，烧味，粥，面包。。。etc，野食普通到冇咩可以特别提及；d 寿司切口唔齐，只系青瓜/蛋/蟹柳卷物。。煎三文鱼唔错，甜品款少，蛋糕又唔吸引，雪糕只有3只味。收碟慢，斟水亦慢。。。同价一定有比呢度更好的。。。

Compare with fleshless and pale prince Yul , we would like to see more healthy and mature kim jeong hoon !

比起消瘦苍白的律王子，我们更想看到健康成熟的金桢勋！

For we know that the law is spiritual; but I am fleshy, sold under sin.

7：14 我们原晓得律法是属灵的，但我是属肉的，是已经卖给罪了。

Based on the accurate nonlinear flight dynamics of RLV, the flight manager was established, featuring the flight corridor and effectors health status, which meets the requirement of nominal flight management, guidance/control reconfiguration under off-nominal conditions, and transitioning to an abort mode in response to a more serious situation.

在精确的RLV非线性飞行动力学模型的基础上，综合考虑任务限制条件和舵面完好状况，建立飞行管理模块，实现了标称条件下飞行任务的管理、非标称条件下对制导／控制律的重构以及严重事故时任务中断策略的实施。

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。
