We hung about the stadium, we've got no place to stay We hung about the tenderloin and tenderly you tell About the saddest book you ever read that always makes you cry The statue's crying too and well he may I love you I've a drowning grip on your adoring face I love you my responsibility has found a place Beside you and strong warnings in the guise of gentle words Come wave upon me from the family wider net absurd "You'll take care of her, I know it, you will do a better job" Maybe, but not what she deserves Elope with me Miss Private and we'll drink ourselves awake We'll taste the coffee houses and award certificates A privy seal to keep the feel of 1960 style We'll comment on the decor and we'll help the passer by And at dusk when work is over we'll continue the debate In a borrowed bedroom virginal and spare The catcher hits for .318 and catches every day The pitcher puts religion first and rests on holidays He goes into cathedrals and lies prostrate on the floor He knows the drink affects his speed he's praying for a doorway Back into the life he wants and the confession of the bench Life outside the diamond is a wrench I wish that you were here with me to pass the dull weekend I know it wouldn't come to love, my heroine pretend A lady stepping from the songs we love until this day You'd settle for an epitaph like "Walk Away, Renee" The sun upon the roof in winter will draw you out like a flower Meet you at the statue in an hour Meet you at the statue in an hour

我们红约大球场，我们已经准备好没有住宿地点我们红关于tenderloin和温柔，你告诉关于最悲惨的书，你读总是让你哭雕像的哭声太以及他可能我爱你我已经一溺水掌握在您的崇拜面对我爱你，我有责任找到一个地方旁边的你和强烈的警告，假借温柔的话来波后，把我从更广泛的家庭净荒谬"你可以照顾她，我知道它，你会做的更好"也许，但不是什么值得她 elope与我错过私人，我们会喝自己清醒我们将品尝到咖啡的房屋和颁授证书 1枢密院密封，以保持觉得1960年的作风我们会发表评论装潢和我们将帮助途由和黄昏时的工作是超过我们将继续辩论在借来的卧室处女和备件捕手安打为0.318和捕捞的渔获，每一天投手把宗教首先在于对假期他进入大教堂和谎言前列腺在地板上他知道酒后影响他的速度，他的祈祷一大门口回到生活，他希望和认罪的板凳生活以外的钻石是一个扳手我希望你在这里跟我通过平淡的周末我知道它不会来的爱，我的女主人公假装一位加强从我们热爱的歌曲，直到这一天您想要解决为墓志铭一样，"走开，蕾妮"太阳后，屋顶在冬季将以此为你喜欢的花满足你的雕像在一个小时满足你的雕像在一个小时

This approach has the advantage that the contact discontinuity in each local wave pattern is always fixed with speed zero and the rarefaction waves and shock waves are located on either side.

这种方法的优点是每个局部波形中的接触间断速度都为零，并且疏散波和激波分别位于时间轴的两侧。

As an often used physical model with good theoretical and practical values, StreeterPhelps model has been widely used to study water quality. However, in some special water areas the utilitization of StreeterPhelps model has some limitation as confirming reaeration coefficient often comes from tests in rivers with fast water flow speed with no consideration of wave effects. Furthermore, in practical research in Three Gorges Reservoir, the changing rule of COD appears abnormally. In some water areas far from pollution source, the value of COD changes with time, but does not follow the exponential attenuation rule. This phenomenon can not be explained by former modified StreeterPhelps model.

StreeterPhelps模型是目前进行河流水质研究常用的物理模型，具有良好的理论和实用价值，然而在某些特定水域，该模型的应用受到限制，主要原因是复氧系数的取定多在水流速度较大情况下得到的，而未考虑水面波动对复氧系数的影响，另外，在实际研究过程中发现三峡库区COD变化的规律出现异常：在离排污口相当远的水域，COD随时间变化趋势并不是指数衰减，而是在某个常值附近微小摆动，以往很多修正过的StreeterPhelps模型都无法解释这个现象。

Refraction is the change in direction of a wave due to a change in its speed .

折射是一种改变波的方向，因为它改变了它的速度。

High precision format, unstructured dynamic mesh with a large displacement and multi-species gas flows were computationally expensive, the problem of resourceless and inefficient of single computer appeared. Parallel arithmetic based on PC-Cluster system for the oblique detonation wave flow and the muzzle flow include high speed projectile were discussed. The results proved that the rationality of parallel arithmetic provided a new method to simulate the complex chemical reaction flows. The present code represents a validated, efficient and versatile tool developed for the simulation of hypersonic multi-species chemical non-equilibrium flows.
