一滑

At last, seeing the ship still bore on her course, and was now swiftly drawing out of earshot, one of them - I know not which it was - leapt to his feet with a hoarse cry, whipped his musket to his shoulder, and sent a shot whistling over Silvers head and through the mainsail.

最后，他们看船还不停下来，而且愈走愈远，眼看着听不到喊声了。其中一个--我叫不准是哪一个--便大叫一声跳起来举起滑膛枪就放。一颗子弹嗖的一声从西尔弗头顶上飞过，把主帆打了个窟窿。

Based on this, a new WENO difference scheme which based on Dispersion-Relation-Preserving relation is developed, and representative test cases with this scheme for computational aeroacoustics problems has been implemented and compared in order to test capability of wave capturing; In addition, WENO schemes generally do not converge at high order in the presence of contact discontinuity of Euler equations, so a conservative front tracking technique coupling WENO schemes and Level Set method to simulate the translating density profile is presented here, and numerical simulation with this technique for representative test case has been implemented and results show the desired accuracy.

本文研究了高阶精度加权基本无振荡格式及其在双曲守恒律方程中的应用，在此基础上作了两个方面的工作：一是针对高频声波问题构造出一种基于保色散关系的WENO有限差分格式，并对计算气动声学问题的代表性算例进行了大量数值实验，比较了该格式捕捉波数的能力；另外，针对高阶WENO格式在处理Euler方程的接触间断时精度有所降低的问题，研究了利用界面追踪技术Level Set方法和高阶激波捕捉WENO格式相结合的一种守恒追踪方法，并且给出有代表性的密度滑移面问题的算例，得到一致高阶精度的数值模拟结果。

But sometimes Squaw Walden had her revenge, and a hired man, walking behind his team, slipped through a crack in the ground down toward Tartarus, and he who was so brave before suddenly became but the ninth part of a man, almost gave up his animal heat, and was glad to take refuge in my house, and acknowledged that there was some virtue in a stove; or sometimes the frozen soil took a piece of steel out of a plowshare, or a plow got set in the furrow and had to be cut out.

有时候，瓦尔登这印第安女子复仇了，一个雇工，走在队伍后面的，不留神滑入了地上一条通到冥府去的裂缝中，于是刚才还勇敢无比的人物只剩了九分之一的生命，他的动物的体温几乎全部消失了，能够躲入我的木屋中，算是他的运气，他不能不承认火炉之中确有美德；有时候，那冰冻的土地把犁头的一只钢齿折断了；有时，犁陷在犁沟中了，不得不把冰挖破才能取出来。

All summer I wandered the fields that were thickening every morning, every rainfall, with weeds and blossoms, with the long loops of the shimmering, and the extravagant- pale as flames they rose and fell back, replete and beautiful- that was all there was- and I too once or twice, at least, felt myself rising, my boots touching suddenly the tops of the weeds, the blue and silky air- listen, passion did it, called me forth, addled me, stripped me clean then covered me with the cloth of happiness- I think there is no other prize, only rapture the gleaming, rapture the illogical the weightless- whether it be for the perfect shapeliness of something you love- like an old German song- or of someone- or the dark floss of the earth itself, heavy and electric.

整个夏天，我漫步于田野，在每个清晨，每一场雨中，田野变得深邃，充满种子和花，以及闪烁不定的耀眼的光环——如同苍白的火焰，它们升起又熄灭，丰盈而美——这就是田野的全部——而我至少有一两次，感到自己飞起来了，我的鞋子突然碰到种子的顶端，丝绸一般柔滑的蓝色空气——听，它热情地召唤我，使我迷茫，剥去我的外壳，再为我穿上欢乐的衣裳——我不再需要什么，只是沉迷于这闪亮的一刻，沉迷于这不合逻辑的失重——它是否是你所爱之物的完美形式——属于一首古老的德国歌曲——或者某个人——或者就是地球自身的黑色丝线，沉重，带电。

Just like Friday I desperately struggled to seat my axe in the crux tin-opener 胸带?. I screamed to Joe to expect a fall and released my left axe, cutting loose onto one arm. The axe slid and jerked a centimeter. My heart missed a beat and the jolt nearly made me fall, my hand sliding down the upside-down axe to the head and rolling onto three fingers.

后来爬到 crux时，在爬到后来的他用2.5小时领攀了那段路线，我大声的呼叫 Joe，希望他往下降一点，帮我把挂在左面的冰斧取出来，试图两手轮流砍冰前进，但我好像没有把冰斧固定住，突然滑动了大约一厘米，我一紧张，斧子从手里滑了下来，差点碰到我的头，刹那间我用三个手指头再次抓住它，就在这一瞬间，我整个身体差点坠落下去，心也一下子提到了嗓子眼，砰砰直跳。

The main structure uses the design of the ellipse trochoid of the 4 bar strider. We made the ellipse trochoid to be the optimum state for reaching the simulation effect when people are running. Besides, the design can switch to be a new six-bar strider. It uses a link bar to bind the axis pillar and the pedal also made the pedal slide free to reach the sport effect.

At last, all related problems due to ship type and towing speed influencing the quality of captured images and results were discussed. A ship model with V-shape bottom and protruding keel might cause some disadvantages for PIV measurements. The use of longer laser light ducts extending deeper is a possible solution. A ship model with light yellow paint will cause the unproportionate of light and will cause white background on captured images. It is suggested to re-paint the ship model in black or dark colors to solve this problem. In high-speed test conditions, a ship model's bow waves entrain large amount of air bubbles into water and those bubbles will block the view of camera causing some random black spots in the images. Thus, it is necessary to remove the useless black spot data and repeat the same test condition if statistics requires enough number of images.

本文讨论建立此系统之技术及实验方法，设备的架置方式和配置为一可调性调整之开放式架构，质点施放方法以一自制的施放架於实验前先布置於测试段中，并制定一实验流程规范，再分别针对实验所得滑航型及排水量型船模的流线方向及切流线方向各不同位置及船速之速度进行流场分析；实验结果发现不同船型会造成不同的实验困难：船形上突起之龙骨及V形船底会遮住照明光线，可利用较深之导管调整光页角度改善；而浅色船模表面会造成光线的不均匀，可以更改船模涂装颜色改善；高速实验的气泡会不定点的遮住光线，须先除去无资料区域并使用更多资料组数来改善。
