Recently, we have detailed a new series of furan-containing teraryl cyclophene derivatives 40a-f and 67. And two keys to syntheses were one-pot furan annulation and the McMurry reaction.

过去我们已成功地利用呋喃成环反应，与McMurry反应合成到一系列的含呋喃之[n.2]环芃烯40a-f与环芃双烯67。

In March 2005, xx I became a research assistant of Professor, I first compare their own programming of foreign journals which discussed the advantages and disadvantages of several types of methods, and then chose a greedy algorithm as a framework for my algorithm, which is inside the I told my colleagues in distress is the expression of the grid structure, and ultimately I use a double arrow pointer and auxiliary pointer perfect solution to a problem, and in practice the efficiency from 72% to 69%.

我的杰出表现受到了学校数据挖掘和数据仓库实验室带头人 xx 教授的注意。2005年三月份，我成了 xx 教授的的研究助理，我先是自己编程比较了国外期刊里面讨论的几类方法的优缺点，然后选择了一个贪婪算法作为我的算法框架，而这里面最困扰我跟同事的问题就是网格结构的表达式，最终我用一个双箭头指针和辅助指针完美地解决了问题，并将其在实践中的效率从72％提高到69％。

If the profile curve has been denoted by a nonuniform rational quadratic B-spline curve, it is very convenient to represent the surface of revolution as a nonuniform rational biquadratic B-spline surface.

只要轮廓曲线用非均匀有理二次B样条曲线来表示，就可相当方便地把旋转曲面表示成非均匀有理双二次B样条曲面。

I once had a friend called Grunwalski. We were sent to Siberia together. When you go to a Siberian work camp, you travel in a cattle car. You roll across icy steppes for days, without seeing a soul. You huddle to keep warm. But it's hard to relieve yourself, to take a shit, you can't do it on the train, and the only time the train stops is to take on water for the locomotive. But Grunwalski was shy, even when we bathed together, he got upset. I used to kid him about it. So, the train stops and everyone jumps out to shit on the tracks. I teased Grunwalski so much, that he went off on his own. The train starts moving, so everyone jumps on, but it waits for nobody. Grunwalski had a problem: he'd gone behind a bush, and was still shitting. So I see him come out from behind the bush, holding up his pants with his hands. He tries to catch up. I hold out my hand, but each time he reaches for it he lets go of his pants and they drop to his ankles. He pulls them up, starts running again, but they fall back down, when he reaches for me.

我曾经有个叫Grunwalski的朋友我们一起被派去西伯利亚，当你去西伯利亚的一个工作营地，你必须乘坐一辆牲口车，你整天穿行在冷冰冰的西伯利亚大草原上，连个鬼都看不见你为了取暖缩成一团这几乎不能让你感到好受些，你不能在火车上方便，唯一的机会是在火车停下来为机车加水的时候才可以可是Grunwalski很害羞，甚至是我们在一起洗澡的时候，他都有些尴尬我过去经常嘲笑他于是，当火车停下来每个人都跳出去在铁轨上方便的时候我狠狠地挖苦Grunwalski，他走开了一个人在那儿火车开动了，每个人都跳上了火车，它不会等人的Grunwalski遇到了麻烦：他已经去了丛林后面，而且还在方便所以我看见他从丛林里出来，用他的双手提着裤子他想赶上火车我伸出手，可是每一次他够到我的手时他的裤子就要掉下来一直掉到他的膝盖上他提起了裤子，重新追上来，但是当他抓住我的时候，裤子又掉了下来
