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

When boarding in a hotel, I had always to put one or two bucks on the pillow for the charwoman every morning; when dining in a restaurant, another 10%—20% of the check for the waiter; even when taking a taxi, I had to pay extra money and ironically, many drivers run their own business.

说是小费，数目对于我这样的中国土鳖来说可不算小，住旅馆，每天早上要在枕头放一两个美元，给打扫房间的大姐；吃饭要把餐费的 10%-20%给服务员；甚至连坐出租车也要额外给小费，其实很多出租车司机自己都是老板。

When scaled factor circulant matrices are nonsingular, we can find the single solution of the scaled factor circulant matrix equation; When scaled factor circulant matrices are singular, we can find the special as well as the general solution of the scaled factor circulant matrix equation; There is only an error of approximation when the fast algorithm is implemented on computers, and only the elements in the first row of the scaled factor circulant matrix and the constants in the diagonal matrix are needed by the fast algorithm.

当鳞状因子循环矩阵非奇异时，该快速算法求出线性方程组的唯一解；当鳞状因子循环矩阵奇异时，该快速算法求出线性方程组的特解与通解。该快速算法仅用到鳞状因子循环矩阵的第一行元素及对角矩阵中的对角上的常数进行计算。在计算机上实现时只有舍入误差。

Finally it analyzes the feasibility that using hydromechanics to analyze traffic flow by contrasting various characters between traffic flow and fluid flow. It analyzes influence of road alignment to basic expressway segment capacity by hydromechanics, and obtains viscous resistance and viscous movement differential equation when the vehicle drives on circular curve segment of expressway. And it infers that viscous resistance is correlated with sideway force coefficient, slope of crown and radius of circular curve. Radius of circular curve, sideway force coefficient and slope of crown are bigger, viscous resistance is smaller, the influence to capacity is smaller when the vehicle is running on nearside lane of circular curve; but radius of circular curve and sideway force coefficient are bigger, slope of crown is smaller, viscous resistance is smaller, the influence to capacity is smaller when the vehicle is running on fast lane of circular curve.

最后通过对比交通流与流体流的相似性，运用流体力学分析了道路线形对快速路基本路段通行能力的影响，求出了车辆在曲线路段的粘性阻力，建立了车辆在曲线路段的粘性运动微分方程，并由此推知，粘性阻力与横向力系数、路拱横坡度和圆曲线半径都有关系，当车辆在圆曲线外侧车道上行驶时，圆曲线半径、横向力系数和路拱横坡度越大，粘性阻力就越小，对道路的通行能力影响就越小；而当车辆在圆曲线内侧车道上行驶时，圆曲线半径和横向力系数越大，路拱横坡度越小，粘性阻力就越小，对道路的通行能力影响就越小。

The combustion is not the low NOx combustion when is less than the limited least value.
