VIII. All French territory should be freed and the invaded portions restored, and the wrong done to France by Prussia in 1871 in the matter of Alsace-Lorraine, which has unsettled the peace of the world for nearly fifty years, should be righted, in order that peace may once more be made secure in the interest of all.

全世界应同意，在比利时的占领军必须撤退，其领土必须恢复，不得企图限制她应与其它自由国家同样享有的主权。其它任何一种行动均不能起这样的作用，因此唯有这样做才能使世界各国对于它们为了协调彼此关系而建立和确定的法律，恢复信心。如果没有此项治疗创伤的行动，国际法的整个体系与效力，将永远受损。

Want those who improve software to be able to safeguard gender, alterability, design low coupling, tall cohesion with respect to what must let us, also must accomplish duty drive to design .

要提高软件的可维护性、可变更性，就必须让我们的设计低耦合、高内聚，也就必须做到职责驱动设计。

If we would employ it, we must Americanize it, and that not formally, in language merely, but radically, in thought, principle, and aim as well.

如果我们要应用这种科学，我们必须使之美国化，不只是从形式上或仅仅从语言上美国化，而是必须在思想、原则和目标方面从根本上加以美国化。

We must be wary of Ancona, we must also beat the small sides if we want the Scudetto.

我们必须警惕安科纳，如果我们希望赢得联赛冠军，我们还必须击败小球队。

As a result, if the iridescence is produced by thin-film interference, not only the thickness of lamellar structure must be defined within a certain nanometer, but also the refractive index need to be different between lamellar structure. In other words, the chemical composition, refractive index and thickness of exsolution lamellae need form to trinity, such as labradorite, albite, andradite and orthoamphibole. If the iridescent color is produced by grating-diffraction, the lamellar structure just needs to be arrayed regularly, the spacing of the edges of lamellar structure needs to be regular and narrow, but not necessarily within the range of the wavelength of visible light, such as shell of abalone, pearl and opal.

薄膜干涉式晕彩不仅要求宝石内部结构层的厚度必须在一定的纳米范围内，而且结构层内部的折射率也必须有所差别，也即，当结构层由两相组分出溶而成，其化学成分、折射率和结构层厚度形成三位一体时，符合薄膜干涉式晕彩，如拉长石、钠长石、石榴石和角闪石；而光栅式衍射晕彩则仅要求结构层排列规则，边缘狭窄但不需要窄到可见光波长范围内，能使入射光的振幅或位相，或两者同时产生周期性空间调制的结构即可，如鲍贝壳、珍珠和欧泊。

You'll have to know how to scuba dive to reach your room, and guests without the mandatory certification must take a course at the hotel. Once you've reached the lodge, which sleeps up to six, you'll be close to angelfish, anemones, barracuda, oysters, and other creatures — each room is equipped with a 42-inch window, so you don't need to be suited up to keep an eye on the neighborhood.

你必须懂得如何潜水抵达你的房间，客人们没有义务保证必须按一定的航道到达酒店，一旦你抵达酒店就可以睡到六点钟，你可以接近扁鲨、海葵、梭鱼、牡砺和其他生物——每间房都装备了42英寸视窗，所以你没有必要穿上衣服留意你的邻居。

I have to admit that somehow I have a special feeling with Poland,on issues about that country,I often bias for her.and in this film,as someone has pointed out,there is somewhat an anti-communism sentiment,even the director himself has said in a speech:...

我必须的承认我对波兰有一种特殊的感情，在关于波兰的问题上，我总是偏袒这个国家。我也必须告诉你们，有人指出 Andrzej 的这个电影有些反共的色彩，就连 Andrzej 本人也在一次演讲中说过：。。。

We must beware of the pitfall of antiquarianism, and must remember that for our purposes our only interest in the past is for the light it throws upon the present.

我们必须警惕好古主义的陷阱，且必须记住，对我们的目的而言，我们对过去的兴趣只是它照耀现代的光芒。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
