Xu Yi said that the United Nations on the prevention of sexually transmitted diseases, made the "ABC" principle. A representative of Abstinency, which means "abstinence", to a total ban may be some difficulty, then step back and to "exercise restraint", in particular young people, we must avoid premature sex. B is Be faithful, which means "loyalty" and replaced by a modern language is to be monogamous or have a fixed partner, not a stranger to have sexual relations. C is the Condom, that is, condoms, this is the last step.

徐克沂表示，联合国对预防性病，提出了"ABC"的原则。A代表Abstinency，意为"禁欲"，要完全禁止可能有些难，那就退一步，做到"节制"，尤其是青少年，一定要避免过早发生性行为。B是Be faithful，意思是"忠诚"，换成现代语言就是要做到一夫一妻制或是有固定的性伴侣，不要和陌生人发生性关系。C就是Condom，即安全套，这是最后一步。

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。

And as experience shows, many have been the conspiracies, but few have been successful; because he who conspires cannot act alone, nor can he take a companion except from those whom he believes to be malcontents, and as soon as you have opened your mind to a malcontent you have given him the material with which to content himself, for by denouncing you he can look for every advantage; so that, seeing the gain from this course to be assured, and seeing the other to be doubtful and full of dangers, he must be a very rare friend, or a thoroughly obstinate enemy of the prince, to keep faith with you.

经验证明：自古以来，阴谋为数很多，而曾经成功者甚少，因为搞阴谋的人都不能够单枪匹马地干。而且，除了那些他认为是心怀不满的人们之外，不能够找到别的人合伙同谋。但是，一旦你向一个不满之徒吐露你的意图，你就给他一个使他可以获得满足的方法，因为他显然可以期待从这里取得各种好处，当他看到：站在这一方面利益是确定的，而站在另一方面则是不确定的并且充满着危险，如果他笃守信义，他就是你的罕有的朋友，否则就是君主的非常顽固不化的敌人。

Nowadays, in the low electron dose condition, the information about 3-4〓 can be recorded on the cryoEM micrograph, and the high-resolution reconstruction using the cryoEM has reached 6. 5-8〓 levels. The reconstruction can reveal the protein α helical and recognise β fold secondary structure. Secondly, it is due to the development in 3D reconstruction method, which can be more efficient to determine the orientation and center parameters. The last but not least, it is also owning to the rapid development in computer science and information technology. Such as, some computational task, which previously must be executed by using super-computer, now can be carried out by personal computer, and at the same time, the network speed and band width of data bus and input/output equipment have increased several times. In addition, the improvement of the high quality graphic displaying is available. All these provide strong support for cryoEM high-resolution reconstruction study.

目前，在低电子剂量的情况下，冷冻电镜照片可以记录到3-4 〓的信息，使用冷冻电子显微镜进行高分辨三维重构工作，已经获得6.5-8〓高分辨率水平的结果，可以分辨出蛋白质的α螺旋、识别出蛋白质的β折叠等蛋白质二级结构；其次是，三维重构算法效能的不断提高，使得对二十面体取向和中心参数计算的可靠性大大提高；再次是，由于计算机和信息技术迅猛发展，例如，以往需要使用大型计算机的计算任务已经可以被一般的个人电脑完成，网络速度、数据总线和硬盘等I／O设备的带宽成倍增长，以及图像显示能力的提高都为冷冻电子显微镜高分辨三维重构技术提供了强有力的支持。

When replacing, firstly, demount the shelters at both ends and the collet of silicon carbide rod, then take out the damaged silicon carbide rod, to be careful when install it, for the silicon carbide rod is easy to be broken.

更换时先卸下两端保护罩与硅碳棒夹头，然后取出已损坏的硅碳棒，由于硅碳棒易断，安装时须小心，两端露炉壳外部分应相等，夹头必须紧固，使之与硅碳棒接触良好。

Now, without entering upon the question, whether the conception of a Law Natural be not exclusively a creation of the Roman jurisconsults, we may lay down that, even on the admission of Grotius himself, the dicta of the Roman jurisprudence as to what parts of known positive law must be taken to be parts of the Law of Nature, are, if not infallible, to be received at all events with the profoundest respect.

现在，无须研究这个问题，即一个"自然法"的概念是否罗马法学专家的一种独有创造，我们可以断言，甚至格罗修斯本人也承认罗马法律学的格言说，有些已知的现实法应该认为是"自然法"的一部分，这个格言纵使不是毫无错误，仍应该受到极端的尊敬而加以接受的。

If the latter possess native sagacity, and a nameless something more- let us call it intuition; if he show no intrusive egotism, nor disagreeably prominent characteristics of his own; if he have the power, which must be born with him, to bring his mind into such affinity with his patient's, that this last shall unawares have spoken what he imagines himself only to have thought; if such revelations be received without tumult, and acknowledged not so often by an uttered sympathy as by silence, an inarticulate breath, and here and there a word, to indicate that all is understood; if to these qualifications of a confidant be joined the advantages afforded by his recognised character as a physician- then, at some inevitable moment, will the soul of the sufferer be dissolved, and flow forth in a dark, but transparent stream, bringing all its mysteries into the daylight.

假如那医生有天生的洞察力，还有难以名状的某种能力——我们姑且称之为直觉吧，假如他没有流露出颐指气使的唯我独尊，他自己又没有鲜明的难以相处的个性，假如他生来就有一种与病人脉脉相通鲍能力，借此使病人丧失警觉，以致自言自语地说出心中所想的事，假如他平静地听到这些表白，只是偶尔用沉默无声的同情，用自然而然的喘息，以及间或的一两个字眼，表示充分的理解，假如在一个可信赖的人的这些品格上加上他那医生身分所提供的有利条件——那么，在某些难以避免的时刻，患者的灵魂便会融解，在一个黑暗而透明的小溪中涓涓向前，把全部隐私带到光天化日之下。

The results show that the influence of accumulation of targets loss must be considered when evaluating operational effectiveness for fake targets antagonizing ARM and their vulnerability should be reduced, their eradiation power should be improved, and reasonable configuration should be adopted when the number of fake targets is increased to improve the operational effectiveness.

On the net collect summed up the following respects, offer text to receive the main page on the site repeatedly, according to website size, more or less can webpage numerary receive all pages repeatedly even; For every join provides a brief introduction, in order to hints this one's duty allows the person that visit is about which on one hand; Exceed in website map and text the mainest crucial term alludes inside join, the help searchs theme of page of join of engine identifying place is about which on one hand; Help engine indexes a few dynamic pages, because a few pages will be of dynamic generation, if not be user behavior is called,will not show come, can put this join on website map, in order to help the dynamic page with engine main index; To make website map attracts the visit of network spider, the descriptive sex statement with go up certain must be written to use this connective keyword to have simple description at the back of join, but the use keyword that cannot transfer, can be just the opposite to what one wished otherwise; Because general spider catchs page of before 3 class only, so website map makes the same score better more, what point to here is logical way, is not physical method.

在网上搜集总结了以下几个方面，提供文本连接到站点上主要的页面，根据网站大小，网页数目的多少甚至可以连接到所有的页面；为每个连接提供一个简短的介绍，用以提示访问者这部分内容是关于哪一方面的；在网站地图和文本超连接里面提及最主要的要害词语，帮助搜索引擎识别所连接页面主题是关于哪一方面的；帮助引擎索引一些动态页面，由于一些页面将是动态产生的，假如不是用户行为调用将不会显示出来，可以将此连接放在网站地图上，以帮助引擎索引重要的动态页面；为了使网站地图吸引网络蜘蛛的访问，一定要在连接后面写上一定的描述性语句并使用此连接的要害词进行简单描述，但不能过渡的使用要害词，否则会适得其反；因为一般蜘蛛只抓前三级页面，所以网站地图越平越好，这里指的是逻辑路径，而不是物理路径。
