不能变的

On the establishment of shielding immune cells avoid HIV viral antigens identified protein adsorption and the establishment of "biological trap" induce HIV models Summary : HIV is the human immunodeficiency virus caused AIDS virus, AIDS is not currently be fully human control, AIDS vaccine is being developed, but because the virus genetic diversity potential to change the topic of the complexity of this ban from the incidence of HIV spread T4 cells in the mechanisms by, proposed changes T4 lymphocyte surface protein CD4 receptors structure as to avoid HIV adsorption, and the establishment of "biological trap" booby HIV idea to try to turn on AIDS treatment to the conversion of protein structure and function, as well as synthetic direction.

提要：HIV即人类免疫缺陷病毒是引起AIDS的病毒，目前爱滋病还不能被人类完全控制，AIDS的疫苗也正在研制中，但是由于病毒多样性的遗传潜能，使这一课题变的很复杂，本文试从HIV侵染T4细胞导致发病的机理入手，提出改变T4淋巴细胞表面CD4受体蛋白构象以避免HIV吸附，并设置"生物陷阱"诱杀HIV的构想，试图把对爱滋病的治疗引向对蛋白质结构与功能转化以及合成的方向。

With the development of medical science, timely diagnosis of bleeding and thrombotic diseases, to observe the efficacy of anticoagulant drug dose, such as analysis has become increasingly urgent, and the traditional manual methods and a single check has been solidified as far from enough to meet clinical requirements, The emergence of automatic coagulometer and applications, making the project to check hemostasis and thrombosis has become simple, accurate, reliable, great to meet clinical needs.

随着医学科学的发展，及时诊断出血、血栓性疾病，观察疗效，分析抗凝药物剂量等显得越来越迫切，而传统的手工方法和单一的凝固定性检查已经远远不能满足临床要求，全自动血凝仪的出现和应用，使得止血和血栓项目检查变得简便、准确、可靠、极大地满足了临床诊疗的需要。

The results showed:(1)the factors which influence causal judgment were that the cause was the real cause or stimulative,the familiarity of the cause,and the covariation degree of causes with outcomes;(2)the character of questions didn't influence causal judgment;(3)causal judgment...

结果发现：(1)影响因果判断的因素有：事件原因与促进条件的性质差异，原因的熟悉度，原因和结果的共变程度；(2)问题抽象性对因果判断没有影响；(3)概率对照模型和因果模型理论在一定的情况下适用，但是都不能解释所有的情况。

Some small merchants sell the vegetables fruit fish flesh around our school, they even hawk attract passer-by's attention, just like we know, has a peaceful environment to us is extremely important, but we hear their noise in the classroom, but cannot hear teacher's sound clearly, they cause the street to change more importantly are unable to withstand dirtily, stink to high heaven, road congestion, therefore I write a letter for you in order to enable the condition to obtain the change for the better!

一些小商贩在我们学校周围卖蔬菜水果鱼肉，他们甚至叫卖来吸引路人的注意，正如我们所知，对我们来说有一个安静的环境是非常重要的，但我们在教室里听到他们的噪声，而不能清楚听见老师的声音，更重要的是他们使街道变的肮脏不堪，臭气熏天，道路拥挤，因此我写信给你为了使状况得到好转！ the end 谢谢！辛苦了

Head in the disk rotational speed and the speed of operation remain unchanged, the same time, head-to-disk can visit some of the region.

在磁盘转速和磁头的操作速度不变的情况下，相同的时间内磁头所能访问到磁盘的区域是一定的。

In the precision detection of a millimeter wave, the encounter of the detector and the objects can not be forecasted totally because of a lot of noise and disturbance existing in the complex battlefield, it will cause fantasticality and distortion of the echo retaked by the detector, and the stably of the echo become bad, as a result, it will reflect the result of the detection, so it is necessary to filter the echo retaked by detector.

在弹载毫米波精确探测系统中，由于复杂多变的战场环境中存在大量的干扰及噪声，探测器与目标的交会姿态不能完全预测，造成探测器获取目标回波产生奇异和变形，回波特征的稳定性变差，从而影响了目标的探测和识别，因此对探测器的回波进行有效的滤波处理是十分必要的。

Or for the health conscious, there are a lots of low-fat, flavorful products to grill – including soy burgers. Low-fat meats, like flank steak, are economical and marinated to tenderize (that's why it's cheaper – you can't just throw it on the grill like a high fat meat, to get a tender product).

低脂的肉制品，例如经济实惠的牛肋，通常是经过腌泡而变的很软（这也就是为什么它很便宜—你决不能像高脂肉类那样把它往烤架上一扔，这样烤出来的肉是不可能嫩的）。

So I take the phone pad and I put it right here, I'd take the business card, I'd put it right here, and I'm matching the shape of the squiggles on the card to the shape of the squiggles on the phone pad.

我只是想逃离。由于我不能明确自己身体的范围，我又感到身体变大了、舒展开来了，就像一个从瓶子里跑出来的神怪，而我的灵魂则如一条鲸鱼，漫游于寂静的极乐世界的海洋。

This article analyses the actual reality of network security and briefly intruduces a few of aggressive measures which threaten the safety of network. From these we can see, the passive ways such as firewall and anti-virus software to combat network attack can not meet the increasingly needs of network accessing .As a result, an intrusion detection system must be established to differentiate between the legal accessing and inbreaking attack. That is intrusion detection.

本文首先分析了目前的网络安全现状，简单介绍了几种威胁网络安全的攻击手段，从中可以看出通过防火墙和杀毒工具等软件，被动地防御网络攻击已经不能满足日益增加的网络访问量了，因此必须变被动为主动，对到达的网络访问内容进行审核，来判断是合法的访问还是入侵攻击，这种审核就是入侵检测。

We doodlers, fidgeters and whisperers always get the same jokey, passive-aggressive line from the authority figure at the front of the room:"I'm sorry, are we bothering you?" How droll.
