摘 要 在这篇文章里，我们用双线性对构造了一种无证书的环签名方案，并证明它是无条件匿名的，且在随机预言模型中，计算性D iffie2Hellman 问题是难解的，我们方案在适应性选择消息攻击下是存在性不可伪造的，它的安全性比在基于身份的公钥密码体制下高。

So, When the power system is in transient, the sliding mode control rule is chose directly to make transient component decrease quickly, and when the power system is in stability, the direct current control method based on voltage space vector method is imported to make the error current reduce to zero by inches and avoid surge.

为此，当系统处于暂态时，论文直接选择滑模控制率使暂态分量迅速减小，当系统处于稳态时，引入基于电压空间矢量的直接电流控制方法，使误差电流趋于0缓慢变化，在有效补偿系统无功的同时，提高了系统的动态特性，并大大降低了系统振荡的可能性。

But using infrared CCD, which has little scattering light, strong penetration ability, can improve image quality greatly. This paper analyzes the effects on surveillance by Rayleigh scattering, Mie scattering and unselective scattering theoretically. In addition it discusses the relation between transmission coefficient, reflection coefficient and wavelength of infrared CCD.

而采用散射光小，穿透能力强的红外CCD，则可以显著改善图象质量，从理论上分析了Rayleigh散射，Mie散射，无选择散射对监测的影响，讨论了红外波段CCD的反射系数、透射系数与波长的关系。

On the basis of the modification theory, relative modification concept of cycloidal gear pair and the appraisal index of the initial backlash are built to solve the problem that cycloidal gear works unsmoothly in pin wheel of the full-hydrostatic steering control units. The major goal of modification is a uniformity of initial backlash, so equidistance modification that has good effect on improving quality of fluid cycloidal pair is chosen.

为解决全液压转向器转子转动不灵活的问题，在分析现有摆线针轮啮合副齿廓修形理论基础上，建立摆线副修形的相对性概念和间隙分布评价指标，提出无系杆摆线副修形的主要目标应使初始间隙分布均匀，选择的修形方式为等距修形。

The basic signification of adverse selection is that the markets collocating function will be inefficient because of the behavior of the traders when the information is asymmetric.

逆向选择的基本含义是指在市场信息不对称的条件下，经济人的博弈过程会导致市场资源配置的无效率。

For the same price, Shambler Thralls are more fragile but mindless and can leave the seas, which makes them a better choice in general (i.e. not against Atlantis).

在同样的价格中，Shambler奴隶更脆弱（可怜的护甲，非常弱的魔法防御）单却是无脑的并能够离开大海，这使得他们在大多数情况下是个更好的选择（当然，不是对Atlantis时）。

Although paper has to be fed and held down manually, arbitrary hold-down pressure against paper is thus available to avoid the disadvantage resulting from improper hold-down pressure The paper-cutting blade holder is driven by a motor, but it can also be operated by means of a handle to suit the needs of the location where power supply is not yet available.

本机的送纸与压纸需要手动，但压纸时，压力可任意选择，故可避免压纸的压力不适所引起的弊病。刀座切纸是由电动机驱动，但也可用手柄摇动，可适用在无电源的状态下下使用。

Love is usually poeticized, decorated with roses, nightingales; we Russians decorate our loves with these momentous questions, and select the most uninteresting of them, too.

我们俄国人却用些重大的问题来装饰爱情，且选择了其中最无趣的部分。在莫斯科读书时，我有一位与我一起生活的朋友，一位迷人的女士，每次我把她抱在怀里，她就在想我这是允许她帮我料理一个月的家务以及一磅牛肉多少钱。

In this paper, an unsupervised learning mechanism based on ant colony pheromone is designed for the function optimization problem.

为了克服Memetic算法的这一缺点，针对函数优化问题提出了一种基于蚁群信息素的无指导的学习机制，并在此基础之上构造了基于信息素模因的克隆选择算法。

Salad - Yes, it might be rabbit food, but a good leafy salad with croutons, vegetables, fruits, chicken, and a low-fat or non-fat dressing is a great way to end your day.

沙拉-是的，这可能是兔子的食物，但一个好的蒜香绿叶沙拉，蔬菜，水果，鸡肉，加上低脂肪或无脂肪的调料是结束一天的好选择。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
