Provable Security is a formal method for proving the security of cryptographic schemes, in which the difficulty of breaking a particular scheme is formally related to that of solving a widely believed computational hard problem. Provable security has already become an important theme of theoretical researches in modern cryptography. This dissertation investigates the provable security of public-key encryptions and hybrid encryptions of asymmetric and symmetric encryptions. This includes the various formal security notions and the constructions can be proved to achieve them. Among the constructions, hybrid encryptions are themselves an important way to obtain public-key encryption schemes with chosen ciphertext security. The main results are as follows:(1) The one-wayness of the trapdoor one-way function in NTRU depends on the randomness of the session key, which is different from previous ones. Based on this observation, a new kind of trapdoor one-way function, trapdoor one-way functions with an auxiliary random variable is proposed.

可证明安全性是一种证明密码学方案安全性的形式化方法，它将密码学方案的安全性归约为公认的计算难题，已成为现代密码学领域中理论工作的主线，本文主要研究公钥加密与单双钥混合加密的可证明安全性，这包括它们的各种形式化安全性定义以及达到这些安全性定义的方案构造，而单双钥混合加密本身也是一种构造选择密文安全公钥加密的重要方法，本文得到的主要结果如下：(1)在研究NTRU公钥加密的特殊性基础上，对于公钥加密的陷门单向函数加密模型进行了扩展，提出了具有辅助陷门单向函数的概念，并将其扩展到多元的情况，讨论了可能的密码学用途。

In the taller of high-rise buildings, the system is likely to be found inappropriate for a stand-alone system, this because of the difficulty in mobilizing sufficient stiffness under lateral forces.

在高的高层建筑，该系统很可能会发现不合适的一个独立的系统，这个，因为难以调动足够的刚度下的侧向力。

Here, gentlemen, is our difficulty: When we plead our cause before the law-makers and savants of the republic, they can not take in the idea that men and women are alike; and so long as the mass rest in this delusion, the public mind will not be so much startled by the revelations made of the injustice and degradation of woman's position as by the fact that she should at length wake up to a sense of it....

先生，这就是我们困难之所在。当我们面对共和国的议员和学者，爲我们的事业辩护队他们无法接受男人和女人是相像的观点。只要这些人都处于这种错觉之中，那么公共舆论对于所揭示出的妇女地位的不公正和低下所表示的惊讶，将比不上对妇女终于觉醒、并且意识到这一不公正事实所表示出的惊讶。

The membrane isolation pumps is one kind of hydromass transportation hydraulic system,can reduce the cartage expense greatly,but indirectly brings the huge social efficiency,safe reliable,the work rate is high,may not stop nearly carries on the whole year to transport,does not have the material to lose nearly,the easy automatic control,to be advantageous for the maintenance management The hydraulic pressure diaphragm pump is one kind of fill domestic diaphragm pump which we develops in high-pressured,the small curr ent capacity pulp transportation aspect blank pumps plants,it and the common diaphragm pump main difference is:Has substituted for the crank connecting rod,the reduction gear using the hydraulic pump and so on aseries of equipments direct drive piston motion,this causes its structure is greatly the simplification,the cost drops greatly;When at the same time also requests the piston the commutation confidential assurance extremely accurately,but must realize this point theoretically and all has the very great difficulty in fact.

膜隔离泵就是一种浆体输送的液压系统，能大大降低运输费用，可间接带来巨大的社会效益，安全可靠，作业率高，几乎可不停地进行全年输送，几乎没有物料损耗，易于自动控制，便于维护管理。液压隔膜泵是我们开发的一种填补国内隔膜泵在高压、小流量矿浆输送方面空白的泵种，它与一般的主要区别是：利用液压泵取代了曲柄连杆、减速器等一系列装置直接驱动活塞运动，这使其结构大为简化，成本大大下降；但同时也要求活塞的换向时机要把握得非常准确，而要实现这一点理论上和实际上都存在很大难度。

Although the IPv4 has already obtained to make the person is hard to place the success of the letter, along with lately- apply flow out continuously now, the traditional IPv4 agreement is hard have already supported an Internet to extend further with the characteristic of the new business, among them the most attractive with the most remarkable of can improve it to be placed in in its address space of size, expand a sex problem,manage a problem and choose road in addition a difficulty,service of the consignation and the safety problem of the improvement and the service quality characteristic is also convex appear, so the IPv6 transitions become no time for waiting now.

虽然IPv4已经取得了令人难以置信的成功，但随着新应用的不断涌现，传统的IPv4协议已经难以支持互联网的进一步扩张和新业务的特性，其中最显眼和最值得注意的可改进之处在于其地址空间的大小，除此之外扩展性问题、管理问题、选路困难、服务的改进和服务质量特性的交付以及安全性问题也凸现出来，因此现IPv6过渡变得迫不及待了。

Any general meeting declaring a dividend or bonus may direct payment of such dividend or bonus wholly or partly by the distribution of specific assets and in particular of paid－up shares,debentures or debenture stock of any other company or in any one or more of such ways and the directors shall give effect to such resolution,and where any difficulty arises in regard to such distribution,the directors may settle the same as they think expedient,and fix the value for distribution of such specific assets or any part thereof and may determine that cash payments shall be made to any members upon the footing of the value so fixed in order to adjust the rights of all parties,and may vest any such specific assets in trustees as may seem expedient to the directors.
