能结合的

A secure system consists of many sub——systems, even though every one of those sub-systems satisfies a certain security property, the composed system may not be secure, i.e. the composition maybe not satisfy the security property. It does mean that the security property should be composable.

安全系统是由许多子系统组成，每一子系统都必须满足一定的安全性质，但这不能保证由这些子系统组合而成的系统也是安全的，即组合的系统不一定也满足给定的安全性质，所以要求系统的安全性质满足可结合性。

What we have considered is only to estimate the situation of globalization with the combination of the Chinese situation and feature, then from the Chinese reality and benefit point of view to make a set of development strategy and countermeasure participate correctively in the process of globalization.

但是我们也应看到，全球化归根到底是个发展问题，不管它带来多少利与弊，我国对它都不能采取回避的态度，所将考虑的只能是如何清醒地估计局势，结合我国的国情和特点，从本国的实际情况和国家民族的最大利益出发，制定一套正确的参与全球化进程的发展战略和应对措施。

Using DFT combined with the orbital localized approach and Xu's covalence new concepts on a molecular fragment, it is concluded that the covalence of copper atom is 7 in 〓-type clusters and in inorganic fullerene-like molecule 〓, and there are Cu-Cu single bonds in 〓-type clusters.

应用DFT结合轨道定域化的方法和分子片共价的新概念，提出了在〓类簇合物和无机类富勒烯分子〓〓中Cu原子的共价为7，以及化合物中Cu-Cu单键的存在；解释了通常认为这类化合物中Cu-Cu之间没有成键作用而又不能回答较短的Cu-Cu键长的问题。

A theoretical model for calculating the cutting angle with different crystal planes, orientations and tool orthogonal rakes are described in this paper. It is built with the ultra-precision cutting model by the principle of the maximum specific energy of shear deformation and the mechanism of change of the shear modulus with...

本文利用剪切变形比能最大及单晶材料不同晶面晶向剪切弹性模量不同的原理，结合超精密切削模型，从理论上计算出不同晶面、不同晶向及不同刀具前角超精密切削条件下的剪切角，得到其在不同切削条件下的变化规律，并由此解释了切削加工中由KDP晶体各向异性所导致的工件表面粗糙度的各向异性。

In addition, the low-temperature heat utilization in deaeration of desahed water and temperature elevation of deaerated water is explored on the basis of refinery system integration and optimization.
