Bt the same time, the concept of utility computing became a focus of IT design and operations. Bs Nick Darr observed in hellos book The Big Switch, computing services infrastructure was beginning to parallel the development of electricity as a utility. Wouldn't it be great if you could purchase compute resources, on demand, only paying for what you need, when you need it?

同时，作用计算的观点成为IT预设和操作的焦点正如Nick Darr在The Big Switch一书中所说，计算办事根蒂根基举措措施已起头成长成象电力公用举措措施一样要是你能仅在需要的时辰采办计算资源，付出你所用的部分，这莫非不是一件很正确的工作吗？

One of them is that it is not decidable and the other is that all the task knowledge in it has to be defined on an abstract logic level so it can not describe the concrete attributes of tasks.

其中，计算逻辑属于交互计算理论[4]，进程代数主要描述进程之间的通信，属于并发计算理论，两者都不太适合描述主体之间的资源交互。

The masses of N and Δ baryons are calculated based on the confining potential amended or not in chiral SU (3) quark model and three-body theory method. The results shown that amendment can improve some values, but the improvement is still not satisfactory and the quark model can described octet and decuplet well but excited baryons.

利用手征SU(3)夸克模型和三体理论方法，在考虑禁闭势带修正项和不带修正项两种情况下，计算了N和Δ重子质量。N和Δ重子谱的计算结果表明，增加修正项能改善一些计算值，但改善程度仍然不是很令人满意；SU(3)夸克模型能够很好描述重子的八重态和十重态，但不能很好地描述激发态的重子。

为了了解旋转磁场下真空精炼装置内的脱碳反应，对RH装置内钢液流场与脱碳过程进行了耦合计算；采用修正的均相流模型计算流场，避免了先前的一些不具推广性的方法，如简化计算区域或者预先规定含气率分布等。

The third part of this thesis is reactive simulating calculation In this section, some well-known auxiliaries are selected to compute in density functional theory B3LYP on Gaussian 03, from which the relationship between reaction active energies of transition states and enantiomeric excess of chiral products homoallylic alcohols isobtained based on relative reactive ratio theory. Using this relationship, calculations on the reaction of more than eight auxiliaries with four other aldehydes are carried out in AMI and MNDO, proving that N,N\'-dibenzyl tartamide has higher enantioselectivity than others in this reaction.

第三部分为计算化学部分，运用密度泛函理论B3LYP方法在Gaussian03软件上对已经报道的几种手性配体参与的醛不对称烯丙基化反应过程进行模拟计算，基于相对反应速率理论找出两种构型过渡态间活化能的差异与产物光学收率之间的关系；并以此为基础，用AM1和MNDO方法对上述合成的几种配体控制的反应过程进行量化计算，从而在理论上证实了N-苄基酒石酸二酰胺配体在醛的不对称烯丙基化反应中具有较高的立体选择性。

The dependence of the characteristic ratio and the first interaction energy of PDMS is numerically calculated by analyzed the results of various models, we found that it is rather necessary to consider the structure of disubstituted groups if the polymers of rotational-isomeric-state model are calculated.
