不是必要的

The four documentary sources of the Pentateuch thus far descried were combined not by any one individual; critics require rather three different stages of combination: first, a Yahwistic redactor RXX or RX combined J and E with a view of harmonizing them, and adapting them to Deuteronomic ideas; this happened either before or after the redaction of D.

这四个文件来源的摩西五迄今descried合并不是由任何一个个人；批评需要而三个不同阶段的结合：第一， Yahwistic redactor RXX或RX结合J和E与检视加以统一，并使其适应Deuteronomic观念；这一事件发生之前或之后编辑4第二，在D在完成了公元前6世纪，一个redactor ，或者一所学校的编纂，充满精神的D合并后的文件乙脑纳入JED介绍但是必要的修改，以确保一致性。

The first person who appeared upon the steep stone steps was a boy in corduroy trousers and a dark linen smock-frock, who shambled down the stairs with a good deal of unnecessary clatter of his hobnailed shoes, and who was red in the face from the exertion of blowing the bellows of the old organ.

首先出现在很陡的石级上的，是一个男孩，他穿着灯芯绒裤子和黑色亚麻布长罩衫，拖拖沓沓地走下石级时，钉着平头钉的靴子弄出了很多不必要的喀啦喀啦的声音，他刚才使劲儿吹管风琴的风箱，脸还涨得通红哩。

A new theoretical model, the 2CLJDQP potential function, was developed for linear molecules, which takes into account dipole, quadrupole and induction effects as well as the rotation of the dipole out of the molecular axis. The energy parameters were optimized for various types of fluids. With the modified mixing rules, the potential parameters obtained from homonuclear molecules can be used to calculate the second virial coefficients of heteronuclear molecules. The model was also successfully extended to triatomic molecules. Analysis of the contributions to the second virial coefficients of long-range interactions shows that the molecular interactions introduced in the present model, such as, the induction effects, cannot be neglected.

建立了全新的线型分子2CLJDQP势能模型，考虑了偶极作用、四极作用及诱导作用的影响，还考虑了极轴与分子轴不平行的情况；回归了多种线型分子的势能参数；通过改进混合规则，可应用同核线型分子的势能参数直接计算异核线型分子的第二维里系数；扩展该模型可用于线型三原子分子计算；讨论了各长程引力项对第二维里系数的贡献，结果表明本模型引入诱导作用等是十分必要的。

To build a powerful socialist country it is imperative to have a strong and unified central leadership and unified planning and discipline throughout the country; disruption of this indispensable unity is impermissible

为了建设一个强大的社会主义国家，必须有中央的强有力的统一领导，必须有全国的统一计划和统一纪律，破坏这种必要的统一，是不允许的。

According to the analysis, we can conclude that the relations between Russia and the West is irreciprocal, the policy of speedup drawing close to the West have not afforded the necessary condition for the economic development in Russia.

在这一部分的分析可以得出结论认为，在同西方国家的经济关系中，俄罗斯是处于不对等的地位，结果，加速向西方靠拢的政策取向远没有为俄罗斯经济的发展提供必要的条件。

Of Piso all must think and say that his character is an excellent blend of firmness and gentleness, and that it would be hard to find anyone possessing a stronger love of leisure, or, on the other hand, more capable of action, and of taking the necessary measures without thrusting his activity upon our notice.

世人评价皮索大人说他的性格是坚定与优雅的绝妙混合，很难再找出一个人能比他更强烈的热爱文娱或是更有才干的了，能在不惹众人注意之下采取必要的行动。

All materials must be available to others. This means that commercial sources must be identified, proprietory materials must be patented prior to publication, and all cultures, strains or varieties on which the work is based must be deposited in an identified culture collection from which they can be obtained by others.

那个实验当然可以重复，不过每个实验都有它必要的条件，这个实验的条件首先就是要有相信实验可以成功的人，因为心念是有力量的可以改变水的微观结构，其实当年很多关于气功的实验已经多次证明了，只是后来被不理智的抹煞了。

If possible, also, they should be branched or reticulated with other ways of a similar class, so that no part of the town should finally be many minutes' walk from some one of them; and they should be made interesting by a process of planting and decoration, so that in necessarily passing through them, whether in going to or from the park, or to and from business, some substantial recreative advantage may be incidentally gained.

如果可能，它们还应该在一个简单明确的枝状或网状系统中，这样从城市中的任何一部分都不会花费很长时间来到达另外一处；并且也应该通过种植和装饰的来是其充满趣味，这样，在必要的穿行中，无论是去公园还是从公园返回，或者往返工作之间，都要使人顺便获得实实在在的休闲。

The damage deformation when ship rocking happens, we should mainly concentrate on the area that the rock touches the structure, and this adumbrates that the improvement of resisting collision to the hull structure should focus on the weak area which can be easily collided, the structure strengthening of bigger range is not necessarily.

船舶触礁时损伤变形主要集中于结构与礁石相接触的区域，这预示着船体结构抗撞能力的提高应着眼于容易遭受撞击的薄弱区域，大范围的结构增强措施是不必要的。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
