Hence, it is worthwhile to develop image understanding system aimed at specific task and problem, utilizing some knowledge reasonably and advisably to reduce present inefficient algorithm uncertainty, improve processing accuracy and reduce unnecessary computation.

在此情况下，从具体任务出发，针对某个具体任务和问题建立专用应用系统，同时合理和适当的引入一些知识，以减小问题求解的不确定性、提高理解结果的准确性、减少不必要的计算是有一定的现实意义的。

An alternate Director shall be entitled to contract and be interested in and benefit from contracts or arrangements or transactions and to be repaid expenses and to be indemnified by the Company to the same extent mutatis mutandis as if he were a Director but he shall not be entitled to receive from the Company any fee in his capacity as an alternate Director except only such part, if any, of the remuneration otherwise payable to his appointor as such appointor may by Notice to the Company from time to time direct.

代理董事将被授权签署合约并从合约或安排、交易中获利，还可有权报销相关花费、为公司目的以董事身份作出必要的行为而获得公司的补偿，但作为代理董事时则不能被授权收悉来自公司的任何酬金，如有可能，也仅能收悉部分，而上述酬金指支付给指定该代理董事的董事的报酬，对该报酬的支付可以是有该指定代理董事的董事在不同时间以通知形式向公司作出的。

In the opinion of St Peter Damian it is unnecessary and blameworthy curiosity to inquire into those things that the evangelists did not tell us, and he specifies the parentage of the Blessed Virgin Mary as an example.

在舆论的圣彼得达米安这是不必要的，受责备的好奇心，调查这些事情的福音派没有告诉我们，他指定了父母的祝福圣母作为一个例子。

On the other hand,the structure of differential operator and that of difference operator are very similar,therefore,it is a urgent task to find in the current scientific research a new theoretical framework,which can unify the continuous systems and the discrete ones for the sake of study in order to not only avoid unnecessary repetition in work but also be able to make better insight into the nature of the differences among different systems.

因此，能否找到一个新的理论框架，将连续系统与离散系统统一(来源：9dABC论9e9e文网www.abclunwen.com)起来进行研究，从而避免不必要的重复工作，且能更好的洞察不同系统之间的本质差异，已是当前科学研究的当务之急。

We proved the nonlinear ergodic theorem for semitopological semigroups of asymptotically nonexpansive mappings in the uniformly convex Banach space with the Frechet differentiable norm. We also point out that some key conditions in [23] [24] are unnecessary.

本文第一章主要将文[23][24]中的结论推广到殆轨道的情形，这不仅回答了Lau-Takahashi[24］中的问题，而且指出了文［23］［24]中的某些关键条件是不必要的。

Explore the connection between family values and "greater", other-than-general values, for example, the way in which Take a modern case of the quarrel between the duties of office and the imperatives of religion: a doctor is devoted to reducing pain and preserving life but Christian Science parents refuse permission to let the doctor give a necessary bone-marrow transplant; in their view, faith alone does the healing and what is more, permitting the treatment would endanger the child's life because it would issue from lack of faith.

探讨家庭价值与更「深刻」、非一般价值间的联系，举例来说，生活在现代，出现介於工作职责与宗教规范间的争论：医生的责任是解除痛苦、保存生命，但如果基督科学教的双亲拒绝让医生进行必要的骨髓移植手术，对双亲而言，信仰即足以诊治，而允许手术可能会危害到孩子的生命-这意味信仰不虔诚。

In the precision detection of a millimeter wave, the encounter of the detector and the objects can not be forecasted totally because of a lot of noise and disturbance existing in the complex battlefield, it will cause fantasticality and distortion of the echo retaked by the detector, and the stably of the echo become bad, as a result, it will reflect the result of the detection, so it is necessary to filter the echo retaked by detector.

在弹载毫米波精确探测系统中，由于复杂多变的战场环境中存在大量的干扰及噪声，探测器与目标的交会姿态不能完全预测，造成探测器获取目标回波产生奇异和变形，回波特征的稳定性变差，从而影响了目标的探测和识别，因此对探测器的回波进行有效的滤波处理是十分必要的。

I wish every corner of the world is full of freedom, peace, happiness and wealth because of your right and harmonious ideas. So the world would decrease some unnecessary wrangle and fatuity. Everybody's happiness is our happiness.

希望你们一如既往地用和谐的方式让世界的每个角落充满祥和的自由、富饶的欢乐，少一些愚昧和不必要的纷争，因为所有人的幸福才是我们的幸福。

The main purpose is to store files temporarily ,so we can delay the time to allocate file to its original filesystem until file size is more certain to avoid file fragmentation.(2) Purpose a writeback algorithm, considering file spatial locality, to flush continuous and near blocks together to reduce writeback time.

其主要的目的是暂时储存新建立的档案，延迟档案分配给其真正所属的档案系统的时间，等到较为确定档案大小后再进行分配，以避免档案 fragmentation的情形并减少不必要的I/O；(2)修改以往以档案为单位将资料写回的演算法，加入了考虑每个要写回的block在磁碟上相对应的位置，让较连续且较邻近的资料一起写回，减少写回所需的时间

Further,we findalso that groups in Saito's results may be replaced by right groups;secondly we mainly investigatethe semidirect products and wreath products of P-regular semigroups;Finally we shallcharacterize the sandwich matrice of completely simple P-regular semigroups,and investigate thestructure of P-regular semigroup whose C-set satisfies a permutation identity.

在这一章中，首先指出Saito在研究半群的半直积和圈积时，对S的限制是不必要的，证明了Saito结果中群可换为右群；其次，研究P—正则半群的半直积和圈积；最后刻划了完全单P—正则半群的夹心阵和C—集满足置换恒等式的P—正则半群的结构。

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。
