失效

When should searching engine spider to get when requesting a certain URL 404 condition are responded to, know this URL namely already invalidation, index no longer this webpage, feedback to delete this URL denotive webpage from inside index database to data center, of course, delete a process to need for a long time likely, and when should searching engine to get 200 condition are responded to, can think this Url is effective, can index, can collect its index database, such result is these two different Url have identical content: Define the content of 404 wrong pages oneself, this meeting is brought about appear duplicate webpage problem.

当搜索引擎蜘蛛在请求某个URL时得到404状态回应时，即知道该URL已经失效，便不再索引该网页，并向数据中心反馈将该URL表示的网页从索引数据库中删除，当然，删除过程有可能需要很长时间，而当搜索引擎得到200状态回应时，则会认为该url是有效的，便会去索引，并会将其收录到索引数据库，这样的结果便是这两个不同的url具有完全相同的内容：自定义404错误页面的内容，这会导致出现复制网页问题。

The wear failure is mainly caused by the combined action of micro-cutting and fatigue desquamation, with fragmentation of carbides.

磨损失效形式为显微切削与疲劳剥落的复合，兼有碳化物碎裂。

But in practical conditions, the assumption of white noise is not always true. When the noise model is not white, the traditional high resolution methods will be deteriorative and even invalid.

然而在实际环境中，白噪声的假设并不总是成立，当实际噪声不满足白噪声模型时，传统的高分辨方法的性能将会引起严重的恶化甚至失效。

For the smelting slags of exhausted automobile catalyst, a method for determination of trace amounts of platinum and palladium by plus-dual-wavelength overlapping spectrophotometry in dibenzyl dithiooxamide-SnCl2 system was developed.

针对失效汽车催化剂火法熔炼渣，研究了采用正峰双波长叠加，二苄基二硫代乙二酰胺-SnCl2体系萃取光度法测定渣中痕量铂钯的方法。

FastNet takes DHRLM as routing model, it implements a diffluent multi-point distribution algorithm like Bittorrent, but FastNet is different from Bittorrent which is an unstructured P2P system, it implements the idea according to the characteristics of resource locating algorithm in structured P2P network. Moreover FastNet adopts periodic fault-tolerant algorithm to ensure active, quick and reliable distribution of security-related content.

FastNet以DHRLM为路由模型，实现了类似于Bittorrent的多点分流内容分发算法，与Bittorrent不同的是，FastNet在结构化的P2P网络中根据定位算法的特点实现了该算法：同时，FastNet采取了周期性的容错算法保证在P2P节点动态失效的情况下仍然能够主动、快速、可靠地分发安全内容。

Independent directorship is an outside governance mechanism designed to make up for the deficiency of internal governance in fund governance.

独立董事制度是作为弥补基金治理机制中内部治理的失效而引入的一种外部治理机制。

Now this I say, that the testament which was confirmed by God, the law which was made after four hundred and thirty years, doth not disannul, to make the promise of no effect.

我是说：天主先前所正式立定的誓约，决不能为四百三十年以后成立的法律所废除，以致使恩许失效。

The failure analysis was carried out on the dissilient 12Cr1MoV steam pipe which was worked in the high-temperature 514 and atmospheric pressure 15.6MPa.

对在运行条件为514℃、15.6MPa下爆裂的12Cr1MoV高温导汽管进行了失效分析。

The method connects the exponentially attenuating dividable auto-correlation function which is often used in the study of the lubricating behaviors of rough surfaces, to the theoretical model for studying the contact behaviors of rough surfaces and it will be a foundation for studying the lubrication and failure problems of sliding frictional pairs with anisotropic surfaces.

第三章对Onions-Archard的理论接触模型进行扩展，给出了计算各向异性粗糙表面接触性能的简便方法，并将粗糙表面润滑效应研究中常用的表征粗糙表面的指数衰减可分自相关函数和粗糙表面接触性能研究的理论模型联系了起来，为研究混合润滑工况下各向异性粗糙表面摩擦副的润滑和失效问题提供了基础。

We now examine the performance of DONet with dynamic node joining, leaving, and failing.

现在我们在动态节点加入，离开和失效情况下，测试DONet的性能。

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。
