Analytical formulae are presented for the first time to describe the shift in the resonance wavelength of LPG in response to etching of the fiber cladding or a change in the external refractive index. The accuracy of the formula is confirmed by comparision with numerical simulations and experimental results. We demonstrated that the resonance wavelengths of an etched LPG are more sensitive refractive index than those of an unetched grating. The bending properties of long period fiber grating written in different type fiber are studied experimentally. The transmission peaks and the central wavelength of LPG change with the bending of the fiber. A new peak appears at the shorter wavelength when the fiber is being bent. The changes of the peaks are different for different photosensitive fiber. Those properties have broad application foreground in fiber sensors and tunable filters.

分别从理论和实验上对长周期光栅的折射率特性以及光纤包层半径对长周期光栅特性的影响进行了研究，首次给出了描述光纤包层半径腐蚀和外界折射率改变与长周期光栅共振波长关系的理论表达式，实验与理论和数据模拟的结果很好符合，利用腐蚀光纤包层的方法可以有效地提高LPG的折射率灵敏度；对不同光纤中写入的长周期光栅的弯曲特性进行了实验研究，LPG的透射峰形状及其中心波长随光纤弯曲而发生变化，并且随着弯曲将在短波方向出现新的透射峰，其透射峰的变化规律因所用光敏光纤的不同而不同，这一特性在光纤传感和可调谐滤波器方面有重要的应用前景。

His level precludes tampering with filesystems by unmounting them, but also inhibits running newfs(8) while the system is multi-user.

高安全模式-和安全模式一样，又多加了不管硬碟有没有被 mount 起来，除了 mount(2)之外都不能写入。

To meet the needs, a novel low-noise fiber laser with compound cavity structure is designed. The stable single-mode operation is realized by using a transient self-written fiber grating, produced by the effect of saturable absorption within a section of unpumped erbium-doped fiber, as narrow band filter for mode selecting and linewidth squeezing. Through optical path modification, the spectral signal-to-noise ratio is better than 62 dB.

激光器采用复合腔结构，以掺铒光纤作为工作物质，通过在未被抽运的掺铒光纤中形成的瞬态自写入光纤光栅的窄带滤波特性进行选模和压窄线宽，产生稳定的单频激光输出；经过光路改进，激光输出光谱信噪比优于62 dB；利用光电负反馈电路，弛豫振荡峰下降了约25 dB，低频段强度噪声也大为改善，有效地抑制了光源的强度噪声。

This is unsecure, since this includes read and write methods, but it will suffice for this demonstration.

心里还是有些不安，因为这包括了阅读和写入方法，但它已经足够起示范作用了。

Writing unvalidated user input to log files can allow an attacker to forge log entries or inject malicious content into the logs..

将一个没有过经过验证的用户输入写入日志文件中将允许攻击者伪造日志输入或者将恶意的内容注入到日志中。

By users, so it must be writeable by the user that the web server

这个文件同样也是用户操作提交与CGI命令写入的地方，所以这个文件必须对于相关服务可写，一般是针对Apache的宿主用户可写。

Copying filenames to the clipboard, replacing text within many files and making groups of files and folders writeable is just as easy.

复制文件名到剪贴板，替换文字的许多文件和决策群体的文件和文件夹写入一样简单。

The Writeable property is a boolean value indicating if the file can be written.

Writeable 属性表示文件是否可写入的波尔值。

"Nothing in the natural history of man", writes the Duke of Argyll,"can be more certain than that morally and intellectually and physically he can and often does sink from a higher to a lower level".

&没有在自然史的男子&，写入阿盖尔公爵&，可以更加肯定比在道义上和智力上和体力，他可以，而且往往不下沉，从较高的到较低的水平&。

Latterly, the reluctance of his party first to make common cause with the Scottish Nationalists, then to put euthanasia in its manifesto, made him choose in 2001 to stand, not altogether gloriously, as an independent.

近来，由于他的政党不愿通过首先与苏格兰民族党合作继而将安乐死写入其竞选宣言，愤愤不平的他于2001年决定独立竞选。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
