The unflatness of amplified spontaneous emission noise and its impacts imposed on the performance of the off-center narrow filter polarization-nulling method when monitoring the in-band optical signal-to-noise ratio of dense wavelength division multiplexing system are analyzed, and a modified method by introducing an unflat factor in the calculation of OSNR is proposed.

分析了累积自发辐射噪声的非平坦特性，在已有窄带离心偏振置零法测量波分复用系统中带内光信噪比的基础上，分析该方法在噪声非平坦条件下存在的问题，提出了在光信噪比的计算中引入修正因子。

Unlike the uniform linear array,the unform circular array is able to provide 360°azimuthal coverage,within the mode space,it has the covariance matrix of the Toeplitz-like struture while all sources are uncorrelated,with which the noise variance can be made out directly,note that will eliminate an eigendecomposition when the ESPRIT is applied,consequently reduce the computational load.

对于均匀圆形阵列，在信源都是非相干信源的情形下，由于模式变换后的协方差矩阵具有类Toeplitz的特征，因此，我们可以根据这种特殊的性质，直接求得噪声分量，因此若使用ESPRIT算法进行波达方向估计，就可以避免第一次特征分解，较大程度上减少了计算量。

In this paper, the noise sources of the EBCCD imaging system have been analyzed and a SNR model has been established. It shows that the SNR of output image is related not only to the input illuminance on the cathode but also to the spatial frequency of the input image. This has been proved by a series of experiment. Unperfectness of the detecting equation has been pointed out in this paper.

分析了电子轰击电荷耦合器件微光成像系统的噪声源，建立了系统的信噪比模型，指出了在微光成像系统本身的增益和量子效率等性能确定的条件下，成像系统输出图像信噪比不仅仅与输入面照度有关，还与输入图像的空间频率有关，并通过实验得到了证明，指出了经典的图像探测方程的不完善之处。

Ltd. That case, I think, authorizes four propositions first, that, where a contract is ex facie illegal, the Court will not enforce it, whether the illegality is pleaded or not; secondly, that, where, as here, the contract is not ex facie illegal, evidence of extraneous circumstances tending to show that it has an illegal object should not be admitted unless the circumstances relied on are pleaded; thirdly, that, where unpleaded facts, which taken by themselves show an illegal object, have been revealed in evidence (because, perhaps, no objection was raised or because they were adduced for some other purpose), the Court should not act on them unless it is satisfied that the whole of the relevant circumstances are before it; but, fourthly, that, where the Court is satisfied that all the relevant facts are before it and it can see clearly from them that the contract had an illegal object, it may not enforce the contract, whether the facts were pleaded or not.

Believe or not, this is the life of a working aritste - uncertain, unsecure, unknown but keeping awake to be 24 hours stand by.

信不信由你，这就是一个艺人的工作最好的写照----不确定，没安全感，不清楚，却要保持清醒，24小时stand by。

She hadn't read the letter and so was unware of its contents.

She had written letters to the local paper, even to a national, protesting about a projected by-pass to her vilI was puzzled!

她给当地报纸写了信，甚至给全国性的报纸也写了信，对拟将在她们村子里修建小路的方案表示抗议。

I know it is romantic to send sweet words to each other on MSN, and lovely to send interactive images on QQ. And I also know from your short messages that you really care about me. But I am tired of sending a red lip image when I want to kiss you, or a waggling mouse image when I want to hug you. Neither do i want to do nothing but read the short messages you sent me again and again in the evening until I fall aleep.

我知道两个人在MSN上甜言蜜语很是浪漫，我知道两个人在QQ中发的互动图标是那么地可爱动人，我知道短信中的你总是对我细心呵护，关怀的无微不至，可是我不想亲吻只能用一个血红的唇印图标，可是我不想拥抱只能在QQ中用一个小老鼠左摇右摆，可是我不想一到了晚上就只能一遍一遍地看着短信然后睡觉。
