查询词典 threshold

Considering the design parameters of the BEPCⅡ, in the case of one cavity type being adopted, the thesis analyzes the RF performance of accelerating mode, the suppression of higher order modes , and the restriction caused by HOMs against beam current threshold.

结合BEPCⅡ的设计参数，论文对其中一种腔型在BEPCⅡ上使用时加速模式的微波性能、高次模的抑制效果以及高次模对储存流强阈值的限制等方面进行了分析，并在铝模型腔上测量了加铁氧体高次模抑制器前后，超导腔中各种谐振模式的有载品质因子及其频率的分布。

The major issues with GPS, namely 2 feet vertical guidance accuracy near the runway threshold and the integrity of the system has not been able to match historical ICAO standards and practices.

gps主要的问题是，跑到末端的垂直导航精确度是2英尺，系统的完整性（就是没有人为因素可以增加导航误差。。

"These areas are most susceptible to climate warming in the coming century in Antarctica, because they are the closest to the melt threshold," says climatologist Andrew Monaghan of the National Center for Atmospheric Research in Boulder, Colo., who was not involved in this study but reviewed the research.

&在下个世纪，南极沿海地区是南极洲最容易受到气候变暖影响的地区，因为这些地区最接近融化的极限，&科罗拉多州博尔德市美国国家大气研究中心的气候学家安德鲁·莫纳汉说。莫纳汉没有参与这项研究，但是对该研究作了评论。

Firstly, edge extracting is conducted with a laplace operator for a k frame image of fk and a k-1 frame image of fk-1 collected by a camera; secondly, difference calculus is conducted for images of two frames whose edge is extracted, and a difference image of D is obtained; thirdly, average filtering and binary processing is conducted for the difference image of D, fourthly, the image which is processed of binary is judged, i.e. when the difference of a pixel in the difference image is more than the set threshold value, the pixel is confirmed as a target pixel; otherwise, the pixel is a static background pixel.

首先对摄像头采集的第k帧图像f k和第k-1帧图像f k-1分别采用laplace算子进行边缘提取，然后对经过边缘提取的两帧图像进行差分运算，得到差分图像D，然后对差分图像D进行均值滤波和二值化处理，最后对二值化后的图象进行判断，即认为当差分图像中某一个像素的差大于设定的阈值时，则认为该像素是目标像素，反之则认为是静止不动的背景像素。

"Yes, now you can give yourself airs," she said, you have got what you wanted.

"对了，您现在高兴了，"她说道，这是您所期待的。

Then the LORD said to me: Rebel Israel is inwardly more just than traitorous Judah.

上主于是对我说：＂失节的以色列比失信的犹大，更显得正义。
