For example, if R4 has a value of 10 kΩ, a trip voltage of 18V would require R3 to have a value of 62 kΩ. When choosing values for R3 and R4 to set the desired trip voltage, ensure that they are large enough that the potential divider will not excessively load the supply.

例如，如果R4值为10k，18V的跳闸电压需要R3阻值为62k.R3 和 R4选择适当的阻值来设置需要的跳闸电压值，确保它们足够大以至于潜在分压器不会过度负荷供应。

The minor principal stress of slab, the maximum acceleration in up-down stream direction and permanent deformation of the dam body for three-directional earthquake excitation are obviously different from those for unidirectional and two-directional earthquake loading.

计算表明，多向地震动下的面板峰值小主应力、顺河向峰值加速度及坝体的永久变形均与单向和双向输入时显著不同，实际工程计算时应同时考虑三个方向的地震动；振动型地震激励引起的坝体反应明显大于冲击型地震激励；随着地震动强度的增加，峰值加速度、峰值剪应变、面板应力和周边缝变形等增加；面板刚度对面板的应力值和周边缝的变位具有较大影响，当面板模量取值较低时，计算所得到的"面板"应力集中部位不甚明显，计算结论为新型的"土工膜面板堆石坝"提供了理论依据。

The value changes for your program only, not for GDB itself. value may be any string; the values of environment variables are just strings, and any interpretation is supplied by your program itself. The value parameter is optional; if it is eliminated, the variable is set to a null value.

这个改变只针对你的程序，不影响 GDB 本身。value 可以是任何字符串，环境变量的值仅仅是字符串，任何解释都是你的程序自己的。value 参数是可选的，如果没有，变量会设为空值。

However, undead can use Psychokinesis powers --- but they substitute their Charisma ability score as the key modifier with these powers.

不过，不死生物可以使用心灵转化系异能——但它们以魅力调整值作为该系异能的关键属性调整值。

The spatial distribution pattern of the factors shows that distinct radiolarian assemblages are closely related to water mass, ocean current and hydrographic conditions.(4) The test of a new radiolarian-based transfer function to estimate mean-annual sea surface temperature and se

利用57个样品的统计数据，对估计表层海水年平均温度和其变化范围的放射虫转换函数（Pisias，1997）的检验结果表明，其估计误差为6℃，实际值与估计值的相关性差，可靠性低，不适合于本区使用。

For getting the major characteristic edges without confusions by undesired structures like muscle edges, we integrate a star-like edge detection filter named "Asterisk Filter" with the Canny Edge Detection in the image preprocessing. In addition, we also propose a new contour tracking method named "One-Pixel Rolling Ball Contour Tracking" for getting the boundary information in a binary image which is a link-list data structure. Instead of using a regression curvature estimator, PCA is used for better curvature estimation from a discrete bony contour.

为了从影像上取得骨头特徵边缘，将不重要的肌肉视为杂讯滤除，我们引用一种星形滤波器－Asterisk Filter，搭配Canny边缘检测法，做为这类影像的前处理；另外，为了将骨头的边缘精确地追踪出来，我们提出滚球边界追踪法，来对二值化影像进行边缘追踪，藉此获得边缘的串列资料结构；我们采用以主成分分析(Principle Component Analysis，简称PCA)取代原本以回归方法来计算的曲率，以取得更佳的曲率估测值，其可提高计算之参数的准确性。

The simulation results showed that the neural network model given in this paper is capable of forecasting the behavior of nucleation rate exactly and rapidly, and the maximum relative error does not exceed 5.9% as compared with measured values.

仿真结果表明，利用文中所提出的神经网络模型能够较准确、快速地预测结晶成核速率的变化，预测值与测量值的最大相对误差不超过5.9%，表明该网络预测模型有很大的实用性。

This function is not required to return the closest match, and for performance reasons a close

此函数不要求返回最接近的值，作为执行的理由，能够返回了一个接近的值。

If Memcached can carry connective moment in the client, do an identity examine and verify a lot of, perhaps restrict the Ip address that join client carries, be like it seems that also is not very difficult, regrettablly I am already old need not C, forget about the same, who has fun at join this function ah Iptables ah Robbin writes Balaschen to write a flaw that discovers Memcached, memcached does not have attestation mechanism, the client inside the local area network is carried, want to know the Key of the port of Memcached and Cache is worth only, can be accessed and change the value of Cache, put in potential security hidden danger.

要是memcached能在客户端连接的时候，做个身份审核就好多了，或者限制连接客户端的ip地址，看起来好像也不是很难，可惜我已经多年不用C了，都忘差不多，有谁有兴趣加入这个功能啊 iptables啊 robbin 写道balaschen 写道发现memcached的一个缺陷，memcached没有认证机制，局域网内的客户端，只要知道memcached的端口和cache的key值，就可以存取和改变cache的值，存在潜在的安全性隐患。

This paper built water quality assessment model based on some basic introduction to PP. It made several conclusions as follows: PP model was stable when sample size was no less than 20. It run much faster when the range of projection vector was constrained between 0 and 1. Accelerated genetic algorithm should be recommended because of its unique advantages. Using scatter diagram of making comparison directly was more convenient than using regression model.

该文在介绍该模型基本计算步骤的基础上，经建模分析，得出：各评价等级取值范围内样本个数不小于20即可具有较好的稳定性，投影向量分量的取值范围为[0，1]时更有利于提高计算速度，选用加速遗传算法寻优时间更短，使用图解法或直接比较法更为方便和快捷。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
