选取范围 meaning in English
select twain_source
Examples
- The expert points out : what chinese myopic incidence of a disease rises is fast , the influence occupational of talent of chinese high quality is chosen , of personnel of contractible not little special profession choose limits
专家指出：中国近视发病率上升之快，将影响中国高素质人才职业的筛选，缩小不少非凡职业人员的选取范围。 - As for the numericial mthods we present a method using newton iteration and lp ( lift - projection ) iteration to slove inverse real symmetric eigenvalue problems . then wo can choose any starting points , then wo can get good starting value for the purpose of the preconditioning the numerical examples show the method is efficient and available
对于数值算法，将lp迭代和一般的newton迭代法结合起来求解含参变量的实对称矩阵特征值反问题， lp迭代预处理了newton迭代法的初始值，拓宽了newton迭代法初始值的选取范围，数值例子也说明lp ? newton法具有较高的效率和实用性。 - From theoretical analysis , we know the existing demodulation methods have limitations as following : one is that the subtraction of the two signals frequencies will display as the result of demodulation when we demodulate two time - domain adding signals without modulating information ( fault information ) ; the other one is that aliasing phenomenon will occur as a result of getting absolute value , detection or square in the process of generalized demodulation analysis , such phenomenon will result in some superfluous frequency composition on the frequency spectrum , which will puzzle the detec tion of mechanical vibration . if the sampling frequency is selected from a suitable range , the aliasing phenomenon will be avoided ; the last one is that aliasing frequencies will be produced in zoom demodulation analysis because this algorithm cannot employ digital low - pass filtering to avert the folding frequencies of higher harmonics in the process of zoom sub - sampling
现有的解调分析方法存在以下三种局限性：将不包括调制信息(故障信息)的两时域相加信号，也以其频率之差作为解调信号而解出；广义检波滤波解调分析中，由于取绝对值、检波或平方过程可能产生混频效应，在解调谱中表现为无法分析的频率成分，并由此推导出避免这种混频现象的采样频率的选取范围，从根本上避免此类误诊断的产生；几种细化解调分析新算法中，因为无法在细化分析的选抽时进行数字低通滤波，有可能会出现调制频率的高次谐波成分发生频率混叠而反折到低频部分的现象。 - Having a good grip of applications development , the system offers numerous characteristic functions , for instance , alkald has the powerful capability of chinese typesetting and auto - phoneticizing and formula typesetting , it can make any color transparent in image and animation , it can superpose words and any else object on video media , meanwhile it provides path animation and drag interaction etc . there are too many functions and details to narrate , just try it you will enjoy its facility and easiness
对动画的特殊支持蒙泰瑶光自身特有的动画驱动程序可对所有的动画进行去背景操作，支持网上流行的gif动画，这些功能将大大增加动画素材的选取范围。同时在蒙泰瑶光还提供自定义路径动画和定时动画组制作功能，方便课件中动画的应用。
