查询词典 shifting

Recognizing that morphological change was the product of shifting gene frequencies, Fisher, Haldane and Wright developed sophisticated mathematical models to assess the relative effects of selectional pressure, mutation, and genetic drift on evolutionary change.

认识到形态变化的产物，是转移基因频率，费希尔，霍尔丹和赖特开发了先进的数学模型，以评估相对影响的选择性压力，突变，和遗传漂变的进化改变。

In this paper, we present the idea of virtual plate for aspheric testing based on moire phase-shifting technology, i.e. when testing steep aspheric wavefronts, interferometry directly used CCD camera for high resolution to obtain supervision with interferometry saved in the frame memory produces moire patterns. Finally, we cancel the noise by means of low pass frequency .

在检测非球面波前时，我们改变以往传统的零位补偿检验手段，而利用高分辨率的CCD相机直接对被检非球面进行数据采样，并把获得的干涉条纹和预先储存在储存器里的参考干涉图进行叠加，从而得到电子莫尔条纹，然后对获得的电子莫尔条纹进行低通滤波，滤掉噪声中含有的高频成分，以提高图像的信噪比。

In electronic moire phase-shifting virtual plane technology, we began to research testing for the large departures from referent wavefronts and change the pattern of Offner Null testing in conventional aspheric testing, finally present the idea of electronic virtual plane.

在电子莫尔虚拟样板中，改变了传统非球面检测Offner零位检测手段，而采用直接对被测表面进行采样，获得虚拟样板的检测技术。

Shifting the pitch of digitally sampled sounds is an operation performed by a number of commercially available devices (sampling synthesizers, harmonizers and vocoders) as well as by the software of many computer speech languages.

改变语音信号的音调是许多商用设备的一种功能，如采样合成器、调和器、声码器，也能被许多计算机音乐语言软件实现，然而，许多成熟的算法由于技术的保密性，不公开；一些公开的算法均有各种各样的问题。

Being a case of code-switching in the broad sense, shifting of vocatives should be regarded as one kind of linguistic choice or pragmatic strategy.

称呼语转换，作为广义语码转换(code-switching)的一个部分，应视为一种言语选择或曰语用策略。

Based on Verschueren's Adaptation Theory, this paper analyses and interprets English and Chinese data and concludes that the shifting of vocatives is actually the outcome of the inter-adaptation of linguistic elements for language users' physical world, social world and mental world.

本文以Verschueren的语言顺应性理论为基本框架，分析、解读英汉跨语言的语料，继而指出称呼语转换是与语言使用者的物理世界、社交世界、心理世界等相互顺应之结果。

When a population is urbanising, even though its productivity is shifting from the agricultural to the industrial level, consumption habits remain rural that is, anything beyond necessities is viewed as luxury and is minimised.

在城市化进程中，尽管生产率正从农业水平转向工业水平，但消费习惯仍然带有农村性质——也就是说，必需品之外的东西仍被视为奢侈品，并被减至最低水平。
