查询词典 turbulence

Without resuspension, longitudinal deposition of suspended sediment was observed under conditions of existing turbulence .

研究床沙不起悬但存在紊动条件下的悬浮泥沙沿程淤积，这种淤积常发生在水库、沉沙池等较深水体中。

The calculated result of the distribution of the mean flow velocity and turbulence energy has been given under the different calculated conditions,such as model functions and disposition of grid and Reynold numbers...

分别给出了时均流速和紊流动能分布的计算结果，并分别与实验结果进行比较和分析，得知在不同计算条件下对计算结果的影响程度，计算结果与实验结果较好符合。

Although the standard k-ε turbulence model has been proved to be a model adapting a large range of conditions, it does not fit in with the cases where the normal Reynold stress of fluid is of great importance. As generally known, these cases include at least some cases where recirculation or secondary flow takes place.

在目前多数研究中，采用的湍流模型为标准k-ε湍流模型，这种模型虽已被证实是一种适应范围较大的模型，但其并不适用于流体中雷诺正应力占重要作用的情况，目前所知，具有回流区和二次流的一些流动便属于此种情况。

The semi freedom short circuit is superposed by parallel plane flow, confluence and ringy turbulence jet.

半自由状态下的短路流场是平行平面流、环形紊流射流及汇流叠加而成。

In the 1971 paper [90] introducing strange attractor, Ruelle and Takens indicated how the ideas in nonlinear dynamics could be used to explain how turbulence developed in fluid flow.

在1971年文章〔90〕中 Ruelle 和 Takens 引进了奇怪吸引子的概念，指出怎样将非线性动力学中的思想应用于解释流体流动中湍流的产生。

The research conducted in the station included atmospheric boundary layer research including radiation and soil ob- servation, atmospheric turbulence and radiation system research, wind temperature profile research, radiosonde ob- servation research, sand and dust storm observation, glacier change observation, environmental study of surface process and geodynamic research.

为开展高喜马拉雅地区地质构造一气候反馈作用的研究，中国科学院青藏高原研究所于2004年开始在珠峰地区建立了综合观测研究站，并于2004年下半年开始相继开展了大气边界层、大气湍流和辐射系统、风温廓线、无线电探空系统、沙尘暴观测、冰川变化等大气科学观测研究、地表过程的环境研究和地球动力学研究。

The Turbulence Slope calculations are based on the averaged tachogram and expressed in ms per RR interval.

计算振荡斜率 TS 时，以平均的阶梯图为基础， TS 值以每个 RR 间期多少毫秒为计量单位。

The Turbulence Slope corresponds to the steepest slope of the linear regression line for each sequence of five consecutive normal intervals in the local tachogram.

振荡斜率 TS 指数是对连续的5个正常心搏的 RR 间期的阶梯图进行线性回归处理，取其中最大的斜率。

Animals, as material, were used to study the toxicity of outer substance and made sure the estrogen effect of BBP by whole animal experiment, and the chronic toxicity of BBP was studied, designed and valued through several dosages and different exposed time. The result showed that BBP could make testis, epididymis and prostate withdrawl. Tectology changes were observed in testis, epididymis and liver. Especially the atrophy and degeneration of seminiferous tubules, decrease of spermatogenic cell and the turbulence of Sertoli cell and spermatogenic cell of seminiferous epithelium were also observed. The linkage between cells vanished.

明确了BBP的雌激素效应，并分别用多剂量和不同染毒时间来研究、设计、评价BBP在体内的慢性毒性，结果表明：BBP能引起雄鼠睾丸、前列腺、附睾性腺的萎缩和肝脏肿大，改变睾丸、前列腺、肝脏的组织形态学，尤其引起睾丸曲细精管萎缩、变性，各级生精细胞减少，生精上皮内生精细胞和Sertoli细胞结构明显紊乱，细胞间连接结构消失等。

Many Timorese agree that beneath the superficial calm lurks a serious danger of renewed turbulence.

许多东帝汶人承认，平静的表面之下隐藏着一个新的动荡的严重危险。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
