查询词典 centrifugal

The cavity can be divided into two typical zones: the Rayleigh_Benard-like convection zone governed by the centrifugal buoyancy force occupying the upper cavity, and the forced convection zone governed by the inertial-force down under. These two zones interact with each other via the exchange of mass, momentum and energy.

And starting from the inertia of the large number of text introduced by centrifugal force and the Coriolis force, and through the two of the more powerful and proven set out to explain the inertia force, the inertia of the process of doing a detailed description, And applying the theory with practical ways of his predecessors found that the real issue in the application and preliminary feasibility studies, for the simple inertia force for a definition and description.

并且又从惯性力出发用大量文字来介绍惯性离心力和科里奥利力，并通过对这两种力的阐述和证明更有力的来说明惯性力，对惯性力提出的过程做了详细的叙述，并运用理论结合实际的方法对前人发现的问题进行实际中的应用和初步论证，简单得对惯性力进行个定义和说明。

The numerical results were proved to be reliable by comparing with some published experimental data. The results show that, when only Coriolis force is in effect by omitting the centrifugal buoyancy force, the flow in the cavity is axi-symmetrically stable, the Coriolis force is a kind of resilience, and does not cause flow unstably.

研究结果表明：在哥氏力的单独作用下轴向通流旋转盘腔内的流动基本上是稳定的三维轴对称结构，即使有轻微的径向或周向振动发生，由于哥氏力是恢复力，对其有抑制作用，因此振动会随着流场的发展逐渐消失。

Particle size analysis; size analysis by air classification with centrifugal counterflow classifier

粒度分析。用离心筛分机的目视分析

Continuous multistage counterflow centrifugal dephenol extraction and reextraction regeneration of the extractor were studied and proper operating parameters determined.

在此基础上，进行了多级连续逆流离心萃取脱酚及萃取剂反萃再生的研究，确定了适宜的工艺操作参数。

Wu39-1,Wu43-1 and Wu50-2 were used to develop a handy extraction method of mtDNA in crucifer s on the basis of the sucrose-bedding method of mtDNA extraction and by means of four combinations of different centrifugal forces,differential centrifugation,and composition adjustment and dosage increase of buffer solution A.

以十字花科植物芸芥 Eruca sativa 、白菜型油菜 Brassica rapa 和甘蓝型油菜 Brassica napus ：武39- 1、武4 3- 1、武5 0 - 2为试材，在蔗糖衬垫法分离纯化m t DNA方法优点的基础上，通过4组不同离心力配比，采用差速离心法、改变缓冲液A的成分以及增加缓冲液的用量，建立了一种简便提取十字花科植物mt DNA方法。

The evolution of the hydrodynamic field was cyclic and each cycle may be divided into centrifugal flow stages when the basin subsides and receives deposits, and centripetal flow stage when the basin uplifts and is eroded.

地下水动力场演化具有旋回性，每个旋回可以分为两个阶段：①盆地沉降接受沉积时期的泥岩压榨水离心流阶段；②盆地抬升剥蚀阶段的大气水下渗向心流阶段。

The results indicated that the centrifugal force reduces the localization; when the Young's modulus of all blades are in the tolerance of 5%, the blade-disc can regarded as an cyclic symmetry system. The study results given in the present paper have provided a variety of effective numerical methods for the study of vibration characteristics of blade, disc and the blade-disc system. These research results can also serve as a helpful guide to the vibration study of other rotating components.
