The test points of it are dispersed on the surfaces of two spheres with same centre and different radius,so it solves the problem of rank decreasing of information matrix. It also has such advantages as fewe...

该计划在两个不同半径的同心球面上布测试点，解决了信息矩阵的降秩问题，具有试验点数少、实现方便和模型估计精度高的优点，在理论上和实际应用中均具有一定价值。

In the paper, 3D temperature and fluid flow fields were numerically simulated in three-split concentric tube recuperator with longitudinal fins on conjugated heat transfer.

数值模拟了变物性带均布纵肋的同心套管换热芯的导热和对流换热耦合问题三维温度场和流场以及Nu数，与常物性下的结果进行了对比。

The calculation of the rotordynamic coefficients of a multistepped annular seal in hydraulic turbines is discussed in this paper. Based on the Hirs' turbulence lubrication theory and the bulk flow model, the governing equations for the flow in the seal are developed by using the Moody's friction equations. The governing equations are perturbed when the rotor and the stator are coaxial. The Runge Kutta integration method and the Newton Raphson iteration method are used to solve the perturbation equations....

本文首先在Hirs紊流润滑理论的基础上，采用体积流动模型及Moody摩擦方程建立起阶梯口环水封中流体流动的控制方程，将各个方程在转子与定子同心处进行摄动，采用Runge－Kuta积分法及迭代过程求解摄动方程，建立起水轮机阶梯式口环水封的转子动力特性系数的计算方法，为水轮发电机组轴系的动力学分析提供了必要的理论基础。

A feature may be manufactured to a very tight size tolerance but due to eccentricity, the runout could be large.
