However, the cylindrical rotor of the rotational type viscometer needs time to respond to temperature changes in a sample.

旋转式粘度计圆柱型转子体积较大，对样品的温度变化作出的反应较为迟钝，并且还需长时间才能达到热平衡，不适于实时的测量。

Weak formulation of mixed state equations including boundary conditions are presented in a cylindrical coordinate system by introducing Hellinger_Reissner variational principle.

从Hellinger_Reissner变分原理出发，在柱坐标系中，导出圆柱壳的弱形式混合状态方程和边界条件，联用状态空间法给出叠层柱壳的解析解，此法使得求解该类问题的形式得以扩大和统一。
