critical diameter

In this paper, according to one-dimension flowing theory of ideal gas, calculation formulas of critical backing, pressure and diffuser throat diameter of oil vapour pump are introduced, and then some methods of improving critical backing pressure are discussed.

本文根据流体力学理想气体一维流动的理论，导出了油蒸汽流泵的临界前级压力和扩压器喉部直径的计算公式，并且讨论了提高临界前级压力的措施。

Furthermore , the larger diameter of case rear aperture is, the greater critical buckling load is.

壳体后开口直径越大, 临界屈曲载荷越大.

It was found that with a size ratio higher than the critical value the particles with larger diameter cannot form ordered close-packed basic lattice, and as a result the corresponding binary colloidal crystal had a low degree of order, which was in accordance with previous literatures.

实验证明，当微球粒径比高于该值时，大球将无法形成具有密排有序结构的基本点阵，所得二元胶体晶体的有序度很低。这与现有文献报道一致。

Through a study of the separation characteristics of a mist eliminator in a wet desulfurization system the following two concepts are defined, namely, critical separated droplet diameter of a mist eliminator and critical captured droplet diameter by a cylinder.
