最佳管距对应的管束水力当量直径近似等于池内沸腾时的气泡脱离直径。
The optimum tube spacing equals approximately to the departure diameter of the bubbles during a pool boiling.
两相流流型分类的直观物理几何意义在于气泡空间尺度（相对于流道水力学当量直径）及其分布。
The flow regime of two-phase flow is straightly and physically charaterized by the size of gas bubbles relating to pipe diameter and the distribution of gas bubbles.
