型砂韧性和流动性在粘土砂中是互相对立的，它使Y2机座表面质量和成品率不能兼顾。
The surface quality of Y2 frame and the percentage of end product can not be compatible, because the toughness and mobility of the moulding sand in clay sand are antagonistic each other.
空泡率是汽液两相流动的基本参数之一，而已有过冷沸腾空泡率计算方法研究以高质量流速为主，且大量文献报道现有空泡率模型难以适用于低流速过冷沸腾工况。
Void fraction is one of the basic parameters in steam liquid two phase flows. To date, the study of methods for calculating subcooled boiling void fraction mainly focused on high mass flow rates.
