maximum safety temperature

It calculates the lowest safe height on the conditions of different aircraft attitudes and different aircraft veloci- ties.

对国产某型弹射座椅进行了分析,推导了人椅系统的运动方程,计算了飞机不同飞行姿态和速度下的弹射座椅的最低安全高度,并分析了飞机各种姿态和速度对最低安全高度的影响。

The calculating formulas about the risers minimum safety height and the volume ratio of the surplus molten steel were derived by establishing the solidification mathematical model of a riser-casting system and using the Chvorinov law involving the relationship between freezing time of liquid steel and its geometric modules.

通过建立冒口铸件凝固数学模型,利用凝固时间与模数对应关系的Chvorinov法则,推导出了冒口最小安全高度、冒口富余钢液体积比计算公式。
