It is proved that the uniform density hypothesis is the sufficiency condition for the proportionalexpansion hypothesis under the existence of the breech boundary motion and the mass jet.
同时，证明了存在膛底边界运动和质量加入条件下的拉格朗日假设是比例膨胀假设的充分条件。

Second, the initial point and transfer time are same for different object relative orbit, and the minimum consumption of fuel is proportional to the expansion deflection.
不同膨胀系数时施加脉冲的时刻不变，最优的燃料消耗与膨胀变化量成正比；
3
The release of BNP is directly proportional to left ventricular pressure and volume expansion.
