If you are ambitious, try this alternative procedure: note that f'(x)involves the heaviside stepfunction . 如果你有雄心的话,可以用另外步骤试之:注意f’(X)包含亥维塞阶梯函数。
They varied both chamber pressure and mixture ratio, making use of a stepfunction change in the oxidizer injection rate . 他们通过用氧化剂喷射速率阶跃函数变化的方法来改变气室压力和混合比。
