指出在瞬态信号激励下，必须用严格的夫累涅尔-基尔霍夫公式来计算辐射场，否则将丢失许多重要的瞬态特性。
Under the excitation of an impulse, the radiation field has to be evaluated in terms of precise Fresnel-Kirchhoff formula; otherwise, some important transient features would be lost.
提出了一个新的化学反应热计算式，该计算式不仅能对非等温反应的反应热进行计算，而且还可克服应用基尔霍夫公式不能有相变化的限制；
A new formula to calculate reaction heat is put forward. It is suitable not only for isothermal reaction, there is no limitation of phase change.
