The reason is that, as mentioned earlier, Scheme will rename pi and e so they don't conflict with other names in enclosing or nested scopes.
原因在于Scheme会对pi和e 进行重命名，使它们不会与包含或嵌入宏的范围中的其他名称冲突。
Pi So as we've written it, we've got Pi of Ei exp is proportional to e to the minus Ei over kT.
就像我们写的一样，我们得到,正比于。
F(electromotiveforce) of synchronous motor is the most important interference, the general PI(proportion integration)current regulator does not retrain the effect of E.
分析了影响同步电动机矢量控制电流控制环动态特性的主要因素，指出同步电动机反电动势是其中最重要的干扰因素。
