SGTC如果用变压器输出高压交流直接供电（假设变压器功率足够大）---论坛的计算公式上不是有个匹配计算----计算出来的结果是---电容不能大于那个数值是吧（这个算个临界值？）？那么是不是当电容等于这...

闲话：近几天我会将一些我对火箭内弹道（两相流模型等），燃料性能推力反算的算法（如无铝APCP的a,n值）等研究成果放到论坛上来。由于论坛的公式系统实在是用不来，所以还是打算用Word先打出来然后以图片...

虽然这个问题本身没什么好说的，但是对公理本身的独立性的证明，是个很有意义的问题。请参考欧氏几何的平行公理（第五公理）。对第五公理独立性的质疑，意外地催生出非欧几何，也推动了数理逻辑（证明论）的进步。
