发帖数: 52 | 1 看到的IM3例子都是两个single tone的正弦波（f1,f2), 那么三阶交调是2*f1-f2, 和2
*f2-f1。
但是如果是宽频信号，比如(f1L~f1H,和f2L~f2H),那么他们的三阶交调是不是(2*f1L-
f2H)~(2*f1H-f2L) 和 (2*f2L-f1H)~(2*f2H-f1L)了？ |

for im3, i think there is a 6db or sth relationship. get a RF book. they
have the derivation on it. |

因为结了婚的缘故，所以现在基本是没可能去看凌晨的首映了，于是买了早上第一场的
IMAX，睡眼惺忪的就冲到电影院去了，因为IRON MAN3，是绝对不能错过的片子。这次
依旧废话不多说，直接进入正题，以下大量剧透，观者自酌…
其实在复仇者联盟的众多超级英雄中，STARK是我最喜欢的一个，倒不说他是万贯家产
的高帅富，更加因为他是一个真正意义上的凡人英雄，和那个只会抡锤子的雷神完全不
在一个档次上啊！正因为是凡人，所以才有喜怒哀乐，才有愤怒和恐惧。IM3正是延续
复仇者联盟的剧情，讲述了STARK在经历了纽约一战后患上的焦虑症以后的事情。我记
得在前面的片子里面有人也问过STARK：“到底是你成就了IRON MAN，还是IRON MAN成
就了你”。现在，STARK一样想搞清楚这个问题。
和诺兰的TDK系列不同，IRON MAN3虽然同样在讲述一次自我救赎的过程，但片子拍的并
不会太过阴暗，因为STARK的犯贱是影片的亮点之一，在本片中同样不会缺少。当然还

发帖数: 24887 | 13 个人觉得如果一定要选一个,还是喜欢STID多过MOS那么一点点. 但是实在不觉得应该在
这二者之间选择.也许在MOS和IM3之间选择更公平一些.
注: 我是极爱Superman的,而且承认MOS比79年的Superman要更好看一些,但是也许物是
人非,MOS代给我的震撼或者感动不如当年的超人.但是仍然还是非常值得一看. |
