其中a是最优的，其他三种方法是suboptimal的
想比较一下在某几个点的时候这几种次优方法的performance loss,
请问该用和表达式来表达各种方法的performance loss?
比如：-10*log(b' ber/a's ber)
还是：-20*log(b' ber/a's ber)
or -*log(b' ber/a's ber)
或者其他表达式？thanks |

Ni is much smaller than your particle size. then the difference between the
bulk and the powder would be small. However, the bigger the sample is, the
bigger your domain tend to be. so, i would say the hysteresis loss would be
different. |

登陆账户以后发现我还剩的一点BPFH以5.73成交了。但是看了看今天最低也就到过5。
71啊。于是打电话询问，一个转一个的，终于有人回答我说因为今天早上开盘时的bid
价低过我的stop loss,所以我的order就被trigger了，虽然最终那个bid价并没有真正
成交。还说他最近碰到两次这样的事情。我问他怎么避免这种事呢，他说没什么办法，
不过这些都倾向于发生在low volumn的股票。
昨天盘后BPFH价格是比较低。我一直以为是交易价trigger stop loss order的，看来
