the second chance, i know one is not a joker. if i pick, my chance is

发帖数: 20570 | 27 Although this line offers better chances, the expected value is actually
quite low.
4-0 with JT on side is only 5%. Suppose you play DA and it is indeed 4-0,
you have to take two losing finesses to go down. If you take finesses
against LHO, the chances to have at least one working finesse is very very
high. My rough estimation is about 90% of times, you should be fine (because
LHO holds a D void, also because of the lead and bidding) . That means

Suppose east holds DA, he has stiff C, he would return C here and look for a

发帖数: 642 | 29 Yes, not covering HQ is wrong most of time. So I think it is reasonable to
think RHO has no HK if not covered. (50% HK onside)
Then after LHO is in with HK, it is also reasonable to assume he will not
play C if he has CK. Otherwise he should play C no matter what he has in C.
So if he gives sluff and ruff, we will try to drop his CK. (chance 1/12).
This ends up the total chance of 54%.
At this situation (HK off), the CQ method can still make if LHO has CKxx.

出现超大剂量的核物质泄露，对几千公里公里以外的人的生理影响是极为有限的，所以
对核泄漏事件不用恐慌。
现在说正题。
现在人类投入商业使用的核反应堆统统都是裂变堆，以放射性重元素物质铀，钚，钍为
核燃料，这些核燃料都是对人体有强烈危害，并可以致人死亡的。裂变堆按照慢化剂分
类，又可以分为轻水堆，重水堆和石墨堆。轻水就是普通水。轻水堆又可以分为沸水堆
和压水堆。
沸水堆只有一个循环回路，简单说就是核燃料发热后，纯净水被注入反应炉，被加热以
后变为蒸汽，随后通过管道推动汽轮机转动，带动发电机发电。沸水堆中的压力大约在
70个大气压左右。

压水堆则有两个循环回路，核燃料首先加热第一回路中的冷却剂，随后冷却剂通过第一
回路和第二回路之间的热交换器，把能量传给第二回路。第一回路的冷却剂随后又回到
