了好几倍。Sony闪光灯怎样?DSLR太重了。请分享及推荐。多谢。

d*b 发帖数: 21830 | 5 看来你也不知道photoelectric和compton的区别,还以为照keV能级的x-光呢,核裂变
产生的photo/electron都是MeV的,这个能级的主要作用是compton而不是
Photoelectric, 对compton作用来说,影响HVL的主要因数是electron density而不是Z
(或者你说的“密度越大的物质体积越小越高效“)
你要去核反应堆看看就知道了,里面都是水泥墩,没你说的铅板。 |

d*b 发帖数: 21830 | 6 无知真可怕,屏蔽15Mev的photon,铅的HVL是6cm,你要屏蔽GeV level的宇宙线,根本
不是你单靠铅就能解决的。这还没考虑超过8MeV的binding energy产生的中子。 |

就是用面向对象的硬件验证语言(HVL)来构建验证环境(testbench),用matrix
driven methodology来验证逻辑设计。
这两年EE的形式一点都不乐观,LS找到的是什么公司? |

b*****e 发帖数: 14299 | 15 这个数值只是辐射屏蔽设计的指标之一,跟公众还是放射工作人员无关的。有关的是另
外一个参数,
就是NCRP里面说得设计目标,P值,分控制和非控制区域。北美这边一般都用NCRP来计
算。在设计
屏蔽时,一般都要考虑leakage和散射,而leakage一般假设就是原始能量,比如15MeV
,18MeV
等等,所以都用高能的TVL。散射的能量的确只有500keV左右,但是一般计算以后,发
现散射比
leakage少。如果少一个数量级以上,就不用考虑了。否则再加一个HVL。加铅的问题是
,铅很软,
铅很重,弄不好很容易象一滩烂泥塌下来。而且在室内会有毒性,所以要么做成三明治
一样夹在混凝
土或者钢中间,要么卯起来,裸露部分还得涂上厚厚的油漆才行,对快中子还透明,对
10MeV以上高
能机器,本身还能产生中子,最后光子挡住了,中子生成了,得不偿失。
