计算更改速度 - Count rate meter
计算速度测定器 - Counting rate meter
计数率计 - Event count rate
事件计数率 - The results of numeral simulation show that the higher - energy neutrons counting rate is quite low , it requires more counting time or much stronger low energy neutron source to detect the reliable signals
计算结果表明，核弹头裂变产生的较高能的中子数很少，需要较长的时间或较强的低能中子源才能探测到可靠的信号。 - If using the natural uranium to replace the heu pit in warhead , the delayed neutron counting rate would be about 3 times lower . the coincidence neutron detection is proposed to be used in nuclear warhead detection
计算表明用天然铀替代高浓铀作的假弹头，它们的出壳缓发中子数相差约3倍，需在一定条件下，才可对真伪核弹头做出判断。 - In experiment , the alignment and calibration to the monochromator were described firstly . then , a gas - flow proportional counter and the multi - channel analyzer ( mca ) are calibrated by the radio isotope source 55fe , and the dead time , counting rate plateau and x - ray linearity have been measured
最后利用同步辐射光源做激发源，在掠出射方式下研究了si片上不同厚度单层cr膜和双层fe v膜样品产生的荧光光强和掠出射角的对应关系。 - That the common amplifier count rate is low , temperature voltage drift is very good , the machinery adjustment is rough and instability , in order to overcome these shortcomings ; we use digital potentiometer relay x9511 and precise operational amplifier op37 , the electric circuit structure become simple
为了克服一般放大器计数率低,温漂大,机械调节粗糙不够稳定等缺点,使用了非易失性数字电位器x9511和精密运放op37 ,使电路结构大大简化。 - The results show that coincidence detection method has obvious benefit in detecting nuclear warheads . for the same type warhead , the coincidence counts rates of the model of warhead of heu pit is 10 times as big as that of fake warhead of natural uranium pit . if we know the nuclear warheads configuration by other methods , the method of coincidence neutron detection could be used to distinguis h the fake nuclear warheads from the reals
计算表明用探测符合中子的方法探测核弹头对区分真假核弹头有明显的优点，对于同一核弹头模型，裂变弹芯是高浓铀和用天然铀替代高浓铀时，符合中子计数相差1个量级，如通过其他途径了解核弹头的大致结构，符合测量的方法就可以有较高的置信度分辨真假核弹头。
