count rate

基本解釋

The effect of high potential and gas proportion on the count rate and the energy resolution was discussed in detail.
討論了高壓和氣體比例對探測器計數(shù)率和能量分辨率的影響。
Water-flow velocity of continuous measurement was determined by the ratio of count rate value of different source spacing detectors.
連續(xù)測量的水流速度是通過不同源距探測器計數(shù)率的比值來確定。
The count rate at the extrapolation of bias to zero varies monotonously with the anode current of phototube and tends to the activity of source as the inverse anode current approaches zero.
甄別電壓外推到零時的計數(shù)率隨光電倍增管陽極電流而改變，當(dāng)陽極電流的倒數(shù)趨于零時，計數(shù)率趨于被測源的活度。

If he switched from gold to let's say iron, he also tried platinum, a number of different foils, he found that they count rate it still was 20 alpha particles per minute.
金箔的時候，計數(shù)率就變成零了,如果他把金換成比如說鐵，他們還嘗試了鉑,還有一系列其他的箔片，他發(fā)現(xiàn)計數(shù)率還是每分鐘。

And, of course, all that's left is this positive pudding. So that's not going to do anything either. And what he found when he did this experiment, was that the count rate with still 132 000 counts per minute.
剩下的是帶正電的布丁,也不會產(chǎn)生什么影響,結(jié)果他實驗上觀測到,計數(shù)器測得每分鐘132000下,所以到目前為止,他可以說實驗。

And no, it wasn't. When he took away the gold foil the count rate went down to zero.
看看是不是從,其他地方打進來的alpha粒子,但不是，當(dāng)他拿走。

R-count, to a rate that has previously always signalled that a recession had started.
