双语例句
- Assuming that the detection efficiencies for a-particles of different energies are equal when the distances between the detector and the source are zero, we can calculate the detection efficiency of radon daughter for one standard source on the basis of radioactive decay law.
假定源与探测器距离为零射，探测器对各种能量α粒子的效率均相同，则根据放射性衰变规律，由对标准源的效率就能计算出氡子体的探测效率。
