平方反比定律

At the risk of provoking buried math anxiety, the "inverse square law" from high school physics states that if you double the distance from the source, for example, the field force drops four-fold, not just two-fold.

冒着激起潜在焦虑的风险，高中物理学的平方反比定律表明如果你离发射源有两倍距离，那么电磁场强度将下降四倍，不仅仅是两倍。

Both of the ESD were proportional to kVp 2.2 to kVp 2.5 and were linear proportion to mAs. Inverse square law exists in the relationship of focus-film distance, FFD, and ESD. The impacts of field size and patient thickness to ESD are negligible. Optimized operating condition is chosen to improve the diagnosis rate and to reduce the patient dose. The ESD, 0.12±0.06 mGy, performing the optimized operating condition of chest x-ray examinations, is less than both values of reference doses recommended by NRPB and IAEA.

研究结果发现，入射表面剂量随操作条件而变，以相同的条件照射，三相位X光机所造成表面剂量大约是单相位X光机的1.9倍；入射表面剂量与kVp的2.2至2.5次方成比例，与mAs约成线性正比，与焦斑至底片距离的关系大约符合平方反比定律；照野面积及身体厚度虽会影响表面剂量的大小，但其程度远低於kVp及mAs的影响。

In college,my friends and i came up with an inverse-square law.
