Standard practice for heat flow calibration of differential scanning calorimeters 差分扫描量热计的热流量校准标准实施规程
2.
To summarize : the reason why calibrating a lens does not damage its performance with multiple camera bodies is because the calibration standards for the lens are independent from the calibration standards for the body 简而言之，镜头的校准无损于其与多个机身配合的原因在于镜头的校准标准是独立于机身校准标准的。
