用非介入法检测诊断X射线机的管电压和曝光时间

Effect of exposure time on atmospheric scintillation of uplink beams

曝光时间对上行传输光束强度起伏的影响

The basic principle is that for exposure changing the transmissivity τ is equal to changing the exposure time t .

利用改变曝光时间t和改变透射率τ对曝光量的改变是完全等价的这一原理,不用借助任何标准密度灰片校准,可在大面积上足够精准地测量物体透射密度。

Based on the analysis of the mechanism of the thermal propagation and equilibrium, the relationship among temperature rise, thermal damage and exposure duration was deeply discussed.

在激光辐照下生物组织的热传输和热平衡机理分析的基础上 ,深入讨论了被作用靶组织产生的温升、热损伤和激光曝光时间三者之间的相互关系 ,随着吸收的光能量的增加 ,热源扩散使得靶组织的温度升高 ,温升分布将由一个δ函数扩展为一个正态分布 ,同时 ,温度升高又伴随着不同程度的热损伤。

The principle of exposure duration calibration is formed by adjusting exposure duration and keeping other parameters of digital color camera.

仅改变曝光时间,保持相机的其它参数不变,建立了曝光标定原理。
