The transmitted field characters of h-SIL are affected by the material dispersion with illuminating lights of different wavelengths, The resolution, focal depth, focused intensity of h-SIL are sensitive to the change of wavelength and have a periodic oscillation whh the wavelength's change.
对应不同波长的照明光,h-S1L的材料色散作用将对其透射场特性产生影响。h-SIL的分辨率、焦深和聚焦强度对照明光的波长变化非常敏感,都随着波长的变化成周期性的振荡。
The concept of safety integrity level ( SIL), safety lifecycle, the qualitative and quantitative methods of the safety integrity level selection, and how to determine the required SIL are discussed.
讨论安全完整性水平的概念、安全生命周期、安全完整性水平选择的定性、定量方法,介绍如何遵照功能安全的国际标准进行安全完整性水平选择。
