6 S @$ m. c, k, J% F( {1 RPSPICE is a circuit simulation program that's used to pro-vide a reasonably detailed analysis of circuits containingactive components such as bipolar transistors, field ef-fect transistors, diodes, and op-amps. PSPICE can alsohelp characterize lumped components like resistors, ca-pacitors and inductors.
: {- Z2 f! W- t4 h9 Z# P( XPSPICE是一个电路模拟程序，用于对包含双极晶体管、场效应晶体管、二极管和运算放大器等有源元件的电路进行合理的详细分析。PSPICE还可以帮助表征集中元件，如电阻器、快起搏器和电感器.
; R! V$ G* q( ~8 w2 H2 K7 ~PSPICE programs are comfortable with measure-ment parameters like Voltage and Current. However,when it comes to modeling optoelectronic componentsthe PSPICE program does not possess the capability toevaluate or simulate components with outputs mea-sured in radiometric or photometric units like Watts (w)or Lumens (lm), or other variables like optical intensity,radiant power，irradiance with unit measurements inmW/sr, mW/m2, lumens./ Q; s; g- D# z
PSPICE程序对电压和电流等测量参数很满意.然而，当涉及到光电元件建模时，PSpice程序不具备评估或模拟以美国瓦茨(W)或Lumens(Lm)等辐射或光度单位或其它变量如光学强度、辐射功率、单位测量的辐照度(mW/sr、mw/m2、lumens)来评估或模拟元件的能力。
