在集成电路中，通常采用T型解码网络实现数字量往模拟的转换，再利用运算放大器完成模拟电流变为模拟电压的转换。所以，要把一个数字量变为模拟电压，实际上需要两个环节，先把数字量变为模拟电流，这是由D/A转换器完成的；再将模拟电流变成模拟电压，这是由运算放大器完成的。有时D/A转换器芯片只包含前一个环节，有些D/A转换器则包含两个环节，用前一种芯片时，需要外接运算放大器才能得到模拟电压。-In integrated circuits, the usual T-decode digital networks to analog conversion, and then complete the simulation of the use of op-amp current into the analog voltage conversion. Therefore, it is necessary to become a digital simulation of voltage, in fact, need two links, first into a digital simulation of currents, this is determined by D/A converters completed then simulate current into the analog voltage, this is determined by computing completed amplifier. Sometimes D/A converter chip contains only a part before, some D/A converter includes two aspects, before a chip, the need for external op-amp voltage can be simulated.

应用背景SWAT 开源,用于水文模型的进一步开发开源，可以对源模型进行改装，增加模块和减少模块，并进一步开发，使模型更加适合研究区的状况，也可以对模型进行重新组装开发，从而节约成本，提高工作效率，为我国水文模型的开发提供便利。关键技术After excluded the influence of antecedent rainfall, the soil loss at the hillslope with ephemeral gully had a significant linear regression equation with PI30.  Since determination coefficient (R2) and Nash-Suttclife efficiency coefficient (ENS) were all satisfactory, the results showed that soil loss equations were all run well while applying to soil loss prediction for the three rainfall regimes.

该程序实现显示一个数字的方阵，程序中的清屏功能可将上次运行的结果 清除，重新显示下次运行结果。本程序在dos中或windows98中运行。-the program figures show a phalanx, procedures of the screen will be the last operation to remove a result, the next re-running show results. This procedure dos or running Windows98.
