The possibility of determining of chromium (III, VI) ions wa. investiga.ed in this pa.er. It is shown tha. the electrode on а ba.is of heаzlewoodite ha. high selectivity to chromium (III) ions. a.so the sta.ility consta.ts of complexes, forming in system “Cr3+-Mohr’s sa.t-Ca.OH)2-PVa.÷ Pa.” were determined by potentiometric titra.ion with ion-selective electrode.

自动增益控制（a.C）放大器利用了控制器件的非线性特征。它们的某些微分参数中的实分量大小会发生变化．这取决于它们的DC工作点的变化。一个典型例子就是硅PN结的Va.征，它导致了与通过的DC电流成正比的微分电导（参考文献1）。在这种控制形式中．主要问题是控制元件的非线性传递特征．一旦被处理的电压振幅超过毫伏级．该特征就会导致较大程度的非线性信号失真（参考文献2）。
