started with the analysis of characteristic parameter of the successive detection logarithmic amplifier,mainly discusses the main factor affecting its transfer characteristic by mathematics reasoning to its transfer function,studies the correlative relations of the single stair′s plus,the series with the dynamic range and the logarithmic precision by matlab and matrixx simulation.so two pieces of conclusion have been reached:one is on condition that the dynamic range is limited,the more the series that is used and the single stair′s plus is less,the higher the logarithmic precision is.the other is that using the double amplifier chain can enhance the logarithm starting point,so its stability is improved.and the conclusion has been applied to the practical circuit′s analysis of the tacan beaconing receiver.

摘 要：从分析连续检波式对数放大器的特性参数入手，对其传输函数进行了数学推导，重点讨论了影响其传输特性的主要因素，通过matlab和matrixx仿真，研究了输入动态范围与级联级数、单级增益和对数精度的相互关系，得出了两点结论：一是在限定动态范围的前提下采用的级数越多其单级增益越小而精度就会越高，二是采用双放大链结构可以提高对数起点，从而提高其稳定性。最后将结论应用于塔康信标接收机实际电路的分析中。关键词：对数放大器；连续检波；塔康信标；对数精度

When a first-year MBA student asks at Carnegie Mellon's Welcome Week whether the priority should be grades, academic performance or the job hunt, Greg Shumavon, a second year moderating the event, interjects before the professors can respond."The first priority should not be a two-year business programme but your partner, who is potentially for life."

在卡耐基－梅隆大学的迎新周上，当一名一年级学生问道，今后重点应是成绩、学术表现还是找工作时，主持这一活动的二年级学生格雷格·舒马文抢在教授前插嘴说：&重中之重不应是两年的MBA课程，而是可能要陪伴你一生的伴侣。&

This dissertation redefined "the mung bean rock" by synthesizing the correlation sections, according to the new congnition that the middle formation of Lei〓 in the middle region of Sichuan is the same as that of Jia〓 in eastern Sichuan Basin, the section of the Leikoupo Formation was redivided into Lei〓, Lei〓, Lei〓 and Lei〓 sections.
