After verification of the program, the mathematical models of the suspension bridges were studied by means of the program, as well as the determination of the main cable's shapes and its internal forces at different stages, the calculation of the cable's unstrained length and the analysis of the construction processes, of which some new approaches were presented in the mean time. Thus makes the structural analysis results of suspension bridges more reliable and in accordance with reality.

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

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
