多重点

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

Women also face many social and emotional challenges, which can lead them to become a slave to the scale, avoid exercise for fear of bulking up and fall for spot reduction and quick fix solutions, all of which only compound the problem,婷美上海婷美实体专卖店,郑州婷美专卖店, These fears, misconceptions and bugaboos, which hold so many women hostage, could easily fill a book, but let's skip over all that and talk about solutions that DO work.

女性经常面对来自社会和感情方面的困扰从某种程度上说这使得她们更难以摆脱如同奴隶的命运般的困境她们畏惧体育锻炼她们担心这些体育活动会使她们的腿部变粗胸部变小因而她们倾向于寻找快速而容易的塑身手段然而这将带来更多的问题恐惧误解以及如同幽灵一般的错误认识就象挟持人质的案犯一般控制了女性的思想和行为这几乎可以写成一本完整的书籍让我们揭开它们的面具还原它们的真实面目下文将重点讨论解决方案以及从现在开始改变对就是从现在。

In 50 years' time, i believe people will look back and wonder what the hell we were thinking desecrating our land and oceans like we do. We need to change our priorities, there's too much emphasis on growing the economy through short-sighted, short-term gains, with no thought given to the long-term effects.

在50年的时间里，人们会回顾和质疑我们究竟在想什么这样去亵渎我们的土地和海洋，我们需要去改变我们的重点，这里太多强调用短浅的目光，最短的时间去发展经济，而没有长远的打算。
