We also present the sufficient and necessary condition of the laws of logarithm, and we extend Teicher-type strong law of the large numbers for sequence of NA random variables.

Using augmented Dickey-Fuller test, the result shows that BDI logarithm series is nonstationary but the first difference is stationary, i. e. it is integrated of order one. High-level ARCH effect was certification in the BDI logarithm series by ARCH LM test, and GARCH (1, 1) model was used to eliminate the conditional heteroscedasticity. Through variance ratio test, the result shows, that the random walk hypothesis of BDI logarithm series can be rejected and international dry bulk shipping market is inefficient.

And the conditions in cell suspension culture of Mikania micrantha were studied. The results showed that sucrose was the compatible carbon sucrose, and 30g/L sucrose concentration can satisfy the growth of Mikania micrantha cell; ammonium was absorbed under different sucrose concentration that haven't demonstrated significant specificity, and was completely absorbed on the lag phase and the early logarithmic phase; while nitrate was mainly absorbed on logarithmic phase. The density-dependent of Mikania micrantha cell starting to grow and density-inhibited of cell growth were proposed, the fittest inoculating quantity of Mikania micrantha in cell suspension culture was 40g/L.
并对微甘菊细胞悬浮培养条件进行研究，结果表明，微甘菊细胞生长适宜的碳源是蔗糖，并且较合适的蔗糖浓度为30g／L；在不同蔗糖浓度下氨基氮的吸收差别不大，氨基氮在迟滞期和对数期前期已基本消耗完毕，对数期生长主要利用硝基氮，因而提出，在微甘菊细胞液体悬浮培养中，氮源可以采用初始低氨基氮浓度，对数期中间维持高硝基氮，而且对数期中逐步流加少量的氨基氮；微甘菊细胞迟滞期分裂启动存在密度依赖现象，对数期生长存在密度抑制现象，最适接种量为40g／L。

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
