Firstly,based on the B.Bowermans result about the rate of convergence in Cesaro sense of certain nonhomogeneous Markov chains which the transition matrices converge,we are to study a certain nonhomogenous Markov chains which the transition matrices average converge to a period strongly ergodic stochastic matrice,and control the average convergenc rate of transition matrices,then we get the rate of convergence in Cesaro sense about the nonhomogeneous Markov chains by used the character of norm and the character of nonhomogeneous Markov chains.It is an extension of a B.

There was a stable and relatively low expression level for Lbα1 and a progressive expression pattern for Lbα8 among the 1st,2nd,3rd,and 4th nymphal stages.5 Development and reproduction of L.decolor as a function of temperatureThe developmental rate,survival,intrinsic rate of increase,net reproductive rate(R_0),mean generation time,and population doubling time of L.decolor population were evaluated at eight constant temperatures.

Lb a1在1龄、2龄、3龄、4龄若虫及成虫中的表达水平分别是Lb a8的2.03、2.55、4.77、6.54、和5.28倍，且它们之间的差异均达到显著水平(P＜0.05)。5温度对无色书虱发育和繁殖的影响通过比较无色书虱在不同温度条件下的发育速率、存活率、内禀增长率等生命参数以明确无色书虱在不同温度条件下的发生发展规律。

Based on the national tenth five magnitude project — Suzhou City Water Environment Improvement and Synthesize Demonstration item, we carried out the static simulation test and the dynamic simulation test under the condition of heavy pollution loading rate and low transparency and dissolved oxygen in polluted river of suzhou ancient city district. These investigations were on the base of the formers' work. We analyzed the purification effects and rules of plant floating-bed technology on polluted river water, and also applied the technology to purify the polluted river water in Miaojia River. Conclusions were summed up in the following:The dominance plant option test was carried out among Oenanthe javanica, Lolium mutliflorum and Allium sativum under low temperature condition. The results showed that the Oenanthe javanica was the dominance floating-bed plant under low temperature condition. Its net removal rate of TN、 NH_3-N、 TP、 COD_ were 51.3%、 65.2%、 55.6%、 57.6%, respectively, and inhibition rate of algae reached 92.3%.
