3种麻醉方法的恰当选用，更能发挥各自优势及处理好病情与安危问题。

Polarization encoding is a novel format and has more advanges such as natural power equalization, better polarization characteristics,less power penality,and so on,which can greatly reduce the nonlinear effects,suppress the PMD,and improve the spectrum efficiency,so its realization will accelerate the development of high-speed fiber communications.

偏振编码是一种全新的编码格式，它具有天然的功率均衡性、偏振特性好、功率代价小等优势，可大大降低系统中的非线性效应、抑制偏振模色散、降低误码率、提高谱效率，因此偏振编码通信的实现将推动高速光纤通信更快地发展。

The presumption that new technology about distillation column with a single reactor can be used in photochlorination of acetic acid is first proposed in this paper. The fact that reaction distillation has obvious advantages in the number of theoretically perfect trays and energy consumption was obtained by theoretical analysis between the coupling of reaction and distillation and the independent operation, which lays a theoretical foundation on the application of the distillation column with a single reactor in photochlorination of acetic acid.

本文首次提出了将背包式反应精馏耦合技术应用于乙酸氯化反应的设想，通过对反应精馏耦合和反应精馏独立操作两种情况进行理论分析，发现反应精馏耦合在理论板数、能耗方面均具有明显优势，因而为背包式反应精馏应用于乙酸光氯化反应奠定了理论基础。

相对于其它利用激光诱导等离子体及空化作用等光机械效应碎石的脉冲激光碎石机，钬激光碎石机具有较大的优势，必将成为输尿管结石的一种重要的治疗手段。

Phyllanthus emblica is one of the dominant species distributed in dry-hot valleys of southwestern China. Besides its function in ecology, environment and reforestation, it is also an important medicinal plant.

余甘子是我国西南干热河谷地带的优势植物，也是一种重要的药用经济植物，对其遗传多样性进行研究对生态环境的建设和恢复有着重要意义。

Thus, the molecular techniques are becoming more popular in the differentiation of Microcystis.16S rDNA, 16S-23S rDNA ITS and PC-IGS have been used in phylogenic classification of Microcystis, they are common molecular markers of taxonomic researches and a number of results have been carried out.

利用分子生物学技术鉴定微囊藻的种属具有快速而且可靠的优势，因此已成为了分类研究的新趋势。16S rDNA、16S-23S rDNA ITS、PC-IGS等基因序列在微囊藻的分子系统发育方面已有一些研究结果，是目前分类学研究较常用的分子标记，但各自仍存在了一定的问题。

The results indicated as below: 1.The total latent infection rate and infection rate of two major fungi(Alternaria alternata and Fusarium sp)was reduced effectively with preharvest BTH treatment . The latent infection rate decreased with increasing of spraying times.Results showed that the four times of treatment by BTH is the best.

结果表明： 1。采前BTH处理有效地降低了果实生长发育期间的总潜伏侵染率及两种优势病原菌(Alternaria alternata和Fusarium sp)的潜伏侵染率，控制效果随处理次数的增加而提高，以100mg/L BTH处理4次效果最好。
