All kinds of these study results, including analyzing the nucleotide composition, the amino acid composition, the nucleotide diversity, the synonymous and the nonsynonymous, the transition and the transvertion, the frequencies of the codon used, the construction (including four stems and four loops) of tRNAleu,the phylogeny,suggest that great distinctness present among the genera and small difference even none among species.

在各种分析中(包括核苷酸基本组成分析；氨基酸基本组成分析；核苷酸多样性分析；非同义替代和同义替代分析；密码子使用频率分析；转换与颠换分析；tRNAleu基因的四臂四环二级结构分析；&翻译启始&和&翻译终止&在进化过程中的变化；系统发育分析)，属间的差异相当明显，而种间差异很小甚至是没有任何不同之处。

It utilized factor analysis and regression analysis ofthe multi-statistics to make the quantitative analysis on a great deal of core proxies in the North Indian Ocean and Indonesian Archipelago areas, and acquiredthe exact conversion relations of paleoceanic environment parameters (sea surface temperatureand salinity) and proxies. Then it made the change curve which can show the changes of paleo-ceanic environment parameters (sea surface temperature and salinity) which followed the changesof depth and provided the contrast between paleoceanic environment parameters of different coreson the landscape orientation. This paper supplied a more scientific and exact method for resumingthe paleoceanic environment on paleoceanography research.

本文阐述了以古海洋学数据库系统数据为基础的古海洋学多元统计分析模型，利用多元统计学中的因子分析和回归分析技术对北印度洋以及印尼多岛海地区大量岩芯的替代指标做定量分析，求出古环境参数与替代指标的精确转换关系，从而做出各岩芯处古环境参数随深度的变化曲线，提供不同岩芯在横向上的古环境参数对比，为古海洋学研究中恢复古环境提供了一种更科学更精确的方法。

In trial 2, according to the similarity of calving date and milk yields, 25 primiparous Holstein cows were divided into five equal groups in a randomized block design with 49 days period. The general diet of dairy farm was fed to cows of control. The alfalfa block 2.7kgd^(-1 was substituted respectively by rice straw block Ⅰ,Ⅱ,Ⅲ or Ⅳ as treatments.

试验2，选取25头初产荷斯坦泌乳母牛采用随机区组设计按产犊日期、产奶量一致原则等分为5组，对照组用奶牛场常规日粮饲喂，试验Ⅰ、Ⅱ、Ⅲ、Ⅳ组分别用稻草块Ⅰ、Ⅱ、Ⅲ、Ⅳ等量替代苜蓿草块，每头替代量为2.7kgd^(-1)，试验期49d。

When researching the producer's behavior,such as factor input and output efficiency,using product function or cost function,researchers frequently ignore the economic inefficiency and assume that the productor can attain the production possibility frontier.

通常采用生产函数或成本函数研究生产者行为时，一般默认生产者总是在生产可能性边界安排生产，而忽略了由于产出的经济无效率所造成的偏差，这种偏差最终会影响要素替代弹性、要素最优配置及产出效率的准确测度。本文采用面板模型的三要素成本函数循环参数估计法，通过施加规模报酬不变的假设，估算了辽宁省工业部门二类行业的相对技术无效率、配置无效率程度及要素间的相对价格扭曲，并计算了资本、劳动、能源要素间的交叉替代弹性。

It is necessary to carry out a thorough study on pest control technology with DMDS, with an expectation of obtaining a new fumigant of methyl bromide alternative.2. Investigation of the toxicity of fumigation on adult and mixed stages of the three most tolerant insect species -- Sitophilus oryzae, Rhyzopertha dominica and Tribolium castaneum -- under a range of EtF、DMS and DMDS doses in a Flow-through Fumigation System shows that the FTFS procedure offers a constant concentration of fumigant with low CO2 concentrations and ensures that the fumigant toxicity is effectively not compromised by CO2. In comparison with chamber fumigation method, the toxicity data of EtF、DMS and DMDS obtained from this experiment is more accurate by using FTFS.

主要研究结果如下：1、甲酸乙酯和二甲基二硫对仓储害虫具有良好的控制作用，应加快甲酸乙酯替代溴甲烷防治仓储害虫开发应用，同时，二甲基二硫是很有潜力的仓储害虫防治熏蒸剂，要深入进行二甲基二硫控制有害生物的技术研究，以期获得新的溴甲烷替代熏蒸剂。2、利用循环熏蒸系统测定了甲酸乙酯、二甲基二硫和甲硫醚对米象Sitophilus oryzaeL。

Based on the shortcomings of the COD determination method revised in National Standard, some improvement measures of the standard method, including improvement of slaking phrases, research of substitution catalysts and elimination of chlorine ion disturbance, are compared and discussed. Afterwards, some common substitution COD determination methods, such as correlation coefficient analysis method, electrochemistry analysis method, spectrophotometric analysis method and flow inject analysis method, are introduced.

在论述了国标中COD标准方法不足之处的基础上，本文就标准方法的众多改进措施分类进行了比较与探讨，包括消解方法的改进、替代催化剂的研究以及氯离子干扰的消除，然后介绍了相关系数法、电化学法、分光光度法和流动注射法等COD测定替代技术。
