There was the same horizontal distribution for the abundance and biomass of ostracods in 9 sampling areas, and then the high abundance and biomass appeared in the east of Tai Lake (such as East Tai Lake, Eastern Coastal Belt and Gong Bay) because of the feeding and behavior habits of ostracods. Among the 9 areas, except for Meiliang Bay and Gong Bay, there was similar seasonal pattern for abundance and biomass in Tai Lake.

fabaeformis和塔尔薄丽星介的自身繁殖力是造成梅梁湖和贡湖中介形类丰度和生物量间存在差异的主要原因，但两湖区中介形类丰度和生物量在整个太湖中所占比重有限，所以不影响太湖总体介形类季节变化趋势，四个季节中介形类的丰度和生物量均值总体呈现出秋＞夏＞冬＞春的规律。

In our country's present railway system,the diesel locomotive occupies biggish proportion,especially in the northern area of our country,which increase more cost because of using high-grade diesel oil in winter.

0引言在我国当前的铁路系统中，内燃机车占有着相当的比重，因内燃机车在使用过程中所消耗的燃油是随季节变化而变化的，尤其是在北方地区，夏季采用0号或10号柴油，而冬季则要采用-20号甚至-30号柴油，因此，成本要增加很多。

31DH suspend in the dry red wine and ferment,the density of the dry immobilized 31DH was changed by various materials.

通过选用不同的材料调节干固菌胶粒的比重，使固定化酒类酒球菌31DH悬浮于干红葡萄酒中进行苹果酸—乳酸发酵，并测定这些材料对固定化胶粒相对扩散系数的影响。

By field and indoor test, the paper measures soil physical property, soilmoisture constant and soil water movement parameter, provides the soil specificgravity , the soil apparent density, the soil fraction, the soil field moisturecapacity, the soil saturated moisture capacity, the soil percent moisture content ofcom germination and seedlings emergence, the corn wilting point, and alsoestablishes the equation of soil water retention curves, the equation of soil waterdispersion coefficient and the relationship between pressure and soil apparentdensity, and so those provides the parameter for numerical simulation.

通过田间和室内试验，测定了供试土壤的物理性质、土壤水分常数和土壤水分运动参数，得到了该土样的比重、容重、机械组成、田间持水率、饱和含水率、玉米种子发芽出苗土壤含水率、玉米凋萎系数，给出了土壤水分特征曲线方程、土壤水分扩散系数方程及土壤容重与土壤压紧力的关系，提供了数值模拟过程中所需的参数。

Through strengthening natural forest conservation and nature re-serve management, continuing key eco-protection projects, establishing important ecosystems, and stepping up natural ecological restoration, by 2010 some 90 percent of typical forest ecosystems and key national wildlife species will be under effective protection; nature reserves will account for 16 percent of the national territory; 250,000 sq km of land suffering from water and soil erosion will have been improved; 300,000 sq km of land will have been ecologically restored; and 22 million ha of desertified land will have been put under control.
