The influence of sterilization temperature, time and electric voltage of ohmic heating on the survival rate of the bacteria counts, coliform and nutrient components were investigated and compared with traditional pasteurism. The result showed that the bacteria counts and coliform were equally decreased with the increasing of sterilization temperature, time and the voltage of ohmic heating, but the nutrient component loss were elevatory after the same treatments.

蛋白质含量是评价稻米品质的一项重要指标，控制水稻糙米蛋白质含量的基因位点是数量性状，检测水稻糙米蛋白质含量的QTL并进行遗传效应分析对于水稻品质遗传育种具有重要的意义。

Four 20kg six-month old goats with permanent remen cannula were used to study the effect of three kinds of urease inhibitors acetohydroxamic acid, hydroquinone, yucca extract on nitrogen metabolism, nutrient degradability in rumen and nutrient digestibility.

本研究由4个试验组成，选用安装永久瘘管的6月龄山羊4只，采用4×4拉丁方试验设计，分别饲喂对照组饲粮、乙酰氧肟酸25mg／kg饲粮、丝兰皂甙36mg／kg饲粮、对苯二酚40mg／kg饲粮。

Avian embryo normal growth and development depends on all necessary nutrient from Avian eggs .As Romanoff （1972） pointed out, nutrition is critical ,no matter how deficiency or over-dose of nutrient ,It both leads to all kinds of nutritional defect ,even mortal stress .

禽胚的正常生长与发育取决于蛋提供的所有必需的营养物，Romanoff等(1972)指出，营养为本，无论是缺乏还是过量均会使胚胎出现各种营养性缺陷甚至于致命的应激。

In this paper, as a case of Karamay, we have studied on space-time changement of soil quality in oasis of arid area. We measured quality for different land use types and years in same type by combinativing field sampling for Karamay in Xinjiang and analysis in laboratory, which is directed by former theory of soil quality. Then we did integrated evaluation of soil quality for different land use types, and had drew some conclusions as followed: In four land use types, the soil bulk density of layers(0～15cm) for farmland and tree land is bigger than the other land use types.The organic matter of every layer in manpower Tamarix Bulrush land is bigger; organic matter of Tamarix Bulrush land release efficiency nitrogen which result ration of C/N is higher; total nitrogen of all layers in farmland variety great as being effected by mass use of nitrogen in agriculture; deadwood and defoliation of tree、shrub and bulrush pooled in 5cm layer to result that quick nitrogen is the biggest among all layers. The total salt of nature shrub tree land for every layer being bigger than farmland explain that nature shrub thee land strongly stand salt and farmland for basification in this area; that the nutrient of face layer is bigger than the ground layer may be explained by that vegetation gather nutrient to be stored in deadwood and defoliation.

本文对以克拉玛依为例，对干旱区绿洲土壤质量的时间空间变化进行研究，在有关土壤质量的研究理论指导下，通过田间调查取样和室内分析相结合的方法，对新疆克拉玛依市农业开发区的不同土地利用方式及同一土地利用方式下不同利用年限土样土壤理化性质进行测定，从而对新垦绿洲不同土地利用类型土壤质量进行综合评价，结果如下：四种土地利用方式中，农地、乔木林地表层(0-15cm)土壤容重较大；各土层人工柽柳芦苇地的土壤有机质含量均较大；柽柳芦苇地的有机质在矿化过程中所释放出有效氮，导致柽柳芦苇地的C/N比例较高；受到农业耕作使用大量氮肥的影响，农地各土层全氮含量变异较明显；乔木、灌木及芦苇的枯枝落叶主要集中在5cm范围之内，导致几种土地利用方式类型下该层土壤速效氮最大；天然灌木林地的土壤总盐在各层均较大，其次是农地，说明天然灌木林地的高耐盐能力，以及该区农业生产用地的土壤盐碱化程度较重。

There had been a moment during the breakfast meeting, though, after the backslapping and the small talk and when all of us were seated, with Vice President Cheney eating his eggs Benedict impassively and Karl Rove at the far end of the table discreetly checking his BlackBerry, that I witnessed a different side of the man.
