The ammonia volatilizing of fertilizer is suit to the dynamic equation as Y=a+bt, thecoefficients in the equation are related to the kind of fertilizer, temperature and water content of soil, and the dynamic equation about ammonia volatilization including water and temperature and the is developed.

肥料氨累积挥发量符合零级反应动力学方程Y=a+bt，方程中系数与肥料种类、温度和土壤含水量有关，碳铵a、b值均比硫酸铵高，土壤含水量增大，a、b值降低，温度升高，a、b值增大，并由此得到含温度或土壤湿度因子的肥料氨挥发动力学方程，并建立了含水、热因子的肥料氨挥发水热耦合效应动力学方程。

The literature values of methane solubility in hexane at temperatures of 298.15 K, 303.15 K and pressures up to 12.0 MPa validated the precision and stability of the apparatus. The total deviation of the system was less than 2.5﹪. The method of fitting gas solubility at high pressure by Krichevsky-Kasarnovsky K-K equation was also proposed and corrected.

利用此装置测定了温度为298.15 K、303.15 K和压力2.0～12.0 MPa下甲烷在正己烷中的溶解度数据并与文献值相比较，从实验数据的精度和重复性考察了实验装置的可靠性，实验值和文献值的相对误差均小于2.5﹪，同时根据Krichevsky-KasarnovskyK-K方程提出了一种从高压实验数据回归常压实验数据的方法。

Results show that PV, KV, AV and insolubles of the RSO biodiesel increase, IV decreases during oxidation tests. The iso-octane insolubles are much higher than the total insolubles, which indicate that great attention should be paid when mixing RSO biodiesel with mineral diesel fuel.

结果表明，氧化过程中橡胶籽生物柴油的过氧化值、运动粘度、酸值、不溶物增加，碘值降低，其中异辛烷不溶物比总不溶物量大很多，对于高度氧化的橡胶籽生物柴油与非极性物质如矿物柴油混合时应引起重视。

This experiment is designed to analyze the effects of different temperatures and pH on lactic acid bacteria isolated from koumiss by improved MC culture. The OD600, pH and vaccine opacity of the culture at terminal were measured.

实验用改良MC培养基为载体，通过目测菌液浑浊度，测定菌液OD600值和培养终点时pH值，对从酸马奶中分离出的乳酸菌的生长温度及pH值进行了研究。

RESULT: The K or K of laetrile, paeoniflorin and paeonol had no significant difference at concentration of 19.2~304.8, 18.4~329.5 and 7.8~125 μg/mL respectively or in four different regions of rat intestinal tract, the absorption quantity of laetrile, paeoniflorin and paeonol was proportional to its concentration respectively and the phenomena were not observed saturable. Except for Paeonol, the K and K of laetrile and paeoniflorin had no significant difference at pH value 5.0~7.4. The K or K of laetrile and paeoniflorin from the extration which contains one kind of active components was significantly less than that of same components from GuizhiFuling Capsule content.

结果：苦杏仁苷、芍药苷、丹皮酚分别在19.2~304.8、18.4~329.5、7.8~125 μg/mL浓度范围内，吸收量与浓度呈线性关系，无高浓度饱和现象，K、K值基本保持不变；除丹皮酚外，在pH 5.0至pH 7.4范围内苦杏仁苷、芍药苷的吸收不受pH影响；3成分在各肠段的K、K均无明显差异；仅含有上述3成分中一种成分的各个提取物的苦杏仁苷、芍药苷的K、K值显著小於由配方药材提取得到的胶囊内容物的相应成分的K、K值。

Iron content of the hybrid was significantly and positively correlated with those of their female parents,male parents,high-value of parents,mid-value of parents and difference between high-parents and low-parents,and was significantly positive correlated with low-value of parents.

杂交种籽粒铁含量与母本、父本、高值亲本、中亲和高低值亲本之差的相关均达正向极显著水平，与低值亲本的相关达正向显著水平。

The valuators send the bid information to the resources entities,whether the resources entities bid according to the bid information,if the valuators receive bid applications sent by the resources entities,than they just only research trusted entities in the resources entities that they have send the bid applications,than the valuators sign the contract with the resources entities which accord with the conditions.

首先由评估者向资源实体发出招标信息，资源实体根据招标信息投标或不投，评估者收到资源实体的投标申请书，就只需在已发投标申请的资源实体中进行信任查找，然后与符合条件的资源实体签订合约；在信任更新机制中将推荐行为发生后总体信任值作为较真实的信任值，与中间实体推荐信任值比较，根据二者的误差生成反馈，调整对此实体的信任度。

Here, for k the value of UTS is taken. The k' is the required fatigue stress that would result in a damage of 1 for the occurring stress spectrum.

这里的k值采用的是悉尼科技大学的指标，k含义为：在应力发生图谱中，造成疲劳损伤值为1所需要的疲劳应力值。

The article,based on the real measured data,combining years of testing experience and railroad engineering theory,analyses measured error of stagger value of contact wire qualitatively and quantitatively arised from running speed ,elicits a expressions of speed-expiation for stagger value in real-time measure,improves real-time measured precision of stagger value.
