Replacing complete concentrated feed with mixed concentrated feeds of dwarf elephant grass, brachiaria hybrid Ⅰ and brachiaria hybri Ⅱ, there was no significant effect on the growth and acetone body quality of young goose. The three acids glyceride and high density lipoprotein of serum from 80 day-old geese had no significant difference, but the total cholesterin and low density lipoprotein of geese fed with dwarf elephant grass, brachiaria hybrid Ⅰ and brachiaria hybri Ⅱ were all lower than that fed with concentrated feed to some extent.

用矮象草、臂型草杂种Ⅰ、臂型草杂种Ⅱ混合精料代替全精料养鹅并不会显著影响仔鹅的发育和酮体品质。80日龄鹅的血清TG和HDL差异不显著，但矮象草、臂型草杂种Ⅱ和臂型草杂种Ⅰ饲养的鹅，TC和LDL都一定程度上低于精料组的鹅。

The results showed that acidifier supplementation in the diet at different levels improved feed intake and daily weight gain in a quadratic manner. The supplementation of organic acid improved the availability of DM, protein, organic compound and energy in the broilers at the age of 0-21 days. Comparing with the control test, the supplementation of 0.05%, 0.3% and 0.4% organic acid improved the availability of protein p

结果表明：①饲粮添加不同剂量乐达酸化剂，使肉鸡采食量和日增重呈二次曲线变化；②饲粮添加有机酸能不同程度改善肉鸡0-21日龄饲粮干物质、蛋白质、有机物和能量的利用率，与对照组相比，0.05%、0.3%和0.4%乐达酸化剂组饲粮蛋白质利用率极显著提高p

A batract : A trial was conducted to investigate the effects of adding Rovabio AP10% alone or in combination with phytase and acidifier at different ME levels (2.55, 2.60 and 2.65 Mcal/kg) and available P levels (0.28 and 0.36%) on the layers performance and egg quality. 2160 Hi-Line Brown of 22 weeks old with the same body weight and uniformity were used in this trial. The birds were randomly divided into 9 treatments, 8 replicates/treatment and 30 birds/replicate.

为探讨罗酶宝AP10％及罗酶宝增强型在蛋鸡日粮中的高效使用技术，试验选用22周龄体重、均匀度一致的健康海兰褐蛋鸡2160只，随机分为9个日粮处理组，每个处理8个重复，每个重复30只鸡，检测不同代谢能（2.55，2.60，2.65Mcal/kg），不同日粮非植酸磷水平（0.28，0.36%）条件下单独添加罗酶宝AP10％或罗酶宝增强型，以及与酸化剂同时添加后蛋鸡生产性能和蛋品质的影响。

The basic Arrhenius equation in the physical-chemical reaction is introduced to control the hydration process of the cement.

阐述了水泥水化反应遵循物理化学反应中Arrhenius方程的规律，用&等效龄期&的概念考查了温度对于混凝土弹性模量的影响，进行了某碾压混凝土拱坝施工期温度场的计算，并利用该温度场及&等效龄期&进行了应力场的计算，该应力计算中包含了温度及自重徐变应力。

The hydration heat model of concrete is established on the basis of Arrhenius law that is adopted to analyze the influence of temperature on heat evolution rate of early-age concrete.

混凝土结构的早龄期非荷载开裂是影响混凝土结构耐久性的主要原因之一[1]，所以在混凝土结构设计阶段对混凝土的早龄期抗开裂能力进行分析是十分重要的。

The results show that during the development of the oriental tobacco leaves, the activity of acid invertase was decreased; the changes of GS reached its peak in the 20dans in Samsun, but in the 30dans in Basma and Canik ;the activity of PAL was decreased in the 30dans; The content of total nitrogen was decreased with the mature leaves, but nicotine、total carbon and soluble total sugar were increased. Different varieties, carbon and nitrogen metabolism key enzyme activity and the content of metabolites were different.

结果表明，在香料烟叶片发育过程中，酸性转化酶的活性均呈下降趋势；谷氨酰胺合成酶的活性Samsun品种在20d叶龄时最高，而Basma和Canik在30d叶龄时最高；苯丙氨酸解氨酶的活性均表现为30d时最低；随着叶片成熟总氮含量降低，烟碱含量升高，总碳、可溶性总糖随着叶片成熟其含量呈升高趋势；品种不同，碳氮代谢关键酶的活性及代谢产物的含量变化均有很大差异。

Result In the experimental 11 groups, heart rates of young Hailan chickens were close to that of others, but their values were higher than that of chickens in old days. Breathing frequency test showed 140, 280 and 420 days old chicken were significantly different with others. Contraction and diastolic pressures of 6 groups were gradually increased with growth of days, that of 280 and 420 days chicken were significant different.

结果］在11组中，小年龄段海兰鸡心率与其他鸡心率接近，但高于大年龄段的心率值；呼吸频率测定结果140、280和420日龄组与其他组差异极显著；6组海兰鸡收缩压与舒张压都是随着年龄的增长而升高，28与420日龄组差异极显著。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
