重复试验

Above all, buffalo is degree of a kind of seed selection is planted relative to inferior cultivate, have stronger vitality, disease-resistant force and be able to bear or endure the ability of thick raise, from development degree taller Italy arrives the less-developed country with development inferior degree, on the history, buffalo is done not have or had fed the feed of animal source sex such as pink of flesh and blood, fish meal without raise almost, straight so far, the whole world returns the report of disease of mad without a buffalo happening ox or urticant disease, be like mad ox disease, urticant disease, avian flu, Aibola disease to wait for harm mankind health in more and more animal sex diseases today, we can say, buffalo still is a god-given Sukhavati; so far next, the gust of water milk and its nutrition character have other to suckle kind of dominant position that cannot compare, an orgnaization of England undertook grandma of water milk, grandma milk, goat and artificial synthesis are suckled savour an experiment, via repeating for many times, join the person that try to be able to accurate winkle buffalo is suckled and state they are right the partial; of its gust the 3rd, as the addition of global population and the growth that suckle kind of consumption group, allergic to milk number also rises ceaselessly, but have to suckling milk.

首先，水牛是一种选育程度相对较低的畜种，具有较强的生命力、抗病力和耐粗饲的能力，从开发程度较高的意大利到开发程度较低的欠发达国家，在历史上，水牛就没有或几乎没有饲喂过骨肉粉、鱼粉等动物源性饲料，直到目前为止，全世界还没有一例水牛发生疯牛病或痒病的报道，在越来越多的动物性疾病如疯牛病、痒病、禽流感、埃博拉病等危害人类健康的今天，我们可以说，水牛到目前为止仍是一块难得的净土；其次，水牛奶的风味及其营养特性具有其它奶类不可比拟的优势，英国的一个机构进行了一次水牛奶、奶牛奶、山羊奶和人工合成奶的品味试验，经多次重复，参试者都能准确的挑出水牛奶并表示他们对其风味的偏爱；第三，随着全球人口的增加和奶类消费群体的增长，对牛奶过敏的人数也不断增长，但对奶牛奶有。。。

The results of lattice beam internal force calculated method based on double parameter groundsill model are more approach the experiment measured values because of consideration of the pass of shearing force in soil, and its calculated workloads are similar with the method of winkler elastic foundation. Besides, the thesis also discusses the moment of torque affected results on node stress situation and the correction of stress value at the bottom of cross node of lattice beam. Due to the repeat calculation of node area during internal force calculation, the stress value of the bottom of beam is lower, this may lead the calculated value unsafe, but the corrected stress value will more approach to practical situation.

对格构梁的内力计算提出基于双参数地基模型的格构梁内力计算方法，其计算结果表明，双参数地基模型上的格构梁内力由于考虑土中剪力的传递更加接近于试验实测值，其计算工作量与winkler弹性地基梁法相当，此外，文中还探讨了扭矩作用对格构梁节点受力情况的影响结果以及格构梁交叉节点底部的应力值的修正，由于内力计算过程中节点处的面积被重复计算，使得梁底应力偏小，可能导致计算结果的偏于不安全，修正后的应力值更接近于实际情况。

In experiment 1, 16 crossbred beef cattle (Limousin×Luxi), 12 months old and weighing about 350kg, were randomly allotted to four treatments with four steers per group for VA supplementation containing 0, 50%, 100%, 200% of 2200 IU/kgDM respectively, the standard of the nutrient requirements of beef cattle.

试验一：选用16 头体重约350kg 的健康利木赞×鲁西黄牛杂交一代育肥肉牛，随机分为4 个处理，每个处理4 个重复，分别饲喂添加不同浓度VA 的日粮。
