Select aloes as the raw material, the experiment studied the proportion after adding aloes stock, water , milk , white granulated sugar, lactic acid as well as the parameter of stabilizer and heat treatment. According to the experiment, the best formula and technical parameters were determined. The quality of the product was also evaluated.

摘 要：以芦荟为原料，试验对加入的水、牛奶、白砂糖、乳酸的比例以及稳定剂，热处理的参数进行了研究，确定了芦荟牛奶饮料制作的最佳配方及工艺参数，并对产品的特性进行了评价。

We designed this double-blind comparison trial to assessthe efficacy of dimenhydrinate LA versus droperidol alone andthe combination for prophylaxis of nausea, vomiting, and retchingin outpatient gynecologic laparoscopy. One-hundred-forty-onewomen were randomized into 3 groups: 1 droperidol (placebocapsule preoperatively and IV droperidol 0.625 mg before induction),2 dimenhydrinate LA preoperatively and IV placebo before induction,or 3 combination.

我们设计了这个双盲比较试验来评价门诊妇产科腹腔镜检查中晕海宁 LA 对比氟哌利多单用及二者合用预防恶心、呕吐和干呕的功效。141例女性随机分成3组：1 氟哌利多（术前安慰剂胶囊，诱导前氟哌利多0.625 mg IV ）；2 术前晕海宁 LA ，诱导前安慰剂 IV ；3 合用。

Apart from those aspects, the cultivation of the students'cooperative ability and theirsuitability for society is also taken into consideration.

从心理学角度来看，学生进行愉快和谐、富有成效的合作学习，自然会产生快乐有趣的情绪气氛，这种学习氛围一旦形成并保持下去，必会给学生带来高涨的学习热情，推动他们进行孜孜不倦、锲而不舍的努力，有利于学生的全面发展。20世纪80年代以来，我国中小学教育界对合作学习给予了极大的关注，一些学者和专家对合作学习进行了大量的研究和试验，走过了从移植到改良，从改良到创新的探索历程，取得了富有成效的成果，但现在大家对合作学习的理解仍存在不少分歧，并且相当多的研究局限于理论层面，具体的操作性方法、教学模式及评价方面的研究较少，尤其是在与物理教学的整合上更是欠缺，给物理教学开展合作学习带来不便。

Key words:Normal butyl alcohol extraction; Ames; Fluctuation test; Sensitivity

因此这些方法是较好的化学物质诱变活性评价的试验方法。

To analyze the reliability and comparability of different hematology analyzers and to standardize the operation of a contrast test. Methods The carryover rate, precision, total precision and percentage of differences of hematological analyzers were evaluated and differences of items in whole blood were compared by detecting 20 anticoagulant fresh blood samples based on the documents of ICSH and NCCLS. Every 3 blood samples of highvalue, middlevalue and lowvalue were detected by hematological analyzers everyday for 7 days.

方法参照国际血液学标准化委员会及美国临床实验室标准化委员会文件，在仪器正常运行的情况下，评价各比对仪器的携带污染率、精密度和总精密度、差异百分率；分析比较20份抗凝新鲜全血中各项指标在不同血细胞分析仪之间的差异；每日取高、中、低3份新鲜血，在各仪器上平行检测，连续比对7日，观察各项指标与参考样机之间的相关性；分析比较仪器分类与手工分类的相关性；通过直线回归方程计算相对偏差，估计每台仪器各检测指标的试验误差。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
