实验室实验

Cows in perinatal period were used in the experiment. Through clinical symptom and laboratory examination, they were divided into six groups that were healthy multiparity cows, healthy primiparity cows,cows with fatty liver disease, cows with ketosis and cows with retention of fetal membrance, mastitis in cows.

本实验以进入围产期的57头奶牛为研究对象，通过实验室检查结合临床症状找出其中健康的经产牛、健康的头胎牛及患酮病、脂肪肝、胎衣不下、乳房炎的自然病例。

The purpose of the experiment is to use a simple model to simulate the force caused by ice upon the oil platform on the sea.

通过在实验室模拟实验，可以测量钻井平台在海冰作用下受到的力，产生的速度和位移，为钻井平台的设计、防护提供数据。

The other was aimed at developing novel solvent system instead of oleum. A kind of solvent system mixed by phosphotungstic acid and acetic acid was put forward.

在实验室中进行了催化剂的考察工作以及工艺条件的考察工作，对实验结果进行了分析和探讨，讨论了各催化剂的催化循环机理，并建立了相应的动力学模型。

Using 75 varied low frequency noise samples with adjusted-loudness as sound stimuli, we investigate sound quality for low frequency noise with paired comparison method.

The method of using formaldehyde buffer solution a b sorption-hydrochloric pararosaniline spectrophotometry to determine sulfur diox ide in air has higher sensitivity and good selectivity,and prevents from adoptin g mercurial absorbent.But the conditions in lab are not well controlled,the v alue of reagent blank and standard curvilinear slope can't accord with the one s tipulated in"Methods for Air and Waste Gas Monitoring and Analysis".Some opra tional techniques for SO2 determination in lab are introduced for reference.

文摘：以甲醛缓冲溶液吸收-盐酸副玫瑰苯胺分光光度法测定空气中的二氧化硫，方法灵敏度高，选择性好，避免了使用含汞的吸收液，但如果实验条件控制不好，试剂空白值及标准曲线的斜率就会不符合《空气和废气监测分析方法》中规定的值，本文着重从操作技巧方面对二气化硫测定的实验室质量控制进行分析，仅供参考。

The split between the two groups can hardly be papered over.
