Then one new method for deleting gross error based on Grey System Theory is proposed in experiment data processing to improve the measuring accuracy.

为了提高测量系统测量的精度，在测量系统的实验数据处理中提出了一种基于灰色系统理论的粗大误差判别法。

Methods To dispart the Ground beetle into four segments which were shell, head, chest and abdomen, and adopt the method of frozen and melt to do the further test.

将土鳖虫分为壳、头、胸、腹4部分，采用反复冻融法提取成分并进行进一步实验。

Based on the colour reaction of copper with sulfocyanate and crystal violet, a new spectrphotometric method for determination of copper in the presence of β-cyclodextrin and arabic gum is proposed. The factors such as acidity, reagent dosage, influence of surfactant and coexisting ions on the reaction were discussed and the optimal conditions were investigated.

研究了在β-环糊精和阿拉伯树胶存在下，在硫酸介质中，硫氰酸盐－结晶紫与铜的显色反应，建立了光度法测定铜的新方法；讨论了酸度、显色剂用量、表面活性剂和共存离子的影响，确定了最佳实验条件。

We should really call it half a step rather than a whole one.

事实上我们应该叫它半步而不是一整步，因为到目前为止，我们的注意力只一直集中在法拉第的实验上。

Because the majority of the Vibrio parahaemolyticus are halophile and utilize arabi-nose as a carbon source to produce typical yellow colonies on the SAC medium,whereas most of closely related species can produce only greenish minute colonies,the growth of usual marine microflora can be inhibited.

在检测方法上，改进了一种选择性较强的培养基，经实验表明，SAC培养基较其他常用的几种培养基对付溶血性弧菌检出的阳性率和灵敏度均较高，与普通采用的TCBS法比较，x~2=4.28，ρ。05，有显著效果的意义。

The hemocyanin was firstly isolated and purified by ultracentrifugation and gel filteration chromatography on Sepharose 4B column.

本实验通过超高速冷冻离心和Sepharose 4B凝胶过滤柱层析法从湖北钉螺血淋巴中提取、纯化了血蓝蛋白。

Surface modified nano-sized mgnesium hydroxide was prepared by direct precipitation method with magnesium nitrate hexahydrate and sodium hydroxide as raw materials,and sodium fatty alcohol polyoxyethylene ether carboxylate as modifying agent.The optimum dosage of modifying agent was 0.2% of the mass of magnesium hydroxide,which was confirmed by sediment volume experiment.Modified and unmodified samples were characterized by fourier transform infrared spectroscopy,X-ray diffraction,transmission electron microscope,and tap density test.

以六水硝酸镁、氢氧化钠为原料，脂肪醇聚氧乙烯醚羧酸钠为改性剂，采用直接沉淀法一步合成改性纳米氢氧化镁，用沉降体积实验确定改性剂的最佳用量为氢氧化镁质量的0.2%，通过红外光谱、X射线衍射、透射电镜、表观密度对改性前后的样品进行表征。

The A238/A440 was less than 0.20, the product rate was 48.91%, colourity was 218.12. The pigment was sensitive to acid , oxidant and Fe2 Cu2. This paper has proved that the pigment maintain stable under protection of glucose, sucrose and lactose. Meanwhile, the pigment showed heat- stability, preserve-stability and high-colored capacity in beverage, frozen foods and milk products.

采用凝胶层析法对栀子黄色素进行精制，原液中的A_(238/)A_(440)降到0.20以下，得率为48.91％，色素色价达到237.64 精制色素的稳定性实验表明：精制后的色素用于面食后没有绿变现象发生；酸性条件下色素的稳定性很差；糖能提高色素的稳定性；氧化剂会使色素褪色；还原剂和防腐剂对色素的稳定性影响不大；Fe~(2+)、Cu~(2+)对色素的稳定性影响较大；色素在饮料、冷冻食品和乳制品中的着色效果良好。

The new system could avoid the influence of high-concentration CO_2 or low pressure , was simple and cost2effective to make and convenient to use.

Griess法测定实验观察到，小白鼠脑组织中一氧化氮的含量随着年龄的增长而不断增加。

To solve the problem of high-concentration nitrogen and phosphorus in secondary effluent, nature zeolite was modified and compounded to remove nitrogen and phosphorus by using adsorption process.

针对二级出水中氮、磷含量较高问题，对采用吸附法去除水中的氮、磷的天然吸附剂进行了改性和复合处理实验。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
