Management of the turbidness in yellow wine are as follows: firstly, we should produce quality wine and prolong the fermentation period so that the microbes could be dissolved completely; the optimal storage period is 2～3 year for natural sedimentation; remove the turbidness; the best wine－boiling temperature is 80～85℃; the production facilities should be stainless to avoid the turbidness caused by metal ions; furthermore, we could remove the turbidness by the methods of refrigeration and addition of clarificant etc.

解决黄酒浑浊问题首先要酿好酒，延长发酵期，分解微生物完全彻底；存贮期以2～3年为好，起自然沉淀作用；割除酒脚；煮酒温度掌握在80～85℃；黄酒生产设备应采用不锈钢，避免金属离子产生沉淀；此外，可通过冷冻处理、添加澄清剂等方法除去浑浊沉淀物。

The optimal measuring conditions were investigated. The results indicated that the catalytic reaction to Pt and bromocresol purple was the first-order reaction. The apparent activation energy was 217.4kJ/mol and the maximum absorption wavelength of fading reaction was at 434 nm. The linear range of Pt was 0.16-4.0μg/L and the detection limit was 2.5×10^(-11)g/mL. Most of common ions had no interference with the determination, while ten multiples of Ru, Rh and Os had interference with the determination of Pt. Therefore.

选择了最佳测定条件，实验结果表明，催化反应对铂和溴甲酚紫为一级反应，反应的表观活化能为217.4kJ/mol，褪色反应的最大吸收波长为434nm，方法测定R哪的线性范围为0.16~4.0μg／L，检出限为2.5×10^(-11)g/mL，大多数常见离子不干扰测定，10倍以上的Ru，Rh和Os对测定有干扰，可在测定前分离除去。

The scFv formed inclusion body in E. Coli. 8 mol/L urea was used to solubilize the inclusion body, and the scFv was then purified in two steps , including Ni 2+ chelating affinity chromatography and gel filtration.

大肠杆菌表达的单链抗体包涵体，用8 mol/L尿素裂解，经过Ni离子螯合亲和层析和凝胶过滤两步纯化后，纯度达到97%以上，再通过透析复性除去尿素。

The native oxides on CdSe surface could be reduced to elemental Selenium by a HF etching process. Bombardment using 100eV Ar〓 ions with a dosage of about 1×10〓 ions/cm〓 could remove all the elemental Selenium, which results in a normal stoichiometrical surface CdSe.

实验观测到HF刻蚀可以将CdSe半导体表面的Se氧化物还原为元素Se.100eV的Ar〓离子轰击可以除去HF刻蚀后在表面还原生成的元素Se，从而清洁样品表面，保证了表面CdSe的化学计量比。

The large amount of tin and antimony in the sample can be volatilized after dissolved in the saturated solution with hydrochloric acid and bromine .

试样中大量锡、锑以盐酸溴饱和溶液溶解挥发除去，在凝聚剂硝酸锶存在下，铅离子与k2Cr2O7标准溶液在PH3～4以PbCrO4快速形成沉淀析出[1]。

The water produced in the reactions did not need to be removed during the reaction because BF4 was miscible with water while the acetals or ketals were immiscible with BF4. Hence the product could be separated conveniently bydecanting.

反应中生成的水不需要被除去，因为反应中生成的水会被BF_4吸收，而大部分缩醛、缩酮产物则不溶于BF_4，可通过简单的重力沉降分离，离子液体仅需简单减压除水后即可循环使用。
