分离性

The surface tension of silicone oil can be reduced to 12 to 14 ergs/cm2 by the absorption of lipoprotein.

我在沙发上说的硅油有钝性分离作用，不仅仅是表面张力，或者浮力的作用。

My view is that there is no such dichotomy in biology between macroorganisms and microorganisms or prokaryotes and eukaryotes.

我不认为生物学应存在宏生物与微生物或者原核生物与真核生物的鸿沟性分离。

After the sequence and open reading frame were confirmed by DNA sequencing, the GADes gene was expressed in E.coli. SDS-PAGE analysis suggested that the bacteria BL21 produce a kind of fusion protein of 92KD and the expressed GADes fusion protein shows expected immunoreactivity by Western Blot.

SDS-PAGE电泳和Western Blot分别鉴定融合蛋白大小和免疫活性后，对表达条件进行优化，对包涵体进行分离、溶解和复性处理，以提高可溶性融合蛋白的产量，使融合蛋白达总蛋白的50％，相当于1.495g/每升培养物。

Was isolated from the diseased leaf of Cynodon hybrid in Red Lotus Lake golf courses in E-zhou. Pathogenicity was tested by inoculating the leaf with mycelium plug of Curvularia sp., the result indicated that Curvularia sp. isolate was the pathogen.

研究结果如下：从鄂州红莲湖高尔夫球场的狗牙根发病植株叶片上分离菌株Curvularia sp。，用菌丝块接种狗牙根叶片进行致病性测定，证实Curvularia sp。

The gas chromatography quantitative analysis conditions of gum rosin were studied by selection of chromatographic columns and chromatographic resolution conditions with the pure rosin sample of P.

用纯思茅松松香样品，通过选择色谱柱和色谱分离条件，研究确定了脂松香气相色谱定量分析的条件，定量分析了松香树脂酸的相对百分含量；定量分析数据通过统计学中的Grubb′s检验法进行误差检验，在确定的条件下脂松香气相色谱定量分析结果具有稳定性、准确性和复现性结果；对马尾松、湿地松松香定量分析也取得同样结果。

Their activities, heat-proof, acid-proof and alkaline-proof of the two enzymes were inhibited with increasing TBT concentrations.The effect of TBT on the phagocytic activity of oyster haemocytes was studied in vitro and in vivo.

从未受污染的牡蛎个体中分离的碱性磷酸酶和超氧化物歧化酶的活性、耐热性、耐酸碱性均随TBT浓度的增大而降低。

MethodsPolyprenols separated and purified from ginkgobiloba L were administered alone and in combination with 5 Fu,CTX and PDD,and in contrast with 5 Fu,CTX and PDD alone,the experiments were carried out on mouse transplanted Heps and EC.

方法从银杏叶中分离纯化聚戊烯醇，分别与氟脲嘧啶(5 Fu)、环磷酰胺和顺铂联合应用，对移植性Heps和EC荷瘤小鼠进行抑瘤实验，并与 5 Fu、CTX和PDD单独用药比较。

The samples made by steam distillation do not contain any high-boiling and non-volatile materials and no contaminants are introduced to GC; but highly polar or hydrophilic compounds are not easy to be extracted.

蒸汽蒸馏方法制备的样品通常不含高沸点或非挥发性组分，不会对GC造成污染；但一些极性大或亲水的组分不易分离出来。

The phenomenon is caused by the control of formation water on the hydrogen sulphide formation and by the incomplete separation of water and gas due to strong heterogeneity of reservoirs.

结果表明，地层水对硫化氢生成的控制作用和储层强非均质性导致的气水分离不彻底是&硫水耦合&的关键。

In the contaminated lard sample, 6 organic compounds have been thus identified to be the raw materials or byproducts in the production of organic tin compounds. Based on the identified contaminants, it can be postulated that the chemical structure of the organic tin compound is dibutyltin-bis-(2-isooctyl thioacetate). The method is simple and precise, and has not been reported in the local literature.Keywords Organic tin compound, Lard, SPME－GC－MS

经过摸索研究，采用固相微萃取方法富集挥发性杂质，直接注入色谱中，经色谱分离，质谱测定，确定了杂质的结构，由杂质成分推断生产有机锡所用的原料，然后判断合成路线，最后确定有机锡的结构，从有毒猪油中鉴定出2－巯基醋酸异辛酯、双（2－醋酸异辛酯）二硫、双醋酸异辛酯硫醚等6种与有机锡有关的杂质，并与相应的有机锡工业品对照，发现工业品中也含有这些杂质，与其合成过程的原料及副产物相符，从而确定有机锡化合物为二硫代醋酸异辛酯二丁基锡。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
