Studied on sensitivities of C. ellipsoidea to kanamycin , Chloromycetin , Hygromycin , Streptomycin and Geneticin (G418), the results showed that C. ellipsoidea is not sensitive to Km, Str and Cm, 600μg/ml km, 600μg/ml Str and 200μg/ml Cm can not inhabited the growth of C. ellipsoidea. However, it is fairly sensitive to Hm, 100μg/ml can completely stop the growth of C. ellipsoidea on solid media. We also found that C. ellipsoidea was highly sensitive to G418, 30μg/ml and 15μg/ml can inhabit the growth of C.

通过5种基因工程中常用抗生素对小球藻生长抑制的研究发现：小球藻对卡那霉素、链霉素、氯霉素不敏感。600μg/ml的卡那霉素、600μg/ml的链霉素和200μg/ml的氯霉素仍不能抑制小球藻的生长；小球藻对潮霉素较为敏感，100μg/ml的用量可抑制固体培养中小球藻的生长；而对G418表现出高度敏感性，30μg/ml的G418即可完全抑制固体培养中小球藻的生长，15μg/ml的G418即可完全抑制液体培养中小球藻的生长。

Streptomycin is an Aminoglycosides antibiotics.It is effective to treat cow mastitis, infectious coryza and endometritis, and is frequently added into feeds for the prevention or treatments of animal diseases.

链霉素是一种氨基糖甙类抗生素，在医学上由于其存在严重的耳及肾毒性，已被其它新药所取代。

Inhibition of chlorophyll synthesis may be caused by etiolation, mutant blocks, or streptomycin

叶绿素合成可以由黄化、突变性阻塞或链霉素而引起。

The result showed that the best germicide was 72% streptomycin and 88% oxytetracycline hydrochloride. The control effect of 72% streptomycin was 66.34% in the field.

结果表明，室内抑菌效果比较好的是72%农用链霉素和88%水合霉素，大田防治效果最好的是72%农用链霉素，防治效果为66.34%。

This HILIC-MS/MS method is sensitive and specific to monitor and analyze of streptomycin and dihydrostreptomycin residues in honey.

结论该HILIC-MS／MS法灵敏、专属，适用于监测和分析蜂蜜中链霉素和双氢链霉素的残留量。

Objective A specific and sensitive liquid chromatography-tandem mass spectrometry method was developed to determine streptomycin and dihydrostreptomycin residues in honey.

目的建立一种专属、灵敏的液相色谱-串联质谱法测定蜂蜜中链霉素和双氢链霉素的残留量。

It has streptomycin and dihydrostreptomycin crossing rate of 100 %, simple sample pre-treatment including water dilution of milk sample and extraction with buffering phosphoric acid solution and pH regulation of pork and kidney sample, fast detection, high detection sensitivity up to 11.2 microgram/L and other advantages, and may be used in detection of residual streptomycin and similar medicines in animal food products.

本发明的检测链霉素药物的酶联免疫试剂盒为多残留检测试剂盒，链霉素和双氢链霉素的交叉率为100％；对样品的前处理要求低，样品前处理过程简单，牛奶样品用水稀释后可直接测定，猪肉和肾脏经磷酸缓冲液抽提后调pH即可上样，并且能同时快速检测大批样品；测定方法简单，省时，牛奶样品在1小时之内可得出测定结果；最低检测限达11.2μg/L，具有高特异性、高灵敏度、高精确度、高准确度等特点，可在动物性食品链霉素药物残留检测中发挥重要作用。

Methods Streptomycin and dihydrostreptomycin were extracted from honey samples using a liquid extraction with a phosphate buffer followed by a solid-phase extraction based on weak cation-exchange columns. After sample preparation, the hydrophilic interaction chromatography was used to retain streptomycin and dihydrostreptomycin on the column for the separation of the analytes from endogenous compounds. The aminoglycosides were detected and quantified with electrospray ionization tandem mass spectrometry.

方法用磷酸盐缓冲溶液提取蜂蜜中的链霉素和双氢链霉素后，经弱阳离子交换柱进行固相萃取，样品制备后采用亲水作用色谱，使链霉素和双氢链霉素实现保留，从而与内源性物质达到分离，采用电喷雾离子化串联质谱法检测和定量。

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.
