和硫

Gas chromatography equipped with a nitrogen-phosphorus detector was used in the field residue decline study and final residues of malathion in citrus and soil.

采用气相色谱测定了马拉硫磷在柑桔及土壤中的消解动态和最终残留。

Rotational regression design was employed to modeling the degradation of malathion and butachlor in water.

以下是马拉硫磷和丁草胺在水体中降解的数学模型，式中，y-水体中农药残留浓度μg·L~(-1；x_1-温度；x_2-时间；x_3-初始浓度μg·L~

Pesticide contamination is considered one of the most contaminated sources of environmental water. Atrazine, Chlorpyrifos, Malathion and Butachlor were applied intensively and more frequently detected in environmental water in China.

农药残留物是水环境的重要污染源之一，莠去津、毒死蜱、马拉硫磷和丁草胺是我国农业上使用量较大且在环境水体中检出率较高的四种农药。

Most of 〓 uptake by ryegrass came from MCP-〓,and little from 〓 and 〓.

植物吸收的硫绝大部分来源于〓，极少来自〓和〓。

Monodispersed SAM-protected Au nanoparticles are biosynthesized extracellularly by an efficient, simple and environmentally friendly procedure using Bacillus megatherium D01 and Bacillus licheniformis R08 as the reducing agent and using dodecanethiol and mercaptoacetic acid sodium salt as the capping ligand at 26℃.

利用巨大芽孢杆菌(Bacillus megaterium，菌号D01)和地衣芽孢杆菌(Bacilluslicheniformis，菌号R08)作为还原剂，分别以十二烷基硫醇和巯基乙酸钠作为保护剂，生物合成了单分散的Au MPCs。

This odor often gradually diminishes as treatment continues and is thought to be related to metabolism associated with the prosthetic mercaptan and possibly excretion of toxic metals.

继续治疗时，这些味道会减轻，据说是跟新陈代谢和非朊基的硫醇和有毒金属的排泄有关。

Because of improved separation of the product gas mixture into its components, less hydrogen sulfide and methyl mercaptan are lost in discharging the inert gases than in the known process.

由于将产品气体分离成其组分的改进方法，与已知技术方法比较，在惰性气体的排放中损失的硫化氢和甲硫醇较少。

It provides a route tothe compounds which contains three functional groups, two carbon-nitrogentriple bonds and one carbon-carbon double bond. In water, metallic indiumpromotes carbon-sulfur bond coupling reaction of aromatic sulfonyl chloride withsuitable organic halides to afford sulfones. In the last chapter, metallic tin mediated allylation of aldimines with allylbromide was revealed.

第三章，我们研究了在水相介质中金属铟促进的烯丙基溴对1，1-二氰基-2-芳基乙烯的Michael加成反应，生成一个含碳碳双键和二个碳氮叁键的三官能团化合物，另外，金属铟在水介质中还可以促进芳基磺酰氯与卤代烃发生碳硫键的偶联，生成砜。

The determination method of endosulfan and deltamethrin pesticide residues in fishery products was established by gas chromatography.

建立了气相色谱法快速检测水产品中硫丹和溴氰菊酯残留量的分析方法。

Then the characteristic and the mechanism of the fluorescence spectra of methyl parathion standard solution are explained.

由此对甲基对硫磷标准溶液荧光光谱的产生机理和特性作出了解释。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。

Designed by French fashion house Herm è s, this elegant uniform was manufactured in our home, Hong Kong, and was the first without a hat.

由著名品牌 Herm è s 设计，这件高贵的制服是香港本土制造，是我们第一套不配帽子的制服。
