阴离子

It is unavoidable for body to exposure of organic anions including endogenous agents such as hormones, neurotransmitters and cellular metabolites, and xenobiotic agents such as medication, herbicides, pesticides, and plant and animal toxins.

机体接触各种潜在毒性有机阴离子，包括内源性物质如激素、神经递质和细胞代谢产物；外源性化学物质如多种药物、农药和动植物毒素等。

The MSDs assemble to form a low conductance (6-10pS) anion-selective pore with deep intracellular and shallow extracellular vestibules separated by a selectivity filter.

MSDs构成一个低电导(6~12pS)的阴离子选择性孔道，其形状如同不对称的沙漏，胞外小胞内大，狭窄部分为离子筛。

Complexes 7-12, 16, 22 and 23 are dimeric molybdatesor dimeric tungstates, the central metal with citrate or malate in a molar ratio of 1:1. Theanions of these complexes have two metal atoms and two ligands. Each ligand acts as atridentate fashion via theirα-alkoxy,α-carboxy andβ-carboxy groups coordinated to eachmetal atom. Complex 13 is a monomeric molybdate. The citrate ligand coordinates tomolybdenum with itsα-alkoxy,α-carboxy andβ-carboxy groups in a tridentate mode.

其配阴离子中都含有2个金属原子和2个配体，且配体均以α-烷氧基、α-羧基和β-羧基氧与中心金属三齿配位。13是单核柠檬酸钼配合物，柠檬酸也以α-烷氧基、α-羧基和β-羧基氧与钼三齿配位。17和21分别为苹果酸钼、柠檬酸钨单核配合物，其中苹果酸、柠檬酸配体均以α-烷氧基氧和α-羧基氧与金属双齿配位。

The scavenging effect of polyphenols extracted from grape seeds such as monomers, dimers and trimers on superoxide and hydroxyl radicals is studied with the ESR spin trapping method. The results are comparable with those obtained from chemiluminescence method. It has been proved that polyphenols extracted from grape seeds have a strong scavenging effect on Oxygen free radicals. Probably this is the reason why drinking some grape wine every day is good for one's health.

用ESR自旋捕集技术研究了从葡萄籽分离的单体、二聚体和三聚体等多酚类物质对羟基自由基和超氧阴离子的精除作用，并与化学发光法的测定结果进行了比较，得到了较一致的结果，证明葡萄籽中多酚类物质对氧自由基的确有较好的清除作用，这很可能是喝少量葡萄酒有利于身体健康的原因。

A highly effective and efficient phosphorus-free, nitrogen-free and biodegradable sequestering agents and detergency builders Polyepoxysuccinic acid was synthesized through negative ion synthesis.

以顺丁烯二酸酐为原料，通过环氧化反应和阴离子聚合的方法，合成了一种无磷、非氮、生物降解性好的环保型阻垢剂聚环氧琥珀酸。

The remaining anion s include negatively charged proteins, phosphates, and sulphates.

剩余的阴离子包括带负电荷的蛋白、磷酸和硫酸。

The remaining anions include negatively charged proteins, phosphates, and sulphates.

剩余的阴离子包括带负电荷的蛋白、磷酸和硫酸。

In addition, UE/HPLC/ICP-MS equipped with anion exchange column to speciate Cr and Cr in the μg/L level. H2 and He were used as collision gas in the ICP-MS detection to reduce the interference of multiatomic ions for Cr-52 ion monitoring.

又为继续提高灵敏度，本研究也使用超音波震荡/阴离子交换管柱的高效能液相层析/感应耦合电浆质谱法将三价铬及六价铬分离，并且将侦测范围降低至μg/L。

The naphthenic acids in 200~430℃ distillate of Liaohe crude oil were separated by column chromatogram and anion exchange resin.

采用柱色谱和阴离子交换树脂法分离出辽河200~430℃馏分油中的环烷酸。

There are different types of model available.17,18 For ionic dye-fibre systems, such as cellulosics, polyamide or acrylic dyeing, they are all based on the concept that the amount of dye sorbed by the fibre depends on electrostatic interactions and the dye's affinity for the substrate.

现有很多种类的模型，用阴离子染料染色的纤维，例如纤维素纤维，尼龙或丙烯酸纤维，这些纤维染色时，染料的上染率取决于染料和纤维的静电作用，以及染料对纤维的亲和力。

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.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
