过酸

There are other metal arsenates, such as those of Fe,Zn,Cu, and Pb, which are less soluble and more stable in the neutral pH region than calcium arsenates or ferric arsenate, but these have not been seriously considered as disposal forms.

还有其他金属砷酸盐，例如那些 Fe、 Zn、 Cu和 Pb，比起砷酸钙或者砷酸铁来，这些物质在中性的 pH 值范围内很少是可溶并且更稳定的，但是这些物质没被以处理的形式认真慎重地考虑过。

The method is characterized in that: mixture of macromolecular dihydric alcohol and a dihydroxybutyl-terminated polydimethylsiloxane is dehydrated, added with diisocyanate for reaction, then added with a bis propionic acid, a dihydric alcohol chain extender and a catalyst - dibutyl tin laurate, and is diluted by acrylic ester; temperature reduction and emulsion are performed on the mixture after reaction; chain extension reaction is performed in water by a multi-amine chain extender, and siloxane modified polyurethane dispersoid which contains acrylic ester monomer is prepared; and an initiator - potassium persulphate is added into the siloxane modified polyurethane dispersoid for emulsion polymerization.

特征是先将大分子二元醇与二端羟丁基聚二甲基硅氧烷的混合液脱水后加入二异氰酸酯，反应后加入二羟甲基丙酸、二元醇扩链剂和催化剂二月桂酸二丁基锡，并用丙烯酸酯进行稀释，反应后降温乳化，用多元胺扩链剂在水中进行扩链反应，得到含有丙烯酸酯单体的硅氧烷改性聚氨酯分散体，然后再通过加入引发剂过硫酸钾进行乳液聚合。

On the basis of the analytical results of infrared spectrometry,paper chromatography,tyrosine color development reaction and the assay of anti-acid buffer capability,we confirm that chlorine dioxide in stabilized solution with sodium percarbonate as stabilizer exists in the form of chlorition (ClO2-) and exists in NaHCO3-Na2CO3 buffer system. When the stabilizer is sodium perborate,chlorine dioxide may be retained in the solution comprised of H3BO3-Na2B4O7 as a labile complex.

通过对几种样品的红外光谱分析、纸色谱分析、酪氨酸显色反应及抗酸缓冲能力的测定，证实在以过碳酸钠为稳定剂的稳定液中，ClO2以亚氯酸根离子(ClO2-)形式存在，并处在一个由NaHCO3-Na2CO3组成的缓冲体系中；在以过硼酸钠为稳定剂的稳定液中，ClO2可能是以活性配位化合物的形式存在，并处在由H3BO3-Na2B4O7组成的缓冲体系中。

From this study, we can conclude that:1,there is no significantly difference in pH, [NH3-N], Acetate concentration, propionate concentration, intake, nutrient degradation, blood calcium, TCH and TG.;40g/d stearin in sheep can prominently increase the butyric acid concentration and

通过本研究得出：1，脂肪酸钙、植物脂肪粉以及硬脂肪对瘤胃PH、氨浓度、乙丙酸产量、干物质采食量、营养物质瘤胃降解率、血钙、TCH、TG等方面影响并不显著，但硬脂肪对丁酸以及乙丙酸摩尔比有显著影响(P.05)，植物脂肪粉对血镁浓度也有显著影响(P.05)2，过瘤胃脂肪对营养物质全消化道消化率影响较大，其中脂肪酸钙组与植物脂肪粉显著降低了蛋白消化率，植物脂肪粉能显著降低ADF和NDF消化率(P.05)，但处理组之间差异不显著。

According to classical nucleation theory, it was possible to distinguish the homogeneous and heterogeneous nucleation from the influence of temperature and supersaturation on induction period.

本文根据经典均匀成核理论，分别研究了硝酸酸沉和盐酸酸沉制备的四钼酸铵过饱和溶液的成核过程，并讨论了过饱和比和温度对成核速率及成核机制的影响。

The activity of superoxide dismutase in the myocardial cells was determined by the diphenol method, plasma malondialdehyde content was measured by TBA assay, the culture medium LDH content was measured by the acetonic acid method, the intracellular calcium concentration was measured by fluorescence spectropho- tometer- The results was shown that aspartate-K.

结果显示，门冬氨酸钾镁能减少阿霉素中毒心肌细胞乳酸脱氢酶的释放量，降低细胞内丙二醛含量及游离钙浓度，同时可升高细胞内超氧化物歧化酶活力；结果表明，门冬氨酸钾镁可能通过抗脂质过氧化及逆转细胞内钙离子过负荷作用进而保护中毒心肌细胞。

Were analyzed under different nutritional levels. The results showed that in tuber development, under- or over-supply of nutrients reduced ZT content at initial stage and IAA, ABA and JA content at middle stage, but increased GA content in the whole process, which caused GA/ABA and GA/JA to be off balance in the key stage of tuberization.

结果表明，过低、过高的营养供给，降低了块茎发育前期细胞分裂素的含量，中期细胞生长素的含量以及促进块茎发育的脱落酸、茉莉酸含量，增加了各时期促进匍匐茎发生的赤霉素含量，导致在块茎形成和膨大的关键时期，GA/ABA和GA/JA比值失衡，抑制了块茎的正常发育。

Were analyzed under different nutritional levels. The results showed that in tuber development, under-or over-supply of nutrients reduced Zeatin content at initial stage and indole actic acid, abscisic acid and jasmonic acid content at middle stage, but increased gibberellins content in the whole process, which caused GA/ABA and GA/JA to be off balance in the key stage of tuberization.
