The results indicate that the weak election-withdrawing group 4-hydroxymethyl in 4-position of pyridine in 4-HMDPA could weaken the fluorescence intensity of the lanthanide complexes. The contradistinctive experimental results show that the fluorescence intensities of these complexes are related to pH value of the aqueous solution and the dipole moment of solvent molecule: in the neutral aqueous solution,the fluorescence intensities of these complexes were strongest,while the less the dipole moment was,the stronger the fluorescence intensity was.

结果表明，在吡啶4位引入弱吸电子基团4-羟甲基会减弱稀土配合物的荧光强度；在水溶液中稀土配合物与溶液的pH值有着密切的关联，中性水溶液中荧光强度较大；分子偶极矩较小的溶剂中稀土配合物荧光强度较强。

在上述用量范围内，未见试验鱼有毒性反应；鱼体营养成份和几项生理指标与对照鱼相当，鱼肉中游离棉酚的含量为0.0009～0.0017％，此值远低于0.02％的食品卫生标准。

Limit cottonseed meal with high gossypol content to 5% of the layer diet (recent work indicates that up to 10% of some solvent-extracted cottonseed meal products can be safely used as they have low levels of gossypol due to newer varieties and improved processing).

要限制高棉酚的棉籽粕在产蛋鸡日粮中的用量不超过5%（最近有研究表明，一些用浸提工艺处理的棉籽粕可以用到10%，因为经过一些新品种以及加工工艺的改善，可以降低棉酚的含量）。

Thirdly, extraction method of coumarin from melilotus in the method of solvent was studied.

再次，重点研究了系统溶剂法提取草木樨中的香豆素。

我公司主要经营天然胶、合成橡胶、化工辅料，并生产各种型号的石油树脂、古马隆、溶剂油等多项品种。

As an important industrial solvent,it is capable to dissolve cellulose ether, cellulose ester, nitrocellulose ,alkaline base dyestuff, PVC, polyvinyl acetate, polymethylmethacrylate, polystyrene, coumarone resin, 100% phenol resin, modified phenol resin and various natural resins.

能溶解纤维素醚、纤维素酯、硝化纤维素、碱性染料、聚氯乙烯、聚醋酸乙烯酯、聚甲基丙烯酸甲酯、聚苯乙烯、香豆酮树脂、100%酚树脂、改性酚树脂以及多种天然树脂，是一种重要的工业溶剂。

In this paper, the recent development of high-speed countercurrent chromatography applied in the fields, including the selection of solvent system, the separation of active ingredient and the method of separation, are reviewed.

文中对高速逆流色谱用於分离中药有效成分的溶剂系统选择、采用该方法分离的中药有效成分以及分离手段等方面的研究状况进行了综述，并展望了该领域的研究前景。

Its bonding characterization and stability are discussed. The results show that these complexes are covalence complexes and that both the in-plane σ-bond and the in-plane π-bond in these complexes play an important role. The ESR spectra of VO -Ser system, VO -Ser-Phen system and VO -Ser-Bipy system in binary solvent glycol/water (V/V=1: 1) solution at various acidities (pH=1～14) have been observed at low temperature. It is found that in different pH ranges different structural complexes are formed.

测定了五种氨基酸席夫碱铜配合物的室温多晶粉末ESR谱、在不同溶剂中的室温及低温溶液ESR谱，确定配合物的配位环境；对室温溶液谱中观察到的二级效应和驰豫效应给予了理论解释、计算了驰豫参数；根据低温ESR波谱，计算了配合物的成键特性及稳定性，发现此类配合物为共价型配合物，平面内σ配键和平面内π配键均起重要作用。
