Values of hydration number of amino acids have been calculated at different temperature and concentration of denaturant. It is found that they decrease with increasing temperature and concentration of denaturant. Denaturant and increasing temperature have cooperative dehydration effect on amino acids.

计算了不同温度和变性剂浓度下氨基酸在乙酸钠、丁酸钠、己酸钠、辛酸钠和盐酸胍水溶液中的理论水化数，发现它们随变性剂浓度的增加和温度的升高而减小，说明变性剂和升温对氨基酸有协同脱水作用。

C. I. Reactive blue KN-R, Alizarin brilliant green G and Hostlam blue R could not be degraded by Zoogloea HP3. Furthermore, ABAS degradation was regressed under the exisitence of the above dyes. 1-Aminoanthraquinone-2sulfonic sodium, 1, 4-dihydroxylanthraquinone-2-sulfonic sodium, 1, 4, 5, 8tetrahydroxylanthraquinone, anthraquinone, aniline, phenol, catechol and ophthalic acid could be degraded by Zoogloea HP3. Aniline was the most degradable substrate among ABAS, aniline, phenol, catechol and o-phthalic acid. However, benzenesulfonic sodium and p-amino benzenesulfonic sodium were not degraded by it.

动胶菌HP3不能降解活性艳蓝KN-R、弱酸性绿GS及毛用活性蓝HW-R等蒽醌型染料，且染料的存在对菌体降解溴胺酸有不同程度的抑制作用；动胶菌HP3可以降解1-氨基蒽醌-2-磺酸钠、1，4-二羟基蒽醌-2-磺酸钠、1，4，5，8-四羟基蒽醌、蒽醌及苯酚、邻苯二酚、苯胺、邻苯二甲酸等苯系化合物，而不降解苯磺酸钠、对氨基苯磺酸钠；在溴胺酸、苯酚、邻苯二酚、苯胺、邻苯二甲酸中，苯胺是动胶菌HP3的天然底物。

However, the quality of the copper film deposited by this method is poor. In order to resolve this problem, we study the influence of some additives on two different kinds of electroless copper plating which using sodium hypophosphite as reducing agent and sodium citrate as chelating agent, sodium citrate and ethylene diamine tetraacetic acid disodium salt (EDTA·2Na). Electrochemical methods were used to test the anodic and cathodal polarization processes which can explain the mechanism of the influence of additives.

然而该体系所得的铜膜质量较差，为此我们研究了以次磷酸钠为还原剂，分别以柠檬酸钠为单一络合剂，柠檬酸钠和乙二胺四乙酸二钠为双络合剂体系中，研究了几种添加剂对化学镀铜的影响，并通过电化学方法研究了各种添加剂对化学镀铜沉积电位的影响。

Under the same concentration, tadalafil induce higher ratio of relation responses in the smooth muscles of CRF rabbit cavernosal strips, compared with papaverine and sodium nitroprussiate, with most significant difference occurring under the concentration indicators of 10-5 mol/L and 10-4 mol/L (P.01). Conclusions The effects of tadalafil on relaxation responses in CRF rabbit cavernosal strips highly depend on its concentration. The effect of tadalafil on relaxation responses in CRF rabbit cavernosal strips is better than that of papaverine and sodium nitroprussiate. Tadalafil may be an effective drug for treating CRF reduced erection dysfunction.

同一浓度下，他达拉非对慢性肾功能衰竭兔阴茎海绵体平滑肌舒张百分比与罂粟碱、硝普钠相比较，舒张百分比均大于罂粟碱和硝普钠，且在10~(-5)mol/L、10~(-4)mol/L浓度，他达拉非对慢性肾功能衰竭兔阴茎海绵体平滑肌舒张百分比，与罂粟碱、硝普钠相比较有显著性差异(P＜0.01)结论他达拉非对慢性肾功能衰竭兔阴茎海绵体平滑肌舒张反应的影响具有浓度依赖性，他达拉非对慢性肾功能衰竭兔阴茎海绵体平滑肌舒张反应的影响优于罂粟碱及硝普钠，他达拉非可能是治疗慢性肾功能衰竭性阴茎勃起功能障碍的理想药物。
