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。

The inhibiting effect of aluminous compounds including on alkali-silica reaction in gravel and zeolitization perlite mortars were investigated. The aluminous compounds content, the alkali reactivity of the aggregate and the alkali content will affect the inhibiting effect.

从甲基化对嘌呤碱基电荷的影响，到甲基化引起碱基配对的改变造成碱基配对的诱变等都作了较为详细的探讨；在对甲基化诱变的探讨中，我们进行了热力学和动力学方面的研究，同时对碱基之间的质子迁移的难易程度也作了探讨；并在充分考虑水分子存在的情况下研究了甲基化对碱基之间的氢键作用和堆积作用的影响。

For example, significant correlation in Zunyi prefecture was found between smoking total scores and total nitrogen, nitrogen to nicotine ratio and nicotine, and between offensive odor and total nitrogen and chloride.

在省级尺度，烟叶化学成分与烟叶品质的关系更为复杂，需用更多的化学成分（碳水化合物、含氮化合物及矿质养分）才能综合反映烟叶的品质，如吸食总分与总氮、糖碱比、氮碱比、磷、镁显著相关，杂气与总氮、糖碱比、氮碱比、磷、镁和还原糖显著相关。

At the prefecture scale, the relationship became complicated between chemical components and leaf quality, and more chemical components were needed to represent leaf quality. For example, significant correlation in Zunyi prefecture was found between smoking total scores with total nitrogen, nitrogen to nicotine ratio and nicotine, and between offensive odor with total nitrogen and chloride.

And we also get the fact that many vat dyestuffs can not be suitable for spun-dyed for viscose as dyed-reagents with the way of "reducing-oxidizing", such as C.I. Vat Blue 6, C.I. Vat Red 29, C.I. Vat Black 29, C.I. Vat Orange 1, C.I. Vat Brown 3 and so on. But some vat dyestuffs have a stable color, such as C.I. Vat Green 3, C.I. Vat Black 8 and so on.

通过实验可知，还原蓝BC、还原大红R、还原灰BG、还原金黄RK、还原棕R等还原染料，在高浓度碱剂、带碱氧化等加工条件下会产生不可逆的色光变化，而且变化程度较大，使得这些染料均不能以&还原－氧化&方式应用于粘胶的纺液着色加工，而还原橄榄绿B、还原灰M等染料受高浓度碱剂、带碱氧化等因素的影响较小，色光较为稳定。
