Clean energy economy will lead to higher consumption per capita than harmful energy economy when CER value is high enough and the cumulative net capacity is zero. On the contrary, clean energy economy will lead to lower consumption per capita than harmful energy economy when CER value is not high enough, which means it is not able to counterweigh the cost of ethanol, or when ethanol production efficiency is low enough.

3当CER价值足够高而净资本累积为零时，洁净能源体系会较污染性能源经济体系造成较高之人均消费；反之若CER价值不够高，亦即不足以弥补燃料酒精生产成本时，或者燃料酒精生产效率足够低，则可能获得较低的长期人均消费水准。

When pumped with 800 nm laser irradiation, 2 {4 [2 (4 dimethylamino phenyl vinyl] phenyl} ethylamino ethanol and 2 {4 [2 (4 diethylamino phenyl vinyl] phenyl} ethylamino ethanol show strong two photon induced blue fluorescence at 436 and 440 nm respectively, while DMANHAS and 4 nitro benzoic acid 2 {4 [2 (4 diethylamino phenyl vinyl] phenyl} ethylamino ethyl ester exhibit no fluorescence.

在800 nm的飞秒脉冲激光激发下，反式-4-(N-羟乙基-N'-乙基氨基)-4'-二苯乙烯和反式-4-(N-羟乙基-N'-乙基氨基)-4'-二苯乙烯均发出较强的蓝紫色上转换荧光，荧光峰分别位于436和440 nm，而DMANHAS和反式-4-[N-(乙氧基羰基-4-硝基苯基)-N'-乙基氨基]-4'-二苯乙烯没有荧光。

The method comprises following steps: taking diphenol and 3- trifluoromethyl- 4- chloronitrobenzene as raw material, salt precipitating for diphenol and potash, refluxing with water- containing toluene, reacting with 3- trifluoromethyl- 4- chloronitrobenzene and getting dinitro monomer; taking dinitro monomer, ferro powder and HCl as raw material, ethanol and water as disslovant for refluxing and ethanol recrystallization, getting fluorine- containing aromatic diamido monomer.

合成方法是以二酚与3-三氟甲基-4-氯硝基苯作原料，先将二酚与碳酸钾成盐，甲苯带水回流反应，然后与3-三氟甲基-4-氯硝基苯反应制得二硝基单体；再以二硝基单体，铁粉，HCl为原料，乙醇和水做溶剂，回流反应、乙醇重结晶，得到含氟芳香二胺基单体。

The continuous ethanol production with complete distillage recycle was availiable for a certain period provided that the dilution rate was controlled below 0.35 h-1, while an ethanol concentration and productivity of 63 g/L and 22.1 g/ could be achieved by this continuous fermentation system.

研究了用酒精滤液代替原来的工艺用水进行细菌酒精连续发酵试验的可行性；建立了单级无回流连续发酵系统，在稀释率为0.35 h-1时，酒精产量为 64.0 g/L，发酵强度达到22.4 g/；考察了回流比分别为0.5，1.0，稀释率为0.3，0.35，0.4 h-1时，滤液回流对连续发酵系统的影响。

Finally, the effect of the complete recycling use of distilled effluent on ethanol fermentation was examined in order to save the cost for the treatment of waste distillage and promote cleansing production. Based on the data of 13 circulations, although the average fermentation time needed to be extended to 30~40 hours, over 12.5% ethanol was achieved, at the same time, residual reducing sugar and total sugar were maintained below 0.70% and 0.90%, which indicates that the negative effect of the completely recycling use of waste distillage was limited, and the waste distillage can be completely recycled within the fermentation system.

在此基础上，从减轻废糟液处理负荷，实现清洁生产的需要出发，进行了无种子罐条件下酒精蒸馏废液直接全循环使用的自絮凝颗粒酵母酒精连续发酵实验研究，十三次全循环运行得到的实验数据，与无废液循环的实验结果相比，虽然平均发酵时间略增至30h～40h，但发酵终点酒精浓度仍达到12.5％以上，残还原糖和残总糖分别在0.70％和0.90％以下，说明循环积累物对发酵的影响有限，废糟液直接全循环使用的工艺技术路线可行。

And the level of E2 in the ethanol pharmaceutical preparation of drynaria group group was higher than the water pharmaceutical preparation of drynaria group.the levels of BGP in the normal group, water pharmaceutical preparation of drynaria group,ethanol pharmaceutical preparation of drynaria group were obviously increased as compared with the normal group P.
