The proportion of the phase transfer catalyst and tertiary amine are usually in the range of about 1-5 and about 0.01-5.0 mole percent, respectively, based on total dihydroxyaromatic compound and dicarboxylic acid employed. In the second phosgenation step, the pH is raised to at least 10 and a stoichiometric phosgene excess of at least 5% is introduced.

The results showed that the soil configuration was improved by controlled irrigation, with increasing of root density in deep soil and sugar content of berry. Meanwhile the acid and salt content of the berry decreased and pH was modified. The wines had better aroma and flavor under controlled irrigation. 3825-4800m 3·hm -2 water per year was needed in controlled irrigation, saving 36% water compar...

结果表明，节水灌溉显著改善了土壤结构，增加了深层土壤的根系密度；提高了果汁糖含量，降低了酸含量和全盐含量，改善了pH值；提高了葡萄酒的感官质量，酒体丰满，香气浓郁，滋味更好；年灌溉用水量 382 5～ 4 80 0m3 ·hm-2 ，比常规灌溉节水 36 %。

Ammonium carbamate was found to be the best ammonia donor for the reaction and its favorable concentration is 120~160 mmolL^(-1). The optimal water activity, reaction temperature, pH value and concentration of D, L-HPGME are 0.55~0.75, 35~40℃, 7.5~8.0 and 40 mmolL^(-1), respectively.

The realized niche of SRB in the acidogenic-desulfate system is determined by its function; and the figure of three-dimension realized niche of its population is also presented, which is restricted by pH, ORP and ALK.

SRB种群的功能决定了它在产酸脱硫系统中的实现生态位，并给出了由pH值、氧化还原电位和碱度制约的SRB种群的三维实现生态位图。

The results show that perfect anatase nanocrystalline TiO2 can be obtained by SGRTSE method and the photocatalytic activity of TiO2 can be improved by doping and surface treatment. In the experimental system, the addings of proper salts are beneficial to the photocatalytic degradation of DBSNa. The pH value of solution, adding amount of TiO2, flow rate of air, and initial concentration are the main influence factors for the photocatalytic degradation of methyl orange, and the apparent reaction order is pseudo-first-order, which could be described by Langmuir- Hinshelwood equation.

结果表明：sol-gel法结合室温溶剂蒸发诱导可制备出晶型良好的锐钛型纳米TiO_2；过渡元素和稀土元素杂原子掺杂，贵金属掺杂和表面酸化处理是有效提高TiO_2光催化活性的途径；试验体系中，在DBSNa的降解过程中加入适量的盐，可以大大加速降解效果；光催化降解水中有机物，溶液pH值，TiO_2投加量，曝气速率，被降解物起始浓度等是影响降解效果的重要因素；对起始浓度较低的有机物光催化降解过程可利用简化的Langmuir-Hinshelwood动力学方程进行描述，反应级数为拟一级。

After the failure of achieving good enatioselectivity in asymmetric Baylis-Hillman reaction, we turned our attention to traditional chiral Lewis base catalyzed asymmetric Baylis-Hillman reaction.

我们还发现，用咪唑与-脯氨酸共催化醛和丁烯酮的Baylis-Hillman反应，但产物的e.e值还是很低，因此又回到了传统的用手性Lewis碱催化不对称Baylis-Hillman反应研究中。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
