The influence of each condition on the reaction speed and yield was studied, and the optimal conditions were: the ratio of the amount of substance of aromatic amine and heptafluoro-isopropyl iodine was 1:1.1~1.5, the amount of substance of sodium dithionite, sodium bicarbonate, aniline compounds were respectively 1.1~1.3, the amount of substance of phase transfer catalyst TBAB and aniline compounds was 0.05~0.1, the concentration of aniline compound was 0.5~1.0 mol/L, reaction temperature was 10~20 ℃, and the solvent was aether.

最佳结果为：芳胺与七氟异丙基碘的物质的量比1：1.1~1.5，连二亚硫酸钠、碳酸氢钠与苯胺的物质的量分别为1.1~1.3，相转移催化剂四丁基溴化铵与苯胺的物质的量比在0.05~0.1，溶剂总用量使苯胺浓度在0.5~1.0 mol/L；反应温度10~20℃；溶剂采用乙醚。取代基供电子性越强，反应时间越短，产率越高；氨基的对位优先反应，氨基的邻位较难发生反应；且七氟异丙基总是优先取代在芳环电子云密度较高的位置上。

The ability of multiple lineage differentiation and long term self-renewal make stem cells to be the most important "seed cells" in future regenerative medicine and the best tool for the research in human early germ layer specification and organogenesis, drug screen and gene therapy.

干细胞具有的多向分化潜能和自我更新能力使其成为未来再生医学的重要种子细胞，并成为研究人类早期胚层特化和器官形成、药物筛选以及基因治疗的最佳工具。

It is important to enforce a health education and mental support for gravida. A scientific, systemized, integrated and individualized health education system for pregnant women should be established.

对妊娠期妇女实施健康教育和心理支持是必要的，应建立一套科学化、系统化、整体化的孕妇学校健康教育体系，使孕妇处于最佳身心和护理状态，以顺利度过妊娠期及产育健康的后代。

The experimental results revealed that papain, calcium chloride, compound phosphate, and glucide keeping humidity reagents intensify the tenderness of pork jerky, but the addition should be proper. The best proportion was papain0.4‰, compound phosphate 0.4%, calcium chloride 0.1%, and sorbitol 1.5%.

实验结果表明：木瓜蛋白酶、复合多聚磷酸盐、氯化钙和糖类保湿剂都可增加肉脯的嫩度，但用量应适当，添加量过大，反而使肉脯的感官品质变差；肉脯嫩化的最佳配比为木瓜蛋白酶0.4‰、复合多聚磷酸盐0.4%、氯化钙0.1%、山梨糖醇1.5%。

From the angle of development trend, the author believes that in the present age lacking of cosmopolitan authority but with limited order, sovereignty transference is the reasonable being during the transition stage of the world system. One of the essentials of the sovereignty transference is to confine the freedom of the national action felicitously in the fragmentized and homogenous world and seek the optimal point of equilibrium between the national and international interests.

从发展趋势看，主权让渡不会使国家回到传统的&主权封闭&，更不会使&主权消亡&，在目前这样一个没有世界性权威却存在有限秩序的时代，主权让渡是世界体系处于一种过渡阶段的合理存在，主权让渡的要义之一就是在碎片化和统一性的世界中恰当地对国家行动的自由进行限制，寻找国家利益与国际利益的最佳平衡点。

In this research, liposoluble chlorogenic laurate was synthesized by the acylation with lauroy chloride in the existence of alkali catalyst in non-water phase, and yellowish CGL powders with a yield of 81.24% were obtained under the optimal synthesis conditions determined via single-factor tests and orthogonal experiments, that is, carrying out the acylation at 35℃ for 8h with a n:n: n ratio of 1:1:1.5 and with dimethylformamide as the solvating agent and the thinner.

文中对绿原酸进行了改性，即在碱性催化剂催化的条件下使其与月桂酰氯进行非水相的酯化反应，得到了脂溶性的绿原酸月桂酸酯。经过单因素及正交试验，确定了最佳合成条件为：以N，N-二甲基甲酰胺作为溶解、稀释剂，绿原酸／月桂酰氯／三乙胺的摩尔比为1：1：1.5，温度控制在35℃，反应时间8h。

The quantizer can perform dynamic quantization for wavelet coefficients after the determination of the best quantization steps {qi} that minimize the average mean square error at a given bit rate.

在为DWT 系数确定好一组使给定码率下均方误差最小化的最佳量化步长{qi}后，该量化器将能够实现小波系数的动态量化。

The integrated fixed surface drive system and the controllable hydraulic trim tab system keep the boat optimal conditions at sea.

该艇采用集成化的固定式表面桨系统，配备液压可调的压浪板装置，使艇在风浪中航行、回转等状态时，仍能取得最佳航态。

Not only that, in China, the United States through the sound of singing the national or through the same Nationalization of the Bel Canto won the people's acceptance and love, in concert, stressed respiratory depth, the smooth voice, chest, oropharyngeal cavity, the first cavity resonance mixed Use, and the atmosphere of confrontation and support highs to close or cover up the use of methods to find the best conversion after the treble, and so on, are made consistent with the requirements of Bel Canto, but certain requirements such as the transport chamber music and highlight areas The national style and characteristics, make it more Singing the national flavor, and this is the U.S.

不仅如此，在我国，通过美声化的民族唱法或通过民族化的美声唱法同样赢得了人们的认同和喜爱，在演唱时强调呼吸深度、声音的通畅，胸腔、口咽腔、头腔共鸣的混合使用，气息的支持与对抗以及高音区运用关闭或掩盖的方法来找到转换之后的最佳高音等方面，均作出了与美声唱法一致的要求，但某些要求如旋律的运腔等方面又突出了民族的风格与特色，使之更具民族唱法的韵味，这便是美声化的民族唱法。
