It is demonstrated that the chiral quaternary ammonium salts catalysts exhibit promising catalytic properties for the substrate. Part III: The synthesis and the characterizing of the macroporous aminomethyl resin-supported cinchona alkaloid complexes and the study on its catalytic properties The part consists of two subsections. the macroporous aminomethyl resin -supported cinchona alkaloid complexes were synthesized by the stuff (cinchonine, quinine and macroporous aminomethyl resin). Their structures were characterized by means of elemental analysis, XPS, TG/DTA; the chiral polymer-supported complexes were first used as catalysts for the reduction of ketones. Their catalytic properties for the reduction processes were investigated. The comparison of the products e.e., the conversion of the substrate among different reduction processes was employed with determined by HPLC. The effects of the time, the temperature, the ratio of catalyst to substrate, reaction solvent as well as the recycle times were also discussed.
第三章聚-4-氨甲基苯乙烯负载金鸡纳碱金属络合物的合成与表征及其不对称催化性能研究本章分为两节,以辛可宁和奎宁及聚-4-氨甲基苯乙烯为原料,合成了4种聚-4-氨甲基苯乙烯负载金鸡纳碱络合物催化剂,并对它们的结构用元素分析、X-射线光电子能谱、TG/DTA等几种测试手段进行了表征;首次将所合成的手性高分子负载的金属络合物用于催化芳香酮不对称还原反应,详细研究了所得的手性高分子负载的金属络合物对不同底物的催化性能,用HPLC等分析手段定量检测了还原过程的底物转化率及其产物对映异构体选择性,并考察了反应时间、反应温度、催化剂和底物投料比、反应溶剂和循环次数对催化性能的影响。

In high-voltage var compensation field, when switching the capacitor banks by mechanical switch, it is easy to bound when it closes and to restrike when it opens, and the mechanical switch can not be switched frequently. When switching the capacitor banks by electronic switch in series, it needs dynamic and static voltage sharing circuit and synchronous triggering circuit. It leads to complex structure and high cost.
为解决当前高压无功补偿领域采用常规机械开关投切电容器组开关合闸时触点弹跳产生过电压,分闸时易重燃及不可频繁操作,而采用串联固态电子开关需要相应的动、静态均压及同步触发电路导致系统结构复杂且成本较高的问题,提出一种基于新型高压投切开关的高压动态无功补偿装置。

The upshot? Some venture capitalists are starting to resemble private equity investors , looking for fast growth from their more established portfolio companies instead of doing the spade work of assembling a management team, evangelizing a product, and building a market—tasks often associated with nurturing the fledgling companies that VCs typically target."Some funds have come out of the bubble and said,'We're going to go even bigger,'" says Bryan Roberts, a managing general partner at Venrock Associates.
结论是?某些创投家开始像是私募基金投资者,从他们许多已建好档案的公司中寻找快速成长的公司,取代组成一个管理小组,传播产品的好处,及建立市场这类型从事挖掘好公司的工作-这些工作常常时和培育刚开始营运的公司有关,这一型的公司是创投公司典型的投资目标"某些资金的梦想泡泡已成型,且说道'我们'将会变得更状大," Venrok Associates 的合夥管理人Bryan Roberts 说道。
