Organic solvent repetition crystallization method showed that 60% ethanol was the suitable solvent system. After 5 times repetition crystallization, the purity of product can be up to 98%, and the crystal state was yellow club-shaped, length of which is above 3mm. The productivity of this method is 30.01±1.26%, which is 2 times high than water repetition crystal method. So this method has good exploitation foreground.

有机溶剂重结晶法，选择60%浓度乙醇为适合的二氢杨梅素结晶体系，经过5 次重结晶后，产品的纯度可达98%，晶体为黄色、棒状，长度可达3mm，结晶产率为30.01±1.26%，较水重结晶法高2 倍左右。

The mechanism of co-fluorescence effect has been discussed. In chapter six, the new fluorescence enhancement phenomenon was observed by adding some crown ethers to samarium-thenoyltrifluoroacetone system.

在第六章中，研究发现当向钐-噻吩甲酰三氟丙酮中加入配位能力很强的大环配体冠醚时，冠醚对稀土有机配合物体系产生显著的荧光增强作用，其中冠醚二苯并18冠6后（DB18C6）可使钐-TTA二元配合物体系荧光强度增强280倍。

II. c. 2.(that second magna carta, and stable bulwark of our liberties) it is enacted, that no subject of this realm, who is an inhabitant of England, Wales, or Berwick, shall be sent prisoner into Scotland, Ireland, Jersey, Guernsey, or places beyond the seas;(where they cannot have the benefit and protection of the common law) but that all such imprisonments shall be illegal; that the person, who shall dare to commit another contrary to this law, shall be disabled from bearing any office, shall incur the penalty of a praemunire , and be incapable of receiving the king's pardon: and the party suffering shall also have his private action against the person committing, and all his aiders, advisers and abettors, and shall recover treble costs; besides his damages, which no jury shall assess at less than five hundred pounds.

并且，通过人身保护法案，查理二世第31年法案第二章（可以称之为第二部大宪章，我们的自由的稳定的防波堤）规定：本王国内的臣民，即英格兰，威尔士或贝瑞克（Berwick，以前属于苏格兰的郡；联合王国存在三种虽相近然而彼此独立有所区别的法律系统：英格兰，苏格兰和北爱尔兰法律系统，因而这部著作名&the laws of England&译成&英格兰法律&才恰当）的居民，不得将被监禁者遣送至苏格兰，爱尔兰，泽西，格恩西，或海外任何地方；（被监禁者在这些地方不能得到共同法的保护和利益）这样的监禁均为非法；任何人，若胆敢违背这部法律行事，应当取消担当任何公职的资格，应当得到警告，并且不能获得国王的宽恕：遭受监禁的人，可以起诉监禁者和他的协助者，他的建议者和教唆者，并获得损失的三倍补偿；此外，审判团对他的损失的评估，不得低于五百英镑。

Each beam starts out about as strong as the one in your laser pointer, but all together they end up pumping out 500 terawatts in two billionths of a second — roughly 500 times the entire peak power output of the United States.

每束光束刚产生时，强度仅跟你的激光指示器发出的激光强度一样，但是它们在二十亿分之一秒内，强度就能曾大到500太拉瓦，大约是美国能量输出峰值时功率的500倍。
