Based on Fenton reaction and the auto-oxidation of pyrogallol, the anti-radical activity of morinda officinalis how was studied by spectrophotometry. The morinda officinalis how has obvious scavenging effects on hydroxyl radical and superoxide anion radicalO2(superscript - with the efficiency related to concentration of morinda officinalis how.

基於Fenton反应和抑制邻苯三酚自氧化原理，分光光度法测定体系吸光度的变化研究巴戟天抗自由基活性，证明巴戟天对羟自由基及超氧阴离子自由基O2(上标-均有良好的清除作用，清除率与巴戟天的浓度有一定的量效关系。

Oxygen-containing free radicals are produced when oxygen is not completely reduced to water in energy-producing oxidation reaction.

如果在物质氧化产生能量过程中，氧未被完全还原成水，可导致氧自由基的产生，氧自由基也可转变成一些非自由基氧活性物质。

The fourth part point out a series of actuality performance of abuse police administrative discretionary power,analyzing the reasons and its banes, on this foundation, put forward the necessity of control police administrative discretionary power.

第四部分指出了公安行政自由裁量权滥用的表现，分析了造成公安行政自由裁量权滥用的原因及其危害，提出了控制公安行政自由裁量权的必要性。

With a strong contemporary community who put sharp spearhead at Berlins negative liberty concept, and in some exaggeration in the form of negative and positive liberty is completely antagonistic to the freedom of contemporary misunderstanding of the community, this caused by including Habermas, Chantal.

然而，随着当代强势的社群主义者把尖锐的矛头指向柏林的消极自由观，并以某种过于夸张的形式把积极自由与消极自由的截然对立误解为当代社群主义——自由主义论战的实质，这在某种程度上引起了包括哈贝马斯、尚塔尔。

I have a dreamthat one day, down in Alabama, with its vicious racists, with itsgovernor having his lips dripping with the words of "interposition"and "nullification"-- one day right there in Alabama little blackboys and black girls will be able to join hands with little whiteboys and white girls as sisters and brothers.

我的祖国，可爱的自由之邦，我为您歌唱。这是我祖先终老的地方，这是早期移民自豪的地方，让自由之声，响彻每一座山岗。如果美国要成为伟大的国家，这一点必须实现。因此，让自由之声响彻新罕布什尔州的巍峨高峰！

In the second part, quantum chemical AM1 methods were employedto theoretically investigate the electronic structures of maleic anhydride in ground- and excited-states. On basis of the frontier orbital theoryand three bonding principles, the possibility of reaction of active α-hydroxysuccinic anhydride carbanion and active α-hydroxy-succinic anhydride radical on polymerization process of MArespectively by alkali catalyst and by hydroxyl radical was discussed. Theanionic and radical polymerization of MA discussed also. Theoreticalstudies show that both polymerization products of MA are in the chainstructures, corresponding to the experimental findings.

第二部分用量子化学AM1方法，计算研究了马来酸酐的基态和激发态电子结构；应用前线轨道理论和成键三原则分别探讨了碱催化条件下和羟基自由基引发下马来酸酐均聚合过程中α-羟基丁二酸酐碳阴离子和α-羟基丁二酸酐碳自由基活性中间体参与反应的可能性及由它们引发的马来酸酐阴离子聚合反应机理和自由基引发聚合反应机理；理论研究表明马来酸酐的均聚合产物均为链式结构，与实验事实相相符。

The extracts of water and alcohol were separated by ion exchange resin. The eluates of neutral solution were the most effective against hydroxyl radicals and the highest rate of inhibiting hydroxyl radicals was 81%. The eluates of basic solution were also effective, the inhibit rate of which was 60%.

将发酵灵芝粉的水和醇提取物上离子交换树脂柱，依次用酸性、中性、碱性淋洗液洗脱分组，发现中性洗脱部分对羟基自由基抑制作用最强，抑制率最高可达81％；碱性洗脱部分亦具有抑制羟基自由基的效果；酸性洗脱部分抑制羟基自由基的作用不强，且占很少比例。

Editor this segment Culture, Galileo's free fallers experiment Legend, was born in 1590 Pisa's Italian physicist Galileo, once in Pisa in free fall, two experiments of different weights from the same height and ball down, the ball at the same time, two of free fall, and found that the overthrow Aristotle first heavy objects will reach the ground with its head, the speed is proportional to the mass of the view.

编辑本段文化伽利略的自由落体实验传说1590年，出生在比萨城的意大利物理学家伽利略，曾在比萨斜塔上做自由落体实验，将两个重量不同的球体从相同的高度同时扔下，结果两个铅球同时落地，由此发现了自由落体定律，推翻了此前亚里士多德认为的重的物体会先到达地面，落体的速度同它的质量成正比的观点。

If a man is thought-free, fancy-free, imagination-free, that which is not never for a long time appearing to be to him, unwise rulers or reformers cannot fatally interrupt him....

如果一个人思想自由，幻想自由，想象自由，那么不自由的东西在他看来就绝不会长期存在。愚蠢的统治或改良者们不可能彻底妨碍他。。。。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
