For the DPPH free radical scavenging, their EC50 values are 19.05 mg/ml and 15.61 mg/ml respectively, but their anti-oxidant capacities are 40 to 60 % higher than fresh ones. Hot water extracts of Boehmeria nivea root experienced sun dry treatment have a better ability to scavenging ABTS free radical (EC50=34.16 μg/ml)when compared to that of fresh root, which only have one tenth anti-oxidant ability left.

经冷冻乾燥和日晒乾燥的苎麻叶热水萃取物其抗氧化成分较新鲜者低约55至67 %，而对DPPH自由基清除能力其EC50分别为19.05 mg/ml和15.61 mg/ml，相对其抗氧化能力却较新鲜者为高约40至60%；经日晒乾燥苎麻根热水萃取物其清除ABTS自由基能力(EC50=34.16 μg/ml)明显较新鲜者为高，显示其清除自由基能力只剩1/10。

The first part of this research was to investigate anti-oxidant abilities of Boehmeria nivea leaf and root. Different extraction methods, drying conditions as well as far infrared were applied to measure their effects on anti-oxidant abilities of Boehmeria nivea leaf and root. Results showed that 95% ethanol extracts of fresh leaves and roots demonstrate the highest anti-oxidant components(total contents of phenol compounds and flavonoids)and scavenging abilities free radical scavengingABTS(2,2'-azinobis［3-ethylbenzothiazoline-6- sulfonic acid］and DPPH (α,α-diphenyl-β-picrylhydrazyl) free radical , followed by hot water and cold water extraction.

本研究第一部份拟针对苎麻叶与根探讨其抗氧化能力，并以不同萃取方法、不同乾燥处理方式及经远红外线照射对其抗氧化能力之影响，研究结果显示，在不同萃取方法中，新鲜苎麻叶与根皆以95%乙醇萃取物的抗氧化成分及抗氧化能力清除ABTS(2，2'-azinobis［3-ethylben-zothiazo-line-6

The experiments for determining the mechanism and kinetics of catalytic pyrolysis reaction for a simple petroleum feedstock, were carried out in a batch micro-reactor using Daqing light gas oil. The results showed that carbonium and free radical reactions were the key reactions in catalytic pyrolysis. The carbonium ions were induced by catalytic reaction, whereas free radical reaction was predominantly due to thermal cracking.

首先在重油微反装置上考察大庆减压馏分油催化裂解反应产品分布，并将反应结果与相同温度范围内的热裂解反应相比较，二者的产品分布随温度等操作参数的变化规律明显不同，进而推断催化裂解反应过程为正碳离子反应机理和自由基反应机理并存；并建立了大庆减压馏分油催化裂解消失动力学模型，求得了化学反应速率常数。

The Christian Doctrin and cannot logically except Christianity unless they view CHrist, God, Sin and The Bible as a Good Concept and not a plan to get prepared for the Kingdom to come and Thats what I see many new age Christian doing taking bits and pieces from evry religion and running with a so called light but Christ is God in Carnate that came to set free and free endeed.

基督教逻辑doctrin不能例外，除非他们认为基督耶稣，上帝仲、圣经是一个好的构想，而不是一项计划，准备迎接前来王国thats什么，我看到许多基督徒做新时代以养生治与宗教和埃夫所谓轻，但基督是上帝carnate免费endeed来到放生。
