Especially in the biochemic separate industry,the aqueous two-phase extraction was obviously superior to the conventional extraction and separated methods.

双水相萃取技术是一种高效温和的新分离技术，在生物制药、分析检测、稀有金属分析等方面均有应用，特别是在生化分离工业中，比传统的萃取方法有着更加明显的技术和条件优势。

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。

MethodsThe content was determined by solvent extraction and acid dye colorimetiy, with Acanthoine Ruscope-ine （C16H22N4O2） as a control criterion and bromocresol green as the acid dye, and the wavelength was at 418 nm.

方法采用溶剂萃取酸性染料比色法测定，以去氢飞廉碱（C16H22N4O2）为对照品，溴甲酚绿为酸性染料，用氯仿萃取，检测波长418 nm。

In detail the process of the invention relates to a method for solubilising an oil-soluble pigment into an oil or fat by extraction of a solid preparation containing the oil-soluble pigment comprising the steps of a mixing the solid preparation containing the pigment with water, an extraction medium containing an edible oil or fat, and a nonionic surfactant having a hydrocarbyl group, an acyl group or a substituted hydrocarbyl or acyl group containing at least 6 carbon atoms; b optionally centrifugalize the mixture obtained and separate the oil phase.

具体而言，本发明方法涉及一种通过萃取含有油溶性颜料的固体制剂而使油溶性颜料在油或脂肪中增溶的方法，其包括步骤a将含有颜料的固体制剂与水、含有食用油或脂肪的萃取介质以及具有含至少6个碳原子的烃基、酰基或取代烃基或取代酰基的非离子表面活性剂混合，和b任选将所得混合物进行离心并且分离油相。

In order to analyze the airborne LiDAR data corresponding to single trees and stand heights in the forestry area, we set up samples to measure tree heights of Alnus formosana, Cryptomeria japonica, and Chamaecyparis formosensis in the Alishan area. We build the Canopy Height Model based on the data from the airborne laser scanning system. Single Tree heights were estimated by averaging the CHM values within a 0.5m radius, and six different sizes of sample stands (5×5, 10×10, 12.5×12.5, 15×15, 17.5×17.5, and 20×20) were set up to extract the average heights within the area as the calculated value.

本研究於阿里山地区设置样区，针对台湾赤杨、柳杉、红桧等树种进行立木树高之量测，配合该样区之空载光达影像资料，建立树冠高度模型(Canopy height model， CHM)，探讨空载LiDAR在森林地区对於单木树高与林分高的量测情形；单株立木高系以样区立木位置为中心，萃取0.5 m 圆形环框范围内之CHM平均值为其推估值；光达林分高则以6种林分面积(5 m×5 m、10 m×10 m、12.5 m×12.5 m、15 m×15 m、17.5 m×17.5 m、20 m×20 m)萃取范围内之CHM平均值为其推估值。
