松香脂的

We Factory export forest products as follows:Gum Rosin,Gum Turpentine(All products take to make by best,advanced and universal's a spectrum of steam method,and we severely differentiate material make into 100% Pinus Massoniana,Pinus Marsh,pinus elliotiis and Pinus mixed etc foru products),Pine Oil,Terpineol,α-Pintene,β-Pintene any rosins,Tung Oil,Cassia,Star Aniseed etc.our export have exceed 15years.

我司经常出口的林化产品有：脂松香、脂松节油（全部采用当前中国最先进和常用的连续蒸汽法生产，并严格区分原料生产出纯马尾松、湿地松、南亚松经合松四种产品）、松油、松油醇、α-蒸烯、β-蒎烯、各种树脂产品以及桐油、桂皮、八角等。其中，脂松香和脂松节油是我们的传统出口产品，已有15年的历史了。

State on quality of Chinese gum rosin from 1995 through 2002 was investigated in detail.

从各种不同渠道详细调查了1995年至2002年中国脂松香的质量状况。

As results, the contents of three original pimaric-type resin acids, namely pimaric, isopimaric and sandaracopimaric acids, generally decreased, the higher the initial content with the higher the temperature and longer time, the faster the content declined.

结果表明，脂松香中原有的3种海松酸型树脂酸即海松酸、异海松酸、山达海松酸的含量总体呈下降趋势，初始含量越高、热处理温度越高、时间越长，其含量下降幅度越大。

The morphological variation characteristics of resin acid ,as well as titration correction of the unsaponifiable matter during rosin saponification were discussed theoretically.

研究了在脂松香分析测定过程中影响松香不皂化物含量测定的关键因素及其影响机理，讨论了树脂酸在皂化过程中的形态变化特征及其导致不皂化物需要进行树脂酸校正操作和计算的理论依据。

Lianghe turpentine relative density, refractive index, initial boiling point, distillation range size, optical activity and chemical composition as well as the softening point, acid value, unsaponifiable matter content, ethanol insoluble matter, ash, optical activity and chemical composition and other physical and chemical characteristics of rosin gum were studied.

研究梁河脂松节油的相对密度、折光率、初馏点、馏程体积、旋光度和化学组成以及脂松香的软化点、酸值、不皂化物含量、乙醇不溶物、灰分、旋光度和化学组成等物理和化学特征。

These products are distilled and purified from gum rosin under vacuum and proper temperature, Used in electronic solder flux and as raw material for light-colored rosin resin, also used for ester gum.

该产品由脂松香在一定的温度和真空条件下经精制提纯而成；应用于电子助焊剂，浅色松香树脂及食用级酯胶原料。

Thirdly, the acrylic rosin was synthesized by the addition reaction from gum rosin andacrylic acid. The levo-pimaric acid was converted into acrylic pimarie acid throughDiels-Alder addition with acrylic acid. The abietic-type acids in the gum rosin were inisomerization balance under high temperature, and the abietic acid and palstric acid would beconverted into levo-pimaric acid and reacted in the later type.

第三，通过脂松香与丙烯酸加成合成了丙烯酸松香，该反应是左旋海松酸与丙烯酸发生Diels-Alder加成反应生成丙烯海松酸，由于脂松香中的枞酸型树脂酸在高温下处于异构化平衡状态，因此随着反应的进行枞酸、长叶松酸等会异构化为左旋海松酸参与反应。

By analyzing the situation of producing and selling of Chinese gum rosin ,the development of Chinese gum rosin industry can be divided into three main stages.

通过对20世纪90年代以来中国松香产销情况的分析，把中国松香行业的发展分为3个主要的发展阶段，并由此引出未来中国松香行业发展的趋势：松香生产必将逐步与松林基地结合，实现&林脂一体化&；热熔松香将在松香深加工过程中广泛采用；松香的国内需求将随着松香深加工产业的发展而迅速扩大。

The gas chromatography quantitative analysis conditions of gum rosin were studied by selection of chromatographic columns and chromatographic resolution conditions with the pure rosin sample of P.

用纯思茅松松香样品，通过选择色谱柱和色谱分离条件，研究确定了脂松香气相色谱定量分析的条件，定量分析了松香树脂酸的相对百分含量；定量分析数据通过统计学中的Grubb′s检验法进行误差检验，在确定的条件下脂松香气相色谱定量分析结果具有稳定性、准确性和复现性结果；对马尾松、湿地松松香定量分析也取得同样结果。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
