The gallnut extract mainly comprises at least one of the following extracted compounds: Chinese tannin, five gallanilide glucose (1, 2, 3, 4 and 6-Five-O- gallanilide-Beta-D-glucose) and multiply gallanilide glucose (Six or Seven to twevel gallanilide glucose).

所述的五倍子提取物主要含有至少一种下列五倍子提取化合物：五倍子单宁、五酰葡萄糖(1，2，3，4，6-五-O-酰-β-D-葡萄糖)和多酰葡萄糖。

A method for cold transportation of goods that are placed in a hollow-walled refrigerating container, comprising the following steps: storage of a pumpable solution of tiny ice crystals, known as binary ice, having a given composition and temperature, in a binary ice store until said binary ice is used for refrigerating or filling purposes; the optionally filled wall of the refrigerating container that is to be used is emptied via an outlet valve for the binary ice; binary ice is allowed to circulate inside the refrigerating container via filling instruments that are supplied with binary ice from the binary ice store until the temperature of the wall drops to a given temperature, whereby the heated fluid that is discharged from the outlet valve is fed to a binary ice fluid store; the wall of the refrigerating container is filled with a given amount of binary ice; the refrigerating container is decoupled from the filling instruments; the binary fluid that result from the melted binary ice is returned to a corresponding binary fluid store in order to produce new binary ice from said binary fluid.

一种置于一中空壁制冷容器里的制品的冷运输用的方法包括下列诸步骤：将一种具有一预定的组成和温度的可被泵送的小的冰晶体的溶液保存在一个二元冰储槽中，直到所述的二元冰用于制冷或充填目的；通过一二元冰出口阀将待被使用的一制冷容器的随意被充填的壁排空；用二元冰充入该制冷容器的被排空的壁内；通过充填器具使该二元冰在该制冷容器里循环，这循环由来自二元冰储槽的二元冰供给，直到壁温下降到一预定值，从而从该出口阀放出的被加热的流体被提供给一个二元冰流体储槽；将一给定量的二元冰充入该制冷容器的壁里；从诸充填器具上拆离该制冷容器；将从溶化的二元冰形成的二元流体返回到一相应的二元流体储槽内，以便从所述的二元流体制取新的二元冰。

A method for producing fatty acid alkyl esters and/or glycerin comprising a step of bringing a fat or oil into contact with an alcohol in the presence of a catalyst, wherein the catalyst is at least one catalyst selected from the group consisting of the following to: a metal oxide having an ilmenite structure and/or a slyrankite structure; an oxide containing a metallic element belonging to the Group 12 and a metallic element belonging to the Group 4; a mixed oxide containing a metallic element belonging to the Group 12 and a tetravalent transition metallic element; a metal oxide containing zirconium and at least one metallic element selected from the group consisting of metallic elements belonging to the Groups 4, 5 and 8; and a metal oxide containing anatase type titanium oxide and/or rutile type titanium oxide, and the metal oxide containing a sulfur component of 700 ppm or less.

脂肪酸烷基酯和/或甘油的制造方法包括在催化剂的存在下使脂肪或油与醇接触的步骤，其中，所述催化剂是选自由下列～所组成的组中的至少一种催化剂：具有钛铁矿结构和/或斯里兰卡石结构的金属氧化物；含有属于第12族的金属元素和属于第4族的金属元素的氧化物；含有属于第12族的金属元素和四价过渡金属元素的混合氧化物；含有锆和选自由属于第4、5和8族的金属元素所组成的组中的至少一种金属元素的金属氧化物；和含有锐钛矿型氧化钛和/或金红石型氧化钛的金属氧化物，并且所述金属氧化物含有的硫成分为700ppm以下。

The present invention provides a method for preparing biodegradable and biocompatible, porous, polymeric scaffolds for tissue engineering, which comprises the steps of: dissolving a polymer in an organic solvent to prepare a polymeric solution; mixing an effervescent salt in the resulting polymeric solution to give a polymer/salt/organic solvent mixed gel; removing the organic solvent from the polymer/ salt/ organi c solvent mixed gel; and effervescing the salt in the resulting polymer/salt gel to yield a polymeric scaffold.

一种用于组织工程学的生物可降解和生物相容的多孔聚合物支架的制备方法，该方法包括下列步骤：在一种有机溶剂中溶解一种聚合物以制备聚合物溶液；在所得的聚合物溶液中混入泡腾盐，得到聚合物／盐／有机溶剂混合的凝胶；从聚合物／盐／有机溶剂混合的凝胶中除去有机溶剂；和在酸性溶液中浸泡所述凝胶以使所述盐泡腾产生聚合物支架。
