The invention discloses a 3, 5-2-0-(4-chlorobenzene chlorobenzene)-2-deoxidising- D-red-furanoside that contains alpha body and beta body. The method includes the following steps: dissolving chlorine indicant into tetrahydrofuran, quickly adding to alcoholic solutioin, whisking and reacting, after reacting, vacuuming and steaming solvent to gain mixture of alpha body and beta body, taking separation by column chromatography to gain separated alpha body and beta body.

本发明公开了一种3、5-二-O-(4-氯苯甲酰基)-2-脱氧-D-赤-呋喃糖苷，它具有式表示的α体和式表示的β体，制备方法采用在室温下，将氯糖苷溶于四氢呋喃中，然后快速加入到醇溶液中，搅拌下进行反应；反应结束，减压蒸掉溶剂，得到白色固体，将该固体用石油醚溶解，过滤除去不溶物，再次减压蒸去溶剂，得到白色α体和β体的混合物，用柱色谱法进行分离，得到单独的α体和β体。

结果表明： ZA27-4%Si合金阻尼随频率增大而减小，随温度升高而增大，阻尼不随应变振幅的变化而变化； ZA27-4%Si合金室温阻尼为5.83×10-3，与ZA27合金阻尼相当； ZA27-4%Si合金的阻尼是由合金内部的晶界和相界面滑动、位错振动以及各相的热膨胀系数和弹性模量间差造成的微塑性变形共同造成的。
