二、建设内容：引进连续纺丝机和DCS集散控制系统，国内配套浸压粉机、黄化机、脱气装置、多效闪蒸及芒硝结晶装置等设备，以棉短绒为原料，建设年产2万吨棉浆粕及6000吨人造粘胶长丝项目。

We have developed a simple and easy-handling procedure for copper-catalyzed cyanation of aryl halides using K4[Fe_6] as the cyanide source. The present procedure has ligand- and base-free advantages, and was accomplished under the conditions of exposure to the air without degassing of the solvent.4. We carried out the selective control of preparation for phenyl ether and phenol from iodobenzene with 10 mol% of Cu_2·H_2O as the catalyst under the condition of exposure to air.

这个程序有无配体无碱的好处，并能够在暴露于空气的条件下进行，溶剂也不用脱气。4、空气气氛下，用10 mol%的Cu_2·H_2O催化碘苯偶联，实现了制备二苯醚和苯酚的选择性控制：即在有(来源：Aa955BC55论文网www.abclunwen.com)机溶剂NMP中实现了碘苯直接制备二苯醚的Ullmann反应，在H2O中实现了碘苯直接制备苯酚。

The specific gravity of degassed and undistilled beer sample plus real extract solution are determined in this method.The results of alcohol,real extract,original extract and real degree of attenuation etc.can be shown through the running of software program.

摘 要：通过测定脱气而不蒸馏的啤酒样品及浸出物溶液的比重，在开发的软件程序上运行后可得出酒精度、真正浓度、原麦汁浓度及真正发酵度等参数结果，该方法不需额外实验室硬件投入，比GB4928—91标准中蒸馏法测酒精度及原麦汁浓度含量提高效率8倍。
