查询词典 randomized procedure

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。

"Cryoablation has been in use for many years," commented Dr. Georgiades. However, it is only in the past 9 years that the technology has led to probes small enough to be used percutaneously, with imaging now available to guide probe placement and to monitor the procedure."It is just now that we are, for the first time, establishing the safety and effectiveness of this procedure in kidney cancer," Dr. Georgiades told Medscape Oncology . Cryoablation is also used for other cancers, such as lung, liver, and bone, but there are few data on the effectiveness of cryoablation in these other tumors, he said.

Georgiades博士表示，冷冻疗法已经被运用多年，不过，只有在过去9年因为探针缩小才可以经皮穿刺使用，现在还有影像可以导引探针放置与监控手术；Georgiades博士向Medscape肿瘤学表示，这是我们现在有的技术，这是第一次建立安全与有效的肾脏癌手术；冷冻疗法也可用於其他癌症，例如肺、肝、骨癌，但冷冻疗法用於其他癌症的效果的资料不多。

If impurity or degradation product standards are unavailable, specificity may be demonstrated by comparing the test results of samples containing impurities or degradation products to a second well-characterized procedure e.g.: pharmacopoeial method or other validated analytical procedure.
