The chemical separation and HF infrared absorption C/S instrument were used to determine total carbon and free carbon in titanium carbide powder.
采用化学分离与高频红外吸收碳硫分析仪相结合测定碳化钛粉中的总碳、游离碳 ,成功地解决了传统的重量法对于低含量碳测定存在较大的误差缺陷 ,同时使测定时间上大大缩短。
The￣(229)Ra activities were separated from irradiated target material by radiochemical separation technique.
用１４ＭｅＶ中子轰击钍靶，通过￣（２３２）Ｔｈ（ｎ，α）￣（２２９）Ｒａ反应产生￣（２２９）Ｒａ，由放射化学分离技术从被照靶物质中分离出￣（２２９）Ｒａ活性；利用γ（Ｘ）谱学方法，首次观测到了￣（２２９）Ｒａ的能量为１４。
