PART 1 : DETERMINATION OF NON-VOLATILE MATTER, GRAVIMETRIC METHOD.

试验方法。第1部分：不挥发性物质的测定。

The results showed that sevoflurane was the most prevalent volatility halogenate anesthetics and had the highest concentration at sampling areas. All study hospitals exceeded the exposure limit for halogenate anesthetics (2ppm) recommended by NIOSH (National Institute for Occupational Safety and Health).The median level of N2O at the two medical centers was 1.87 ppm. Although regional hospitals seldom use N2O, its concentration was very high (median 120.85 ppm).

结果显示，Sevoflurane为使用最多之挥发性卤化麻醉剂，环境浓度亦最高，各医院均有高於NIOSH对於单一卤化麻醉剂暴露建议值(2ppm)的情形；医学中心笑气浓度之中位数为1.87 ppm，然区域医院虽极少使用笑气，环境中位数浓度高达120.85 ppm，有管路或开关阀泄漏之可能性。

The stable carbon isotope values of α-,β-,and γ-hexachlorocyclohexane isomers were determined by GC-C-IRMS,EA-IRMS,and Dual-inlet IRMS in this study.

应用GC-C-IRMS技术分析了水样品中α-和γ-六六六的碳同位素组成，结果表明六六六在溶解、稀释、萃取、挥发等过程碳同位素组成没有分馏现象。

The extracted components were qualitatively and quantitatively analyzed by gas chromatography mass spectrometry.The results showed that 30,26 compounds were identified from the volatile components extracted by DSE,SDE methods resp.36 kinds of components were extracted by 2 methods in total,among them the content of hexadecanoic aci...

结果表明，从DSE、SDE法提取的挥发性成分中分别鉴定出30(总含量58.24μg/g)、26种化合物总含量(86.66μg/g，2种方法共提取出36种化合物，其中十六酸含量最高，其次为亚油酸、油酸、邻苯二甲酸二异丁酯、间甲苯甲醛、龙脑。

Antimony samples were dissolved by aqua regia, hydrobromic acid, and hydrochloric acid step wisely, converting sulfur in the samples into sulfate.

方法采用王水，氢溴酸，浓HCl等试剂将锑样溶解，并使锑样中的硫转化为SO42-，低温加热蒸干，使锑完全挥发。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
