Since the Km〓 gene of pCS4 and pCS11 was derived from the mesophile plasmid pUB110 and coded for a thermolabile protain, it conferred Km〓 phenotype on the host cell at 48℃ only. Mutant Km〓 gene was obtained by selecting for Km〓 phenotype at elevated growth temperature. In this way improved vectors pCS5 and pCS12 were obtained, which can be used at 65℃ by Km selection.

利用提高培养温度后选择卡那霉素抗性表型的方法，从编码不耐热蛋白质的卡那霉素抗性基因出发，得到了提高其耐热性的突变的卡那霉素抗性基因，从而改造了CS4和pCS11，得到了适用温度达65℃的改进的载体质粒pCS5和pCS12。

In this paper, the law of microstructural change for heat resistant steels during long-term elevated-temperature service was discussed.

讨论了耐热钢在长期高温服役过程中微观组织结构的变化规律。

In comparison with the same products produced in the developed countries, the lower stress-rupture life at elevated temperature of steel T91 produced in our country is possibly due to the few knowledge of the chemical composition control, especially the minor element control in this steel.

我国在T91钢管的研究和开发过程中，对其化学成份的控制、尤其是钢中微量元素的作用缺乏认识，没有形成相应的工艺软件技术作为保证，因而与发达国家同类产品相比，国产T91钢管在高温长时持久性能方面存在着明显的差距，达不到国际水平。
