低等

The modem new roll forming pipe systems remedy some defects of the traditional mills. They have lots of advantages such as meeting the productive in varied products, short time at changing the rollers, flexible and convenient adjustment, steady forming process and high qualities, etc.

现代新型的辊弯制管系统弥补了传统焊管成型机组的一些缺点，具有适应多种规格产品的生产，换辊时间短甚至不需要换辊，调整灵活方便，成型过程稳定，产品附加值高、质量好，同时轧辊磨损小，轧机能耗低等优势。

In this paper, the authors found the pyritized rod-like bacteria in desmocollinite and the Cyanophytes's gelationous sheath and the degraded organic matter of blue green algae in collinite of high-sulfur coal seams No.9 w(So=2.67% and No.10 w(So=2.54% using SEM-EDX and TEM. These findings of bacteria and algae suggest that they play an important role in the high-sulfur formation.

应用带能谱仪的扫描电镜和透射电镜，在乌达矿区高硫煤9煤层和10煤层的基质镜质体中发现了黄铁矿化的杆状菌落，在无结构镜质体中发现了蓝藻胶鞘及其降解有机质，这些菌藻类体的发现表明低等生源在高硫煤形成过程中起了重要作用。
