中—低—低变换工艺具有操作简便、蒸汽耗量低、触媒使用寿命长的特点。
The medium low low temperature shift process has the features of simple operation, low steam consumption and long catalyst service life.
在直线度测量数据处理过程中，运用坐标变换法时，往往不能一次正确估计“高—低—高”或“低—高—低”点的位置，所以需通过多次坐标变换才能达到目的。
As the data of straightness measurement are processed, Coordinate Transform method can not estimate the positions of High-Low-High or Low-High-Low correctly once.
