斜率

A new algorithm for tracing equiangular curves is presented to improve the machining quality of free-form surfaces.

了提高由曲面加工质量,提出一种等斜率曲线跟踪算法。

The respirometric activities of sludge before and after tame have been determined by the BOD Track, and the activity could be expressed by first slope of respirometric curve.

采用BOD测定仪连续测定了驯化前后污泥耗氧曲线,采用一段斜率表征污泥呼吸活性。并通过电镜观察驯化过程物相的状况。
