Atractylodes lancea (thunb.) DC is a kind of geoherbs. The superior variety by the selecting of the A. lancea is vital to promoting production. In the present study, we had established the growth model for stem thickening, plant height increment and leaf area expansion using the logistic equation with four parameters. The growth parameters of four type's A. lancea were compared. The prediction on...
Reactive Ion Etching (RIE) is an effective method for etching of diamond films. In this paper, the influences of maskant, gas pressure and the composition of reactive gas on the etch rate and etched surface of diamond are studied. The patterned metal film used as hard mask plays an important role in etching process, it can be sputtered and re-deposited as metal oxides on the etched surface of diamond,...
