its potential and maximal application field is for semiconductor films and optic films that mainly rely on the high-orientation and single crystal diamond films and big area transparent diamond films . but it is widely existent for defects in the process of diamond films growth and also it is difficult to get parameters stability such as temperature etc in wide area, as a result, the diamond films " orientation is changed, and it is very difficult to get the high-orientation and single crystal diamond films and big area transparent diamond films 金刚石膜潜在的最大应用领域是作为半导体薄膜和光学薄膜,而这个领域的开发在很大程度上依赖于高取向和单晶金刚石薄膜以及大面积透明金刚石膜的获得,但由于金刚石膜生长过程中缺陷的普遍存在以及大面积范围内均匀温度场等参数的难以获取,从而导致金刚石膜的取向发生改变,使高取向和单晶金刚石薄膜以及大面积透明金刚石膜的获得十分困难。
stability of main steam pressure is the foundation of the key parameter stability ( include the main steam temperature, the vapor pack water level, the oxygen content in the smoke etc . ) in the units, deb system increase the dependability and the economy greatly with the settlement of the energy's equilibrium between the boiler and the steamer 本机组利用先进的硬件设备dcs和优化的控制策略deb,圆满解决了机组协调控制系统中主汽压力稳定性及负荷适应性这一主要矛盾。主蒸汽压力稳定是机组一切关键参数(包括主蒸汽温度、汽包水位、烟气含氧量等)稳定的基础,deb系统解决了机组锅炉和汽轮机之间能量平衡,使机组可靠性和经济性大大提高。
