It reduces the land use by about 50%. The adoption of heating of the fermentor by solar thermal collecting device helps avoid the second energy consumption.

减少土地使用50%左右，采用太阳能集热装置为发酵器加热，避免了二次能源消耗。

Finally, the second substrate covered with the second non-crystalline silicon layer is annealed with the laser with the second energy density to form the second polysilicon layer.

最后，以具有第二既定能量密度的激光对表面覆盖有一第二非晶硅层的第二衬底实施退火处理，以形成一第二多晶硅层。
