Especially the colossal magnetoresistance manganates La1-xCaxMnO3 , one of interesting materials in our lab, exhibited strongly CAPO at various doping concentrations (x=0, x=0.3 and x=0.58). However, several mechanisms about the generation and detection of CAPO have been proposed and disputed each other.

When the thickness of ITO was 210 nm, the Alq3 based TOLED exhibited a narrowed Electroluminescent peak at 536 nm with a full width at half maximum of 22 nm, of (0.229, 0.729) and an efficiency of 1.77cd/A. 2. With Alq:DCJTB/TBADN:TBPe/Alq:C545 as white light-emitting layer, RBG tricolor TOLEDS were achieved by adjusting the thickness of ITO. We obtained the peak wavelengths at 603nm, 475nm and 538nm, CIE coordinates of (x=0.513, y=0.360),(x=0.133, y=0.201) and (x=0.335, y=0.567), FWHMs of70nm, 30nm and 48nm for red, blue and green, respectively.

And shape by using X-ray to penetrate the log . The absorb of X-ray between log internal defect and log internal xylem is different .so the X-ray photograph is different .If we can get the several side X-ray photograph of log .and input the photograph into computer to digital image process . Then we can get the data and the location of log internal defect .

由于原木木质部分与内部缺陷部分对X射线的吸收能力不同，在X射线底片上形成的影像也不一样，如果对检测原木从不同的方向进行照射，再把得到的射线底片输入至计算机内部进行处理，就可以得到原木内部的大致空间结构参数，对原木的加工有重要的辅助作用。
