| Abstract: | Five items of chemical constituents of bamboo skin and bamboo meat were measured separately. The data of experiment was analyzed by using section estimation, hypothesis inspection and so on. Conclusion was drawn that the 5 constituents of bamboo skin and bamboo meat seem have little difference. The basic constituents are: water 11.3%, ash 1.04%, the extraction of benzene and alcohol 6.05%, cellulose 41.27% and xyloger 23.00%. Finally, the precision of the 28 groups data of the experiment was analyzed, according to which, the student's scores were given. |
