  1. Three types of cuticular thickening at the polar region of the guard cells are observed : slight cuticular thickening ; rod - shaped culicular thickening and rarely t - shaped thickening. with data obtained from the former research and personal observation, the cladistic methods were employed for the phylogenetic analysis of data and trees were rooted by out - group comparison using, the related genus kadsura. as result, a new system of the genus schisamdra michaux was reconstructed, and schisandra michaux was subdivided into 2 subgenus, 3 section, 2 series 10 species in this dissertation

  2. This research is does using the glass fiber for the hillside makes up the strong strengthened material, mixes in the bolivian filament in the different hillside slope, the change hillside place intensity, improves regarding is easy to have the earth stone to flow local the hillside to give strengthens, with reduces the earth stone to cave in the after scope area, in has the after destruction regarding guard earth shi liu and the earth stone class to reduce to is smallest, after the process experiment data knew, mixes in bolivia truly to be allowed to strengthen the hillside place to the textile fiber the intensity, but mixes in the glass fiber to the too steep slope not to be big to its overall intensity help, after again comes is mixes in the glass fiber the hillside avalanche, proliferates the area comparatively originally not to mix in the glass fiber the area to be small

    摘要本篇研究是利用玻璃纖維做為山坡地補強的強化材，在不同的山坡坡度上混入玻璃纖維，改變山坡地的強度，改善對于易發生土石流地區的山坡地給予加強，和縮小土石坍塌后的?圍面積，在對于防?土石流和土石流發生后的破壞減到最小，經過實驗后的數據得知，混入玻璃纖維確實可以加強山坡地的強度，但對過于陡峭的坡度混入玻璃纖維對其整體強度幫助不大，混入玻璃纖維的山坡崩塌后，所擴散面積較原本沒有混入玻璃纖維的面積小。
