| 7. | 3 . it studied the radiation problem of tlp , and paid attention to the computation of added mass and added damping about tlp which cylinders are set as regular polygon
3 .研究了张力腿平台的辐射问题，重点研究了浮筒柱正多边形分布情况下，总体辐射附加质量和阻尼系数计算问题。 |
| 8. | There exist only five polyhedra whose faces are all congruent regular polygons , and where the same number of faces meet at every vertex . this was disovered by the greek philosopher plato about 2 , 400 years ago
希腊哲学家柏拉图约在2 , 400年前已发现正多面体只有五种，因此这五种多面体便被统称为柏拉图方体。 |
| 9. | The chemical components of silkworm pupa crust were analyzed , and its microstructure was characterized by using scanning electron microscope . the existing realtion of among chitin 、 protein and inorganic salt in silkworm pupa crust has been observed . the results show that the major protion of silkworm pupa chitin is in pupa crust , and it accounts for about one forth of crust weight , the out surface of pupa crust is regular polygon net vein characteristics . chitin takes honeycomb shape in chitin - protein complex and conjugated with protein . the inner space of chitin - protein complex net was filled with inorganic salts . thus the theory basis was provided for working out the process route of isolation pupa chitin
对桑蚕蛹皮的成分、结构进行了化学及扫描电镜分析，确定其含有的主要成分及含甲壳素的数量，并对其中的甲壳素、蛋白质和无机盐三者之间的存在方式进行了观察.研究结果表明，蛹体中的甲壳素与灰分主要含在蛹皮中，甲壳素占整个蛹体成分的2 . 71 % ，占蛹皮重量的25 . 5 % ，蛹皮外表面呈规整的多边形网状结构，蛹皮中蛋白质与蜂窝状的甲壳素相结合，呈层状分布，颗粒状的无机盐填充在甲壳素/蛋白质复合物构成的蜂窝状的空隙中.这为制定提取蛹甲壳素的工艺路线提供了理论依据 |
