The effect from transverse webs and frames and the effect from collision velocity on ship bow collision properties are also studied in this paper. 7. The idea of buffer bow is put forward from aspects of the overall situation of environmental protection and reducing the damage of struck shipside caused by striking bow. The influence of curvature of bow shape on mode of distortion, collision force, collision force density and energy absorption of bulbous bow is described detailedly through a series of collision numerical simulation for bulbous bows that have different curvature.

发现横向框架对于船艏结构的变形形态，碰撞力及能量吸收都有一定的影响，在进行碰撞分析时不能忽略，在较低的速度范围内碰撞速度对碰撞力及能量吸收没有太大影响，所以可以从较高速度撞击后得到的能量吸收曲线中得到较低速的碰撞能量吸收曲线，从而可以得到低速碰撞时的撞深，然后通过这个撞深在较高速碰撞的碰撞力曲线中可以获得低速碰撞的碰撞力曲线。

It is a organic hexahydric weak acid. In different acidity, the dissociation degree and the color of reagent solvent were different also. Determined and draw the absorption curve of reagent in varies acidity, and figured out the dissociation constant by Perisic-Janjic method; the complex ratio of the reagent and bismuth was determinated by mole ratio method and continuous variation method; The apparent stability constant of the complex was calculated, the mechanism of dissociation and coordination were discussed.

2，6—二溴4—硝基偶氮氟胂是本实验室合成的测定铋的一个较好的试剂，对其进行了进一步的研究，在用柱层析法对其进行了提纯后，测定了试剂在不同酸华东师范大学硕：l：学位论文摘要度下的吸光度和最大吸收波长，绘制了其吸收曲线，用Perisic一Janjic法计算了试剂的六级离解常数；用摩尔比法和连续变化法测定了试剂与秘形成的配合物的络合比：计算了配合物的表观稳定常数，研究了其离解和配合机理，为筛选高效有机显色剂提供了理论依据。

While the proportion of pheophytin in total pigment concentration increased, the absorption peak in the blue region of spectrum deviated from 440 nm to near 412 nm. The absorption peak height in the blue region was mainly influenced by pheophytin concentration, whereas the height in the red was decided more by chlorophyll a concentration.
