The results show that a little amount of heteropolymolybdovanadophosphate can remarkably speed the degradation, the best conditions of the oxidative degradation of chitosan with hydrogen peroxide catalized by heteropolymolybdovanadophosphate in homogeneous condition are as follows: the ratio of catalyst and chitosan is 1 to 10, concentration of hydrogen peroxide is 0.15%, the temperature is 80℃, reaction time is 2h. 0.2g chitosan was degraded under the best condition and the molecular weight by viscometry was degraded from 1460000 to 7812. then water-soluble chitosan was obtained by this method; The heterogeneous method is a high efficient way, the best condition of this method are as follows: the ratio of catalyst and chitosan is 2 to 100, the volume of 30% hydrogen peroxide is about 3mL, the temperature is 90℃, reaction time is 5min~30min.
研究结果表明,适量磷钼钒的存在可显著加速壳聚糖的降解,磷钼钒催化过氧化氢均相氧化降解壳聚糖的适宜反应条件是:催化剂与壳聚糖的质量比为1∶10、过氧化氢百分浓度为0.15%、反应温度为80℃、反应时间为2h,在此条件下对0.2g溶解在100 mL 0.5%稀醋酸中的壳聚糖进行降解,可使壳聚糖的粘均分子量由原来的146万下降到七千多(7812),成为水溶性低分子量壳聚糖,从而达到应用的要求;在异相条件下以磷钼钒为催化剂催化过氧化氢氧化降解壳聚糖是一种高效快速的方法,此法降解壳聚糖的最佳反应条件是:催化剂与壳聚糖的质量比为2∶100;30%过氧化氢的用量为3mL左右;反应温度为90℃、反应时间为5min~30min。

I normally use quite a lot of light sources; I place them so I can highlight details of the scene. In this image I have used 13 lights: 4 omni lights as ambient lighting, 2 to highlight the form of the engine, 3 spotlights to highlight the back of the engine, 3 highlight to stress the specular and the greasy effect on the shell, a spotlight behind the snail neck for the sub surface scattering, in addition to the sun with area shade and the sky with a HDRI with an atmosphere similar to the photograph of the road for the global lighting I have used a surface with an asphalt texture for the floor and the yellow lines only to be reflected on the engine and to add some radiosity to the snail body and shine.
通常我使用很多的光源,我到处放置它们,这样我才能照到足够多的细节,在这幅图里我使用了13盏灯,4 盏点光源作为环境光,2盏来照亮引擎的形状,三盏聚光灯用来照亮引擎的背面,三盏来强调蜗牛壳的高光及油腻的感觉,有一盏蜗牛脖子背后的灯光来表现3S半透明效果,另外还有一盏太阳光来获得各个区域的阴影,以及一个赋予了HDRI贴图的sky,来作为全局光,我使用了一种沥青材质作为地面材质,并让引擎能反射地面上的黄色带子,并为蜗牛身体与光射线增加了一些radiosity,以取得得与背景类似的灯光环境。
