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。

The results show that the turbulence intensity, fouling cleaning intensity and pressure drop increase with the increase of flow velocity, particle size and the volume fraction. The effect of liquid-solid fluidzed-bed cleaning fouling depends on the reasonable combination of flow velocity, particle size and the volume fraction. Through an integral consideration of water saving and energy saving and uniformity of fouling cleaning, the optimum flow velocity of flow, particle size and volume fraction are 2.0 m/s~2.5 m/s, 3 mm~4 mm and of 5%~8 vol%, respectively.

结果表明：流体的湍流强度、壁面污垢清洗强度和压力降均随流速、颗粒粒径和体积分数的增加而增加；液固流态化清洗防垢除垢效果取决于流速、液固颗粒粒径和体积分数的合理组合；综合考虑节水节能及污垢清洗的均匀性，高炉冷却壁的最佳流速为2.0~2.5 m/s，固相颗粒粒径为3~4 mm，体积分数为5%~8%。

paraquat is one kind of weedicide that comprehensive used all over the world ,for its little pollute to the environ accept a generally welcome .but the poisoning of paraquat have become a more and more severe problem,especially in developing county.the paraquat have a hypso-toxicity to human ,its mortality is 85%~95%.it show a multisystem injury to human body but the most serious injury of the paraqat to the viscera is lung .the mechanism of damnification is the great deal of super-oxygen ion procreant by paraquat in lung .at present the best technique to the diagonose of the paraquat poisoning to lung injury is ct.

百草枯是目前全世界范围内应用最广泛的除草剂，以其对环境的低污染性而受到广泛欢迎，但是百草枯中毒也随之成为一个越来越严重的题目，尤其是在发展中国家。百草枯对人体呈高毒性，死亡率约为85%~95%。百草枯中毒表现为多系统损伤，但是对人体脏器最主要的损伤是肺损伤，损伤机制主要为百草枯在肺组织内产生的大量超氧离子。目前对百草枯中毒致肺损伤的诊断最佳的方式是CT。

These are just some things which may help the individual with xeroderma pigmentosum to deal with their medical condition in the best way possible.
