The inadequacy that exists in this domain is, the method that the three-dimensional parameter of clipper-built flow path changes the aspect that build a model exists to use a sex indeed mostly not strong, perhaps cannot be opposite model antrum curved surface undertakes parameter changes three-dimensional parameter of pilot defect; to change flow path model to not was aimed at its function feature to undertake differentiating, go against optimize a design further.

该领域中存在的不足是，流线型流道的三维参数化建模方面的方法大多存在着实用性不强，或者无法对型腔曲面进行参数化控制的缺点；三维参数化流道模型没有针对其功能特征进行划分，不利于进一步的优化设计。

Results show that the morphology of HNS changes from short plane-like shape to long plane-like shape when non-solvent temperature changes from 25℃ to 50℃. The morphology comes through the variety of ellipsoid, short plane-like and club-shaped with pH value of non-solvent from acidity to neutral and finally basical, with the particle size distribution in 50-300 nm, 50-500 nm, and 50-600 nm, respectively. Ellipse plane-like and long club-shaped morphology HNS were obtained using white dextrine and sodium carboxymethyl cellulose as surfactants in non-solvent, with the particle size distribution in 50-300 nm and 50-600 nm.

结果表明：非溶剂温度由25℃升高到55℃后，HNS晶体形貌由短片状变为细长片状；pH值由酸性变化到中性再到碱性时，亚微米HNS的晶体形貌经历椭球状、短片状、棒状的系列变化，粒度分布分别处于50~300 nm、50~500 nm、50~600 nm；白糊精和羧甲基纤维素钠作为晶形控制剂修饰后的亚微米HNS晶体形貌分别椭圆片状和长棒状，粒度分布分别处于50~300 nm、50~600 nm。
