目的:探讨个性化牙龈成型器在不同牙龈生物型及角化龈宽度患者上颌单颗前牙种植中的应用效果。方法:选择2022年1月—2023年5月绍兴市口腔医院收治的行上颌单颗前牙种植修复的患者85例,按角化龈宽度和牙龈生物型分为4组,角化龈宽度不足和厚龈型组(角化龈宽度0.05)。永久修复完成时、永久修复完成6个月后,在相同牙龈生物型条件下,角化龈宽度≥2 mm的患者红色美学指数(PES)评分、龈乳头充填指数(PFI)评分、视觉模拟评分法(VAS)评分显著高于角化龈宽度<2 mm的患者(P<0.05)。在相同角化龈宽度条件下,厚龈型患者PES评分、PFI评分、VAS评分显著高于薄龈型患者(P<0.05)。术后3 d和术后7 d,在相同牙龈生物型条件下,角化龈宽度≥2 mm的患者黏膜肿胀度评分显著低于角化龈宽度<2 mm的患者(P<0.05)。在相同角化龈宽度下,厚龈型患者黏膜肿胀度评分显著低于薄龈型患者(P<0.05)。结论:种植体周围骨组织健康与角化龈宽度密切相关,牙龈生物型对种植体周围骨组织吸收影响较小。角化龈宽度充足且厚龈型患者软组织健康、龈乳头美学效果、软组织愈合程度及美学效果满意度更佳。

Acta Mechanica Sinica 2011年第4期27卷 510-518页

The Lattice Boltzmann method （LBM） is used to simulate the flow field in a bifurcate channel which is a simplified model of the draft tube of hydraulic turbine machine. According to the simulation results, some qualitative conclusions can be deduced. The reason of uneven flux in different branches of draft tube is given. Not only the vortex rope itself, but also the attenuation of the rotation strength is important in bringing on the uneven flux. The later leads to adverse pressure gradient, and changes the velocity profile. If the outlet contains more than one exit, the one that contains the vortex rope will lose flux because of this adverse pressure gradient. Several possible methods can be used to minimize the adverse pressure gradient domain in order to improve the efficiency of turbine machine.

以糙米为主要原料,采用挤压技术改性糙米粉。以糊化度为指标,在单因素试验的基础上通过响应面法优化改性工艺,并对改性前后糙米粉的特性进行分析。结果表明:最佳改性工艺参数为物料粒度120μm、水分添加量32%(以糙米粉质量计)、螺杆旋转频率30 Hz、挤压温度120℃,在此条件下改性糙米粉糊化度达到93.17%。与改性前相比,改性糙米粉水分、脂肪、淀粉和蛋白质含量降低;维生素B_(1)和B_(2)含量略降低。特性分析结果表明,改性后糙米淀粉颗粒表面变得平整,结晶度下降。
