Design and manufacture of automobile panel die is a "bottleneck" in development of a new type of automobile. The assembly model is firstly introduced and described in this paper. Through 3D parametrization technology, a assembly model of drawing dies structure for a typical drawpiece selected from a series of automobile panels with similar topology was established, and the variant design of die structure was realized. As an example of front low crossbeam, the variant design of drawing dies structure based on the assembly model was successfully fulfilled. The research results proved that the method could greatly improve design efficiency of panel drawing dies structure.

Objective To compare spectacle magnification and visual acuity in highly myopic phakic eyes corrected by anterior chamber intraocular lenses (IOLs) and eyes corrected with spectacles.Methods A comparative study was conducted on the change in best corrected visual acuity before and after anterior chamber intraocular lenses were inserted in 44 eyes (26 patients) with high myopia from -9.875 to -24.75 D. Spectacle magnification (SM) in the myopic phakic eyes corrected with both IOLs and spectacle lenses was calculated....

Objective To compare spectacle magnification and visual acuity in highly myopic phakic eyes corrected by anterior chamber intraocular lenses (IOLs) and eyes corrected with spectacles.Methods A comparative study was conducted on the change in best corrected visual acuity before and after anterior chamber intraocular lenses were inserted in 44 eyes (26 patients) with high myopia from -9.875 to -24.75 D. Spectacle magnification (SM) in the myopic phakic eyes corrected with both IOLs and spectacle lenses was calculated. The actual results were compared to theoretical predictions. Results The BCVA of pre-operation and post-operation is 4.742±0.2435 and 4.911±0.1956 respectively. There was significant difference between the results (t=11.234,P=0.000). The result of spectacle magnification shows that phakic intraocular lens can magnify retinal image 15%~45% than spectacle in range from -10~-30 D myopia. There was positive correlations between magnification change and post-operative BCVA improvement (r=0.504,P=0.000).Conclusion Spectacle magnification is an important reason for improving BCVA in extreme high myopia. The phakic anterior chamber intraocular lens can improve BCVA by 1 or more lines.

目的评价高度近视眼在配戴框架眼镜和植入人工晶状体(intraocularlenses,IOLs)两种不同矫正方式中,透镜屈光力放大作用对术后矫正视力提高的影响程度。方法高度近视眼患者26例44眼,近视范围为-9.875~-24.75D,行有晶状体眼IOLs植入术,植入Verisys前房型IOLs,比较手术前后最佳矫正视力变化状况。同时,根据Gullstrand模型眼理论计算植入眼内的负度数IOLs与相应戴框架镜片状况下视网膜像放大率的变化,评价透镜的屈光度放大率与视力提高之间的关系。结果所有患眼的术前最佳矫正视力为4.2~5.0,平均为4.742±0.2435,IOLs植入后1个月的最佳矫正视力是4.5~5.3,平均为4.911±0.1956,两者差异具有显著性(t=11.234,P=0.000),IOLs植入术后最佳矫正视力明显高于术前框架眼镜的最佳矫正视力。根据IOLs的透镜屈光力放大率理论计算结果,屈光不正在-10~-30D范围内,植入的IOLs比框架眼镜的透镜放大率提高15%~45%,其变化值与最佳视力提高量有正相关关系(r=0.504,P=0.000)。结论透镜的屈光力放大作用是高度近视...
