Methods: The anterior chamber depth, lens thickness, vitreous chamber length and ocular axial length were measured for 270 eyes before and after cycloplegia. The corneal shapes of 136 eyes selected randomly from the 270 eyes were studied before and after cycloplegia by a computerized video keratoscope.

Taking a heavy truck cab as the example, a model of the spotweld space based on finite element was built to analyse the torsional stiffness of the model, and the amount and layout of the spotweld using the discrete variable topology optimization were optimized. Comparing with the original model in welding spot's number and the torsional stiffness, the optimized model has less number of welding spot, but the torsional stiffness of the two model is almost the same.

以某重型卡车驾驶室为例，在有限元模型基础上建立焊点空间模型进行扭转刚度分析，并采用离散变量拓扑优化方法对焊点的数量及空间布局进行优化，通过优化前后的对比可知，优化后在不降低扭转刚度的同时减少了焊点数目。
