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。

Dot Pitch 点距 In monitors, the dot pitch is the distance between the holes in the shadow mask; the smaller the number, the sharper the image.

在监视器里，点距是距离(测量在彩色显象管阴罩过程中，在洞之间，用毫米)；更小的数目，骗子这幅图像。如果你有选择，A 。虽然，但是28毫米点距是更好的。

Second, compared with direct tensor product in multi-dimensional space, which suffers from the exponential increase of the number of sampling points with the number of variables, the Sparse Grid technique decreases the number of collocation points dramatically while the accuracy is guaranteed, and further reduces the computational complexity.

其次，为了避免通常用于多维空间的直接张量积随机配置法所带来的采点数随空间维度指数增长的缺点，采用稀疏网格采点技术，在保证建模精度的同时大幅度减少了配置点数目，从而进一步降低了随机配置法的计算复杂度。

By employing the Jordan-Wigner transformation and a modified mean field method, we are able to determine its ground-state quantum phase diagram approximately. The chapter IV is the main part of this Thesis. It contains the main innovations in our work. We propose and study in detail a S=1 Ising chain with the interplay of single-ion anisotropy and dimerization. The main results and innovations are the following: We show that the total number of the zero-component of spins at each site is a conserved quantity. This quantity, which may intuitively called as hole's quantum number, is hidden in the system. We show further that the hole's number in the ground-state is zero; By using the Jordan-Wigner transformation, we map this model onto a series of subsystems described by the spin 1/2 dimerized transverse Ising model. We solve the subsystems exactly, by presenting the exact wave functions and spectra;We show that this system exhibits a series of quantum phase transitions by varying the dimerization strength. We determine the quantum critical points exactly. We also show that the criticality is the same as that of the uniform S = 1/2 transverse Ising chain.

第四章是本文的重点及主要创新内容，我们具体研究了自旋为1的在横向单离子晶格场中的一维二聚化Ising链，我们得到的主要结果和创新之处是：(1)证明了这一模型具有一种隐藏的对称性，即自旋第三分量为零的格点数目是一个守恒量，并证明基态出现在空穴数目为零的子空间中；(2)利用Jordan-Wigner 变换将此模型变换到一系列自旋为1/2的横磁场中的二聚化Ising 模型，并给出了相应严格的波函数及能谱；(3)我们发现系统的基态随着二聚化强度的变化将呈现出一系列量子相变，我们得到了量子临界点的精确位置，并证明其临界性质与自旋为1/2的横磁场中的均匀Ising 链中的临界行为属于同一普适类。
