利用北京大学研制的BD-6型被动式超低频电磁探测仪在京热119井和168井附近布点探测，在探测过程中利用硬件滤波和水平旋转探头方向的方法消除了工频50Hz的部分谐波干扰，同时探测曲线的重复性也非常好，得到了相应井位的超低频电磁探测数据。

According to research on space between wheel and Cart rut traverse curve of single roadway, the width of strip slab was fixed. When there was horizontal loading on slab, contact state between strip slab and base course was studied, and finite element model was established. Comparing maximum principle stress among different load position on slab, it was found that the critical loading position of cement concrete strips pavement was the middle of longitudinal joint.

对车辆轮距和单车道轮迹横向分布曲线进行分析，确定轮迹板板宽；在有水平荷载作用时，对轮迹板与基层的层间接触状态进行分析，建立有限元计算模型，对比荷载作用在轮迹板不同位置时的最大主应力，最终确定水泥混凝土轮迹路面板的临界荷位为纵缝边缘中部。

The curve of expansion versus temper- rature in the temperature elevating process is depicted automatically and the coefficients of mean lin- ear expansion, instantaneous thermo-expansion, transforming temperature and softing point can be printed according to the.

The results show that, for the elasto-plastic contact of tip-substrate approach and separation process, the material plastic yielding in the atomic level is still governed by the von Mises criterion. For the adhesion of flat-ended wedges, continuum mechanics can be still applied down to a few lattice constants within the contact region, and give reasonable results, apart from the discrepancies near the contact edges. Moreover, adhesion hysteresis occurs during unloading due to the atomic steps, where the unloading curve does not coincide with the loading one. This in turn supports the presumption proposed by Pollock for the adhesion of stepped spheres.

本文首先对针尖—基体模型的弹塑性接触机理进行了深入研究，指出在原子水平上材料的塑性屈服仍由Von Mises准则控制；对平底锥冲头粘着接触的模拟表明，除了在接触区边缘附近有一定差别外，接触力学方法在接触区内几个晶格常数范围内仍能给出令人满意的结果；由于原子台阶效应，加载与卸载曲线不重合，出现粘着滞后，证实了Pollock关于具有纳米阶梯结构的球体粘着滞后现象的推测。

The edges of different organizations of every brain image are fuzzy and the MRI data is vulnerable to be affected by noise, therefore the non-brain region may be mistaken for brain region in the process of merging. In order to solve these problems, the Level Set method is adopted. The outline of the watershed is taken as the initial curves of level set to realize the automatic segmentation of brain tissue.

由于颅脑图像不同组织之间边缘模糊且自身容易受到噪声的影响，导致区域合并过程中可能会误将非脑组织作为脑组织合并，因此，采用水平集方法将初次分割获得的脑组织轮廓作为初始轮廓曲线，实现了脑组织的自动分割。
