为研究亚麻籽胶在低脂午餐肉中的应用，采用全质构分析、感官鉴评、扫描电子显微镜、动态流变学等方法，研究了添加单一亚麻籽胶和添加亚麻籽胶与卡拉胶的复配胶对低脂午餐肉的质构的影响。

In recent years there has been an increasing interest in introducing minimalistic models based on thermodynamic hypothesis that the native structure of protein is the one in which the free energy of the whole system is lowest.

近年来，许多研究者从事蛋白质简化模型的研究，这些模型基于热力学假说，即蛋白质的天然构象是自由能最低的构象。

As one of the most important philosophers and psychoanalysts, Jacques Lacan deconstructed the central status of self and the wholeness of "I", thus leading psychoanalysis study to a brand-new era.

作为法国当代重要的精神分析学家和哲学家，拉康解构了自我的中心地位，解构了主体，把精神分析学派带入一个新的领域。

The double half frame (HF2) was more superior to axial compression and anterior-posterior bending with stiffness characteristics. The bilateral frame was more superior to torsion and medial-lateral bending with stiffness characteristics.

双杆单边式构型(HF2)在抗轴向压力、前后弯曲力方面较突出，双边式构型在抗扭转力、侧方弯曲力方面较突出。

Based on analyzing the algorithms of Delaunay triangulation creation in domestic and abroad, in view of the situation of building DTM and the need of realizing railway 3D visual design, a divide-and-conquer algorithm to build DTM is presented, the algorithm use square grids to manage disordered points, to form triangular meshes in grids, DTM can be obtained by merging the triangular meshes, so that the work of sorting of the disordered points before building DTM is reduced greatly; moreover, the algorithm utilize subarea to control the vertices of convex hull so that the range which support points locate in can be predefined when searching support points, the workload of searching support points can be reduced and the speed of merging two triangulations is raised.

在分析了国内外构建DTM算法的基础上，针对DTM算法的现状及铁路线路三维可视化设计的需要，创立了一种构建DTM的分治算法。算法引入方格网管理离散点数据，在格中构建三角网，然后再将这些三角网合并形成DTM，极大地减少了构网前对所有参加构网的离散点进行排序的工作量。此外，通过对凸包顶点数据进行分区管理，在搜寻凸包支撑线时，能预先确定出支撑点的范围，减少了搜索工作量，提高了三角网的合并速度。

Laser-textured specimens exhibited lower and stable friction coefficient as compared with untextured specimens under dry friction. The textured surfaces also exhibited lower wear rate than that of untextured specimens. It was found that micro-dimples acted as traps for wear debris, and hence decreased abrasive wear.

在相同试验条件下与未织构面对比，织构面的摩擦系数均有不同程度减小且表现得更为稳定，并且磨损率也得到一定的降低，这是由于所制备的表面微坑起到了捕获磨屑的作用。
