凸的

In 1936, J.Clarkson first introduced the concept of uniformly convex Banach spaces ,initiated from geometric structure of the unit sphere of Banach spaces to research the properties of Banach spaces, began to research convex theory of Banach spaces. The same year, J.

Clarkson首先引入了一致凸Banach空间的概念，开创了从Banach空间单位球的几何结构出发来研究Banach空间性质的方法，开始了Banach空间凸性理论的研究。

试验结果表明：竹叶青蛇腹鳞的超微结构由三角形微凸体、微孔和凹坑周期排列而成；腹鳞表面的平均摩擦因数为0.183，且与载荷无关；腹鳞的摩擦阻力主要是粘着力和微凸体变形的滞后阻力。

When the spine is focally kyphotic, particularly when there is a fixed kyphosis, or in the presence of anterior compression from a disc protrusion or spondylotic bar at 1 or 2 segments, an anterior surgical decompression (vertebrectomy or multiple discectomies) is indicated.19 Fusion and stabilization by means of an anterior strut and plate is also supported.27

当颈椎处于明显的后凸，尤其是僵硬性后凸，或者颈髓压迫来自前方的1到2个节段的突出椎间盘或椎间关节时，经过前方入路进行减压（椎体切除或多节段椎间盘切除）是合适的。融合固定的方法包括前方支撑和钉板系统固定。

Since the vertices of the simplex and the polyhedrons on the slices could directly be determined by the formulas, and the intervals of the variables in the polyhedrons on the slices were narrower, the algorithm was convenient and efficient.

由于单纯形和片上凸多面体的极顶点可以直接通过公式计算，且变量在片上凸多面体上的取值区间更窄，改进的定界阻止算法既方便又高效，这得到了一些经典算例和随机产生的算例的验证。

This paper introduces a new process in which the T-outlet flange is formed from the metal main pipe with spe-cial revolving draw equipment,makes certain the shape of prefabricating hole,and presents the simple for-mulas of calcu lating process parameters of hole.

The rapid back_and_forth grinding method was adopted in the precision machining of the curve point of the blanking punch, and the processing efficiency was effectively enhanced.

介绍了IC芯片管脚簧片精密冲裁加工中冲裁凸模的加工现状及存在的问题，在冲裁凸模曲线刃口的精加工中引入快速往复磨削加工方法可以有效提高加工效率，还分析了快速往复磨削加工的特征。

Also analyzes the mold of the main components (such as punch and die and dump devices, drawing punch, slates, Punch plate, etc.) design and manufacturing, stamping equipment selection, punch-gap adjustment and establishment of a vital parts machining process.

还具体分析了模具的主要零部件（如凸凹模、卸料装置、拉深凸模、垫板、凸模固定板等）的设计与制造，冲压设备的选用，凸凹模间隙调整和编制一个重要零件的加工工艺过程。

Because of the unique fitting mode of hydraulic drawing, early wrinkles of conical parts (very likely to wrinkle in ordinary deep drawing) fit orderly to punch under the action of counter pressure as the punch moves down ward, thus wrinkle-free parts can be obtained.

由于充液拉深方法独特的贴模方式，使普通拉深方法极易起皱的锥形件成形初期产生的皱随着凸模向下运动在对向液压的作用下顺次贴向凸模，从而可以得到无皱的零件。

The new method of CAD animation and the processing for drawing cam profile with flat-faced follower on the AutoCAD are discussed.

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
