However,there have been no papers which have investigated Minkowski and Minkowski slant helices and Minkowski conical geodesic curves so far as.In this paper,our major study is to give the definition of Minkowski general helix and Minkowski slant helices and Minkowski conical geodesic curves in indicators 1 in pseudo-Euclidean three-space (that is, three-dimensional Minkowski space), and study the definition of equivalence Minkowski general helix, By considering geometric invariants of these space curves, we can estimate the order of contact with those special curves for general space curves.

本篇文章主要研究在指标数为1的3维伪欧氏空间(即三维Minkowski空间)中，我们给出Minkowski一般螺线、Minkowski斜螺线和Minkowski锥面测地线的定义，研究Minkowski一般螺线的等价定义，给出Minkowski斜螺线和Minkowski锥面测地线作为三维Minkowski空间中的特殊曲线所特有的性质，并通过考虑三维Minkowski空间曲线的几何不变量，估计Minkowski斜螺线和Minkowski锥面测地线这两种特殊曲线和一般Minkowski空间曲线切触的阶数。

In addition, the blank holding force that is required to avoid wrinkle and rupture during conical part deep drawing is researched. The necessity of reasonable blank holding force in pressing is expounded. From the view of mechanical analysis, the wrinkle critical condition of side-wall is derived for the first time by the stress state of side-wall, the main deformation region on blank. According to the critical condition of plastic instability for flange, side--wall, corner of punch on blank, The blank holding force in conical part deep drawing is divided into four different regions within its forming figure. The basic principle of reasonable blank holding force during stamping is summarized and provided. The mathematical model of reasonable blank holding force that avoids the wrinkle and rupture is established and verified by the finite element numerical simulation and the grid experiment method. The result shows that it is accurate and reliable.

此外，本文还研究了圆锥形件拉深成形过程中，随着拉深变形过程的进行，毛坯为避免产生起皱、破坏缺陷而对压边力的需求情况，阐明了圆锥形件拉深成形过程中压边力合理变化的必要性；由毛坯主要变形区悬空锥壁部分的受力变形情况，从力学分析的角度，首次推导得出了圆锥形零件悬空锥壁起皱失稳的临界条件；并根据主要变形区法兰、悬空锥壁及凸模圆角部分的塑性失稳临界条件，在其成形范围图中，将圆锥形件成形过程中的压边力划分为四个区域；总结并提出了圆锥形件成形过程中压边力合理变化的基本原则；建立了防止起皱、破坏缺陷产生的压边力合理变化的数学模式，并得到了有限元数值模拟及网格实验法的验证，证实了理论分析结果的正确性和可靠性。

" The one hint of the future to be found among still familiar older senses of the word, such as "a thin skin or membranous coating" or "an abnormal thin coating on the cornea, is the sense of film used in photography, a sense referring to a coating of material, such as gelatin, that could substitute for a photographic plate or be used on a plate or on photographic paper.

在当中发现的对未来的提示仍然同这个词的旧有意思相近，例如"一层薄的皮或覆盖的薄膜"或"角膜上一种不正常的薄的覆盖物"，就是film 用于摄影的含义，意思指覆盖物，如胶，可以代替感光板或用于感光板上或在相纸之上。

Or .an abnormal thin coating on the cornea,.is the sense of film used in photography, a sense referring to a coating of material, such as gelatin,that could substitute for a photographic plate or be used on a plate or on photographic paper.

或。角膜上一种不正常的薄的覆盖物。，就是 film 用于摄影的含义，意思指覆盖物，如胶，可以代替感光板或用于感光板上或在相纸之上。

The excimer laser produces radiation with high photon energy which is capable of breaking the molecular bonds to ablate the cornea directly.

The researches show that the substrate plays an important role in the development of keratoconus. Cornea substrate's agenesis leads to the reduced solidity, which is possibly related to kearatoconus. There is still a lot to be researched on etilogy and early diagnosis of keratoconus.

虽有研究表明角膜间质的水平在圆锥角膜的发病中起重要作用，角膜间质发育不全，导致角膜的稳固性下降，可能与圆锥角膜形成有关，但对圆锥角膜形成的机理仍不详尽，因此，对圆锥角膜的发病机制及早期诊断的研究具有重要意义。
