The author would further argue for the theses listed below:(1) Wittgenstein's"phenomenological period"could be regarded as the beginning of his lasting interest in"the philosophy of psychology"into the end of his life, whereas the interest of this kind didn't appear obviously in Tractatus;(2) By interpreting the"atomic propositions"as the simplest description of the data instead of avoiding illustrating what it is as Tractatus did, Wittgenstein's "phenomenological period"does show us an amazing affinity between his own standpoint at that time and that of the Russellian logical atomism, which is surely under the influence of the empiricist tradition;(3) Wittgenstein's critique of his phenomenology, however, revives the celebrated Tractarian dichotomy between"unspeakablity"and"speakablity"in a new context by denying any attempt to employ any linguistic tool to designate or describe the absoluteness of the data which could be only"shown".

本文所试图论证的要点可以被概括为：(1)维氏的"现象学阶段"可以被视为他关于"心理学的哲学"的长期学术兴趣的发端点——这一兴趣一直延续到他生命的终点，却并未体现于其早年作品《逻辑哲学论》之中；(2)通过将"原子命题"解释为对于感觉予料的最简单的描述（而不是像《逻辑哲学论》那样回避对于"原子命题"之所是的正面解说），维氏的"现象学阶段"乃是向我们展现了他该时期的哲学立场与罗素的经验论版本的"逻辑原子主义"之间的令人惊讶的亲缘关系；(3)通过否认任何试图用语言手段来标示或描述予料的企图，并通过对于予料自身的绝对性的展示，维氏对于他自己的"现象学"观念的批判实际上乃是复活了他在《逻辑哲学论》时代就已作出的对于"不可说性"与"可说性"的二分法。

Traditionally, a surface is usually scatted in an array of 3D data points which are topologically connected by rows and columns to form a rectangular mesh. This method can't meet the requirement of description and measurement for some complex surfaces. On the basis of tracing border points, a new method is proposed to deliver 3D data points of surfaces, which are topologically constructed with optimum rectangular and triangular mesh. In order to measure surface efficiently and safely with NC machine, an optimization of measurement paths is proposed to avoid interference between the measuring tool and the surface with holes. The curve design is the basis of surface modeling.

数控测量技术的发展为测量自动化、集成化、智能化提供了可能，而对于复杂曲面的自动测量规划则是测量技术中的难点问题，平行截面等数目测点分布和四边拓扑测点分布规划方法，不论在测点分布的合理性上还是在网格结构的优化方面，均难以满足形状或边界较复杂曲面的离散化描述和曲面造型的要求，为了实现任意拓扑曲面的自动测量，本文对复杂曲面的合理离散化描述和自动测量问题进行了研究，提出了基于边界跟踪、优化网格的测点自动分布规划和四边、三角混合网格的生成方法：同时对具有孔洞或测量干涉凸台等非完整曲面的测量路径优化问题进行了研究，提出了路径优化方法。
