Morphing is the continuous smooth and natural transformation of a source object into a target object, where the object can be a numerical image, curve, surface, mesh, etc. morphing has very wide use in many areas, such as computer graphics, animation design, industrial modeling, science computation visualization, film stunt, etc. this paper makes researches on the morph of compatible planar triangulations and that of planar polygons, and the main results are as follows : 1 ) morph of compatible planar triangulations : this paper presents a convexity - preserving method for morphing compatible planar triangulations with different convex boundaries
變形，是指從初始物體到目標物體的連續、光滑、自然的過渡（這里的物體可以是數字圖像、曲線、曲面、網格等） 。變形在許多領域有著十分廣泛的應用，如計算機圖形學、動畫設計、工業造型、科學計算可視化、電影特技等。本文對同構平面三角網格的變形和平面多邊形的變形進行了研究，主要的研究結果如下： 1 ）同構平面三角網格的變形：提出了具有不同凸邊界的同構平面三角網格的保凸變形方法。 -
At the initial stage of planar technique, b was employed as ideal diffusion impurity in base - region of npn si planar devices because of the match of its solid - solubility and diffusion coefficient in si with those of p in emission - region, and the good shield effect of sio2 film to b. but because of the relatively large solubility ( 5 1020 / cm3 at 1000 ) and the small diffusion coefficient, the linear slowly - changed distribution of acceptor b in pn junction can not be formed, which could not cater to the requirement of high - reversal - voltage devics. thereafter b - a1 paste - layer diffusion technology and close - tube ga - diffusion technology had been developed, while the former can lead to relatively large the base - region deviation and abruptly varied region in si, which caused severe decentralization of current amplification parameter, bad thermal stability and high tr ; the latter needed the relatively difficult pack technique, with poor repeatability, high rejection ratio, and poor diffusion quality and productio n efficiency
在平面工藝初期，由於b在硅中的固溶度、擴散系數與n型發射區的磷相匹配， sio _ 2對其又有良好的掩蔽作用，早被選為npn硅平面器件的理想基區擴散源，但b在硅中的固溶度大（ 1000時達到5 10 ~ （ 20 ） ，擴散系數小， b在硅中的雜質分佈不易形成pn結中雜質的線性緩變分佈，導致器件不能滿足高反壓的要求，隨之又出現了硼鋁塗層擴散工藝和閉管擴鎵工藝，前者會引起較大的基區偏差，雜質在硅內存在突變區域，導致放大系數分散嚴重，下降時間t _ f值較高，熱穩定性差；後者需要難度較大的真空封管技術，工藝重復性差，報廢率高，在擴散質量、生產效率諸方面均不能令人滿意。 -
