Two merging methods of Bézier curves are generalized to tensor product Bé zier surfaces, we propose two methods to approximate two pieces of adjacent tensor product Bézier surfaces by a piece of tensor product Bézier surface. We offer the explicit formulas of the merged tensor product Bézier surfaces with all kinds of merging conditions.

同样,Bézier曲线的两种合并方法也被成功的推广到张量积Bézier曲面上,得到把两片相邻张量积Bézier曲面合并成一片张量积Bézier曲面的两种合并方法,并给出在各种合并条件下的合并曲面控制顶点的显示表示式。

The research indicated that,the 36°Bè xylose mother liquor was used as material,9.60% catalyst M-16 was added,and after caramelized 180min at 120℃,a caramel...

研究表明,在36°Be′的木糖母液中,加入9.60%的M-16催化剂,于120℃下焦糖化反应180min,得到色率为2.8万EBC单位,红色指数达6.3以上的焦糖色素。

Theequivalence percolation resistance law is accurate enough to be used in productivitycalculation of horizontal well pattern.(3) Productivity of mixed well pattern of horizontalwell or multilateral horizontal well and vertical well is constructed and formulae are simpleenough to be used in the oilfield. The patterns include 5-spot pattern,7-spot pattern and9-spot pattern.(4) Productivity formula of united rectangular well pattern of horizontaland vertical wells is constructed. By this formula, the calculation results show that fora horizontal well length, there is a shape factor at which the productivity of the patternis biggest. So optimum method of the well pattern is proposed.(5) A new concept ofdimensionless length of horizontal well is advanced and the relationship of optimum shapefactor of the rectangular well pattern against dimensionless length of horizontal well ispresented. The influences of length of the horizontal well, area of the well pattern unitand the thickness of reservior are concerned.

利用该公式计算表明:当水平井长度一定时,存在一个最优井网形状,使得水平井的产能最大,在此基础上提出了水平井井网的优化方法;(5)提出了水平井无因次长度的概念,给出了联合井网最优井网形状因子与水平井无因次长度的关系式,并对水平井长度、油层厚度及井网面积对产能的影响进行了分析;(6)推导出了一无限水平井井排在XY 平面内势的解析解,为不同水平井整体开发井网或水平井和直井井网整体开发渗流理论的研究奠定了理论基础;(7)建立了交错式水平井与直井整体开发渗流理论,给出了拟三维条件下井网产能的精确解析解及该井网最优井网形状因子与水平井无因次长度的关系,并对产能的影响因素进行了分析;(8)建立了水平井与水平井正排列井网、交错排列井网条件下渗流理论及井网产能在拟三维条件下的精确解析解,给出了交错井网条件下最优井网形状因子与水平井无因次长度的关系,通过与正方形井网对比,说明优化井网可大幅度提高开采效果;(9)建立了分支水平井和直井面积井网水油两相非活塞驱替条件下渗流问题的解析解,给出了见水前后无因次产量与无因次时间的关系式以及见水时间等。
