Examples
- Actually , it is more environment - protective than existing surfacing since it contains no fluoride compounds
更环保,不含氟化物无损钛挂具 - A one - dimensional oceanic mixed layer model with the m - y level - 2 . 5 turbulence closure schemes is employed . the rate of energy loss by breaking waves is estimated by parameterization and incorporated into the model as a source of turbulence kinetic energy ( tke ) by modifying the existing surface boundary condition of tke equation . the velocity field and turbulence energy budget are calculated under different forcing conditions ( the results given below are for a wind speed of 20 m / s . )
采用一维2 . 5阶湍封闭混合层模式，根据参数化方法对波浪破碎导致的能量耗散率进行了估计，通过改变湍动能方程的上边界条件引入波浪破碎对湍动能生成的影响，计算了不同风应力强迫下的混合层流场结构和湍能量收支(下述给出的结果是取风速为20m s得到的) 。 - This paper generally introduced the present situation and domestic and abroad developing trends of surface treatment of stainless steel at present , analyzed the advantages and disadvantages of existing surface treatment technologies of stainless steel , pointed out that colored stainless steel have good prospect , concluded that laser surface treatment technology and ion implantation technology becomes developing direction of modern surface treatment of stainless steel
不锈钢表面处理的现状及目前国内外的发展动态，分析了现有不锈钢表面处理技术的优点和缺点.指出着色不锈钢有广阔的发展前景，提出了激光表面处理技术、离子注入技术将成为现代不锈钢表面处理的发展方向 - Another approach of this thesis is to demonstrate that the lowest degree is 5 in order to make the b - spline patches hold the property of local adjustment if no specific 111 abstract restriction to the partition . most existed surfaces reconstruction methods adopt bezier tool and demand particular partition . the local scheme addressed in this thesis does n ' t restrict the partitions of fitted surfaces , and the fitting tools is biquartic b - spline surfaces with double interior knots and biquintic b - spline surface with single interior knots
本文论述的“局部格式”调整方法不对剖分区域施加任何限制，主要采用内部具有二重节点的双四次b样条曲面和单节点的双五次b样条曲面做为拟合工具，给出了“局部”调整的方法，该方法能很好的保持拼接曲面的几何特征，克服了许多已有的重构方法仅采用简单共线法处理几何光滑性的弊端。
