1) leading edge profile
前缘剖面
1.
The effects of different leading edge profiles on the vortex flows over double delta wings were investigated both numerically and theoretically.
采用数值模拟和理论分析相结合的方法 ,研究了前缘剖面形状对双三角翼涡运动的影响 ,分析了前缘剖面形状对三角翼、双三角翼涡运动影响的不同机理 :对三角翼 ,尖前缘可以形成组织最好的涡结构 ,但对于双三角翼 ,圆前缘生成的旋涡结构较靠近翼面 ,涡结构紧密 ,诱导能力较强 ,可以形成有利的涡涡干扰 ,使内翼涡通过剪切层向外翼涡输入涡量更加容易 ,合并涡变得更加稳定 ,推迟了涡破裂 ,而且由于涡较靠近翼面 ,因而可以产生较高的非线性涡升力 ,这同传统的认识是不一致
2) sharp leading edge profile
锐前缘剖面
3) foreshore profile
前滨剖面
1.
Based on the repeatedly measured data including waves, currents, beach underwater tables and the foreshore profiles for every hour over several days in the Houjiang Bay of the eastern Guangdong coast, four significant canonical correlation variables, accounting for more than ninety percent of the total variance, were extracted by CCA.
利用在粤东后江湾多日逐时连续观测的近岸波浪、流、海滩潜水位和海滩前滨剖面地形数据,通过典型相关分析方法提取了占总方差90%以上的4个显著的典型相关变量,进而分别论述了常波况下海滩前滨剖面不同部位的地形动力过程。
4) leading edge of control surface
舵面前缘
5) front interface
前缘界面
6) front sectional elevation
前视剖面图
补充资料：关于solidworks 中的剖面线中的剖面线
solidworks的剖面线线型定义和autocad相同,它使用了autocad的剖面线定义方法,与autocad通用.因此,可以对剖面线进行定义. 方法:修改\SolidWorks\lang\chinese-simplified\sldwks.prn 用笔记本打开该文件,添加需要的线形.如 ;; Based on AutoCAD Ver.13.0s Hatch Pattern File ;;;; solidworks 区域剖面线定义文件 :: *金属, (Iron BrickStone), ANSI Iron, Brick, Stone masonry 45, 0,0, 0,.125 *塑料, (Lead Zinc Mg), ANSI Lead, Zinc, Magnesium, Sound/Heat/Elec Insulation 45, 0,0, 0,.125 135, 0,0, 0,.125 *玻璃,AR-GLASS@1.0 45,0,0,0,0.5, 0.5,-0.5 45,0,0.1414214, 0,0.5, 0.3,-0.7 45,0.1414214,0, 0,0.5, 0.3,-0.7 *软木, Cork material@1.0 0, 0,0, 0,.125 135, .0625,-.0625, 0,.35355339, .176776696,-.176776696 135, .09375,-.0625, 0,.35355339, .176776696,-.176776696 135, .125,-.0625, 0,.35355339, .176776696,-.176776696 *无, None 删除不需要的定义类型,可以大大提高solidworks 的启动速度
