三缝 meaning in English
trilete suture
Examples
- For specified three work positions as design inputs , the thesis evaluates their geometrical movements of the prime and sub - flaps , and some reasonableness are shown in view of kinematical geometry . the work can provide further aerodynamic analysis with variable wing geometrical data
以三缝襟翼的3个假定的工作位置作为设计输入，算出了3种不同轨道下襟翼的运动结果，并从几何角度进行了简单对比分析，为进一步的气动分析提供输入数据。 - Because there are small openings and the three cracksin the concrete lining of gas tunnel , the gas should intrude into the gas tunnel built . this effect will endanger the transport safety . the authors study on the operation ventilation technology in the gas tunnel and put forward an economical , safety and effective ventilation plan , and therefore furnish a theoretical basis for the gas tunnel ventilation design in the future
由于瓦斯隧道混凝土衬砌本体中的细小孔隙和“三缝”等缺陷的存在，建成后的瓦斯隧道必然受瓦斯侵袭，这对运营安全危害极大，为此，本文对瓦斯隧道运营通风技术进行了认真研究，提出了经济、安全、有效的通风方案，为未来瓦斯隧道的通风设计提供了理论依据。 - With the demands of designing the large - scale cargo airplane , in this thesis , many technical materials about the mechanisms of current wing flap types , of foreign transport airplanes are carefully studied at first , and the mechanical composition of three - gaps - fowler - flap is summarized technically about its major basic components , prime mechanism ( track ) , driving device , sub - flaps mechanism and the sub - flaps sequential control system
在本文中，针对大型运输机机翼设计的需求，首先对几种国外运输机襟翼运动机构的资料进行仔细研究，对三缝富勒襟翼运动机构的组成进行了分析，总结归纳出了三缝富勒襟翼运动机构的3个基本组成部分：主机构(轨道) ，驱动机构，子襟翼机构及子襟翼运动控制机构。 - Based on the kinematical design criterion of equi - chord percent ratio and spatial rigid body guiding mechanism , three theoretical design methods of arc track , non - arc track , and helical track are proposed in this thesis , meanwhile , different design methods about prime flap and sub - flap driving mechanisms are completed . three cases of different three - gaps - fowler - flap tracks are designed
对后缘三缝富勒襟翼工作时的3个关键位置，按照“等弦长百分比”运动的设计准则和空间刚体引导机构的设计思路，提出了圆弧轨道、非圆弧轨道和螺旋线轨道等3种空间位置引导轨道的设计原理，并分别给出主襟翼和子襟翼驱动机构的不同设计方法。
