main sectional plane
main sectional plane 双语例句
The LED collimator element (1; 20) is designed to be asymmetrical at least with respect to a sectional plane (4) so that a defined non-uniform light intensity distribution is achieved in an emission plane (10; 26) of the LED collimator element (1; 20) which is orthogonal to the sectional plane (4) and to the main emission direction.
LED准直器元件(1；20)至少相对于准直器截面(4)被设计成不对称的，使得在LED准直器元件(1；20)的发射平面(10；26)内获得限定的不均匀光强度分布，此发射平面垂直于准直器截面(4)和主发射方向。
Using Miall`s architectural elements analysis, the reservoir architecture of Es234 subbed in ShengTuo oil field was researched. Twelve types of lithofacies were distinguished by core survey. Based on core survey, correlations of connecting-well sections and recognition of log curves, six scales of bounding surfaces were defined with the conception of stratification. By the recognition of lithofacies and the classification of sequences, eight kinds of architectural elements were identified. They were channel full sediment, channel retention sediment, sandbar, fall-siltseam, overbankfine, crevassesplay, chondro of flood plain facies. Finally the planar and sectional assemblage models of architecture of 34 sand body were established. Channel full sediment and sandbar were the main architectural elements in the plane and three hierarchies were divided in the section. The lower part was channel retention sediment; the middle part was channel full sediment and channel bar; the lower part was chondro of overbankfine.
应用Miall建筑结构分析法研究胜坨油田二区沙二段34小层砂体内部建筑结构：根据取心井岩心观察识别出12种岩相类型；通过岩心观察，连井剖面对比和测井曲线识别，采用层次分析的思路定义了6级界面；在岩相识别和界面划分的基础上划分出8种结构要素：河道滞留沉积、河道充填、纵向砂坝、横向砂坝、落淤层、越岸细粒沉积、决口扇和洪泛平原细粒；建立了34砂体建筑结构平面和剖面组合模式：平面以河道充填和砂坝为主，剖面上可分为3个层次：下部为河道滞留沉积；中部为河道充填和砂坝沉积；上部为越岸细粒沉积。
