查询词典 delta

In this paper, The delta wing of Mach number 0.8 at an attack angle of 21. 8 degree is simulated by our program. Then, using the visualizing program, we map the figures of space streamlines, cross streamlines near the vortex axis, three dimensional vortex lines, cloud atlas for pressure and vortex and targer of particles.

在这一章里，我们先用所建立的计算软件数值模拟了来流马赫数为0.8、攻角为21.8°的三角翼的流场，之后以拓扑分析结果做指导，研制了一套数值显示流场、旋涡结构的软件，用该软件我们绘制了跨音速三角翼背风区涡轴附近截面流线、空间流线、三维涡量线、压力和涡量云图以及粒子屏痕图。

According to calculation of obstacle degree, the obstacle factor of sustainable land use was analyzed in detail. The factors such as per capita agricultural gross output value, per unit area yield of grain, reed land rate, agricultural land rate and degree of townish are the main obstacle factor ofKey words: land use; sustainability; obstacle degree; The Yellow River Delta

研究结果表明：在34个因子中人均农业总产值、粮食单产、芦苇地占地率、农业用地率、城镇化水平是黄河三角洲可持续土地利用的主要障碍因素，其中芦苇地占地率在1996年以后始终是第一障碍因素，而人均农业总产值的限制主要出现在1998年之前，之后对可持续土地利用未构成障碍；粮食单产和农业用地率的影响主要出现在1996年以后；林草覆盖率、公顷耕地农机总动力和农村电气化水平在一半以上的年份对可持续土地利用构成障碍；在1994年之前，农民人均收入障碍度较大，是主要的障碍因素。
