The simulated analysis results of the hybrid method are in good agreement with the results presented in the literature, which shows that the method is feasible and accurate. Finally, the hybrid method is used to analyze a side-fed offset Cassegrain antenna, and its radiation characteristics as well as its gain under wide-angle scanning are given.

与文献中已有结果的比较表明,文中的混合方法是可行和精确的,并采用该混合方法对一个侧馈偏置卡塞格伦天线进行了分析,给出了该天线的宽角扫描辐射特性和增益。

When a fighter aircraft or missile flies at high angle of attack,asymmetric vortexes are produced from the forebody and induce strong side force and yawing moment.

飞机或导弹在大迎角下飞行时会形成非对称涡,从而产生很大的侧滑力和偏航力矩。

When a fighter aircraft or missile flies at high angle of attack, asymmetric vortex es are produced from the forebody and induce strong side force and yawing moment.

飞机或导弹在大迎角下飞行时会形成非对称涡,从而产生很大的侧滑力和偏航力矩。

Slender body is a widely used forebody configuration for modern advanced fighters and tactic missiles.

现代先进战斗机和战木导弹常具有细长前体,大攻角条件下前体背风面会形成非对称涡结构,从而产生很大的侧向力和偏航力矩,这会严重影。。。

A detailed investigation was conducted in this paper on the flow asymmetry and its influencing factors over an ogive slender body model, incorporated with surface pressure measurement, skin oil flow pattern visualization, hot wire dynamic signal acquasition and other relevant approaches, in a low turbulence wind tunnel.

现代先进战斗机和战木导弹常具有细长前体,大攻角条件下前体背风面会形成非对称涡结构,从而产生很大的侧向力和偏航力矩,这会严重影响飞行器的可操纵性和飞行安全。

The sensitivity and specificity of far-infrared thermography in the diagnosis of lumbar disc herniation were evaluated. Compared with the normal, the thermogram of twenty-three cases on low back with LDH changed. They can be divided into four thermal patterns that is shuttle-liking (8 cases), discontinued in the middle line (6 cases), large regional (5 cases) and nonregular (4 cases) pattern. The temperature of abnormal sides is lower than the counterpart in most cases (nineteen of twenty-three). The thermography diagnosed LDH with sensitivity 90.48% and specificity 66.68%.

结果 F-IRT显示:23例LDH患者腰骶部热形态改变为四种形式:梭形,热区向一侧偏歪或呈角状突起(8例);夸中线热区不连贯(6例);骶髂骨上缘呈大片高温热区(5例);不规则形态(4例),患侧下肢较相对应的对侧胶体的温度,至少有一个患侧部位出现温度下降的有19例(82.61%),综合CT与F-IRT结果分析:F-IRT诊断腰椎间盘侧后突的灵敏度为90.48%,特异度为66.68%。

This lateral displacement can still be observed after the wind stops acting on the car, because it is rotated in plan with a non-null yawing angle.

这个侧向位移可能仍然被观察,在风停止行动在汽车之后,因为它在与一个非无效的偏航角的计划被转动。
