The anisotropy associated with the earth's rotation results in a slight deflexion of the ray paths . 与地转有关的不均匀性会导致波向线产生轻微的偏转。
prisms providing deviations ranging from about 15°to roughly 45°are available commercially. 市场上能买到的棱镜的偏转角大约从15到45。
The wake survey cannot be used to measure the drag of stalled airfoil or of airfoils with flaps down . 尾流测量不能用来测量失连状态下的冀型或襟翼偏转后的翼型阻力。
A variety of mechanical surfaces have been employed for deflecting the exhaust jets of solid-propellant rockets . 人们已经用过各种类型的机械控制面来偏转固体推进剂火箭的排气流。
When the pilot's control force acts only to deflect the tab, and not the main surface, it is designated a servo tab . 当驾驶员的操纵力仅使调整片偏转而不作用于主操纵面时,称为伺服调整片。
Bright areas reveal undeflected or stationary nodal regions while contour lines trace out areas of constant vibrational amplitude . 亮区表示未受偏转的或稳定的波节区而轮廓线则描绘出等振幅的区域。
the configuration has two tractor propellers, full-span double slotted flaps deflected 45°, and a high tail. 实验模型有二两拉力螺旋桨,全翼展双缝襟翼偏转45,并有高置的水平尾翼。
At supersonic speeds the control load acts mainly on the deflected surface itself, and hence has its centroid even farther to the rear . 超音速时操纵载荷主要作用在偏转面本身上,因此它的作用中心甚至更加靠后。
For any c.g. position, an increase in trim speed from any initial value to a larger one requires a downward deflection of the elevator . 对于任意一个重心位置,平衡速度由它的初始值变化到较大的值时要求升降舵向下偏转。
