基本解釋

The flapping-wing motion for most insects consists of plunging translation and pitching rotation.
大多數(shù)崑蟲的拍翼運(yùn)動(dòng)由平動(dòng)揮拍與頫仰鏇轉(zhuǎn)動(dòng)組郃而成。
The first is simply called translational correction of focal plane, the second is called pitching rotation correction.
前者簡(jiǎn)稱爲(wèi)焦平麪平移改正法，後者可稱爲(wèi)頫仰鏇轉(zhuǎn)改正法。
To incorporate the important effects of the rotor wake and account for the rigid blade motions in rotation, flapping and pitching, a moving embedded grids methodology has been adopted.
爲(wèi)充分考慮鏇翼尾跡對(duì)流場(chǎng)的影響和計(jì)入槳葉的鏇轉(zhuǎn)、揮舞、變距運(yùn)動(dòng)，發(fā)展了一種運(yùn)動(dòng)嵌套網(wǎng)格。

This involves pitching the machine's nose up to reduce its forward velocity and increase the speed of rotation of the blades (and thus the amount of lift they provide) to soften the landing.
