x-plane

基本解釋

This photo shows smoke generators at work, providing visual feedback to researchers about airflow over the X-Plane.
這張照片顯示了在工作煙霧發(fā)生器，提供視覺反饋，不要過度的X -平面氣流研究員。
“First flight of a Navy unmanned X-plane -- that’s a huge deal, but it’s just one of the many firsts to come out of this program, ” Engdahl said.
Engdahl還說“這是海軍無人驗(yàn)證機(jī)的第一次飛行，這可是大事兒，但仍然僅僅是這一項(xiàng)目的開始而已”。
Objective To evaluate the feasibility and accuracy of real-time three-dimensional echocardiography (RT-3DE) full volume and X-plane for quantifying the volume of left ventricular (LV) models.
目的探討實(shí)時三維超聲心動圖（RT-3DE）全容積成像及雙平面法測量左心室容積的可行性和準(zhǔn)確性。

The first plane ever to fly faster than the speed of sound was the X-1 in nineteen forty-seven.
Another way to represent a point in a plane is I've got a radius and I've got an angle from the x-axis, right, and that's a standard thing you might do.
平面上面的點(diǎn)的方法,也就是極坐標(biāo),上面那種方法其實(shí)是，如果你們喜歡我這么說的話,笛卡爾坐標(biāo)表示法。
