circular orbit

基本解釋

And therefore, the total energy now is larger than the total energy that I had in my circular orbit.
因此，現(xiàn)在的,總能量比,在圓形軌道中要大。
So to go around this circular orbit will take the same amount of time as to go around this one, and that is by no means obvious.
沿著圓形軌道運(yùn)行的,時(shí)間和沿著橢圓軌道,所花費(fèi)的時(shí)間是一樣的，這決非顯而易見的。
E And so the total energy E which I've called the mechanical energy U always for a circular orbit is one-half U and is the same as minus the kinetic energy.
所以總能量,就是我說的機(jī)械能,總是圓軌道是1/2的,和減去動(dòng)能一樣。

You've got negative charge in motion, and it's in a circular orbit.
負(fù)電荷在運(yùn)動(dòng)，它們處在一個(gè)環(huán)形的軌道中。

The intervening weeks will be spent in a manoeuvre called aerobraking, which involves using the air-resistance of the thin Martian atmosphere to change the elliptical initial orbit into a circular one from which the planet's surface can be examined in detail.
