meteoroid

音標(biāo)發(fā)音

Shortly before the uninhabited space station reached orbit in .May 1973,aeroaynamic pressure ripped off a meteoroid and heat shield.
在1973年5月無(wú)人空間站到達(dá)軌道前不久，空氣動(dòng)力壓力扯破了一個(gè)流星體和擋熱板。分析：首先，從邏輯上看，說(shuō)：“空氣動(dòng)力壓力扯破了一個(gè)流星體”，是不合事理的，荒謬可笑的。
When a meteoroid enters the atmosphere of the earth (becoming a meteor), it is actually the speed compressing the air in front of the object that causes it to heat up.
流星體闖入地球的大氣層（變成流星之前）時(shí)，由于高速飛行，它的前端與空氣強(qiáng)烈摩擦發(fā)熱。
Turn the globe by just a few hours earlier on that day in June and the meteoroid would have been over the border of Pakistan and India–exactly where everyone was fearing a nuclear attack.
如果六月的這天，地球轉(zhuǎn)動(dòng)退回到幾小時(shí)前，流星降落的地方就正好是巴基斯坦和印度的交界處，世人唯恐發(fā)生核戰(zhàn)的交界地。

Its micro-meteoroid protection is inadequate, so space-walking astronauts will have to install additional shielding, though not until 2004.
