碳行星 的英文怎麼說
中文拼音 [tànhángxīng]
碳行星
英文
carbon planet-
The extreme carbon stars, whose derived mass loss rates and optical depths are both very high, are more evolved than infrared carbon stars. these stars are expected to evolve into protoplanatary nebula soon
極端碳星是高度演化后的紅外碳星，它的質量損失率及光深都非常高，幾乎沒有其光學對應體，並將很快演化為前行星狀星雲。Even after making generous assumptions, we determined that the maximum temperature reached in carbonaceous - chondrite asteroids with a diameter of 80 kilometers or more would be only 670 degrees c, too low to cause any melting at all
即使給予很寬松的假設，我們認為直徑在80公里或以上的碳質球粒隕石小行星，達到的最高溫度只有670 ，不足以造成任何的熔化。At the end of the process a carbon core of the star will be surrounded by a shell where helium is still being fused into carbon, which in turn is surrounded by and envelope where hydrogen is converted into helium
該過程結束時碳的星核會被一層仍然在進行氦聚變為碳的殼層包圍，而在這個氦-碳聚變層的外面還包圍著一層由氫-氦聚變層。After ten years dedicated work, quzhou modern charcoal co., ltd. has developed into a leading company in developing, manufacturing selling bamboo charcoal series products
公司創建於1996年，是一家專業從事竹炭碳應用研究生產銷售的行業頭企業，科技部國家星火計劃項目承辦單位。Moreover, water-vapor and carbon dioxide in the lower air absorb most of the infra-red radiation sent to us from the planets.
而且，較低空氣層的水蒸氣和二氧化碳能夠吸收行星傳播到我們這里的大部分紅外線。Why is this so important ? earth is of just the right mass to retain the heavier gases like carbon dioxide, nitrogen and oxygen in its atmosphere
在這生命帶中，像地球般質量大小的行星才得以保存大氣層和液態水，以地球來說，它的質量使它剛好維持大氣中較重的氣體如二氧化碳氮和氧。The helium will burn steadily and the higher energy production rate will heat up the star. the star will swell to a size even larger than a red giant and we have a
在恆星強大質量的約束下，核心氦聚變成碳的過程能穩定地進行，在核心高熱的煎熬下，恆星外殼會極度膨脹成為比紅巨星更巨大的分享友人
