  1. The most obvious advantage is that because of their inability to scatter appreciably, nebular radio waves completely and genuinely delineate the distribution of nebular gas.

    因為波的散很小,所以最明顯的優點就是能夠全面而真實地勾畫出氣體分佈的外貌。
  2. In the absence of an appreciable magnetic field, the ensemble of nebular electrons interacts with ions to emit weak continuous radiation by free-free and free-bound transitions.

    在不存在可觀的磁場時,中的子系綜與離子相互作用可通過自由-自由和自由-束縛躍遷而發弱連續輻
  3. Radio astronomers are now able to synthesize the response of a partially filled aperture of large diameter and thus to map variations in nebular brightness.

    天文學家現在已經能夠把部分充滿的大直徑孔徑進行綜合,從而描繪出亮度變化圖。
  4. These sources are generally viewed in projection against radio nebulae representing the remnants of supernova outbursts.

    這類源一般都投影在超爆發殘骸的射電星雲上。
  5. Unlike the rapidly rotating neutron stars in the crab nebula and vela supernova remnants that are surrounded by dynamic magnetized clouds of electrons called pulsar wind nebulas, this neutron star is quiet, faint, and so far shows no evidence for pulsed radiation

    與蟹狀和船帆座超新遺跡中被磁化子云(脈沖)環繞的高速自轉中子不同,這顆中子安靜而虛弱,目前為止,沒有顯示脈沖輻的跡象。
  6. Which will eventually form stars of spectral types g, k or m. t tauri stars are surrounded by a huge cloud and they are very young, with low surface temperature. they emit most of their light in the infrared region and they appear red. a general principle is, a violent reaction will give out short wavelength waves, like gamma rays or x - rays ; while a gentle process will radiate long wavelength waves, like radio or infrared

    ,這類最後會演化為g k或m型恆,金牛座t型為表面溫度低而非常年青的恆,四周被所圍繞,所以這種顏色偏紅,較容易在紅外線波段找到一個普遍的原則是,如果活動越激烈,則所放出的光波波長越短,主要會為伽瑪或x線如果活動溫和,則會發放出如無線波或紅外線等長波長磁波。
