緻密中心 的英文怎麼說
中文拼音 [zhìmìzhōngxīn]-
Remaining at the center of the vela supernova remnant is a pulsar, a star as dense as nuclear matter that completely rotates more than ten times in a single second
船帆座超新星爆炸遺骸的中心還存在著一顆脈沖星，它是一顆如原子般緻密的天體，一秒鐘可以自轉十次以上。In this paper, plasma - enhanced chemical vapor deposition ( pecvd ) technique was used to deposit the dielectric p - sio2 films and p - sion films on the silicon wafer under the conditions of low temperature and low pressure with teos organic sourse. this research was focused on the evaluation of film growth, hardness, stress, resistance and refractive index, by changing the experimental parameters including rf power, substrate temperature, chamber pressure, and the flow rates of teos, o2, n2. the results showed that the p - sio2 film was smooth, dense, and structurally amorphous
實驗結果顯示，用pecvd法淀積的p - sio _ 2膜是一表面平坦且緻密的非晶質結構的薄膜，與矽片襯底之間有良好的附著性；在中心條件時生長速率可控制在2600a / min左右；在基板溫度410時有最大的硬度可達16gpa ；其應力為壓縮應力，可達- 75mpa ；薄膜的臨界荷重為46 . 5un 。The gas must be far hotter than the dense matter at the centre of the sun for fusion to happen
要發生聚變，氣體的溫度必須遠遠高於太陽中心緻密物質的溫度。
