carbon nucleus 中文意思是什麼
carbon nucleus
解釋
碳核-
Since a carbon nucleus is six times more positively charged than a hydrogen nucleus, the cno cycle can only operate at the higher temperature and density provided by the more massive stars
但因碳原子核帶的電荷是氫原子核的六倍碳氮氧循環需要只有質量大星體所能提供的較高溫度和壓力才能維持。 -
According to the i - t curves of potential step, it was revealed that electrocrystallization of ni - w - b alloy on glassy carbon followed the mechanism of instantaneous nucleation and three dimensional growth with diffusion controlled. the crystal nucleus number on the surface of electrode raised by the increase of over potential
根據電位階躍的i t曲線分析得知，在玻摘要碳電極上ni wb合金電結晶過程遵從擴散控制瞬時成核三維成長模式進行，且隨著過電位的增加，電極表面上晶核數增多。 -
The forming - nucleus drive power could form numerous little crystal nucleus under natural melting temperature. the formation of tic particles in the melt could be divided into two phases which was forming - nucleus and growth. the forming mechanism of tic was : melting ti first surrounded c, then ti melting in the alloy and c formed a complicated reaction mesosphere on the carbon surface
根據熱力學及動力學分析，認為在碳顆粒界面處tic的形核率很高，形核驅動力足以在正常的熔煉溫度下形成眾多的小晶核；熔體中tic顆粒的合成可分為形核與長大兩個階段，其形核機制為：首先活性ti原子包圍c ，溶入合金中的ti與c在碳表面形成一復雜反應中間層，隨著反應進行， ti和c顆粒不斷減少，生成的tic不斷彌散分佈於熔體中；其長大過程伴隨著tic顆粒的相互堆砌、聚集和形態規則化。 -
To take place. in this reaction, three helium nuclei will fuse together to form a carbon nucleus
為止，即把三顆氦原子核結合為一顆碳原子核。 -
For example, the carbon - 12 nucleus contains 6 protons and 6 neutrons. the uranium - 238 nucleus contains 92 protons and 146 neutrons
例如，碳- 12的原子核內有6顆質子及6顆中子，而鈾- 238的原子核內便有92顆質子及146顆中子。 -
With the development of deposition techniques, diamond - like carbon ( dlc ) and a - sic : h films will be applied more widely. at present, the fundamental barrier that has not been overcome in respest of the coatings as applied to the irradiation environments is their radiation stability. for the sake of application to the fields such as aeronautics, astronautics, and nucleus reactorjnore attentions were paid on the investigation of the radiation stability of the films
隨著成膜工藝的日臻成熟，類金剛石（ dlc ）及a - sic ： h薄膜將得到更加廣泛的應用，為了使其應用於航天、航空及核反應堆中的某些關鍵器件，對這些材料的輻照穩定性研究相當重要，這是本文研究的根本出發點，也是國際上研究的熱點之一。
