氫核流
英文
hydrogen nuclei stream-
The prepared sdse modified zirconum meinbrane was tested at the wider range of tcmperaure and pressure and differellt composihons of hydrogen mixturc gases ( i. e. different hydrgen panal pressure ) in order to examine the performance of this membrane and the sole hpermselechvity of the membrane. the results showed tha the purity of the permeated hydrgen is l00 % at the base of the detection greatest lower lanit of the qhle mass spectrometer, and there was no impurity gas passed, the permeating flux and permeability of this membrane are from several decades times to one decade times more higher than tha of a palladum membran in the range of from 593k to 773k, puv = 0. 2 ~ 0. 3mpa, pdn = 4x l04pa - - 0. lmpa, the hydrogen permeatng flux is increased with the difference of the squto root of pressure, and presents a linear relationship, the pressure seems has no influence on the permeablity, the permeabi1ity is decreased with the increasing of the temperature, and presents an exponential relationship, accondng to the fitting curve of the relationship betwen the permeability and the temperatur derived from the experimenta daa, in the range of 593k ~ 773k, pup0. 2 ~ 0. 3mpa, pha = 4 x l0 # pa ~ 0
在更寬的溫度范圍、壓差范圍內，在不同原料氣組成（即不同的氫氣分壓）條件下，對所制備的鋯表面改性膜進行了滲氫性能實驗，考核了膜對氫的唯一選擇滲透性，結果表明：在四極質譜的檢測下限內，只有氫氣存在，而無雜質氣體通過；在593k 773k溫度范圍內，鋯表面改性選擇滲氫膜具有高於鈀膜數十倍至十幾倍的滲氫流量和滲氫系數；其滲氫流量隨著膜兩側氫分壓平方根摘要差的增大而增大，並且呈線性關系；壓力對膜的滲氫系數幾乎無影響；膜的滲氫系數隨著溫度的升高而下降，井巨呈指數關系：根據對實驗數據所作滲氫系數與溫度關系曲線的擬合，在溫度593k 773k范圍內，壓差p 、 0二0Matter will be transferred from the red giant to the white dwarf when the gravity of the red giant at its surface is weaker than that of the white dwarf. when sufficient matter is accreted onto the surface of the white dwarf, nuclear reactions will start and sustain for a short period on the white dwarf surface. enormous energy is produced
當紅巨星的表面引力比白矮星弱時，部分物質會盤旋流進白矮星內，當足夠的物質積聚在白矮星表面，便會燃點起熱核反應，產生出巨大的能量，這種爆發會維持下去，直至所有氫氣耗盡。Which turns four hydrogen nuclei to a helium nucleus. the star will have a convective shell and a radiative core just like our own sun see
進行，將四顆氫原子核結合為一顆氦原子核，恆星會有輻射核心和一個對流外殼就像我們的太陽。
