Using this theory, the flame structure of gas explosion in a horizontal pipe were studied, and the results show that: the gas explosion flame in a horizontal pipe is much thicker than that calculated from the former explosion theory, the intermediate products in the flame region are in separated state between the higher and lower level, and the cohesive force of the luminous body at lower level is bigger than that of the nonluminous body at higher level, there is a negative pressure region in the flame, and the flame splits easily in its propagating process.

结果表明，a水平管道内瓦斯爆炸传播火焰的厚度比以往理论计算得到的厚度大得多；b火焰区内爆炸中间产物呈上下分离状态，下部明亮发光体的内聚力比上部非发光体的内聚力高；c在火焰区内会出现负压现象；d火焰在传播过程中会发生断裂现象。

行星比一颗小行星或一颗彗星大的不发光的天体，由它绕转的恒星，如太阳的光所照亮在太阳系中有九个已知的行星：水星、金星、地球、火星、木星、土星、天王星、海王星和冥王星

Lawrence: the monthly recurrence known as the new moon with the old moon in her arms: the posited influence of celestial on human bodies: the appearance of a star (1st magnitude) of exceeding brilliancy dominating by night and day (a new luminous sun generated by the collision and amalgamation in incandescence of two nonluminous exsuns) about the period of the birth of William Shakespeare over delta in the recumbent neversetting constellation of Cassiopeia and of a star (2nd magnitude) of similar origin but of lesser brilliancy which had appeared in and disappeared from the constellation of the Corona Septentrionalis about the period of the birth of Leopold Bloom and of other stars of similar origin which had appeared in and disappeared from the constellation of Andromeda about the period of the birth of Stephen Dedalus, and in and from the constellation of Auriga some years after the birth and death of Rudolph Bloom, junior, and in and from other constellations some years before or after the birth or death of other persons: the attendant phenomena of eclipses, solar and lunar, from immersion to emersion, abatement of wind, transit of shadow, taciturnity of winged creatures, emergence of nocturnal or crepuscular animals, persistence of infernal light, obscurity of terrestrial waters, pallor of human beings.

莎士比亚出生的时期，在斜倚却永不没落的仙后座那三角形上端，一颗不分昼夜散发着极亮光彩的星辰出现了（这是两个无光、死灭了的太阳因相撞并汞合为白热体而形成的灿烂的新太阳）；大约在利奥波德。布卢姆出生时，出现在七星花冠星座里而后又消失了的一颗同一起源、亮度却稍逊的星宿；还有约于斯蒂芬。迪达勒斯出生时，出现在仙女座中之后又消失，小鲁道尔夫。布卢姆出生与夭折数年后出现于御夫座后又消失，以及另外一些人出生或去世前前后后出现在许许多多其他星座中而又消失了的、同一起源的星斗。日蚀及月蚀自隐蔽至复现的各种伴随现象：诸如风势减弱，影子推移，有翼者沉默下来，夜行或暮行动物的出现，冥界的光持续不减，地上的江河溪流之幽暗，人类之苍白。
