treatise or encyclopaedic article on Astronomy, published in this country before 1864, where the superior limit of the eccentricity of the earth's orbit, as determined by Lagrange or by Leverrier, is given ; or even any reference made to the researches of these geometricians on the subject...
Mr. Johnson's great work on Logic goes steadily forward; and the later volumes increase in general interest owing to their more concrete subject-matter, whilst they have all the technical merits of the earlier ones. It will be remembered... BROAD,D C. - 《Mind》 被引量: 4发表: 1924年...

We obtain a simple equation that accurately describes the eccentricity that an asteroid or comet impact can cause in the Earth's nearly circular orbit about the Sun. It is found that the present eccentricity of the Earth could not have been caused or significantly altered by an asteroid or ...
The interaction between methanol and HZSM-5 surface was determined under different reaction conditions. It was found that the Lewis acid sites on the HZSM-5 surface played an important role in the conversion of methanol to hydrocarbons. During the catalysis process, methanol was adsorbed on the ...
