The tropics are especially biodiverse, and because they start off with a higher number of species, it’s expected that they will also see higher rates of extinction. Even accounting for the increased biodiversity, though, the plant extinction rate in the tropics exceeded res...
Eleven normal early type supergiants and 11 M type supergiants have been spectroscopically confirmed in M 33. The visual extinction for the supergiants, de... RM Humphreys - 《Astrophysical Journal》 被引量: 950发表: 1980年 The integrated spectra of nearby galaxies - General properties and emi...
The dependence of the normal stress on the shear rate and magnetic field strength in the shear flow of magnetorheological (MR) fluids has been studied experimentally. An obvious normal stress could be observed when the applied magnetic field was higher than a critical value. The normal stress inc...
