Molecular diversity approaches based on the amplification, cloning and sequencing of 16S rRNA genes have revealed a variety of deep- sea archaeal, bacterial and picoeukaryotic lineages Comparative metagenomics of deep-sea archaea A-B Martin-Cuadrado et al 866 that are often very divergent from ...
太阳能在地面上的利用率不高,因为其会受到大气的吸收和散射,季节、昼夜更替的影响而___很多,能量密度变化也巨大,很不稳定,发展空间太阳能电站,可为地面提供商业化的、大规模的电力供给,解决人类对于稳定的可再生能源的长期需求问题。同时,空间太阳能电站的发展也将为更为长远的月球太阳能电站的发展[u...
Diurnal patterns of carbon dioxide, water vapour, and energy fluxes in pineapple [Ananas comosus (L.) Merr. cv. Red Spanish] field using eddy covariance We analyzed the eddy covariance measurements of momentum, mass, and energy taken daily throughout five consecutive seasonal courses ( i.e. 84...
falls as air warms and cools. Absolute humidity on the other hand has the exact dimensions of mass per unit volume, usually expressed as grams per cubic meter. In thermodynamic terms it is an intensive variable which acts as a force driving humidity variations in the direction of equilibrium....
The Relative Stopping-Power of Hydrogen and of Helium for Slow α-Particles An examination is made of reported experimental and theoretical values of the logarithmic mean excitation energy, l, for the stopping power of molecular hy... PN Cooper,VS Crocker,J Walker - 《Proc.phys.soc》 被引量...
Molecules of greater mass have a lower average speed than those of less mass at the same temperature. True or false? The mean speed of an ideal gas molecule depends on temperature and molecular mass. True or false? Materials with higher elastic modulus...
the uptake capacity was integrated covering the same exposure time with guaranteed steady state of the later reaction for the same mass of manganese oxide of the same kind. It was found the uptake capacity was dependent on the sample mass and exhibited a linear increase in the range of 0–8....
