查询词典 helium

The variations of helium isotopic ratios can be observed in these xenoliths andxenocrysts from different area, or even from same area, indicating that the xenocrysts didntdirectly crystallize from basaltic magma, and basaltic magma is not directly related to thesemantle lherzolites xenoliths.

In helium atmosphere, the extract was pyrolyzed at 300, 420, 500, 600, and 800℃, separately. The pyrolysis products were directly introduced into GC/MS and qualitatively and semi-qualitatively analyzed. The extract was added into cigarettes as a flavor.

在氦气氛围中，将金银花提取物分别在300、420、500、600和800℃下进行热裂解，并以GC/MS对其裂解产物进行定性和半定量分析，并用金银花提取物进行了卷烟加香试验。

The is related to the frequency dependent absorption cross section and the density and spatial distribution of atoms in the lower level of the transition. Position dependent 5P3/2 state densities had been combined with the collisional broadening rate 5P3/2 5S1/2 line due to both helium and cesium perturbers to yield the .The effective radiative rates of the Rb D2 line as a function of the He pressure PHe were obtained . The fluorescence intensity I780 of the 5P3/2 5S1/2 emission was measured simultaneously.
