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.

By studying the inorganic CO〓 and helium isotopes in Yinggehai Basin, and investigating the Tertiary lithology and geothermal condition, combined with the results of thermal simulation test, it was suggested that inorganic CO〓 gas principally came from thermal decomposition of Tertiary calcareous shales and Pre-Tertiary carbonate under the burial depth of 6000m, approximately at a strata temperature of about 250℃.

通过系统地剖析莺歌海底辟带气田无机CO〓的碳、稀有气体同位素特征与第三系及古生界基底的岩性及热源条件，结合热模拟实验资料，认为无机CO〓主要来深埋的梅山-三亚组钙质泥岩热分解和前第三系基底碳酸岩的热变质，这种钙质泥岩和碳酸岩热分解产生CO〓的初始温度大约为250℃，相当于埋深约6000m。

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.

由于辐射陷获存在，有效辐射率是自然辐射率与透射因子（发射的光子在探测区域内没有被吸收的平均概率，它与吸收截面及激发态原子密度和空间分布有关）的乘积。5P3/2原子密度及其空间分布结合5P3/2 5S1/2跃迁线的碰撞增宽计算了透射因子，从而得到了不同He气压下，Rb D2线的有效辐射率。
