  • Carbon tetrafluoride | CF4 - PubChem

    The amount of adsorbed CF4 strongly depends on the pore size in nanotubes; at 1 bar the most efficient nanotubes for volumetric storage have size R = 0.68 nm. This size corresponds to the (10,10) armchair nanotubes produced nowadays in large quantities. For mass storage (i.e., weight %) the most efficient nanotubes have

  • CF4: Crystal Structure and Solid Phase Diagram

    The CF4☒Ar solid phase diagram shows a eutectic from about 12% Ar to essentially 100% Ar. The eutectic temperature is 70 ± 1&K, coinciding with the solidus line in the region of the eutectic

  • IR spectrum and radiative forcing of CF4 revisited

    3. Results 3.1. Experimental Measurement of Infrared Absorption Spectra [13] As shown in Figure 2, CF 4 has two IR absorption bands; an intense band at 1270–1290 cm −1 and a much weaker band centered at 632 cm −1.CF 4 has a high degree of symmetry and consequently a relatively simple IR spectrum. The intense sharp

  • 如何理解过拟合=高方差、欠拟合=高偏

    Translate this page2020-7-28欠拟合=高偏差还好理解一些,一直不太明白过拟合和高方差有什么关系,那么我们首先就要理解各种 ‘差’ 的定义定义:我们评价一个模型好不好,是通过测试集的数据来评价的,而不是训练集或者交叉验证集,如果在测试集上预测数据表现得不好,那么我们就说这个训练出来的模型有很大的误差。
