The effect of temperature on the mean kinetic energy of Oxygen, Ke(O), in silica hydrogel (constituting of water confined in a silica Xerogel matrix) was computed between 5 and 325 K. The results are higher by up to 40 % than those deduced from a recent deep inelastic neutron scattering (DINS) measurement. Note that when the mean kinetic energy of Hydrogen Ke(H) was computed using the same method a good agreement was obtained with the DINS measurement. This seems to indicate that the measured Ke(O) values are strongly underestimated due to the DINS method of analysis of the n-scattering intensities as discussed in the text.

水和二氧化硅水凝胶中氧原子的动能

计算得出温度对二氧化硅水凝胶（由限制在二氧化硅干凝胶基质中的水组成）中的氧气Ke（O）的平均动能的影响介于5到325 K之间。结果比那些高出40％由最近的深层非弹性中子散射（DINS）测量得出。注意，当使用相同方法计算氢Ke（H）的平均动能时，与DINS测量获得了良好的一致性。这似乎表明，由于本文所讨论的n散射强度的DINS分析方法，测得的Ke（O）值被大大低估了。
