In the language class studnts are usually given guidance for intensivereading but not always for extensire reading. Actually extensire readingplays an essential part in the foreign language learning *** shouldbe more important than intensive reading for post. intermediate andadvanced students, and for those who are using the language as a mediumfor another subject.

Using molecular dynamics simulations, we have revealed a novel wetting phenomenon with a droplet on composite structures formed by embedded water into(111) surface of β-cristobalite hydroxylated silica. This can be attributed to the formation of a composite structure composed of embedded water molecules and the surface hydroxyl(–OH) groups,which reduces the number of hydrogen bonds between the composite structure and the water droplet above the composite structure. Interestingly, a small uniform strain(±3%) applied to the crystal lattice of the hydroxylated silica surface can result in a notable change of the contact angles(> 40°) on the surface. The finding provides new insights into the correlation between the molecular-scale interfacial water structures and the macroscopic wettability of the hydroxylated silica surface.

根据表面活性剂溶液发生减阻时可放大近壁湍流涡尺度的特性,以及纵向微沟槽通过约束近壁流向涡运动实现减阻的机理,指出了两者在减阻机理上存在互补的可能性,并对两者的协同减阻性能进行实验研究验证,分析两者的协同强化减阻机理。通过研究0.22 mmol/L表面活性剂CTAC/NaSal溶液在两种不同尺寸的纵向壁面微沟槽通道内的变温度协同减阻性能,发现20℃时溶液能在纵向微沟槽的作用下强化减阻性能,最大减阻率从光滑通道的66%分别增大到G1沟槽的71%和G2沟槽的74%;减阻溶液的临界雷诺数及临界温度在G1沟槽通道内比在G2通道内小,但在G2沟槽通道内则与光滑通道的基本相同;微沟槽的减阻尺寸在减阻溶液中得到了放大;表面活性剂与纵向微沟槽的协同强化减阻机理在于表面活性剂放大了近壁湍流涡尺度,使微沟槽能约束住更多的近壁流向涡,同时也使微沟槽能在更高雷诺数下仍有减阻强化性能。

蒸汽-水膜直接接触冷凝界面能质传递机理是混合式冷凝器优化设计的基础,以蒸汽-水膜直接接触冷凝为研究对象,基于流体体积(VOF)方法构建了界面相变冷凝能质传递模型,分析了蒸汽质量流量(0.002~0.010 kg/s)、冷却水质量流量(0.30~0.83 kg/s)及流动方向对蒸汽-水膜直接接触冷凝换热的影响。结果表明:冷凝传热系数随蒸汽和冷却水质量流量的增大而增大,相较而言蒸汽质量流量对冷凝换热影响较弱;相比于顺流流动,蒸汽-水膜错流流动时换热效果较好,逆流流动由于相间作用力增加,水膜形状不规则,增大了水膜破碎风险。

预测慢性乙型肝炎病毒感染患者发生肝细胞肝癌(HCC)的风险在临床上具有重要意义.各种危险评分系统通过整合多种危险因素对患者进行风险评分可以达到较高的预测效果,但还需不断完善.近来研究发现,某些基因型及基因变异与HCC的发生相关,从而可以预测HCC的发生.既往认识的指标或一些新发现的指标如WFA+-M2BP可以单独或联合其他指标用于预测HCC的发生.随着研究的不断深入,将有更多的基因、指标及新构建的评分系统在临床上被应用于预测HCC的发生.
