“课程思政”虽缘起高校,但思政内容与各学科融合的教育意义却为全学段所通用,初中阶段是青少年成才成长的“拔节孕穗期”,而语文作为兼具工具性与人文性的学科,与课程思政理念的有效融合能够为培养担当大任的时代新人起到独特引领作用。本文立足于课程思政融入初中语文的独特优势,以初中语文课程的特点为圭臬,提出发挥教师引领作用、合理挖掘思政元素、改变以往授课方式等教学策略,以期为课程思政融入初中语文教学实践提供有效的改革思路。

Based on the two-phase wet steam flow with spontaneous condensation, experimental verification and flow analysis on nozzle and 2D cascade are carried out. The 3D Reynolds-Averaged gas-liquid two-phase flow control equation solver is explored with k-e-kp turbulence model. Furthermore, 3D flow numerical simulation on the last stage stator of the steam turbine is carried out. The results show that a sudden pressure rise on blade suction surface is mainly caused by the droplet growth in condensation flow. The more backward the condensation position is in cascade passage, the less the sudden pressure rise from condensation is, and the larger the nucleation rate is, the maximum under-cooling and the number of droplets per unit volume are. Interaction of condensation wave and shock wave has imposed greater influence on the parameters of the blade cascade outlet.

This paper deals with the hydration of a blend of Portland cement and activated coal gangue in order to determine the relationship between the degree of hydration and compressive strength *** hydration process was investigated by various means:isothermal calorimetry,thermal analysis,non-evaporable water measurement,and X-ray diffraction *** results show that the activated coal gangue is a pozzolanic material that contributes to the hydration of the cement *** pozzolanic reaction occurs over a period of between 7 and 90 d,consuming portlandite and forming both crystal hydrates and ill-crystallized calcium silicate *** hydrates are similar to those found in pure Portland *** results show that if activated coal gangue is substituted for cement at up to 30%(w/w),it does not significantly affect the final compressive strength of the blend.A long-term compressive strength improvement can in fact be achieved by using activated coal gangue as a sup-plementary cementing *** relationship between compressive strength and degree of hydration for both pure Portland cement and blended cement can be described with the same ***,the parameters are different since blended cement produces fewer calcium silicate hydrates than pure Portland cement at the same degree of hydration.
