高校乒乓球教学中专项意识的培养

乒乓球的专项意识不是自发产生的 ,它是在大量的练习和比赛中获得的。学生在练习中不受正确的意识指导 ,就会受错误的意识支配。教师在教学中应注重对学生进行乒乓球专项意识的培养 ,加速运动技能的形成。

POLITICAL VIEWS OF THE RUSSIAN PEOPLE

The emerging political consciousness of the Russian people isanalyzed against a background of severe constraints in the Sovietera on public opinion formation. Problems in the transitionto democracy and representative government are reflected inheightened interest in politics, volatile levels of confidencein key political institutions, and deep uncertainty about thefuture in both economic and political terms.     

Environmentally-induced stone decay: the cumulative effects of crystallization–hydration cycles on a Lincolnshire oopelsparite limestone

An investigation has been undertaken at St Andrew’s church, Walpole St Andrew, Norfolk, to establish the underlying causes of the observed stone decay to the upper parts of the six stone piers. The stone decay was first recorded in the early 1930s. The salt-contaminated masonry within the church has been shown to undergo severe salt decay during the summer, with little damage occurring over the winter months. The south aisle piers have been shown to decay 2.5 times faster than the north aisle piers. Although crystallization–hydration cycles have been identified, the rate of decay is at its greatest when the cycling is relatively infrequent. This was not the expected trend. Furthermore, it has been shown that during extended periods where the ambient relative humidity is less than 75%, the rate of decay reaches a maximum. It is the length of this ‘drying’ period that apparently has the greatest influence on the rate of decay and could explain the significant difference in the rate of decay between the south and north aisle piers. The results have serious implications for passive conservation, where it is often recommended to lower the ambient relative humidity to well below the equilibrium relative humidity of the salt contaminant, to avoid crystallization–hydration cycles. Since, at the time of building, the church was situated on the coast, it is possible that the sodium chloride contamination occurred during the building process (1440–1520), particularly since the area was prone to sea-flooding at this time. Alternatively, the salt could have been applied as a treatment during the general restoration of 1897. Whatever the source of the salt, it seems likely that the ambient environment was changed by the insertion of a sealed floor in 1897, which could account for the onset of the salt decay.
