实际地

The first part concerned the self-conceptions of competence in the field of childrens physical exercise.

实验发现：1泛化经验下，小班幼儿对自己的跳远能力作出不切实际的高估，直接经验对此倾向没有显著的修正作用；中、大班幼儿在泛化经验下，对自己能力的估计相对保守，但在三次试跳后，也表现出高估倾向，但两者与其实际能力间都存在不同程度的显著相关，表明这种高估在学前中后期已具有一定的现实基础；2幼儿在多项目判断上比在单项目判断上更容易表现出能力高估，但多项目任务上对能力的程度判断，则0 细致地体现出幼儿对任务难度与能力间关系的理解和在自我能力判断中的运用。。

Now the controllability theory in linear systems over the field R of real numbers has been heavily studied. This theory is efficacious for analyzing the characters which are determined by the value of physical parameters and system structure, nevertheless a practical system has a definite structure and has approximate, even unknown parameter sometimes because of a limit to experiment conditions, or a limit to making technology, the errors of observation. It is inconvenience for a linear system over the field R of real numbers to analyze the structure characters of a physical system, such as structural controllability.

目前，实数域上的系统的完全能控性理论研究已经很成熟了，它用于分析系统结构和物理参量的值共同决定的那些性能是有效的，然而，在工程中，由于实验条件或者制造工艺上的限制和观测上的误差，以及人为地对数据的近似处理，一个实际系统往往其结构是确定的，而参数只是近似的甚至未知的，实数域上的系统不便于分析物理系统的结构性质，如结构能控性。

The main study in the paper is as follows: Firstly, discussing the purpose of carrying on hydropower units fault diagnosis, then, introduce state of the art and classical method in the field of fault diagnosis in hydroelectric sets. The mechanism, major failure and failure symptom of hydropower units, three methods that can identify unit's vibration fault. With the key technology of monitoring on hydropower sets together with the viberation signal-disposed and fault feature-extracted are analysised.

The paper analyzes the shortage of traditional roadway measuring wind method,and by theoritical calculation of measurement,the wind amount is tested,and the roadway fixed central point method of wind measurement and the roadway s average wind velocity fixed-point method of wind measurement are proposed,and which solve the problem of low wind velocity and low credibility well.

分析传统井巷测风方法的不足，并通过风量测定的理论计算和对现场风量进行实际验证，提出了井巷中心点定点测风法和井巷平均风速点定点测风法，较好地解决了当前测定风速慢、可靠性差的问题。

Have runners that the new track and surprisingly good weather, its results have practical help, won the 10 km senior men's champion Xie Xue said:"Today the weather is good, and the Island Eastern Corridor racing Road relatively flat, the roads are wide, a large number of runners than ever more crowded in the narrow tunnel detours much better, and this will also enable runners to dedicate even more success."

有跑手认为，新的赛道及出乎意料的好天气，对其成绩有着实际的帮助，夺得十公里男子高级组冠军的谢学文说：「今日天气相当不错，而且东区走廊的赛道较为平坦，路面亦阔，较以往一大批跑手挤于多弯路窄的西隧好多了，而且这也使跑手更专心地创佳绩。

The beheviour of four low-molecule weight organic acid lactic acid,hydroxy-acetic acid,mercapto-acetic acid,glyconic acid as iron-containing silicate-aegirines depressants on the hematite direct flotation is investigated in this paper.The results of flota
