本文通过对新晃县27所农村中小学(中学11所,小学16所)教室采光卫生指标的监测分析发现:虽然1988年(含该年度)以后建成使用的教室的投射角、开角、玻地面积比、采光系数的合格率均较1988年前的有所提高,玻地面积比的合格率已达至100％,投射角和开角的合格率虽也有较大程度的提高,差别分别有显著性(P<0.05)和高度显著性(P<0.01),但合格率仍然较低,致使采光系数的合格率较低,仅为35.7％。尤其是农村中学教室,虽然1988年后建成使用的教室的采光卫生指标合格率均有所提高,但除玻地面积比外,其它三个指标合格率均无显著性提高(P值均大于0.05)。这告诫我们:将教室采光卫生指标与基建工程同时设计、同时施工、同时验收,从而使采光卫生指标达到规定要求,保证教室有较好的采光照明实属必要。
Through the monitoring and analysis of the lighting index of classrooms in 27 rural primary and secondary schools (11 primary schools and 16 primary schools) in Xinhuang County, this study found that although the projection angle, open angle and glass of classrooms completed and used after 1988 (including the year) The area ratio and the daylight ratio of passing rate were all higher than that of before 1988, the pass rate of the glass floor area ratio reached 100%, although the passing rate of the projection angle and the opening angle also increased to a great extent, the differences were respectively There was significant (P <0.05) and highly significant (P <0.01), but the pass rate was still low, resulting in a low passing rate of the light coefficient, only 35.7%. Especially in the rural middle school classrooms, although the passing rate of the lighting and sanitation indicators of the classrooms built after 1988 has been improved, the passing rates of the other three indicators have no significant improvement (P> 0.05 ). This warns us: the classroom lighting health indicators and infrastructure projects at the same time design, construction, at the same time acceptance, so that lighting health indicators meet the requirements to ensure that the classroom has better lighting lighting is necessary.
