It is discovered that at a given latitude when a tilted flat surface at a fixed inclination varies with azimuth, a couple of particular orientations can be found at which the daily possible sunshine duration on the surface is unvarying all the year round, keeping at a constant value. The author defines this constant value as the Equal Insolation-Duration (EID), and defines the particular azimuth at which EID appears as the Equal-Sunshine Azimuth (ESA).The existentiar domains of EID and ESA are determined and the variation rules of EID and ESA with latitude and inclined angle are studied in this paper.

幼儿教师是学生学习阶段最初的启蒙教师，在幼儿成长过程中起着主导作用。本文从对幼儿进行独立生活能力的培养，组织幼儿集体教育活动及与幼儿进行情感沟通等方面的培养教育进行了探讨。幼儿教育不同与其他教育，它有一定的特殊性，作为一名带班老师，我是从如下几方面对幼儿进行培养教育的。 进行独立生活能力的培养：如今的幼儿在家中地位比较优越，他们家里所有长辈们的百般宠爱与呵护，所有事情长辈们都主动帮着操办。因此，

提高课堂效率先要提高学习兴趣，学习兴趣是学生主动学习的前提条件，教师在教学中要学会运用各种心理学知识，来调动和发挥学生的积极性，激发学生的兴趣，那样课堂效率才會提高。本人结合个人的教学体会谈谈如何提高小学生体育课堂效率。 通过设疑，感受兴趣：教师可以用提问的方式提出每堂课的教学内容，把教学内容变成一种疑问式教学，激发学生的学习兴趣，潜移默化的转变成活动的状态，从而调动学生的积极性，同时也使他们获
