论文摘要
在这些注释中，我们对水平截面1平方米接收到的太阳能表达的公式进行计算，相对于纬度，倾斜度和当前日（数量也与太阳液磁通成正比）。根据纬度，我们还获得了一天中的一天，一天长度的可能性在一年中观察天顶的太阳的可能性（在这种情况下，在这种情况下发生的公式），可以观察到Oplar night/day night night night night night night and night night night night night night night night night night night night night night night night night night night night night night nightitude。第1节介绍了四个不同的角度，即倾斜，纬度，日间和小时。我们还引入了相应的旋转。在2中，我们将太阳的位置在天空中。能够计算以下节3个部分中的3个中的一天长度是成对独立的，除非依赖于5。在4中，我们计算了纬度，可以观察到或不观察到一个极性的一天或极地夜晚，并给出这些持续时间和结束的时间。在5中，我们在日出和日落之间整合了收到的太阳能，这使我们有一天收到的能量数量。在6中，我们整合了以下数量，以获取每年收到的能量数量。在7中，我们证明只有位于热带地区之间的纬度可以在Zenith观察太阳，并给出了一年内发生的两个瞬间。在8中，我们计算日出和日落的方向，鉴于高度和日期。
In these notes, we do the computation of the formula giving the expression of solar energy received by an horizontal section of 1 square meter, relatively to the latitude, obliquity and current day (the quantity is also proportional to the solar flux). We also obtain the formula of energy received during one day, of day length, of the possibility, according to the latitude, to observe the sun at zenith one day in year (and in this case, the formula of the day it happens), the possibility to observe a oplar night/day, and the time of beginning of these phenomenons according to the latitude. Section 1 introduce the 4 different angles which are obliquity, latitude, day and hour. We also introduce the corresponding rotations. In 2, we give the position of the sun in the sky. That make able to compute the day length in 3 Following sections are pairwise independent, except 6 which relies on 5. In 4, we compute for which latitudes it is possible to observe or not a polar day or a polar night, and give the time of beginning and end of these lasts. In 5, we integrate between sunrise and sunset the received solar power, which give us the quantity of energy received during one day. In 6, we integrate the following quantity in order to obtain the quantity of energy received per year. In 7, we prove that only latitudes located between tropics can observe sun at zenith, and give the two instants it happens in a year. In 8 we compute the direction of sunrise and sunset, given altitude and day.
