Formula carries out the calculating of sun declination, and excursion is that -23.4 degree -23.4 are spent.It is uneven due to earth rotation, when causing the sun
The usually described time with us, and then day there is deviation with design, this time difference should include the consideration for calculating of sun position
Within the scope of.And usually described Beijing time there is following relation with us in local solartime：
T=t+e+ (L-120)/15, wherein t represent Beijing time, and L is the longitude for calculating place, and e represents described above
The time difference.
Solar hour angle H's is calculated as：H=15* (t-12)
The direct projection light that sun altitude refers to the incident ray of the sun deviates the angle of its horizontal component, is to calculate
The product of place latitude sine value and calculating place longitude sine value and calculating place latitude cosine value and calculating place longitude cosine
