常見例句雙語(yǔ)例句It must be presented as a function of hour angle and declination of sun. By this reason, a receiver must continuously change its position with the move of sun at sky in a day.指出焦線位置是太陽(yáng)赤緯和時(shí)角的函數(shù)，因此吸熱器必須隨著太陽(yáng)的周日眡運(yùn)動(dòng)而不斷改變位置。How to complete the calculation of sun declination , sun right ascension, sun greenwich hour angle, greenwich hour angle of aries and sun local hour angle in Astronomical Position.利用計(jì)算機(jī)完成天文定位中的太陽(yáng)赤經(jīng)、赤緯、太陽(yáng)格林時(shí)角、春分點(diǎn)格林時(shí)角、測(cè)者地方時(shí)角的計(jì)算。Especially, the importance of reducing the declination angle of antenna was emphasized and the effects of adjusting antenna declination angle on reducing homo-frequency interference were expounded.特別提出了減小天線下傾角的重要性，以及天線下傾角調(diào)諧方式對(duì)減少同頻乾擾的作用。 返回 declination angle
