from astropy import constants as const # 计算地球到太阳的平均距离 distance_to_sun = const.auprint(f"地球到太阳的平均距离:{distance_to_sun} 米") 优缺点: 优点: 专业性: 专为天文学领域设计,提供广泛的天文学工具和数据结构。 功能丰富: 包含常用的天文学功能,方便处理和分析天文数据。 社区支持:...
然后就出现了即将要讲解的 Python 模块——astropy。...01 上知天文我们首先来看一下模块 astropy,astropy 是一个社区的针对天文学的 Python 库。...astropy 包包含关键的功能和用 Python 进行天文学和天体物理学研究的工具。...数据结构和转换 常量(astropy.constants) astropy.constants 包含大量的在天文学...
要引入物理常数: from astropy.constants import G #万有引力常数 单位的变化,比如计算万有引力的时候,单位很复杂,要用N,即牛顿表示: F.to(u.N) 那么不同量纲之间是否能转换呢,原则上是不可以的,但某些情况下也能做到,比如: (450. * u.nm).to(u.GHz, equivalencies=u.spectral()) #纳米转化为GHz q...
scipy.constants.physical_constants返回许多特定物理常数的元组(值、单位、不确定性)。单位以字符串的形式给出。跟踪你的单位在科学计算中是非常重要的,但是,对于我来说,我还没有找到任何将这些字符串解析成可以被跟踪的东西的工具。如果没有这一点,就无法在不同的值相互相加、相减等之后简化合并的单位。我知道我可...
