The Chinese also launched weather balloons near their theodolites to measure atmospheric temperature and pressure changes to better estimate refraction errors.
中国还在经纬仪附近发射了气象气球来测量大气温度和压力变化，以更好地估计折射误差。
One source of error is refraction, the bending of light beams as they pass through air layers of different temperature and pressure.
误差的一个来源是折射，即光束通过不同温度和压力的空气层时发生的弯曲现象。
According to the displacement of the fringe and the relation between temperature and index of refraction, a two-dimensional temperature profile is obtained.
根据条纹弯曲偏移量，由折射率与温度的关系，画出空气温度的二维分布图。
