According to the direction of errorsensitivity, three-dimension errors are reduced to two-dimension ones.
根据误差敏感方向 ，将三维误差简化为二维平面误差。

Secondly, error modules of main braking were established and errors of the guidance law designed above were analyzed by errorsensitivity coefficient matrixes.
其次，建立了月球软着陆主制动段的误差模型，并运用误差敏感系数矩阵对所提出制导律的制导误差进行分析。

This channel coding based on source utilizes the property of compressed data which generated in order of importance, and improves the limitation to errorsensitivity.
