The Influence of Detecting Accuracy on the Coating Method Wind Field Detection of Membrane Surface Characteristics

提高四分区镀膜法中的膜面精度对光谱信息的提取起到关键性的作用。从四分区镀膜法的基本原理着手,对限制膜面倾角对风速和温度的测量精度进行调整和完善。膜面平整度的各种误差对测量结果有着直接的影响,直接关系到测量结果的精度。现有的风速和温度的测量精度对膜面平整度进行了误差限制,膜面上的点凹陷也对测量结果有明显的影响。通过特定的温度范围得出膜面倾斜角度的限制范围。误差范围的限定为四分区镀膜法风场探测的发展起到了关键性的作用。

Improving division of membrane method with four coating surface precision is a spectrum of the key role to the extraction of information. From the four division coating method to the basic principle and limit the membrane surface to dip angle measurement accuracy of the wind speed and temperature adjust and perfect. Membrane surface flatness of measurement has a direct impact to results of error, it can directly relates to the accuracy of the results. The existing wind speed and temperature measurement precision on the membrane surface roughness the error limit, membrane surface depression also point on the measurement results have apparent effect. It is concluded that the membrane surface angle limits by a specific temperature range. Error range of limited to four division coating method of detection of wind field development plays an important role.
