Geographic Distribution of Reference Value of Diffusion Capacity for Carbon Monoxide of Lung Based on Artificial Neural Networks 基于人工神经网络的肺一氧化碳弥散量参考值的地理分布
In addition, the transverse angular rate can be decomposed into the yaw angular rate and pitch angular rate with the geographic coordinates of reference. 此外,配合地理坐标基准,可以将横向角速度分解为偏航角速度和俯仰角速度。
GIS supports the collection, storage and display of geographic space data, and provides information inquiry and analysis by relating the geographic space data with reference data. GIS支持地理空间数据的采集、存储和显示,并能将地理空间数据与相关参考数据关联以提供信息查询与分析。
By making use of the horizontal components of the earth rotation rate sensed by FOG at two directions with a phase difference of 180o, the intersecting angle between the geographic north and the reference axis of the FOG can be calculated accurately. 二位置寻北方案利用光纤陀螺对相差180°的两个方向上的地球自转角速率水平分量的敏感,精确地解算出地理真北方向与陀螺轴向的夹角。
Correlation Analysis on Geographic Factors and the Normal Reference Value of Red Blood Cell Count of Middleaged Women 中年女性红细胞计数正常参考值与地理因素的相关分析
