 ### description
 #### Syntax
 
-`DOUBLE ST_Distance_Sphere(DOUBLE x_lng, DOUBLE x_lat, DOUBLE y_lng, DOUBLE 
x_lat)`
+`DOUBLE ST_Distance_Sphere(DOUBLE x_lng, DOUBLE x_lat, DOUBLE y_lng, DOUBLE 
y_lat)`
 
 
 计算地球两点之间的球面距离,单位为 米。传入的参数分别为X点的经度,X点的纬度,Y点的经度,Y点的纬度。
 
+x_lng 和 y_lng 都是经度数据,合理的取值范围是 [-180, 180]。
+x_lat 和 y_lat 都是维度数据,合理的取值范围是 [-90, 90]。
