资源简介:
The Earth magnetic field (Fig.1): BE – total magnetic flux density, BEx – x component of the Earth magnetic flux density, BEy = 0 y component of the Earth magnetic flux density, BEz – z component of the Earth magnetic flux density, I – the inclination of the Earth magnetic field.
The symmetrical prolate ellipsoid (Fig.2): L – length of the ellipsoid, a – radius of the ellipsoid, e – unidimensional coefficient, q - vertical angle, j - horizontal angle.
For each scenario there are the following files:
Ind_Bx_[BE]_[I]_[z]_[q]_[j]_[a]_[e]_[mr] Bx – component of the ellipsoid magnetic flux density [nT]
Ind_By_[BE]_[I]_[z]_[q]_[j]_[a]_[e]_[mr] By – component of the ellipsoid magnetic flux density [nT]
Ind_Bz_[BE]_[I]_[z]_[q]_[j]_[a]_[e]_[mr] Bz – component of the ellipsoid magnetic flux density [nT]
Ind_x_[BE]_[I]_[z]_[q]_[j]_[a]_[e]_[mr] x coordinate [m]
Ind_y_[BE]_[I]_[z]_[q]_[j]_[a]_[e]_[mr] y coordinate [m]
were:
BE [mT], I [deg], z [m], q [deg], j [deg], mr – relative magnetic permeability
Ind – induced magnetization of the ellipsoid
For the following parameters: Be = 50 mT, I = 70 deg, z = 100 m, q = 80 deg, j = 45 deg, a =4 m, e = 8, mr = 100
The names files are:
Ind_Bx_50_70_100_80_45_4_8_100 Bx – component of the ellipsoid magnetic flux density [nT]
Ind_By_50_70_100_80_45_4_8_100 By – component of the ellipsoid magnetic flux density [nT]
Ind_Bz_50_70_100_80_45_4_8_100 Bz – component of the ellipsoid magnetic flux density [nT]
Ind_x_50_70_100_80_45_4_8_100 x coordinate [m]
Ind_y_50_70_100_80_45_4_8_100 y coordinate [m]
地球磁场(图1):BE为总磁通密度(total magnetic flux density),BEx为地球磁通密度的x分量,BEy=0为地球磁通密度的y分量,BEz为地球磁通密度的z分量,I为地球磁场倾角。
对称长旋转椭球体(图2):L为椭球体长度,a为椭球体半径,e为一维系数,q为垂直角,j为水平角。
针对每个场景,均包含如下文件:
Ind_Bx_[BE]_[I]_[z]_[q]_[j]_[a]_[e]_[mr]:Bx为椭球体磁通密度的x分量,单位为纳特斯拉(nT)
Ind_By_[BE]_[I]_[z]_[q]_[j]_[a]_[e]_[mr]:By为椭球体磁通密度的y分量,单位为纳特斯拉(nT)
Ind_Bz_[BE]_[I]_[z]_[q]_[j]_[a]_[e]_[mr]:Bz为椭球体磁通密度的z分量,单位为纳特斯拉(nT)
Ind_x_[BE]_[I]_[z]_[q]_[j]_[a]_[e]_[mr]:x坐标,单位为米(m)
Ind_y_[BE]_[I]_[z]_[q]_[j]_[a]_[e]_[mr]:y坐标,单位为米(m)
其中各参数的含义与单位如下:
BE单位为毫特斯拉(mT),I单位为度(deg),z单位为米(m),q单位为度(deg),j单位为度(deg),mr为相对磁导率(relative magnetic permeability);Ind指代椭球体的感应磁化强度(induced magnetization)。
针对如下参数组合:BE=50 mT,I=70 deg,z=100 m,q=80 deg,j=45 deg,a=4 m,e=8,mr=100
此时对应的文件名为:
Ind_Bx_50_70_100_80_45_4_8_100:Bx为椭球体磁通密度的x分量,单位为纳特斯拉(nT)
Ind_By_50_70_100_80_45_4_8_100:By为椭球体磁通密度的y分量,单位为纳特斯拉(nT)
Ind_Bz_50_70_100_80_45_4_8_100:Bz为椭球体磁通密度的z分量,单位为纳特斯拉(nT)
Ind_x_50_70_100_80_45_4_8_100:x坐标,单位为米(m)
Ind_y_50_70_100_80_45_4_8_100:y坐标,单位为米(m)
