已经发现地球磁场的偶极表示对于磁捕获粒子的研究具有不足的准确性。已经发现，由磁场的大小和积分不变量I组成的坐标系，可以适当地组织在不同地理位置所作的测量。本文表明，可以定义一个参数L = L（B，I），它保留了I的大部分理想性质，并具有沿沿着力线组织测量的附加性质。由于参数L是偶极场中物理距离（磁壳的赤道半径）的模拟，通常发现它比积分不变量I在概念上的困难要少。
Dipole representations of the earth's magnetic field have been found to have insufficient accuracy for the study of magnetically trapped particles. A coordinate system consisting of the magnitude of the magnetic fieldBand the integral invariantIhas been found to organize adequately measurements made at different geographic locations. The present paper shows that a parameterL= ƒ(B,I) can be defined that retains most of the desirable properties ofIand that has the additional property of organizing measurements along lines of force. Since the parameterLis the analog of a physical distance in a dipole field (the equatorial radius of a magnetic shell), it is usually found to present fewer conceptual difficulties than the integral invariantI.
