基本解释

Variations in Earth’s magnetic field cause them to spin in different ways, each of which leaves the compass in a slightly different chemical state.
地球磁场不同的变化会造成它们不同的自旋方式，每种方式都会让罗盘的化学状态表现出细微的差异。
Hint: It is recommended that teams design their robots to cope with variations in lighting and magnetic conditions, as these vary from venue to venue.
提示：鉴于各个场地的条件不同，建议各队设计好自己的机器人使其能够适应各种照明和磁场情况。
The gravity and magnetic inversion has multitudinous variations. The common binary code mode and the search mode of genetic algorithm are not suitable to it.
重磁反演常具有众多变量，通常的遗传算法编码方式和搜索模式不能适用。
