等离子层,或内磁层是地球的磁层中包含低能量(冷)等离子的区域,它的位置在电离层之上,等离子层外面的边界被称为等离子层顶,在定义上该处的等离子密度已经降低了一个数量级。
此类在宇宙某一地区内形成的“哨声波”位于等离子层的正上方,这是地球的保护性磁泡,充满了等离子,或者说是荷电气体。
Such "chorus waves" form in a region of space that lies just above the plasmasphere, a section of Earth's protective magnetic bubble filled with plasma, or electrically charged gas.
由于等离子层中等离子的高浓度会阻止哨声波与粒子之间相互影响的有效性,故通常此类的电子加速是很难或几乎是不可能实现的。
Normally, such electron acceleration is difficult or impossible because the plasmasphere's high plasma density prevents the chorus waves from efficiently interacting with particles.
现在,研究人员还不清楚色球层的等离子气体为何能达到如此高的速度,也不知道为什么到达日冕后会有如此高的温度。
The researchers do not yet know what launches the chromospheric plasma at such high speeds nor what heats it to the extreme temperatures it reaches in the corona.
