The basic idea is unchanged: The card is a token, a unique number encoded in a magnetic stripe.

基本的理念是一样的：卡片是一种权标，一种编码在磁性条码上的独一无二的号码。

As the field wanes, the number of sunspots falls to a trough or minimum, at which point the sun's magnetic field reverses direction and starts to regain its strength.

随着磁场减弱，太阳黑子的数量会减少到最小值或者说最低点(波谷)，然后太阳的磁场就会反方向运动，开始重新变强。

And this spin magnetic quantum number we abbreviate as m sub s, so that's to differentiate from m sub l.

这个自旋磁量子数我们把它简写成m下标s，以和m小标l有所区分。

And when you solved the relativistic form of the Schrodinger equation, what you end up with is that you can have two possible values for the magnetic spin quantum number.

当你们解相对论形式的,薛定谔方程，你们最后会得到两个,可能的自旋磁量子数的值。

No, we can't. Because if l equals 1, we can not have m sub l equal negative 2, right, because the magnetic quantum number only goes from negative l to positive l here.

不行，因为如果ｌ等于１,ｍｌ的值不可能等于－２，对吧，因为磁量子数的值,这时只能从－１到１

We use more than twice the number of MRI (magnetic response imaging) tests as the OECD median.

FORBES: Who Causes Half of Healthcare Costs?

When Cluster II passes through these so-called polar cusps, instruments on board each of its satellites will measure the magnetic field, electrical current and number of charged particles within the tetrahedron.

ECONOMIST: Birds of a feather

The 16-digit account number stored in your card's magnetic stripe zooms across a leased phone line to the merchant's bank, zips under the Pacific to Visa's data center outside Tokyo and rides the Visa network to the data center of your issuing bank in Delaware.
