A first resonance frequency is determined by the length of the rectangular microstrip antenna.

第一谐振频率由矩形微带天线的长度所决定。

An L-shaped band elimination filter on the T-shaped joint part is also used for restricting the resonance of the frequency multiplication of the first resonance frequency.

位于T形接合部上的L形带阻滤波器亦用来抑制第一谐振频率的倍频的谐振。

IBM physicists built the first microscope based on that approach, dubbed magnetic resonance force microscopy (MRFM), in 1993.

基于这个原理，IBM的物理学家们于1993年研制出了世界上第一台磁共振力显微镜(MRFM)。

In 2000, Knutson published the first paper using magnetic resonance imaging to photograph what goes on in the brain as people deal with money.

It's based on his work using functional magnetic resonance imaging brain scans that first demonstrated that, when people are asked to imagine themselves in retirement, the parts of their brains that usually "light up" when they think about themselves don't light up at all.

Researchers at 11 institutions are mapping the largest conduits among brain regions by combining four imaging techniques, including a new method called diffusion magnetic-resonance imaging that allows researchers for the first time to accurately map the white matter of nerve fibers.
