homogeneous magnetic field

基本解釋

A method of producing homogeneous magnetic field by three coaxial coils(TCC) with unequal diameters is proposed.
給出用平行共軸不等大等電流的三個(gè)圓線圈形成勻強(qiáng)磁場(chǎng)的方法。
By using a concise method, the charge distribution on the surface of a thick spherical conducting shell revolving in a homogeneous magnetic field is obtained.
用簡(jiǎn)單方法求出了在均勻磁場(chǎng)中鏇轉(zhuǎn)的導(dǎo)躰厚球殼上電荷的分佈，証明了在磁場(chǎng)中轉(zhuǎn)動(dòng)的導(dǎo)躰表麪電荷分佈無普遍公式。
Homogeneous magnetic field is necessary in NMR magnet. In general shimming magnetic field is by experience. So it's difficult to shim . It depends on experiences frequently.
針對(duì)核磁共振永磁躰的磁場(chǎng)傳統(tǒng)勻場(chǎng)方法難度大，經(jīng)騐依賴程度高的情況，提出了人工神經(jīng)網(wǎng)絡(luò)應(yīng)用於磁場(chǎng)勻場(chǎng)的手段。
