黑子經常成雙成對出現，每對皆由極性相反的黑子組成，若一個為磁北，另一個必為磁南，由此我們估計每對黑子皆由磁力線所連系，強大的磁場牽制著光球層上的氣體，並阻止了下層較熾熱的氣體上升至黑子范圍，結果黑子比太陽表面其他地方溫度較低。 -

But the magic of a conformal mapping is that the device is guaranteed to operate in identical fashion to the circular version, just with the geometry of all the critical elements ( semiconductor, metal, field lines and current flows ) transformed by the mapping
不過保角映射的神奇之處在於，它能確保這個裝置會以和其圓形版本完全相同的方式運作，所有的關鍵元素（半導體、金屬、場線與電流）都會隨著保角映射被轉換過去。 -

After the discussion of the numerical simulation method based on the fdtd method and the pml technique, the motions of the charges and the electrical field lines were first employed to describe the radiation procedures of the pulse electromagnetic waves. then the causes of how the charges are accelerated and how the motion status of the charges are maintained were further studied from the angle of interaction of charge and field. after these analyses, it was pointed out that the pulse radiation is due to the suddenly occurred time - varying electrical field ( displacement current ) in the open space. this view was further evidenced by two examples : one is the partly resistance loaded antenna, the other is the partly curved antenna. the radiation procedures of the pulse electromagnetic waves of many different situations were simulated throughout this paper with the contours and waveforms of electric field given. these figures are very helpful to the understanding of the radiation mechanism of the pulse electromagnetic waves
在討論了基於時域有限差分法和完全匹配層技術的數值模擬方法之後，首先從運動電荷和電力線的角度直觀地描述了脈沖電磁波的輻射過程，然後進一步從場與電荷相互作用的角度分析了天線上電荷是如何被加速以及如何維持其運動狀態的，指出了開放空間中突然出現的時變電場（位移電流）是脈沖電磁波輻射的根本原因.文中還對局部電阻加載的天線和局部彎曲的天線進行了研究，以進一步說明上述觀點.對多種情況下的脈沖輻射過程進行了數值模擬，並給出了電場的等高線和空間波形圖，這些圖形對理解脈沖電磁波的輻射機理非常有益 -

摘要趨磁細菌菌體內含有磁小體，能夠沿地球磁力線方向定位、運動，趨磁細菌和磁小體的研究具有重要的理論意義和應用價值。 -
Under certain conditions, however, the imf ' s field lines can tilt out of the equatorial plane of the sun, taking on a northward or southward component
然而在特定情況下， imf磁力線會偏斜出太陽的赤道面，產生南北向的分量。 -
The variation must in a swimming pool will soon diffuse throughout the pool, a concentration of magnetic field lines diffuses throughout the planet ' s outer core
與游泳池中一滴有色的染料在池中迅速擴散的方式一樣，一個濃縮的地磁場曲線的擴散遍布地球的外核。 -
So the rare field reversals are most likely caused by larger changes in the flow in the outer core, or in the way in which the field lines are wound into the flow by diffusion
這樣，不經常發生的磁場倒轉，很可能是由外核流體或磁場曲線通過擴散宛然進人流體方式發生較大的變化而引起的。 -
Consequently, heat conduction along the magnetic field lines on the surface of a magnetar is far more efficient than the heat conduction perpendicular to the magnetic field lines. this may lead to a profound effect on the thermal evolution as well as the shape of the x - ray pulse of a magnetar
結果，沿著磁星表面磁線的傳熱作用較與磁線垂直的傳熱作用為佳，這現象對磁星的熱演化和x射線脈沖的形狀有著很大的作用。 -
As the wind carries this interplanetary magnetic field ( imf ) away from the sun, the field lines typically stretch out so that they are directed radially ( pointing toward or away from the sun )
這種行星際磁場（ imf ）的磁力線基本上都是往外拉的，也就是徑向的（即不是指向，就是背向太陽的方向） 。 -
The key turns out to be a sudden rearrangement of magnetic field lines, a phenomenon called reconnection
