  1. In order to verify the simulation field, the ultrasonic wave field radiating by a planar transducer was measured by small ball. by comparing the simulation field with the measured field, it is found that mgb is accurate in the far - field and most near - field region

    為了驗證聲場模擬的可靠性，利用小球法測量了直探頭的水中輻射聲場，將試驗聲場和模擬聲場比較，發現多元高斯聲束模型在遠場區和大部分近場區都是有效的。
  2. Far below the southern tip of africa they found a small region where the magnetic field lines point peculiarly toward the center of the earth instead of toward the surface, as do the dominant lines in that region

    他們發現，在非洲南端的地表深處，有一小塊區域，那兒的磁場磁力線罕見地指向地心，而不是如該區域的主磁場磁力線一般地指向地表。
  3. In order to improve the efficiency, the fast far field approximation ( faffa ) and a novel local iteration technique based on dynamic coupling region controlling are applied to the original fipwa

    為進一步提高求解效率，將快速遠場近似與之混合;採用一種新型的動態控制耦合半徑的局部迭代技術。
  4. Awg possesses an essential function of coherence system - " composing frequency and generating image ". therefore as far as spatial frequency field is concerned, awg is an optical integration of coherent system : two slab waveguides similar to two fourier lenses of one dimension and twice fourier transform of optical signals are realized. here the arrayed waveguide region is frequency spectrum region

    Awg具有相干系統的「分頻成譜、合頻成像」這一本質功能，因此若從空間頻域的角度來看， awg就是一個相干系統的光學集成：兩個平板波導類似兩個一維傅里葉透鏡，實現光信號的兩次傅里葉變換；而陣列波導區即為頻譜區。
  5. So it is necessary to reflect the inner reality physical field ' s numerical number analogy method to analysis and improve the magnetic field and the computing accuracy of the cable ' s eddy - current detection.
