常見例句E-H field is equivalent to a magnetic Hertzian diplole.(4). 三、環(huán)形電流陣列之電磁場分布等效于一微小磁偶極。。Each segment of line current can be approximated as a Hertzian dipole if each segment is much smaller then a wave length. 因此任意線電流在三度空間之三維向量電磁場即可以赫芝電偶極完整之遠(yuǎn)場及近場近似合成之。On the base of Hertzian stress theory of elastic mechanics,a new kind of disk cam mechanism whose follower has concave circle arc bottom is developed. 根據(jù)彈性力學(xué)的赫茲應(yīng)力理論,提出了一種從動件結(jié)構(gòu)形狀為凹圓弧底的新型盤狀凸輪機(jī)構(gòu)。Hertzian pays attention to even the smallest detail.Pictured is the carriage roller system of the drafting board. 圖6:赫芝制圖儀的品質(zhì)精良,連小地方也不放過,圖為平行規(guī)尺和制圖板側(cè)以螺絲精密銜接。The radial cracks are caused by local bend, and the cone cracks are caused by Hertzian tensile stress. 由于石板的尺寸有限,錐形裂紋可以發(fā)展到石板背面,石板上被沖出小錐體;The pattern and/or image of electric and/or magnetic field of an electric Hertzian dipole in the near and far field. 赫芝電偶極在遠(yuǎn)近場區(qū)中之電場與磁場之場型及影像。 返回 Hertzian
