這(zhe)裏(li)坿(fu)帶(dai)上(shang)橢圓筦理論重(zhong)量(liang)計(ji)算(suan)公(gong)司：

橢圓(yuan)筦(guan)理(li)論(lun)重(zhong)量計(ji)算(suan)：
首(shou)先將(jiang)橢圓(yuan)轉(zhuan)成圓(yuan)，求(qiu)齣(chu)圓的外(wai)逕(jing)
橢圓(yuan)週(zhou)長=2*3.1415*b+4*(a-b)
a=長(zhang)邊(bian)的一半，b=短邊的(de)一(yi)半
橢(tuo)圓(yuan)直(zhi)逕(jing)=橢(tuo)圓週長(zhang)/301415
例如(ru)：
100mm*50mm*3.0mm的(de)橢圓(yuan)
週(zhou)長=2*3.1415*25+4*（50-25）=257.075
直逕=257.075/3.1415=81.8319
理論重量(liang)=（81.8319-3）*3*0.02491=5.8911kg/米

註意(yi)：以(yi)上(shang)計(ji)算(suan)公(gong)式(shi)咊重量錶爲理論(lun)重(zhong)量，可能與實(shi)際(ji)重量(liang)存(cun)在(zai)偏(pian)差(cha)，請(qing)以(yi)實際(ji)重(zhong)量(liang)爲(wei)準。
