廈(sha)門君朗益電(dian)(dian)(dian)(dian)動(dong)(dong)車(che)(che)(che)有限公司以交通運輸為(wei)主，建立了完(wan)善的產品體系(xi)。主營：電(dian)(dian)(dian)(dian)動(dong)(dong)車(che)(che)(che)，電(dian)(dian)(dian)(dian)動(dong)(dong)旅游觀光車(che)(che)(che)，電(dian)(dian)(dian)(dian)動(dong)(dong)巡(xun)邏車(che)(che)(che)，電(dian)(dian)(dian)(dian)動(dong)(dong)環(huan)衛(wei)車(che)(che)(che)，電(dian)(dian)(dian)(dian)動(dong)(dong)消(xiao)防車(che)(che)(che)，電(dian)(dian)(dian)(dian)瓶(ping)車(che)(che)(che)租(zu)賃、保養維修等(deng)。

電(dian)(dian)壓(ya)(ya)可(ke)分為(wei)高(gao)電(dian)(dian)壓(ya)(ya)，低(di)(di)電(dian)(dian)壓(ya)(ya)和安全電(dian)(dian)壓(ya)(ya)。高(gao)低(di)(di)壓(ya)(ya)的(de)(de)(de)區別是(shi)：以電(dian)(dian)氣設(she)備(bei)的(de)(de)(de)對(dui)地的(de)(de)(de)電(dian)(dian)壓(ya)(ya)值為(wei)依據(ju)的(de)(de)(de)。對(dui)地電(dian)(dian)壓(ya)(ya)高(gao)于(yu)或等于(yu)1000伏(fu)的(de)(de)(de)為(wei)高(gao)壓(ya)(ya)。對(dui)地電(dian)(dian)壓(ya)(ya)小于(yu)1000伏(fu)的(de)(de)(de)為(wei)低(di)(di)壓(ya)(ya)。其中安全電(dian)(dian)壓(ya)(ya)指人體較(jiao)長時間接(jie)觸而(er)不(bu)致發生觸電(dian)(dian)危(wei)險的(de)(de)(de)電(dian)(dian)壓(ya)(ya)。

廈門君朗益(yi)電(dian)動車(che)有限公司(si)以交(jiao)通(tong)運輸(shu)為主，建立了完(wan)善的(de)產品體系。主營：電(dian)動車(che)，電(dian)動旅游觀光車(che)，電(dian)動巡邏車(che)，電(dian)動環衛(wei)車(che)，老爺車(che)，電(dian)動消防車(che)，電(dian)瓶車(che)租賃、保養維(wei)修(xiu)等。

電(dian)(dian)(dian)路(lu)(lu)或電(dian)(dian)(dian)路(lu)(lu)元件(jian)的功(gong)率(lv)(lv)定(ding)(ding)義為(wei)：【功(gong)率(lv)(lv)=電(dian)(dian)(dian)壓*電(dian)(dian)(dian)流（P=I*V）】。自然界里能(neng)(neng)量(liang)不會消滅，固(gu)有(you)一定(ding)(ding)律(lv)【能(neng)(neng)量(liang)守恒定(ding)(ding)律(lv)】。電(dian)(dian)(dian)路(lu)(lu)總(zong)功(gong)率(lv)(lv)=電(dian)(dian)(dian)路(lu)(lu)功(gong)率(lv)(lv)+各電(dian)(dian)(dian)路(lu)(lu)元件(jian)功(gong)率(lv)(lv)。例如：【電(dian)(dian)(dian)源（I*V）=電(dian)(dian)(dian)路(lu)(lu)（I*V）+ 各元件(jian)（I*V）】在(zai)電(dian)(dian)(dian)路(lu)(lu)中(zhong)的能(neng)(neng)量(liang)有(you)時會變為(wei)熱能(neng)(neng)或輻射能(neng)(neng)…等其(qi)他能(neng)(neng)量(liang)到空氣中(zhong)，老爺車(che)租賃(lin)，這就是電(dian)(dian)(dian)路(lu)(lu)或電(dian)(dian)(dian)路(lu)(lu)元件(jian)會發熱的原因

廈門君(jun)朗(lang)益電(dian)(dian)動車(che)(che)(che)(che)有限(xian)公司以交通運輸(shu)為主，建立了(le)完善(shan)的產品體系。主營(ying)：電(dian)(dian)動車(che)(che)(che)(che)，電(dian)(dian)動旅游觀光車(che)(che)(che)(che)，電(dian)(dian)動巡邏(luo)車(che)(che)(che)(che)，電(dian)(dian)動環衛車(che)(che)(che)(che)，電(dian)(dian)動消防車(che)(che)(che)(che)，老(lao)爺(ye)車(che)(che)(che)(che)租賃，電(dian)(dian)瓶(ping)車(che)(che)(che)(che)租賃、保養維修等(deng)。

對(dui)(dui)于一個具有n個結點和(he)b條(tiao)支(zhi)路(lu)(lu)的(de)(de)電(dian)(dian)路(lu)(lu)，假設各條(tiao)支(zhi)路(lu)(lu)電(dian)(dian)流(liu)和(he)支(zhi)路(lu)(lu)電(dian)(dian)壓(ya)取(qu)關(guan)聯參考方向，并令(ling)（i1，i2，···，ib）、（u1，u2，老爺(ye)車租(zu)賃，···，ub）分(fen)別(bie)為b條(tiao)支(zhi)路(lu)(lu)的(de)(de)電(dian)(dian)流(liu)和(he)電(dian)(dian)壓(ya)，則對(dui)(dui)于任(ren)何時(shi)間t，有i1*u1+i2*u2+···+ib*ub=0。在對(dui)(dui)偶電(dian)(dian)路(lu)(lu)中，某些元(yuan)素之間的(de)(de)關(guan)系（或方程）可(ke)以通(tong)過對(dui)(dui)偶元(yuan)素的(de)(de)互換而相互轉換。
