1 Gavy Feld and Eleomane Feld Fne Geomeal Feld Theoy o Mae Moon Pa Two Xao Janha Naal ene Fondaon Reseah Gop, hanha Jaoon Unvesy hanha, P.R.C Absa: Gavy eld heoy and eleomane eld heoy ae well esablshed and onmed by epemens. The hwazshld me and Ke Me o Ensen eld eqaon shows ha he spaal deenal o me ae s he avy eld. Fo pe me dsplaemen eld, when s spaal deenals ae ommave, onsevave elds an be esablshed. When s spaal deenals ae non-ommave, Mawell eleomane eld eqaons an be esablshed. When he ona-ovaan s eqed o he non-ommave eld, boh Loenz ae and Colomb ae ae deved n hs eseah. The pape shows ha he lh s a speal mae n ha he addon o s Newonan mass and s Colomb ele hae s zeo. In a, hs onlson s e o he eleomane wave n vam. Fo he onsevave eld, he eseah shows ha one he mass densy and he Colom hae dendy ae ven, he mao spaeme eae s ompleely deemned. Boh o hem ae nsn eaes o mao mae n osm bakond. Howeve, o he osm aes old evens, he spaal vae may be anno be noed. On hs sense, he oldes avy eld has he laes vae o spae. Ths pon s vey nns o asonomy maes. Key Wods: eneal elavy, eleomane eld, avy eld, moon ansomaon. Inodon In he pape Ineal ysem and peal Relavy [], he symme mae moon ansomaon s dsssed. Fo Newonan mae moon, he vam s aken as a speal mae wh one nns physal paamee-lh speed. Fo any mae, an be dened wh o-movn oodnaos wh loal vayn eomey. The loal vayn eomey epesens he moon o mae n onsdeaon. The moon eqaon o mae s deemned by osm envonmen whee he mae esn, whee wo nns physal paamees ae noded o dene mae as,. When he me aden o me dsplaemen s oed o be zeo, he Newon s mehanal eqaon s oen. I shows ha he Newon s mass s deemned by he shea eae o spae-me onnm. The Newon s mass s epessed as ρ /. When he mae has no mao spaal moon, sh as avy eld o eleon eld, he me dsplaemen eld s noded o desbe he mae moon. One nds ha avy eld, eleo-mane eld, and qanm eld ae me aden eld. They ae elaed wh Newon s mehans n nns sense. When hee s no eleal hae qany, he avy mass and he neal mass n Newon s mehans ae he same. The mae has hee ypal esn oms: aveln wave, loalzed hamon vban

In hs pa, pe me dsplaemen eld wll be dsssed. In hs ase he moon ansomaon s non-symme. The eseah shows ha he eleomane eld an be dened by he pe me dsplaemen eld, he Mawell eqaons ae deved n hs pa. Fsly, he bas eqaons ae evewed smply. The mae moon n o-dmensonal spaeme onnm s dened by: Tha s he nal bas veos and en bas veos mee ansomaon eqaon: F The mae moon ansomaon enso F s deemned by eqaon: F δ whee, epesens ovaan devave wh espe o oodnao, δ s an n enso. The dsplaemen eld s also dened n he nal o-dmensonal o-movn oodnao sysem.theeoe, he mae moon s epessed by dsplaemen eld meased n sandad physal measn sysem. Is hee dmenssonal ase has been sded by Chen Zhda [-]. Geneally, he mae moon ansomaon enso s non-ommave. Is ovaan nde and ona-vaan nde ae dened espes wh o he nal o-dmensonal o-movn oodnao sysem. The aon o mae moon s dened as: Aon W F d d d d whee, W s a eneal non. The leas aon pnple [-8] ves he eld moon eqaons as: σ 5 whee, k l l σ C F F 6 l k k C k l W 7 k F F l

In hs sense, he nal mae an be eneally dened by sele he nal o-movn oodnao sysem o make: F δ On hs sense, he eeene mae s aken o dene he spaeme onnm whee he mae nde dssson s movn. The pnple o physal laws ovaan nvaane eqes he eneal eeene mae 9 moon be oodnao ndependen. To mee hese eqemens, he enso k C l ms be soop enso. Theeoe, one has: k C l δ δ δ δ k l l k whee, and ae he nns eae o mae een o eeene mae. Fo Newon mehans, he eeene mae s vam o ehe. Fo he soop enso n me om please ee [9]. In sandad physal heoy, he med om s esed. Howeve, he eseah shows ha he me om s neessay o show he non-ommave eae o mae moon ansomaon enso. Ths op shold ea n e ahe a pesen. Fo smples Newon moon, he elaed physal om o deomaon enso and sess enso ae: F δ The neal mass densy s dened as: σ ρ I nepes he as he nns neal eney o mae. The symme moon ansomaon n he om:
