Matekiniki ekuyera simba regiravhiti muGeophysics
Kuyerwa kwesimba regiravhiti kunoita basa guru muzvikamu zvakasiyana-siyana zve geophysical. Matekiniki aya anoshandiswa kunzwisisa chimiro cheNyika uye mashandiro ayo, pamwe nekuwana ruzivo nezvemukati meNyika nezviwanikwa zvayo. Chinyorwa chino chichaongorora matekiniki akasiyana-siyana ekuyera simba regiravhiti anoshandiswa mu geophysics uye mashandisirwo azvo mukutsvaga nekutsvaga.
Nhanganyaya yekuyera simba regiravhiti
Simba rinokwevera pasi (gravity) ndiro simba rinokwezva vanhu vaviri. Pasi, simba rinokwevera pasi rinopesvedzera kufamba kwematombo, makungwa, uye mhepo. Kusiyana kwesimba rinokwevera pasi kubva panzvimbo imwe kuenda kune imwe pamusoro pePasi kunogona kupa ruzivo rwakakosha nezvekupararira kwesimba mukati mePasi.
Mutemo waNewton weKukwevera Zvinhu Pasi
Hwaro hwekuyera simba rinokwevera pasi iMutemo waNewton weGravitation Yese, uyo unoti simba rinokwevera pasi riri pakati pemasasi maviri \(m_1\) uye \(m_2\) rinoenderana zvakananga nechibereko chemasasi uye rinoenderana nechikamu chedaro riri pakati pawo. Iyi equation inopiwa na:
\[ F = G \frac{m_1 m_2}{r^2} \]
apo \(G\) iri simba regiravhiti risingaperi repasi rose.
Kuwanikwa kweData reGravity
Ruzivo rwesimba rinokwevera pasi rinogadzirwa nenzira dzakasiyana-siyana dzekuyera, kusanganisira ongororo dzemumunda, masateliti, uye mamodheru esimba rinokwevera pasi. Ruzivo urwu runogona kubatsira masayendisiti kupindura mibvunzo yakasiyana-siyana nezvemaumbirwo emukati meNyika, zvakaita sekuvapo kwenzvimbo dzakaita sedimentary, kusagadzikana kwematombo, nezvimwewo.
Maitiro Ekuyera Simba Rekukwevera Simba
Chaizvoizvo, kune mhando mbiri huru dzenzira dzinoshandiswa pakuongorora simba remagetsi: nzira dzakananga uye nzira dzisina kunanga. Heano mamwe emaitiro anonyanya kushandiswa:
1. Chiyero cheGravimeter yeNyika
Gravimeter chishandiso chinoshandiswa kuyera kukurumidza kwegiravhiti panzvimbo penyika. Gravimeter yepasi, inozivikanwawo segravimeter chaiyo, chishandiso chinonyatsonzwa musiyano mudiki kwazvo wegiravhiti.
Prinsip Kerja
Magravimeter epasi anowanzo shandisa chitubu kana pendulum se sensor. Kana mudziyo wacho waiswa pamusoro pePasi, simba rinokwevera pasi rinodhonza chinhu chekuyedza, uye simba iri rinoyerwa nemazvo uchishandisa sensor yakabatanidzwa.
Kushanda
Magravimeter anoshandiswa zvakanyanya mukutsvaga mafuta negasi, kuchera zvicherwa, uye kuchinja kwemapu muchimiro chepasi nekuda kwekushanda kwetectonic.
2. Gravimeter yemvura yemugungwa
Magravimeter emugungwa anoshandiswa kuyera kusagadzikana kwegiravhiti mugungwa. Anowanzoiswa pazvikepe kana mapuratifomu emugungwa uye anobvumira kuyerwa kwegiravhiti munzvimbo dzisingasvikike nemagravimeter emugungwa.
Prinsip Kerja
Chinoyera mvura yemugungwa chine nzira yekusimbisa ngarava, zvichiita kuti ikwanise kuyera zvinhu nemazvo.
Kushanda
Zviyero zvemvura yemugungwa zvinowanzo shandiswa mukuongorora mafambiro egungwa, kuyera nzvimbo dzakaparadzwa nematombo kana kutsvaga zviwanikwa zvechisikigo pasi pegungwa.
3. Setiraiti Yegiravhiti
Kuyerwa kwesimba regiravhiti kunogonawo kuitwa uchishandisa masatelaiti. Muenzaniso unozivikanwa zvikuru ibasa reGRACE (Gravity Recovery and Climate Experiment), iro rakashandisa masatelaiti maviri kuyera musiyano wesimba regiravhiti pamusoro pePasi.
Prinsip Kerja
Masatellite maviri eGRACE akaburitswa mumatanho akasiyana zvishoma asi ari pedyo, achitarisa shanduko dziri pakati pawo. Shanduko idzi dzinokonzerwa nekusiyana kwegiravhiti pasi penzira dzawo dzekubhururuka, izvo zvinotsanangurwa kuita data regiravhiti.
Kushanda
Data kubva kumasatellite akadai seGRACE inobatsira zvikuru pakutarisa shanduko yemamiriro ekunze, chando chepolar, uye kusiyana kwemamiriro emvura pasi rose.
Kuongororwa kweData reGravitational
Kuunganidza data rekukwevera pasi inhanho yekutanga chete. Data rakaunganidzwa rinofanira kugadziriswa uye kuongororwa kuti riwane ruzivo runobatsira.
Kugadziriswa kweData
Ruzivo rwegiravhiti runoda kugadziriswa kwakasiyana-siyana kuti kubviswe migumisiro isiri yejeogiravhiti. Zvimwe zvinogadziriswa zvakajairika zvinosanganisira:
- Kugadziriswa kweTidal: Kunobvisa mhedzisiro yemafungu egungwa uye mhepo inoyerera padata regiravhiti.
- Kugadzirisa Bouguer: Inogadzirisa data regiravhiti kuti rienderane nekukwirira kwekuyera pamusoro pegungwa.
- Kugadziriswa kweLati neLongitudinal: Nekufunga nezvekuchinja kwegiravhiti pamatanho akasiyana-siyana uye marefu.
Kugadziriswa kwedata
Mushure mekugadziriswa, data regiravhiti rinogadziriswa kuburikidza nemaalgorithms akasiyana-siyana uye nzira dzekududzira. Izvi zvinosanganisira matekiniki akadai se:
– Frequency Filter: Kuparadzanisa mamiriro asina kunaka emunzvimbo kubva kumatunhu.
- Kuongorora Magadzirirwo Ezvinhu: Kuona zvinhu zvinodzivirira magadzirirwo ezvinhu mudata.
– Kugadzira Mepu ye3D: Kugadzira modhi ine mativi matatu yekupararira kwehukuru pasi penyika.
Mashandisirwo muGeophysics
Kuyerwa kwesimba regiravhiti kunoita basa guru muzvikamu zvakasiyana zve geophysics. Mamwe emashandisirwo azvo makuru anosanganisira:
Kuongorora Oiri neGasi
Kusarongeka kwesimba regiravhiti kunogona kuratidza kuvapo kwenzvimbo dzine mafuta negasi. Nzira dzekuongorora simba regiravhiti dzinowanzo shandiswa pakutanga kwekutsvaga kuti vaone nzvimbo dzakakosha.
Tsvagiridzo yeMaumbirwo Enyika
Ruzivo rwegiravhiti runobatsira vanoongorora zvepasi kuti vaongorore chimiro chemukati mePasi, zvakaita semiganhu yeplate yetectonic, kuvapo kwemakomo anoputika ari pasi pemvura, nezvimwe zvinhu zvepasi.
Kutarisa Kuchinja Kwemamiriro Ekunze
Kuchinja kwesimba regiravhiti kunogona kushandiswa kutarisa shanduko muhuwandu hwechando pamipendero uye kufungidzira shanduko muhuwandu hwemvura munzizi nemadziva.
Matambudziko uye Kugadzira Zvinhu Zvitsva
Kunyangwe paine kufambira mberi kukuru kwakaitwa muhunyanzvi hwekuyera simba regiravhiti, matambudziko achiripo. Semuenzaniso, kuyera simba regiravhiti munzvimbo dzakaoma kusvika (senge masango ane matombo kana nzvimbo dzine matombo) uye kugadzirisa data rakakura uye rakaoma kunzwisisa.
Zvisinei, kufambira mberi kwetekinoroji kwakadai sekushandiswa kwemadrone pakuyera simba remuchadenga pamwe nekuwedzera kwe resolution uye kururama kwemasetiraiti esimba remuchadenga zvinopa tariro yeramangwana rakajeka mu geophysics.
Mhedziso
Matekiniki ekuyera simba regiravhiti mu geophysics maturusi akakosha ekunzwisisa chimiro cheNyika uye mashandiro ayo. Kubva kumagravimeter epasi negungwa kusvika kumaseteraiti egiravhiti, nzira imwe neimwe ine zvayakanakira uye mashandiro ayo mukushandiswa kwakasiyana-siyana. Kunzwisisa zviri nani simba regiravhiti rePasi hakungobatsiri chete mukutsvaga zviwanikwa zvechisikigo asiwo kunopa ruzivo rwakakosha rwekutarisa nekuderedza shanduko yemamiriro ekunze. Sezvo tekinoroji ichifambira mberi, remangwana rekuyera simba regiravhiti mu geophysics rinotaridzika richivimbisa zvakanyanya.
