Umgangatho we-API umisela ukuba imiphezulu yangaphakathi nangaphandle yepetroleum engeniswe ngaphandle kunye nesuka ngaphandle.iibhokisi akufunekanga isongwe, yohlulwe, iqhekezwe okanye ikrwelwe, kwaye ezi ziphene kufuneka zisuswe ngokupheleleyo.Isingxobo sepetroleum kufuneka sigqunywe ngokupheleleyo ukuze kubonwe ubukhulu bodonga oluzenzekelayo.Okwangoku, kukho indlela yokulinganisa engathanga ngqo yobunzima bodonga olusekwe kumgaqo wokuvuza kwemagnethi.Akuyona indlela yokulinganisa ngokuthe ngqo ukutyeba kwodonga, kodwa indlela yokulinganisa ngokungathanga ngqo ubuninzi bodonga ngokulinganisa ulwazi lwemagnethi yokutshintsha okubangelwa kukuguquguquka kodonga.

Ke ngoko, amandla omhlaba wamagnetic anempembelelo enkulu ekuchanekeni nasekusonjululweni kokubonwa kobukhulu bodonga, kwaye ayifanelekanga ukufunyanwa ngokuzenzekelayo kwi-intanethi.Uyilo kunye nokukhethwa kweprobe kubalulekile kubunzima be-oyile ye-oyile.I-beam yesandi ekhutshwe yi-crystal piece ye-probe ngokubanzi inomlinganiselo othile kwaye iyanda ngokunyuka komgama.Ukukhetha i-acoustic beam ukugxila ekuhlaleni nge-acoustic lens ukwandisa amandla.
