LMEC-16 Sesebelisoa sa Tekanyo ea Velocity ea Sound le Ultrasonic Ranging
Lebelo la ho hasanya leqhubu la molumo ke palo ea bohlokoa ea 'mele. Ka mahlaseli a sekhahla, boemo, mokelikeli oa velocity, lisebelisoa tsa elastic modulus, mocheso oa khase hanghang phetoho ea phetoho, e tla kenyelletsa lebelo la molumo bongata ba 'mele. Phetiso le kamohelo ea ultrasound hape ke e 'ngoe ea mekhoa ea bohlokoa ea ho loants'a bosholu, ho lekola le tlhahlobo ea bongaka. Sesebelisoa sena se ka lekanya lebelo la phatlalatso ea molumo moeeng le bolelele ba leqhubu la molumo moeeng, mme sa eketsa liteko tsa liteko tsa mahlaseli a maqhubu, hore baithuti ba tsebe ho tseba melao-motheo le mekhoa ea liteko ea leqhubu la leqhubu.
Liteko
1. Lekanya lebelo la leqhubu la molumo le jalang moeeng ka mokhoa oa tšitiso ea molumo.
2. Lekanya lebelo la keketseho ea leqhubu la molumo moeeng ka mokhoa oa papiso ea mokhahlelo.
3. Lekanya lebelo la leqhubu la molumo le jalang moeeng ka mokhoa oa phapang ea nako.
4. Lekanya sebaka sa boto ea mokoallo ka mokhoa oa ho bonahatsa.
