Lapaʻau ultrasound transducer probe L38 hale
Ka manawa hoʻouna: I ka manawa wikiwiki loa, e hoʻouna mākou i nā waiwai i ka lā hoʻokahi ma hope o kou hōʻoia ʻana i kāu koi.Inā nui ka noi a he mau koi kūikawā paha, e hoʻoholoʻia ma muli o ke kūlana maoli.
L38 ka nui o ka hale:
Nā hōʻailona hana o nā mea kani ultrasonic:
ʻO ke kumu o ka ʻimi ultrasonic ʻo ka piezoelectric chip.Hiki ke hana ʻia nā wafers me nā ʻano mea like ʻole.ʻOkoʻa ka nui o ka chip, e like me ke anawaena a me ka mānoanoa, no laila ʻokoʻa ka hana o kēlā me kēia probe, a pono mākou e hoʻomaopopo i kāna hana ma mua o ka hoʻohana ʻana.ʻO nā hōʻailona hana nui o nā mea kani ultrasonic nā:
1.ʻO ke alapine hana - ʻo ia ke alapine resonant o ka chip piezoelectric.Ke like ka alapine o ka volta AC i nā wēlau ʻelua me ke alapine resonant o ka chip, ʻoi aku ka nui o ka ikehu puka a ʻoi aku ka kiʻekiʻe o ka naʻau.
2.ʻO ka wela hana - No ka mea, ʻoi aku ka kiʻekiʻe o ka wahi Curie o nā mea piezoelectric, ʻoi aku ka nui o ka diagnostic ultrasonic probes e hoʻohana i ka mana liʻiliʻi, haʻahaʻa haʻahaʻa ka mahana hana a hiki ke hana no ka manawa lōʻihi me ka hemahema.He kiʻekiʻe ka wela o nā ʻimi noiʻi ultrasound lapaʻau a koi aku i nā mea hoʻoheheʻe ʻokoʻa.
3.ʻIke - pili nui i ka wafer hana ponoʻī.Inā nui ka electromechanical coupling coefficient, kiʻekiʻe ka ʻike;akā, haʻahaʻa ka naʻau.
