Anisotropy yog cov khoom qub tshaj plaws uas pom nyob rau hauv cov ntaub so ntswg musculoskeletal thiab tseem ceeb heev hauv kev txheeb xyuas cov qauv xws li cov leeg (Fig. 42.2, Video 42.1). Anisotropy tshwm sim thaum lub kaum sab xis ntawm lub nqaj ultrasound tsis nyob rau sab rau ntawm cov ntaub so ntswg raug kuaj.

Dab tsi ua rau anisotropy?

Yog vim li cas rau ntuj anisotropy yog qhov kev txiav txim ntawm cov khoom hauv cov muaju uas sib cais ntawm cov khoom uas nyob ib sab-thiab yog li ntawd cov cohesive rog ntawm lawv-nws txawv nyob rau hauv ntau cov lus qhia. Anisotropy yog tshwm sim los ntawm asymmetry thiab kev taw qhia tshwj xeeb ntawm cov molecules lawv tus kheej.

piv txwv ntawm anisotropy yog dab tsi?

anisotropic: Cov khoom ntawm cov khoom nyob ntawm qhov kev taw qhia; piv txwv li, wood. Hauv ib daim ntoo, koj tuaj yeem pom cov kab mus rau hauv ib qho kev coj; qhov kev taw qhia no yog hu ua "nrog cov nplej". Cov ntoo muaj zog nrog cov nplej ntau dua li "tiv thaiv cov nplej."

Dab tsi yog hauv anisotropy?

Anisotropy, hauv physics, qhov zoo ntawm cov khoom pov thawj nrog cov txiaj ntsig sib txawv thaum ntsuas raws axes hauv cov lus qhia sib txawv. Anisotropy yog pom tau yooj yim tshaj plaws nyob rau hauv ib qho crystals ntawm cov khoom los yog cov tebchaw, nyob rau hauv uas atoms, ions, los yog molecules yog teem nyob rau hauv tsis tu ncua lattices.

Vim li cas anisotropic siv hauv qhov xwm txheej?

Nqe lus no txhais li cas? A 1. Nqe lus txhais tias qee yam ntawm lub cev zoo lihluav taws xob tsis kam lossis refractive Performance index ntawm Crystalline Solids qhia qhov sib txawv thaum ntsuas raws cov lus qhia sib txawv hauv tib lub crystal.
