Piv nrog rau cov ntsuas hlau thiab marble gauges, ceramic gauges muaj siab rigidity, siab hardness, siab ceev, tsis tshua muaj thermal expansion, thiab me me deflection los ntawm lawv tus kheej qhov hnyav, uas muaj zoo heev hnav tsis kam.Nws muaj siab hardness thiab zoo heev hnav tsis kam.Vim qhov me me thermal expansion coefficient, qhov deformation tshwm sim los ntawm qhov kub thiab txias hloov me me, thiab nws tsis yooj yim cuam tshuam los ntawm kev ntsuas ib puag ncig.Kev ruaj ntseg siab yog qhov kev xaiv zoo tshaj plaws rau ultra-precision gauges.
