Abstract:
     This inventon relates to the synthesis of a new liquid crystal compound at low temperalure,i.e.,cholestrol-ethyleneqlycol-diethylether-phthalate.The temperature of liquid crystal is -19 deg.c.there are 184 prezcriptions of cholest liquid crystal which siut for no-damage test.The temperature of the liquid crystal ranges from 5 deg.c to 100 deg.c,sensitivety 0.01 to 44deg.c.When testing aluminium cover honeycomb latice degum in whirling wing of helicopter,0.5cm degum point is measured within a second.This method can also be used to test crack in titanium propella dynamically.
