The results can be extrapolated to zero thickness to obtain the correct surface strain . 将此结果外推到厚度为零的情况,以获得正确的表面应变。
It is advisable to employ a strain gage of one form or another to measure the surface strains directly . 最好是用这样或那样的应变计把表面应变直接测出来。
" ubridge brand " marble mostly to use in slagging powder with drug cover welding electrode . improve slag basicity , steady arc , increase surface strain . it also used on architecture industry 粤桥牌大理石粉为白色或浅灰色矿粉,主要用于药皮焊条等焊接材料的造渣造气剂,可提高熔渣碱度稳
