Typically, however, broaching also involvesmultiple passes.bubbler, na sampling device consisting of a gas dispenserimmersed in an absorbing liquid. D1356coining

37、, va closed-die squeezing operation in which allsurfaces of the work are restrained (coined).DISCUSSIONCoining often imparts a pattern or shape onto theworkpiece. Coining also refers to a press-brake bending operation inwhich the punch bottoms against the workpiece and the die. It alsorefers to a pr

Signs and symptoms that typify theinitial onset of dermatitis include: erythema (redness); edema (swell-ing); pruritis (

46、itching); and vesiculation (pimple-like eruptions). Inmore severe cases, fissures (deep cracks) and ulcers (open sores) maydevelop. The condition is usually reversible when exposure to thecausative agent ceases. More severe cases may require more time andsome medical attention. Some individuals may
