shallow penetration meaning in English

浅穿透曲线

Unlike a light bulb , however , active denial technology will not cause rapid burning , because of the shallow penetration of the beam and the low levels of energy used
但是，与触摸灯泡不同的是，由于该技术产生的毫米波波束的较浅穿透深度和较低的电磁能量而不会快速烧伤皮肤。
The dcep mig has the characteristic of deeper penetration which can reduce defective fusion and good arc stabilization . the dcen mig has the characteristic of shallow penetration of welding seam , and the welding wire has a high melting speed . so the variable polarity pulsed mig is a new technology for the welding of aluminium alloy sheet
变极性脉冲mig焊是一种新的焊接工艺方法,其综合了dcep脉冲mig焊熔深较大、可以减少焊缝的熔合不良、电弧稳定性好和dcenmig焊焊缝熔深浅、焊丝熔化速度较快的特点,减小了焊缝的熔深,增加了焊丝的熔化速度,是一种适合于薄板铝合金焊接的新方法。
