  1. 不像押针注射器制成的玻璃,制造的特种塑料注射器系统(CZ,大京)不利用钨针,以创建一个插入针开幕。

    Unlike staked needle syringes made of glass , manufacture of the specialty plastic syringe system ( CZ , Daikyo ) does not utilize a tungsten pin to create an opening for inserting the needle .

  2. 不使用填充焊丝,当焊接电流为45A、钨针直径为1.6mm、保护气体流量为15L/min时,AZ31镁合金薄板氩弧焊接头的力学性能可达到母材的79%左右。

    Without welding wire , the joint strength is about 79 percent of the base material at 45A welding current . The joints strength is increased with welding wire .

  3. 采用电镀方法和直接刷涂的方法在钨针衬底和硅衬底上沉积高压合成的金刚石粉末形成冷阴极。

    Electroplating and direct brushing technique were used to deposit commercial HTHP diamond powder on W needles and Si substrates to form cold cathodes .
