1·The laser-arc hybrid welding can improve the depth of fusion, welding speed and assembly gap, so it is a new and promising thermal source for welding.

激光-电弧复合热源焊接可以增大焊接熔深，提高焊接速度，增大装配间隙，是一种很有前途的新型焊接热源。

2·And the effect of SPreading fusion of active flux on weld pool depth and arc phenomenon in A-TIG welding is also studied with properly experimental method.

采取适当的试验方法研究A- TIG焊活性剂对电弧现象及活性剂涂敷量对焊接熔深增加的作用。

3·It is shown that the shape of the oscillating curves of the output power versus the elongation length and its depth of modulation are influenced by the fusion temperatures.

结果表明，熔烧温度影响输出功率随拉伸长度振荡的曲线形状及调制度。

4·Tritium is very important fusion materials, it has been broad applied both in military area and in civil area. It is very important to study the depth profile and composition of tritium in materials.

氚是一种重要的聚变材料，在军事和民用方面都有广泛的用途，氚在薄膜靶中的浓度和深度研究是一项重要的课题。

5·Heater leak occurs by direct reason of the stress corrosion cracking, while by other reasons of solidification cracking, small fusion depth of welding joint and non...

应力腐蚀裂纹是造成加热器泄漏的直接原因，结晶裂纹、焊缝熔深小及坡口底部未熔透也是加热器泄漏的原因。
