It is shown that phase space flux is growing continually along with significant wave height and the safe basin of ships is decreasing rapidly.
研究表明：随有义波高增大，相空间转移率不断增大，船舶航行的安全域迅速减小。

Furthermore, the deposition rate increases per unit of welding current by decreasing wire diameter, and adjustment of the penetration depth is enabled by alternating current wave form and polarity.
减少焊丝直径，能提高熔敷效率，再加上使电流波形交流化，就可以调整熔深。

It also has special advantages of decreasing energy of wave upward and surface damage, avoiding punching, eliminating flying-rock risk and enhancing security.
