求翻译：试验中采用的是化学镀Ni-P合金基础镀液、化学复合镀Ni-P-PTFE复合镀液，在总施镀时间不变的前提下，通过改变化学镀和复合镀的Ni-P-PTFE施镀时间，控制两种不同镀层的厚度进行试验，试验方案如表1所示：是什么意思？

The trials used in the electroless plating ni-p alloy plating bath, the composite plated ni-p-ptfe composite plating bath, under the premise of the total plating time constant, change the plating and composite plating ni-p- The ptfe plating time, control of two different coating thickness test, the

Testing of the chemical nickel-based alloy P Ni - nickel plated fluid, chemical compound Ni - P - PTFE composite coating fluid, plated in the overall rate of time does not change, by changing chemical nickel composite plating and the Ni - P - PTFE rate nickel-time control, two different plating thic
