求翻译：我们没做过这么长时间的高温试验，不知道会有什么不良效果。但是可以在电镀时增加耐高温剂，可以避免或减少高温下材料变化是什么意思？

We did not do so for a long time high temperature test, do not know what adverse effects. But can increase the temperature in the plating agent, to avoid or reduce the changes of materials under high temperature

We had not done so long a period of high-temperature test, and do not know that there will be no adverse effects. However, it can be an increase in plating at high temperature resistant agents, can be avoided or reduced material under high temperature change

We have not performed the such long time high-temperature test, did not know can have any not good effect.But may when the galvanization increases the thermostable medicinal preparation, may avoid or under the reduced high temperature the material change

We hadn't done so a long time of high temperature test, I do not know will have any adverse effects. But can be increased heat-resistant agent for electroplating, changes can be avoided or reduced at high temperature materials

We have not done the hot test which has passed such a long time, have not known that there is any bad effect. But can increase high temperature resistant pharmaceutical while electroplating, can avoid or reduce the material change under the high temperature
