求翻译：如果提高硬度，会影响到电阻等一系列其它参数的变化，加入改变了关于硬度的要求，需要逐一确定其它参数之间的影响，需要很长时间才能确定下来，甚至需要通过一定的实验来确认，目前的产品性能良好，没有必要再对原有的参数进行变更。是什么意思？

If you increase the hardness, the change will affect the resistance such as a range of other parameters, changed the requirements on hardness, you need to determine the influence of other parameters, take a long time to be finalized, even through some experiments to confirm the good performance, the

If you increase hardness, impact resistance, and to a range of other parameters change, to change the hardness of the requirements, you need to determine if the Additional Parameters one by one the impact between, take a long time to come up, and even through a set of experiments to confirm that the

If enhances degree of hardness, can affect the resistance and so on a series of other parameter change, joined changed about degree of hardness request, needed to determine one by one between other parameters the influence, needed the very long time to be able to determine, even needed to confirm th

If hardness, affects a number of other parameters such as resistance change, join the change request on hardness, you need to determine the effects of other parameters one by one, take a long time to be finalized, even needs certain experiments to confirm that current product performance is good, th
