那下面这几句话你能理解吗 The term one-way forward when used where the originally installed or delivered part is the part being replaced means either the original part or the replacing part may be used. In cases where the term one-way forward is used where the originally installed or delivered part is the replacing or newer part, only the new part may be used. Operators are not locked into the new part number where the old part was originally installed. Future maintenance may use either part. Only when the new part was originally installed are operators required to use only the new part.
