求翻译：3、上游文件TS-1-NIEP-TPZP-DC-20058附录A中ECS编码为非PF类的编码如何与图纸上的PF类编码对应（如：附录3中黄色标底部分），同时给出附录3中所有物项的编码。是什么意思？

Upstream documentation ts-1-niep-tpzp-dc-20 058 Appendix a the ecs encoding a non-pf class coding corresponds to how the the pf coding in the drawings (such as: yellow base price of Appendix 3), is given in Appendix 3, the coding of all items.

3 - 1 - TS , NIEP upstream documentation - TPZP DC - 20,058 - in Appendix A ECS encoded as non-PF category with drawings on how the encoding of such coding PF counterpart (e.g. : yellow tenders in Appendix 3, and at the same time giving out part) in Appendix 3 of all coding.

3rd, upstream document TS-1-NIEP-TPZP-DC-20058 in appendix A ECS code for non-PF kind of code how with blueprint on PF kind of code correspondence (for example: The appendix 3 decadent minimum acceptable bid parts), simultaneously give an appendix 3 possession code.

File TS-1-NIEP-TPZP-DC-20058 in the upper 3, Appendix a of the ECS are encoded in encoding non-PF and PF on the drawing class code (as in: yellow tender section in Appendix 3), and gives the encoding of all the items in Appendix 3.
