求英语好的帮忙一下 急求

Sure, I'd be happy to help. It seems like you have some questions or need clarification on certain terms related to surface treatment for the supply conditions according to DIN 267. Let me break it down for you:

1. Surfacetreat: This term refers to the process of treating or coating the surface of a material. In this case, the surface treatment method used is "phosphated and oiled." Phosphate coating provides corrosion resistance and improves the adhesion of paint or other coatings, while the oil coating helps to reduce friction and prevents rusting.

2. Heat to avoid hydrogen embrittlement: This line indicates that after the surface treatment process, the treated material needs to be heated to prevent hydrogen embrittlement. Hydrogen embrittlement is a phenomenon in which the presence of hydrogen atoms weakens the material, making it more susceptible to cracking or breaking.

3. Supply conditions according to DIN 267: DIN 267 is a German standard that provides guidelines for the supply conditions of various materials. These conditions could include specifications such as dimensions, tolerances, surface finish, and any particular treatment requirements.

If you have any specific questions or need further explanation, feel free to ask!
