### **Mabuɗin Mahimmanci**
1. **Nazarin Waveguide**:
Ana yiwa lakabin waveguide da "WR" (Waveguide Rectangular) da lamba (misali, WR-90). Lambar tana kusantar ** girman bangon bango na ciki ** a cikin ɗaruruwan inch (misali, WR-90 ≈ 0.90" faɗin ciki).
- Misali: WR-90 = 0.9" (22.86 mm) fadin ciki.
2. ** Nau'in Flange ***:
Flanges suna daidaita haɗin kai tsakanin jagororin igiyar ruwa. Nau'o'in gama-gari sun haɗa da:
- **UG/UPC** (MIL-STD): Daidaitaccen flange na soja (misali, UG-387/UPC).
- **CPR** (Kasuwanci): Matsayin Turai (misali, CPR-137).
- ** Choke Flanges ***: Don ƙananan leka, aikace-aikace masu ƙarfi.
- ** Rufe Flanges ***: Mafi sauƙi, ana amfani dashi don rufewa.
3. **Maɗaukakin Mita**:
Kowane jagorar igiyar igiyar ruwa tana goyan bayan kewayon mitar takamamme bisa girmansa.
