1. Kutentha kozungulira: -10°C~+40°C
2. Kutalika: osapitirira 1000m
3. Chinyezi:
Chinyezi chofanana: mtengo wapakati wa tsiku ndi tsiku supitirira 95%, mtengo wapakati wa mwezi uliwonse supitirira 90%;
Kuthamanga kwa nthunzi yokhuta: avareji ya tsiku ndi tsiku siipitirira 2.2x10-3MPa, avareji ya mwezi uliwonse siipitirira 1.8x10-3MPa.
4. Mphamvu ya chivomerezi: sichidutsa madigiri 8
5. Mpweya wozungulira usakhale wowononga kapena woyaka, nthunzi ndi zina zodziwika bwino zoipitsa
6. Palibe kugwedezeka kwamphamvu komwe kumachitika nthawi zonse pamalo ogwiritsira ntchito
Ndemanga:Ngati sichoncho ndi momwe zilili pamwambapa, zitha kusinthidwa.
