Ha re nahana ka bophelo ba ts'ebeletso ea sekhechana sa potoloho, boleng bo tloaelehileng ba lihora tse 24 ha bo fete +35 ℃.
Hlokomela:
① Boemo ba ho sebetsa ba boleng bo tlase ba moeli ke -10 ℃ kapa -25 ℃.Mosebelisi o hloka ho tsebisa k'hamphani ha a reka.
②Boemo ba ho sebetsa ba boleng bo holimo ba moeli bo fetang +40℃ kapa boleng bo tlase ba moeli bo ka tlase ho -25℃, mosebelisi o hloka ho buisana le k'hamphani.
2) Sebaka sa ho kenya
