ʻO ka hanaʻenehana wela e holomua ana no ka hanaʻana i ka hana | Shangdong Yeuheng

ʻO nā mea hana wela wela e lawe ana i nā metatric hoʻokō me ka hoʻopiliʻana i ke ola momona (L10 helu), e komo i ka pale. Manaʻo nā mea hana hou ± 3 ° C mahana a kaʻina hana cpk≥1.33. ^. Nā leka uila: ʻO ka hoʻokaʻawaleʻana i kahiʻano.
