Chillness intensified the senesce of leaves, enhanced the MDA content and the O2-. produce rate, this was more evident in Shanyou63.

低温处理加剧了叶片的衰，MDA含量和O2-产生速率上升，两优培九的升幅较汕优63小。

An MDA is the lowest permissible height (in a nonprecision approach) at which an aircraft can be controlled by reference only to instrument information.

最低下降高度是在仅照仪表信息就能操纵航空器时的最低允许高度(在非精密进近中)。

In the group of dicoumarol plus doxorubicin, serum ALT, LDH, CK activities were significantly increased as compared with that of doxorubicin group alone, and liver MDA content was also increased.

与单素组比较，双香豆素能显著增强素所致的血清ALT、LDH、CK催化活性升高，肝MDA含量也增高。
