本論文建立在已有的港口裝卸機械管理的研究基礎之上，進一步提出了以可靠性為基礎的港口裝卸機械的管理思想，已有的研究表明，港口機械設備破壞主要由於兩個原因，第一是穩定性問題，特別是構件的局部穩定性，所謂穩定性是指：在板的平面內，板受到平行於板面的壓力作用，使板發生隆起、內陷等凹凸不平的結果，從而使板受載能力減弱；第二是結構出現疲勞裂紋及其擴展，這是由於設備長時期運行，而造成設備某些部位出現裂紋並得以擴展，使設備承載能力下降。According to the research of physiological and biochemical indicators or index, components of soluble proteins, substrate protein of phosphorylation and the activity of protein kinase in low - temperature stress in the leaves of brassica oleracea l., we tried to find the law of the physiological and biochemical response of brassica oleracea l. leaf to low temperature. at the same time, discussion on the signal transduction can also provide further evidences for revealing the mechanism of low - temperature stress. the results are showed as follows : malondialdehyde ( mda ), superoxide dismutase ( sod ), ascorbate peroxidase ( asp ) and peroxidase ( pod ) activities were changed greatly after 0 ~ 30min ' s treating with low temperature
