lagged value 中文意思是什麼
-
The toxicity peaks always lagged the growth peaks, furthermore, the greater the biomass, the longer the lagging days. both mc - rr and mc - lr gave rise to their maximum value at the end of every single bloom and soon after a new bloom began. in general, the ratio of mc - rr and mc - lr remained comparatively constant during every bloom, but no obvious change characteristic was observed on mc - yr content. in the discussion, in was found that toxin - producing of microcystis was related to biomass, nutrients and water temperature
分析各個階段的水華，我們發現毒性峰總是滯後於生長峰，且生物量越大，滯后的時間越長； mc - rr與- lr的含量在每個階段水華的末期達到最大，之後新一輪的水華開始出現，並且mc - rr與- lr的比例保持基本恆定，但是mc - yr的變化無明顯的規律。 -
At the same time, it brings the greater displacement reaction, lower energy - dissipation capacity and badly ductility ability etc. the unbonded partially prestressed concrete flat - beam frame structure has been used in the practice project in our country, but the aseismatic study of this structure is not perfect at present, study on theory is lagged behind the demand of engineering apply. it has important theoretic meaning and applied value to go deep into the examinational study about the prestressed concrete flat - beam frame structures
近年來國內已經開始在實際工程中採用無粘結部分預應力混凝土扁梁框架結構，但是目前對這種結構形式的抗震研究工作還不完善，理論研究已滯後於工程應用的需要，因此深入進行扁梁框架結構的研究，在經濟合理的情況下確保該結構的抗震安全性具有重要的理論意義和應用價值。
