availability coefficient 中文意思是什麼

availability coefficient 解釋
可用系數, 資用性系數
  • availability : n. 1. 有效，有益，可利用，可得到。2. 可得到的東西[人員]。3. （候選人的）當選可能性。
  • coefficient : adj. 共同作用的。n. 1. 共同作用；協同因素。2. 【數，物】系數，率；程度。
  1. In addition, the approximate formula for coefficient k p, ki, kd is also suggested by using characteristic index of forecast control. finally, through emulation, the fractional - order pi ~ d ~ arithmetic is compared with the integer - order pid arithmetic. the availability of the strategies and stability of systems are proved by doing some analysis and simulation

    然後利用根軌跡的方法分析了擁塞控制系統的穩定性，並在此基礎之上採用廣義預測控制方法所應用的特性指標求出了k _ p ， k _ i ， k _ d的近似計算公式。
  2. Finally, two examples show that, the availability and practicability of the new model is verified. the analysis of calculation result of berthiervill test embackment shows different part of compression curve have different influence upon the course of consolidation, and correct coefficient and viscous effect have great significance on deformation forecast. associated with the wenzhou airport runway engineering, the reason of increasing of pore - water pressuer in under - lying soft layer and post - construction settlement are given

    最後，通過兩個工程實例的分析來說明本文模型的有效性和實用性:一是對berthiervill填土試驗場的軟基實測數據和理論成果進行對比分析，闡明考慮結構性擾動和粘滯性效應對分析天然粘土固結壓縮性的重要性;二是對溫州機場袋裝砂井超載預壓工程進行數值模擬，指出停荷預壓期間下臥層孔壓增加和工后沉降大的原因。
  3. In view of improving the efficiency of fertilizer, we paid more attention to the effect of water dynamic process and strength on nutrient availability. in this research, by model test, four kinds of agricultural soils were studied, concerning about the effect of drying - wetting alternation and temperature on potassium availability, ions " diffusion in soils under different levels of water content, and the distribution coefficient of potassium between solution and soil phases

    因此，本研究通過室內模擬土壤水分的動態變化，對水分變化的過程（干濕交替不斷進行）和變化強度對養分有效性的影響，不同水勢狀態下養分離子在固、液相間的分配關系，以及不同水分條件下養分的擴散遷移規律等方面進行了探討。
  4. Coefficient of availability of vehicle

    車輛完好率
