中文拼音 [zhòuyèdòngtài]
晝夜動態
英文
diurnal dynamics-
With the fuzzy theory and the dew point confined, the system can automatically adjust the surrounding temperature and humidity in the workshop to the set - point, no matter what the outside condition is, such as the change of temperature in winter or summer, in day or night, and the asymmetry of the machine and the pyrotoxin
研究出適合計算機控制的溫濕度控制模型，通過模糊控制邏輯和露點限制，自動適應冬夏氣候變化、晝夜溫差變化、車間機器分佈和發熱不均等復雜工況。實現多工況多控制狀態的自適應控制，車間主控區溫度1 ，濕度4的控制目標。The research include : 1 ) measuring co2 concentration in the soil air and vegetation air by using co2 measuring instruments ; 2 ) measuring the releasing rate of co2 coming from soil surface by using alkaline absorbing method ; 3 ) measuring the hydrochemical indexes of soil water. the research results are as follows : ( 1 ) the author has made field observation of depth distribution of soil air co2 in the mt. jinfo karst experiment site. the results show that two concentration gradient, soil to atmosphere and soil to carbonate rock, are form
本次實驗以典型的亞熱帶巖溶分佈區?金佛山自然保護區為例，選擇了巖溶窪地內的高山草甸和靠窪地邊緣地帶的方竹林、裸地以及石林內的喬木林4個樣地，對土壤co _ 2濃度空間分佈規律以及晝夜動態和日動態變化狀況進行了觀測，獲得了如下新的認識： （ 1 ）土壤中co _ 2濃度分佈的觀測結果表明，土壤中具有土壤-大氣、土壤-碳酸鹽巖兩個方向的co _ 2濃度梯度。( 3 ) the diurnal observation results of soil co2 dynamics in the field display the variation of soil co2 concentration and the releasing rate of co2 coming from soil surface is controlled by temperature. the correlation between co2 concentration in the top soil and temperature is very significant
（ 3 ）土壤co _ 2濃度和土壤釋放量晝夜動態變化均受溫度控制。土壤co _ 2濃度中義摘要變化與溫度相關分析結果表明，土壤表層co 。濃度的變化與溫度相關性顯著。But variation of the co ; concentration in the bottom soil show that sink effect of carbonate rock on the soil air co2 ( 2 ) the diurnal observation results of soil co2 dynamics in the different vegetation show that the soil co2 concentration in the bare land is sensitive to environment, but the soil co ; concentration in the other experimental site, which covered with vegetation, restrain the variation
在土壤?大氣界面上，土壤表層可為大氣提供游離co _ 2 ；而土壤深部co _ 2濃度的變化則顯示下覆碳酸鹽巖對co _ 2有吸收作用。 （ 2 ）在不同植被系統中，土壤co _ 2晝夜動態變化進程不同。觀測資料表明：裸地對外界環境的變化相當敏感，而有植被覆蓋的竹林和草甸對土壤co _ 2濃度動態變化有平抑作用。The community productivity, structure and succession are significantly influenced by global climate changes. this study focused on soil respiration rate of stipa baicalensis grassland by using dynamic infrared gas absorbed method. we analyzed diurnal pattern of soil respiration rate and the influences of surface soil temperature and water content for this parameter, then compared the differences between day and night soil respiration rates, and explored the correlations between aboveground and underground biomass with the soil respiration
溫帶的半乾旱、半濕潤區草甸草原屬于過渡氣候影響下形成的植被類型，對環境氣候條件變化十分敏感，為了揭示半乾旱、半濕潤區草甸草原生態系統土壤碳素釋放規律及其對主要環境因子的響應，本研究採用動態室紅外氣體吸收法測定松嫩草甸草原典型群落? ?貝加爾針茅群落土壤呼吸速率，分析了土壤呼吸速率日變化規律及表層土壤溫度和含水量對土壤呼吸速率日變化的影響，比較了土壤呼吸速率的晝夜差異，探討了地上生物量和地下生物量與土壤呼吸速率之間的相關關系。分享友人
