中文拼音 [làtǐjiāsùdù]
落體加速度
英文
acceleration of falling body-
The results showed that the gradation, which designed by volumetric methods, has perfect water - stability and other pavement performance also can meet the demands of expressway. by integrating compaction capacity and pavement performances, the optimal ratio of the structural layer thickness to the maximum particle - size is 2. 5. the water resistance of the mixture added amine type anti - stripping agent attenuates severely after long - term aging, but the mixture added hydrated lime not only can improve obviously the capacity of water resistance, but also has perfect long - term pavement performance
研究結果表明，採用體積法設計的級配不僅具有較好的水穩定性而且其它路用性能均滿足高速公路面層的要求；綜合考慮壓實性能及路用性能，提出了瀝青路面表面層結構層厚度與混合料最大粒徑的合理比例為2 . 5 ；摻有液體胺類抗剝落劑的瀝青混合料經長期老化后其抗水損害能力衰減嚴重，而摻加消石灰的混合料能顯著提高其抗水損害能力，且長期性能較好，是一種優良的抗剝落劑。Then, we use a simulation method to create a large number of radar measurement values, produce a quantity of random numbers using computer software and add them to the radar measurement values, we use kallman filtering method to calculate the location, velocity and trajectory coefficient of the target at the moment of the final tracking point, and use the numerical solving method of differential equation to calculate the trajectory, the location of the hostile artillery or the impact point of its own projectiles, finally, we calculate statistically the random error of the tracking system and analyze the location accuracy
然後採用模擬模擬方法獲得大量的雷達測量值，由計算機軟體產生大量的隨機數，加入雷達測量值中，用卡爾曼濾波法計算出最後跟蹤點時刻的目標位置、速度和彈道系數，再用微分方程數值解法計算出整個彈道軌跡、計算出敵方炮位的位置或己方炮彈的落點，最後統計出跟蹤系統的隨機誤差，分析定位精度。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。The impetus of its advance is increased as it approaches its goal, just as the velocity of a falling body increases as it gets nearer the earth
法軍愈接近目的地，其勢愈猛，如物體落地時的加速度一般。Now for a long time, it has been very popular lhat the cracks from the cornmodity concrete and high shump concrete appear during constructions. in addition, the thermal release speed of the cement is comparatively much fester than that in the past, causing the problem of the thermal crack in the mass concrete rnore serious
目前建築施工中普遍使用的商品混凝土和大坍落度混凝土的開裂現象一直比較普遍，加之現在所生產的水泥放熱速度較過去大為提高，這使得大體積混凝土的溫度裂縫問題日益突出，已成為普遍性的問題。The statement should be qualified and should specify that all bodies fall at the same rate in a vacuum.
這個論述應加以限定，並修正如下：所有物體在真空中以相同速度降落。分享友人
