配子擴散 的英文怎麼說
中文拼音 [pèizikuòsǎn]
配子擴散
英文
gametic dispersal-
The intramolecular vibrational redistribution ( ivr ) and the ultrafast solvent inertial relaxation should account for the faster decay, while the slower decay is attributed to the diffusive solvent relaxation
快速弛豫過程來源於分子內振動能量再分配（ ivr ）和溶劑分子超快慣性弛豫動力學過程，而慢速弛豫過程對應于溶劑化的擴散分子弛豫動力學過程。Water cement ratio and mixing fly ash or slag into concrete effect on ability of resisting chloride penetrating that are considered in the model. the effect of environment that include temperature, relative humidity and cumulating of surface chloride concentration of concrete are also considered. moreover, chloride diffusion changing with time is included in this model as well as
模型中考慮水灰比和混凝土配合比（摻入不同量的粉煤灰和礦渣）變化對混凝土抵抗氯離子侵蝕能力的影響，同時考慮溫度、相對濕度和表面氯離子濃度累積變化等環境因素對氯離子侵入混凝土過程的影響，以及氯離子擴散系數隨時間的變化。The concrete used in testing bridge is monitored and some performance at definite age including compressive strength, splitting fensile strength, frost resistance, scaling frost resistance, chloride ion diffusion coefficient ( dcl - ), resistance of carbonization and pore structure by mercury porosimetry are tested. these performances are compared with that of concrete which designed by traditional method. the results show that mechanical properties of concrete designed by high durability concrete proportion and traditional method meet require ment at any age, however, frost resistance, scaling frost resistance, chloride ion diffusion coefficient ( dcl - ), resistance of carbonization and pore structure of the former are better than the latter, so high durability concrete is economic benefit
對試驗橋用混凝土的質量進行監控，並成型試件測量所需齡期內的抗壓強度、劈裂強度與抗凍融、抗鹽凍、氯離子擴散系數（ dcl - ） 、抗碳化等耐久性能指標及孔結構，並與傳統混凝土進行對比研究，結果表明:高耐久性混凝土及按傳統配合比設計的混凝土的力學性能均能滿足相應齡期的要求，但前者的抗凍融性能、抗鹽凍性能、抗碳化性能、 dcl -和孔結構明顯優於後者，並具有明顯的社會經濟效益。These equipments are vacuum system which is made up of diffusion pump, pipes, water - cooling baffle and rotary vane pump ; the whole chamber, wall and water - cooling wall are made of stainless steel ; the lower part is equipped with cool water sleeve which can fast take out air to gain 10 - 4 or higher vacuum, therefore they are widely used in high - tech fields, such as the platting, electronic, metallurgy, chemical engineering, atomic energy, materials and medicine etc
Kt系列擴散泵機組是由凸腔擴散泵管道水冷擋板機械泵等組成的高真空系統，整個泵腔泵壁及水冷壁全部由不銹鋼作成，下部配有降溫用急冷水套，抽氣速度快，極限真空高，它可使被抽容器獲得10 - 4或更高的高真空，因此廣泛適用於鍍膜裝飾電子冶金化工原子能材料醫藥等等各種高新技術領域。6. the durability of concrete structures resisting chloride diffusion in different water cement ratio and different contents of fly ash and silica was analyzed and durable life was predicted based on the results of the test, which will be helpful to preparation of high performance concrete ( hpc ) as well as durability design and assessment of concrete structures
系統地研究了低水膠比及摻加粉煤灰、硅灰的高性能混凝土的電滲透性和氯離子擴散系數，分析了水膠比以及粉煤灰和硅灰等活性集料對混凝土結構抵抗氯離子侵蝕的耐久性能的影響，並對高性能混凝土結構抗氯離子侵蝕的耐久壽命進行了預測，為氯鹽污染環境下高性能混凝土的配製以及混凝土結構耐久性評估與設計提供參考。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。分享友人
