熱力蝕變 的英文怎麼說
中文拼音 [rèlìshíbiàn]
熱力蝕變
英文
thermal alteration-
With the very low water to cement ratio, rpc has ultra - high strength high ductility and low permeability. in this paper, the compressive strength of rpc can reach to a high point with the number approximately 135mpa. as illustrated from the study results, we can approve some fundamental conclusions : there are big effects on rpc with deferent kinds and properties of raw materials and deferent curing conditions ; stress - strain curve shows the process of destroy with rpc samples ; x - ray diffraction analysis indicates that heat treatment at temperatures 90 accelerate the hydration of rpc sharply, therefore, mechanical and microstructural properties of rpc are highly dependent on heat treatment ; it is believed that rpc materials have excellent resistance to chloride permeability ; during the heat treatment, the shrinkage of rpc developed quickly because of chemical reactions ; the rpc with slag mostly has the advantage of rpc without slag about resistance to solutions corrosion
研究結果表明：通過對rpc各組分摻量變化的研究，可以找到rpc的最優配合比；試件成型后的熱養護制度對rpc的性能影響巨大； rpc的抗壓應力?應變曲線可以反映出試件受破壞時微裂紋的擴展情況，剛纖維的摻入可以大幅改善rpc的韌性； rpc在成型后存在較大的收縮，而其中的化學收縮要遠遠大於乾燥收縮； rpc具有很強的抗氯離子滲透性能，漿體的密實度很高；通過x射線衍射實驗，可以發現rpc的膠凝體中ch晶體已經幾乎不存在，膠凝體主要由c - s - h凝膠和未水化水泥顆粒組成；在抗溶液侵蝕的實驗中，摻礦渣rpc的抗溶液侵蝕性能在絕大多數情況下要好於不摻礦渣試件，酸、堿溶液和浙江工業大學碩士學位論文摘要一些鹽溶液都會對rpc的結構產生侵蝕作用，但是機理各有不同。This is due to the higher weathering resistance of hydrothermally altered rock.
這是由於熱液蝕變巖石具有較高的抗風化力的緣故。3. bring forward a new idea : the ideology of synergetics used in atomic simulation and multi - scale simulation of materials design. on the basis of this, next tasks were put forward : ( 1 ) analyzing the changes of stress - strain curves of the interphase before and after pre - treatment ; ( 2 ) the efficient of the coupling effect of o2, na2s04 and h2o stream on the oxidation and erosion resistance of interphase ; ( 3 ) the methods of improving environment performance of interphase above 1273k
提出將協同學的思想用於原子級模擬及跨尺度模擬的思路，並在此基礎上，提出下一步的工作設想： （ 1 ）分析熱處理前後界面相區域應力-應變曲線的變化； （ 2 ）航空發動機模擬環境中，氧、硫酸鈉蒸汽及水蒸汽耦合效應對界面相抗氧化性、抗腐蝕性的影響； （ 3 ） 1273k以上界面相環境性能提高的方法。It tell us : the abrasive capability of fly ash ; the similar calculation of ash erosion ; the calculation of ash erosion in the tube in turn and tube out of turn ; the reason of tube abrasion for gas flue ; the influence of air parameter for fly ash erosion ; the influence of changing temperature ; the influence of the flue gas composition, etc. next, it advances the solving measure ; reduce the flue gas velocity ; reduce the concentration of fly ash ; responsible construction : replace smooth tube with spiral tube ; use the new material of abrasion ; fuel desulfurization ; reduce so3 of flue gas ; raise flue gas temperature, making it up the dew point ; use the abrasion - resistance material to resist abrasion
討論了飛灰磨損性能、管壁受飛灰沖蝕的近似計算、灰粒對順列管和錯列管的磨損計算、煙氣走廊引起對流管束的磨損機理、空氣動力參數對飛灰沖蝕的影響以及受熱面壁溫變化及煙氣成份對飛灰磨損的影響等問題。接著提出了解決的措施：降低平均煙氣流速；降低飛灰濃度；使用鰭片管、螺旋翅片管代替光管；選擇合適的結構及排列方式，減少煙氣中so3的含量；提高受熱面壁溫使之大於煙氣的露點溫度；採用抗腐蝕材料作受熱面等防腐蝕的措施。Flow meters may be affected, giving incorrect reading. the rate of corrosion of pipeline may also increase. the abnormal current induced in power grids may damage transformers because of overheating
流量計可能會受到干擾，使數據失誤管道的腐蝕速度亦可能會增快電力網路上的不正常電流可能使變壓器因過熱而燒毀。分享友人
