中文拼音 [jiāozhùmìdù]
澆注密度
英文
poured density-
The results show that, composite could be fabricated on the complicated surface by means of sodium silicate sand mold combination with vacuum infiltration process. when the substrate was 10 mm, composite layers reached 3 mm to 5 mm in thickness with high strength interface and less casting defect. microstructures of grey cast iron and low chromium cast iron matrix composites with various volume fraction has been analyzed
結果表明：用水玻璃砂型（芯）加負壓鑄滲的工藝能夠實現復雜表面（曲面）顆粒增強復合材料的制備，澆注方式簡單可靠，基材厚度在10mm時，復合層厚度能達到3 5mm ，且復合層鑄造缺陷少，復合效果好，界面緻密而且結合強度高。By employing data study, behavior study and case study this thesis thoroughly analyses and systematically elaborates the contents and the concrete manipulatary process from the practical point of view, coupled with the students " psychological characteristics in the primary stage, aimed at offering great help in implementing the chinese psychology education in primary schools
本文運用文獻法、行動研究法、個案調查法等研究方法，注重從實用的角度，全面分析並緊密結合小學生年齡階段的心理特徵、心育需求來系統闡述了小學語文心育內容及其一般操作，以期為小學語文心育之樹澆水、施肥。Model jy light thermal insulating pouring material is new irregularly setting fire - resistant material which is made from the excellent and super powerful light aggregate, super minunt material, combine agent and additional agent. this material is series of new fire - resistant lining naterial with low density, high intensity, small thermal conductivity
Jy系列輕質保溫澆注料是一種新型不定型耐火材料，由優質超強輕質骨料、超細粉、結合劑和外加劑組成，是一系列密度低、強度高、導熱系數小的新型隔熱襯里材料。The speed became fast at the temperature 1050. the reaction could carry completely when billets was kept in vacuum tube for 3 hours " at 1050 temperature, under the striking of great quantity of heat when the molten iron poured into the mold, the reaction was blazed rapidly and continued at a high speed. the diffusible speed of v and c was very fast because the billet was heated over 1300 in a moment, so the reaction ca n complete in a few minutes
（ 5 ）碳化反應v + c vc在900左右開始發生，此時是固相反應，反應速度較慢，反應不能進行完全，隨溫度升高，該碳化反應的速度加快，在1050保溫3小時可以進行完全，在鑄造燒結時在過熱鐵水的巨大熱流密度沖擊下， v + c vc立即被激發，並以很快的速度進行，由於坯塊被加熱到1300以上，此時c和v擴散速度很快，因此鑄造澆注后的幾四川大學碩士學位論文分鐘內反應可以進行完全。分享友人
