在相同循環噴油量和相同轉速的條件下，隨著添加劑質量分數的增加， hcci著火和燃燒放熱提前，燃燒放熱峰值提高，低負荷工況范圍明顯拓寬，但過高的添加劑質量分數會使得發動機爆震，工作粗暴，導致高負荷工況變窄。First, according to the demand of vimp for resin system, the reaction kinetics and rheological of up resin are investigated and the optimal content of low additive profile ( lpa ) is determined. then vimp based on a high - permeable medium and grooves are studied by visual experiments, through which the appropriate high - permeable mediums are selected and the parameters of width, depth and spacing for flow grooves and spacing for supply grooves are optimized. furthermore, various factors affecting the mold filling process are discussed and the whole vacuum infusion procedures are described taking examples of the manufacture of a model boat and a sandwich panel in one infusion
文中首先根據vimp對樹脂體系的要求，對vimp用不飽和聚酯樹脂體系的動力學和流變學性能進行了研究，確定了最佳低收縮添加劑的含量；對高滲透介質型和溝槽型vimp開展了實驗研究，通過可視化實驗優選出較好的高滲透介質，確定了引流槽的寬度、深度和槽間距及主槽的槽間距等工藝參數並進行了優化；對影響充模過程的各種因素進行了詳細的討論，並以模型船和夾芯面板的製作為實例描述了兩種vimp的成型過程；在實驗的基礎上，建立了二維滲漏模型，採用控制體有限元法對高滲透介質型vimp進行了成型過程的計算機模擬計算，通過充模時間和流動前峰的計算值與實驗結果的比較，驗證本文所採用的數學模型和數值方法的正確性，其結果對實際生產具有一定的理論指導意義。Peg and superfluous aa reaction by complete concatenation method, the esterify production " esterify water " and acid number were mensurated, it shows that the esterify reaction would be processed under 100 esterify temperature and with amine accelerantthe tide of esterify reaction was substantiated by ir. in the ir spectrum, the characteristic peak of hydroxy of peg and carboxyl of aa were weakened. and the ester link of peg was reinforce. the " esterify water " was increased gradually and the acid number of esterify production was debased gradually along with the extent of esterify time and the augmentation of molecular weight of peg
通過聚乙二醇與過量的丙烯酸採用全連續法進行反應，測定酯化產物「酯化水」和酸值等宏觀手段反映出在胺類促進劑、 100的酯化溫度等條件下的酯化進程，而利用紅外光譜（ ir ）分析所反映的聚乙二醇的羥基和丙烯酸的羧基特徵峰減弱，而pea的酯基特徵峰加強等特徵進一步證實了宏觀手段所表現出來的酯化趨勢：隨著酯化時間的延長和聚乙二醇分子量的增大，產生的「酯化水」逐漸增加，酯化產物的酸值逐漸降低；從酯化時間看，當反應時間達到300min時，酯化物的酸值達到最小，而從ir分析來看，酯化物pea4的羥基峰在300min時減弱到最小， pea23在120min時羥基峰的表現出酯化基本完全。By choosing different solvents, concentrations and temperatures, and using nmr spectrum technique, to determine the hydroxyl of z / e isomers of perillartine, the concentration of which was 3. 125 mg / ml, present different chemical shifts in c6d6, solvent and carbon tetrachloride and in the 1h nmr, and accordingly, conduct qualitative and quantitative analysis of z / e isomers of perillartine
摘要本文利用核磁共振波譜儀，通過對紫蘇葶溶液不同溶劑、不同濃度和不同測試溫度的選擇，使順式結構和反式結構的紫蘇葶羥基峰在核磁共振維氫譜中呈現出不同化學位移值，從而對其順式結構和反式結構進行了定性、定量分析。Clinical dosimetry ; applications of x - rays with peak voltages between 10 and 100 kv in radiotheraphy and soft tissue diagnostics
臨床劑量.第4部分:放射療法和軟組織診斷中峰值電壓1If syringe injection, which is irreproducible at the high pressures involved, must be used, better quantitative results are obtained by the internal calibration procedure where a known amount of a noninterfering compound, the internal standard, is added to the test and reference standard solutions, and the ratios of peak responses of drug and internal standard are compared
如果要使用注射器注射劑（在高壓下無法再生） ，通過內部校對規程會得到更佳定量的測定結果，在內部校對規程中，已知數量的非干擾化合物（內部標準品）被添加到測試品和標準參考溶液中，可以比較藥品和內部標準品的峰值響應比率The numerical modeling results show that the smaller the elastic modulus of adhesive in fillet, the higher the peak stress in adhesive layer at the adjacent point to the fillet when hi - adhesives used to form the fillet and bondline respectively and is higher than that of the joint made of single adhesive
