The important meaning in which this direction studied has lain in establishing the connection between the material science of concrete and civil engineering, analyse the strength in terms of material microcosmic or the mesoscopic, have important meaning to understanding, know the essential law of the strength of concrete. this text divides six chapters altogether. chapter one reviewed the pore structure in nowadays domestic and international research current situation, including the concrete examines research, research of the pore structure model and the research current situations of pore structure and strength relation of the pore method, have introduced some most important achievements of structure research of pore ; chapter two narrated much yardstick of the material mesoscopic structure of concrete and principle of examining pore technology of material of concrete, and the commonly used sign parameter in discussedding the pore and material pore of quito of cement and analyse, have explained that the influence factor of mip to the result of study of pore, has pointed out the limitation in mip in the pore structure ; analyse porosity and strength relation development course of model emphatically, and has carried on comparative analysis to the existing model, has pointed out the weak point of the original model ; on the basis of " ing integrate synthetically ", propose concrete pore structure compound body model and pore physical model of systemlex body ; chapter five carried on the corresponding test data to compares to the model parameter appearing in model of chapter four with and analyses, have received k value of the characteristic of strength of matrices of reflecting according to the method to return to analysis, and calculate the influence produced on the strength of concrete in revision that can probed into the content of cement, elastic mould and surface energy, exactness of the inspection model ; chapter six is the conclusion, according to studying the survey this text to some research conclusions of the pore structure and making corresponding prospect to the structure development of pore
第一章回顧了孔結構在當今國內外的研究現狀,包括混凝土測孔方法的研究、孔結構模型的研究及孔結構與強度關系的研究現狀,介紹了孔結構研究方面的一些最重要的成果;第二章敘述了混凝土材料細觀結構的多尺度性及混凝土材料測孔技術的原理,並討論了水泥基多孔材料孔隙分析中常用的表徵參數,也說明了壓汞法測孔對研究結果的影響因素,指出了壓汞法在孔結構研究中的局限性;第三章是著重分析了孔隙率與強度關系模型的發展歷程,並對已有的模型進行了比較分析,指出了原有模型的不足之處;第四章在「綜合集成」的基礎上,提出了混凝土孔結構復合體模型和孔系統的物理模型,並模擬了該模型下由各單體並聯形成的復合體的斷裂過程,最後根據所建模型編制了相應的計算程序,可根據輸入的孔徑分佈與水泥含量等參數,實現混凝土理論強度的計算;第五章對第四章模型中出現的模型參數進行了相應的試驗數據對比分析,根據回歸分析的方法得到了反映基體強度特徵的k值,並從理論上探討了水泥含量、彈性模量和表面能的修正對混凝土強度計算產生的影響,檢驗模型的正確性;第六章是結論與展望,根據研究綜述了本文對孔結構的一些研究結論並對孔結構發展作了相應的展望。The crabs were dissected respectively after one week of treatment, and the ovaries were kept in 70 % ethanol with 50mmol / l edta
一定濃度范圍內的汞處理雌蟹,譜帶差異與其它濃度處理組同正常織相比較大。This correlation exists not only between different organs but also in the same organ. the mol - ratio of selenium and mercury is about 1 : 1 in liver, gland, spleen, stomach and lungs when selenium and mercury were administered simultaneously with 2 : 1 mol - ratio, especially in stomach. and female rats have the higher probability of 1 : 1 mol - ratio accumulation of selenium and mercury than male ones
本文首次報道了除肝臟和腎臟外,大鼠心臟、大腦、胸腺、肺、脾、胃、肌肉、睪丸等組織之間及同一組織內,汞與硒含量呈高度的正相關性;當硒、汞聯合高劑量組注入大鼠體內時,肝臟、胸腺、脾、胃、肺等組織中硒、汞以大約1 : 1摩爾比的特徵積累,尤其在大鼠的胃中,硒、汞的積累方式更容易表現為1 : 1摩爾比的形式;同時,雌性大鼠體內硒、汞以1 : 1摩爾比形式積累的幾率比雄性大鼠為大。Metal masteries, for example hg, ag, pb, cd, as, cr, ni, are harmful to dna, rna, enzyme, protein and cell membrane and will cause the taking place of cancers and mutations of them. so the normal metabolize and split are damaged, the immunity function, the anti - cancer function will be weakened. it is very difficult to be cured once he or she is toxic
金屬汞、銀、鉛、鎘、砷、鉻、鎳等對dna 、 rna 、酶、蛋白質以及細胞膜的損傷非常大,從而引起它們的致癌、致突變作用,以破壞細胞的正常代謝和分裂;降低機體的免疫功能、防癌和抗癌能力,一旦中毒是很難治愈的。The results showed that the interaction between selenium and mercury in rats mostly is the antagonism on the both acute toxicity tests and sub - chronic ones. liver, kidney, gland, heart, spleen, lungs, stomach and testis of rats are the target organs of mercury, selenium and their joint poison. and liver, kidney and spleen are three most important target organs
研究結果表明,大鼠體內硒與汞的急性和亞慢性相互作用主要表現為拮抗作用;大鼠肝臟、腎臟、胸腺、心臟、脾、肺、胃和睪丸等組織器官都是硒、汞及其聯合毒物的靶器官,其中肝臟、腎臟、脾臟是三個主要靶器官;肝臟中汞與硒的含量呈高度正相關,腎臟中汞與硒的含量呈負相關,但相關性不甚好。Investigation and analysis on normal value of urine mercury in healthy residents in guangdong province
