得出如下的結論：珠江水體hco _ 3 ~ -離子含量在一個水文年中發生顯著變化，特別是豐水期與枯水期之間波動幅度較大；無機碳含量西江含量最高，其次是北江，東江最低；西江無機碳主要來源於巖溶作用，由於受河流沖刷效應影響，豐水期hco _ 3 ~ -離子含量升高；東江流域無機碳主要來源於硅酸鹽巖的碳酸鹽風化過程，豐水期hco _ 3 ~ -離子含量無顯著變化；北江無機碳來源於巖溶作用和硅酸鹽巖的碳酸鹽風化過程，受稀釋效應影響，無機碳含量隨水量增加而降低。Many studies had attempted to characterize chemical weathering process by focusing on geochemisty of river particulate and sediment. the sediment geochemistry may reflect and compare with the carbonates and silicates weathering degree by introducing the chemical index of alteration ( cia ) and new sediment index of variation ( siv ) and elemental molar abundance ratio of the sediment. the one main objective of this study would provide and compare the relative weathering intensities of silicates and carbonates with the different basins
2沉積物地球化學與化學風化進程和機械剝蝕率化學風化指數與化學風化率屬于表徵化學風化作用意義不同的函數，前者為相對概念反映流域巖石在原巖基礎上己發生淋溶作用的深度，主要受到了氣候因子的深刻影響（中國流域沉積物化學風化指數由北到南呈有規則的遞增序列，氣候因子對風化進程的影響掩蓋了巖性的巨大差異） ，而化學風化率含義是指單位流域面積巖石風化淋溶產生的離子絕對總量。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。In young chickens aev induces paralysis, ataxia and muscular dystrophy, while in older chickens, infection is usually subclinical, resulting in a decline in egg production and hatchability. infectivity was shown to remain unaffected by chloroform, low ph, pepsin, trypsin and deoxyribonuclease. magnesium cations were shown to stabilise preparations of the virus against heat inactivation. the buoyant density of virions are 1. 31g / ml. the diameter of the virion was estimated to be 22 to 30nm. the aev can be adapted to grow in chicken embryo. the inability of aev to grow effeciently in most cell cultures
幼雞感染該病毒后，引起麻痹、頭頸震顫甚至共濟失調，而成雞常呈亞臨床感染或導致產蛋量和孵化率下降。病毒的感染性不受氯仿、低ph 、胃蛋白酶、胰酶和脫氧核糖核酸酶的影響，鎂離子可增強病毒對熱的穩定性，病毒的浮密度為1 . 31g ml ，直徑為22 - 30nm ，該病毒主要在雞胚中增殖，在大多數細胞培養物中不生長。But on the later condition the trend of accumulation turned to be stable in the w3 treatment ( vseawater / v pure water = 1 ) - in root zone soil, variation of sar value accorded with total salt accumulations and sometimes decreased at the treatment where the v seawater / v pure water > 1. contents of cl - and na + which were the main ions and leached obviously in 0 - 60cm soil were greatly influenced by rainfall, but the rainfall did not affected the contents of ca2 +, mg2 + and k + whose ability of leaching is worse than that of cl - and na + in the root zone soil obviously. the vertical distribution of salt ions in the 0 - 60cm soil were mainly affected by the ratio of v seawater / v pure water in the irrigation water on the condition of not enough rainfall, but on the cont
海水灌溉下，耕層土壤中鹽分含量受降雨量影響很大，足夠的降雨條件下，鹽分不會積累，降雨量較低時，鹽分積累明顯，但在50海水處理下趨于平衡狀態；耕層土壤sar值的變化情況和鹽分含量變化情況相一致，在灌溉水中海水濃度大於50時有所下降；土壤中主要鹽離子為cl ~ -和na ~ + ， 0 - 60cm土層內， na ~ + 、 cl ~ -明顯的向土壤底層遷移，其在土壤中的含量受降雨影響顯著，而ca ~ （ 2 + ） 、 mg ~ （ 2 + ）和k ~ +在土壤中遷移能力較低，其含量受降雨影響較小； 0 - 60cm層次土壤鹽分的縱向分佈在降雨量較低的條件下主要受灌溉水中海水濃度的影響，而在降雨充分的條件下，地面覆蓋程度成為重要的影響鹽分和水分脅迫下菊芋的生理響應及其海水灌溉研究因子之一。Some trends in the studies of cellular inorganic chemistry have been described in this review, which mainly contains the aspects of effects of metal ions including calcium ions and lanthanide ions and activated small molecule on ion channels, receptor proteins in the membrane, intracellular receptor proteins and cellular function

在離子束介導外源全dna轉化中，外源全dna包含有供體的所有遺傳信息，這些外源片段對受體的影響是多方面的，因此轉化效果無法用統一的轉化率來衡量，這就給最佳轉化條件（主要是轉化劑量）的選擇帶來了很大的困難。The results show that v5 + whose valence changes is an acceptor impurity and after heat treatment especially at 655. the phenomenon is consistent with the result of the dta ( differential thermal analysis ). the result of dta indicates that v2o5 has a phase transformation absorption peak at 655 while the signal of esr of low valence of v ion is the strongest
