  1. Abstract : this paper, by analyzing the effect of differences of mineral structure of 2 1 layer minerals, the properties of their interlayer charge and changes of some properties caused by weathering on the attractive force for interlayer cation, reached the conclusion that : the fixation capacity is determined by the ratio of the total amount of interlayer charge and that of tetrahedral charges. the relationship of interlayer cation fixation and octahedral structure of secondary minerals is probably different from that of primary minerals. the oxidation and reduction of variable valence cations can greatly influence the cation fixation capacity

    文摘:分析2 1型礦物的結構差異、層間電荷性質以及在風化過程中某些性質的變化對層間陽離子吸引力的影響，對已有報道中一些矛盾的結果或不具普遍意義的結論進行了討論.得出幾個較為明確的結論：層間總電荷與四面體電荷所佔比例大小共同決定礦物對層間陽離子的固定能力；原生礦物中八面體結構與層間陽離子固定間的關系對次生礦物而言，也許並不一致；八面體中可變價陽離子的氧化還原，可導致礦物固定陽離子能力發生較大變化
  2. Considering when most of different atoms combine together, the covalent bond and the electrovalent bond are concomitant

    考慮到大多數異類原子結合是採取共價結合與離子結合之間的過渡形式。
  3. By home analyzing the experiment result, we think that the covalent bond is more than the electrovalent bond in y - fe _ ( 2 ) o _ ( 3 ) crystallites. it is the dominating reason that the dependence of y - fe _ ( 2 ) o _ ( 3 ) crystallites grin size on lattice constant is differ from one of the ionic crystallites

    通過對實驗結果的進一步分析，我們認為其主要原因是在丫一fezo3中原子之間結合的共價性超過了離子性，因而導致了它們的晶格常數隨晶粒線度的變化趨勢和離子晶體正好相反。
  4. The results of lauryl sodium sulfate - polyacrylamide gel electrophoreses ( sds - page ) of the aggregate precipitate and supernatant and the result of high - performance size - exclusion chromatography of the supernatant indicated that, by wrongly linked intermolecular disulfide bonds soluble bi - molecular and tri - molecular egg white lysozyme aggregate could be simultaneously formed except being renatured to native and active egg white lysozymes during the refolding procedure of denatured - reduced egg white lysozyme ; the aggregate precipitate could be further formed by the non - covalent bonds interaction between the soluble hi - molecular egg white lysozyme aggregates, and the soluble tri - molecular egg white lysozyme aggregate could still stay at the supernatant

    沉澱和上清液的不連續十二烷基硫酸鈉聚丙烯酰胺凝膠電泳（ sds - page ）和高效凝膠排阻層析分析結果表明，還原脲變性蛋白溶菌酶在稀釋復性過程中除了能夠復性成天然態蛋白溶菌酶分子外，還會形成可溶的蛋白溶菌酶分子二聚體和三聚體，二聚體和三聚體主要是靠分子間二硫鍵的錯配連接而成的；可溶的蛋白溶菌酶分子二聚體之間通過非共價鍵相互作用而形成集聚體沉澱，而可溶的三聚體溶菌酶分子則仍處于復性液上清液中。
  5. Finally, the distribution discipline of the cyclic changing temperature damage factor under the conditions of low temperature through the equivalent assumption and energy equivalent model based on damage mechanics theory. the fatigue life of the 4cm depth sawed cracking road is obtained under the conditions of - 15 based on the shenyang - dalian highway. in this paper, the inhomogeniety of asphalt concrete resulting from temperature change is considered, when the influence of the temperature change on the semi - rigid asphalt pavement concrete is analyzed

    最後，基於損傷力學理論，通過等效應變假設原理和能量等價模型，得到低溫下循環變溫損傷因子的分佈規律，以沈陽?大連高速公路的預鋸縫為工浙江大學博士學位論文廣義荷載作用下道路與軟基共同作用研究王金昌2003年5月程背景，預測了4cm深的鋸縫在一巧路表變溫作用下的疲勞壽命。
  6. Such methods are generally decreasing method, such as, feasible direction methods, constrained variable metric methods, etc. another class is sub - problems method, which approximates the optimal solution by solving a series of simple sub - problems, such as penalty function methods, trust region methods, and successive quadratic programming sub - problems, etc. the same property of two classes of methods is that they determine whether the next iterative point is " good " or " bad " by comparing the objective function value or merit function value at the current point and next iterative point

    另一類叫做子問題演算法，這種演算法是通過一系列簡單子問題的解來逼近原問題的最優解，如罰函數法、信賴域演算法、逐步二次規劃演算法等。這兩類演算法的一個共同特點是，通過比較當前點和下一個迭代點的目標函數值或評價函數值來確定迭代點的「優」或「劣」 ，若迭代點比當前點「優」則該迭代點可以被接受，否則須繼續搜索或調整子問題。
