We found that tio2 thin films are a amorphism when they are not annealed ; they are anatase when annealed at 300 c ; rutile occured be anneled at 700 ; ti02 thin films are transformed into rutile completely when be anneled at 1100. oxygen - sensing properties of tio2 thin films were analysised, and we found the variation law of sensitivity with the partial pressure of o2 and temperatures. sensitivity increases with po2 / ( po2 + pn2 ) at a constant temperature. the higher working temperature is, the slower sensitivity increasing with po2 / ( po2 + pn2 ) is
對tio _ 2薄膜氧敏器件特性進行了分析，發現靈敏度隨工作溫度和氧分壓變化的規律， 400以上時，在一定工作溫度下，隨氧分壓的增加，靈敏度逐漸升高；工作溫度越高，隨p _ （ o _ 2 ） （ p _ （ o _ 2 ） + p _ （ n _ 2 ） ）的增加，靈敏度增加越緩慢，在400下靈敏度隨氧分壓增加最快；在我們所測試的工作溫度點中， 400時具有最高的靈敏度，相對於他人的工作此溫度是比較低的。 -

As analyzed, ( 1 ) the rapd technique is highly sensitive to investigating genetic diversity in t. lepturus and e. muticus. t. lepturus exhibits lower polymorphism and genetic diversity than e. muticus ; ( 2 ) according to the analysis of the partial mitochondrial 16s rrna gene sequences, a very low intraspecific variation and considerably high divergence among species were found, which reveals a dual nature of conservatism and variability in mitochondrial 16s rrna gene ; ( 3 ) five primers generate the species - speeific rapd sites and these sites can be served as the molecular markers for species identification and ( 4 ) it can be proved at dna variation level that t. lepturus and e. muticus are of two species respectively pertainiag to different genera, which supported the nelson taxonomic conclusion

Finally, genetic optimization research is summarized on several typical production scheduling problems. after expounding the general idea of genetic algorithm, the comparative advantages in contrast to the traditional algorithm, the basic characteristics of genetic algorithm and its theoretical base, the paper puts emphasis on the efficiency of genetic algorithm in the scheduling of flow shop, and puts forward an improving genetic algorithm : the ordinal genetic algorithm based on the heuristic rules. the new algorithm introduces into the initial group the solution of heuristic algorithm, and in the group structure adopts a strategy of first ordering according to the priority of the adaptive solution, and then defining a new way of choosing probability by segments, which provides more hybridizing opportunity for optimized individuals, and designs variation - control rule to prevent single population and partial optimal solution
在論述了遺傳演算法的思想、與傳統搜索演算法的比較優勢、遺傳演算法的基本特徵和遺傳演算法的理論基礎（包括模式定理、隱含并行性、基因塊假設、欺騙問題和收斂性定理）后，重點探討了遺傳演算法在flowshop調度問題中的潛力和有效性；結合啟發式規則，提出了一個改進的遺傳演算法?基於啟發式規則的有序遺傳演算法，新演算法在初始種群中引入了啟發式演算法的解，在種群結構上採用了先按適應值優劣排序再分段確定選擇概率的新策略，使優質個體有更多的雜交機會，在變異中設計了變異控制規則，以防種群單一化，而陷入局部優化解。 -
Because the questions of partial differential equations make green function method studied difficultly for student, the variation of parameters formula and ordinary differential equation are put forward. initial value of ordinary differential equation and the boundary value of ordinary differential equation are discussed. green function with time and green function without time are introduced and theirs equations and conditions are calculated
