The sixth section gives the experimental results in the quasi - steady flow around the caudal fin and mimic the forward swimming using the caudal fin as the propulsor. and then review the speed and track of the robotic fish swimming when locomotion parameters are set in the experiment condition
第六部分通過機器魚的自主游動實驗，初步模擬了機器魚利用尾鰭擺動推進前進，考察了實驗條件下設定魚的尾鰭擺動相關參數的情況下魚的游動速度和尾鰭的擺動軌跡情況。Based on experimental result of energy dissipation and scour protection for downstream of spillway at yu jian kou power station, this paper discusses the flow characteristics, aerated characteristics of flaring gate pier for low dam pivot, the influence on pressure of dam surface and the result of energy dissipation for flaring gate pier. it is put forward to be an available method to solve the problems of energy dissipation and scour protection for depth of covering strata, poor geologic condition and weakness of resistance to scour capability under reasonable use of flaring gate piers and auxiliary dissipaters. thus, a new method is obtained for release of floodwater and energy dissipation of low dam pivot which are provided with low water head, great unit discharge and low froud coefficient. it may be used for reference for design and test workers
結合魚劍口電站壩下消能防沖試驗研究成果，對低壩樞紐寬尾墩的水流特點、摻氣特性、寬尾墩對大壩泄流能力和壩面壓力的影響以及寬尾墩的消能效果等問題進行了初步探討，提出了合理地使用寬尾墩結合輔助消能設施可有效地解決壩下覆蓋層深，地質條件差，抗沖能力弱的低壩樞紐的消能防沖問題，從而為具有低水頭，大單寬流量，低佛氏數特點的低壩樞紐泄洪消能開辟了一條新途徑，可供有關低壩樞紐設計與試驗工作者借鑒與參考The results showed that pcr applify a 485 specific molecular band in 672 individuals, the rate of positive reaction is 60 %, southern blot result shows a strong signal in transgenic fish. it is concluded that hu - - ifn gene has been integrated and expression. it is also that foreign gene integrating position and copy number is different individuals, by elis a detecting, 23. 5 % transgenic fish " were detected hu - - ifn gene expression in all 672 transgenic fish, but expression level of hu - - dfn is significant difference in different individuals and growth period
2000年共顯微注射32197粒草魚受精卵，出苗12945尾草魚魚苗，經孵化培育最後獲得1120尾五寸左右草魚，對1120尾草魚提取血液總dna進行pcr和southern雜交檢測， 2000年轉導的草魚的pcr檢測結果，有672尾草魚即600k轉化個體的總dna能擴增出一條485kb的特異分子帶，說明轉化個體整合有huj ifn基因，經southern雜交進一步證實，轉入的抗病相關基因己在轉基因草魚體內染色體上得以整合，但整合位點沒有固定區域，整合的拷貝數存在較大差異。In the solution, the 0 - 1 integer and real number mixed encoding technique was employed to describe an artificial fish ; behaviors of a fish were dispatched by its body energy status ; the following behavior was described by the greedy method where moving step is direct ratio to a fish ' s hungry degree ; the lowest survival body energy controlling technique was used to realize escaping policy from locally optimum positions ; the maximum iterating times and the changing degree of the optimum solutions during iterating were used to control the terminating time
在解算過程中，人工魚個體採用0 - 1整數和實數混合編碼方法描述；用人工魚體能累計和消耗程度來調度其行為；採用與饑餓程度成正比的移動步距的貪婪法描述個體追尾行為；採用最低生存體能控制來實現局部最優解逃逸策略；採用最大迭代次數和迭代過程中最優解平均值變化程度來控制迭代終止時機。Abstract : based on experimental result of energy dissipation and scour protection for downstream of spillway at yu jian kou power station, this paper discusses the flow characteristics, aerated characteristics of flaring gate pier for low dam pivot, the influence on pressure of dam surface and the result of energy dissipation for flaring gate pier. it is put forward to be an available method to solve the problems of energy dissipation and scour protection for depth of covering strata, poor geologic condition and weakness of resistance to scour capability under reasonable use of flaring gate piers and auxiliary dissipaters. thus, a new method is obtained for release of floodwater and energy dissipation of low dam pivot which are provided with low water head, great unit discharge and low froud coefficient. it may be used for reference for design and test workers
