Abstract : based on the objectivity of space, time and their measuring, the author gives a ideal experiment of space and time measuring, educe the difference between true time and metrical time ( this difference results from the finity of light speed ), thus proves the relativity between metrical time and true time and the relativity between given reference points, gives the express formulas of relative velocity
提要:從時空及時空度量的客觀性、絕對性出發,通過具體的空間、時間測量理想實驗,導出測量時刻、時間與客觀時刻、時間的差異(這種差異的根源在於光速傳播的有限性) ,從而說明測量時刻、時間對于客觀物理量及不同參照點的相對性,給出了客觀勻速直線運動的相對速度表達式。Then, an improved genetic algorithm is proposed to solve this problem. this algorithm makes trees with the source and all destinations are the space of operation and filter operation. with hybrid selection operator, competition among brothers, greedy operation, filter operation
然後給出了一種基於遺傳演算法的實時多播路由選擇方法,並用改進的遺傳演算法進行了求解,該演算法採用包含源節點和目的節點的樹作為交叉和變異的空間的方法,通過加入混合選擇、小范圍競爭擇優的交叉變異操作,提高了全局搜索能力和收斂速度。Given the speed and volume of international air travel today, the virus could spread more rapidly, possibly reaching all continents in less than 3 months
鑒于當今國際航空旅行的速度和運載量,這一病毒的傳播將更加迅速,可能在不到3個月的時間內傳播至所有大陸。Impervious wall is thin and deep, so it cannot satisfy the hypothesis of half space. the surface wave theory of impervious wall is analyzed and proves that surface wave speed in impermeable wall is nearly equal with that in plane - strain problem, so the transverse w ave speed getting by rayleigh surface wave exploration technique can satisfy the precision desire of engineering
我們對面波在防滲墻中傳播原理進行了分析,證明防滲墻中的面波波速與半空間理論中面波波速差別很小,因此,用瞬態面波檢測技術來獲得剪切波速可以滿足工程精度的要求。分享友人
