The instability in the natural convection boundary layer initiates with the buoyancy eigenmode and develops into non - linear stage with the turbulization of the buoyancy eigenmode. in the mean time, the invisid eigenmode at the inflexion point appears and begins to increase at the outer layer. experimental results show that the turbulent layer near the maximum velocity point can be detected while the reformed grashof number
自然對流邊界層的穩定性由浮力振型失穩開始，並隨著浮力振型的湍流化進入非線性階段，與此同時，無粘性振型在外層開始失穩。實驗結果表明，修正格拉斯霍夫數grashof -
Compared to the basins in east guangxi, the basin of north guangxi is characterized by lower depositional and tectonic subsidence rate during rifting, longer thermal subsidence, later inflexion point from rifting to foreland buckling, as well as later inflexion point separating stable stage from active stage during foreland - buckling
但與桂東大瑤山地區相比，桂北興安地區在裂陷階段的沉積速率和構造沉降速率明顯偏低；熱沉降階段的持續時間偏長；裂陷階段與前陸撓曲階段的分界拐點偏晚；前陸撓曲階段，由構造寧靜期的緩慢沉降向構造活動期的快速沉降轉化的分界拐點也偏晚。 -
And then, a segment feature extract algorithm based on etab ( sfe _ etab ) is proposed. the basic idear of this algorithm is to find the inflexion, end point and broken point in the thinned image by utilizing the specialty of which complicated segements naturally disassemble basic segements after etab thinned a character primarily. after that, it joins the segments to get the beeline corresponding to each segement
在上述研究的基礎上，提出了一種基於邊界細化的筆段提取演算法，演算法的基本思想是利用基於字元邊界細化演算法初步細化后字元中部分復雜筆劃已分解成筆段的特點，找出細化圖像中的拐點、端點、斷點;然後利用原圖的連通關系把斷開的基本筆段進行合併;最後進行筆段的提取。
