  1. If the sepals are joined at their lateral margins a calyx tube is formed, the mouth of which may be extended into lobes or teeth

    有的花萼的一邊生出短小的管狀突起,稱為距,它可以延伸進入其他的結構。
  2. The numerical simulation of axisymmetric two - dimensional shock tube is studied, which has a conical convergent section, and its driving gas is the hot product of hydrogen oxygen detonation. finite volume tvd scheme is adopted and the mesh is local orthogonal. the primitive equations are euler s equations of multi - component flow. the new method of eliminating numerical oscillation at the interface of two materials is extended to two dimensions. the mechanical character of this shock tube is analyzed

    對由前向爆轟產生驅動氣體並具有局部錐形收縮截面的軸對稱激波管利用兩相常比熱完全氣體的歐拉方程組和有限體積tvd格式在局部正交的網格上進行了二維數值模擬。將消除兩種介質界面處數值振蕩的新方法成功地推廣到二維情況。分析了該激波管的力學特性。
  3. Compares the 3 - d ift with smooth tube, the result shows that heat transfer augments, volume decreases, metallic material reduces and energy saves. so the tube with three dimensional internally extended surface have very wide engineering application background

    使用結果表明:使用了三維內肋管的換熱器同未使用前相比,換熱強度提高,體積減少,金屬材料耗量減小,能耗降低,具有十分廣闊的應用前景。
