费约果压条繁殖生根率高，但其繁殖系数较低，对母树树体损伤严重，且根系不发达，生产上一般也不采用。

Layering had a high rooting rate, but its propagation coefficient was lower and would injure the mother tree, the roots are also underdeveloped.

另外，将不可压的速度场从旧网格更新到新网格上，仍然要满足不可压条件是比较困难的。

And to update the velocity to the new mesh efficiently but still divergence free is still a problem.

在试验研究的基础上，建立了预测高温高压条件流变参数的回归模型。该回归模型可用来预测限定条件下某一井深处的流变参数。

Based on the tests, the regression equations were achieved, which can be used to predict the rheological behavior of LPBM under downhole conditions.
