When hardwood cutting, it could improve the survival rate to eighty-five percentage by using cuttage stored in sand, frame culture and vermiculite.

在硬枝扦插时，采用插条冬季沙藏、早春温床催根、以保温性好的蛭石做扦插基质等措施能使扦插成活率提高到85%；

On the basis of acoustic impedance inversion, sand percentage section and sandstone porosity section are made using time average equation and interpolation formula. These two sections are significant to the extrapolation of logging data under ideal condition.

在波阻抗反演的基础上，利用时间平均方程和内插公式做了砂岩百分含量剖面和孔隙度剖面，这两种剖面在比较理想的条件下，对测井信息的外推有重要参考意义。

In the trial range, the effect of sand percentage and coarse aggregate gradation on the strength of concrete is not significant. And they could be certained by the pumpability and other technical indicators.

在试验选定的研究范围内，砂率和粗骨料级配则对混凝土的强度影响不显著，可根据混凝土可泵性等其它技术指标确定其合理取值范围。
