效率

This is the cause of enhancement of extraction of dihydromyricetin from Ampelopsis grossedntata by microwave.

这就是微波辅助提取植物胞内有效成分的提取效率大为提高的原故。

Results Amplification efficiencies of 4 standards are 0.80, 0.80, 0.84 and 0.85, respectively.

结果 4个标准的扩增效率分别为0.80，0.80，0.84和0.85。

So it is worth to design an audio power amplifier with the features of high power and high efficiency.

因此，设计一种失真度小，输出功率大，效率高的音频功放也有很重要的现实意义。

If the cell density of Anabaena flos-aqua and Microcystis aeruginosa was 6×10-7×10^9 cellsl^(-1) and 4×10-5×10^8 cellsl^(-1), the FDA staining rate would be more than 94% and 91%.

对细胞密度为6×10^7-7×10^9个l^(-1)的铜绿微囊藻，FDA染色效率可达94%以上。

If the cell density of Microcystis aeruginosa and Anabaena flos-aquae was 6×10~7~7xl0~9L~-1 and 4 × l0~7~5×l0~8 L~-1, the FDA staining rate would be more than 94% and 91%.

对细胞密度6×10~7～7×10~9L~(-1)的铜绿微囊藻，FDA染色效率可达94%以上。

But if the cell density of Anabaena flos-aquae increased to 5×10^9 cellsl^(-1), the staining rate would fall to 67% obviously due to cell twisting together.

对细胞密度为4×10^7-5×10^8个l^(-1)的水华鱼腥藻，FDA染色效率可达91%以上，但细胞密度增大到5×10^9个l^(-1)时，由於藻丝体易卷曲在一起，FDA染色率下降到67%。

But if the cell density of Anabaena flos-aquae increased to 5×10~9L~-1, the staining rate would fall to 67% obviously due to cell twisting together.

对细胞密度4×10~7～5×10~8 L~(-1)的水华鱼腥藻，FDA染色效率可达91%以上，但细胞密度增大到5×10~9L~(-1)时，由于细胞易卷曲在一起，FDA染色率下降到67%。

The onset of analgesic action in most of patients was 3 d and maintained for 28 d.

对活动能力改差善的总有效率和显效率分别为58.3%和29.2%。

Deriving calculation method of allocation efficiency of labor force resources from index increment analytic method is the gravity of the paper.

以指数的增量分析法推导劳动力资源配置效率的计算方法，是本文的重心所在。

Based on regulation study, this paper adopts case analysis to establish tax cost and efficiency evaluation index system, and designs index weight with analytic hierarchy process, so that the evaluation index is more scientific and the evaluation result is more impersonal and effective; secondly, innovation in index design.

本文在规范性研究的基础上，采用案例分析，建立税收成本与税收效率的评估指标体系，用层次分析法设计指标的权重，使得评价指标更科学合理，评价结果更客观有效；二、指标设计创新。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
