However the unpurified bio-oil contains many oxygenic compounds leading to the high oxygen content of bio-crude ( 40wt % ) which lead to some detrimental properties such as low heating value chemical instability and immiscibility with hydrocarbon fuels and so on .

然而， 未 精制的生物油中含有大量的含氧化合物，其中的氧含量高达40%，导致生物油热值低、化学稳定性差、不互溶性等缺点。

Using α _6-integrin as the cell marker the positive rate of the unpurified group was 2.38 % ± 0.60 % significantly lower than that of the purified group ( 72.04 % ± 3.65 % P < 0.01 ) .

以α6-整合素作为细胞标记， 未 纯化组的阳性表达率为2·38%±0·60%，纯化组为72· 04%±3·65%，两组差异非常显著（P<0·01）。

High purity flake silver powers which are mainly used as electric paste in electric industry can be manufactured by the novel method using unpurified silver as raw material .

以 未经 电解 的 粗银为原料，氧化银和银 氨 溶液为 中间 产物，用 甲醛为还原剂，采用行星式球磨方式可以制备高纯度片状银粉。

The purified BCE resin had lower content of impurity such as residual bisphenol A than the unpurified and thus leads to higher cure reaction temperature and better heat resistant properties of the resin cast .

提纯将降低 BCE树脂中的双酚A等杂质的含量，提高固化反应温度，提高树脂固化 物耐热性。
