Mix separately , then combine and mix part a : b = 3 : 2 by volume and stir well . mechanical mixing equipment is recommended 各组分搅拌均匀，再将两组分按a组分（液体） ： b组分（基料） 3 ： 2 （体积比）混合，并搅拌均匀，需使用机器搅拌。
Mix part a and part b separately and combine in the following proportions ; part a : part b = 4 : 1 by volume . mechanical mixing is recommended 各组分搅拌均匀，再将两组分按a组分： b组分4 ： 1 （体积比）混合，并搅拌均匀。推荐使用机器搅拌。
Supraconductivity - part 12 : matrix to superconductor volume ratio measurement - copper to non - copper volume ratio of nb3sn composite superconducting wires 超导性.第12部分:基体与超导体体积比的测量.铌锡复合超导金属线的铜对非铜体积之比
Tooth crowding occurs if there is inadequate room for all permanent teeth to erupt or when the permanent premolars erupt and the growth of the jawbone stablizes 牙齿排列不整齐由于恒齿的体积比乳齿大，恒齿长出时可能不够空位，引致牙齿排列参差不齐。
Two percent of hpmc appeared to be a satisfying suspending agent by evaluating the sedimentation rate and the redispersion of nabumetone 通过对其沉降体积比、再分散性指标的考察，筛选了2 % hpmc助悬剂，并从流变学、混悬剂黏度及显微形态等方面对其稳定性进行了研究。
The optimal synthetic conditions obtained was n ( dac ) : n ( am ) = 2 : 3 , v ( oil ) : v ( water ) = 1 : 1 . 2 and redox initiator or high water - soluble initiator 在单体物质的量比为2 : 3 ，油水体积比为1 : 1 . 2 ，引发剂为氧化还原引发剂或高效水溶性引发剂的条件下，得到了溶解迅速且絮凝效果好的产品。
Zinc acts as negative material of batteries , with the advantages of low equilibrium potential , good reversibility , high specific energy , rich resources , low cost , little poison and easy treatment 锌作为电池负极材料，其优点有：平衡电位低、可逆性好、质量比能量和体积比能量高，而且锌资源丰富、价格低廉、毒性小、易处理。
The first of the newly upgraded regional mobile command units were introduced . the units arelarger and incorporate many improvements to enhance the communications and control capabilities of commanders in the field 年内，警队引入首批全新改良的总区流动指挥车，车辆体积比前较大，设备更新，可让指挥官在事件现场更有效执行联络及指挥工作。
However , you should also note that the whereabouts of remote transaction managers are encapsulated in all the propagation tokens , making them bigger than the corresponding transaction cookies from the export import model 但是还应该注意，所有传播标记中都封装了远程事务管理器的行踪，使得它们的体积比“导出/导入”模型中对应的事务cookie更大。
Au radioactive tracer method . the effect of several variables such as stripping agent concentrations , the volume ratio of stripping agents to gold loaded organic phase and the continuous extraction after stripping was studied under 20 . it is found that nh 等对季铵盐载金有机相的反萃，考察了反萃剂的浓度有机相与反萃剂的体积比等对反萃率的影响。
