The results show that the adding methods adding quantity , the sizes of adding particles heating temperature and heat preservation time have effects on the absorptivity , but the sizes of adding particles is the most important factor 研究发现，加入方法、加入量、加入的颗粒大小、加热温度和保温时间等因素均对吸收率有影响，而颗粒大小对吸收率影响最大。
If the quantity of sr is over some value ( 0 . 02 % - 0 . 04 % ) , the melt will absorb hydrogen , and result in the formation of cavities . we think the reason is that the dissociated sr destroyed the compact oxide film of the melt Sr的加入量过多( 0 . 02 0 . 04 )后，反而出现吸气现象，导致形成孔洞缺陷，我们认为这是游离态sr破坏了al - si合金的致密氧化膜所致。
Peg and pmaa - nh4 were used to disperse sic and si3n4 nano - particles in water and alcohol . the results showed that the high dispersion and stable suspension were obtained as the addition of pmaa - nh4 being 0 . 3wt % and ph value 9 ~ 10 沉降实验和粘度实验结果表明，采用pmaa - nh4作为分散剂，分散剂加入量为0 . 3wt % ， ph值为9 ~ 10时，可以得到高分散、高稳定的水悬浮液。
In addition , time delay of impact of irregular coke charge to silicon content in hot metal has been analyzed statistically . it is shown that silicon content in hot metal of 60 . 24 % tapping increases after six hours of irregular coke charging 对净焦加入量（或次数）对铁水含硅量的作用时间进行的统计分析结果表明：加入净焦6小时以后， 60 . 24 %炉次会出现炉温升高现象。
The boracic acid was used to prepare flexible graphite and the effect of amount of boracic acid addition on expanded volume , oxidation resistance , specific resistance and tensile strength of the fexible graphite obtained were analysed 摘要初步探讨了制造柔性石墨材料过程中加入添加剂硼酸的方法，并就硼酸的加入量对其膨胀倍数、抗氧化性、电阻率、抗拉强度等的影响进行了比较和分析。
These results show that the nanocomposites is toughened and strengthened . the thermal stability of nanocomposites is improved and when organic montmorillonite content is lwt % , heating distortion temperature ( hdt ) of nanocomposites increases by 17 . 6 ? from 75 . 8 ? to 97 . 4 ? 复合材料的热稳定性有所提高，且在有机蒙脱土加入量为1wt时，热变形温度比纯不饱和聚酯( 75 . 8 )高17 . 6 。
When accede to 5 % nano - clay in epoxy resins , that impact strength and distort strength of the nano - clay / epoxy composite materials were improved 303 . 2 % and 45 . 5 % , it have important meaning for enlarging application field of epoxy resins 试验结果表明，当纳米粘土加入量为5 %时，复合材料的冲击强度和弯曲强度，分别比纯环氧树脂提高303 . 2 %和45 . 5 % ，这对拓宽环氧树脂的应用领域具有重要意义。
The powder ' s structure was ss ~ r uctur e v ~ s an a 1 ~ z e d by ~ d , " em results showed that the anti - bacterial activation of ti02 could be improved by the introducing of ag ~ and the anti - bacterial properties of powder was conjuct effect of tic ) 2 and age 6 ）抗菌粉体的应用选取特定的抗菌粉体制备出抗菌陶瓷、搪瓷、聚乙烯塑料制品，测试了制品的抗菌性和其它性能，确定了抗菌粉体的最佳加入量。
The effects of la , ce and mischmetal additions , adding methods and adding amount , on the ignition temperature of zm5 mg alloy are investigated . the effect of little be addition on the ignition temperature of zm5 mg alloy with mischmetal is also investigated 考察了分别加入镧、铈和混合稀土以及不同加入方式和不同加入量对zm5镁合金起燃温度的影响，同时还考查了微量铍对含混合稀土的zm5镁合金起燃温度的影响。
( 2 ) the use level of inert solvent was important too : the volume was larger , the losing of the indicator was more severe ; the volume was smaller , the amount of pores were less ; either went against improving the sensibility of the probe 指示剂加入量过多或过少都会使响应灵敏度降低；交联剂、致孔剂量的改变均不影响光纤的疏水性。因此本实验选择最佳的交联度为70 ，致孔剂量为0 . 05ml ，指示齐加入量为5 . 0 10 ~ ( - 8 ) mol 。
