Yes, materials with better lofting effects fill the same space at a lighter weight, in other words, with the same amount of materials, you can fill more cans.

是的，具有较好乐浮效果的材料可用较轻的重量填充同一空间，换句话说，用同样量的材料，你可以填充更多的排气管子。

Fiberglas-Magnesia board is also called magnesia board, which is made of magnesia, magnesium -chloride and water.

The results show that the polymer determines the electricity conducting of coal filled polymer composites. The coal filled PP composites is an insulating material, and be independent of coal type, its direct current resistivity is above 10〓Ω·cm. The resistivity drops with the content of coal when using anthracite, but it is also above 10〓Ω·cm, and the surface modification of coal, especially alkylated, resumes the insulance of composites.

X射线衍射测试表明即使在高变质程度下煤中的石墨晶区含量仍较低，煤填充聚合物复合材料电性能主要由基体材料性能决定，通过动电容静电计对煤填充聚丙烯复合材料直流电导性研究表明，煤填充聚丙烯复合材料是绝缘材料，其绝缘电阻在10〓Ω·cm以上，在高含量情况下，仍能保持良好的绝缘性，而与煤种无关。

As far as the φ 30 mm ×300 mm column apparatus is concerned, the better applying is that filling length exceeds 20 cm; contacting time is beyond 0.5 h and outflux is 2.7 mL/s.

随着填充高度的升高、处理液与抗菌材料接触时间的延长、处理液出口端流量的减小，填充柱的杀菌性能逐渐升高；对于声30mm 300mm的填充柱，当填充高度≥20cm，停留时间≥0.5h，出口端流量为2.7mL／s时，杀菌效果较好。

The resistivity of filled skutterudites increases with the increase of the filling fraction. It originated from the decrease of carrier concentration in the skutterudite for the samples with high filling fraction and also the difference of the content of Fe Sb〓 and Sb in the samples.

填充型方钴矿材料的电阻率随填充率的提高而增大，这一方面是因为镧的引入使材料的载流子浓度降低，另一方面低填充率的样品中的低电阻率还与样品中的FeSb〓和Sb杂质的存在有关。

The low-temperature resistivity of filling skutterudite increases with the increase of temperature. However the slope of the resistivitytemperature curves are different. The curve of the sample with low filling fraction is smooth, and that of the samples with high filling fraction is sharp. It is caused by the existence of the impurities in the samples with low filling fraction.

填充型方钴矿材料的低温电阻率随镧填充率的变化规律与室温相同，但不同填充率的方钴矿材料的电阻率随温度变化的曲线的斜率不同，低填充率样品随温度变化趋势明显地比高填充率样品平缓，这种现象主要是由存在于低填充率样品中的杂质相引起的。

The results of XRD indicated that the addition of lanthanum in skutterudite could enhance the formation of skutterudite during the synthesis process. The content of skutterudite increases with the increase of the filling fraction in 〓. The lattice parameter of filled skutterudite increases with the increase of lanthanum filling fraction. It is caused by the deformation of Sb〓 ring arising from the "rattling"of the filling atoms in the voids in skutterudite.

对不同填充率方钴矿La〓Fe〓CoSb〓材料的XRD研究发现，镧元素的引入可以促进方钴矿相的合成，相同条件下合成的方钴矿的纯度随镧填充率的增大而提高，材料的晶胞参数随镧填充率的提高而增大，这是填充原子在方钴矿晶体的的孔隙内震颤和晶胞内Sb〓四边形发生扭曲变形所致。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
