Engineering Practice shows that the coefficient of heat conduction small insulation of the fine, construction performance, stable, non-toxic and non-radioactive pollution characteristics.

工程实践表明，其具有导热系数小，绝热性优良、施工性能稳定、无毒无放射性污染等特点。

Finally, the fluid flow of the weld pool was taken into account by increasing the heat conduction coefficient at elevated temperature.

最后采用增大热传导系数的方法，考虑了熔池内流体流动对整个温度场的影响。

Bulk density of small materials, heat conduction tear your eyes coefficient is generally small, but at the same time decreases in the mechanical strength, so be reasonable choice.

容重小的材料，一般导热泪盈眶系数也小，但同时机械强度也随之降低，故要合理选择。
