A novel method to reduce crucible erosion is by suppressing thermal convection currents, which can be done by applying a magnetic field to the melt . 减少坩埚侵蚀的有效方法是对熔体施加磁场以抑制热对流的流动。
In the absence of successful efforts to stem the loss of topsoil, the social effects of erosion will probably first be seen in africa . 在控制表土流失的努力缺乏成效的情况下,土壤侵蚀的社会影响将可能首先出现在非洲。
Finally , the characters of the erosion are concluded 并对侵蚀的性质进行了归纳。
