Also, by providing such heat insulating layer as an oxide intermediately in a grain boundary of a compound of CoSb3 in a sintered body, the heat conductivity is reduced.

而且，通过在烧结体的CoSb3系化合物晶界中插入氧化物等绝热层，可降低导热系数。

In spite of the limited air sounding data, we would use the adiabatic lapse rate method and the time interpolation to get the hourly mixing height. It should be noticed that the degree of accuracy was not so good enough that we can completely believe it. As a result, the follow research worker should notice this over estimation by the method.

因此尽管在有限的例行气象探空观测下，采用乾绝热递减法配合时间权重内插计算是现有条件下的一权宜方法，但是须注意的是，此方法的准确性并不如我们所预期，混合层比对的相关性也不甚理想，因此建议后续研究，如有继续采用乾绝热递减法来决定混合层高度之时，应多加留意探空资料对混合层所产生的高估影响。
