研究结果表明，在未经有机化处理的情况下，纳米碳管以纳米结构状态分散在基体中，显著地提高了聚醚酮酮的耐热性能，降低了其熔点。

The experimental results show that CNTs dispersed in matrix in the scale of nanometer without chemical processing, then thermal property of PEKK was improved obviously and its melting point reduced.

把镓装在一个塑料管中，做成螺旋蜷线形式，一边提高温度到镓的熔点之上，于是在这螺旋蜷线上就有许多个熔区。

By means of this method it provides multiple zone on one side of the helix of plastic tubing in which the material to be refine1 is filled.
