电热线

对普通塑料大棚内加设中棚、小棚，再覆盖无纺布被、地膜以及用电热线加热等不同处理，沉淀了棚内冬季的温度动态变化规律。

Tests were conducted on temperature variation pattern in winter in the standard plastic greenhouse under different treatment using inner plastic greenhouse , tunnel , heat preservation cover material , plastic mulch and heating wire .

电热线可以像画笔那样运用自如，将塑料切割成随心所欲的形状。

Wielded as flexibly as a brush , the wire cuts through the plastic to make any shape desired .

再者，本实用新型利用电热线的热能，以加速使得红外线磁石散发红外线。

Besides , the vehicle seat with heating function takes advantage of heat energy of the electric heating layer so as to accelerate the infrared emission of the infrared magnets .

对目前温室常用的几种供热方式如热水供热方式、热风供热方式、电热线地下采暖等作了简要介绍。

The existing greenhouse heating ways , such as heating by hot water , hot wind , and heating the plant earth by electrothermal wire and so on , are briefly introduced .
