feeding channel meaning in Chinese

补给通道
供应孔道

The research showed that basin is the more important feeding resource than runner in runner type gating system in lost wax casting . therefore , on the basis of the basin as feeding resource , runner and ingate as feeding channel , a new design method for runner type pouring and feeding system in investment casting was developed . the corresponding feeding mathematical pattern and allowable total weight listed for casting cluster with different basin were established after analyzing the practical feeding of basin and the calculating process for design was described in detail
在熔模铸造横浇道型浇注系统中，浇口杯是比横浇道更为重要的补缩源，因此在立足于浇口杯为补缩源、横浇道和内浇道为浇注补缩通道的基础上，开发了适用于熔模铸造横浇道型浇注补缩系统设计的新设计方法，在详细分析了浇口杯的实际补缩情况后，建立了相应的数学补缩模式和不同浇口杯的铸件组许用铸件总质量表，并具体介绍了设计计算过程。
