Numerical examples show this mesh - less method is simple and effective 數(shù)值算列表明該方法是簡(jiǎn)單、有效的。
A point interpolation method developed in recent years is one of the new kind of mesh - less method 點(diǎn)插值方法是近年來(lái)發(fā)展起來(lái)的一種新型無(wú)網(wǎng)格方法。
It is a new truly mesh - less method , because the background cells for integration are not needed . it uses the weighted function of gaussian or of spline as a test function of the weighted residual method 這種方法采用高斯權(quán)函數(shù)或樣條函數(shù)作為加權(quán)函數(shù);同時(shí)這種方法只包含中心在所考慮點(diǎn)處的規(guī)則局部區(qū)域上以及局部邊界上的積分;所得系數(shù)矩陣是一個(gè)帶狀稀疏矩陣。
The present situation of energy utilizing in foundry industry was analyzed , the main effective energy saving techniques and their application was described in aspects of melting and heating systems , moulding and core - making processes and equipments , low - stress cast irons , as - cast nodular irons , feeder - less method of nodular reclaiming of cupola gas , and so on 摘要分析了鑄造行業(yè)能源利用現(xiàn)狀,從熔煉加熱系統(tǒng)、造型制芯技術(shù)與裝備、低應(yīng)力鑄鐵、鑄態(tài)球墨鑄鐵、球鐵無(wú)冒口鑄造、鑄鋼保溫冒口與保溫補(bǔ)貼、沖天爐廢氣綜合利用和余熱回收利用等方面闡述了鑄造行業(yè)行之有效的主要節(jié)能技術(shù)及其應(yīng)用。
