求翻译：摘要：铸造缺陷种类繁多，产生缺陷的原因也十分复杂。它不仅与铸型工艺有关，而且还与铸造合金的性质、合金的熔炼、造型材料的性能等一系列因素有关。因此，分析铸件缺陷产生的原因时，要从具体情况出发，根据缺陷的特征、位置、采用的工艺和所用型砂等因素，进行综合分析，然后采取相应的技术措施，防止和消除缺陷。是什么意思？

Abstract: The wide range of casting defects, defects of the reasons are very complex. It is not only related with the casting process, but also with the nature of the cast alloy, alloy melting, molding materials, performance and a series of factors. Therefore, the analysis of the causes of casting d

Summary: casting defects arising from defects, and a large variety of reasons also 10 complex. It not only for the casting chambers craft but also with the nature, alloy casting alloy smelleding, and shapes of a series of factors such as performance of materials. Thus, the analysis of causes when ca

Abstract: The casting defect type is many, has the flaw reason extremely to be also complex.Not only it with cast craft related, moreover also with the casting alloy nature, the alloy smelting, the modelling material performance and so on a series of factors concerns.Therefore%

Abstract: the wide range of casting defects, defects cause is also very complex. It not only related to the casting process, but also with casting alloys, alloy melting, molding materials related to the performance of a number of factors, such as. Thus, when analyzing the causes of casting defects,
