实验研究对于其它铸造工艺条件下二次非金属买物的控制亦有一定的参考价值。
This experiment also has reference value to the control of secondary inclusion in other casting process conditions.
优先采用砂型铸造，主要原因是砂型铸造较之其它铸造方法成本低、生产工艺简单、生产周期短。
Give priority to the mold casting, the main reason is the casting mould casting method than other low cost, simple production technology, production cycle is short.
它们除了是“钱”以外没有任何其它意义：仅2008年一年纳税人为此支付的成本费用就达到8亿4800万美元，其中超过2/3的花费用于铸造硬币上，铸币生产过程中要消耗14823吨的锌、23879吨的铜、2514吨的镍。
And that ain't money for nothing: The cost to taxpayers in 2008 alone was $848 million, more than two-thirds of which was spent minting coins that many people regard as a nuisance.
形式和尺寸也可以通过其它一些可选工艺来达到，比如热挤出或冷挤出加工，沙模铸造，拉模铸造，或精密铸造。
Form and dimension may also be achieved by a number of alternative processes such as hot or cold extrusion, sand casting, die casting, and precision casting.
上述情况可能由于NGC无法控制的铸造工艺或其它自然条件引起。
Such conditions may be due to the minting process or other natural conditions over which NGC has no control.
为高速风扇叶轮及其它类似铸件的低压铸造模具的成功制造奠定了一定的基础。
It sets up a given basis of successful manufacturing of low pressure casting dies of impeller of high-speed fan and other casts like it.
