For successful casting operations, once a grid alloy has proven satisfactory, it is important that the specified tolerance be held within the limits . 为使铸造操作顺利进行,一旦证实板栅合金适于铸造,保持规定的容差在限度范围内是很重要的。
This alloy is a bit tricky as it sometimes may harden in the first twenty four hours after casting, becoming almost brittle, and produce cracks in the grid frames, etc . 这种合金制造有些棘手,因为有时铸造后24小时内硬化,几乎变得很脆,在板栅框等处产生裂痕。
They debase the polished and current language of books, by the vile alloy of provincial idioms, and colloquial barbarism, the shame of grammar, making it akin to any language, rather than english . 他们公然想使文学沦为俗流,用乱七八糟的方言、粗野的土话、难登大雅之堂的文法以败坏现今出版物中典雅的文字,使之不伦不类,就是不像英文。
