放射金

The unfold blank of the complex shape is researched by the method of emit-projection based on sheet neutrosphere.

在板料的中性上,用放射投影法对复杂钣金固定梁的形状进行展开尺寸研究。

Experimental results showed that double coats of carbon and gold on the conductive coating of radiolarite should be used.

次试验，认为放射虫化石的面导电处理应采用碳-金双法。
