The rules allow countries to retaliate by restricting imports of subsidized or dumped goods, as the United States says it has done with Chinese solar panels.

The selective hydrogenation experiments of C3 distillates show that for the pattern of dumped packing, the performance of removing MAPD to less than 15 μ g.

碳三馏分的催化蒸馏选择性加氢研究表明，为使MAPD脱除至15μg。

In this abstract, the considerable influence of absorbing properties of iron-nickel superalloy on the quality of dumet wire will be particularly investigated.

本文着重研究了铁镍合金的吸气性能对杜美丝产品质量的重要影响。

Dumet Wire for Application of Glass-to-Metal Seal

玻璃与金属封接用杜美丝

This paper introduced the research about the micro structure and the properties of the surface layer and the ferronickel core-copper clad boundary layer of dumet wire by means of AES 、 WDS and x-ray diffraction.

利用AES、WDS和x－射线衍射等方法，研究了杜美丝表面层、铁镍芯与覆铜层界面的微观结构与特性。

The wettability between the glass and dumet wire depends on both the cleanliness and constitution of surface layer and the heating conditions.

玻璃与杜美丝的润湿性决定于表面层的净化程度和构成及加热条件。

When you drink the water, think of those who dug the well.
