Their tensile strength and elongation at break were obviously dependent on irradiation dose and blending ratio of the polymers.
该膜的抗张强度和断裂伸长率则明显地依赖于辐射剂量和聚合物的混合比例。

Cyclic steam stimulation is a major way of recovering heavy oil at present. Efficient development is highly dependent on rational using of steam energy and improving oil-steam ratio.
