摘要翻译：
本文研究了Murre关于有理Chow群结构的猜想，并给出了具体的Chow-Kuenneth投影。更确切地说，我们研究的例子是具有nef切丛的变种。对于具有nef切丛的曲面和三重曲面，得到了满足Murre猜想的显式Chow-Kuenneth投影，并验证了motivic Hard Lefschetz定理。

英文摘要：
In this paper, we investigate Murre's conjectures on the structure of rational Chow groups and exhibit explicit Chow--Kuenneth projectors for some examples. More precisely, the examples we study are the varieties which have a nef tangent bundle. For surfaces and threefolds which have a nef tangent bundle explicit Chow--Kuenneth projectors are obtained which satisfy Murre's conjectures and the motivic Hard Lefschetz theorem is verified.
