However, up to now, main research works are only limited to piecewise linear affine systems.
然而，迄今为止，主要的研究工作仅局限于分段线性仿射系统。

The temperature of fuel pellets can be limited by linear power density restriction.
通过限制线功率密度，可以限制燃料芯块的温度。

A method of enhancing the precision of linear borderline measurement is proposed, and the highest precision that the limited density data sampling can reach is discussed.
