Please polish the following paragraphs into academic language:Improving the high-temperature mechanical properties of low-activation steels is a frontier topic in nuclear fusion reactor cladding materials. The preparation of ODS low-activation steel by powder metallurgy method is not only complicated, but also has poor processing performance, which makes it difficult to be used in large scale. The high-temperature creep properties and irradiation resistance of CNAs low-activation steels reinforced with nano-MX phase do not reach the level of ODS low-activation steels. It is difficult to effectively control the thermodynamics and kinetics of oxide formation in ODS low-activation steels prepared by melt-casting process, and their tissue uniformity and mechanical properties need to be improved. We propose a new idea of additive manufacturing ODS low-activation steel, using the oxygen atmosphere in the printing process to control the thermodynamic and kinetic processes of oxide formation, so that the active element Ti is oxidized in situ in the matrix to form diffuse titanium oxide with a size of about 10-30 nm, which greatly improves the high-temperature mechanical properties of additive manufacturing low-activation steel, and the 600°C tensile strength is increased from 470 MPa to 660 MPa, which provides a new idea for the integrated preparation of complex components of ODS low-activation steel.

提高低活化钢的高温力学性能是核聚变反应堆包壳材料的前沿课题。通过粉末冶金法制备ODS低活化钢不仅复杂，加工性能也较差，难以大规模应用。加强了nano-MX相的CNAs低活化钢的高温蠕变性能和放射线抗性尚未达到ODS低活化钢的水平。在熔炼铸造工艺中，难以有效控制ODS低活化钢氧化物形成的热力学和动力学过程，其组织均匀性和力学性能需要改善。本文提出了一种新的ODS低活化钢增材制造的思路，利用印刷过程中的氧气环境控制氧化物形成的热力学和动力学过程，使活性元素Ti在基体内原位氧化，形成约10-30nm大小的扩散性钛氧化物，大大提高了增材制造低活化钢的高温力学性能，使600°C的拉伸强度从470 MPa增加到660 MPa，为ODS低活化钢复杂部件的集成制备提供了新思路。

polish the below content in an academic way: However, prior work has not yet considered them jointly. \cite{add17} and \cite{14} use convergence rate to measure the performance of FL, without considering energy consumption. Similarly, \cite{add31} and \cite{add32} consider only the learning latency in the formulations in the optimization problem and simulations.

然而，以往的研究尚未将它们结合在一起进行考虑。文献\cite{add17}和\cite{14}使用收敛速率来衡量分布式学习的性能，但没有考虑能量消耗。同样，文献\cite{add31}和\cite{add32}在优化问题和模拟中仅考虑了学习延迟。
