求翻译：但是通过总结国内外的研究发现通常的单一处理方法由于优缺点共存，常常是在提高某方面性能的同时，牺牲材料另一方面性能，对复合材料的综合力学性能改善并不理想。是什么意思？

However, by summing up the research at home and abroad is usually a single approach as the advantages and disadvantages of co-existence, often at the same time improve the performance of certain aspects of sacrificial material on the other hand performance, improve the mechanical properties of compo

However, through the lessons at home and abroad and are typically found on a single approach for advantages and disadvantages, and it is often co-exist in some of the performance, at the expense of another performance of composites, composite mechanics performance improvement is not the ideal.

But through summarizes the domestic and foreign research discovery usual sole processing method as a result of the good and bad points coexistence, on the other hand is frequently while enhances some aspect performance, the sacrifice material the performance, is not ideal to the compound materials c

But by summarizing research at home and abroad are usually single treatment method due to the advantages and disadvantages of coexistence, often while improving performance, sacrificing material on the other hand, on comprehensive improvement of mechanical properties of composite materials is not id
