friability n.脆性,易碎性。

friable

After pretorsion the successor tensile yield limit and strength limit both improved very highly , but the trend of the increase of the strength limit was suspended till the pretorsional capacity reached 17 , when the pretorsional capacity was greater than17 ( prestrain value was 81 . 19 % of total strain ) , the successor strength limit rapid failed and approached the yield limit . this illustrate the a3 steel specimen translate from plasticity into friability after pretorsion strengthen . when the specimen was operated by tension - torsion action , the yield limit had very large improved , but the strength limit changed very little . furthermore , the trend of the increase of the strength limit was suspended till the pretension capacity reached 0 . 25 ( prestrain value was 66 . 93 % of total strain ) A3鋼試件在預扭轉后,后繼拉伸屈服極限和強度極限均有很大提高,但強度極限的增大趨勢到預扭轉量為17為止,預扭轉量大于17 (預應變值為總應變的81 . 19 )后強度極限迅速下降,與其屈服極限接近,這說明a3鋼試件經預扭轉強化后逐漸由塑性轉化為脆性。該預應變值為a3鋼試件的韌脆轉變點。 a3鋼試件在拉伸-扭轉作用下,屈服極限有很大提高,但強度極限沒有多大改變,而且,屈服極限的增大趨勢到預拉伸量為0 . 25應變(預應變量為總應變量的66 . 93 )后就不再增加。

The chief reason of the development of the case - based reasoning is that there are lots of difficulties to obtain knowledge in the traditional rule - based reasoning and that cbr systems don “ t remember the solved problems , which result in low efficiency of reasoning , disability to deal with abnormal things and the rather friability of the system ability Cbr興起的主要原因是傳統的基于規則的系統在知識獲取問題上存在困難,對于處理過的問題沒有記憶,導致推理效率低下、不能處理事例的例外情況,整體性能較為脆弱,而cbr恰好能夠解決以上問題。
