粗大地 meaning in English

stoutly

Beryllium powders with the same particle size and various contents of beo were prepared by pre - sintering - acid washing processes initiatively and the influence of beo alone on o mys of beryllium was observed and some new results have been obtained - compared with the content of beo , the distribution of beo in beryllium has more critical influence on mys ; finely dispersed beo along the grain boundaries and in the matrix results in the dispersion strengthening of beryllium matrix and thereby the higher mys value ; on the contrary , the coarser beo particles clustering on the grain boundaries results in negative influence on o mys
开创性地用预烧结? ?酸洗工艺制备了相同粒度、不同beo含量的铍粉，从而开展了beo含量单独对铍材_ ( mys )影响的研究，得出一些新的结果：与beo含量相比， beo在铍中的分布状态对_ ( mys )的影响更大。沿晶界、晶内弥散分布的较细小beo对基体铍有弥散强化作用，使_ ( mys )即较高；如果beo较粗大地成簇状聚集在晶界，反而对_ ( mys )有不良的影响。
