along the grain中文什么意思
例句与用法
- A block of wood on whose surface a design for printing is engraved along the grain
木刻一块表面上有沿木纹雕刻的用以印刷的图案的木头 - Exposed solid wood parts , such as handrails , balls and claws , should be wiped with a clean and damp white cloth , along the grain
外露的实木部件，如扶手、滚珠和脚爪等，应该用一块干净、潮湿的白布擦干净，一定要顺着木纹方向擦。 - Under the tensile stress , the fracture mode of za27 alloyed with si or mn is a mix type fracture - the plastic fracture and the brittle fracture are coexistence . cracks are mainly stemmed from brittle phases of si and mn and develop along the grain boundary
适宜的加锰量为0 . 4 - 0 . 8 ；在拉伸应力作用下加入si或mn后的za27 ，合金的断裂均为混合型断裂，既有塑性断裂，也有脆性断裂。 - 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。
