查询词典 hardness

The experimental results show that the size of large particles on coatings surface was decreased obviously by N ion beam assisting bombardment, and surface morphology was optimized. Unitary TiN phase was obtained and softer Ti2N phases were eliminated by N ion beam assisted bombard. As the energy of bombard increased, TiN (111) crystal orientation gradually reduced and (200) gradually enhanced. The micro hardness of coatings reinforced too.

结果表明：N离子束辅助轰击，能够有效地减少和降低膜层表面&大颗粒&的数量和尺寸，消除了膜层中较软Ti2N相，得到了单一的TiN相，随着轰击能量的增加，TiN相结构不发生变化，TiN（111）取向逐渐减弱，而（200）取向逐渐增强。N离子束辅助轰击能量的增加，提高了膜层的显微硬度。

Results show that when the thickness is less than 0.7 nm, Si3N4, normally amorphous in deposition state, could form a NaCl-type pseduocrystal structure due to the template effect of TiN crystal layer. Crystallized Si3N4 layers and TiN template layers grow coherently into columnar crystals with (111) preferred orientation. Correspondingly, the hardness of the films was enhanced to a maxim value of 38.5 GPa, showing a superhardness effect.

结果表明，在TiN调制层晶体结构的模板作用下，溅射态以非晶存在的Si3N4层在其厚度小于0.7 nm时被强制晶化为NaCl结构的赝晶体，多层膜形成共格外延生长的（111）择优取向超晶格柱状晶，并相应产生硬度显著升高的超硬效应，最高硬度达到38.5 GPa。

The results indicated that visitors' activities caused a serious influence on the soil in the park, especially in the two most used scenic spots-Yellowstone Village and Gold Whip Stream. The impact of tourism on soil mainly occurred within 3 m along the trails. The impact shapes are classified into six type as single-sided node type, double-sided node type, cross node type, single-sided linkage type, double-sided linkage type and short-cut linkage type. Of six types of impact shapes, the single-sided node type and double-sided type were dominant. The average water contents of soil for six scenic spots at sample areas of 1 m, 2 m and 3 m from trial is 36.6%, 24.5% and 2.2% lower than that of the control area, respectively. The average soil hardness for six scenic spots at 1m, 2 m, and 3m from the trails tramped increased 167.9%, and 122.2%, and 15.8%, respectively, compared with the control area. Soil bulk density increased 26.5% at 1 m and 20.9% at 2 m from the trails.

结果表明：游客活动对张家界世界地质公园土壤产生了较大的影响，特别是在游客相对集中的黄石寨景区和金鞭溪景区，影响十分明显；游客对土壤影响的范围主要发生在距游道两侧3米以内的范围；公园内土壤影响形态可分为单侧节型、双侧节型、单侧链型、双侧链型、十字节型和捷径链型6种类型，其中又以单侧节型和双侧节型为主；在六个景区中，距游道边缘1米、2米及3米范围内土壤的平均含水率较对照区分别低了36.6%、24.5%和2.2%；与对照区相比，距游道边缘1米、2米及3米的土壤硬度分别增加了167.9%、122.2%和15.8%，而距游道边缘1米和2米范围内的土壤容重则分别比对照区增加了26.5%和20.9%。
