  1. 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

    開創性地用預燒結? ?酸洗工藝制備了相同粒度、不同beo含量的鈹粉,從而開展了beo含量單獨對鈹材_ ( mys )影響的研究,得出一些新的結果:與beo含量相比, beo在鈹中的分佈狀態對_ ( mys )的影響更大。沿晶界、晶內彌散分佈的較細小beo對基體鈹有彌散強化作用,使_ ( mys )即較高;如果beo較粗大地成簇狀聚集在晶界,反而對_ ( mys )有不良的影響。
  2. Results show that : ( 1 ) for each particle size of andalusite, variation tendency of the properties of the material is generally the same : the maximum of bulk density, compressive strength and rupture strength appears in the range of 5 % - 10 % content of fiber, these properties of the material remarkably decrease as the fiber content exceed 10 % ; while at the same fiber content, the properties of the material increase with the increase of firing temperature

    結果表明: ( 1 )對于不同粒度的原料,性能變化規律大致相同:在同一燒成溫度下,體積密度、常溫耐壓強度、常溫抗折強度在5 10之間出現峰值,加入量超過10之後材料的性能明顯下降;在相同的纖維含量下,隨著燒成溫度的提高,試樣的各項性能均有所上升。
  3. Fractal characteristics of particle size distribution of coal series kaolinite during calcination

    煅燒煤系高嶺土粒度分佈的分形特徵
  4. The nature of sand movement depends on the particle size, shape, and specific gravity in respect to the associated velocity and turbulence.

    泥沙運動的性質取決于顆粒的大小、形狀和比重並與流速和紊動有關。
