  1. The character of tube roll mill is that it combines the advantages of ball mill and roller, then great improves the grinding efficiency through the study of the grinding theory of tube roll mill, pressing stress, grinding effect and the comparation between roller and vertical mill, this text combined the national important technology equipment crert item - - tube roll milling developing item, gets following results : firstly, because of the special structure of tube and roll, powder from single particle grinding in the early peried contincely transit press grinding stage, it better stops the loss of splash energy, secondly, during the grinding progress, powder form loose to dense fully uses the nonsmoth surface of particle and stress focus to make its stress lower than roller " s

    本文結合國家重大技術裝備國產化創新項目-筒式輥碾磨開發項目，通過對筒輥磨的粉磨機理、層壓應力的分析、粉磨效果的研究及與輥壓機、立磨粉磨效果、粉磨機理的比較，可知：首先，由於筒與輥的特殊結構方式，筒輥磨內粉體由初期的單顆粒破碎逐漸過渡到層壓粉碎階段，較好地防止了飛濺能的損失，其次，在粉磨過層中，粉體由疏鬆到密實，充分利用了顆粒的非光滑表面及應力集中效應使其應力低於輥壓機。實驗證實，筒輥磨的粉磨效果大大優于立磨和輥壓機。

    同時針對找形分析中的動力鬆弛格式，本文提出了全新的控制網格變形的動力鬆弛法，此方法能夠有效地解決膜結構找形分析中網格的大變形問題，克服了在曲率較小處網格過于稀疏的缺陷，在曲率較小處保證了單元的密度和初始構形的精度，並且收斂性較好，為準確進行荷載分析和裁剪分析奠定了基礎。
  7. Based on the knowledge of characteristic of unsaturated soils. the law of suction change with moisture content and density is got from suction experiment, which revealed that the matrix suction changes obviously with density especially in low moisture content, and with the same moisture content, if the density is gradually added, the value of matrix suction first is lowed, then added and finally lowed, this phenomenon is probed into in this paper

    基於對非飽和土特性的認識，進行了基質吸力的試驗研究，得到了基質吸力隨含水量和密度的變化規律，試驗揭示出：基質吸力隨密度的變化是明顯的，含水量越低，這一趨勢越明顯，在含水量相同的情況下，當砂土從疏鬆狀態逐級變密時，吸力值經歷變小、變大、又變小的過程，文中對造成這一現象的原因作了初步分析。
