本文對非荷載裂縫，特別是溫度?收縮裂縫進行了調查研究，並對兩端或四周約束的梁、板和底部約束的地下連續墻進行了收縮應力分析，發現國內外有關文獻給出的收縮計算公式沒有考慮泵送商品混凝土的水泥用量、外加劑使用、骨料粒徑和砂用量等因素的影響，計算出的混凝土收縮量往往偏小；另外， 《規范》中針對溫度?收縮裂縫的構造措施不足。Abstract : the reasonable distribution of mix bulk density and partical size on the transverse and lenghwise direction of sintering pallet, the relationship between segregation index and mix bulk density were discussed. the ways for improving mix bulk density, enhancing mix partical segregation, decreasing side wall effect and increasing bed surface flatness were proposed
文摘:論述了臺車上橫向、縱向混合料容積密度及粒度的合理分佈，偏析指數和混合料容積密度的關系，提出了改善臺車上混合料容積密度，加大混合料粒度偏析，降低邊緣效應及提高料面平整度的布料途徑。Results indicate that with the approximation of _ ( 0 ) _ ( 0 ) - grtlneisen equation of state is usable to describe the release isentrope of ofhc copper in the present pressure range. in addition, the difference ( w - 2u ) becomes greater with the increase of shock pressure, where w is the measured particle velocity at the final release state ( 1 atm ) and 2u is computed from the mirror line of hugoniot
卸載路徑的計算和分析表明：在所研究的壓力范圍，無氧銅的等熵卸載過程用gr neisen狀態方程在_ 0 _ 0 =近似下的描述是適用的；卸載到一個大氣壓的終態粒子速度w與鏡像反演的粒子速度2u的偏差，隨沖擊波壓力的增加而增大。With the widespread and profound impacts of global change on the natural elements and progress, the society and economy, and even the human activities, the study of global change has become one of the most active frontiers in the current earth science research field. especially, climatic and environmental changes of holocene and human history is a very important time scale of the study of global change. however, the geographic surroundings and the natural environment of the southern margin of tarim basin, which lies in the hinterland of eurasia continent, are so special that it is difficult to obtain the proxies indicating its environmental evolution
