Sample ' s analyses and tests in laboratory, this thesis makes a detailed research on holocene deposits characteristics of mu us desert, especially on characteristics of grain size composition, which break through previous description of determining the nature and gain a series of number indexes. at the same time, this thesis has also researched arenaceous source on every part of mu us. firstly mu us desert ' s forming process is deeply influenced by the east asian monsoon, the grain size gradually becomes smaller, while the magnetic susceptibility becomes larger from northwest to southeast this phenomenon not only appears on the surface of mu us, but also obviously reflects on the same layer of different places
根據大量野外詳細考察和室內樣品分析與測試，本文對毛烏素沙地全新世地層沉積特徵做了細致的探討，尤其對區域地層的粒度組成特徵做了進一步的研究，突破了以往的定性描述，得出了一系列量化指標；結合野外的考察工作，對其不同地區的沙質來源做了詳細分析，主要得出以下結論： 1 、毛烏素沙地形成過程深受東亞季風影響，粒度自西北向東南逐漸變細、磁化率值逐漸變大。 -
This work carries out a temporal - spatial analysis and comparison in facial pattern, grain - size, and susceptibility of the sediments of the hunshandake sandy land ( hsl ) on the basis of studies of more than fifty geological sections, a number of samples collected from surface sands as well as results derived from previous studies. the preliminary results of this work provide new environmental information of the working area, which makes it possible to have a brief discussion about the evolution of the hsl since the late glacial epoch. this work can be summarized as the followings
晚冰期，渾善達克沙地全面擴張，達到了沙漠化最大規模，剖面中的古風成砂是最直接的證據，此時氣候乾冷；全新世早中期，渾善達克沙地成壤比較好，是一個大面積成壤期，相當于全新世適宜期，此時氣候暖濕；全新世晚期，渾善達克沙地沙漠化正過程加強，在沙地各剖面上普遍發育風沙沉積，氣溫較乾冷；目前：渾善達克沙地為另一成壤期，成壤作用相對于適宜期較差，氣候乾暖。 -
The results of pure cu show ecap can produce bulk material of submicrometer level indeed. as the number of passes increases, the initial structure of pure cu has been refined largely. after six passes, i. e. the equivalent true strain of 4 ~ 5, the grain size gradually becomes stable and uniform
對純銅室溫ecap晶粒超細化行為及組織穩定性的研究表明： ecap技術的確能制備出亞微米級的塊體材料，隨著ecap道次的增加，純銅的組織被大大細化， ecap六道次（即等效真應變4 5 ）后，晶粒尺寸趨于穩定，硬度基本飽和。 -
When a larger number of grains relative to the size of vegetative parts is produced, more nitrogen will be needed to support grain growth, and there will be a sharper drain in leaf nitrogen content
當相對于營養部分來說生成較大數量的籽粒時，更多的氮要用來支持這些籽粒生長，葉片含氮量會急劇下降。 -
The test results show that : 1. under giving conditions, two explosives with the same atomic number ratio have similar combustion performances, 2. the pressed charge and the powder charge shows observably different combustion characteristics, 3. within 211. 7 m - 635. 0 m, decreasing the grain size may enhance combustion velocity
通過對測試結果的分析表明，在特定條件下具有相同原子組成比例的炸藥，其燃燒性能相近；同種炸藥的藥柱和藥粉燃燒性能差異較大；在211 . 7 635 . 0 m范圍內， hmx 、 rdx顆粒越細，燃燒越快。
