Based on the theory of unsaturated soil mechanics and the properties of compacted expansive soil, this paper takes the northern part k12 + 840 - k12 + 920 of nanning urban highway as an example to studies some aspects of lime improvement of expansive soil and the technology of construction. the chief content of this paper is : the lime improvement mechanism of expansive soil ; confirm the technical parameters of lime mixed from the results of test in laboratory ; the scale - down test to define the maximum effective grain size of expansive soil when it is improved by lime ; by building bank slope model and making use of finite element seepage flow program of saturated - unsaturated to calculate the examples, this paper simulates the humidity site in order to checkout the effect of lime improvement ; studies and proves that it is feasible to mix blocky expansive soil and pulverous lime, and to fill roadbed by common construction machines etc.
本文研究的工作就下述幾個方面展開：用石灰改良膨脹土的機理；通過室內試驗確定摻灰的技術指標；在室內進行膨脹土摻灰的最大有效粒徑的模擬試驗，即鈣離子水試驗，由此總結出「粉?塊」灰?土攪拌工藝的有效性、合理性和可行性；用數值方法對路堤使用期的濕度場進行模擬，並與路堤的強度?變形的計算域耦合，以檢驗土性改良的效果，從而探索一種描述改良膨脹土路堤運行工況的數值方法；用現有最常用的且費用最低的施工機具，對灰?土進行「粉?塊」攪拌摻和及路基的填築施工等。 -
This paper conbined with the indoor test and the scene test road, through the synthetical analysis of the factors of influencing densification effect for the densification thickness of filling stone roadbed. the maximum grain size of fill material, densification machinery and densification frequency et al. advanced a control norm of the maximum grain size and piy of compression, established ration evaluating the control standard of densification quality of filling stone roadbed under overload. comparing with result of indoor test and the scene test road, studied on theory of densification in different kinds of stone material and perfected the control system of the densification of filling stone roadbed under overload
結合室內試驗和現場試驗路的實測數據，通過對填石路基的壓實厚度，填料最大粒徑，壓實機械及壓實遍數等影響壓實效果的因素的綜合分析，提出填石路基的最大粒徑和攤鋪厚度的控制指標，建立定量評定超重載交通下填石路基壓實質量的控制標準，並對照室內試驗和現場試驗結果，研究不同石料條件下的壓實理論，補充完善了填石路基壓實控制指標體系。 -
A modified definition of polarization resistance calculated from the equivalent circuit of eis make its value dependent on the grain size. in anodic polarization test ( sweeing and stair - steps ), the maximum ( critical ) current density increases while the passivation potential and breakdown potential lowers with the reduction of the grain size. fegsem images showed the grain growth and pitting corrosion of the nc copper surface, uniform corrosion in the mc copper surface and the broken passivation layer in both surfaces
在陽極極化實驗（包括掃描法和臺階法）中，致鈍電流雖晶粒尺寸減小而增大，而致鈍電位和擊穿電位都隨著晶粒細化而降低。 fegsem照片發現了納米晶銅的晶粒長大和孔蝕，微米晶銅表面的均勻腐蝕，和兩種銅表面破碎的鈍化膜。 -
The results show that the ma can accelerate the diffusion in solids. during the ma process, the size of grain in the sample sharply decreases to 65. 27nm after 30 minute milling and to 4. 14nm after 20 hour milling, while the microstrain of the grain increases firstly, reaching the maximum 0. 422 after 10 hour milling and then decreases
通過試驗發現，機械合金化可以加速固態擴散，隨著球磨的進行，粉末晶粒尺寸急劇下降， 30分鐘后達到65 . 27納米， 20小時后達到4 . 14納米；微觀應變先增大， 10小時達到最大值0 . 422 ，隨后減小。 -
By the control of deposition process, it is succeeded in preparing ( 100 ) high - orientation diamond films with maximum single grain ' s size about 100 100um and 4. 693 ? fwhm ( full width of half maximum ) in xrd shocking scan curve, and also preparing 75mm large area transparent diamond films with 68. 3 % average transparence
通過對沉積過程的控制，制備了（ 100 ）高取向金剛石膜，搖擺曲線半峰寬（ fwhm ）為4 . 693 ，最大單個晶粒的尺寸為100 100 m ，同時還制備了75mm的大面積透明金剛石膜，平均透光率達68 . 3 。
