This paper discusses land-use changes in the interlock area of farming and pasturing (IAFP) in northern China. It presents detailed analyses of land-use features in the IAFP, which are controlled by the macro geomorphic units and geophysical conditions-constraints or advantages. Additionally, it selects some indicators, according to the availability in acquiring and processing their quantitative data, to analyze the canonical correlations between the typical conversion of grassland and geophysical conditions. The preliminary study indicates that the physical conditions are of great advantages to the development of grassland. There exists significant correlation between land use change and some geophysical conditions.

采用化学相分析、X射线桁射、SEM等方法研究了微量Mg、Zr在GH698合金析出相间分配规律,及其对γ′的相组成、热稳定性和晶格常数的影响。还研究了Mg在铸态合金经1170℃加热时的扩散现象。结果表明,当合金中Mg含量≤0.012％时,Mg主要进入γ-固溶体,γ′中Ti(Nb)/Al(原子％)比值随Mg含量增加稍有提高;当Mg含量>0.012％时,Mg进入γ′和碳化物中,γ′的Ti(Nb)/Al比值则下降。可以认为,合金强度性能与此比值有关。加入到合金中的Zr主要进入γ′,增大γ′的晶格常数,提高γ′的溶解温度,细化γ′的粒度。

本工作用金相、电镜、相分析和X光结构分析等方法研究了MO、Nb对一种镍基变形涡轮盘合金组织结构和力学性能的影响。结果表明,合金中γ′相量、尺寸和分布以及碳化物的种类和分布与合金Mo,Nb元素含量密切相关,从而影响合金室温和高温下力学性能。 Nb提高γ-γ′相间错配度,表现为提高合金屈服强度。Mo是促进M23C6析出的元素、Nb是抑制M23C6析出的元素。添加Mo、Nb都使γ′相数量增加并在给定的热处理条件下使大小γ′相均匀分布于基体。为合金Mo、Nb最佳成分控制提供了一个依据。
