The change of physical and mechanical properties slope rock mass in open-pit mines seasonally frozen area under the action freeze–thaw cycles is one main reasons for instability. In this paper, taking parameters coal seam sandstone layer Beitashan Pasture Open-Pit Mine Xinjiang as research object, considering combined effect frost-heave tensile stress crack perpendicular to surface three-dimensional confining pressure crack, criterion cracking fractured freeze-thaw condition determined by...
In this study, the strength, elongation, and fatigue properties of 7005 aluminum alloy plates with different configurations precipitates were investigated by means tensile tests, microstructural observation. We found that number size GP zones in an plate matrix increased distribution was more uniform after aging time extended from 1 h to 4 at 120 °C, which led a rise both strength elongation extending time. The life shortened slightly first, then significantly prolonged, again 192 stress...
以3.5 mm厚的Al-5.41Zn-1.79Mg-0.45Mn合金板为例,观察基体析出物(MPts)与晶界析出物(GBPs)的尺寸关系,系统研究了沉淀物构型对合金板拉伸和疲劳性能的影响,该材料经过固溶处理后,在120 °C和200 °C下进行不同时间的时效。结果表明:当基体中完全存在6.5 ± 0.5 nm半相干η'相时,GBPs为η相,尺寸为27 1 nm,沉淀自由区(PFZ)宽度为30 nm,合金板具有最佳的合成性能,屈服强度、抗拉强度分别为461±6 MPa, 107个循环±应力比为20.5 MPa/205 MPa时,疲劳寿命分别为495 6 MPa,×为(9.7 5.1)。在200 °C时效的合金板中观察到MPts与GBPs之间的尺寸关系异常,MPts的尺寸比GBPs粗1.4倍。合金板在120 °C时效1 h的疲劳寿命比在200 h的合金板长35倍以上,但强度和伸长率大致相同。
To retrospectively investigate the effect of a mobile app-based self-care diary, nursing management method, on post-heart transplantation diabetes. A retrospective analysis was conducted general data 87 patients who underwent heart in Cardiac and Thoracic Vascular Surgery Department Nanjing First Hospital between January 2018 December 2023. Based were divided into control group that received routine measures (n=47 cases) an observation implemented APP-based diary combined with (n=40 cases)....
