在网络城市公共空间持续阈限和公共生活缺失的现实下,本文以阈限理论为框架,梳理了艺术博物馆从“时间阈限”到“空间阈限”的历史演化过程,及其分别在精神和身体层面的社交潜能。并以三个具有空间阈限性的当代艺术博物馆为例,分析了介于“结构/反结构”“公共/私密”之间的空间布局和形态特征,指出其设计核心是为了弱化物质空间的存在,从而释放新的社交可能性。

在众多类型的喷头中,液力式雾化喷头因其雾化量大、能耗低、设备简单、经济性好而得到更广泛应用。研究液力式喷头的雾化与沉积特性对改善农药喷施效果具有重要的指导意义。为明确液力式喷头的类型和喷雾参数对其雾化和沉积特性的影响,本文对6种类型的液力式喷头(标准扇形雾XR 110-015、防飘扇形雾DG 110-015、射流扇形雾AIXR 110-015、射流扇形雾AI 110-015、空心圆锥雾t.A 80-015和射流空心圆锥雾AIt.A 80-015)的雾滴粒径、雾滴沉降速度以及沉积分布进行了测试。结果表明:6种供试喷头的雾滴粒径均随喷雾压力的增大而减小,不同喷雾压力下细雾滴(XR 110-015)和中等雾滴喷头(DG 110-015)的体积中值直径(D_(v0.5))差异较小,而粗雾滴(AIXR 110-015)和超粗雾滴喷头(AI 110-015和AIt.A 80-015)对喷雾压力的敏感性更强,其雾滴的D_(v0.5)值随着喷雾压力的增加而急剧下降。雾滴沉降速度与分布特征主要由喷头类型决定,喷雾压力对雾滴沉降速度的影响较小,同一喷头在不同喷雾压力下的雾滴沉降速度分布趋势相似。相同喷雾压力下,细雾滴喷头的平均沉降速度(Vavg)高于其体积中值沉降速度(V_(v0.5)),但随着喷头雾滴的增大,中雾滴喷头和粗雾滴喷头的V_(v0.5)超过其Vavg,且雾滴的粒径越大两者差值越明显。雾滴的沉积结果显示,不同喷雾压力下各喷头的喷雾液流失率均在7.82%~9.75%范围内,各喷头在不同喷雾压力下的流量相似,且略低于其名义流量。喷雾压力对DG 110-015、XR 110-015和AIXR 110-015喷头的雾滴沉积分布均匀性无显著影响,但较高的喷雾压力可提高AIt.A 80-015和t.A 80-015喷头的雾滴沉积分布均匀性。本研究可为田间施药时液力式喷头的选择和作业参数的优化提供理论指导和技术参考。

深入探讨不同攻击角下镐型截齿线性切削破岩特性，以期优化截齿参数设计，提升破岩效率，降低能耗。构建镐型截齿破岩Mat.EM数值模型，开展不同攻击角下线性切削破岩数值模拟，获得截齿力、裂纹扩展模式以及破岩效率等关键参数。结果显示，截齿平均切削力、法向力均表现出随着截齿攻击角度增加而增大；岩石破坏模式随着截齿攻击角的增加由张拉破坏为主转变为压剪破坏为主；在切削深度为12 mm时，岩石破碎效率的最优攻角为40°,在切削深度为15 mm时，岩石破碎效率的最优攻角在55°～60°。不同的攻击角会导致截齿与岩石之间产生不同的破坏模式，进而影响破岩过程中的能量转换与效率。本文研究结论可为镐型截齿的结构参数优化设计提供参考依据，提高悬臂式掘进机的采掘效率。
