Dizhen xuebao, 2022 利用传统三极接地电阻率测量方法对井下电极接地电阻进行测量会存在较大的测量误差，表明该方法已不适用于井下电极接地电阻测量。针对此问题，提出了利用台站现有地电阻率仪器进行电极接地电阻测量的新方法—直接测量法，并使用传统三极法和直接测量法对北京平谷地震台井下观测供电电极接地电阻进行了测量。测量结果表明：与传统三极法对比，直接测量法的测量结果更为准确、可靠，而且节省人力、物力和时间。

Research on Calibration Methods of Volumetric Motion Errors for Large Scale Coordinate Measuring Machine [PDF]
, 2016 三坐标测量机作为工业零部件的主要检测设备，具有通用性强、自动化程度 高、测量精度高等特点，被广泛应用于工业制造及科研技术开发领域。随着制造 技术的发展，零部件朝着大尺寸，复杂面形，高精度等方向发展，这使得大行程 三坐标测量机不可或缺，同时也对大行程三坐标测量机的检测精度提出了更高的 参数要求。然而，目前大行程三坐标测量机的误差标定仪器主要是激光干涉仪和 激光跟踪仪，它们在标定过程中存在使用成本高、测量周期长、需配专用调试人 员等不足，无法得到广泛应用。鉴于此，本文创新性地提出了一种基于球杆仪循 ...

Wildlife Letters, EarlyView.Climate change drives shifts in suitable habitats for Eurasian lynx and its prey (hare, roe deer) in Mohe, Daxing'anling Mountains. Under RCP scenarios, moderate warming (RCP4.5) promotes substantial habitat expansion, while high‐emission conditions (RCP8.5) lead to strong expansion in the 2050s but slower gains and partial contraction by the 2070s ...

Wildlife Letters, EarlyView.Using a 3‐year, broad‐scale camera‐trap network in western Kansas, we tested whether coyotes and American badgers exhibit spatiotemporal patterns consistent with coordinated hunting. Despite high diel activity overlap, detection‐conditioned co‐detections occurred far less frequently than expected under independence, and short‐term temporal sequencing ...

Evaluation of the Up-to-date Approach SBA for Measurement of Water Leaving Radiance [PDF]
, 2015 SBA(Skylight-blockedapproach)是新近提出的直接测量离水辐亮度Lw的方法(Leeetal.,2013)。该测量方法是由表面之上法改进而来。辐亮度光谱仪镜头处安装上一个蔽光元件——遮光锥，测量时遮光锥的末端稍稍插入水中但光谱仪镜头保持在水面之上。如此一来，遮光锥将水面反射的光完全阻挡，来自水中的辐亮度穿过水面后自然转变为Lw并被光谱仪所接收，从而实现了由光学传感器直接获得Lw的突破。传统的测量方法，包括剖面法和表面之上法，只能测量相关参数，然后通过物理模型计算得到Lw。然而 ...
