    The present application provides a method and a device for preventing apparent death of a window, and relates to the field of computer technology. The method comprises: when a child window is created by a thread, a middle window is firstly created in a thread different from the thread on which each child window of a window system is positioned, wherein the middle window is the parent window of the current created child window, and the parent window of the middle window is the frame parent window; the thread on which the current created child window is positioned differs from the thread on which the frame parent window is positioned; if a child window has the apparent death phenomenon, the apparent death message of the apparent death child window is sent to the thread on which the corresponding middle window is positioned; and the middle window and the apparent child window are separated from a window frame by the thread on which the middle window is positioned. By the present application, the middle window corresponding to the apparent death child window can be separated from the window system; the apparent death state of the integral window system caused by the apparent death of the child window is avoided; and the apparent death problem of the integral window system caused by the apparent death of the child window in the windows system of the Windows is solved.

  • 利用电解锰渣制备As(Ⅲ)吸附材料及其性能研究

    通过对工业废弃物电解锰渣(electrolytic manganese residues, EMRs)进行改性制备As (Ⅲ)吸附材料(改性EMRs),探究了NaOH用量、超声及微波对其表面结构及吸附性能的影响.结果表明:该工业废渣在固液比M(EMRs)∶V(NaOH, aq)=1∶10(CNaOH,aq=2.0 mol·L-1)条件下,经超声反应(200 W) 2 h脱除大部分Si、S、Ca后,再微波(700 W)反应5 min以使Fe、Mn等活性吸附基团在其表面沉积,最后经105℃烘干制得改性EMRs.SEM结果表明,EMRs改性后表面形成片层纳米结构,对砷具有良好的吸附性能,可将初始As (Ⅲ)浓度为50 mg·L-1废水出水中砷降至0.042 mg·L-1,符合国家地表水环境质量标准Ⅰ类水质量要求(GB 3838—2002);同时,经3% NaOH溶液再生处理后可继续使用.XPS结果表明,改性EMRs吸附砷性能与其表面Fe3O4、FeOOH、MnO2等对As (Ⅲ)具有吸附作用或氧化作用的活性物种的增多密切相关.

  • Heterodyne multi-frequency method for 3D profile measurement

    Lou Xiaoping   Lv Naiguang   Sun Peng   Duan Fengxia   Lin Yimin  

    A binocular structured light measurement system using heterodyne multi-frequency method is researched in this paper. Three steps must be done to recover 3D profile information: cameras calibration; points matching; 3D information reconstruction. The intrinsic and extrinsic parameters of cameras are calibrated by Zhengyou Zhan's method([1]). Stereo vision model is the basic rule of 3D recovering. Techniques of phase shift and heterodyne multi-frequency are used to aid points matching. Some coded digital fringes are projected to the free-form surfaces and corresponding images are captured by two cameras simultaneously. The wrapped phase map is obtained through four-step phase shift. In a single cycle, phase value is calculated using arctangent function and it is between -pi and pi. The heterodyne multi-frequency method is applied to get the absolute phase map. When the number of frequencies is changed from 2 to 3, or 4, the unwrapping accuracy and matching results are improved. The processing theory and experimental results are illustrated and analyzed. The experimental results show that accurate and reliable phase result can be obtained on phase map boundaries and break points, which proves its feasibility in industrial situations.
