"基于Carbide.c++的Symbian开发环境搭建,涵盖了SymbianOS的介绍,S60 SDK版本及其对应关系,以及安装和兼容性问题。" SymbianOS是一个专为移动设备设计的操作系统,尤其在智能手机市场中具有广泛的应用,尤其是在Nokia的设备上。SymbianOS提供了强大的功能,使其能够适应各种移动设备的需求。Nokia基于SymbianOS构建了不同的人机界面平台,如Series40、Series60和Series80,其中Series60是针对中端市场的智能平台,逐渐取代Series40,并且发展出了多个版本。 S60 SDK是开发者进行S60应用开发的重要工具,包含了SymbianOS C++ API、S60 UI API、支持库以及相关的文档。这些SDK对应不同的SymbianOS版本,例如S60 1st Edition, FP1对应SymbianOS 6.1,而S60 3rd Edition, FP2则对应SymbianOS 9.3。选择SDK时,开发者需要根据目标设备或应用需求来决定,因为不同版本之间可能存在兼容性问题。 安装S60 SDK时,需要注意的是,从S60 3rd Edition开始,由于引入了新的特性和限制,导致与之前的S60 2nd Edition不兼容。这意味着在S60 2nd Edition上开发的应用需要进行移植才能在S60 3rd Edition上运行,而S60 3rd Edition的程序通常可以向下兼容。因此,开发者可能需要安装多个SDK版本以支持不同平台的应用开发。 Carbide.c++是用于Symbian开发的主要IDE,它提供了一个集成的开发环境,包括代码编辑器、编译器、调试器等功能,使得Symbian应用的编写和调试更为便捷。在搭建Carbide.c++的开发环境时,首先需要下载并安装合适的S60 SDK,然后配置Carbide.c++,设置好SDK路径和编译器选项。 整个环境搭建过程可能涉及以下步骤: 1. 下载并安装S60 SDK:选择适合目标设备或开发需求的SDK版本。 2. 安装Carbide.c++ IDE:获取最新版本的Carbide.c++,确保它支持所选的S60 SDK。 3. 配置IDE:在Carbide.c++中设置SDK路径,通常在"Tools > Options > Build > Platform"中进行。 4. 创建项目:根据应用需求,创建一个新的Symbian项目,并选择对应的设备和SDK。 5. 编写代码:利用Carbide.c++的编辑器编写C++代码,实现应用功能。 6. 编译和调试:通过IDE进行编译和链接,如果一切顺利,可以在模拟器或实际设备上运行和调试应用。 在Symbian开发中,了解不同版本之间的兼容性,掌握正确的SDK选择和IDE配置,是成功搭建开发环境的关键。此外,开发者还需要熟悉SymbianOS的内存管理、线程模型、UI框架以及文件系统等核心概念,以便更好地开发高效且稳定的Symbian应用程序。

WIDE bandgap devices, such as silicon carbide (SiC) metal–oxide–semiconductor field-effect transis- tors (MOSFETs) present superior performance compared to their silicon counterparts [1]. Their lower ON-state resistance and faster switching capability attract lots of interest in high-power- density applications [2]. Faster switching speed enables lower switching loss and higher switching frequency, which is benefi- cial to high-efficiency and high power density. However, severe electromagnetic interference (EMI) and transient overvoltage issues caused by fast switching speed jeopardize the power quality and reliability of converters [3], [4]. Therefore, there is a tradeoff between efficiency and reliability in the choice of switching speed. An optimized design should ensure theoperation within both safe-operation-area and EMI limits, and switching loss should be as small as possible. A prediction method of switching performance is important and helpful for designer to evaluate and optimize converter design. The most concerned switching characteristics are switching loss, dv/dt, di/dt, and turn-ON/OFF overvoltage generally. These characteristics are crucial for the design of heatsink, filter, and gate driver.

n the present research, a hybrid laser polishing technology combining pulsed laser and continuous wave laser was applied to polish the surface of laser directed energy deposition (LDED) Inconel 718 superalloy components. The surface morphology, microstructure evolution and microhardness of the as-fabricated, the single pulsed laser polishing (SPLP) and the hybrid laser polishing (HLP) processed samples were investigated. The results revealed that the as-fabricated sample has a rough surface with sintered powders. In the matrix, the NbC carbide and Cr2Nb based Laves phase array parallel to the build direction and the small γʺ-Ni3Nb particles precipitate in matrix uniformly. The surface roughness of the as-fabricated sample is 15.75 μm which is decreased to 6.14 μm and 0.23 μm by SPLP and HLP processing, respectively. The SPLP processing refines the grains and secondary phase significantly in the remelted layer which is reconstructured with the cellular structure and plenty of substructures. The HLP processing also refines the grain and secondary phase but the secondary phases still exhibit array distribution. In addition, the tangled dislocations pile up along the interface of secondary phases. Compared with the as-fabricated sample, the SPLP processing decreases the surface microhardness but the HLP processing increases the surface microhardness, and the Young's elasticity modulus of surface layer is improved by SPLP and HLP processing to 282 ± 5.21 GPa and 304 ± 5.57 GPa, respectively. 翻译
