"这篇文档详细介绍了基于Carbide++的S60软件开发流程,适合初学者入门。作者强调这是个人经验总结,旨在分享和积累,不承担商业责任。文中首先介绍了开发环境的搭建,包括安装Carbide_cpp_v2_0、ActivePerl、JDK和SDK,并给出了具体的操作步骤和注意事项,如安装路径的选择和版本的匹配。接着,作者提到了安装完成后可以进行简单的HelloWord程序测试,以验证开发环境是否配置成功。" 详细知识点: 1. Carbide++:Carbide.cpp是一个集成开发环境(IDE),专门用于Symbian S60平台的C++应用开发。它是免费的,且基于Eclipse IDE,能够提供代码编辑、构建和调试等功能。文中提到的Carbide_cpp_v2_0是特定版本,安装时建议使用官方渠道下载,并遵循默认路径安装,以避免调试时出现问题。 2. Perl环境:在S60开发中,Perl是必需的,因为它被用于处理一些自动化任务,如构建脚本。ActivePerl是Perl的一个流行实现,文中指定的版本ActivePerl-5.6.1.635-MSWin32-x86需要与Carbide++兼容,否则可能导致开发问题。 3. JDK(Java Development Kit):JDK是Java编程语言的开发环境,虽然S60开发主要使用C++,但某些工具和过程可能需要Java环境,比如S60 SDK。文中提到的JDK-6u10-rc2-bin-b32-windows-i586-p-12_sep_2008.exe是特定的JDK版本,应确保其与SDK匹配。 4. S60 SDK:SDK(Software Development Kit)包含了开发S60应用程序所需的库、头文件、模拟器和工具。文中提到的SDK同样需要Java环境,且应与JDK版本匹配。安装SDK时,建议选择默认路径,以便于调试。 5. Windows Emulation:在S60开发中,开发者可以使用Windows Emulation模式在Windows环境下调试应用,这需要SDK的支持。文中提到的两个SDK安装是用于Windows Emulation调试的。 6. 测试与调试:安装完所有必要的工具后,可以通过编写和调试简单的HelloWorld程序来检查环境是否配置正确。作者指出,Carbide++首次启动可能会自动安装额外组件,需要重新打开才能开始使用。 7. 开发流程:整体来看,S60的开发流程包括安装开发环境、配置环境变量、创建项目、编写代码、构建和调试。文中提供的步骤是这一流程的基础部分,实际开发中还涉及到更多如项目管理、版本控制、UI设计、性能优化等环节。 通过这篇文档,读者可以了解到S60平台上使用Carbide++进行软件开发的基本步骤,为后续的Symbian C++编程打下基础。同时,也提醒了开发者注意版本兼容性和安装顺序,这对于避免常见错误至关重要。

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
