"Carbide.c++ 是一款用于开发Symbian系统手机应用的集成开发环境(IDE),基于Eclipse平台构建。它提供了Symbian C++应用程序开发的支持,包括免费的Carbide.c++ Express版本,以及未来计划推出的更多功能的商业版本。Eclipse平台最初由IBM发起,旨在创建一个多平台的Java开发环境,但后来演变成一个工具集成平台,由Eclipse基金会维护,并被Symbian等公司采用。Eclipse的核心在于其可扩展的架构,包含一系列框架,如用户界面、文件系统管理、编辑器、编译器、调试器、版本控制等,便于各种工具的集成。Carbide.c++ 利用了这些特性,为Symbian开发者提供了一体化的开发体验。" 在深入理解Carbide.c++之前,我们首先需要了解它的基石——Eclipse平台。Eclipse是一个开放源代码的项目,始于2001年,由IBM引领的一系列公司共同推出,旨在提供一个跨平台的Java开发环境。随着时间的发展,Eclipse不再局限于Java,而是成为一个通用的软件开发工具集成平台,尤其在Symbian这样的移动操作系统开发领域发挥了重要作用。 Carbide.c++ 是基于Eclipse构建的IDE,专为Symbian系统设计,支持Symbian C++编程语言。免费版本的Carbide.c++ Express是论坛Nokia和UIQ Developer网站上可以下载的工具,它为开发者提供基本的开发功能。除此之外,未来还有计划推出包含更多高级功能的商业版本,这些版本将在正式发布后为开发者带来更多便利。 Eclipse平台的灵活性和可扩展性是Carbide.c++成功的关键。Eclipse的架构允许开发者使用一系列框架来构建特定的开发工具,例如,统一的用户界面框架使得开发环境具有良好的用户体验,文件系统管理框架方便项目管理和文件操作,而文本编辑器框架则提供了源代码编辑能力。此外,Eclipse还提供了编译器框架,用于构建和编译应用程序,调试会话框架帮助开发者进行问题定位,团队编程和版本控制框架则支持协作开发和版本管理。 Carbide.c++ 利用这些框架,为Symbian开发者提供了一个全面的开发解决方案,包括源代码编辑、编译、调试、项目管理等核心功能。通过Eclipse的插件机制,开发者还可以根据需要添加更多的工具和扩展,以适应不断变化的开发需求。 Carbide.c++ 是Symbian开发者的重要工具,它借助Eclipse平台的优势,为Symbian应用开发提供了一站式的开发环境,提升了开发效率和代码质量。随着Symbian系统的广泛应用,Carbide.c++ 在移动设备开发领域扮演了不可或缺的角色。

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
