提问者采纳
V1mL、0.2mol/L&Na2SO4溶液中SO42-的物质的量=V1×10-3L×0.2mol/L=2V1×10-4mol，V2mL、0.1mol/L&Fe2（SO4）3溶液中SO42-的物质的量=V2×10-3L×0.1mol/L×3=3V2×10-4mol，则混合后溶液中SO42-的物质的量浓度=1×10?4mol+3V2×10?4mol(V1+V2)×10?3L=1+0.3V2V1+V2mol/L=（0.2+2V1+V2）mol/L，由于V1大于V2，故0＜2V1+V2＜0.05，故混合后0.2mol/L＜c（SO42-）＜0.25mol/L，故选A．

引用Supported 3D Formats:引用Simlab Composer System Requirements
* Windows 7
* Windows XP
* Windows Vista
* Windows 2003 Server Edition引用New tools in version 2.1 include:
* Viewing the environment image (HDR), and the background image (back plate) from inside Composer, which takes out the guess work of placing the 3D scene to appear in a good position in the environment, and to make it match the background image.
* Simlab Composer is easily mastered
* Rotating the environment image: this capability enables the user to get optimal lighting from the environment image.
* Render Preview: using render preview the user will be able to make quick adjustments on selected materials, brightness and other rendering parameters, without the need to wait for creating the full scale image.
* Simlab Composer is easily mastered
* Adding alphas support to the created images: in addition to jpeg output format, the user can select TIFF which includes alpha channel information. This will enable the user to use images rendered in SimLab Composer with other image processing application to create stunning effects.
* Adding ground reflection
* Adding support for importing and exporting material libraries: starting from version 2.1 users will be able to easily exchange materials they created in SimLab Composer. A material library can be exported as a single mlb file which includes material definitions, texture images used by the library, and preview images of the materials.
The recipient of the mlb file can import the contents of the material library by using the import material library button.Creating 3D PDF filesSimLab Composer automatically exports the object tree to the 3D PDF files it creates. Version 2.1 provides the user with tools to orga changes made to the objet tree in SimLab Composer are automatically reflected in the generated 3D PDF file. The recipient of the file can use the organized tree to hide/show different parts of the model to have a better understanding of the 3D scene.Building 3D ScenesVersion 2.1 provides the user with a new tool to break geometry, which automatically breaks unconnected parts in a 3D this functionality will make many 3D models imported in flat file formats usable for building 3D Scenes.Import\Export enhancementsDWG/DXF import is now supported on Mac and Windows.Version 2.1 offers significantly faster import time for step files.Simlab 的 Composer 能够帮助创建高级3D场景，允许用户整合来自不同平台/格式的几何物体，以方便快速地创建各种场景。允许的平台/格式包括： Rhino, IGES, STEP, Solidwords, SketchUp, 3DXML, FBX, 3DS, OBJ, U3D, 和 3D PDF。这个特性能够极大的帮助开发者互动地创建高级3D场景模型, 并借助COLLADA实现资源共享, 以及通过PDF 3D 格式维护场景创建的组合结构。功能特性：*易于操作控制*释放CAD模型*多操作系统支持*正确的工具来创建你的场景*分享你的场景*树状功能*复制和创建示例*场景打包*纹理生成*3D文字*坏模型修复Simlab Composer CapabilitiesImport/ExportSimLab composer supports importing 3D models from many of the standard file formats, including: SketchUp, Rhino, STEP, IGES, Collada, 3D PDF, 3D XML, FBX, Obj, 3DS, DXF, U3D, STL, DWG , and SolidWorks.3D models and scenes can be exported to the following files formats, OBJ, FBX, Collada, STL, U3D, BIP and OSGPlease click here for a full list of supported 3D file formatsBuilding 3D ScenesSimLab Composer provides the user with all the needed tools to build 3D senses from existing models. In addition to the draggers found in modern 3D applications to place models in the scene, SimLab Composer offers unique tools like snap to object and snap to ground to make building 3D scenes intuitive and fast.SimLab Composer maintains the assembly structure of imported 3D models, this enable the user to select the level to work on (face, body, part, subassembly or assembly).For models with no texture coordinates, SimLab Composer gives the user the needed tools to generate texture coordinates. Simlab Composer also provides the user with the ability to add 3D text to any scene.Creating 3D PDF files
* Sample 3D PDF Output from Simlab Composer3D Scenes created in SimLab Composer, can be exported as a 3D PDF files, a 3D PDF file is a PDF file (that can be opened using a free version of Acrobat reader), which includes 3D Data.The recipient of the file will be able to view, rotate, and interact with the 3D scene.3D PDF was designed to be very easy to use for none technical users.SimLab Composer enables the user to customize the generated 3D PDf file, customizations supported include:
* Selecting the page size and margins
* Selecting optional page background (image and music)
* Adding Header/Footer text
* Selecting the 3D background
* Adding optional automatic camera animation
* Selecting rendering styles from solid, Illustration, transparent, and other styles
* Selecting the light system from CAD Optimized, night, highlight and other light systemsPlease click here for sample 3D PDF files created using SimLab ComposerRendering Photorealistic Images
* Sample 3D PDF Output from Simlab ComposerSimLab Composer includes a licensed version of Luxion Renderer, a high quality, accurate and extremely fast global illumination renderer, which enables the user to create high quality photorealistic images quickly.
* Simlab Composer Material SamplesAssigning materials can be done by dragging materials from the material library supplied with SimLab Composer and dropping them on the 3D objects. http://www./Simlabimages/Simlab-Composer/simlab-composer-screenshot1b.jpg
