摘要： Up and Running with AutoCAD 2011: 2D and 3D Drawing and Modeling provides an introduction to the fundamental concepts of AutoCAD. These concepts have been distilled down to basic, easy to understand explanations for the benefit of beginner students. Each chapter explains the new concept or command and why it is important. Readers are given the chance to apply just-learned knowledge to a real-life exercise, drawing, or model. They can also test their knowledge with end-of-chapter quizzes and drawing exercises. The book is organized into three parts: Level 1, Level 2, and Level 3. Level 1 offers a wide breadth of knowledge on many topics. Its chapters comprise the complete essential knowledge set of an intermediate user. Students can then work on, if not necessarily set up and manage, moderate to complex drawings. Level 2 is meant for advanced users who are CAD managers, full-time AutoCAD draftspersons, architects, or self-employed and must do everything themselves. The goal here is depth, and several features not deemed critically important in Level 1 are revisited to explore additional advanced options. Also introduced are advanced topics necessary to set up and manage complex drawings. Level 3 is all about 3D. Solid knowledge of the previous two levels is highly recommended before starting these chapters. The 3D material covers all aspects of AutoCAD solid modeling, including lights and *** away complexities, both real and perceived and reduces AutoCAD to easy-to-understand basic conceptsTeaches only what is essential to operating AutoCAD first, thereby immediately building student confidenceAll basic commands are documented step-by-step, meaning that what the student needs to type in and how AutoCAD responds is all spelled out in discrete and clear steps with screen shots added as neededUsing the author extensive multi-industry knowledge of what is important and widely used in practice versus what is not, the material is presented by immediately imme

摘要： This practice can be used to continuously demonstrate the proficiency of analytical measurement systems that are used for establishing and ensuring the quality of petroleum and petroleum products. Data accrued, using the techniques included in this practice, provide the ability to monitor analytical measurement system precision and bias. These data are useful for updating test methods as well as for indicating areas of potential measurement system improvement. 1.1 This practice covers information for the design and operation of a program to monitor and control ongoing stability and precision and bias performance of selected analytical measurement systems using a collection of generally accepted statistical quality control (SQC) procedures and tools. Note 18212;A complete list of criteria for selecting measurement systems to which this practice should be applied and for determining the frequency at which it should be applied is beyond the scope of this practice. However, some factors to be considered include (1) frequency of use of the analytical measurement system, (2) criticality of the parameter being measured, (3) system stability and precision performance based on historical data, (4) business economics, and (5) regulatory, contractual, or test method requirements. 1.2 This practice is applicable to stable analytical measurement systems that produce results on a continuous numerical scale. 1.3 This practice is applicable to laboratory test methods. 1.4 This practice is applicable to validated process stream analyzers. 1.5 This practice is applicable to monitoring the differences between two analytical measurement systems that purport to measure the same property provided that both systems have been assessed in accordance with the statistical methodology in Practice D6708 and the appropriate bias applied. Note 28212;For validation of univariate process stream analyzers, see also Practice D3764. Note 38212;One or both of the analytical systems in 1.5 can be labora
