简介：对于SMT工艺技术人员来说，一个重要的工作就是从CAD设计系统中获取必要的特征数据，经过相应的整理、转换，使之能成为符合要求的格式。在数据准备过程中发现了一些问题，例如CAD设计系统和SMT设备定义的元件角度不一样等。为解决这些问题，文中开发了数据准备系统DPS，它能自动检查并修正元件角度。此外，DPS能处理多种格式的CAD数据，大幅度提高生产效率，证明了本解决方案的优越性和高效性。文中详细介绍了DPS软件的设计与开发中的思想、方法和经验，并着重探讨了坐标数据的处理和转换。

简介：在转播中央电视台《新闻联播》过程中采取多重备份措施十分必要。本文以LEITCH公司的DPS575为例,介绍在嵌入音频的数字播出系统中,如何利用DPS575本身所具有的功能特性实现转播中的多重自动备份。此方法经过我们实践应用,效果良好。

简介：新福克斯在我国上市后曾连续占据轿车市场月销量冠军,这与其性价比、配置、外观等各项指标都极具竞争力有关。但客户对新福克斯的投诉量也连续数月保持较为尴尬的同步增长,其中变速器、发动机等方面确实呈现不同程度的质量问题。本文主要论述新福克斯的双离合变速器控制原理和故障分析以及检修方案。

简介：全面的抽象A但是称为DPS(数据处理系统)的simple-to-use软件包裹被开发了执行在试验性的设计，统计和数据采矿使用的标准数字分析和操作的一个范围。这个程序在标准Windows计算机上跑。许多函数对特定昆虫学并且另外的生物研究并且没在标准统计软件被发现。这篇论文在昆虫学介绍DPS的应用程序给试验性的设计，统计分析和数据采矿。

简介：AbstractThe aim of this study was to evaluate the performance of an assay using dried plasma spot (DPS) and dried blood spot (DBS) samples for the serological detection of anti-hepatitis C virus (HCV) antibodies. Between January and July 2019, plasma, DPS and DBS specimens were collected from individuals at high-risk for HCV infection. Samples were tested for anti-HCV by ELISA, and the performance of DPS and DBS specimens was examined using results from the plasma testing, as the standard. Blood samples were collected from 329 persons, including 129 men who have sex with men and 200 intravenous drug users. Results from the plasma testing indicated that 118 samples (59.0%) were HCV positive. Data from the DPS sample testing showed sensitivity as 99.2% (95% confidence interval [CI]: 0.95-1.00) and specificity as 100% (95% CI: 0.98-1.00) for HCV detection, with Kappa of 99.3% (95% CI: 0.98-1.00) while in DBS sample testing the sensitivity as 98.3% (95% CI: 0.93-1.00) and specificity as 100% (95% CI: 0.98-1.00), with Kappa of 98.7% (95% CI: 0.97-1.00), respectively. Spearman’s correlation coefficients for the comparisons between plasma and DPS specimen, plasma and DBS specimens, DPS and DBS specimens were 0.857, 0.750, and 0.739, respectively. Compared with the results in plasma, 1 sample was not detected using the DPS specimens, and 2 samples were failed for the positive detection, using the DBS specimens. Both DPS and DBS samples were promising alternatives to plasma, for the detection of anti-HCV antibodies.

简介：摘要对于特高压直流输电工程而言，换流器解锁顺序控制分为正常极解锁顺序控制以及不完整极运行转入完整极运行解锁方式。正常极解锁时，不论该极处于完整极或不完整极运行接线，在两站投入绝对最小滤波器后，极正常启动时，均为逆变侧先解锁建立逆变侧直流电压，整流侧后解锁升电压并产生直流电流。本文以应用许继DPS-3000平台的±800kV的广固换流站为例，从阀控系统跳闸、极控系统跳闸两个方面，分析特高压换流站解闭锁顺序控制。
