摘要:
Performance evaluation of computed tomography is not significant in the Republic of Cameroon in general and more particularly in the city of Yaoundé. Therefore, this work aimed to analyze image performances of 05 CT scanners in 05 medical facilities in the city of Yaoundé, by using the Catphan 700 phantom and test procedures of the Atomic Energy Agency. Five quality control tests were performed on each CT-Scanner. All the CT scanners evaluated showed good results and were not disapproved in three of the five tests performed. The difference between the measured spatial resolution for each of the five CT scanners and the spatial resolution specified by the manufacturer was very high. The low contrast resolution of four of the five CT scanners was found low when compared to the low contrast resolution specified by the manufacturers.

摘要:
随着经济的发展,中央数字电视覆盖工程也得到了不断的进步。广电的不断发展,现在规划方案中,发射机数量也在不断增多,这也就意味着广电要在事实上占领700 MHz频段了。文章通过研究广电700 MHz频段相关技术要求,分析了广电700 MHz频段布置基础,并且根据研究制定了关于广电700 MHz频段的可行性报告,还分析了广电700 MHz频段的试用测试效果。

摘要:
通过固溶强化、细晶强化和沉淀强化的有效结合,设计了一种700 MPa级C-Si-Mn-V-Ti钢,进行了工业试制和产品的拉伸性能、冲击性能检验;利用金相显微镜和扫描电镜观察了连铸坯铸态组织、H型钢轧态组织和冲击断口。结果表明连铸坯枝晶细化,轧材组织为铁素体和珠光体,冲击断口为典型的韧性断口。

摘要:
Coal quality analysis and thermogravimetric analysis of No.6 boiler of Fengcheng Phase II Power Plant were researched, and 12 different sub-warehouses blending programs for the representative coal were selected, and the boiler thermal efficiency tests were carded out. The impacts of the boiler fly ash combustible, the slag combustible, smoke damage in the trial to the boilers efficiency were analyzed, the optimum co-firing of coal blending were advanced, and the scientific basis for the boiler combustion optimization adjustment were provided.%对江西赣能股份丰城二期发电厂#6炉入炉煤进行煤质分析及热重分析后,选取具有代表性的煤种进行12种不同的分仓配煤方案,对锅炉热效率测试。分析配煤试验中锅炉飞灰可燃物、炉渣可燃物、排烟损失等因素对锅炉效率的影响,得出最佳的配煤掺烧方案,为锅炉燃烧优化调整提供科学依据。
