Ford公司针对整个皮卡和轻型商用车市场设计开发了一款新型柴油机,即6.7 L Power Stroke?V8涡轮增压柴油机,产品代号"Scorpion"。新型柴油机燃烧系统的设计包括活塞燃烧室、涡流水平、喷嘴喷孔数、燃油喷射角度、喷嘴尖端突出量、喷嘴液压流量、喷孔锥度等。尽管这些参数都可以通过广泛的硬件测试得以确定,但仍利用三维计算流体动力学（CFd）研究方法快速筛选出2个活塞燃烧室方案,并评估其对其他参数的敏感性。为2个最有开发潜力的活塞燃烧室方案构建了单缸发动机,以对其余的燃烧系统参数进行优化。用一维CFd模型设置三维CFd在进气门关闭时的边界条件,后者被用于仿真的封闭循环部分。选择发动机测功器认证的关键工况C100,评估这些参数的每种组合在气缸内有限可用氧的利用好坏。开发了一种分数因子设计试验（doE）方法,用于评估每个燃烧室方案的3种形状参数、2种涡流水平,以及3种燃油喷射角度。基于多目标优化,选定2种燃烧室形状,力求尽可能减少燃油耗,以及氮氧化物和碳烟排放。采用doE方法可评估对其他参数变化的敏感性,这对于考虑生产中各种变化的可靠性是非常重要的。用三维CFd得出的混合结构分析结果证明,它有助于解释某些趋势。每个活塞燃烧室都被布置在单缸发动机机体中,并准备了具有2种不同涡流水平的气缸盖。制造了1套喷油器,用于改变喷油器喷孔数、燃油喷射角度、液压流量和喷孔锥度。对于每个喷油器,采用不同厚度的铜垫圈来微调喷嘴突出量。对于每个硬件的组合,在4种不同工况下（C100、A100、A25、发动机转速1 500 r/min且平均有效压力0.3 MPa）进行了废气再循环的扫气分析,以全面评估排放和燃油经济性。对于发动机测功器认证的排放达标,2个较高的负荷点是关键的;而对于典型的行驶燃油经济性和底盘测功器认证的排放达标,2个较低的负荷点则是关键的。废气再循环扫气分析证明,它们非常有助于确定新型6.7 L Power Stroke V8涡轮增压柴油机燃烧系统的参数选择。电热塞被选定为主要的冷起动辅助装置。为了找到可以提高冷起动能力、气缸盖强度和电热塞耐久性的最佳位置,进行了CFd研究。在多缸发动机上,对建议的位置和插入深度进行了测试,以验证其功能,并为确定最终的电热塞位置提供数据。生产时采用的位置在气门鼻梁区以外,既最大限度地提高了雾化燃油与电热塞的互相作用,又最大限度地降低了液滴对电热塞的碰撞。

Acta Metallurgica Sinica(English Letters) 2000年第2期13卷 832-842页

作者： d. Jin E. d. dominik R. V. Kolarik II J. E. ives and E. B. damm (The Timken Company, 1835 dueber Avenue, S.W., Canton, Ohio 44706-0932, U.S.A.)

An integrated mathematical model to simulate seamless tube rolling processes has been developed at The Timken Company. The model is capable of simulating the thermal, deformation and microstructure evolution in the piercing, elongating and reducing/sizing and the austenite decomposition in the mill annealing and cooling operations. Finite difference schemes are employed to model cooling, reducing/sizing and stretch reducing, and finite-element schemes are employed to simulate piercing and elongating. The model predicts the thermal history, deformation, rolling load, torque, recrystallization and grain growth in hot tube rolling, austenite decomposition in cooling or annealing, and the final structure-properties. In this paper mathematical models which are employed to describe the thermal, deformation and microstructure evolution along with the modeling results are presented. The developed 'tube rolling mill in the computer' provides a powerful tool for engineers for product and process development, process control, process optimization and quality control.

Social networks sites（SNS） have increased in number and popularity this last decade. A recent report of china internet network and information centre has shown that an average of thirtyone per cent of users of SNS drop usage after adoption indication a timely concern of SNS providers in sustaining their platform. The current study proposed a research model based on selfregulation theory of Bagozzi to investigate the impact of SNS platform quality and pleasure on user-satisfaction and how the latter influence user-loyalty. The model was tested with survey data from Weibo users. The result has shown that are significantly related to user-satisfaction and satisfaction strongly associated with user-loyalty.

This study focuses on enhancing the value of agricultural products by developing a process to produce wine from cashew apples enriched with extracts from Hibiscus sabdariffa. The formulation consisted of a blend of cashew apple juice and Hibiscus calyxes in a ratio of 90:10 (w/w). The Hibiscus calyxes were added at three different stages: before, during, and after fermentation. The physico-chemical analysis of the resulting wines revealed a pH range of 3.073 ± 0.005 to 3.583 ± 0.015 and acidity levels ranging from 4.018 ± 0.028 to 5.628 ± 0.059 g/L. The alcoholic strength ranged from 13.54% ± 0.036% to 13.86% ± 0.04%, with a soluble dry extract of 7.2 ± 0.25 to 8.1 ± 0.28 °B. Regardless of the stage of Hibiscus calyx addition, the fermentation kinetics and physico-chemical parameters met the standards set for wines.

This study aimed to investigate the effect of yam flour substitution (dioscorea alata L.) and moringa powder in wheat bread on glycemic response. Glycemic index (GI) and glycemic load (GL) of pieces of bread were determined. A mixture plan design was used to determine the optimal formulation of bread made of yam flour, wheat flour and moringa powder. The mixture of 79.4% soft wheat flour, 20% yam flour and 0.6% moringa leaves powder has a good potential in bread preparation and was used in this study. 100% wheat bread was used as control. Postprandial blood glucose response (glycemic response) was evaluated with the glucose used as a reference food. Blood glucose responses were measured at different intervals for 2 hours. The results indicated that composite bread had low GI and GL values than wheat bread. Values are GI = 80 and GL = 61.2 for wheat bread and GI = 37.78 and GL = 29.65 for the composite bread. This study demonstrated that the inclusion of yam flour of moringa leaves powder in bread production might not pose a threat to blood glucose response compared to wheat bread. These pieces of bread could be included easily in diabetics’ and non-diabetics diet.

Objective: To quantify more reliably the benefits and risks of monoamine oxidase type B inhibitors (MAOBIs) in early Parkinsons disease. data sources: Searches of the Cochrane Library, Medline, Embase, PubMed, and We b of Science for years 1966-2003, plus major journals in the field, abstract bo oks, and proceedings of meetings, for randomised trials comparing MAOBIs with pl acebo or levodopa. data extraction: Available data on mortality, motor complicat ions, side effects, treatment compliance, and clinician rated disability (for ex ample, unified Par kinsons disease rating scale) were extracted from 17 trial s and combined using standard meta analytic methods. Results: No significant di fference in mortality existed between patients on MAOBIs and control patients (o dds ratio 1.13, 95%confidence interval 0.94 to 1.34; P=0.2). Patients randomise d to MAOBIs had significantly better total scores, motor scores, and activities of daily living scores on the unified Parkinsons disease rating scale at three months compared with patients taking placebo; they were also less likely to nee d additional levodopa (0.57, 0.48 to 0.67; P develop motor fluc tuations (0.75, 0.59 to 0.95; P = 0.02). No difference existed between the two g roups in the incidence of side effects or withdrawal of patients. Conclusions: M AOBIs reduce disability, the need for levodopa, and the incidence of motor fluct uations, without substantial side effects or increased mortality. However, becau se few trials have compared MAOBIs with other antiparkinsonian drugs, uncertaint y remains about the relative benefits and risks of MAOBIs. Further large, long t erm comparative trials that include patient rated quality of life measures are n eeded.
