Effect of 24-h severe energy restriction on appetite regulation and ad libitum energy intake in lean men and women
appetite hormones energy balance calorie restriction
2018/12/19
Background: Intermittent severe energy restriction (SER) can induce substantial weight loss, but the appetite regulatory responses to SER are unknown and may dictate long-term dietary adherence.
Relation between mealtime distribution of protein intake and lean mass loss in free-living older adults of the NuAge study
dietary protein aging lean mass muscle mass sarcopenia elderly nutrition
2018/12/14
Background: Studies have shown that an even protein intake distribution across meals increased 24-h muscle protein synthesis in young adults compared with a skewed intake. Whether this short-term resu...

Fully formulated lean NOx trap (LNT) catalysts of the type Pt/Rh/BaO/Al2O3 were prepared with and without incorporation of CeO2-ZrO2 in the washcoat, and their NOx reduction behavior was evaluated in ...
混氢对稀燃汽油机怠速性能的影响试验（Effect of Hydrogen Enrichment on the Performance of a Lean-burn Gasoline Engine at Idle）
汽油机 氢气 稀燃 怠速
2010/12/29
在一台安装了氢气电控喷射系统的汽油机上，通过调整喷氢脉宽，研究了氢气占进气体积分数为3%时混氢对稀燃汽油机怠速燃烧与排放性能的影响。试验结果表明，混氢后发动机指示热效率提高；火焰发展期与快速燃烧持续期缩短；过量空气系数为1.3时，平均指示有效压力的循环变动系数由原机的33.9%降低至混氢后的13.7%；稀燃条件下，进气混氢有利于改善汽油机怠速时的HC、CO与NOx排放。
Lean海滩椅由丹麦设计师Hans Sandgren Jakobsen于2008年为丹麦Skagerak Denmark A/S公司设计。这款海滩椅仅由两块板组成，当它折叠起来时占用的空间真是少之又少，便捷的折叠展开方式和轻便的体形使Lean椅极易于携带。Lean椅在2008年于丹麦举办的Formland设计节（Formland design fair）上获得了Formland设计奖，评委会给...

Many companies are implementing lean manufacturing concept in order to
remain competitive and sustainable, however, not many of them are successful in the
process due to various reasons. Communica...
A traditional lean transformation process does not validate the future state
before implementation, relying instead on a series of iterations to modify the system until
performance is satisfactory...

基于计算机视觉和神经网络的牛肉颜色自动分级（Automatic Color Grading of Beef Lean Tissue Based on BP Neural Network and Computer Vision）
牛肉 颜色 分级 神经网络
2009/5/22
将采集的牛胴体眼肌切面图像人工确定其颜色等级，然后通过计算机图像处理方法，分割出肌肉区域并提取出其在RGB和HIS颜色空间的颜色特征参数。设计一个以牛肉的颜色特征参数为输入、牛肉的颜色等级为输出的BP神经网络模型，通过训练，确定模型的结构参数，用测试样本对该模型进行验证。结果显示，用该模型进行牛肉颜色等级预测的正确率可达95%，耗时仅0.25s。表明利用所设计的模型可以对牛肉的颜色等级进行快速、准...
燃烧室结构对稀燃天然气发动机性能的影响（Influence of the Combustion Chamber Structure on the Lean Burn CNG Engine Performance）
天然气发动机 燃烧室 稀薄燃烧
2009/5/22
阐述了稀燃天然气发动机缸内不同气体运动及其产生机理，分析了缸内气体运动对发动机燃烧过程的影响。针对稀燃天然气发动机的燃烧过程,设计了不同结构形状和尺寸的燃烧室,并分别通过数值模拟和试验方法，就不同结构的燃烧室对天然气发动机性能的影响进行了研究。结果显示，产生湍流强度大的燃烧室燃烧速度快，动力性和经济性较好，而NOx排放量也较大。
