Objective： To investigate the effects of Chang-ChuI-Eui-Ee-ln-Tang （苍术薏苡仁汤, CCEET）, modified CCEET （MCCEET）, and Semen Coicis （SC, a major component of CCEET） on energy and glucose homeostasis. The possible mechanism of action of CCEET was also determined. Methods： A total of 100 Sprague Dawley female rats were randomly assigned to 5 groups, with 20 in each group. Rats in 4 groups were fed with a high fat diet supplementation （2 g/kg body weight）, and water extracts of CCEET, MCCEET, SC, and cellulose （negative control）, respectively. The last group was fed with a low-fat diet as a positive control. Results： CCEET and MCCEET decreased body weight and body fat （mesenteric and retroperitoneal fat） more than SC. This decrease was due to decreased energy intake and increased energy expenditure and fat oxidation. The improvement in energy homeostasis was associated with the enhancement of the hypothalamic leptin signalling pathway involving potentiating the phosphorylation of the signal transducer and activator of transcription-3, as well as attenuating the phosphorylation of 5＇ adenosine monophosphate-activated protein kinase （AMPK）. Both CCEET and MCCEET improved glucose tolerance without changing serum insulin levels during an oral glucose tolerance test but MCCEET had a better effect than CCEET. Conclusions： Both CCEET and MCCEET safely exerted anti-obesity effects by enhancing energy balance in female rats with diet-induced obesity; MCCEET showed a better effect on glucose homeostasis.

Low-cost TiZr-base bulk metallic glasses （BMGs）（Ti36.1Zr33.2Ni5.8Be24.9）100-xCux （x=5, 7 and g） with a maximum size of over 50 mm in diameter were developed by optimizing the alloy composition. The idea is initiated by selecting a particular microstructure comprising primary β-Ti dendrite and amorphous phase. Afterwards, based on this composition of amorphous phase, a class of TiZr-base bulk metallic glasses was designed step by step to reach the optimum composition range. The glass transition temperature （Tg）, initial crystallization temperature （Tx） and width of supercooled region （AT） of （***33.2Nis.8Be24.9）91Cu9 BMG are 611, 055 and 44 K, respectively. The （Ti36.1Zr33.2Ni5.8Be24.9）91Cu9 BMG exhibits low density of 5.541 g·cm-3 and high compressive fracture strength of 1800 MPa, which promises the potential application as structural materials.

为了提升热泵采暖系统的运行能效,提出一种强制对流散热器作为热泵的室内末端。以某典型办公室为例,在实测研究的基础上,采用CFD模拟该散热器营造的室内热环境状况,并在考虑热舒适性约束的前提下,以最大化节能潜力为优化目标,对强制送风速度和散热器表面温度进行同步优化。研究发现,送风速度和表面温度对室内热环境的影响具有耦合性。为避免人体吹风感,可在散热器出风口处安装导流罩。优化获得的送风速度为1.2~1.9 m/s,对应的散热器表面温度为41~45℃,表明该技术可带来较为显著的节能效益。
