氮化钒圆盘造粒正交试验研究

VT包芯线粉芯的主要材料是氮化钒,使用中对其粒度有严格要求,在对氮化钒破碎中会产生很多细粉,不能直接使用。为了改善粉末的流动性和提高细粉的利用率,拟定了分级-造粒-干燥工艺对氮化钒粉末进行处理,该工艺流程的核心是造粒。基于氮化钒粉末圆盘造粒的正交试验结果,分析了圆盘转速、粘合剂加入量和原料粒度对干球成粒率和干球落下强度的影响,并通过极差分析和方差分析确定了氮化钒粉末圆盘造粒时较适宜的造粒工艺。

Sensible Media Simulation in an Automobile Application and Human Responses to Sensory Effects

A sensible media simulation system for automobiles is introduced to open up new possibilities for an in‐car entertainment system. In this paper, the system architecture is presented, which includes a virtuality‐to‐reality adaptation scheme. Standard data schemes for context and control information from the International Standard MPEG‐V (ISO/IEC 23005) are introduced to explain the details of data formats, which are interchangeable in the system. A sensible media simulator and the implementation of a sensory device are presented to prove the effectiveness of the proposed system. Finally, a correlation between learning styles and sensory effects (that is, wind and vibration effects) is statistically analyzed using the proposed system. The experiment results show that the level of satisfaction with the sensory effects is unaffected overall by the learning styles of the test subjects. Stimulations by vibration effects, however, generate more satisfaction in people with a high tactile perception level or a low visual perception level.

Retention and distribution of natural antioxidants (α-tocopherol, polyphenols and terpenic acids) after shallow frying of vegetables in virgin olive oil

Potatoes, green peppers, zucchinis and eggplants were shallow fried in virgin olive oil (VOO) according to the Mediterranean traditional culinary practice. Zucchinis and eggplants were also blanketed with wheat flour or batter prior to frying. Polyphenols and hydroxy pentacyclic triterpene acids (HPTAs) were determined by GC/MS, while α-tocopherol was determined by high-performance liquid chromatography. Among 12 polyphenols determined, tyrosol predominated in frying oils and zucchini samples, while chlorogenic acid was the major phenolic species in the other vegetable samples. The triterpene acids maslinic, oleanolic and ursolic were determined in frying oils and fried vegetables, while α-tocopherol was present in all samples. Besides water loss and oil absorption, shallow frying resulted in partial loss of all the antioxidants studied in frying oils and enrichment of fried vegetables with olive oil antioxidants, which was in some extent affected by the type of vegetable fried and the culinary practice followed. The overall retention of the antioxidants in oil and food ranged from 32% to 64% for α-tocopherol, 25% to 70% for polyphenols and 35% to 83% for HPTA. It appears that vegetables fried in VOO provide an additional intake of α-tocopherol, terpenic acids and polyphenols as tyrosol and chlorogenic acid.
