"紫荆花"象征着亲情、团结、和睦,因此也成为香港的象征,称其为市花。美丽的紫荆花,经历了历史的血泪,百年的风雨,和那怒放的紫荆花树一起向我们尽情展现那侠骨柔情之美。1982年,香港紫荆花制漆就成立于那芬芳美丽、朝气蓬勃、光彩夺目的香港。随后分别在上海、成都、深圳、惠阳、汕头及东莞建有生产基地,以先进的生产技术、科学的管理模式,迅速在中、港、澳三地崛起。多年来紫荆花涂料一直被香港房屋选用为指定品,广泛应用于社会各类大型场所。秉承多年累积的经验,借助于"漆艺坊"的成功推行,紫荆花建筑涂料在中国内地亦大放异彩。踏入千禧年,蓄势待发的重工业涂料悄然推向市场,迅即承接了机场、大桥、码头、集装箱、化工基地等大型项目,发展重工业涂料将是紫荆花打造化工王国的另一里程碑。经历整个隆冬的酝酿,春的气息终于冲破凝固的寒冬,打破沉闷无声的落雪,清新的空气弥漫遍及每一个角落。伴随着2008年春的气息,我们的心情也变化得像春季的花朵一样绚烂。带着这份好心情,我有幸走访了香港紫荆花制漆(大中华)有限公司,并和该公司市场总监叶钧有一席交谈。  相似文献

硬度是衡量超硬材料烧结体的主要特性之一.然而目前国内外还没有超硬材料烧结体硬度测量的统一的标准.文章通过硬度计测量标准块的硬度值总结如下:施加相同力而采用不同形状的压头所得结果不同,采用相同的压头而施加不同的力所得结果也不一样;随着施加负荷的增大,压痕周围产生的破碎形变也在增大,这将影响测量值的准确性.因此,压头的形状和所施加的负荷是影响硬度值的一个重要因素.通过分析得知,在测试中应采用努普压头并且施加小负荷的力.[1,3]  相似文献

Carotenoids can be effective singlet oxygen quenchers and inhibit free-radical induced lipid peroxidation. A remarkable property of β-carotene ( 1a ) is the change from an antioxidant to a prooxidant depending on oxygen pressure and concentration. In the present study a considerable number of carotenoids ( 1a , 2c , 2d , 2e , 3a , 4a , 5a , 6a , 7a , 8a , 8h , 8i , 8j , 9f , 10a , 11a , 12g ) was investigated using two independent approaches: 1. Comparison of their effects on inhibition of the free-radical oxidation of methyl linoleate, and 2. The direct study of the effect of oxygen partial pressure upon their rates of oxidation. It is shown that some carotenoids ( 7a , 8a ) are even more effective than the well-known compounds β-carotene ( 1a ) and astaxanthin ( 5a ) and are powerful antioxidants without any prooxidative property. Different carotenoids display different behaviour depending on chain length and end groups. The influence of these functional groups on the antioxidative reactivity is discussed.  相似文献

Using a chronically placed jugular catheter and a silver electrode, it was possible to monitor short-term changes in the plasma concentration of cortisol and catecholamine in the marsupial sugar glider (Petaurus breviceps) and to monitor both heart and respiration rates. Males judged to be low in the social hierarchy of a particular group were exposed to the whole-body odor of a dominant male from the same social group, a foreign dominant male, or a castrate male. While there was no evidence of a change in any of the physiological parameters when a male was exposed to either a castrate male or a female, a rapid increase occurred in heart rate and plasma concentrations of cortisol, glucose and catecholamine when the donor was a dominant male from the same or a different social group.  相似文献

Examination of the receptive field structure of the retina suggested looking at small graphic figures of special forms. The luminance distribution called the “Mexican hat function” was approximated by a black dot with a small white dot at its center, called a “tip,” and the inverse function was approximated by a white dot with a small black dot at its center, called a “pit.” Such figures were given the generic name “tippit.” On a dark‐blue ground, tips looked yellow, and on a bright‐yellow ground, pits looked blue. Similarly, a black line with a white center, on a blue ground, and a white line with a black center, on a yellow ground, elicited these effects. On yellow and blue grounds, simple, small colored dots looked more like the color of the ground than when seen as large spots on a neutral gray ground, an effect here called “microspreading.” This effect may be attributable to scattering and blurring, but these processes do not account for the tippit effects. The visual system exaggerates contrast between a large spot and ground, and diminishes contrast between a small dot and ground, but exhibits neither effect on a figure of some intermediate size. Chromatic pit lines exhibit effects obeying laws of additive mixture. It appears that perceptions of these effects are normally repressed. No causal link was sought or established between receptive field theory and the observed effects. © 2003 Wiley Periodicals, Inc.

气固流化床固体浓度分布的冷模研究   总被引:1,自引:0,他引:1  
在内径0.284 m、高6.0 m的气固流化床冷模装置中进行了气固流化实验,采用PC6 D型颗粒浓度测试仪检测固体浓度. 分别采用枝条型(开孔率a=5‰和2.5‰)和环形(a=5‰)气体分布器,以直径154~180 mm、密度2550 kg/m3的砂子为颗粒,在静床高H0=0.6~1.5 m、表观气速u=0.3~0.6 m/s的情况下,考察了时均固体浓度1-e在空间的分布. 结果表明,增加u使密相区的1-e减小,分布器形状对1-e影响不大. 采用较低a的分布器时1-e的变化较大,且其值均较低. H0=0.6 m, 轴向位置H=0.4 m, u=0.3 m/s, 径向位置r=0~0.142 m时,1-e由0.410上升到0.494;H0=0.6 m, H=0.4~0.95 m, u=0.3 m/s, r=0时,1-e从0.410减小到0;H0=1.5 m, H=0.4~1.3 m, u=0.3 m/s, r=0时,1-e从0.397先下降到0.372,再上升到0.424,最后下降到0.328.  相似文献

Chlorophyll pigments present in canola seed, meal and crude and degummed oils were analyzed by high-performance liquid chromatography (HPLC) with a fluorescence detector. Chlorophylls a and b, low levels of pheophytin a, and occasionally traces of pheophorbide and its methyl ester were present in canola seed. Meals and oils contained magnesium-deficient chlorophyll pigments such as pheophorbide a, methylpheophorbide a, pheophytins a and b, and pyropheophytins a and b but not chlorophyll a or b. The amounts of chlorophyll pigments were oil > seed >> meal. Both crude and degummed oils contained pheophytin a and pyropheophytin a as main components, but the ratio of pyropheophytin a to pheophytin a was markedly higher in degummed oils. No pheophorbides were detected in degummed oils. These results suggest that oil processing steps such as extraction and degumming affect the composition of chlorophyll pigments.

国内外己内酰胺生产现状及市场分析   总被引:2,自引:0,他引:2  
世界上最大的5家己内酰胺生产商是德国BASF公司,生产能力为55.5万T/a;荷兰DSM公司,生产能力为42.0万t/a;美国Allied-Signal公司,生产能力为32.7万t/a;日本宇部兴产公司,生产能力为26.8万t/a;日本东丽公司,生产能力为17.0万t/a。这5家公司的已内酰胺生产能力合计为174万t/a,约占世界总产量的50%。中国目前有4套己内酰胺生产装置,岳阳巴陵鹰山石化厂,2000年生产能力为7万t/a;南京东方公司,生产能力为6万t/a;石家庄化纤公司,生产能力为5万t/a;浙江巨化公司锦纶厂,生产能力为0.45万t/a,全国合计年生产能力为18.45万t/a。国外己内酰胺的主要消费领域为纤维、工程塑料和食品包装膜;国内已内酰胺的主要消费领域为帘子布、民用丝、工程塑料,所占比例分别为70%、28%、2%。国内己内酰胺需求一直大于国内产量,但由于技术力量薄弱、资金有限及下游产品结构不合理等原因制约了己内酰胺的应用,目前国内的已内酰胺主要应用在中低档产品中,高档产品所需己内酰胺仍要依靠进口。  相似文献

This article poses and discusses a maximization problem: for a given chromaticity, and in a given illumination, how light a fluorescent color is possible. The article does not present a solution, but does offer a conjecture that for many illuminants and many chromaticities the greatest lightness is achieved by a simple form of bispectral function. The output is in two points plus a tail, so we call it a “PPT” function. © 2007 Wiley Periodicals, Inc. Col Res Appl, 32, 85 – 91, 2007  相似文献

A stress distribution model for a liquid-solid circulating moving bed reactor that consists of a bottom reaction chamber, a top regeneration chamber, a coupling standpipe, a particle transportation system, and a bottom standpipe is established based on the equations of continuity and momentum balance. Simulations show that the stress concentration regions are at the bottom of the regeneration chamber and the coupling standpipe. To reduce the maximal stress and increase the operation flexibility in a reactor for the 2000-ton-per-year production of linear alkylbenzene, the regeneration chamber should have a low height-to-radius ratio (about 9), a suitable half-conical angle between 28° and 35°, and standpipe radius of about 0.05 m.  相似文献
