曹冲是曹操25个儿子中的一个,比不了才高八斗的曹植,斗不过深谙权谋的曹丕,亲生之母环夫人也不给力,名不见经传不说,似乎也不怎么得宠,所以,接曹操的班,角逐曹家班的CEO,曹冲实在没啥优势可言。才情不够,关系不足,那就比体力吧。然而现实情况是:曹冲小曹植4岁,曹植小曹丕5岁,据此,曹冲要比曹丕整整小9岁——如此一番比较,曹冲已然几近全线完败。  相似文献

宜兴紫砂壶与其有6000千多年的陶瓷历史相比较,她的出现略显迟缓,仅有500多年的历史。但纵观宜兴紫砂继承传统,立足创新,新品新容层出不穷,障了以其得天独厚的材质,千姿百态的造型,独树一帜的工艺,高雅脱俗的文化韵味独步千秋外,还与历代艺人展开想象的翅膀,励志创新,洗新革面,汲江南地理习俗、文人沃土,集天时地利人和之优势,灵活掌握运用“质、形、神、艺”等手段,在想象中孜孜追求,在想象中不断求新,在想象中不断开拓,在想象中不断磨炼所分不开的。一个艺人,如果不能充分展开想象的翅膀,要想成功创新一把新壶是很难取得成功的。  相似文献

粉彩雪景是陶瓷彩绘中的特种工艺,他的创始人是民国时期“珠山八友”之一的何许人。他的这一技法一直流传至今,发展成为具有景德镇特色的一个瓷绘体系。然而,任何一种事物都有其发展与停滞时期,一门艺术的历史越长,传统越浑厚,必然会形成一套程式化的模式,后学者极易被其束缚,粉彩雪景装饰也是一门艺术,也必然会出现这种情况,时代在前进,社会在变化,人的观念也在不断地变化、提高,所以,粉彩雪景也应顺应时代的步伐,与时俱进,勇于创新。  相似文献

橡胶制品硫化过程中,不可避免地会在模具内表面产生结垢现象,造成模具内表面不光滑而影响橡胶制品外观,一般工业橡胶制品加工厂清除模具污垢的方法,多采用酸洗或碱洗,效果不够理想,轮胎外胎硫化模具除垢,国内一直采用小刀刮,砂纸磨,这样落后的原始方法,其劳动度大,效果不理相,尤其在花纹深处的轮廓部位难以清洗,久而久之,造成模具字迹模糊,陈垢结疤,影响轮胎表面的光洁度。  相似文献

Despite its industrial importance, the subject of freeze-thaw (F/T) stability of latex coatings has not been studied extensively. There is also a lack of fundamental understanding about the process and the mechanisms through which a coating becomes destabilized. High pressure (2100 bar) freezing fixes the state of water-suspended particles of polymer binder and inorganic pigments without the growth of ice crystals during freezing that produce artifacts in direct imaging scanning electron microscopy (SEM) of fracture surfaces of frozen coatings. We show that by incorporating copolymerizable functional monomers, it is possible to achieve F/T stability in polymer latexes and in low-VOC paints, as judged by the microstructures revealed by the cryogenic SEM technique. Particle coalescence as well as pigment segregation in F/T unstable systems are visualized. In order to achieve F/T stability in paints, latex particles must not flocculate and should provide protection to inorganic pigment and extender particles. Because of the unique capabilities of the cryogenic SEM, we are able to separate the effects of freezing and thawing, and study the influence of the rate of freezing and thawing on F/T stability. Destabilization can be caused by either freezing or thawing. A slow freezing process is more detrimental to F/T stability than a fast freezing process; the latter actually preserves suspension stability during freezing.

Gordon Best Paper Competition.  相似文献

It is well established that a wide range of drugs of abuse acutely boost the signaling of the sympathetic nervous system and the hypothalamic–pituitary–adrenal (HPA) axis, where norepinephrine and epinephrine are major output molecules. This stimulatory effect is accompanied by such symptoms as elevated heart rate and blood pressure, more rapid breathing, increased body temperature and sweating, and pupillary dilation, as well as the intoxicating or euphoric subjective properties of the drug. While many drugs of abuse are thought to achieve their intoxicating effects by modulating the monoaminergic neurotransmitter systems (i.e., serotonin, norepinephrine, dopamine) by binding to these receptors or otherwise affecting their synaptic signaling, this paper puts forth the hypothesis that many of these drugs are actually acutely converted to catecholamines (dopamine, norepinephrine, epinephrine) in vivo, in addition to transformation to their known metabolites. In this manner, a range of stimulants, opioids, and psychedelics (as well as alcohol) may partially achieve their intoxicating properties, as well as side effects, due to this putative transformation to catecholamines. If this hypothesis is correct, it would alter our understanding of the basic biosynthetic pathways for generating these important signaling molecules, while also modifying our view of the neural substrates underlying substance abuse and dependence, including psychological stress-induced relapse. Importantly, there is a direct way to test the overarching hypothesis: administer (either centrally or peripherally) stable isotope versions of these drugs to model organisms such as rodents (or even to humans) and then use liquid chromatography-mass spectrometry to determine if the labeled drug is converted to labeled catecholamines in brain, blood plasma, or urine samples.  相似文献

In 2002–2004, we examined the flight responses of 49 species of native and exotic bark and ambrosia beetles (Coleoptera: Scolytidae and Platypodidae) to traps baited with ethanol and/or (−)-α-pinene in the southeastern US. Eight field trials were conducted in mature pine stands in Alabama, Florida, Georgia, North Carolina, and South Carolina. Funnel traps baited with ethanol lures (release rate, about 0.6 g/day at 25–28°C) were attractive to ten species of ambrosia beetles (Ambrosiodmus tachygraphus, Anisandrus sayi, Dryoxylon onoharaensum, Monarthrum mali, Xyleborinus saxesenii, Xyleborus affinis, Xyleborus ferrugineus, Xylosandrus compactus, Xylosandrus crassiusculus, and Xylosandrus germanus) and two species of bark beetles (Cryptocarenus heveae and Hypothenemus sp.). Traps baited with (−)-α-pinene lures (release rate, 2–6 g/day at 25–28°C) were attractive to five bark beetle species (Dendroctonus terebrans, Hylastes porculus, Hylastes salebrosus, Hylastes tenuis, and Ips grandicollis) and one platypodid ambrosia beetle species (Myoplatypus flavicornis). Ethanol enhanced responses of some species (Xyleborus pubescens, H. porculus, H. salebrosus, H. tenuis, and Pityophthorus cariniceps) to traps baited with (−)-α-pinene in some locations. (−)-α-Pinene interrupted the response of some ambrosia beetle species to traps baited with ethanol, but only the response of D. onoharaensum was interrupted consistently at most locations. Of 23 species of ambrosia beetles captured in our field trials, nine were exotic and accounted for 70–97% of total catches of ambrosia beetles. Our results provide support for the continued use of separate traps baited with ethanol alone and ethanol with (−)-α-pinene to detect and monitor common bark and ambrosia beetles from the southeastern region of the US.  相似文献

Glycidyl carbamate chemistry combines the excellent properties of polyurethanes with the crosslinking chemistry of epoxy resins. Glycidyl carbamate functional oligomers were synthesized by the reaction of polyfunctional isocyanate oligomers and glycidol. The oligomers were formulated into coatings with several amine functional crosslinkers at varying stoichiometric ratios and cured at different temperatures. Properties such as solvent resistance, hardness, and impact resistance were dependent on the composition and cure conditions. Most coatings had an excellent combination of properties. Studies were carried out to determine the kinetics of the curing reaction of the glycidyl carbamate functional oligomers with multifunctional and model amines. Detailed kinetic analysis of the curing reactions was also undertaken. The results indicated that the glycidyl carbamate functional group is more reactive than a glycidyl ether group.
