Cultural Melting Bath: Meet the Artist

This pamphlet from 1997 details the hours and location of the Queens Museum of Art as well as an upcoming event for the Contemporary Currents exhibition. The event, “Meet the Artist,” was a program in conjunction with Cai Guo-qiang’s exhibition, Cultural Melting Bath: Projects for the 20th Century. The program included a panel discussion with the artist, Cai Guo-qiang, and various other directors and consultants associated with the museum, followed by a reception and bathing demonstration.

Functional groups of benthic macrofauna in the 14th Yong intertidal zone of Nansha,Guangzhou

大型底栖动物根据食性可分为浮游生物食者(planktophagous,Pl)、植食者(phytophagous,Ph)、肉食者(carnivorous,C)、杂食者(omnivorous,O)和碎屑食者(detritivorous,D)五个功能群。本文根据2007–2008年度和2013–2014年度在茳芏(Cyperus malaccensis)、海桑(Sonneratia caseolaris)2种生境调查获得的各4个季度的大型底栖动物数据,分析了广州南沙十四涌潮间带大型底栖动物功能群的生境差异、季节变化和年际变化。2007–2008年度采集到26种大型底栖动物,低于2013–2014年度的36种。无论是2007–2008年度还是2013–2014年度,茳芏、海桑生境的大型底栖动物均以植食者的栖息密度和生物量最高,碎屑食者的栖息密度和生物量最低。生境比较得出,茳芏生境大型底栖动物浮游生物食者(Pl)的丰富度指数(d)、均匀度指数(J)和多样性指数(H')均高于海桑生境。年度比较得出,在茳芏和海桑生境,2013–2014年度浮游生物食者的丰富度指数、均匀度指数和多样性指数均高于2007–2008年度,这是因为2013–2014年度采集到红树蚬(Gelonia coaxans)和彩虹明樱蛤(Morerlla iridescens)等,而2007–2008年度没有采集到。Benthic macrofauna were classified into 5 functional groups,i.e.planktophagous(Pl),phytophagous(Ph),carnivorous(C),omnivorous(O) and detritivorous(D).The biotope difference,seasonal and annual variations of functional group of benthic macrofauna in the intertidal zone of the 14 th Yong of Nansha,Guangzhou were analyzed in this study according to the four seasonal data of benthic macrofauna collected in two biotopes(Cyperus malaccensis and Sonneratia caseolaris) in 2007–2008 and 2013–2014.A total of 26 species were recorded in 2007–2008,which was lower than 36 species in 2013–2014.Both in 2007–2008 and 2013–2014,phytophagous group showed the highest value while detritivorous group shared the lowest one in density and biomass.Habitat comparison showed that the abundance index(d),evenness index(J) and diversity index(H') of planktophagous group in Cyperus malaccensis habitat were all higher than those in Sonneratia caseolaris habitat.Annual comparison showed that the abundance index,evenness index and diversity index of planktophagous group in 2013–2014 were all higher than those in 2007 –2008 both in Cyperus malaccensis and Sonneratia caseolaris habitats because the planktophagous such as Gelonia coaxans and Morerlla iridescens and so on were collected in 2013–2014 but they were not found in 2007–2008.国家自然科学基金(41176089和41376113

Selective Catalytic Hydrogenation of Cinnamaldehyde to Hydrocinnamaldehyde

采用煤质活性炭作载体,分别用HNO3、H2O2和(NH4)2S2O8进行预处理,然后用浸渍法负载PdCl2,在H2流中还原得到Pd/C催化剂,用于肉桂醛(CAL)选择加氢制氢化肉桂醛(HCAL)的反应。考查了Pd负载量,反应温度和压力对加氢反应的影响,优化了反应条件。进一步考查了助剂Fe、Co、Ni[1]对反应的影响。最终,CAL转化率为98%,HCAL选择性为88%。Coal-based activated carbon was pretreated with HNO_3,H_2O_2 and(NH_4)_2S_2O_8 before selected as support.A series of Pd/C catalysts were prepared by means of impregnation and with PdCl_2 as precursor.It was reduced in H_2 stream,and applied to selective hydrogenation of cinnamaldehyde to hydrocinnamaldehyde.Effects of Pd-loading,reaction temperature and pressure were discussed.In addition,promoters of Fe,Co,Ni were introduced to the catalysts.At last proper conditions for the reaction were found,and 88% selectivity to HCAL at 98% conversion of CAL was obtained.国家自然科学基金(No.20203014

光学微球腔谐振模式间隔参数的一种简便计算方法

从光学微球腔谐振模式的本征方程出发,提出了一种利用求导法计算谐振模式间尺寸参数(x)间隔的有效方法。在Lam求得的尺寸参数计算公式基础上,依据谐振模式角量子数(l)必须为整数且远远大于1的性质,相邻模式(Δl=1)间的尺寸参数间隔可近似表示为相应尺寸参数的导数,从而可利用求导法计算谐振模式之间的尺寸参数间隔。研究表明,径向量子数i=1的谐振模式的尺寸参数间隔与Mie散射理论求得的精确数值解之间的相对误差在0.05%以内,并且与实验测量数据基本一致。求导法因不需要进行繁琐的级数展开,从而大大简化了计算程序,为光学微球腔的实验研究提供了理论指导

Community of benthic macrofauna on sandy intertidal zone in Chinese Horseshoe Crab Reserve in Pingtan island,China

2015年7月底,在平潭岛中国鲎(Tachypleus; tridentatus)保护区沙质潮间带进行了大型底栖动物调查。结果表明,在山岐澳和坛南湾沙质潮间带未发现鲎的幼体和成体,证实中国鲎在山岐澳和坛; 南湾已经面临濒危的境况。山岐澳潮间带的大型底栖动物物种数、物种多样性指数(H')、均匀度指数(J)和丰度指数(d)均高于坛南湾潮间带的大型底栖动; 物物种数、物种多样性指数、均匀度指数和丰度指数,而山岐澳潮间带的大型底栖动物栖息密度和生物量低于坛南湾潮间带的大型底栖动物栖息密度和生物量。两个; 海湾大型底栖动物群落的差异与肋(虫昌)螺(Umbonium; costatum)分布有关,坛南湾潮间带栖息着高密度的肋虫昌螺,而在山岐澳潮间带肋(虫昌)螺很少。AZTI's海洋生物指数(AMBI)和多变量海; 洋底栖生物指数(M-AMBI)值证实山歧澳和坛南湾沙质潮间带生态环境均属于受轻度扰动状态。山岐澳主要受海水养殖的影响,吊养的生物和浮筒减缓了水动; 力,导致山岐澳潮间带低洼区表层为泥质沉积物。坛南湾是旅游区,潮间带受人为踩踏较多。At the end of July 2015 , the benthic macrofauna were investigated in; sandy intertidal zone in Chinese Horseshoe Crab Reserve in Pingtan; island. The results showed that both the larvae and adult of Chinese; horseshoe crab were not found in sandy intertidal zone in Shanqi bay and; Tannan bay. It was confirmed that Tachypleus tridentatus stayed in an; endangered situation in the two bays. The species number, species; diversity index (H'),evenness index (J) and a-bundance index (d) of; benthic macrofauna in Shanqi bay were all higher than those in Tannan; bay,while the density and biomass of benthic macrofauna in the; intertidal zone of Shanqi bay were lower than those in Tannan bay. The; difference of benthic macrofaunal community between Shanqi bay and; Tannan bay was related to the distribution of Umbonium costatum . The; density of Umbonium costatum was high in Tannan bay,but it was few in; Shanqi bay. The values of AZTI' s Marine Biotic Index ( AMBI) and; Multivariate Marine Benthic Index (M-AMBI) showed that the ecological; and environmental status both in Shanqi bay and Tannan bay were slightly; disturbed. The mariculture was the key factor in Shanqi bay,because the; suspending aquatic organisms and floats retarded hydrodynamic force led; to muddy sediment in lower intertidal zone in Shanqi bay. Tannan bay is; a tourism region, where has more artificial tread than Shanqi bay.海洋公益项目; 国家自然科学基金面上项目; 厦门大学2015年大创资助项
