基于芡实叶脉的分叉结构及三角形的稳固特性设计了一分二-原、不分叉、一分二-全三角形和一分三4种穹顶温室。利用ANSYS有限元分析软件对4种温室进行了静力及线性屈曲分析,静力分析结果表明,4种温室在组合2(风载组合)作用下差别显著,即随着分叉级数增多,位移与强度分别降低了98. 92%和86. 46%,一分二-全三角形和一分三满足强度要求,且两者力学特性相近,耗材量相比不分叉结构分别增加了11. 88%和30. 18%;屈曲分析结果表明,竖直和水平荷载作用下,屈曲荷载分别是许用荷载的63. 52～26 737. 22倍与26. 86～11 300. 97倍(以单元长度为限),4种温室稳定性皆满足要求,且对竖直荷载响应显著,即分叉结构使屈曲荷载平均增加了334. 02%;综合得出一分二-全三角形为最优结构。基于第二相似理论,以1∶25制作的缩尺模型在12组应变试验中,与仿真结果无显著差异的组数占75%,25%略有偏差,试验相对误差为0. 18%～0. 69%,仿真过程准确可靠;模型横梁对组合1(雪载组合)响应明显,即各组应变均值在组合1作用是组合2作用下的5. 6倍,竖梁对组合2响应明显,即各组应变均值在组合2作用是组合1作用下的6. 2倍。

In addition to restoration of bladder, bowel, and motor functions, alleviating the accompanying debilitating pain is equally important for improving the quality of life of patients with spinal cord injury(SCI). Currently,however, the treatment of chronic pain after SCI remains a largely unmet need. Electrical spinal cord stimulation(SCS) has been used to manage a variety of chronic pain conditions that are refractory to pharmacotherapy. Yet, its efficacy, benefit profiles, and mechanisms of action in SCI pain remain elusive, due to limited research, methodological weaknesses in previous clinical studies, and a lack of mechanistic exploration of SCS for SCI pain control. We aim to review recent studies and outline the therapeutic potential of different SCS paradigms for traumatic SCI pain. We begin with an overview of its manifestations,classification, potential underlying etiology, and currentchallenges for its treatment. The clinical evidence for using SCS in SCI pain is then reviewed. Finally, future perspectives of pre-clinical research and clinical study of SCS for SCI pain treatment are discussed.

The paper uses data from 2002 to 2011 to make an analysis on trade reliance of China, the top 10 developed countries and top 10 developing countries in products of creative industries. A cross country comparison is done from global, country groups, and individual country perspective respectively. The findings include that the global trade in creative industry is growing steadily in terms of both absolute value and relative value. The trade reliance of major countries in creative products is getting deeper. The trade pattern in creative industry is taking shape. China＇s future markets in creative products include developed countries and high income developing economies. In view of this development trend, China＇s producers should make necessary adjustment in their production and market strategy so that they will not miss the future opportunities.

Chinese Chemical Letters 1998年第2期9卷 191-196页

作者： Jie LU guan Ying YANG Ling ZHAO Bu Xing HAN and Hai Ke YAN(Institute of Chemistry, Chinese Academy of Sciences, Beijing 100080) Institute of Chemistry Chinese Academy of Sciences Beijing 100080 China

The keto-enol tautomerization of ethyl acetoacetate (EAA) in supercritical CO2-ethanol mixture has been investigated at 308.15 K and at different pressures using UV-Visspectroscopy. A method for calculating the local composition about EAA has been developed based on the relationship between the equilibrium constant and dielectric property of the mixing solvent. The results indicate that the local concentration of ethanol surrounding EAA is much higher than that in the bulk.

Chicken body weight(BW) is a critical trait in breeding. Although genetic variants associated with BW have been investigated by genome-wide association studies(GWAS), the contributions of causal variants and their molecular mechanisms remain largely unclear in chickens. In this study, we construct a comprehensive genetic atlas of chicken BW by integrative analysis of 30 age points and 5 quantitative trait loci(QTL) across 27 tissues. We find that chicken growth is a cumulative non-linear process, which can be divided into three distinct stages. Our GWAS analysis reveals that BW-related genetic variations show ordered patterns in these three stages. Genetic variations in chromosome 1 may regulate the overall growth process, likely by modulating the hypothalamus-specific expression of SLC25A30 and retina-specific expression of NEK3. Moreover, genetic variations in chromosome 4 and chromosome 27 may play dominant roles in regulating BW during Stage 2(8-22 weeks) and Stage 3(23-72 weeks), respectively. In summary, our study presents a comprehensive genetic atlas regulating developmental stage-specific changes in chicken BW, thus providing important resources for genomic selection in breeding programs.
