意大利是海外译介和传播莫言作品的重要国家,目前已译介出版10部莫言小说。莫言作品在意大利的译介整体呈现出较强的系统性、连续性、组织性及计划性,官方机构、大型出版社及知名汉学家群体是译介的主要推动者。莫言小说在意大利文学生产场域中的发展受到权力场规则辖制,其象征资本动态发展过程具有鲜明特点。莫言小说意语版的副文本信息反映出意大利文学场域对权力场域的迎合,封面设计大多采用符合西方对东方主义期待的摄影图片。而意大利权威评价体系对莫言的评论则体现出权力在文学场域中的渗透,行动者受场内位置结构与惯习影响,较热衷于讨论文学场外的政治因素。莫言在意大利的传播是文化场域中多方话语利益达成共识的进程,评论家、译者、出版社、评奖机构及莫言本人等多种资本占用者以复杂的方式彼此交叉互动,共同促成了莫言在意大利文学场域中象征资本的生产、流动、累积和增值。

作为教育行政部门、学校与教师权利和义务的重要平衡器,集体谈判在美国甚为流行。它顺应了教育民主化的潮流,对于维护教师权益和确保学校正常教育教学秩序起了重要作用。由于美国实行地方分权的教育管理体制,在集体谈判的内容、程序和方法等方面各州不尽相同,但都受制于美国联邦和各州的宪法与法律。

We investigated the photophysical property for the 1,1,2,3,4,5-hexaphenylsilole（HPS）through combined quantum mechanical and molecular mechanical（QM/MM）*** the displaced harmonic oscillator approximation with consideration of Duschinsky rotation effect（DRE）,the radiative and nonradiative rates of the excited-state decay processes for HPS are calculated by using the analytical vibration correlation function approach coupled with first-principles calculations for molecular *** intermolecular packing effect is incorporated through electrostatic interaction with force *** find that from gas phase to solid state（i）the side phenyl ring at the 5-position becomes coplanar with the central silacycle,which increases the degree of conjugation,thus accelerates the radiative decay process;（ii）the rotation of the side phenyl ring at the 2-position is restricted,which blocks the excited-state nonradiative decay *** synergetic effect largely enhances the luminescence quantum efficiency through reducing the nonradiative decay rate by about 4 orders of magnitude,leading to the radiative decay overwhelming the nonradiatvie decay in solid *** calculated solid-phase absorption and emission optical spectra of HPS are found to be in agreement with the experiment.

Financing Predicament of Small and Micro Enterprises in Hubei Province and its Solution

第十三届全国量子化学会议

Cyclometalated iridium（Ⅲ） complexes are widely used in the emissive layer of organic light-emitting diodes（OLEDs） due to their remarkable optical properties. Previous experiment investigations have shown that for the Ir（Ⅲ）complexes, the temperature-dependent decay behavior demonstrated a competing mechanism between metal-ligand charge transfer（MLCT） state and metal centered（MC） state. However, there have been only a few theoretical studies on quantitatively description on the rate constant for various decay pathways. In this work, we have constructed a computation model to systematically investigate the decay mechanism of Ir（ppz） 2（F ppy）. Both MLCT→S transition and MLCT→MC transformation are considered in this model with decay rate constants calculated at the first-principles level. Two distinct optimized geometries are found on T PES and then identified as MLCT or MC state based on spin density analysis. We found that the energy barrier of MLCT→MC transformation is low enough to overcome, and the rate constant of MLCT→MC transformation grows drastically as temperature increases, which indicates this pathway could be significant at high temperature. Strikingly, the calculated decay time vs. temperature shows a double-exponential form, which agrees with the experimental data. It is expected that the computation model in this work could be generalized to other Ir（Ⅲ） complexes, as they have similar temperature-dependent decay behaviors.

Controllable Synthesis of Externally Functional Dendronized Polymers

作者： Ziwei Yu Gui Jiang qian peng School of Grammar and Economics Wuhan University of Science and Technology

China’s economic development can create Chinese miracles, and the private economy has contributed. However, private enterprises, especially small and micro enterprises, are facing the "three big mountains" of market icebergs, financing high mountains and transition volcanoes. How to solve the financing dilemma of small and micro enterprises and promote the rapid and healthy development of small and micro enterprises is a key issue related to national economy and people’s livelihood.

We demonstrate laser ultrasonic generation in polyetheretherketone(PEEK). A middle infrared ZnGeP2 optical parametric oscillator(ZGP-OPO) pumped by a Q-switched Ho:YAG laser is employed as the ultrasonic excitation source. The ZGP-OPO has a spectral range of 3.2–3.4 μm. At an output wavelength of 3.4 μm, the maximum average output power of ZGP-OPO is 3.05 W with a pulse width of 24.3 ns, corresponding to a peak power of approximately 127.5 kW. The ultrasound is generated by the laser converted from 3.2 to 3.4 μm in the PEEK composite. The maximum ultrasonic signal amplitude in PEEK is 33 mV under the condition of thermoelastic excitation at 3.4 μm. Ablation occurs in the CPRF sample when the energy fluence is over 122.45 m J/cm^2. PEEK has a stronger absorption at 3.4 μm and laser-ultrasound generation is influenced by the wavelength of the laser.
