近年国产动画电影的长足发展令人瞩目。动画电影作为一种重要的电影样式和独特的电影工业形态，其生产制作非常符合电影工业美学的核心精神，如工业生产的系统性原则，工业效率的最大化目标，工业与美学的折中统一，大众文化主导性和多元文化融合的美学精神，电影人的“技术化生存”与技术美学视野。动画的媒介本性使其在传统文化影像转化方面有着再符号、再历史、抽象对象客观外化的优势，能够最大限度地满足“想象力消费”主体青少年观众的审美心理需求。动画天然的青年文化属性具有“合家欢”观看优势，能对传统文化等多个文化形态完成年轻化、喜剧化、流行性、反思性、解构性的重塑和融合。动画还表现出超前于真人电影的工业化生产思维、技术密集等工业特性，在数字技术不断消弭动画与电影媒介区隔的时代，动画的工业生产经验和技术美学前沿值得电影学习。

The electromigration behavior of eutectic SnAg solder reaction couples was studied at various temperature （25 and 120℃ when the current density was held constant at 104 A/cm^2 or 5×10^3 A/cm^2. Under the current density of 104 A/cm^2, scallop type Cu6Sn5 spalls and migrates towards the direction of electron flow at room ambient temperature （25℃）, but transforms to layer type Cu3Sn and leaves Kirkendall voids in it at high ambient temperature （120℃）. Under the current density of 5×10^3 A/cm^2 plus room ambient temperature, no obvious directional migration of metal atoms/ions is found. Instead, the thermal stress induced by mismatch of dissimilar materials causes the formation of superficial valley at both interfaces. However, when the ambient temperature increases to 120℃, the mobility of metal atoms/ions is enhanced, and then the grains rotate due to the anisotropic property of β-Sn.

1 Introduction In recent years, there has been increasing interest in the controlled synthesis of hollow nanoparticles because of their widespread potential applications. The hollow nanoparticles can be used as catalysts, adsorbents, drug-delivery carriers, chemical reactors, and so on^[1-6]. Some nano and micro spheres are em- ployed as hard or soft templates to produce hollow structures＆[7-10].

Blast furnace （BF） slag is a by-product of the ironmaking process and could be utilized to manufacture slag fiber by adding iron ore tailing. The crystallization behavior of the modified BF slag is significant to the fi- brosis process. To investigate the influence of basieity on the crystallization behavior, BF slag was modi- fied by adding iron ore tailing at room temperature and melted at 1 500 ℃. FactSage simulation, X-ray dif- fraction, scanning electron microscopy backscattered electron imaging coupled to an energy dispersive spectrometer, and hot thermocouple technique analysis were performed to explore the crystallization be- havior of the modified BF slag during the cooling process. It was found that the initial crystallization tem- perature increased with the increase in basicity. Melilite, anorthite, clinopyroxene, and wollastonite could be generated during the cooling process as basicity ranged from 0.7 to 0.9. Spinel could be found as one of the phases; however, wollastonite disappeared under a basicity of 1.0. The initial crystallization tempera- ture was controlled by the crystallization of melilite during the cooling process when the basicity of the modified BF slag ranged from 0. 7 to 1.0. Moreover, the cooling rate could also influence the crystalliza- tion of the modified BF slag.
