PLATCOL, Plataforma Multilingüe de Diccionarios de Colocaciones: el caso del chino

El objetivo de esta contribución es realizar algunas observaciones sobre el procesamiento de las colocaciones extraídas de la lengua china, así como discutir los problemas que hemos observado al trabajar con esta lengua en la Plataforma Multilingüe de Diccionarios de Colocaciones (PLATCOL). PLATCOL incluirá colocaciones en inglés, portugués, español, francés y chino (Orenha-Ottaiano et al. 2021) y forma parte del proyecto A phraseographical methodology and model for an Online Corpus-Based Multilingual Collocations Dictionary Platform (Proceso FAPESP 2020/01783-2). En la plataforma se ha seguido una metodología unificada para obtener los datos que poblarán las entradas. Esta metodología que funciona con razonable eficacia en las demás lenguas –aunque requiere una fase supervisada de corrección y validación– conlleva un esfuerzo suplementario en el caso de la lengua china donde, por ejemplo, discrepancias en la asignación de categorías gramaticales pueden afectar a la eficacia del método a la hora de extraer candidatos

Perspectives on the Global Economic Order in 2021: A U.S.-China Essay Collection

This volume consists of a series of parallel essays on the global economic order by U.S. and Chinese scholars who have participated in our dialogue. It complements similar volumes published in 2017 and 2019. The value of this text is found not only in the ideas presented by the essayists but also in the opportunity to "listen" to each other as we manage our differences and seek a shared reform agenda for the global economic order.These essays were drafted during the Summer of 2021 and reflect data that may have changed since that period

Research on Flexural Bearing Capacity of Reinforced Hollow Slab Beams Based on Polyurethane Composite Material Positive and Negative Pouring Method

In order to explore the construction technology of prestressed steel strand–polyurethane cement composites for strengthening hollow slab beams, two reinforced test beams (L1, L2) and one unreinforced test beam (L0) were subjected to flexural static load tests. The deflection, ductility, stiffness, strain, and bearing capacity of each test beam were used to summarize the influence of different reinforcement techniques on the flexural performance of hollow slab beams. Research shows the prestressed steel strand–polyurethane composite material was well-bonded to the hollow slab beam, which effectively inhibits the development of concrete cracks and delays the damage process of hollow slab beams, that the reinforcement effect of the test beam L1 under the reverse pouring process was remarkable, and the bending performance of the test beam L2 under the forward pouring process of the simulated real bridge was good, which was much better than that of the unreinforced beam L0. The use of tensile prestressed steel strands and forward casting of polyurethane–cement composite materials effectively improved the flexural bearing capacity of the test beams, and this reinforcement process can be further extended to engineering applications

Experimental Study on the Bending Resistance of Hollow Slab Beams Strengthened with Prestressed Steel Strand Polyurethane Cement Composite

In order to explore the toughening performance and failure mechanism of hollow slab beams strengthened with prestressed steel strand polyurethane cement composite, three test beams (L1–L3) were strengthened and one test beam (L0) was used as a comparison. The influence of different tensile stresses of steel strand and fiber additions on the flexural bearing capacity of the hollow slab beams, was studied. The cracking characteristics, load deflection relationship, ductility and strain of each test beam were compared and analyzed. The test results showed that the toughened material was well bonded to the hollow slab beam and the steel strand, which effectively inhibited the development of cracks in the test beams. The flexural bearing capacity of the strengthened test beams was significantly improved. The use of prestressed steel strand polyurethane cement composite material effectively improved the flexural bearing capacity of the test beams, and this reinforcement process can be further extended to engineering applications
