Resumen En este trabajo, replicamos el enfoque de Salaberry (2011). En función a una tarea escrita de elección múltiple de 40 ítems basada en el discurso, analizamos la influencia que tienen la clase aspectual del verbo y la información de foco y fondo discursivos sobre el uso de la morfología verbal perfectiva e imperfectiva del español por aprendices sinohablantes de los niveles B1, B2, C1 (del MCER). Nuestros resultados muestran que la preferencia por usar asociaciones prototípicas predichas por la LAH y la DH coincide con los resultados de Salaberry (2011). Sin embargo, descubrimos que nuestros estudiantes de L1 chino mandarín muestran un patrón de desarrollo particular en comparación con los estudiantes de L1 inglés de Salaberry (2011).

Abstract In this work, we replicate the approach of Salaberry (2011). Based on an a written 40 item discourse based forced-choice task, we analyze the influence of lexical aspectual class and grounding information in discourse on the use of perfective and imperfective verbal morphology of Spanish by Chinese learners of three levels of proficiency (B1, B2, C1 of the CEFR). Our results show that the preference to use prototypical associations predicted by the LAH and the DH coincide with Salaberry’s (2011) results. However, we found that our L1 Mandarin Chinese learners show a particular developmental pattern compared with the L1 English learners in Salaberry (2011).

Abstract The fragmentation effect of PELE refers to the fragmentation of the jacket after PELE penetrates the metal target plate. Three sets of 30CrMnSiA tensile samples with different hardness were pulled to obtain the corresponding maximum principal tensile stress and fracture strain of the material. It was found that the greater the hardness, the smaller the fracture strain, and the more easily to shear failure; Then, PELE penetration metal thin target fragment recovery test was carried out. It was found that only HRC50 jacket had compression shear and other brittle material damage characteristics and produced ideal fragmentation effect during penetration; The results show that the greater the target velocity is, the greater the critical value of its own material breaking is. When its own breaking strain is less than the critical value, the jacket can play a fragmentation effect; For PELE penetrator with the same material performance that meet the crushing conditions, the greater the impact velocity, the more the number of jacket fragments and the larger the distribution radius of fragments. plate CrMnSiA failure Then out HRC HRC5 conditions
