The adsorption of peroxymonosulfate（PMS） is crucial for PMS activation in the heterogeneous advanced oxidation processes. However, the investigation of PMS adsorption on the piezocatalysts still remains insufficient. In this work, bismuth oxychloride（BiO Cl） nanosheets were prepared as the piezocatalysts for PMS activation under ultrasonic vibration to remove carbamazepine（CBZ） in aqueous solutions. Up to92.5% of CBZ was degraded for 40 min in Bi OCl piezo-activated PMS system with the reaction rate constant of 0.0741 min-1, being 1.63 times that of the sum of BiOCl piezocatalysis, BiOCl-activated PMS, and vibration-activated PMS. PMS adsorption on the surface of BiOCl was specifically studied by comparing the microscopic structure change of the fresh and used Bi OCl. The results suggested that the piezoelectric field of Bi OCl was able to promote the tight adsorption of PMS on the surface, thus facilitating the fast activation of PMS through electrons transfer to produce reactive species(HO·, SO4·-, O2·-,1O2). This work presents an in-depth understanding for the role of piezoelectric effect on the adsorption and activation of PMS.

The Middle Proterozoic Chartai Group separated by two unconformities consists of three depositional se-quences: the Shujigou Formation-Zenglongchang Formation (DS Ⅰ), the Agulugou Formation (DS Ⅱ), andthe Liuhongwan Formation (DS Ⅲ). The carbonate platform and back-platform basin are the basic environ-ment model of the Chartai Group. The syndepositional faults on the oceanward side of the carbonate platformand large-scale slumping in the soft sediments are important marks of facies tracts. The newly establishedZenglongchan uplifting, an epeirogenetic uplifting, plays an important role in the formation of thepalaeogeographic framework of the Chartai Group. The stratigraphic correlation between the Chartai Groupand the Bayan Obo Group is made for the first time by using sequence stratigraphic principle and model estab-lished by P.R. Vail. The Chartai Group, which was deposited on the northern passive continental margin of theNorth China platfom, represents the platform cover.

背景:三维运动捕捉技术近年来通过其计算机辅助特性,针对不同病种建立了多样化模型。在青少年特发性脊柱侧弯方面还未有良好的模型具备对临床有指导意义的评估。目的:建立基于三维运动捕捉系统的青少年特发性脊柱侧弯胸廓容积与腹腔容积模型。方法:选取2020年7月至2021年7月于上海市养志康复医院(上海市阳光康复中心)、上海交通大学附属第六人民医院、上海交通大学附属儿童医学中心就诊的青少年特发性脊柱侧弯患者14例,年龄10-18岁,其中男性2例,女性12例。对所有纳入患者的胸围、Cobb’s角进行测量,并通过三维运动捕捉系统建立胸廓容积与腹腔容积模型,分析胸廓容积、腹腔容积与年龄、胸围、Cobb’s角的相关性。结果与结论:轻中度患者的最大吸气和最大呼气时胸廓容积以及腹腔容积与患者的胸围呈正相关,但与患者的Cobb’s角不相关。通过三维运动捕捉系统建立基于三维运动捕捉系统下青少年特发性脊柱侧弯胸廓容积与腹腔容积的模型,可以对Cobb’s角10°-45°患者的胸廓及腹腔进行无害、精准、量化的检测。
