This paper examines the experiences of nine Chinese girls and young women as they explore and negotiate queer subjectivities within the constraints of patriarchal and (hetero)sexual norms surrounding girlhood and young femininity. I focus on filial piety ( xiaoshun) as a normative gendered discourse being reconfigured in changing gender, familial and other power dynamics in China. I argue that the discourse of filial piety continues to naturalise a heteronormative girlhood that will smoothly transition into young womanhood prepared to take on responsibilities of ‘getting married and having kids’. This narrative, however, is in tensions with girls and young women’s diversified expressions of sexualities. Through the participants’ own accounts of queer explorations, I demonstrate how they actively engage and reflect on these tensions with familial and filial discourses while navigating the (im)possibilities of becoming queer girls across varied socioeconomic and family backgrounds. The findings of this study offered new insights into how familism and filial piety are woven into Chinese gender and sexual politics and being constantly (re)negotiated. My conceptualisation of queer girlhoods in China shows how queer girls and young women are marginalised in and around family. In the meantime, it demonstrates the emergent strategies of queer resistance and negotiations of filial piety through delaying marriage and managing familial intimacy.

To solve the problems with the penetrant testing of transportable pressure vessels (“TPVs”), such as failure to detect near-surface defects, low testing efficiency, and damage of penetrating agents to testers’ health and the high-purity media in the TPVs, an experimental study on the eddy current array (“ECA”) testing technology is carried out, and the result is compared with the results of the dye penetrant testing and fluorescent penetrant testing. According to the experiment result, the ECA testing technology is characterized by moderate requirements for the status of the surface to be tested, fast testing, environmental-friendliness, electronic data storage, testing imaging, and accurate testing results. These advantages enable the ECA testing technology to be a green and environmental-friendly nondestructive testing technology that will promote future development and have exciting prospects in TPV testing.
