帮我翻译一下：因此，本文在已有研究的基础上确定调查维度，选取杭州市某小学教师作为调查对象，通过问卷调查法对其工作负担和幸福感现状进行调查，运用SPSS 26.0从性别、年龄、担任班主任情况、任教年级等方面对教师的工作负担和幸福感进行差异分析，再对教师的工作负担和幸福感各维度进行相关性分析，发现教师工作负担与幸福感存在极显著的负相关关系，且职称评比竞争激烈、工作时间安排欠妥、工作内容过于繁重、社会支持有所缺乏等因素会影响教师工作负担的加重与幸福感的降低。

Therefore, based on existing research, this article determines the survey dimensions and selects teachers from a primary school in Hangzhou City as the survey subjects. Through the questionnaire survey method, the current status of their work burden and happiness is investigated. Using SPSS 26.0, differences in work burden and happiness among teachers are analyzed from aspects such as gender, age, being a homeroom teacher, and teaching grade. Then, the correlation between the various dimensions of teachers' work burden and happiness is analyzed. The results show that there is a significant negative correlation between teachers' work burden and happiness. Factors such as intense competition in job title evaluation, inadequate work schedule, excessive workload, and lack of social support can increase teachers' work burden and reduce their happiness.
