职业紧张是指个体所在工作岗位要求与个人的能力、资源或需求不匹配时出现的生理和心理反应，现已 经成为全球范围内的流行病。长期以来，心血管疾病都是危及人类健康和生命的头号杀手，其致病因素虽然繁杂， 但职业紧张已被多项研究证明为心血管疾病的独立危险因子。研究发现，职业紧张水平与冠心病、心律失常、心力 衰竭等心血管疾病发病率有相关性，与高血压、动脉粥样硬化、糖尿病、吸烟等心血管疾病危险因素亦有关系；职业 紧张主要通过生物学机制、神经生物学-行为机制、阻碍药物治疗机制诱发心血管疾病，对人体健康产生严重危害。 [ABSTRACT FROM AUTHOR]

A prediction model of shale gas content was established based on the volumetric method. The total gas content of shale includes gas in the adsorbed phase and free phase. The amount of gas in the adsorbed phase was calculated with the consideration of mineral composition of shale, temperature, pressure, moisture and non-methane gas, and in the calculation of gas amount in the free phase the adsorbed phase volume was con-sidered. The model validation was conducted with the experimental data of in-situ desorption of JY-1 well in Fuling Jiaoshiba area. The results show that when the adsorbed phase volume is considered, the gas content calculated by the model is in good agreement with the field desorption data. Hwever, when the adsorbed phase volume is not considered, the gas content is overestimated by27%-38%. Moisture has little effect on the gas content of shale. Multicomponent gas not only changes the gas content of shale, but also changes the occurrence state of shale gas. The gas content will be overestimated by 5. 6%-31. 8%without the consideration of multicomponent gas. The accuracy of the model greatly depends on the results of indoor experiments. To obtain an accurate shale gas content, a further study of adsorption experiments of multicomponent gas on moisture-equilibrated shale should be carried out in the future study.
