全球能源互联网, 2021 工业蒸汽系统常配有透平发电系统以提高能源利用率，让工业用户能够灵活选择本地发电或外部电网供电。因响应电网需求而带来的发电调整可能会导致系统蒸汽供给和需求的不平衡，造成蒸汽系统运行的大范围波动，进而影响能源利用效率以及蒸汽系统运行安全。针对这一问题，讨论了含有蒸汽蓄热器的工业蒸汽系统结构，给出了相应的模型。进一步，提出了该系统发电灵活性的定义、关键性能指标以及基于最优运行模型的量化方法。通过位于欧洲的某造纸企业的实际工业蒸汽系统应用，评估了蒸汽蓄热器对于提高系统灵活性和关键性能指标的作用。

Latin American Policy, Volume 14, Issue 3, Page 388-407, September 2023., 2023 Abstract For years Colombia has been the world's largest coca producer. Its public management of crops for illicit use has swung between eradication, substitution, and, recently legalization. Forced eradication has been shown to be ineffective, and legalization is an incipient option, so the Peace Agreement puts forward substitution as the path to ...

The domestic struggle for traditional medical knowledge rights
Developing World Bioethics, Volume 23, Issue 1, Page 76-87, March 2023., 2023 Abstract In China, the local communities and various ethnic minorities still hold, sustain and develop traditional medicial knowledge (TMK), innovations, and practices within the original communities. TMK also has pharmaceutical option value, which has attracted interests in commercial use of TMK for pharmaceutical innovation in China.

Identifying treponemal disease in early East Asia
American Journal of Biological Anthropology, Volume 178, Issue 3, Page 530-543, July 2022., 2022 Syphilis in China before Vasco da Gama? Abstract Objectives Historic records suggest that a virulent form of treponematosis, sexually transmitted syphilis was introduced to Asia from Europe by the da Gama crew, who landed in India in 1498. Our objective is to assess the gross pathology of human skeletal remains from the Tang dynasty of China to test ...

Measurements of vapor pressures of alkanes by thermogravimetry(基于热重分析测定物质的蒸气压)
Zhejiang Daxue xuebao. Lixue ban, 2008 根据自由蒸发过程的Langmuir关系，将热重分析(TGA)用于正十六烷、正十七烷和正十八烷等3个正构烷烃的蒸气压测定，分别采用常数法和比较法计算蒸气压，其结果与文献数据符合较好.结果表明，只要选择合适的参考物质，TGA可以成功地应用于未知液体物质蒸气压的测定.同时，根据从TGA实验得到的蒸发速率和蒸气压数据，计算了蒸发过程的表观活化能和平均蒸发焓，发现活化能数值仅稍大于蒸发焓，证实TGA实验中的蒸发过程接近非活化自由蒸发过程.TGA是一种快速实用的蒸气压测量新方法，尤其适用于较低压力范围的蒸气压测定 ...
