    As one farmland site observed by the Chinese Flux Observation and Research Network (ChinaFLUX), this dataset collected field measurement of Changling alkali-saline paddy rice during 2018–2020 of Songnen Plain. It represents a typical and regional agricultural type in Northeast China.The dataset specifically includes half-hourly, daily, monthly and yearly scales of air temperature (Ta), air relative humidity (RH), water vapor pressure (e), saturated water vapor pressure (es), wind speed (Ws), wind direction (Wd), soil temperature (Ts), soil water content (SWC), rainfall (P), photosynthetically active radiation (PAR), net radiation (Rn) with four components, sensible heat flux (Hs), latent heat flux (LE), evapotranspiration (ET), net ecosystem CO2 exchange (NEE), ecosystem respiration (Re), gross ecosystem exchange (GEE), etc. The establishment and sharing of this dataset will provide the data support and theoretical basis for regional farmland ecosystem assessment and management.

    It is well known that the surface quality of laser gain crystal elements is very high in or- 9der to ensure the stability of laser system and laser output quality. In the ultra-precision machin- 10ing process of a new sesquioxide laser crystal Tm: GdScO3, it is required to achieve very high sur- 11face shape and very low surface defects. In this paper, the molecular dynamics simulation model 12of single particle grinding is established. It is found that the normal load and tangential friction 13imposed by abrasive particles on the surface of components cause the spalling of atoms on the 14substrate surface, which constitutes the removal of materials at the macro-level. At the same time, 15it causes the displacement of the sub surface atoms, which constitutes the microscopic defects in 16the structure. Through the structural characterization of macro defects, it is confirmed that the es- 17sence of micro defects is the amorphous and distortion of surface structure, and the depth can 18reach 100 nm. The results of lapping and polishing experiments show that the adjustment of 19pressure has limited effect on the improvement of surface defects in the process of machining 20crystal elements with granular abrasive. 2

    Terahertz (THz) radition has attracted significant attention toward applications on such as biology, imaging, sensing and communications due to its unique characteristics. Femtosecond laser filamentation is one of the important approaches to obtain THz pulse with ultra-broad bandwidth and high electric field. With the rapid development of femtosecond laser technology, plasma based THz generation by femtosecond laser has been well studied. Two theoretical models have reported for understanding the physical mechanism of THz pulse generation, namely the photocurrent model and the four wave mixing model, respectively. By applying an external static electric field to the laser-induced plasmas filament, the enhancement of THz radiation has been reported by several orders of magnitude. However, the physical mechanism of laser-induced THz emission under the external static electric field remains unclear because of the complex interaction of laser plasmas. In this paper, based on the photocurrent model, we analyze and numerically simulate the properties of THz emissiom from a DC-biased single-color femtosecond laser ionized gas micro-plasma. The results show that the photocurrent model is effective in interpreting the THz generation of DC-biased laser-induced gas plasmas.
