| 1 | Effect of Mesoscale Land Use Change on Characteristics of Convective Boundary Layer:Semi-Idealized Large Eddy Simulations over Northwest China显示文摘Although large-scale topography and land use have been properly considered in weather and climate models, the effect of mesoscale and microscale heterogeneous land use on convective boundary layer(CBL) has not been fully understood yet. In this study, the influence of semi-idealized strip-like patches of oases and deserts, which resemble irrigated land use in Northwest China, on the CBL characteristics, is investigated based on the Weather Research and Forecasting(WRF)-large eddy simulation(LES) driven by observed land surface data. The influences of soil water content in oases on aloft CBL flow structure, stability, turbulent kinetic energy(TKE), and vertical fluxes are carefully examined through a group of sensitivity experiments. The results show that secondary circulation(SC)/turbulent organized structures(TOS) is the strongest/weakest when soil water content in oases is close to saturation(e.g.,when the oases are irrigated). With the decrease of soil water content in oases(i.e., after irrigation), SC(TOS) becomes weak(strong) in the lower and middle CBL, the flux induced by SC and TOS becomes small(large), which has a dramatic impact on point measurement of eddy covariance(EC) fluxes. The flux induced by SC and TOS has little influence on EC sensible heat flux, but great influence on EC latent heat flux. Under this circumstance, the area averaged heat flux cannot be represented by point measurement of flux by the EC method, especially just after irrigation in oases. Comparison of imbalance ratio(i.e., contribution of SC and TOS to the total flux) reveals that increased soil moisture in oases leads to a larger imbalance ratio as well as enhanced surface heterogeneity. Moreover,we found that the soil layer configuration at different depths has a negligible impact on the CBL flux properties. | Bangjun CAO Shuwen ZHANG Deqin LI Yanlin LI Linfan ZHOU Jiemin WANG | 2018 | Journal of Meteorological Research2018，32，3： | 4 |
| 2 | Radiation induced graft polymerization of multi-walled carbon nanotubes for superhydrophobic composite membrane preparation显示文摘Highly soluble multi-walled carbon nanotubes(MWNTs) were prepared by radiation-induced free radical graft polymerization of vinyl acetate(VAc) onto pristine MWNT surfaces. High resolution transmission electron microscopy(HR-TEM), Fourier transform infrared(FTIR) spectroscopy, and micro-Raman spectroscopy were used to confirm that poly(vinyl acetate)(PVAc) had been successfully grafted onto the surface of the MWNTs. The effects of experimental parameters on the degree of grafting(DG) of PVAc were also investigated, including adsorbed dose, dose rate, initial monomer concentration, and solvents. The grafted MWNTs(MWNTs-g-PVAc) exhibited good solubility in common organic solvents at high mass fraction. In addition, a superhydrophobic composite membrane could be readily fabricated by vacuum filtration of MWNTs-g-PVAc onto a supporting membrane, as was confirmed by water contact angle testing and visualization by scanning electron microscopy. | Bowu Zhang Siyuan Xie Rongmao Wei Hongjuan Ma Ming Yu Linfan Li Jingye Li | 2016 | Science China Chemistry2016，59，3： | 4 |
| 3 | High-selective removal of ultra-low level mercury ions from aqueous solution using oligothymonucleic acid functionalized polyethylene film显示文摘We prepare oligothymonucleic acid (OTA) functionalized polyethylene (PE) film and evaluate its selective removal ability of mercury ions at ultra-low levels in aqueous solution. The selective binding of OTA with mercury ions is confirmed by fluorescence in situ hybridization (FISH). The quantitative results via cold-vapor atomic fluorescence spectrometry (CVAFS) indicate that OTA-functionalized PE film is able to remove mercury ions at the sub-ppb level selectively from aqueous solution, even with the coexistence of other metal ions at concentrations 250-fold or higher than that of mercury. | YU Yang ZHANG BoWu YU Ming DENG Bo LI LinFan FAN ChunHai LI JingYe | 2012 | Science China Chemistry2012，55，10： | 3 |

| 10 | 4-5 Dielectronic Recombination of Li-like Argon Ions at the CSRm显示文摘The main cooler storage ring (CSRm) equipped with an electron-cooler creates an ideal platform for dielectronicrecombination (DR) experiments. In order to fully understand our DR experimental setup and especially the electronenergy detuning system, we have performed a DR calibration experiment using the Li-like argon ions at theCSRm.
