| 1 | A comparison of summer precipitation structures over the South China Sea and the East China Sea based on tropical rainfall measurement mission显示文摘The three-dimensional structures of summer precipitation over the South China Sea(SCS)and the East China Sea(ECS)are investigated based on tropical rainfall measurement mission(TRMM).The primary results are as follows.First,both the convective and stratiform precipitation rates in the SCS are much higher than those of the ECS.The contribution of the convective cloud precipitation to the surface precipitation is primarily over the SCS and the ECS with a proportion of about 70%,but the contribution of convective cloud precipitation is slightly larger in the SCS than the ECS.The contribution of stratus precipitation is slightly larger in the ECS than that in the SCS.Second,the content of cloud particles and precipitation particles in the ECS in June was greater than that in the SCS,while in July and August,the content of cloud and precipitation particles in the ECS was less than that in the SCS.Third,the latent heat profile of the ECS is quite different from that of the SCS.In June,the peak values of evaporation and condensation latent heating rates in the ECS are greater than those in the SCS.In July and August,however,the peak values of evaporation and condensation latent heating rates in the ECS are about 0.05/h less than those in the SCS. | LI Jiangnan YANG Chaofeng LI Fangzhou HE Qihua LI Weibiao | 2013 | Acta Oceanologica Sinica2013，32，11： | 3 |
| 2 | The associations of lens power with age,axial length and type 2 diabetes mellitus in Chinese adults aged 50 and above显示文摘Background:To investigate the associations of lens power with age,axial length(AL),and Type 2 diabetes mellitus(DM)in Chinese adults aged 50 and above.Methods:Random clustering sampling was used to identify adults aged 50 years and above in urban regions of Shanghai.The participants underwent a comprehensive ophthalmic examination including subjective refraction,autorefraction,and IOL-Master.The crystalline lens power was calculated using Bennett’s formula.Results:A total of 4177 adults were included.A linear decrease in lens power was observed both with age and with AL,followed by a stop of lens power loss after the age of 70 or when AL≥25 mm,respectively.Participants with Type 2 DM presented higher lens power(0.43 diopter(D),p<0.001)and thicker lens thickness(0.06 mm,p<0.001).In multivariate regression models,there was a positive correlation between lens power and Type 2 DM when age<75 years(p<0.001)or AL<25 mm(p<0.001)after adjusting for other factors,while no significant association was found in participants aged≥75 years(p=0.122)or with AL≥25 mm(p=0.172).Conclusions:The lens power in adults aged 50 and above exhibited two stages with age and with AL.Type 2 DM caused an increase in lens power,which was not seen in participants aged≥75 years or with AL≥25 mm. | Luyao Ye Jiangnan He Xinji Zhang Yi Xu Qiuying Chen Yao Yin Ying Fan Lina Lu Jianfeng Zhu Haidong Zou Xun Xu | 2020 | Eye and Vision2020，7，1： | 0 |
| 3 | Lithiation-induced controllable vacancy engineering for developing highly active Ni_(3)Se_(2) as a high-rate and large-capacity battery-type cathode in hybrid supercapacitors显示文摘The poor rate capability and low capacity are huge barriers to realize the commercial applications of battery-type transition metal compounds(TMCs) cathode.Herein,numerous Se vacancy defects are introduced into the Ni_(3)Se_(2)lamellas by pre-lithiation technique,which can be acted as a novel class of battery-type cathode for hybrid supercapacitors.Appropriately modulating the contents of the preembedded lithium(Li) ions can induce a controllable vacancy content in the series of as-prepared products,effectively endowing a fast reaction kinetic and high activity for the cathode.Benefiting from the distinct design,the optimized cathode(Li2-Ni_(3)Se_(2)) presents a high specific capacity of 236 mA h g^(-1)at1 A g^(-1),importantly,it can still possess 117 mA h g^(-1)when the current density is increased up to 100A g^(-1),exhibiting relatively high rate capability.It is much superior to other battery-type TMC cathodes reported in previous studies.Moreover,the cathode also shows the excellent cycling stability with 92%capacity retention after 3,000 cycles.In addition,a hybrid supercapacitor(HSC) is assembled with the obtained Li2-Ni_(3)Se_(2)as the cathode and active carbon(AC) as the anode,which delivers a high energy density of 77 W h kg^(-1)at 4 kW kg^(-1)and long-term durability(90% capacitance retention after 10,000 cycles).Therefore,the strategy not only provides an effective way to realize the controllable vacancy content in TMCs for achieving high-perfo rmance cathodes for HSC,but also further promotes their large-scale applications in the energy storage fields. | Yinna He Ting Liu Jiangnan Song Yiwei Wang Yuxiao Zhang Jie Feng Alan Meng Guicun Li Lei Wang Jian Zhao Zhenjiang Li | 2023 | Journal of Energy Chemistry2023，，3： | 0 |
| 4 | Loading rate and holding load dependent room temperature nanoindentation creep behavior of 60NiTi alloy:Individual and coupling effects显示文摘60NiTi alloy is highly promising for aerospace bearings and mechanisms.Shock load that is inevitably generated during launching process brings about an quick loading process and transient load duration,and may further results in an unnoticed but detrimental creep deformation.On this account,the nanoindentation creep behavior of solution-treated 60NiTi alloy at room temperature and the corresponding influencing mechanism were studied.The results show that creep displacement was dominated by strain rate at the very beginning of holding stage.Strain rate and flow stress at the very beginning of holding stage were increased with an increased loading rate but declined with increasing holding load or with simultaneously increasing loading rate and holding load.The underlying mechanisms were provided as nucleation and absorption of geometrically necessary dislocations(GNDs)associated with strain gradient plasticity theory rather than the model based on the consumption of creep deformation at loading stage. | Wanjun He Qunfeng Zeng Chao Yan Jianing Zhu Danli Zhang Jiangnan Cao | 2022 | Journal of Materials Science & Technology2022，，6： | 0 |
