| 1 | Explicit analytical solutions of non-Fourier heat conduction equation for IC chip显示文摘Four basic explicit analytical solutions of non_Fourier heat conduction equation simulating IC chip thermal condition are derived. Some other analytical series solutions can also be derived with the above_mentioned basic solutions. Analytical solution has its own irreplaceable important meaning in theory. In addition, as the standard solution to check the accuracy, convergence and effectiveness of various numerical computational methods and their differencing schemes, grid generation ways and so on, the analytical solution is very useful also for the newly rapidly developing computational heat transfer. | Ruixian Cai Na Zhang | 1998 | Chinese Science Bulletin1998，43，13： | 11 |
| 2 | A new method for deriving analytical solutions of partial differential equations-Algebraically explicit analytical solutions of two-buoyancy natural convection in porous media显示文摘Analytical solutions of governing equations of various phenomena have their irre-placeable theoretical meanings. In addition, they can also be the benchmark solu-tions to verify the outcomes and codes of numerical solutions, and even to develop various numerical methods such as their differencing schemes and grid generation skills as well. A hybrid method of separating variables for simultaneous partial differential equation sets is presented. It is proposed that different methods of separating variables for different independent variables in the simultaneous equa-tion set may be used to improve the solution derivation procedure, for example, using the ordinary separating method for some variables and using extraordinary methods of separating variables, such as the separating variables with addition promoted by the first author, for some other variables. In order to prove the ability of the above-mentioned hybrid method, a lot of analytical exact solutions of two-buoyancy convection in porous media are successfully derived with such a method. The physical features of these solutions are given. | CAI RuiXian LIU QiBin | 2008 | Science China(Physics,Mechanics & Astronomy)2008，51，11： | 6 |
| 3 | A near-infrared fluorescent probe for fluorine ions and its application in the imaging of HepG2 cells显示文摘In this study, we have designed and synthesized a new near-infrared (NIR) fluorescent probe (BODIPY-Se) to detect fluorine ions (F-) using a B-Se bond to connect the fluorescent dye BODIPY and benzotrifluoride. The probe exhibited a highly selective fluorescence response to F- with a detection limit of 7.4×108 mol/L. The excitation and emission spectra of the probe in the NIR region avoid background fluorescence interference present in biological systems. The fluorescent imaging of HepG2 cells demonstrated that the newly developed probe should be broadly applicable to detect F- in living cells. | GONG Wei SU RuiXian LI Lu XU KeHua TANG Bo | 2011 | Chinese Science Bulletin2011，56，31： | 4 |
| 4 | Transverse mode instability mitigation in a high-power confined-doped fiber amplifier with good beam quality through seed laser control显示文摘In this work,a confined-doped fiber with the core/inner-cladding diameter of 40/250μm and a relative doping ratio of 0.75 is fabricated through a modified chemical vapor deposition method combined with the chelate gas deposition technique,and subsequently applied in a tandem-pumped fiber amplifier for high-power operation and transverse mode instability(TMI)mitigation.Notably,the impacts of the seed laser power and mode purity are preliminarily investigated through comparative experiments.It is found that the TMI threshold could be significantly affected by the seed laser mode purity.The possible mechanism behind this phenomenon is proposed and revealed through comprehensive comparative experiments and theoretical analysis.Finally,a maximum output power of 7.49 kW is obtained with the beam quality factor of approximately 1.83,which is the highest output power ever reported in a forward tandem-pumped confined-doped fiber amplifier.This work could provide a good reference and practical solution to improve the TMI threshold and realize high-power high-brightness fiber lasers. | Hanshuo Wu Haobo Li Yi An Ruixian Li Xiao Chen Hu Xiao Liangjin Huang Huan Yang Zhiping Yan Jinyong Leng Zhiyong Pan Pu Zhou | 2022 | High Power Laser Science and Engineering2022，10，6： | 3 |
| 5 | Influencing factors of inpatient expenditure pattern for cancer in China, 2015显示文摘Objective: We analyzed the proportion of cancer-caused hospitalization expenses in total hospitalization expenses from national authoritative data and explored influencing factors of the proportion so as to provide effective data information for more rational utilization of health resources.Methods: Two-level lineal regression model was used to explore influencing factors of ratios of the cancer inpatient expenditure over the total inpatient expenditure of hospitals in China in 2015. A total of 40.76 million inpatient medical records were used to generate the outcome variables, while the explanatory variables were from hospital information database and China Health and Family Planning Statistical Yearbook and literatures.Results: Inpatient expenditure pattern for cancer(IEPC) varied largely across provinces, ranging from 3.03% to19.61%. The major sources of variability were from the differences of hospital level and number of beds. There was homogeneity within a province, while heterogeneity between the provinces. Rising one level of the hospital led to the increase of 0.475 natural logarithm units of IEPC averagely. The number of beds increasing 1,000 each made the natural logarithm of IEPC increase one unit averagely.Conclusions: Our study showed that a considerable proportion of IEPC variation could be explained by the differences of hospital level and number of beds. It implied that it is possible to estimate disease-specific ratio of inpatient expense taking into account key influencing factors in China. Furthermore, this study is an input to economic and financial analyses and provides evidence for future study on the national economic burden of cancer. | Lan Lan Yue Cai Tao Zhang Ruixian Wu Ming Xue Qun Meng | 2017 | Chinese Journal of Cancer Research2017，29，1： | 3 |
| 6 | The calmodulin-dependent protein kinase II inhibitor KN-93 protects rat cerebral cortical neurons from N-methyl-D-aspartic acid-induced injury显示文摘In this study, primary cultured cerebral cortical neurons of Sprague-Dawley neonatal rats were treated with 0.25, 0.5, and 1.0 μM calmodulin-dependent protein kinase II inhibitor KN-93 after 50 μM N-methyl-D-aspartic acid-induced injury. Results showed that, compared with N-methyl-D-aspartic acid-induced injury neurons, the activity of cells markedly increased, apoptosis was significantly reduced, leakage of lactate dehydrogenase decreased, and intracellular Ca(2+) concentrations in neurons reduced after KN-93 treatment. The expression of caspase-3, phosphorylated calmodulin-dependent protein kinase II and total calmodulin-dependent protein kinase II protein decreased after KN-93 treatment. And the effect was apparent at a dose of 1.0 μM KN-93. Experimental findings suggest that KN-93 can induce a dose-dependent neuroprotective effect, and that the underlying mechanism may be related to the down-regulation of caspase-3 and calmodulin-dependent protein kinase II expression. | Xuewen Liu Cui Ma Ruixian Xing Weiwei Zhang Buxian Tian Xidong Li Qiushi Li Yanhui Zhang | 2013 | Neural Regeneration Research2013，8，2： | 3 |

| 8 | The effects of straw‑returning and inorganic K fertilizer on the carbon–nitrogen balance and reproductive growth of cotton显示文摘Background:Many studies have indicated that straw-returning could meet part or even all of the potassium(K)demand for crop growth in the field,but few have compared the effects of crop straw as K source and inorganic K fertilizer on carbon–nitrogen(C–N)balance of cotton and the reproductive growth.To address this,field experiments were conducted using the cotton cultivar,Siza 3,under there treatments(CK as control group one,no crop straw and inorganic K fertilizer were applied;K150 as control group two,150 kg·ha^(-1) of K2O was applied;and W9000,9000 kg·ha^(-1) wheat straw,which could provide K2O about 150 kg·ha^(-1),was incorporated into soil).Results:Although the final reproductive organ biomass did not differ between W9000 and K150,W9000 had a higher ratio of reproductive organ biomass to total biomass(RRT),suggesting that straw-returning was more conducive to the allocation of biomass to reproductive organs.The theoretical maximum biomass of reproductive organ was higher,but the average and maximum accumulation rates of reproductive organ biomass were 2.8%∼8.3%and 2.5%∼8.2%lower under W9000 than K150.Also,the duration of rapid-accumulation period for reproductive organ biomass(T)was 2.0∼2.8 d longer under W9000 than K150,which was a reason for the higher RRT under W9000.Straw-returning altered the dynamics of leaf K with the growth period,so that W9000 had a more drastic effect on leaf C metabolism than K150.Consequently,lower soluble sugar/free amino acid and C/N ratios were measured under W9000 than K150 at boll-setting(BSS)and boll-opening(BOS)stages.Higher leaf net photosynthetic rate,sucrose phosphate synthase and sucrose synthase activities,and lower acid invertase activity were observed under W9000 than K150 at BSS and BOS and these were more conducive to sucrose accumulation.However,less sucrose was measured under W9000 than K150 at these stages.This should be because straw-returning promoted the assimilate transport capacity when compared with inorganic K fertilizer application,which also explained the higher RRT under W9000 than K150.The lower acid invertase activity under W9000 inhibited the conversion of sucrose to other sugars,hence lower contents of soluble sugar and starch were measured under W9000 than K150.Conclusion:Under low K condition,crop straw as K source can increase the assimilate transport from source to sink,leading to lower C/N ratio in leaf and higher allocation of biomass to reproductive organs than inorganic K fertilizer. | HU Wei YU Chaoran ZHAO Wenqing LIU Ruixian YANG Changqinand ZHOU Zhiguo | 2021 | Journal of Cotton Research2021，4，4： | 2 |
| 9 | Algebraically explicit analytical solutions of two-buoyancy natural convection in porous media显示文摘Analytical solutions of governing equations of various physical phenomena have their own irreplaceable theoretical meaning. In addition, they can also be the benchmark solutions to verify the outcomes and codes of numerical solution, and to develop various numerical methods such as their differencing schemes and grid generation skills as well. In order to promote the development of the discipline of natural convection, three simple algebraically explicit analytical solution sets are derived for a non-linear simultaneous partial differential equation set with five dependent unknown variables, which represents the natural convection in porous media with both temperature and concentration gradients. An extraordinary method separating variables with addition is applied in this paper to deduce solutions. | CAI Ruixian*, ZHANG Na and LIU Weiwei (Institute of Engineering Thermophysics, Chinese Academy of Sciences, Beijing 100080, China) | 2003 | Progress in Natural Science:Materials International2003，13，11： | 2 |
