A simple method was developed to relate soil sorptivity to hydraulic diffusivity and water absorption experiments were conducted utilizing one-dimensional horizontal soil columns to validate the relationship. In addition, an estimation method for hydraulic diffusivity with disc infiltrometer was developed. The results indicated a favorable fit of the theoretical relation to the experimental data. Also, the experiment with disc infiltrometer for estimating the diffusivity showed that the new method was feasible.

The objective of this 2-yr field trial, with a central composite rotatable design, was to assess and quantify the effects of separation of nitrogen fertilizer and water with alternating furrow irrigation （SNWAfI） practices on soil ammonia （NH3） emission during the summer maize （Zea mays L.） growing season. Ammonia volatilization after N sidedress and irrigation ranged from 4.8 to 17.0 kg N ha-1 and 6.2 to 20.6 kg N hal, respectively, in 2008 and 2009. The lower N input contributed to lower NH3 loss but lower yield, whereas the higher N input induced higher yield as well as higher NH3 loss. Ammonia intensity （NH3 volatilization per crop yield） after N sidedress and irrigation was 1.2-3.0 kg NH3-N t-1 yield in 2008 and 1.1-3.2 kg NH3-N t1 yield in 2009. The predicted minimum NH3 intensity in 2008 was 1.6 kg NH3-N fl yield and was obtained with the combined application of 127 kg N ha^-1 and 108 mm irrigation water. In 2009, the predicted minimum NH3 intensity was 1.3 kg NH3-N t-j yield and was obtained with the combined application of 101 kg N ha-1 and 83 mm irrigation water. We conclude that SNWAfI practices with optimum rates of water and fertilizer can significantly reduce soil NH3 intensity and maintain yield. It was more beneficial for sustainable farming strategies to minimize the NH3 intensity rather than reduce absolute NH3 emissions alone.

Abstract In this paper, we first prove that, for a non-zero function f∈D（Rn）, its multi-Hilbert transform Hnf is bounded and does not have compact support. In addition, a new distribution space D＇H（Rn） is constructed and the definition of the multi-Hilbert transform is extended to it. It is shown that D’H（Rn） is the biggest subspace of D＇（Rn） on which the extended multi-Hilbert transform is a homeomorphism.

High-precision measurements of the Nusselt number Nu for Rayleigh-B6nard （RB） convection have been made in rectangular cells of water （Prandtl number Pr ≈ 5 and 7） with aspect ratios （f~, fy） varying between （1, 0.3） and （20.8, 6.3）. for each cell the data cover a range of a little over a decade of Rayleigh number Ra and for all cells they jointly span the range 6x105 〈 Ra 〈1011. The two implicit equations of the grossmann-Lohse （gL） model together with the empirical finite conductivity cor- rection factorf（X） were fitted to obtain estimates of Nu∞ in the presence of perfectly conducting plates, and the obtained Nu∞ is independent of the cells＇ aspect ratios. A combination of two-power-law, Nu∞= O.025Ra0.357＋O.525Ra0.168, can be used to de- scribe Nu∞（Ra）. The fitted exponents 0.357 and 0.168 are respectively close to the predictions 1/3 and 1/5 of the 11μ. and 1Vμ re- gimes of the gL model. furthermore, a clear transition from the II. regime to the IVμ regime with increasing Ra is revealed.

The multi-color photometric light curves for contact binary AV Puppis(AV Pup) in VRcIc bandpasses are presented and analyzed by using the 2013 version of the Wilson-Devinney(W-D) *** solutions suggest that AV Pup is a peculiar A-subtype W UMa contact binary with a high mass ratio(q = m2/m1 = 0.896) and a low fill-out factor(f = 10%). Combining our newly determined times of minimum with those collected from literatures, the orbital period changes of this system are investigated. The O-C analysis indicates that the orbital period of AV Pup is increasing at a rate of d P/dt = 4.83 × 10-7 days yr-1, which can be explained by mass transfer from the less massive component to the more massive one.

目的:分析儿童优先愿景下我国儿童医疗保障水平及其不平等现状。方法:利用中国家庭追踪调查2020年数据,基于全民健康覆盖立方体框架,采用多元回归分析儿童与成人、儿童不同群体之间的医疗保障不平等现状。结果:我国儿童参保率为80.96%,住院和非住院群体医疗费用自付比例分别为64.71%和90.09%。参保率方面,儿童显著低于成人(OR=0.434,P<0.01);上学儿童显著高于未上学儿童(OR=2.075,P<0.01),留守儿童显著低于非留守儿童(OR=0.791,P<0.05)。医疗费用方面,儿童自付比例显著高于成人(β=0.066,P<0.01);6周岁及以上儿童自付医疗费用更低(β<-0.316,P<0.01),家庭收入较高(β<-0.022,P<0.05)、参保(β=-0.033,P<0.01)、住院(β=-0.270,P<0.01)儿童自付比例更低。结论:我国儿童医疗保障呈现双重不平等,即儿童保障水平显著低于成人,0~5周岁、未上学、留守以及低收入家庭儿童保障水平相对较低。建议通过优化儿童缴费标准和推行家庭联保等措施提高儿童参保率。同时,医保政策综合考虑儿童医疗卫生服务需求特点以提高保障水平。此外,重点关注和帮扶儿童医疗保障弱势群体,最终实现医疗保障领域的“儿童优先”。
