浑水渗流在水利工程的反滤设计、浑水浇灌、堤坝渗流控制等方面都有较大影响,目前理论多采用稳定渗流计算方法,忽略了渗流过程中粗细颗粒与水力的耦合作用。自制渗流装置,将不同控制粒径浑水、不均匀系数粗粒土柱和水头等作为基本控制因素,研究不同工况下浑水中悬浮颗粒对粗粒土土柱中的渗透特性影响;推导了变渗透系数浑水渗流计算微分方程,通过对比验证和公式修正,结果表明:粗粒土中颗粒淤积率与控制粒径C_(0.075)含量符合Boltzmann函数关系;C_(0.075)是重要的影响因子,浑水颗粒在粗粒土柱的运移、沉积和淤堵形态过程大致可分为4种形态:表层堆积淤堵形态(S型);表层-内部双重淤堵形态(S-I型);内部孔隙淤堵形态(I型);暂态孔隙淤堵形态(P型)。土柱C_(u)越大,孔隙度越小,浑水颗粒在粗粒土中运移也越困难,土柱填充性就越差;水头加剧了颗粒在土柱内部运移的速度,但也加速了其在顶部的沉积并封堵;S型时土柱0~2cm渗透系数下降速率最大,封堵时总体渗透系数最小,2cm以下相对孔隙率及随深度逐渐减小;S-I和I型土柱下部渗透系数明显滞后于上部,相对孔隙率存在临界深度(约为4~6cm);P型时土柱整体相对孔隙率基本无变化。

Pharmacokinetics of flunixin meglumine （FM） was investigated in 14 healthy pigs following single intravenous （i.v.） and intramuscular （i.m.） administration of the drug at the dosage of 2.2 and 1.1 mg kg-1. Blood samples were collected at different intervals after administration, and concentrations of FM were determined by HPLC method with a limit of detection of 0.1μg mL-1. The FM concentration-time data were fitted to a two-compartment open model after single i.v. dosing in pigs. The main pharmacokinetic parameters were as follows： tl/2a, 0.49 ± 0.03 and 0.58±0.07 h; tl/2β, 6.28±0.13 and 7.37 ±0.59 h; V/F, 0.01 ±0.001 and 0.01 ±0.002 L kg-1; CL, 0.01 ± 0.002 and 0.01 ± 0.002 L h-l; AUC, 237.73 ± 52.46 and 147.71 ± 36.76μg h-1 mL-1. The drug concentration-time data were fitted to a two-compartment model with first-order absorption after single i.m. administration in pigs. The main pharmacokinetic parameters were as follows： t1/2α, 0.90± 0.07 and 0.86±0.10 h; t1/2β, 8.79±0.85 and 9.60±0.10 h; V/F, 0.02±0.004 and 0.02±0.003 L kg-1; CL, 0.01±0.002 and 0.01 ±0.003 L h-l; AUC, 174.63 ± 45.84 and 112.42 ± 31.19 pg h-1 mL 1. The results of the present study showed that FM was rapidly absorbed, extensively distributed, and slowly eliminated in pigs. The drug was completely absorbed after single i.m. administration and a good bioavailability in pigs.

This study addresses the problem of jointly optimizing the transmit beamformers and power control in multi-user multiple-input multiple-output （MIMO） downlink. The objective is minimizing the total transmission power while satisfying the signal-to-noise plus interference ratio （SINR） requirement of each user. Before power control, it uses the maximum ratio transmission （MRT） scheme to determine the beamformers due to its attractive properties and the simplicity of handling. For power control it introduces a supermodular game approach and proposes an iterated strict dominance elimination algorithm. The algorithm is proved to converge to the Nash equilibrium. Simulation results indicate that this joint optimization method assures the improvement of performance.

We propose a scheme to probabilistically teleport an unknown arbitrary three-level two-particle state by using two partial entangled two-particle states of three-level as the quantum channel. The classical communication cost required in the ideal probabilistic teleportation process is also calculated. This scheme can be directly generalized to teleport an unknown and arbitrary three-level K-particle state by using K partial entangled two-particle states of three-level as the quantum channel.

We present a scheme for teleporting an unknown arbitrary two-particle state from a sender to either one of two receivers. The quantum channel is composed of two partial entangled three-particle GHZ states. An unknown arbitrary two-particle state can be perfectly teleported probabilistically if the sender performs two generalized Bell-state measurements and each receiver introduces an appropriate unitary transformation with the help of the other receiver's Hadamard operations and simple measurements.

Since the empirical mode decomposition （EMD） lacks strict orthogonality, the method of orthogonal empirical mode decomposition （OEMD） is innovationally proposed. The primary thought of this method is to obtain the intrinsic mode function （IMF） and the residual function by auto-adaptive band-pass filtering. OEMD is proved to preserve strict orthogonality and completeness theoretically, and the orthogonal basis function of OEMD is generated, then an algorithm to implement OEMD fast, IMF binary searching algorithm is built based on the point that the analytical band-pass filtering preserves perfect band-pass feature in the frequency domain. The application into harmonic detection shows that OEMD successfully conquers mode aliasing, avoids the occurrence of false mode, and is featured by fast computing speed. Furthermore, it can achieve harmonic detection accurately combined with the least square method.
