＜正＞In this paper,an accurate and computationally implicit three-dimensional finite-difference time-domain method based on the unconditionally stable Crank-Nicolson scheme（3-D CN-FDTD） is *** numerical performance of the 3-D CN-FDTD method is demonstrated through numerical *** accuracy of this method,the ADI-FDTD method and traditional FDTD schemes are compared.A good agreement is obtained between the data computed with the 3-D CN-FDTD schemes by using time steps greatly exceeding the Courant-Friedrich-Levy（CFL） limit and the data computed with the explicit traditional Yee FDTD schemes.

In the impact melt breccia(IMb) of Sayh al Uhaymir(SaU) 169,the most KREEP-rich lunar meteorite to date(Gnos et al.,2004),clasts of a new type of lithologies were discovered,consisting of Ca-poor and Ca-rich pyroxenes(60.8 vol.%), ba-rich K-feldspar(27.9 vol.%),phosphates(5.6 vol.%),Nb-rich ilmenite(4.0 vol.%),zircon(1.2 vol.%) and minor sulfide (0.6 vol.%).These mafic lithic clasts are more enriched in KREEP component(～1500×CI) than the host meteorite and are highly enriched in *** are referred to as very high-K(VHK) KREEP lithology,and probably most close to the last residual liquid of the Lunar Magma Ocean without significant dilution by other Mg-rich *** fine-grained matrix of the SaU 169 IMb has very similar mineral chemistry to the VHK KREEP lithology,but contains abundant plagioclase with trace *** matrix shows decoupling of K from the REEP-like component;however,it cannot be simply interpreted by mixing the VHK KREEP lithology with anorthosites,which should have diluted the REEP-like component with the same proportion.

Oxidized low density lipoprotein (LDL) has been shown to inhibit the activity of platelet plasma mambrane Ca^2+ ATPase, and induce changes of factin in endothelial cells. Since the deformability of human erythrocytes are closely related to the calcium metabolism and the stability of cytoskeleton, the influence of oxidized LDL on plasma membrane Ca^2+ ATPase and plasma membrane fluidity were studied in human erythrocytes. Our in vitro experiments demonstrated that oxidized LDL, but not native LDL, inhibits the activity of Platelet Research Unit, Institute of Anatomy, University of Münster, Germany (Zhao b, Filler TJ and Dierichs R) Shanghai Fourth People's Hospital, Shanghai, China (Yu H) Department of biochemistry, University of Louisville, Kentucky, USA (Dean w)Ca^2+ ATPase in purified erythrocyte plasma membrane (Pbrane fluidity was detected in the erythrocyte plasma membrane exposed to native LDL and oxidized LDL as estimated by steady state by trimthylammonium diphenylhexatriene (TMA DPH) anisotropy, oxidized LDL did not affect the Ca^2+ ATPase by grossly changing the erythrocyte deformability probably by interfering the cytosolic calcium and then altering the cytoskeleton. The deformability of erythrocytes is important in microcirculation. A better understanding of the interactions between oxidized LDL, erythrocytes, platelets and endothelial cells can prevent cardiovascular diseases.

On the basis of the first year of neutral wind data measured by a meteor radar in wuhan,the tidal structure in the MLT is *** diurnal tide component is the dominant tide over wuhan,while the semidiurnal and terdiurnal tide are much *** to the variation of diurnal tide phase,the diurnal tide can be shown to propagate upward with vertical wavelengths between 30 and 50 *** diurnal tide amplitudes tend to show maximum values in spring and *** maximum zonal and meridional diurnal amplitudes are approximately 40 and 60 m/s,respectively.A comparison of the observed diurnal tide with GSwM00 values shows similar phase variations with height,but discrepancies in *** observed diurnal tide maximizes below 95 km,however the model amplitude increases with *** agreement of model and the observed diurnal amplitudes are good in summer and winter,but in autumn the model amplitudes are much greater than the observed *** analysis on semidiurnal tides indicates the maximum amplitudes in both zonal and meridional components are about 28 m/*** agreement between the model and the observed values of semidiurnal tide is not so good. The observed amplitude of the semidiurnal tide does not show any resemblance to the model *** observed amplitudes are greater than the model in spring and *** phase difference between the model and observed values may exceed 3 h in spring and winter.

As the anatomic structures,for example bone thickness,are different and the destruction of the membrane lining the inner ear can lead to a damage of organ functions,for example deafness or vertigo,the protection of soft tissue structures behind the ablated bone in skull base surgery is ***,a safer and more accurate Cochlear Implantation technology need to be developed *** the detection of the boundary between soft tissue and bone the laser bone abla-tion system which was based on the combination of laser,robotics,coaxial monitoring and vision navigation was developed for a micro surgery at the skull *** this the laser is guided across the ablation area by vision navigation *** this paper our laser bone ablation system and the first results of the boundary detection are described.

Nickel-,cobalt-,and iron-based(oxy)hydroxides comprise the most-commonly studied electrocatalysts for the oxygen-evolution reaction(OER)in alkaline solution.A fundamental understanding of composition-structure-activity relationships for mixed-metal Ni-Co and Ni-Co-Fe(oxy)hydroxides is important to guide the design of advanced OER *** we use cyclic voltammetry,chronopotentiometry,inductively-coupled plasma-optical emission spectroscopy,and in situ electrical conductivity measurements to characterize the properties and activity of various compositions of Ni-Co-Fe(oxy)hydroxides prepared by cathodic *** with previous studies,we find Fe is essential for the mixed-metal(oxy)hydroxides to achieve high OER *** the rigorous absence of Fe(achieved by using specially cleaned electrolytes),the most-active Ni-Co(oxy)hydroxide composition has an OER turn-over frequency only twice that ofpure Co(oxy)hydroxide,suggesting minimal synergism between the two *** addition of Co to Ni-Fe(oxy)hydroxides shifts the onset of electrical conductivity to lower potentials,but has little effect on the intrinsic OER activity,with the most-active Ni-Co-Fe(oxy)hydroxide having an OER turn-over frequency only -1.5 times that of the Ni-Fe(oxy)*** magnitudes of the electrical conductivities are similar for all the compositions ***-functional-theory-calculated projected density of states show a significant contribution of all chemical elements at the valence band edge of the mixed-metal oxyhydroxide electronic structure,demonstrating significant electronic hybridization between the *** calculations suggest the involvement of all the elements in modulating the electronic structure at putative Fe-based active sites that are probably located at edges or defects in the two-dimensional oxyhydroxide sheets.
