The detailed term accounting(DTA)approximation for the line absorption and the average atom(AA)model for bound-free and free-free absorption are used to calculate the radiative opacity of high-power laser-produced plasmas in local thermodynamic equilibrium(LTE).The spectral resolved opacities of Al plasmas are calculated at the temperature and density of 40 eV and 0.0135 g/cm^(3) and 58 eV and 0.02 g/cm^(3).Rosseland and Planck mean opacities are obtained by integrating the spectral resolved opacities with Rosseland and Planck weighting *** results show that the Rosseland mean opacity is very sensitive to the detailed *** opacities under the same plasma conditions are also obtained by using a completely pure AA *** results from the DTA and pure AA models are then compared.

This paper provides the notes on the supertribe Brachineuridi and a review of the diagnostic characteristics of the genus Cingola Fedotova ＆ Sidorenko with two new species from China. The generic diagnosis of Cingola is revised to give an adequate description and a key to males of all known Cingola species is given. Two new species, Cingola eircularis sp. nov. from Henan, Jiangxi and Yunnan, and Cingola ceratodicrata sp. nov. from Guizhou are described and illustrated. The type specimens were deposited in the Institute of Entomology, College of Life Sciences, Nankai University, Tianjin, China.

We present a detailed analysis of the soft X-ray emission of 3 C 445 using an archival Chandra High Energy Transmission Grating（HETG） spectrum. Highly-ionized H-and He-like Mg, Si and S lines, as well as a resolved low-ionized Si Kα line, are detected in the high resolution spectrum. The He-like triplets of Mg and Si are resolved into individual lines, and the calculated R ratios indicate a high density for the emitter. The low values of G ratios indicate the lines originate from collisionally ionized plasmas. However, the detection of a resolved narrow Ne X radiative recombination continua（RRC） feature in the spectrum seems to prefer a photoionized environment. The spectrum is subsequently modeled with a photoionization model, and the results are compared with those of a collisional model. Through a detailed analysis of the spectrum, we exclude a collisional origin for these emission lines. A one-component photoionization model provides a great fit to the emission features. The best-fit parameters are log ξ = 3.3^＋0.4-0.3 erg cm s^-1, n H = 5^＋15 -4.5× 10^10 cm^-3 and NH = 2.5^＋3.8 -1.7× 10^20 cm^-*** to the calculated high density for the emitter, the measured velocity widths of the emission lines and the inferred radial distance（6 × 10^14-8 × 10^15 cm）, we suggest the emission lines originating from matter are located in the broad line region（BLR）.

Combining metal to form metal phosphide is a promising strategy to address the fast capacity decay of P rooted from its low electronic conductivity and large volume changes upon cycling. Cu_(3)P, which possesses a high theoretical gravimetric and volumetric capacity of 363 m Ahág^(-1) and 1028 AháL^(-1) and reasonable volume expansion of 156% during sodiation, was investigated as anode material in SIBs. Hollow-structured Cu_(3)P electrode delivers an initial de-sodiation capacity of * 159.0 m Ahág^(-1) with high capacity retention of ~85.1% over 50 cycles at 0.2 C rate and exhibits good rate performance,retaining 70% of the capacity when the current density increases from 0.2 C to 1.6 C. A 3 V-class full cell consisting of P2-Na_(2/3) Ni_(1/3) Mn_(1/2) Ti_(1/6)O_(2) cathode and Cu_(3)P anode was also assembled, which could achieve an energy density of ~189.3 Whákg^(-1)(based on the mass of both electrode materials) and average discharge voltage of~2.91 V when cycled in 1.0-4.3 V at 0.1C.
