The two-parameter formulae, i.e. the nuclear softness formula and the power index formula, have been used to obtain the band head spin （I0） of the triaxial superdeformed （SD） bands in ^163Lu（1,2,3,4）, ^164Lu（1,2,3） and ^165Lu（1,2,3）, in the A - 160 mass region. The least squares fitting approach is used. The values of the root mean square （RmS） deviation among the computed and the measured experimental transition energies are obtained by calculating the model parameters. Whenever accurate spins are available, superb agreement is shown between the determined and the measured experimental transition energies. In comparison to the power index formula, the values of band head spin （I0） of the triaxial SD bands in ^163Lu（1,2,3,4）, ^164Lu（1,2,3） and ^165Lu（1,2,3） obtained by the nuclear softness formula are closer to the experimental data. The lowest RmS deviation is also achieved by the nuclear softness formula. hence, the nuclear softness formula works well for obtaining the band head spin （I0） for the triaxial SD bands in ^163Lu（1,2,3,4）, ^164Lu（1,2,3） and ^165Lu（1,2,3） in the A-160 mass region. The dynamic moment of inertia against hω is also studied.

The experimental rotational spectra of superdeformed（SD） bands of 130La, 131Ce（1,2）, 132Ce（1,2,3） and133 Ce（1,2,3） in the A～130 mass region are systematically analyzed with the four parameter formula, power index formula, nuclear softness formula, and VmI model. It is observed that out of all the formulae, the four parameter formula suits best for the study of the 130La, 131Ce（1,2）, 132Ce（2,3） and 133Ce（1,2,3） SD bands. The four parameter formula works efficiently in determining the band head spin of the 130La, 131Ce（1,2） 132Ce（2,3） and 133Ce（1,2,3） SD bands. Good agreement is seen between the calculated and observed transition energies whenever the accurate spin is assigned. In 132Ce（1）, the power index formula is found to work better than the other three formulae. The dynamic moment of inertia is also calculated for all the formulae and its variation with the rotational frequency is investigated.

1. IntroductionChina is entering an impressive era of grain production since its reform and opening up in 1978. At present, China feeds 22% of the world population with only 9% of the world＇s arable land [1]. Thus, China has become a leader in the global fight against hunger[2] . Grain production has increased dramatically, from about 3 × 10^8t in 1978 to 6.21 × 10^8t in 2016, which is an annual increase rate of 9% [3].

A novel semi-solid slurry-making process was developed, which was a controlled nucleation and growth technique using a specially designed rotational barrel. Experimental study was undertaken to investigate the effects of pouring temperature and rotation speed of barrel on the microstructure of A356 alloy. Localized rapid cooling, combined with vigorous mixing during the initial stage of solidification enhanced wall nucleation and nuclei survival. high nuclei density combined with a much gradual cooling afterwards led to the formation of the near-ideal semi-solid slurry under a large processing window for the pouring temperature. Primal. phase presented in mean equivalent diameter of 50-701μm and shape factor of 0.812-0.847, and featured zero-entrapped eutectic.

Low and medium carbon steels were aluminized by the pack aluminizing technique using halideactivated pure-Al and Fe-Al packs. The effect of mixture composition, aluminizing temperatureand time and C content of the steel substrate on the structure and thickness of the aluminidelayer, and on the oxidation resistance was investigated. The optimum oxidation resistance canbe achieved with a low carbon steel substrate when the intermetallic phases Fe3Al and FeAlform the surface of the aluminide layer. In this case, the Al concentration at the surface of thealuminide coating is at least ≥15 wt pct. Formation of high Al concentration phases (FeAl3 andFe2Al5) during aluminizing should be avoided as they tend to embrittle the aluminide layer andreduce its oxidation resistance.

Bacterial quorum sensing（QS） molecules are involved in the coordination of certain behaviors such as biofilm formation, virulence and antibiotic resistance. QS molecules（autoinducers） and their corresponding receptors have been recognized as important therapeutic targets for drug-resistant infections and biofilm-associated infections（BAI）. This study assessed the multiple biological effects of h.m.gentisic acid y-lactone（hgAL）, a furanone derivative. The anti-QS and anti-biofilm effects of hgAL against PAO1 strain were evaluated using CLSm, SEm, hPLC and other bioch.m.cal methods The results showed that hgAL could effectively inhibit the production of pyocyanin and extracellular matrix, as well as reduce the adherence ability and biofilm formation of Pseudomonas aeruginosa. Inhibition of virulence is attributed to the suppressive effect of hgAL on biosynthesis of 3-oxo-C12-hSLand C4-hSL（two kinds of QS signaling molecules in P. aeruginosa）. Our results support hgAL as a potential agent for prevention of BAI in the healthcare settings.

Experiments conducted to determine the effect of copper addition on the machinability of plastic mold steel, 4Cr16mo, were presented. The machinability of mold steel 4Cr16mo was visibly improved by adding Cu. The top wear of 4Cr16mo with copper was less than that without copper. The Cu-rich phase had the effect of a lubricant and the heat conductivity, which reduced cutting-tool wear, improved machinability, and increased the service life of the cutting-tool. Increasing of copper addition decreased the hot-working character of 4Cr16mo. The optimal hot-working parameters for 4Cr16mo with copper were determined by the tensile test and the compression test. The rate of deformation should be adopted as 0.6 s-1. The heating-up temperature, initial forging temperature, and terminal forging temperature were 1200℃, 1150℃, and 950℃, respectively.

The corrosion inhibition for carbon steel in circulating cooling water by modified lignosulphonate has been investigated using electroch.m.cal impedance spectroscopy technique. Results show that the inhibition efficiency of modified lignosulphonate GCL2 is a great improvement on that of lignosulphonate. The maximum inhibition efficiency of GCL2 reaches 99.21% at the concentration of 400mg·L^-1 at 303K. The corrosion inhibition of GCL2 is attributed to forming adsorption film on the metal surface for the electroch.m.cal impedance spectroscopy in GCL2 solution shows more than one ***,results also indicate that it is more efficient in stirring solution than in still solution for GCL2 because the constant of adsorption in stirring solution is much larger than that in still solution. The adsorption of inhibitor GCL2 follows Langmuir＇s adsorption isotherm.
