The objective evaluation of image quality is very important for many image processing applications. Compared with other
existing algorithms, the biggest advantage of structural similarity model（SSIM）is that it is based on image structure distortion, and it
is highly consistent with human perception. Through in-depth study of the SSIM algorithm, it is found that it is difficult to clearly
identify the details of the image distortion with SSIM's defects. In this paper, a new SSIM algorithm is proposed to improve the
resolution of SSIM index map. The image resolution of SSIM-Map's index plan can be elevated with the method of changing portion
circularly. The experimental results show that the improved SSIM is more consistent with human visual system than original one, and
the accuracy of texture distortion is higher.

Advanced stellar population synthesis（ASPS）was used to study the color- magnitude diagrams of globular clusters
Hodge11, NGC1466, and NGC2257, which were observed by the Hubble Space Telescope（HST）in the Large Magellanic Cloud.
Without the consideration of errors in the observation, the distance modulus, color excess, metallicity, age, star burst number, binary
fraction, and star formation history of clusters were determined through fitting. The result shows that the three star clusters are old（with
average age of more than 14 Gyr）, and of a metallicity Z of 0.000 3. All of them are shown to be like single stellar populations and have
about 60 percent binaries. It is shown that ASPS fits to the observations better than traditional models.

aqueous extracts for providing a theoretical basis for the research and development of natural anti- caries drug. Methods:
Demineralizated enamel cultured by chemical reagents was used as model. With water as the extract, raw and ripe tea with 96，48，24，
12，6 mg/mL were used as test solution. 20 mg/mL NaF as the positive control group and deionized water as the negative control group
were divided into 12 groups and observed by scanning electron microscopy after pH extracorporeal circulation. Results: With the
increasing concentration of raw and ripe tea, the sediments on enamel surface were more uniform and compact and a large number of
regular crystallization generated when the concentration reached up to 96 mg/mL, and ripe tea group had more and thicker sediments
than raw tea; NaF group also had a lot of sediments, but was not compact; deionized water group only had a few sparse sediments with
uneven surface, and had little difference after demineralization. Conclusion: Raw and ripe Pu'er tea aqueous extract had the
remineralization effect on artificial demineralized enamel, but the low concentration was ineffective.

An indoor hybridization experiment by forced mating between two grasshoppers: Caryanda macrocercusa and C. cultricerca
were carried out. Results showed that the reciprocal crosses in the two species could produce fertile progeny F1; these differential
characters of F1 same as F2 were intermediate between the parents. The results indicated that the reproductive isolation between C.
macrocercusa and C. cultricerca was not yet formed. The two nominal species were the different subspecies of the same species. The
heredity of the differential characters didn't conform to the single-gene dominant genetic law.

With the species Atractomorpha sinensis as an outgroup, the phylogenetic relationships of 37 species belonging to 10
genera from 4 subfamilies（Caryandinae, Oxyinae, Podisminae and Melanoplinae）of Catantopidae were reconstructed based on COⅠ
gene 538 bp sequence data. The results suggested that: 1）the phylogenetic relationships among 4 subfamilies can be expressed as
（（（Caryandinae, Oxyinae）Podisminae）Melanoplinae）; 2）Caryandinae was supported as a monophyletic group; 3）the monophyly of
Canyanda and Longchuanacris can not be supported, but the two belong to the Caryandinae; 4）the monophyly of C. viridis species
group was supported which indicated the rationality of merging the Qinshuiacris into the Caryanda genus.

Objective: To compare the morphological characteristics of two sibling species of chigger mites: Leptotrombidium
rubellum and Leptotrombidium deliense. Methods: 100 identified larvae of two mite species（L. rubellum and L. deliense）with clear
structure were collected from the body surface of Asian house rat, Rattus tanezumi（R. flavipectus）, whose morphological structure were
observed and measured under a microscope for analyzing the morphological difference between two sibling species. Results: L.
rubellum had a quadrate-like scutum（SB<AP）, but L. deliense had a rectangle-like scutum（SB>AP）, and the difference between
them had statistical significance（P<0.01）. The SD, SB range of L. deliense is rather wider, and its SD, SD width/length, SB, PSB,
PW/AP, PW value were all slightly higher than L. Rubellum（P<0.05）. Conclusion: The two mite species are very close to each other
morphologically with tiny differences. Compared with SB<AP in L. rubellum, the difference of L. deliense is SB>AP, and this difference
can be used as the key evidence to differentiate the two mite species.

and 3 mg/m3 concentrations in a simulated indoor formaldehyde polluted decoration environment, and the absorption capacities as the
evaluation index were compared and ranked based on the absorption rate per leaf area after 24 h formaldehyde treatment. Meanwhile,
the chlorophyll content and other physiological and biochemistry index were measured to assess those plants' physiological responses to
formaldehyde stress. The primary conclusions are as follows:（1）The results showed that the capacities of different plants in purifying
formaldehyde were different, and under the concentration of three kinds of formaldehyde treatment, the Cremanthodium delavayi and
Bergenia purpurascens were better than Reineckia carnea, Murdannia nudiflora and Roscoea cautleoides for their purifying capacities.
（2）The tolerance of different species to formaldehyde stress were different. According to formaldehyde purifying capacity and the
tolerance measured in the experiment, Cremanthodium delavayi and Bergenia purpurascens had both higher purifying capacities and
higher tolerance.（3）Wild plants have a great potential in purifying formaldehyde gas.
