Effectofthree-bodyrecombinationandzero-phaseonquantumtunnelingoftriple-welltrappedBose-Einsteincondensatesby MU Ai-xia p.8

To modify three coupled Gross-Pitaevskii equations (GPEs) and to describe the dynamics of the system, the author used the method of three-mode approximation and discussed the macroscopic quantum tunneling in zero-phase on triple-well trapped Bose-Einstein condensates (BECs). The corresponding numerical results show that phase plays an important role in the system of triple-well trapped BECs. And in the zero-phase, most atoms are trapped in the middle trap, and in the other two wells atoms have been equal. At the same time, he finds that with the decreasing of scattering length, atoms increase in the amplitude. And in the process of quantum tunneling, resonance phenomenon occurs.

Lengthofcrackexpansionundercomplexstressstateby HE Yong, HUANG Xia p.14

Primary cracks exist in the internal of brittle rock materials. Under complex stress state, primary cracks and new branch cracks expand regularly. On the basis of existing research results, the authors established a crack expanding mode, and divided complex stress state into compression shear stress state and tensile-shear stress one. With the law of conservation energy and fracture mechanics method, they forged two crack expansion length formulas in each stress states, and also applied them into the analysis of unstable rock block’s stability. Thus they put forward a norm which can judge unstable rock block’s stability.

Key words: initial damage; expansion evolvement; stress intensity factor; elastic strain energy; mechanics of materials

Applicationofzero-watermarkingtechnologyinbinarytextimagesby HUANG Ting p.18

In recent years, the zero-watermarking technology is getting more attention for it can construct watermarks by only using the original data. To solve the contradiction between the transparency and robustness of digital watermarking, the author applied this technology into binary text images. The Timestamp mechanism can inhibit the interpretation attack. The Zero-watermarking simulation experiment based on the discrete wavelet transform (DWT) was structured in Matlab. And the results show that the algorithm has a strong anti attack capability and stable performance.

Key words: digital text watermarking; binary images; zero-watermarking; timestamp; discrete wavelet transform (DWT)

Surveyonlandcoverinformationextractingofmountaincitybasedonobject-orientedandmulti-scaletechnology:takingShengliluCommunityofYongchuanDistrictforanexampleby HUANG Xia, MU Feng-yun, LIU Xi, HE Shun-bing p.26

To extract land cover information from CBERS 02B HR image whose spatial resolution is 2.46 meters, the authors used object-oriented and multi-scale segmentation technology based on eCognition. Using multi-scale segmentation technique, they calculated the optimal segmentation scale on account of RMAS method. According to the results of segmentation, they created a knowledge base firstly, and then used the nearest neighborhood classification to extract land cover information, such as vegetation, water, houses, roads and other information. Finally, they used accuracy and stability to evaluate the classification results. It shows that this method can not only make better use of the spectrum of image, but also the texture, shape, size and other spatial information can be used effectively, especially in that of complex mountain city. In conclusion, the best segmentation scales for vegetation, house, water and roads are respectively 25, 20 and 15, and the average classification accuracy is up to 95.63%.

Landpricelawofrural-urbanfringebasedonMarkovmodel:takingBeijingasanexampleby GUO Li-bin p.41

With Markov chain theory, the author built a land price prediction mathematical model, and took the rural-urban fringe area of Beijing as an example, to conduct a quantitative analysis on the spatial variation characteristics and trend of land price. The calculation results showed that the changing trends of land price varied greatly from different directions in Beijing. It showed that Beijing city was in disequilibrium development process. Changes of land prices in the rural-urban fringe were more complex than those in the urban land, affected by more factors. Under the influence of multiple factors, forms the land price law that the land price in Beijing rural-urban fringe differs completely in different directions, estimated by Markov model.

Key words: Markov model; rural-urban fringe; land price; Beijing

Researchonthecharacteristicsofcollegestudents’adultattachmentby FANG Lei, TANG Qing-tao p.67

To analysis on adult attachment of college students, the authors selected 320 college students in Huaihua as subjects and used the experiences in close relationships-revised (ECR-R) scale to conduct a survey, based on the attachment theory. The results show that among the types of adult attachment, the fear type accounts for 50.9% of the total, the cold type is 21.5%, the safety type and the focus type is each 13.8%. Secondly, there is no significant difference in genders or professions for college students’ attachment. Thirdly, on adult attachment avoidance dimension, freshmen are significantly greater than juniors and seniors, and college students from rural areas score significantly higher than students from cities and towns. The last one, the students without love experiences in the two dimensions of avoidance and anxiety score significantly higher than the students with love histories.

Key words: attachment; college students; experiences in close relationships-revised (ECR-R) scale

Comparativeoncollegestudentswithgoodmentalhealthandthosewithpsychologicalproblemsinparentingstylesby SU Wen p.72

To explore the differences between the college students with good mental health and those with psychological problems (problem students) in parenting styles, the author used SCL-90 scale and EMBU questionnaire to conduct a survey on 351 college students from two higher education institutions in Yunnan Province. Then she got three results. Firstly, the parents of the problem students use far more parenting styles such as refusal, denial, punishment and interference, than those of college students with mental health. Secondly, the parents of the problem students use far more parenting styles such as authoritative type and authoritarian type. Thirdly, the fathers’ parenting styles of the problem students are inconsistent with those of mothers’. Thus she draws the conclusion that the parenting styles of the problem students are too harsh, and it is not appropriate between punishment and love.

Key words: college students; mental health; parenting styles
