In this paper, the rheological, electrical and mechanical properties of silver paste with different blends of epoxy resin and polyester resin were studied. The thixotropy and thixotropy recovery rate of resin silver paste were studied by rheometer, and the effect of rheology on printing film was discussed. In situ curving resistance test method was used to monitor the change of thermal curing resistance of silver resin paste. The results showed that the content of epoxy resin in silver paste had great influence on the resistance. The adhesion strength of resin silver paste on Al2O3 substrate was evaluated by the thrust test method, and the thermal impact performance of resin silver paste was evaluated. The results showed that when the ratio of epoxy resin to polyester resin was 1:0.6, the viscosity of C-1 silver paste was moderate, the thixotropic recovery rate was 58.03% after 10 s, and the printing surface was flat. After curing at 200 ℃ for 30 min, the resistance is about 2 Ω, the adhesion strength is about 10 N/mm², and the adhesion strength is not significantly deteriorated after thermal shock at 260 ℃. The comprehensive performance is better, and it is suitable for the process requirements of electronic components. [ABSTRACT FROM AUTHOR]

Objective To investigate the anxiety symptoms and influencing factors, among community- dwelling adults in Shanghai, so as to provide references for the prevention and control of community mental health and the formulation of mental health policy. Methods We used a cross-sectional design and a structured questionnaire to investigate individual characters and anxiety symptoms. The structure questionnaire was composed of basic personal conditions and mental health service information, anxiety symptoms and depressive symptoms, influencing factors for anxiety symptoms among community residents in Shanghai were analyzed with Hierarchical Logit regression based on Anderson Behavioral Model of Health Service (P＜0.05). Results The prevalence rate of anxiety symptoms was 11.1%.The factors that were significantly related to anxiety symptoms were the predisposing factors of education, occupation, religion and the status of government aid; the enabling factors of regular mental health resources; and the need factors of anxiety symptoms were depressive symptoms. Conclusions The study shows a high risk of anxiety discords among adult residents dwelling in communities in Shanghai, and the comorbidity of depressive symptoms and anxiety symptoms is very serious. The main influencing factors include sociodemographic characters, community mental health resource. This study highlights a need for efforts to reduce the incidence of anxiety and other common psychological disorders. As early as possible, anxiety symptom screening should be included in the community mental health prevention service system. The key population should be focused. [ABSTRACT FROM AUTHOR]

In order to study the shear strength and related parameters of coal structural planes from Jincheng an-thracite coal, some direct shear tests under different normal stresses were carried out on coal samples with structural planes from No, 3 coal seam of Sihe mine, and also the three dimensional photogrammetry of the structural surface topography was carried out. The tests obtained some experimental values and estimated values. The test results show that under a low normal stress level, the stiffness range of coal structural plane is 13-39.2 GPa/cm, and the range of shear stiffness is 3.1-26.6 GPa/cm. Under a moderate normal stress level, the stiffness range of coal structural plane is 13.8-62.0 GPa/cm, and the range of shear stiffness is 4.3-18.2 GPa/cm, The average cohesion of coal structural plane is 0.67 MPa, and the average peak friction angle is 37 degree. With the increase of normal stress, the normal stiffness, shear stiffness and shear strength of the structural plane also increase. The test values provide a reference for the parameters in numerical simulation. Through the comparison between calculated shear strength and experimental shear strength, the JRC-JCS model can be used to predict the shear strength of the structural plane. [ABSTRACT FROM AUTHOR]

To clarify the impact of bonding stiffness on bolts support effectiveness for stratified roof, the concept of bonding stiffness and its realization way in software FLAC3D were firstly introduced, then the roadway model with stratified roof was established using the interface elements of FLAC3D, and emulational bolts model was constructed by means of integrating pile structural elements with liner structural elements, whose pretension imposing method was also put forward. Based on these, the support effectiveness of different bonding stiffness for stratified roof were analyzed under the condition of in-situ stress. The results show that: Under certain conditions, the bonding stiffness determines the resistance-increasing characteristics of bolts, which vary from slowness to rapidness with the increase of bonding stiffness. Bolts support has definite control effectiveness for the separation of stratified roof. The greater the bonding stiffness,the better the control effectiveness. Supporting stress field of bolts can improve stress state distinctly, diminishing even eliminating the distribution of tension stress. The improving effect would get better if the bonding stiffness increases. The bolts body would experience bending deformation under the influence of interlayer sliding of beddings, but the deformation degree would be relieved with the increase of bonding stiffness. In consideration of the importance of bonding stiffness, the technical approaches of improving the bonding stiffness were put forward, including optimizing the shape of bolts body, improving the contact condition of surrounding rock, strengthening the bonding behavior of anchor agent, and enhancing the installation quality of anchor agent.

To investigate the influence of joints on uniaxial compression behavior of jointed coal, the synthetic coal mass specimen was first constructed based on the in-situ measurement of joints and numerical parameters calibration tests. Then the numerical uniaxial compression tests on intact coal and jointed coal with REV size under different loading orientations were conducted. Finally, the influence mechanism of joints on the mechanical behavior of jointed coal and the fracture formation mechanism were analyzed. The study shows that:(1) The constructed synthetic coal mass model can represent the jointed coal investigated, with the REV equaling to 1.0 m×1.0 m×2.0 m. (2) Joints weaken the UCS and elastic modulus, but increase the deformation of jointed coal under uniaxial compression, with the weakening/increasing degree depending on the relation between loading orientations and joints. (3) Joints determine the failure mode of jointed coal under uniaxial compression. The jointed coal by splitting fracture parallel to loading directions, with different splitting geometries under different loading orientations. (4) The contribution ratio of matrix failure and the contribution ratio of joints activation were put forward, which can be used to quantitatively evaluate the contribution degree of matrix failure and joints activation to the failure of jointed rock, respectively. (5) The joint parallel to loading orientation is converted to activated pre-existing fracture under the effect of loading force, from the end of which grow the wing crack, both of which form the compression-induced tension fracture composition. For jointed coal containing nonpenetrating joints, the splitting fractures are formed by the coalescence of fracture compositions. For the coal mass containing through joints, the splitting fractures are formed only by the through activated pre-existing fractures. [ABSTRACT FROM AUTHOR]
