Authors: Zheng Ming Xing , Zhang Ai Hua , Xu Jing , Sun Yang
Published: September 2013

This study aims to validate a model of consumer acceptance for 3G use in China. It integrates the technology acceptance model (TAM) and satisfaction theory to examine plans to introduce third-generation mobile phones to second-generation mobile phone users. In addition, this study considers the effect of self-construal on the perceived usefulness, perceived ease of use, subjective norms, prior satisfaction with 2G/2.5G, and intention to use 3G. The empirical results of this study show that the technology acceptance model partially explains consumers intentions to adopt 3G technology. Although consumers perceive that 3G is easier to use, this does not directly influence them to use 3G. Prior satisfaction with their current model of phone does not influence consumers intention to use 3G. Moreover, self-construal has moderate effects on the relationship between perceived usefulness, subjective norms, and the intention to use 3G.

In the test, we adopted the method of potted plant cultivation to research that how the organic fertilizer influences on the growth of plants in the soil as regards to different concentration of lead pollution and analyze the transport of lead in soil and plants system. In each group, The root tolerance index (RTI) and transport factor (TF) of plant were analyzed. The results showed that the root of the plant had great effect on the lead pollution. After its root contacted lead, most of the lead were kept in root, rather than moving. The quantity of lead of plant including ground and underground were measured. The results showed that the quantity of lead in underground was too much higher than the quantity on the ground.

Wear loss is defined as volume, weight and length difference due to the wear process. In practice, measurement of wear loss is difficult because most parts of the machine have no simple shape and are not easy or even impossible to measure the changes of volume, weight or length. In this paper, a particular method of wear loss measurement based on computer image collection and analysis was developed to measure the length changes of some particular parts such as ball grooves of the muster clutchs release ring of a type of tracked vehicle. Macro-surface profiles of a worn surface of a groove on a release ring were taken by a digital camera first and were demarcated. Then worn scars of these digital photos were scaled in length by a computer image processing software of DT vision foundry. The geometrical relationship between wear length and depth was analyzed so that the wear depth was available as well. Results show that the length of the scar is 15.9 mm and the depth is 1.48 mm. Then the surface of the wear scar was measured by a type of 3D laser scanning machine and the points cloud was rearranged and edited by a reverse software of Surfacer. Results of 3D scanning show that the length of the scar is 15.7 mm and the depth is 1.56 mm, which is well consistent with the results of the method mentioned above. It demonstrates the effectiveness and economy of using the method of computer image collection and analysis for wear loss measurement.

In order to reduce the adherence of platelets to the pyrolytic carbon surface of cardiac valve prosthesis, micro patterns are textured on the surface by nanosecond laser. As the basement, the textured pyrolytic carbon then reacts with formamide and zinc by hydrothermal method for preparation of globular ZnO film. In the process, the formamide concentration should be 10%, temperature at 70°C and the time lasts for 24 hours. Subsequently, scanning electron microscope (SEM) is employed for observation of its characteristics and morphologies and Optical Contact Angle Measuring Device (OCA) for measurement of contact angles. The experimental results indicate that the ZnO film produced on the textured pyrolytic carbon surface is a globular structure, similar to dandelions and the contact angle with super-hydrophobicity feature is 155 o. So it is concluded that globular ZnO film makes the rough pyrolytic carbon surface endowed with the characteristic of super-hydrophobicity.

Sonochemical degradation of the antibiotics chloramphenicol in aqueous solution with sodium peroxydisulfate sulphate (SPDS) enhancement was investigated. The preliminary studies of optimal degradation methodology were conducted with sole SPDS, cobalt activated SPDS (SPDS/Co2+), ultrasonication with SPDS (SPDS/US) and ultrasonication with cobalt activated SPDS (SPDS/Co2+/US). The effect of the initial pH values of the aqueous solution on the sonochemical degradation rate of chloramphenicol was also investigated. The results showed that the sonolysis of chloramphenicol can be accelerated remarkably by adding SPDS and the efficient treatment method for treating the chloramphenicol wastewater was ultrasound coupled cobalt activated SPDS. The ultrasonic degradation rate constants in acidic water are higher than those obtained in neutral or basic aqueous solutions.

A unsymmetrical photochromic diarylethene, 1-(2,5-dimethyl thiazole)-2-[4-(2-cyanophenyl)-3-thieny} perfluorocyclopentene (1a),was synthesized, and its optoelectronic properties were also investigated in detail. The results showed that this compound exhibited reversible photochromism, changing from colorless to orange red after irradiation with UV light both in solution and in PMMA amorphous film.The open-ring isomer of the diarylethene 1 exhibited relatively strong fluorescence at 432 nm when excited at 384 nm. The fluorescence intensity declined along with the photochromism upon irradiation with 297 nm light.The diarylethene exhibited a fluorescence switches along with the photochromism from open-ring isomers to closed-ring isomers. When irradiated by UV light, the photocyclization reaction was occurred and the emission intensity of the diarylethene decreased significantly, due to producing the non-fluorescence closed-ring isomers. The back irradiation by appropriate wavelength visible light regenerated its open-ring isomers and recovered the original emission intensity.
