In order to study ship type of small and medium size tailing suction hopper dredger (TSHD), a comparative analysis targeted to Pallieter and Hangjun4009 is carried out. By comparing main dimensions, hull lines and principal characteristics, the usability of TSHD with a bigger block coefficient and a bigger width/draught ratio is studied. Based on calculation of wave-making resistance coefficients, the effect of special bulbous bow on wave-making resistance is studied.

We report a compact all-solid-state mid-infrared optical parametric oscillator with wide tenability using periodically poled 5 mol % MgO-doped LiNbO3 with a multiple-channel structure design and pumped by a compact diode-pump solid-state laser operating at 1.064 µm. Wide tunability from 1.44 to 1.58 µm at the signal beam wavelength and from 3.28 to 4.11 µm at the idler beam wavelength was achieved by both varying the temperature and translating the crystal through the resonator and the pump beam with no realignment required. The tuning range is in the atmospheric transmission window.

Exploration and development of the deep part coal resource have important strategic meanings for Chinese economic. However, the seismic of strata in deep part is always suffering from the decline of resolution. To overcome this problem, we propose a method to improve resolution of seismic data by spectrum whitening in time-frequency domain. Compared with conventional algorithm, our method enhances every point of a seismic signal according to the spectrum in a local region. The application results of the real data show our method could broaden bandwidths of seismic data and make strata in deep part more distinct and continuous.

A new kind of venturi-swirler-combined scrubber was developed. This venturi-swirler-combined scrubber is composed of shuttle-typed components and swirler. These shuttle-typed components were assembled to comprise a honeycomb-typed structure gas passages similar to a contraction section, a throat section and an expansion section of venturi. By Sodium calcium Dual alkali scrubbing desulphurization method, the experimental study on desulphurization efficiency of venturi-swirler-combined scrubber was also carried in the pilot system. The effects of operational parameters such as liquid-gas ratio, SO2 concentration, regeneration liquid pH, sodium ion concentration, sulfate ion concentration on desulphurization efficiency were discussed.

Vacuum solar receiver is the key component in parabolic trough solar system. Due to different expansion increment between metal absorber and glass, corrugated expansion joint (metal bellows) is necessary to compensate the extra expansion increment. The mechanical and thermal properties of metal bellows have significant influence on the reliability and heat loss of solar receiver. Recently, China's first high temperature vacuum receiver has been developed and produced by Southeast University and Sanle Electronic Group. This paper analyzes the fatigue properties from displacement compensation, stress assessment and axial elasticity. First, varies stresses of metal bellow when compensating for axial displacement is calculated, and the reliability of bellow is analyzed from the point of stress condition and fatigue life. Because metal bellows will reduce the effective absorbing length, metal bellow should be shortened under the precondition of enough axial compensation. Second, the axial compensation of bellow is a primary factor in design. This paper deduces a simple equation to calculate the maximum axial compensation of single wave for the toroidal bellows, and the calculation proves the compensation of the bellow designed meets the receiver requirement. Finally, the experimental measurements verify it has a good fatigue property.

This paper takes Wuxi as a case study and analyzing the characteristics of urban expansion from the viewpoint of urban scale and urban structure, here we emphasize that urban spatial expansion is not only build-up area increase, but also the change land use structure. We further explain the reasons that have given rise to these changes. We conclude this case study with some observations on the impacts upon Wuxi's environment in the wake of the rapid urban expansion during the last three decades.

Based on the monitoring data of June 2009 from Xinxue River Constructed Wetland, Shandong, China, the research was done to reveal the variations of COD, NH3-N, TN and TP in multistage series constructed wetland system. The results showed that the constructed wetland had a fairly good purification efficiency to the polluted water of Xinxue River, and the concentration of various pollutants gradually decreased along the technological process; the removal rate of COD, NH3-N, TN, TP was respectively 55.1%, 47.2%, 83.7% and 56.3%; in the retention pond and various stage of wetland, the removal rate of various pollutants was respectively 4.2∼ 13.8% for COD, 2.5∼13.0% for NH3-N, 0.1∼ 29.5% for TN and −25.0∼ 25.0% for TP; because of the matrix releasing phosphorus to water, the effluent TP concentration of the fifth stage wetland is higher than the fourth stage.

Urban planning has transformed from technological means in the traditional ideas to the public policy, because it distributes the public interest according to the spatial resources' disposition. It is explicitly stipulated that the urban planning must ask for the opinions of the public and the experts according to the city and countryside plan law, so the advancement of the plan public participation has become the mutual recognition. The author tracked all the process of the compilation of the Ningbo High-tech Industrial Zones regulatory plan and surveyed the condition of the public participation by means of questionnaire survey, stochastic interview and so on, when the plan was announcing. The prime features and initial causes have been analyzed from the Point of Empirical Research in the urban planning compilation stage, at last the author put forward the proposals how to advance the public participation in the urban planning compilation under the present decision tree.

The performance of dynamic adsorption and the effects of height of filler, MB initial concentration and flow rate on the breakthrough curves were investigated by the dynamic adsorption experiment of the filler column. The results showed: Aged-refuse can effectively adsorb MB in the water, with the increase of filler height, the breakthrough point in the curve move toward the right and the breakthrough time is prolonged. Whereas, with the increase of flow rate and MB initial concentration, the breakthrough point of the curve shifts toward the left and the breakthrough time is shortened. The adsorption process in the initial phase conforms to Adams-Bohart model. The effect of sorbent height on removal MB can be well described by BDST model.
