giant panda;habitat suitability;Maximum Entropy (MAXENT);nature reserve network;surrogate species
Many nature reserves are established to protect the habitat needs of particular endangered species of interest but their effectiveness for protecting other species is questionable. In this study, this effectiveness was evaluated in a nature reserve network located in the Qinling Mountains, Shaanxi Province, China. The network of reserves was established mainly for the conservation of the giant panda, a species considered as a surrogate for the conservation of many other endangered species in the region. The habitat suitability of nine protected species, including the giant panda, was modeled by using Maximum Entropy (MAXENT) and their spatial congruence was analyzed. Habitat suitability of these species was also overlapped with nature reserve boundaries and their management zones (i.e., core, buffer and experimental zones). Results show that in general the habitat of the giant panda constitutes a reasonable surrogate of the habitat of other protected species, and giant panda reserves protect a relatively high proportion of the habitat of other protected species. Therefore, giant panda habitat conservation also allows the conservation of the habitat of other protected species in the region. However, a large area of suitable habitat was excluded from the nature reserve network. In addition, four species exhibited a low proportion of highly suitable habitat inside the core zones of nature reserves. It suggests that a high proportion of suitable habitat of protected species not targeted for conservation is located in the experimental and buffer zones, thus, is being affected by human activities. To increase their conservation effectiveness, nature reserves and their management zones need to be re-examined in order to include suitable habitat of more endangered species. The procedures described in this study can be easily implemented for the conservation of many endangered species not only in China but in many other parts of the world.
The teaching building is located in the hot summer and cold winter region in China, after the teaching building built, due to use of row window and poorly considers the indoor comfort, it is very hot in summer. This study measured temperature, pressure of the teaching building and take the measurements as initial boundary conditions, use CFD software simulates the indoor air environment, thermal environment, the indoor thermal comfort index (PMV-PPD) of it, through the simulation, the indoor environment of the teaching building need a greatly improved, this study provides reference for the teaching building of ecological green design and improvement.
In order to guarantee the quality of laboratory animal, the nation codes regulate the pressure differential between indoor and outdoor, the air environment of the laboratory animal room under different pressure differential were simulated and analyzed under different wind velocity by simulation software in this paper. The follow conclusions were draw: (1) when face to outside natural wind, the maximal pressure is always on 1/4 to 1/3 heights to the top. (2) The relationship between the windward side maximal pressure and natural wind velocity is P(max) = 0.5842u(2) + 0.1099u - 0.0555. (3) The outdoor wind velocity of most area in China are less than 7m/s, for the isolated environment, it is safety when the pressure differential is +40Pa, but for the barrier environment, it is dangerous when the pressure differential is +20Pa, especially for the coastal area. When the laboratory animal room was built, the pressure differential should be adjust and accordance with the local wind velocity.
With medical image three-dimensional reconstruction software reconstruct three-dimensional model of the pelvic, Not only the principle of aiming device design is introduced, but also deduces the relationship between the measurements of pre-operative pictures and the angles of drilling ringers of the aiming device, and also compiles applied software for numeration, By the virtual prototype on aiming device of setting screws in acetabulum anterior column, the doctors can simulate the operative environment before operation, The study provides a dependable approach to advance the accuracy rate during operation of acetabulum anterior column setting screws deeply.

Screw heat pump units;Single-heat recovery with double-supply system;The heat pump units with three-supply system;Heat pump water heater with single-supply system;The heat pump unit comes with economizer;Heat recovery value
Introduce one cooler manufacturer's several heat recovery schemes of the screw heat pump units, such as single-heat recovery with double-supply system, the heat pump units with three-supply system, heat pump water heater with single-supply system and the heat pump unit comes with energy saver. Respectively calculate the energy saved by each heat recovery scheme. Point out the applicable climate and regions of each scheme and deduce the optimum amount of energy saved in ensured the screw heat pump units' main function circumstances.

With the continuous improvement of people's living standard, the demand of tourists about tourism product is growing. Tourism product packaging has a distinct regional and ethnic characteristics. In the packaging form, It is an important means of promoting the value of tourism products.() However, Touris m packaging industry not only to bring economic benefits to society at the same time, also bring the ecological environment and resource potential crisis. In the 1980s, human sustainable development strategy are put forward. The new concept of development is put forward with the changes of The Times, the demand of social economic development. The tourism products of green ecological packaging design began to be widely concerned. The sustainable development of green ecological design is an important subject of tourism industry, packaging industry in China. In the process of the research of the tourism product packaging, We should strictly carry out the general principles of the limit excessive packaging of clear rules. Four kinds of goods packaging, such as drink wine, cakes, tea and cosmetics. The packing layer is less than three layers. Food packing layer is no more than two layers. Beverage, wine, cake packing space is not more than 55% of goods volume, cosmetics do not exceed 50%, tea does not exceed 25%, food does not exceed 25%; Other food packaging gap should be no greater than 45%, packing layer should be not more than three layers.
