(1)The proposed monitoring units are slave machines, they are installed in each ward locally, each monitoring unit would allocate 2 to 8 sensors according to the number of ward bed, and then handle with the collected temperature data, send the test results to the host PC at the same time.

The reasons are 1) The smaller stomata size decreases the amplitude of air convection and reduce the convection heat transfer efficiency; 2) The numbers of porosity cells grow reduce the radiation heat transfer efficiency.
The sizes of the spherical pores caused by decomposing the polystyrene grains are all smaller than 1.7 mm and decrease when small polystyrene particles are used.

is wave number and .
It is assumed that there exist volumes large compared to pore/grain sizes but small compared to wavelength and that each volume element is describable by the average displacement.

A number of urban rail transit lines built and put into use in succession [1].
Use the rubber roller to compacting the carbon fiber in the fiber direction steadily, making the resin overflow from both sides, ensuring close-grained without hole.

Although experimentally many occurrences of pillar-to-pillar collapse have been observed, other modes were also present in significant numbers, indicating a strong sensitivity of the pattern collapse to slight process variabilities.

When the hydrogen content of the workpieces is low, the microstructure of the workpieces has phase transition and grain refinement with the increase of amount of hydrogen, which leads to the improvement of the mechanical properties of the material and gradual decrease of its hardness.

., ceramics based on synthetic analogs for of titanate rock-forming minerals, is a more perfect material, which preserves its mechanical and chemical properties for a long time and can accept a large number of radioactive elements contained in high-level waste into the lattice.
The matrix completey encapsulates each separate block of perovskite, The grain size ranges from 15 to 25μm.

Introduction Landslides cause extensive damage to property and occasionally result in a great number of casualties .Among the many causes of landslides, those triggered by earthquake and heavy rainfall are the most common throughout the China.

An excitation yoke is made of two sheets of grain-oriented (GO) steel, each 0.35-mm-thick.
Its length is 1.90 m; diameter, 114 mm; and the number of windings (turns, N), 3533.

Introduction Equal channel angular pressing (ECAP) is an effective route to refining coarse-grain size into submicrometer or nanometer regime by means of large plastic shear deformation, which was first introduced by Segal [1].
The most advantage of ECAP is that the billet undergoes severe plastic deformation (SPD) but remains the same cross-sectional geometry so that it is possible to repeat the pressings for a number of passes in order to achieve a very high total strain.
