The reason why this project named “Red House” is from the building material on behalf of an era——red clay bricks.
The new section combines modern materials and form language, weird light, with anti-traditional aesthetic features, contrasting with the red-brick building.
We unified site guidance system, lighting equipment, landscape facilities, and sculpture sketches and materials, with particular emphasis on the unique red clay brick applications of “Red House”.

Vacuum membrane distillation renewable MDEA characteristics MDEA main physico-chemical parameters, seeing Materials section, part of it is showed in table 1.
Experiment Experimental materials.Polypropylene hollow fiber membrane module used in experiment is provided by Blue Cross, Tianjin Membrane Technology Co., Ltd.
Waste recycling rate and Permeate flux would be calculated by formula (1) and formula (2)[5-7]: (1) (2) Among them: In the formula (1), L means the saturated absorption capacity of MDEA solution, mol; L′ means saturated absorption capacity of regenerated solution, mol; In the formula (2), J means flux of membrane distillation, mol/m2·s; km means the vacuum membrane distillation coefficient, s.mol1/2/m·kg1/2, its value was determined by the parameters of hollow fiber membrane material in polypropylene[8].
The capacity of polypropylene fiber membrane used in experiment to bear the maximum temperature was about 80˚C, if exceeded the limitation the membrane material would be easy to damage.

Along with the quality requirements of injection molding products are improved continuously and the injection molding materials continue to emerge, more attention to optimization design of NRV is done.
Polycarbonate (PC) is chosen as the material of the simulation.
But when NRV3 is close nearly half, the pressure drops suddenly, because large material discharge emerged.
On the contrary, as the angle is 75 °, it is good for stressed of parts but bad for the flow of material, because of the relative large channel corner.

Over the past 20 years, there has been great interest in use of calcium phosphates, a principal inorganic constituent of natural bone, as scaffolding materials for bone tissue engineering [1,2].
Materials and Methods CPG with 0.6 of Ca/P molar ratio was prepared using CaCO3 and H3PO4 as raw materials.

AE (Acoustic Emission, referred to as AE) is a physical phenomenon of a material or structure of a local area or the overall external force or internal stress by plastic deformation or destruction of the occasion, of which the savings internal strain energy in the form of fast transient elastic waves release.
Eng Teik Ng and Gang Qi used wavelet analysis of the acrylic adhesive ceramic material fatigue failure in the acoustic emission signal generated[4].
Experimental conditions and parameters as the specific selection: work-piece material is 45 steel ; blade material is YT15 hard alloy ; Tool Types: end mills; sampling frequency : 2 MHz ; sampling length: 128000，continuous sampling; The above analysis, to make as shown in Table 1.1 experimental program, each of the condition collects 30 sets of data .

Materials and Methods The experimental material was a commercial steel rebar of HRB400E which was a vanadium containing high strength seismic rebar, its specifications was Ф16.
When material occurs solid phase transformation, the specific volume of the low temperature phase and the high temperature phase are often different, the phase transition should cause the volume change and destroy the purely linear relationship between temperature and the length, so the inflection point should appear by the discontinuous change.

The impeller is generally made of cast iron, bronze, titanium alloy and manganese bronze, as well as non-metallic material [1].
The integral titanium alloy impeller is very difficult to machine because of the complicated structure and the special titanium alloy material.
The cutter material has a great effect on machining of the titanium alloy impeller.
In the practical manufacturing, the hard alloy and the polycrystalline diamond are the ideal cutter material for machining of the titanium alloy [2].
