Study on residential quarters’ water supply and drainage design of expressway service area Junjun Zou1,a; Qiong Hu2,b. 1 Research Institute of Highway of the Ministry of Transport, Beijing, China, 100088 2 Beijing Construction Engineering Safety & Quality Central Supervision Station Beijing, China, 100073 ajj.zou@rioh.cn, b,277186941@qq.com Keywords: Expressway service area; residential quarters’ water supply and drainage; pipe materials’ selection; pipe connection; pipe arrangement and laying Abstract.
Outdoor water supply pipeline overburden depth should be based on the depth of soil freezing, vehicle load, the pipe material and crossing situation.
When outdoor drain pipes are connected, inspection wells with brick, stone and concrete materials should be set.

The paper proposed a dynamic optimization method, which aimed at maximization of material removal rate.
And the maximum of material removal rate, 81 mm3/s, was obtained.
But the material removal rate obtained by PSO is 81(mm3/s), which verifies the PSO under the condition of chatter-free.

Introduction Glass-ceramics are forward looking materials for modern technology.
An important group of glass–ceramics of high commercial value are Li2O-Al2O3-SiO2 (LAS) glass-crystalline materials.
Experimental 2.1 Preparation Analytical grade chemicals agent were used as starting materials in this study.
The raw materials were SiO2, Al2O3, Li2CO3, Na2CO3, KNO3, Sb2O3, NH4H2PO4, MgO, TiO2, ZrO2, ZnO, H3BO3 and Nd2O3.
The desired amounts of the raw materials were melted in an electric furnace at 1650℃ for 3 h under the heating rate of 10℃ min-1 until a bubble-free liquid was formed, and then the melt was cast in a pre-heated mold.

The materials presented in the article were obtained within the framework of the RFBR grant No. 17-48-630694 "Development of a physical model of the mechanism of thermoplastic hardening of materials operating under high temperatures and alternating loads".

In order to effectively reduce the comprehensive energy consumption of the refrigeration system so as to achieve the purpose of energy saving and emission reduction, from a practical point of view, this design studied cold storage refrigeration system’s exhaust heat recovery device and its applications, which fully recovered the exhaust sensible heat of refrigeration system and combined with solar collector’s work to provide energy for materials drying.
When ambient environment condition and refrigeration system’s exhaust temperature is high, the recovered sensible heat of the device's refrigeration system can provide dried energy for drying materials, so as to achieve the open cycle of waste heat recovery.

It is also a promising element for X-ray scintillators because its luminescence output and afterglow are comparable to or better than those materials currently in use.
The application of polymer assisted rapid synthesis of inorganic solids using organic compounds are controlled synthesis of inorganic nano and microcrystals with specific size, shape, structure and free dense agglomeration is of fundamental significance in modern material science.
The X-ray diffraction measurements were made using JEOL (JDX 8030)-X-ray diffractometer using Cu Kα radiation with a scan rate of 2o/min to identify the crystalline phase of the synthesized materials.

It also provides materials with unusual combinations of properties [8].
Materials and Experimental TPU (PEARLTHANE 11T80) with a hardness of Shore A80 was purchased from MERQUINSA Company.
In blending two or more polymer, too high a processing temperature also causes the materials (especially the NR) to degrade from oxidation.

It is shown that use of the covering materials containing quantum dots can significantly increase yields.
Such materials are characterized by a much lower level of scattering than a powdered materials or dispersed phosphors.
Some results of the tests to be vegetative materials are given in Table 4.
