Constitutional formula (i) of heat resistance poly andPROBLEM TO BE SOLVED: To obtain a highly heat-stable heat-resistant poly-α,α-difluoro- paraxylylene film through polymerization by chemical vapor deposition by using a synthesized tetrafluoro-[2,2]-paracyclophane as the starting material and ...
and wear resistance. Their corrosion resistance is better than that of stainless steel; their wear resistance is better than that of stainless steel and Ti alloys; but their plasticity and workability are lower than those of stainless steel and Ti alloys. They were initially used for cast alloys...
In such tests, energy input is usually achieved by supplying a current over a known electrical resistance. For experiments on early-age cement pastes, the impact of exothermic hydration reactions occurring during measurement should be considered, e.g., by adjusting measured step changes in ...
This paper presents derivation and solutions of newly derived second-order and higher-order multipole formulas for calculating borehole thermal resistance and total internal thermal resistance of single U-tube ground heat exchangers. A new and simple form of the first-order multipole formula is also ...
摘要: PROBLEM TO BE SOLVED: To provide a tube for a heat exchanger excelling in corrosion resistance, and the heat exchanger excelling in corrosion resistance at a joint part of the tube with an external fin while the tube itself and the external fin itself have high corrosion resistance....
zones (LCZ-10 heavy industry) show less resistance to the HI index—they rise faster in the mornings and fall slower in the afternoons/evenings. Fig. 16 HI index in periods of heat wave by LCZ Full size image Figure17, using the stress index scale established in Table1, reports the ...

The model is capable of undertaking fire resistance analysis for beams exposed to any given fire time temperature curve. Various strain components including mechanical strain, thermal strain, and creep strain for both concrete and reinforcing... VKR Kodur,MB Dwaikat - 《International Journal of Conc...
These include the heat transfer through the fluid films (inside and outside), conductive heat transfer through the wall as well as the resistance of fouling deposits on the both sides. Accordingly, the following relation can be used to calculate the overall heat transfer coefficient for a ...
The model has four thermal parameters: (i) the per unit area thermal resistance between the internal air and the thermal mass (R1); (ii) the per unit area thermal resistance between the thermal mass and the external air (R2); (iii) the heat capacity of the wall (C); and (iv) the...
