This review holistically scopescurrent advances in this field, while giving special attention to critical factorsthat affect thermal conductivity in polymer composites as well as the thermalconduction mechanisms on how to enhance the value. This review coverscritical factors such as inter...
The resistance of a conductor depends onthe cross sectional area of the conductor, the length of the conductor, and its resistivity. It is important to note that electrical conductivity and resistivity are inversely proportional, meaning that the more conductive something is the less resistive it is...
Ambient temperature andhumidityaffect the PCB’s ability to dissipate heat Optimizing Aluminum PCB Thermal Conductivity To maximize the thermal conductivity of aluminum PCBs, designers and manufacturers should consider the following strategies: Choose high-purity aluminum or alloys with good thermal properties...
Thermal conductivity, also called heat conduction, is the flow of energy from something of a higher temperature to something of a lower temperature. It is different from electrical conductivity, which deals with electrical currents. Several factors affect thermal conductivity and the rate that energy ...
It was found that the carbon fibers length has very important effect on the conductive network; wet pressing, wood fiber beating and wood fiber proportion affect the contact resistance greatly. By adjusting the carbon fibers length, wood fiber proportion and papermaking process, conductive network ...
The calculation of hydraulic conductivity by a modified Millington-Quirk method with a matching factor gave conductivity values closely approximating experimentally measured values. The technique requires knowledge of the moisture characteristic and the saturated conductivity. A number of factors that affect ...
aBoth models exogenous disturbance factors will affect the production units are also included among the endogenous technological invalid, the true measure of technical efficiency and the level of technical efficiency greatly deviate. 外生干扰因素将影响生产单位的两个模型在内在技术无效,技术效率真实的措施之...
Bio-receptive façade panels that support the natural growth of mosses, micro-organisms, and small plant species are potential alternatives than traditional green walls. Supporting the moss's development naturally could offer great potential for achieving ecologically richer, healthier, and zero-carbon ...
Effect of stem bending on hydraulic conductivity and wood strength of loblolly pine Stems of 30-year-old loblolly pine (Pinustaeda L.) trees were bent with a winch to determine the effect of bending, which might occur from severe wind stre... TS Fredericksen,RL Hedden,SA Williams - 《Cana...
the flow conductivity will decrease with the increasing of the fiber concentration,and fiber wrap proppant has the largest impact on the proppant conductivity;parameters that affect flow conductivity are listed in a descending order:closure pressure,the number of proppant slug,the fiber concentration,...
