On the other hand, the surge in yields makes interest rates look more attractive than in developed economies, a situation that has been rare since late 2010: Awarded a UK patent, Senior’s PURe® range of energy-efficient aluminium windows and doors is the first on the UK market to benefit from an enhanced thermal barrier manufactured from expanded polyurethane foam (PUR). Traditionally used in cladding and insulation products, the innovative use of PUR as a thermal barrier in windows and doors gives the PURe ® range the potential to achieve U-values as low as 0.71W/m2 K when calculated as a commercial CEN standard window and 0.93W/m2 K when calculated as a CEN standard door. The "property right of the new system" is the premise. In November 2017, Advisor Perspectives published an article said that in addition to the improvement of fuel efficiency, petrol consumption decline is due in large part to the following factors: the ageing staff away from the workplace; The home office model is developing more and more; Social media takes the place of face-to-face communication, and travel is unnecessary. More and more young people are no longer driving their cars. And urban population growth accelerated, reducing per capita gasoline dependence. All things in the world are constantly moving. In all attributes of matter, motion is the most basic attribute, and other attributes are specific manifestations of motion attributes. For example, spatial attribute is the broad embodiment of physical activity. Time attribute is the persistence of material movement. Material movement form is varied, for each specific material movement form the corresponding form of energy, such as: and macro mechanical movement of the object corresponding to the form of energy is kinetic energy; The energy form corresponding to the molecular motion is heat energy; The energy form corresponding to the atomic motion is chemical energy; The energy form corresponding to the directional motion of charged particles is electric energy; The energy form corresponding to the photon motion is light energy; And so on. The motion characteristics of two objects can be described and compared by some physical quantity or chemical quantity. For example, two objects that make mechanical motions can be described and compared by physical quantities such as speed, acceleration and momentum. The current can be described and compared with current strength, voltage, power and so on. , but when the movement form phase at the same time, not two material movement characteristics only can describe and compare each other quantities is energy, the energy feature is moving all the common characteristics of material, energy scale is measure all movement in the form of a general. Thus, a new philosophical definition of energy can be made. 1. Industrial age
