Weathered deposit A deposit formed by the accumulation of certain stable useful components in situ or in situ during the weathering process of the crustal surface rocks (including ore-bearing parent rocks and primary deposits), known as weathered deposits. According to the type of weathering, weathering materials, accumulation sites and methods, it is roughly divided into residual sand deposits, slope sand deposits, residual deposits and leaching deposits. Deposited deposit Under the action of external forces, the deposits, which are mainly composed of useful components by sedimentary differentiation, are called sedimentary deposits. Such deposits are consistent with the formation conditions and processes of sedimentary rocks, and therefore have the same general characteristics as sedimentary rocks, such as bedding, some contain fossils, relatively stable horizons, sometimes large scales, and easy to find and explore. According to its formation, it can be divided into mechanical sedimentary deposits, chemical and biochemical sedimentary deposits, and combustible organic rock deposits. 3. Combustible organic rock deposit This is a type of mineral deposit that can be used as a fuel source, including coal , oil , natural gas , and oil shale . Energy refers to a substance that can produce energy, or a resource that can be converted into various energy sources such as mechanical energy, thermal energy, electromagnetic energy, and chemical energy. Therefore, this type of deposit plays a very important role in national economy and people's livelihood and in international strategic resources. Of course, the use of coal and oil is not limited to energy use, especially oil, which is almost related to all industries. Combustible organic rock minerals account for more than 3/4 of the world's total mineral raw material production or total output value. This shows that this type of deposit has a special significance.
According to the temperature change of the
working environment, the thermostat will have some physical deformations within
the switch, resulting in some special effect. The thermostat will cause a
series of automatic control element of turning off and turning on, which is
also called temperature control switch, temperature controller, temperature protector,
referred to the thermostat. Through thermal protector, the temperature
protector will send the temperature to the thermostat and the thermostat will
send the commands to control the operation of the device in order to achieve
the desired temperature and the energy saving effect. Now the thermostat are
widely used in thermostat application appliances, motors, cooling, heating and
many other products.
The working principle of the thermostat is
automatically sampling, real-time monitoring through the temperature sensor.
The control circuit starts when the ambient temperature is higher than the
control set point. If the temperature still rise, when the temperature rose to
over-limit alarm set point, the thermostat start limit alarm function. When
temperature control can not be effectively controlled in order to prevent
destruction of the device also can be stopped by the trip device features
continue to run.
According to the function of the working,the thermostat have different types:Intelligent Thermostat,Remote Controlled Thermostat,Programmable Thermostat,Wireless Room Thermostat.

Definition and classification of exogenous deposits
A deposit formed by the aggregation of useful or useful components under the action of external forces, called an exogenous deposit. According to the different mineralization processes, it can be divided into two categories: weathered deposits and sedimentary deposits. Another type is a combustible organic rock deposit formed by biological accumulation. From a general perspective, it belongs to the category of sedimentary deposits. However, due to its particularity and complexity, it is generally studied as a special metallogenic theory.
