QM has the following meanings:
1. QM (Quality manage): Quality management refers to determining the quality policy, goals and responsibilities, and through quality planning, control, Quality management and its implementation methods are introduced in mainstream business education such as EMBA and MBA to ensure and improve all activities to achieve its realization.
2. QM (Quantum Mechanics): Quantum Mechanics, quantum mechanics (Quantum Mechanics), is a theory of physics. It is a branch of physics that studies the movement laws of microscopic particles in the material world. It mainly studies atoms, molecules, and condensation. Basic theories of state matter, as well as the structure and properties of atomic nuclei and elementary particles.
Together with the theory of relativity, it forms the theoretical basis of modern physics. Quantum mechanics is not only one of the basic theories of modern physics, but also widely used in disciplines such as chemistry and many modern technologies.
3. QM: Gas coal, a coking coal with a shallow degree of coalification, can produce higher volatile matter and more tar when heated, and the thermal stability of the colloid is lower than that of fertilizer. Coal can be coked alone, but the coke is mostly slender and brittle, with more longitudinal cracks. Therefore, the crushing strength and wear resistance of coke are worse than other coking coals.
QM Quality Management Notes:
In the enterprise field, quality control activities are mainly the production site management within the enterprise. It has nothing to do with whether there is a contract. It refers to the purpose of achieving and maintaining quality. and carry out activities in terms of technical measures and management measures for control.
Quality inspection is subordinate to quality control and is an important activity of quality control. Internationally, quality control objects can set witness points or stopping points according to their importance and supervisory control requirements.
Witness points and stopping points are both quality control points. Due to their different importance or the degree of their quality consequences, their operating procedures and supervision requirements are also different.
