Two Different Types of Proyectors

Introduction of task analysis proposed by me The task is to evaluate the differences between the two different technologies we chose and evaluate the adaptability to the task from a physics perspective. . Applicability in home theater We chose two kinds of projectors, DLP projector (abbreviation of digital light processing) and LCD projector (liquid crystal display) to solve this problem.

The most important concept to understand in React.js is the component. The React component is one of two types. It is a function component or a class component. Terms representing two types, such as stateless and stateful, may be different. Functional components are also usually associated with the concept of presentation. In this article we refer to them as function components and class components. There is a big difference between State object and Props object. Within a class component, you can modify the State object, but the Props object represents a fixed value. Class components can change only their internal state, and their properties can not be changed. This is the central idea understood by React.

Different kinds of substances can be distinguished by two components, composition and characteristics. Material composition is the various components of a substance and their relative proportions. Material attributes are mass / attributes that distinguish matter samples from other substances. These attributes are usually divided into two categories: physical or chemical. You can observe or measure the physical properties without changing the composition of the substance. Physical properties are used to observe and describe substances. The physical properties of materials and systems are often described as precise and extensive. This classification is related to attribute dependencies on the size or scope of the system or object in question.

There are two types of material change: physical change and chemical change. As its name implies, physical changes affect the physical properties of substances and chemical changes affect the chemical nature of the substance. Many physical changes are reversible (heating and cooling, etc.), but chemical changes are usually irreversible or reversible only if additional chemical changes are possible. Another way of thinking is that substances are not fundamentally different substances due to physical changes, but substances may become chemically new substances due to chemical changes. For example, a mixed smoothie has two physical changes. The change in shape of each fruit and the mixture of various fruits. There is no chemical change in the smoothie ingredients during mixing (eg, there is no change in fruit moisture and vitamins), so it is known that no chemical changes occur.
