As used in the present application, terms “approximately”, “substantially”, “essentially”, and “about” are used for describing and explaining a small variation. When being used in combination with an event or circumstance, the terms may refer to an example in which the event or circumstance occurs precisely, and an example in which the event or circumstance occurs approximately. For example, when being used in combination with a value, the terms may refer to a variation range of less than or equal to ±10% of the value, for example, less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%. For example, if the difference between two numerical values is less than or equal to ±10% of the average of the values (e.g., less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%), the two values may be considered “about” the same.

In the present application, unless otherwise particularly indicated or limited, relativistic wordings such as “central”, “longitudinal”, “lateral”, “front”, “back”, “right”, “left”, “inner”, “outer”, “relatively low”, “relatively high”, “horizontal”, “vertical”, “higher than”, “lower than”, “above”, “below”, “top”, “bottom”, and their derived wordings (such as “horizontally”, “downward”, and “upward”) should be construed as referenced directions described in the description or shown in the appended drawings. These relativistic wordings are merely used for ease of description, and do not require constructing or operating the present application in a specific direction.

Further, to facilitate description, “first”, “second”, “third”, “fourth”, and the like may be used in the present application to distinguish among different components in a diagram or a series of diagrams. The wordings “first”, “second”, “third”, “fourth”, and the like are not intended to describe corresponding components.

In the present application, unless particularly specified or defined, “dispose,” “connect,” “set,” “fix,” and similar wordings are widely used, and a person skilled in the art can understand, according to specific situations, that the above-described wordings may indicate, for example, a fixed connection, a detachable connection, or an integrated connection, alternatively, the wordings may indicate a mechanical connection or an electrical connection, and alternatively, the wordings may also indicate a direct link or an indirect link through an intermediary structure.

In addition, sometimes, a quantity, a ratio, and another value are presented in a range format in the present application. It should be appreciated that such range formats are for convenience and conciseness, and should be flexibly understood as including not only values explicitly specified to range constraints, but also all individual values or sub-ranges within the ranges, like explicitly specifying each value and each sub-range.

References throughout the specification to “some embodiments,” “partial embodiments,” “one embodiment,” “another example,” “example,” “specific example” or “partial examples” mean that at least one embodiment or example of the application comprises specific features, structures, materials or characteristics described in the embodiments or examples. Thus, the descriptions appearing throughout the specification, such as “in some embodiments,” “in an embodiment,” “in one embodiment,” “in another example,” “in an example,” “in a particular example” or “for example,” are not necessarily the same embodiment or example in the application. Furthermore, the specific features, structures, materials or characteristics in the descriptions can be combined in any suitable manner in one or more embodiments or examples.

Although the illustrative embodiments have been shown and described, it should be understood by those skilled in the art that the above embodiments cannot be interpreted as limitations to the present application, and the embodiments can be changed, substituted and modified without departing from the spirit, principle and scope of the present application.
