[0071] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three kinds of relationships. For example, the first component and / or the second component can represent: the first component exists alone, the first component and the second component exist at the same time, and the second component exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0072] It should be understood that, although the terms first, second, third, etc. may be used to describe certain components in the embodiments of the present application, these components should not be limited to these terms. These terms are only used to distinguish the components from each other. For example, without departing from the scope of the embodiments of the present application, the first so-and-so component may also be referred to as the second so-and-so component, and similarly, the second so-and-so component may also be referred to as the first so-and-so component.

[0073] Depending on the context, the words "if" and "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining" or "in response to monitoring." Similarly, depending on the context, the phrases "if it is determined" or "if monitoring (stated condition or event)" may be interpreted as "when determining" or "in response to determining" or "when monitoring (stated condition or event)" or "in response to monitoring (stated condition or event)."

[0074] In the embodiments of the present application, "substantially equal to", "substantially perpendicular to", "substantially symmetrical", etc. means that the macroscopic size or relative position relationship between the two features is very close to the relationship mentioned. However, those skilled in the art know that due to objective factors such as errors and tolerances, the position relationship of objects is difficult to be constrained exactly at a small scale or even at a microscopic angle. Therefore, even if there is a slight error in the size and position relationship between the two, it will not have a significant impact on the realization of the technical effect of the present application.

[0075] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such a product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.

[0076] In each of the above-mentioned embodiments, although the above-mentioned methods are illustrated and described as a series of actions for simplicity of explanation, a person skilled in the art should understand and appreciate that these methods are not limited by the order of the actions, because according to one or more embodiments, some actions may occur in a different order and / or concurrently with other actions from those illustrated and described herein or not illustrated and described herein but understandable to those skilled in the art.

[0077] It should also be noted that those skilled in the art can understand that in order to enable readers to better understand the present application, the embodiments of the present application provide many technical details. However, even without these technical details and various changes and modifications based on the above-mentioned embodiments, the technical solutions claimed for protection by the claims of the present application can be basically realized. Therefore, in practical applications, various changes can be made to the above-mentioned embodiments in form and detail without departing from the spirit and scope of the present application.

[0078] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
