Can a focusing lens be used as a telescope?
The working principle of the focusing lens was similar to some components of the telescope, but the functions of the two were not exactly the same. The focusing lens could not be simply used as a telescope. Focus lenses are often used to focus light onto a point or area. They are commonly used in cameras and other devices. Their main purpose is to achieve a focusing function to obtain a clear image. A telescope was an optical instrument specially used to observe distant objects. Through a series of optical components, it could magnify and observe distant targets.

Elasticanime js
In the reference, there is a jquery implementation with a rebound animation effect to return to the top of the plug-in involved in elastic animation related content, the key code is as follows:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>jQueryBack to top Plug-in elastic animation</title>
<link rel="stylesheet" href="css/font - awesome.min.css">
<link rel="stylesheet" href="css/demo.css">
<link rel="stylesheet" href="css/scrollTop_iconStyle.css">
<link rel="stylesheet" href="css/scrollTop_bgStyle.css">
</head>
<body>
<!-- Start Sections -->
<section class="scrollTop_section"><h1>Section1</h1></section>
<section class="scrollTop_section"><h1>Section2</h1></section>
<section class="scrollTop_section"><h1>Section3</h1></section>
<section class="scrollTop_section"><h1>Section4</h1></section>
<section class="scrollTop_section"><h1>Section5</h1></section>
<section class="scrollTop_section"><h1>Section6</h1></section>
<!-- End Sections -->
<!-- Start Div Scroll -->
<div class="scrollTop_top">
<i class="fa fa - angle - double - up fa - 4x"></i>
</div>
<!-- End Div Scroll -->
<script src="js/jquery - 1.12.1.min.js"></script>
<script src="js/scrollTop_script.js"></script>
</body>
</html>
However, this part of the code alone is difficult to fully explain all the relevant knowledge of the elastic animation JS. This is just a simple example to show the code structure of the elastic animation effect of the return to the top plug-in under jquery. In actual development, the implementation of the elastic animation may also involve more JS-related knowledge, including the animation time function, slow effect, object property operation and other complex knowledge systems.

How to double the compensation for the dismissal of contract workers in government agencies
If the government agency, as an employer, terminated the labor relationship with the contract worker without any legal reason and did not pay economic compensation, and the contract worker did not exist in the circumstances stipulated in article 39 of the Labor Contract Law, it could be determined that the employer's behavior belonged to the illegal termination of the labor contract stipulated in article 87 of the Labor Contract Law, and compensation should be paid, that is, to pay two months of his salary for every year of work, commonly known as 2N. For example, after working for three years, the average salary for the first 12 months was 5000 yuan, so the compensation should be 3×2×5000 = 30000 yuan.
