Reflective Film Class I, Class IIAccording to the relevant standards, reflective films are classified as follows:
1. ** Class I reflective film (the corresponding type was not mentioned in the original national standard)**:
- Generally, it was a glass marble-type structure with embedded lenses, known as an engineering grade reflective film.
- The brightness characteristic was regulated by the relevant standards.
- The service life is usually seven years, and it can be used for permanent traffic signs and work area equipment.
- Compared with the original national standard Grade 4 film, there are some differences, such as the addition of orange and gray colors, and the change in reflective requirements.(The observation angle is changed from 0.2°, 0.33°, and 1° to 0.2°, 0.5°, and 1°. The reflective performance requirements are lowered in certain colors and angles. The purpose is to emphasize the micro-distance and large-angle properties of the reflective film.) It is clear that the service life is 7 years, and the maximum decay of the brightness (reverse transmission coefficient) in the aging resistance test is still 50% higher than the index value.
2. ** Class II reflective film (the corresponding type is not mentioned in the original national standard)**: There is no detailed independent description of Class II reflective film in the provided information.

What are Class I and Class II journals?The first type of journals were high-impact journals in the fields of literature, art, and social sciences. They usually had high academic value and reputation. These journals usually publish high-quality papers, research, and other academic resources that have a wide impact on academia and society.
The other type of journals were journals that published high-quality research papers and reports in the field of natural sciences. These journals usually focused on specific scientific fields such as physics, chemistry, biology, mathematics, etc. and published important research results in these fields.
It is worth noting that journals in different fields may have different requirements and standards, so different types of journals may be suitable for different research fields. At the same time, the division between one type of journal and another type of journal could also be controversial and different views could exist.
Identification standards for Class I and Class II solid wastesThe identification standards for Class I and Class II solid wastes were determined according to the Methods for Toxic Leaching of Solid Wastes (GB5086 -1997) and the Integrated Waste Water Discharging Standard (GB8978 -1996). According to these standards, a type of solid waste refers to the general industrial solid waste that does not exceed the maximum permitted discharge concentration of any kind of contamination in the extract obtained according to the extraction test, and the pH value is in the range of 6~9. The second type of solid waste referred to the general industrial solid waste with one or more kinds of contamination concentration exceeding the maximum allowed discharge concentration in the extract obtained according to the extraction test, or with a pH value outside the range of 6~9. These standards were mainly based on the toxicity, corrosiveness, flammability, environmental pollution risk and other characteristics of the waste to identify and distinguish.
The difference between class ii and class i in the examination and application of ShenzhenshiThe difference between Class I and Class II was mainly reflected in the position inspection and ability test.
In terms of job inspection, there was an urgent need for professional positions, grassroots first-line positions, and urban government positions. The comprehensive management of municipal and district organs, assistant judges, and assistant public prosecutor positions were tested for Class I, while the street, administrative law enforcement, and police positions were tested for Class II.
In terms of ability testing:
- Class I mainly tested the candidate's reading comprehension ability, comprehensive analysis ability, ability to raise and solve problems, and writing ability.
- Reading comprehension required a comprehensive grasp of the content of the given information, an accurate understanding of the meaning of the given information, an accurate extraction of the views contained in the facts, and the revelation of the essential problems reflected.
- The comprehensive analysis ability required one to analyze and summarize all or part of the content, opinions, or problems of the given information, think about the content of the information from multiple angles, and make reasonable deductions or evaluations.
- The ability to raise and solve problems requires the use of one's own knowledge, practical experience, or life experience. On the basis of understanding and analysis of the given information, one must discover and define the problem, make an evaluation or balance, and propose solutions or measures to solve the problem.
- The ability to express one's thoughts in words required one to be proficient in using the designated language, using explanations, statements, discussions, etc., to accurately, accurately, concisely, and smoothly express one's thoughts and opinions.
- Class II mainly tested the candidates 'reading comprehension ability, implementation ability, problem solving ability, and writing ability.
- Reading comprehension ability required one to be able to understand the main content of the given information, grasp the relationship between the various parts of the given information, and make appropriate explanations for the opinions and facts involved in the given information.
- The ability to carry out tasks requires one to be able to accurately understand the work objectives and organizational intentions, follow the principle of administration by law, and complete tasks in a timely and effective manner according to the objective and actual situation.
- The ability to solve problems required the use of one's own knowledge and experience, to make correct analysis and judgment on specific problems, and to propose practical measures or methods.
- The ability to express words requires proficiency in using the designated language to accurately and reasonably explain, state, or explain events and opinions.

World War II British A-class destroyerThe A-class destroyer was an experimental destroyer of the British Royal Navy. After the signing of the Washington Navy Convention, the Royal Navy dismantled more ships. In order to make up for its combat power, in 1923, the Ministry of the Navy invited various destroyer shipyards to design new destroyer. Yarrow Shipyard and Thorncroft Shipyard each won a design and construction contract, named Ambush and Amazon respectively.
Ambush (ship number D38) was built in December 1924, launched on January 15, 1926, and commissioned on April 9, 1927; Amazon (ship number D39) was built on January 29, 1925, launched on January 27, and commissioned on May 5, 1927.
It had 138 crew members, a standard displacement of 1192 tons, and a full-load displacement of 1585 tons. The size of the ship was 98.15m x 9.45m x 2.59m (Amazon was 95m x 9.6m x 2.9m). In terms of military equipment, there were four 120mm BTL Mk. I cannons (range 14400 meters, maximum firing rate 5 to 6 rounds per minute, 190 rounds), two Mk. II 2-pound anti-aircraft guns (100 rounds per gun), four Lewis anti-aircraft machine guns, and two triple-mounted 533mm caliber torpedoes. After the outbreak of World War II, it was modified. Two 120mm main guns and one triple torpedoes were removed, and one 76mm anti-aircraft gun, two 20mm Oerlikons, a rangefinder and radar shooting director, as well as a hedgehog anti-submarine rocket launcher and a heavy depth bomb launcher were added.
The power system was composed of three Yarrow type furnaces and two geared steam turbine. The main engine output power was 35500 horsepower for Ambush and 42000 horsepower for Amazon. It had two axes and twin propellers, and its endurance was 3400 nautical miles/15 knots. The maximum speed was 37 knots for Ambush and 38.7 knots for Amazon.
After the completion of the two ships, they joined the Royal Navy's Atlantic Fleet. From April to August 1928, they went to South America and the West Indies to test their performance in tropical areas. After the outbreak of World War II, Ambush joined the 16th Destroyer Division in Harwich. On June 10, 1940, Ambush carried out the evacuation of the 51st Infantry Division in Le Have.
