There were many models of domestic RS232 chips to choose from, such as the TNT3232E of Siruipu, SIT3232Eose and RSS232 of Xinlite. These chips complied with the rs-232 standard, supported 3.3V and 5V power supply, had a dual receiver and transmitter, and the communication speed could reach 250Kbit/s. They are suitable for a variety of applications, including battery-powered devices, industrial human-machine interface, laptops, and printer. In addition, domestic chips could replace imported chips and achieve PIN-TO-Pin replacement. The performance parameters were basically the same. However, the information on whether the non-isolated domestic RS232 chip could reach 1 mps was not clear.

Some information about the domestic RS232. It was an interface standard for serial communication, which could connect two computers or other electronic devices. The domestically-made RS232 interface chip has good reliability and programming, and can meet various application requirements. Some domestic companies have launched a series of domestic RS232 products, such as DP3232, TD541S232H, and CH9102. These products have low power consumption, high data rates, and reliability. In addition, there were some domestic substitutes, such as MM32 and GD32. Although the pin definition was compatible with STM32, the underlying structure and register settings might be different. In general, domestic RS232 products were competitive in meeting communication needs and could help customers reduce overall design risks and procurement costs.

On the morning of November 6th, 2020, a certain institute held the first financial engineering quantitative investment training results exhibition in Building 9. The president, deputy secretary of the party committee, deputy president, doctor, quantitative investment training instructor, overseas returning students, and all members of the financial engineering level 17 participated. Students built investment models with the help of modern statistics and mathematical methods, implemented the models with computer technology and Python language, and optimized them into reused investment strategies. They implemented investment decisions with practical investment concepts, analyzed, judged and traded financial markets through quantitative analysis of qualitative risks, clearly demonstrating the process of quantitative investment. This exhibition affirmed the students 'ability to fully apply their professional knowledge, improve their enthusiasm and professional technical level, and strengthen the confidence of teachers and students in practical training. It had a major impact on the continuous and efficient development of the financial engineering major in the future.

A quantitative hedged product was an investment product. Its investment strategy was to buy a stock combination and short the stock index futures at the same time. As long as the stock combination could outperform the stock index futures, it could obtain positive returns. The purpose was to obtain returns that were completely independent of the market trend. Its income can be divided into two parts: one is the return of the stock relative to the market (excess return); the other is the return of the stock index futures relative to the market (hedge-cost). The difference between the two is the return of the hedge-fund. The quantitative hedges that traded domestically listed A-shares and stock index futures would seek basic returns that exceeded the market benchmark through the quantitative stock combination, and manage the market's systematic risks through stock index futures, striving to obtain absolute returns under various market conditions. However, the fluctuation of quantitative hedges was relatively large. For example, when the market showed an obvious one-sided trend recently, the fluctuation of quantitative hedges increased significantly. At the end of September, the sharp pull of the index and the extreme positive basis difference made the neutral strategy suffer from both sides, becoming the worst performing strategy in the third quarter, with an average return of-1.45%, and only 30% of the products obtained positive returns. In addition, there was a significant difference in the performance of public and private equity hedges. The average return on public offerings was 3.28%, while private offerings were 5.86%. This was mainly due to the restrictions on public offerings, high-frequency trading, and reverse trading. At the same time, there were significant differences in the performance of domestic and foreign hedges. The average performance of domestic hedges was 2.24% higher than overseas, mainly because domestic markets were dominated by retail transactions, so the effectiveness was relatively weak and the excess returns were relatively easy to do.

The quantitative calculation was a calculation method that used specific numbers and statistics to evaluate or achieve a certain goal. For example, in the AKR evaluation, the completion degree scale and weight of the key results were set, and the goal achievement degree was calculated according to the completion situation. In the quantitative score of retired soldiers 'service performance, the total score was calculated according to different items such as service years, military rank, meritorious service, commendation, and corresponding standards. In the evaluation of the effectiveness of the quantitative calculation compliance training system, from the level of knowledge (e.g. test scores, knowledge maintenance), change in behavior (e.g. decrease in non-compliance, improvement in performance), satisfaction survey (such as satisfaction rating, feedback problem statistics), business result analysis (For example, risk reduction calculation, return on investment), participation analysis (for example, attendance rate), etc., using numerical statistics to evaluate the training effect; in quantum chemistry calculation, using specific programs such as ORCA4.2 to calculate single-point energy, geometric optimization, etc.; In the intelligent driving simulation scene complexity quantitative calculation, the complexity of the complete simulation scene was determined and classified by analyzing and categorizing the elements of the simulation scene video, calculating the complexity of different types of scenes, and so on.

There were many options for the robotic trading software. TVCbot was a professional quantitative trading robot software that could automatically send TradingView strategies or indicators to multiple exchanges to place trades. CCR was another digital asset trading software that supported multiple trading strategies, multi-threaded operation, and intelligent tracking. GitHub also had the Win-Many Trading System. It was a stock quantitative robotic trading system that could realize multi-strategy automatic stock selection, automatic position control, automatic completion of trading and other functions. In addition, there were also fast-moving and quantitative DIY-based stock trading robots and other software, which were suitable for small and medium-sized investors and stock players. As for the virtual currency trading platform and the perpetual contract trading robot, the search results did not provide specific software names. Therefore, further investigation and research were needed on the specific choice of the robotic quantitative trading software.

The quantitative research methods could be roughly divided into the following categories: 1. The common quantitative research methods in economics and statistics used the demand and supply of the " supply and demand theory " as the cornerstone of research, and paid attention to the reasonable allocation and adjustment of resources. In art and design related majors, the object of quantitative research was usually the user's needs. There were roughly four directions: weight solution, demand classification, demand transformation, and program evaluation and optimization. However, the direction and use of quantitative research were not limited to these. 2. The specific research methods include the survey method, experiment method, content analysis method, social network analysis method, etc. Among them, the survey method was the most commonly used implementation method in quantitative research, including the design of the survey, sample, data statistics, writing reports, etc. The presentation method in the thesis generally had an independent research method part, and its logical structure was data description-data quality assessment-variable definition-analysis method. 3. Under the quantitative research, a variety of statistics and machine learning algorithms could be used for data analysis, such as narrative statistics, association analysis, regress analysis, and cluster analysis.

Here are some common ways to express the results: ** I. A quantitative expression for uncountable terms ** 1. ** Using a measure word phrase ** - As for the uncountable substance, such as a piece of paper, a glass of water, a bottle of wine, a kilogram of rice, a loaf of bread, a bar of chocolate, and so on. - In this way, a specific measure word was used to express a specific quantity. 2. ** Use adjectives or adverbs to express quantity ** - "much" is used to indicate many uncountable names, such as "There is much water in the river." There is a lot of water in the river." - "Little" means very little, as in "I have a little time." (I barely have time.)" - "A little" means a little, as in "I need a little help." I need some help." - "A lot of/lots of" means a lot, as in "There is a lot of traffic today." The traffic is very heavy today." 3. ** Other ways to express quantity ** - Use a container to express it, such as a cup of tea, a bowl of soup, a bag of rice, and so on. - Words of degree, such as a great deal of, a large amount of, words of scope, such as some, any, and adverbs of degree, such as very, quite, too, enough. ** 2. The quantitative expression of the relevant results of quantitative transactions in the financial field (taking the transaction volume as an example)** 1. It could be directly expressed in terms of a specific amount or number of transactions. For example, the original quantitative transaction might have a transaction volume of 100 billion or 150 billion a day, but after the handling fee was increased, it might only be half of the previous volume. For example, if the previous volume was 100 billion, it might now be around 50 billion. You could also use the handling fee for each transaction (such as increasing the handling fee to 1 yuan per transaction) and the number of transactions (such as less than 20,000 transactions per day) to measure the transaction situation. 2. By comparing the results, such as the volume of the quantitative trading and the volume of the short-term manual trading, the position and influence of the quantitative trading in the market could be expressed. ** 3. The result of a quantitative expression of an abstract concept such as "love"(an indirect quantitative expression)** 1. ** In terms of behavior ** - Observing the number and degree of care, care, support, sacrifice, etc. of one person for another. For example, calculating the number of times a person gave up their own interests for their partner, or the frequency of selfless help when the other party needed it, these behavior data could reflect the quantitative results of love to a certain extent. 2. ** In terms of emotional communication ** - It was measured from the frequency of verbal expression, the frequency of physical contact, the number of shared emotional experiences, and so on. For example, the number of intimate hugs per week and the length of communication per day were counted as part of the quantitative results of love. 3. ** Time investment ** - Calculating the amount of time a person is willing to invest in their loved ones. For example, the amount of time he spent with his partner every month, or the proportion of time he spent participating in the other party's life affairs. 4. ** Quality of life improvement ** - It was measured by the specific indicators of material and spiritual improvement, such as the specific amount of income increase after working together, the quantitative score of the improvement of the living environment (such as the number of square meters of living area increased, the comfort score of the living environment increased, etc.), and the quantitative improvement of cultural accomplishment (such as the increase in the number of books read, etc.). 5. ** In terms of subjective feelings ** - Although it was difficult to directly measure, there were some indirect methods, such as conducting a survey or interview on positive emotions such as happiness, satisfaction, and security. A certain rating standard (such as 1 - 10 points) was used to express the quantitative results of subjective feelings, thus reflecting the quantitative results of love. However, this method was only a reference because love was a complex and multi-dimensional emotional experience.
