The journey to Mars faced many unique challenges and situations. In terms of radiation, during the 360-day trip to Mars, the radiation dose received by astronauts was close to the warning value set by NASA, which did not include the dose during their stay on Mars. Radiation in space, especially cosmic rays composed of high-energy charged particles, was extremely harmful to the human body. It could break DNA and increase the risk of cancer. On the way from Earth to Mars, without the protection of the magnetic field, astronauts were exposed to fatal radiation. Although the spacecraft's outer shell could block some of the radiation, the radiation dose would be even greater when walking on the surface of Mars. If the protective barrier was added to reduce radiation, it would increase the burden on the spacecraft, because every additional kilogram of weight on the spacecraft would increase the launch cost by millions of dollars. Therefore, by making the spacecraft fly faster, the journey time could be shortened, or the astronauts 'own anti-radiation ability could be improved. For example, astronauts with specific genetic mutations supplemented with folate, astronauts with iron metabolism problems bled before flying and restricted iron intake in space. In terms of kidney health, the latest research shows that the human body may not be able to withstand the trip to Mars. Long-term space life would change the structure and function of the kidneys, and cosmic radiation would cause permanent damage to the kidneys. According to Musk's Mars landing plan, a one-way trip would take at least 270 days. The available research data showed that under high radiation and microgravity in space, the kidney tubulae responsible for regulating the balance of calcium began to shrink in less than a month. Astronauts often had kidney stones and other problems after performing space missions. The amount of radiation that humans received on the surface of Mars for a year was equivalent to the amount of radiation they received at the Hiroshima atomic bomb site. In addition, from a historical point of view, there had been a secret Mars project between the United States and the Soviet Union, where they had spent a huge sum of money to build the spaceship " Mary." However, due to the global economic crisis, the financial difficulties of the two countries forced the project to be suspended, and the spacecraft was sealed in a secret orbit under the nuclear ruins. Now, the trip to Mars had more business considerations. For example, SpaceX's early deployment of the Mars project could not only consolidate its leading position in the aerospace field, but also open up new business paths, attract top tycoons to invest, and open a new chapter in human exploration. The novel " Mars of Paradise " is equally exciting. Everyone is welcome to read it!

If it took more than ten seconds to search the novel page, it could be solved from the following aspects: ##1. From the perspective of a sql query 1. * * Tune the sql statement ** - * * Index optimization ** - Check if the columns involved in the query have a suitable index. For example, if the query is often filtered or sorted based on a column (such as the novel's category column, author column, etc.), and the column is not index, it may cause a full table scan and slow down the query. You can create an index for these columns that are often used for query conditions to improve query efficiency. - * * Avoiding complicated operations ** - Reduce the use of complex functions and sub-queries. If complex functions are used in the query (such as performing complex date function operations on the date column in the sql statement, such as extracting the year and comparing it), it may cause the database to not be able to effectively use the index. Try to convert complex logic into simple query conditions, such as comparing dates using a function to directly compare date ranges. - * * Limit the amount of data ** - If you don't need to get all the data during the query, you can use the Limit clause to limit the amount of data returned. For example, he could only display the most recently updated novels or the most popular novels, instead of searching for information about all the novels at once. 2. * * Monitor and analyze slow query ** - * * Turn on the slow query log (if you are using the Mystical database)** - You can set to enable the slow query log. For example, you can use the command `Sets Global slow_query_log ='ON';` Activate the slow query log,`Sets Global slow_query_log_file ='/path/to/slow_query.log';` specify the log storage path,`Sets Global long_query_time = 2;`(You can adjust the threshold according to the actual situation. For example, if the query takes 10 seconds, it is already very long. You can set the threshold to 5 seconds or lower). Record the query that takes more than the threshold. - * * Analyzing the slow query log ** - Use the `mysqldumpslow` tool to analyze the logs, such as `mysqldumpslow-sc-t10/path/to/slow_query.log`(The first 10 slowest queries are displayed in order of their number of occurrences). You can also manually analyze the query execution time, lock time, number of rows scanned, and executed sql statements contained in each record in the slow query log to find out the specific reason for the slow query. ##2. From the System architecture perspective 1. * * Caching Technology ** - It used a buffer technique to buffer the frequently queried data. For example, for the basic information of popular novels (such as title, author, introduction, etc.), if these data rarely changed, they could be stored in memory. When a user performs a query, the user first obtains the data from the buffer. If there is any data in the buffer, it will be returned directly to reduce the number of queries to the database. 2. * * content distribution technology (if multi-regional access is involved)** - If the novel website was visited by users from different regions, it would use content distribution technology (CDA) to distribute the website content to the CDA nodes in various regions of the country. Through the intelligent Domain Name System, visitors could connect to the CDA node with the fastest response speed, solving the network delay and congestion problems caused by cross-regional and cross-operator. This could improve the overall response speed, especially for content such as images and static pages. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
