Hand-painted landscape flowers
In order to draw a landscape flower painting, one first needed to do some preparatory work before drawing. The pen can be selected from the more commonly used gel pen, conference pen, signature pen, syringe pen, fountain pen, etc., according to their own habits; the paper is generally ordinary copy paper. As lines were the foundation of painting, if you were not confident, you could practice lines first. When practicing, you should pay attention to the continuity of the lines. You must be steady and sure when writing, and avoid hesitation, hesitation, and repetition of expressing a line. The lines had to have a basic pattern, such as being parallel to the side lines and perspective lines, or being vertical to the screen. Every time you practice, you need to maintain the continuity of the line practice. It is appropriate to practice five or six minutes a day. For the drawing of flowers, one had to understand the shape and characteristics of the flowers, such as the shape of the flowers, the distribution of branches and leaves, etc. Pay attention to the density of the flowers. The bright side (the light receiving side) can be summarized with simple lines, and the dark side (the back light side) can be denser. At the same time, he had to grasp the law of proximity, distance, and density to show the primary and secondary reality of flowers. The material for painting came from life, so he could observe the growth of flowers more often to get more inspiration. He could also combine the flowers with the surrounding trees, shrubs, flowers, and plants to form a combination of landscape vegetation. He had to pay attention to the height of the combination. During the drawing process, the brush must be fast, precise, and accurate. The lines must have a sense of ability and tenacity, and the brush must not hesitate. The novel "Mixed Flowers" is equally exciting. Everyone is welcome to click and read it!
What is the reaction phenomenon of starch and iodination turning blue?
Iodizing starch to blue was a chemical reaction. From the reaction principle, the starch was a spiral structure formed by the condensation of alpha-glucose molecules. Each glucose unit had a hydrogen group exposed outside the spiral. Iodine molecules interacted with these hydrogen groups and were embedded in the axis of the starch spiral. This effect was called clathration. The product was a clathration. During this process, the properties of the hydrogen group changed, so it was a chemical reaction. This color reaction was very sensitive and could be used to identify the quantitative and qualitative analysis of starch. It could also be used to analyze the content of iodines. In the textile industry, it could also measure the completeness of cloth desizing. Different types of starch reacted differently with the iodines. Amylose was blue when it met the iodines, while starch was purple-red when it met the iodines. Dexterin was blue-purple, purple, orange and other colors when it met the iodines. Moreover, the clathrate formed by starch and iodines was the most stable at room temperature at a pH4, and the color reaction was most obvious in slightly acidic solutions. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

php import from txt file into the database
The following is a common way to import a txtfile into a database using Python: First of all, if the amount of data is large, you can consider using MysQL temporary tables to process it. You can use the OUT_END_END_END command to import data at high speed, but if the data file's code is different from character_set_database, you may need to import it line by line. It's best to have a user interaction page to manually confirm the order of import before import. For example, if you want to import a relatively simple file like serial_number.txt., you can follow these steps: 1. Establishing database connection: - In Python, you can use codes like `$conn = mysql_connect('127.0.0.1',' root',');`(This is the older mysql connection method. In practice, it may need to be adjusted according to the database extension used, such as mysqli or PDO) to establish a connection to the database. If the connection fails, you can use `die("Failed query: ". myssql_error();`to handle errors. - Choose the database you want to operate on, such as `mysoul_select_db',$conn) ordie("Failed query: ". mysql_error());`。 2. Read the txt-file contents: - Use `$content = file_get_contents("serial_number.txt');` to read the contents of the file. - To process the content, such as splitting it with a specific symbol, for example,`$contents = explode(",",$content);`(Assuming it is separated by commas). 3. Traverse the data and insert it into the database: - Loop through the split array, such as `foreach($contents as $k=> $v)`. - Construct and execute the SQL statement inserted into the database in the loop, for example,`mysql-query ("insert into serial_number (`id`,`serial_number`) Values','$id','$v')");`(Suppose you insert into a table named serial_number, and there are two fields, id and serial_number). In addition, you can write a more general function to handle the import of different structure of the TMT file into the database, like the following: ```php function loadTxtDataIntoDatabase($splitChar,$file,$table,$conn,$fields = array(),$insertType='INSERT'){ if(empty($fields)) $head = "{$insertType} INTO `{$table}` VALUES('"; else $head = "{$insertType} INTO `{$table}`(`".implode('`,`',$fields). "`) VALUES('"; $end = "')"; $sqldata = trim(file_get_contents($file)); if(preg_replace('/\s*/i','',$splitChar) == ''){ $splitChar = '/(\w+)(\s+)/i'; $replace = "$1','"; $specialFunc = 'preg_replace'; }else{ $splitChar = $splitChar; $replace = "','"; $specialFunc = 'str_replace'; } //The order of the data body cannot be changed, otherwise, there will be an error in the space or Tab separation. $sqldata = preg_replace('/(\s*)(\n+)(\s*)/i','\'),(\'',$sqldata); $sqldata = $specialFunc($splitChar,$replace,$sqldata); $query = $head.$ sqldata.$ end; if(mysql_query($query,$conn)) return array(true); else{ return array(false,mysql_error($conn),mysql_errno($conn)); } } ``` You can call this function according to the actual situation and pass in the corresponding parameters, such as the terminator, file name, table name, database connection, field name array, etc., to import the txt-file into the database. It should be noted that when processing file upload and import into the database, you should consider the options related to uploading files in the Python configuration file, such as file_uploads (setting whether to accept the upload of the file), memory_limit (setting the maximum amount of memory that can be allocated by the script), upload_max_size (limiting the maximum size of the uploaded file), post_max_size (limiting the maximum size of the information that can be accepted through the post method), and other reasonable settings to prevent problems during the import process. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

What's your reaction to being bitten by your dog?
The reaction after being bitten by a dog at home depended on the severity of the wound and whether the dog was sick. If the bite was relatively light, with only a slight bite mark, and the dog had been timely injected with rabies vaccine, there would be pain in the wound after the bite, and there would be no other abnormalities. If the bite was serious and the area was large, the wound would be in obvious pain after the bite, accompanied by redness and swelling. If the wound was serious, it might even cause fever. After being bitten by a dog with rabies, the incubation period after infection with rabies virus was short. About 1 - 2 weeks later, there would be symptoms such as ant-like feeling, fever, muscle soreness, etc. The disease would develop further, and there would be nervous system symptoms such as fear of water, sound, light, etc. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
