Introduction to Chinese Characters
Chinese characters, also known as Hanzi are one of the earliest forms of written language in the world, dating back approximately five thousand years. Nearly one-fourth of the world’s population still use Chinese characters today. As an art form, Chinese calligraphy remains an integral aspect of Chinese culture.To get more news about chinese alphabet a to z, you can visit shine news official website.
There are 47,035 Chinese characters in the Kangxi Dictionary , the standard national dictionary developed during the 18th and 19th centuries, but the precise quantity of Chinese characters is a mystery; numerous, rare variants have accumulated throughout history. Studies from China have shown that 90% of Chinese newspapers and magazines tend to use 3,500 basic characters.
Evolution of Chinese Characters
Chinese characters have evolved over several thousands of years to include many different styles, or scripts. The main forms are: Oracle Bone Inscriptions , Bronze Inscriptions, Small Seal Characters , Official Script , Regular Script , Cursive Writing or Grass Stroke Characters , and Freehand Cursive .
The presumed methods of forming characters was first classified by the Chinese linguist Xu Shen , whose etymological dictionary Shuowen Jiezi divides the script into six categories, or liushu : pictographic characters,, self-explanatory characters, associative compounds , pictophonetic characters , mutually explanatory characters , and phonetic loan characters . The first four categories refer to ways of composing Chinese characters; the last two categorizes ways of using characters.
It is a popular myth that Chinese writing is pictographic, or that each Chinese character represents a picture. Some Chinese characters evolved from pictures, many of which are the earliest characters found on oracle bones, but such pictographic characters comprise only a small proportion (about 4%) of characters. The vast majority are pictophonetic characters consisting of a “radical,” indicating the meaning and a phonetic component for the original sound, which may be different from modern pronunciation.

Best 3D Printer for 2023
Once the purview of dedicated hobbyists, 3D printing has become much more affordable and accessible, thanks to high-quality, low-cost printers and printing materials. Gone are the days of having to build complex machines from scratch and hoping that one print might succeed out of 10 attempts.Get more news about pa powder printing,you can vist our website!
3D printers are becoming faster and producing much better quality, so there's never been a better time to get started in the industry. Printers can be used for so many projects, from cosplay to small business ventures, that having at least one in your home just makes sense.
Which is the best 3D printer?
I've spent over a decade and countless hours testing 3D printers in as many ways as possible to bring you the best 3D printers in every class. Right now, the Bambu Lab P1P is our front-runner: It's fast, it can produce excellent detail and it's well priced.
This list includes both small and large 3D printers, with attention paid to print speed, the size of the build plate, the cost of PLA filament, the kind of print head included and other important details. And once you've decided to take the plunge into additive manufacturing -- that's what 3D printing essentially is -- there's also an FAQ below.
The P1P from Bambu Lab is the type of printer I wish I had owned when I first started out. The quality is excellent, up there in the top three of all the printers on this list, and the speed is staggering. It's so fast you can print three times faster than almost every other printer on this list.
No best 3D printer list is complete without the Prusa MK3S Plus. For nearly a decade, it has dominated the market and continues to be the go-to printer for anyone looking to make a business from 3D printing. It is fast, though not the fastest, and creates quality prints every time. I can count the number of print fails from MK3 on one hand, and I have had it for nearly seven years. If you have the $650, you should buy one of these.
I'd avoided Ender-3 printers for a long while because they came in kit form and required many hours of assembly, setup and fine-tuning to use. For just a little more than the kit versions, the newer Ender-3 S1 comes nearly fully preassembled and with high-end features like a direct drive extruder and a self-leveling bed.
Print quality even out-of-the-box was excellent, although a lot of that comes down to having good models to work from. I'd love it to have a touchscreen and Wi-Fi, but apart from those missing features, this is a great way to get polished results from a sub-$400 3D printer.
The AnkerMake M5 is a new breed of 3D printer. Its speed is unrivaled on this list and the quality of the end product is on par with anything I've seen. When you can get this quality level in a 3D print job in around half the time of its closest competitor, it's hard to recommend anything else for someone with the money to buy one.
The Difference Between Cold Drawn and Extruded Metals
Forming metals into specific shapes can be a challenging process. While metal bars and rods can be formed relatively simply, shapes such as tubes, beams, and various types of channel bar are metal configurations that sometimes require special forming processes to create. Two common metal forming processes used are extrusion and cold drawing. While both are common methods of shaping metal, there are differences between them that should be understood before making a metal purchasing decision.Get more news about Precision Cold Extrusion,you can vist our website!
What is Extrusion?
Extrusion is a metal forming process used to make complex shapes. It involves forcing a metal through one side of a die and having a finished product come out the other side. Extrusion is commonly done to form Aluminum. Extruding metal has several steps that are required.
A metal billet is shaped through smelting, solidifying, and rolling.
The billet is heated up to a temperature suitable for extruding. The heat makes the metal more malleable and easier to form.
Pressure is exerted on the billet against the die. The dies used in extrusion have been precision machined to ensure that a quality piece of extruded metal with acceptable dimensions comes out the other side of the die.
Once the metal is forced through the die, it can be cut to various lengths, coated, annealed, or have any other post-extrusion procedures applied to it.
What is Cold Drawing?
Like extrusion, cold drawing is also used to form complex shapes and requires a metal billet to already be formed prior to beginning the process. However, unlike extrusion, heating the billet is not part of the cold drawing process. Rather than being fed through one die, the metal is fed through a series of molds through the cold drawing process. This is because the metal is less malleable and formable without the addition of heat. The number of dies a billet goes through depends on the complexity and thickness of the final shape. After the billet has been cold drawn to the correct metal shape and size, it is ready for post-processing. Cold Drawing is commonly done to form steel and stainless steel, but can also be used to form aluminum.
Notable during the cold drawing process is that the metal being formed goes through plastic deformation. Care must be taken during the cold drawing process to ensure that excessive plastic deformation doesn't occur as it can result in tears in the metal or a brittle final product.

Stained-Glass Table Lamps
After first publishing this story, a Twitter user assured me that one of the lamps being sold on Twitter is indeed real, even if the product doesn't look quite like the photo being used to advertise it. But be careful out there. Some of them are definitely fake.Get more news about high quality custom glass table lamp,you can vist our website!
A series of stained-glass table lamps have sprung up on websites like Amazon, Twitter and Etsy recently, with people shelling out real money for the intricately created decorations. But there are countless reports that people have not received their lamps, and there's probably a very good reason for that. Many of these images of lamps were created using artificial intelligence tools. They're simply not real lamps.
"Transform any room in your home into a magical wonderland with the Stained Glass Table Lamp. It's time to find your inner oasis and immerse yourself in magic," one listing on Amazon reads.
The listing goes on to claim the glass in these lamps is "hand-cut" and everything is handmade. How much does something like this cost? Just $24-an absurdly low price for such an intricate lamp made of expensive materials and labor. In fact, some platforms have an even cheaper price, with these lamps selling for just $6.
But buyer beware. Because I emailed with the real creator behind some of these images and many of these lamps don't exist in the real world.
Vishma Maharaj, who goes by the name Whizical Mermaid on Etsy, sells this AI-assisted art. But Maharaj isn't selling any lamps. Maharaj used AI-image generator Midjourney to create the artistic concoctions and simply sells prints of the colorful lamps, something that buyers can actually purchase.
"What is being done on these various websites has been without my consent nor am I affiliated with any of them," Maharaj told me over email.
"I have tried reporting them to Facebook but have yet to receive a response. They are even being sold on Amazon & Ali Express in addition to the many ads that have been posted on Facebook. This has been very upsetting and stressful to say the least," Maharaj continued.

NEWARK LAUNCHES CONTAINERIZED TRASH BIN PROGRAM IN BUSINESS DISTRICT
Mayor Ras J. Baraka announced today that the City Department of Public Works began a containerized waste bin pilot program in the downtown business district. The program is part of the “Love Newark Keep it Clean” campaign efforts and aims to clear sidewalks of trash and debris, and improve aesthetics and quality of life. The city will supply business owners with these specially designed bins to safely and sanitarily hold trash for later collection. The pilot started on Broad Street between Lafayette and Bank Streets.Get more news about trash bin,you can vist our website!
“Newark’s downtown density of consumers and producers generates the volume of waste expected of any productive city,” said Mayor Baraka. “By providing aesthetically pleasing, rodent-proof sidewalk trash containers, we gain a safe, sanitary way to store garbage awaiting pickup, and simultaneously improve life for our business owners and residents alike.”
In the quest to provide a clean and enjoyable commercial experience to our city’s residents, shoppers, and visitors alike, we are proud to be instrumental in bringing a more progressive means of containing trash for pickup to Newark’s downtown area and eventually to other areas of the city as well,” said Department of Public Works Director Craig Smith.
This program to make sealed containers available to business owners is based on a similar program that was launched last year in New York City’s Times Square, using the same supplier, Citibin.
As part of Mayor Baraka’s “Love Newark Keep It Clean” campaign, designed to reduce littering and beautify Newark, the pilot program launched in the downtown area where local businesses often lack the resources to properly store trash for disposal.
