24 Ω ω Omega o ` MIGA the Greek alphabet is used in Greek, and it is also widely used in mathematics, physics, biology, chemistry, astronomy and other disciplines. The Greek alphabet is similar to the English alphabet and the Russian alphabet, except that the symbols are different and the nature of the phonetics is the same

The Greek alphabet is the first alphabet with vowels in the world. The Cyrillic alphabet and the Georgian alphabet used in Russian and Ukrainian are all developed from the Greek alphabet. People who have studied Russian will feel familiar when they use the Greek alphabet. The Greek alphabet has entered the vocabulary of many languages. For example, Delta, the international vocabulary, comes from the Greek alphabet Δ， because Δ It's a triangle

extended materials :

the Greek alphabet originated from the Phoenician alphabet, the Phoenician alphabet only has consonants, written from right to left, the Greek language developed vowels, the Greeks added vowels. Because the writing tool of the Greeks was a waxboard, sometimes the first line was written from right to left, and then it was written from left to right, which became the so-called "cultivated land" writing style. Later, it graally evolved into all writing from left to right. The direction of the letters is also reversed

the Greek alphabet was introced by the Romans and changed to Latin alphabet slightly, which became popular all over the world. Greek letters are widely used in academic fields, such as mathematics. The Cyrillic alphabet also evolved from the Greek alphabet

the English word alphabet comes from the popular Latin alphabet, which in turn comes from Greek αλφαβητον ( Beton is the first two Greek letters α Alpha) and β Beta)

in ancient Greek, extended symbols were often added at the top or bottom of the letters, such as: acute note, accent, raised and suppressed sign, wave sign, diaeresis, bold and soft Qi sign, etc α There are 26 different ways of writing

(1) acute note: the sound of the letter should be hard and flat

② accent: the pronunciation of the letter should be forced, and the sound should be gone

(3) raising and restraining sign: the pronunciation of the letter should be forceful, and the sound should be up. Boogie: indicates the [H] before the ancient Greek vowel. Consonant letter ρ At the beginning of a word, it always carries the bold Qi

(4) soft Qi sign: indicates that it does not exist [H]. Two ρ Although always in the middle of the word, initially written as the first ρ With soft Qi and the second with thick Qi; It's all omitted in Greek

⑤ ι Subscript: placed in letters α、η and ω It's a long vowel αι、ηι And ωι Sometimes written as a small letter of normal size adjacent to a capital letter

(6) diaeresis: placed on the letter ι and υ Used to indicate that the vowel is pronounced separately from the vowel in front of it

the umlaut is written above the lower case letters and above the left of the upper case letters. In the case of diphthong or diphthong, the second vowel receives a diacritical sign. The breath sign is written to the left of an acute or an accent, but below the circumflex. The accent is written above the diaeresis, and the acute or accent can also be written between two dots

in modern Greek, all the stress symbols are unified into a substitute sign, that is, the acute note, and the breath symbol is abandoned, but the diaeresis is still retained. Of course, if the Greek alphabet is used as a specific code, there is no need to add additional symbols

2. γ Radiation is usually accompanied by other forms of radiation, such as α Rays, β Rays. When a nucleus occurs α Decay or β During decay, the new nuclei are sometimes in the excited state. At this time, the new nuclei will transition to the lower energy level and release at the same time γ Particles. This is it. γ Radiation.

α 、β It's two Greek letters. Generally, it's a letter for angles, just like we use X and y for unknowns, and use X and y for angles α 、β express. such as α = 30 degrees β= 60 degrees, for example α=β And so on

alpha, i.e α， It is the first letter of the Greek alphabet. It has the meaning of the first, the beginning and the beginning. In alphabetic interpretation, alpha is the letter A. Used in all kinds of science and engineering disciplines

Β It's the Greek alphabet β， Beta (capital) Β， a lowercase letter β， It's the second Greek letter. In ancient Greek, beta means [b], but in modern Greek it means [v]. Modern Greek takes & quot; μπ& quot; It stands for [b]

extended data

lowercase α It is used to express in Physics:

1, angular acceleration

2, alpha particle and related alpha decay

3, the first Greek letter in Christianity α It stands for "start", the last letter in Greece Ω It stands for "end", especially God creates all things with beginning and end

It is also useful in modern European culture α It stands for "leader", excellent (person), and Ω To be led is to be led. It's like using a and Z to represent the first and last place, respectively

This symbol can also be used to replace the name of angle. For example: ∠ α

attached α It is similar to a, but it is not the same character, and the name used to represent the angle also has β，γ Etc

7. 1、 Proceres required for settled paternity test: settled paternity test is a process of proof provided by the owner himself, so the identification certificate only needs to be provided by the identification Party:
1. The proof that can prove the identity of the identified person: such as ID card, household register, military identity certificate, birth certificate, etc. Those without the above certificates need to apply for identification certificates from people's governments at or above the township level, street offices and police stations
2. The identified person must go to the forensic center to collect blood for identification, and complete the identification work. It is mainly used to verify identity, keep fingerprints and take photos
2. Samples required for settled paternity test: 2-4 ml of venous blood is usually drawn by the staff of the identification center for settled paternity test. Therefore, if the identified person who participated in settled paternity test has transfused other people's blood within half a year or has undergone bone marrow transplantation within two years, the identification result can not be obtained, And need to be identified to avoid the above time to participate in the identification!

9. CNC needs the program code after programming, GM code, CAD drawing does not know, it only knows the program, such as G00 G01. CAM software can be used to program and download to CNC. I suggest you read some basic NC books
this requires a third-party programming software, that is, open the programming software, import the CAD document into it (insert the CAD document, generally in the format of * DXF file), and then set the tool direction - --- select the tool - --- descent depth - --- select the graph to generate the tool path and output the program.
