(1) These eyes are so bright that they really look like two little light bulbs in the dark.
(2) The stars are like little electric lights that twinkle in the sky.
(3) Electric lights bring light to a dark room.
(4) After thinking for a long time
The light flashed
Zhang Jue suddenly understood
and proposed a solution to the issue.
(5) Customer needs must be created. Before the invention of electric light, no one had this need.
(6) When my father was in primary school, there was no electric light at home, so he had to study under a dim kerosene lamp.
(7) The light suddenly went out lishixinzhi/5753546 and the classroom was dark.
(8) “Not being able to bear” is also the premise of our creation and invention, from Edison's electric light to high technologycurrent like the Internet and cell phones, all of this is caused by. "not being able to bear" some backward phenomena appeared. If we “put up with” everything, we can imagine how slow technological progress will be.
(9) He can only “repair bicycles, install electric lights, mend pots, and make furniture... He uses vulgar standards of social benefits to measure differences among students and workers. He even blasphemed the literary masterpieces she admired... In short, her spiritual world is a "barren land"
(10) It is said that when two men and a woman walk in the street, all three of them will feel like light bulbs.
(11) People are so accustomed to electric lights, radios, televisions and telephones that it is difficult to imagine what life would be like without them
( 12) Seeing the spies arrive
It is dEvenu anxious
He turned off the light
Chaos in the theater
He took advantage of it to escape
(13) That means failure? Edison invented it. The electric light failed thousands of times, but he finally succeeded because he summarized the lessons and accumulated the experience thousands of times. was discouraged, I don't know how many years it would take for humans to see these bright street lights. You fail less than him
(14) Guan Ping, isn't this the light switch. the door usually works?
(15) Edison went there. After repeated research, we finally invented electric light
(16) If we are together, we must have a light bulb. . If you follow the light bulb, I can find my desk lamp.
(17) Ai Yin is definitely not smarter than me.
< p> (18) Compared to electric light, the first seems weak.(19) These few lightslarge and bright are suspended in the night sky, as if they are guards in the sky patrolling. electric lights like those on earth
(20) What surprises us even more is that almost all houses are equipped with wind or sun. It can produce electricity. At night, the lights are on, the television is blaring, and people are laughing and singing. Who would have thought that there would be such a place in the vast sand sea?
(21) I can operate in a dilapidated temple with an expressionless 20 foot tall statue of a god standing behind me... just as I would with running water, electric lights and other modern equipment. The work and life of the past tempted me, but for my ideal, let those days disappear forever.
(22) There is Watt under your pointer, Newton in your cold eyes and Edison in your ridicule. Don't rush them. You don't need to waitndre to ride on a steamboat, turn on an electric light or learn arithmetic to recognize them as your primary school students. Tao Xingzhi?
(23) There is Watt under your pointer, Newton in your cold eyes, and Edison in your hungry smile. Don't rush them. Do you have to wait until they get on a steamboat, turn on an electric lamp, and learn arithmetic before you recognize them as your elementary school students?
(24) On the second day of February, the dragon raises its head and has its hair cut. It is recommended to shave your head. The bald head can be used as a light bulb at night and. as a mirror during the day, it can also save shampoo, is economical and environmentally friendly. I wish you peace and happiness!
(25) When I entered the classroom of my class, I saw, among other things, the neat rows of desks, the white tiles, the bright lights and theclean floor. You will have a nice feeling. , a feeling of space and brightness.
(26) After his death, one night after his funeral, the American people dimmed the lights to show their respect for Thomas. Edison's invention of electric light triggered the world's sorrow.
(27) You think that as long as you work more seriously and more skillfully, you can avoid chaos, but one day, when you replace a light bulb in the yard that has a lifespan of five years , you suddenly realize that if you change it ten more times, your lifespan will end.
(28) Failure is the mother of success. Without failure, where would success be? If Nobel hadn't experienced thousands of failures, how could he have developed dynamite? of a breakdown, how can we invent electric light?
(29) Today the wire suddenly shorted, so my father volunteered to repair it. After a fewues minutes, the wire was repaired and the light. lit.
(30) The date when the hydroelectric plant will officially start producing electricity is fast approaching.
In a few days, we will be able to use electric lighting.< /p>
p>Let's see television!
Can be popularized,
1. Due to the good physical properties of optical fiber, the development and industrial application of professional optical fiber is growing. At the same time, it can also prevent data packets caused by network loss, advertising display, ships, etc., the ability to transmit images consumes valuable network resources;
2. only reduces the possibility of data conflicts, but also ensures the reliability of data transmission. Unmanaged transceiver, a pair of optical fibers as thin as spider silkWe can make 10 billion callss at the same time, and fiber optic sensors have greatly improved the reliability of high temperature systems to better meet the construction needs of access networks.
Basic description:
1. The main purpose of the reflector is to increase the intensity of the light, while the color filter can change the color and create different effects. Massive luminescence means that the optical fiber itself is the luminous body and will form a flexible light strip;
2. Most optical fibers used in the lighting field are plastic optical fibers. Among different optical fiber materials, the production cost of plastic optical fiber is the cheapest. Compared with quartz optical fiber, the production cost is often only one tenth. Due to the characteristics of the plastic material itself, it is the best choice among all fiber materialsoptical, whether in terms of post-processing or variability of the product itself.
