: POWER SUPPLY SYSTEM I (1) Nowadays technical progress, including the progress in railway engineering, is unthinkable without the proper power supply system.	(1) Hozirgi vaqtda texnik taraqqiyotni, shu jumladan temir yo'l qurilishidagi taraqqiyotni to'g'ri elektr ta'minoti tizimisiz tasavvur qilib bo'lmaydi	(2) Till recent years, all electric energy has been gene­rated by thermal and hydro-power stations. But the hydro-power stations are always tied to rivers As for the thermal power plants the supplies of fuel needed for their operation are not inexhaustible. So power engineers are now in search of new sources of energy. (3) The great efforts of scientists and engineers have resulted in discovering atomic energy which caused a revo­lution in energetics
(2) So'nggi yillargacha barcha elektr energiyasi issiqlik va gidroelektr stantsiyalarda ishlab chiqarilgan. Ammo GESlar doimo daryolarga bog'langan IESlarga kelsak, ularning ishlashi uchun zarur bo'lgan yoqilg'i zahiralari bitmas-tuganmas. Shunday qilib, energetiklar endi energiyaning yangi manbalarini qidirmoqdalar. (3) Olimlar va muhandislarning katta sa'y-harakatlari natijasida energetikada inqilobga sabab bo'lgan atom energiyasi kashf qilindi.
(4) One of the most significant achievements in the devel­opment of atomic power engineering was made in the Soviet Union in 1954 with the construction of the world's, first atomic power plant (A-power plant). On being put into operation it opened up an epoch of peaceful uses of nuclear energy. [Now the atomic power stations have passed an experimental stage and successfully compete with the con­ventional power stations especially in the countries which experience the energy crisis.	(4) Atom energetikasining rivojlanishidagi eng muhim yutuqlardan biri 1954 yilda Sovet Ittifoqida dunyodagi birinchi atom elektr stantsiyasining (A-elektr stansiyasi) qurilishi bilan erishildi. U ishga tushirilishi bilan atom energiyasidan tinch maqsadlarda foydalanish davrini ochdi. [Hozirda atom elektr stansiyalari eksperimental bosqichdan o'tdi va an'anaviy elektr stansiyalari bilan, ayniqsa, energetika inqirozini boshidan kechirayotgan mamlakatlarda muvaffaqiyatli raqobatlashmoqda.		(5) The main and most remarkable feature of nuclear fuel is that it contains great thermal energy. Indeed, one ton of nuclear fuel is equal to more than 2.5 million tons of coal. Nuclear fuel reduces the cost of electric energy and saves valuable raw materials for other uses. (6) It goes without saying^1 that nuclear energetics is faced with a bright future and very soon we may expect its being turned into the main source of power supply.	(5) Yadro yoqilg'ining asosiy va eng ajoyib xususiyati shundaki, u katta issiqlik energiyasini o'z ichiga oladi. Darhaqiqat, bir tonna yadro yoqilg'isi 2,5 million tonnadan ortiq ko'mirga teng. Yadro yoqilg'isi elektr energiyasining tannarxini pasaytiradi va boshqa maqsadlarda foydalanish uchun qimmatbaho xom ashyoni tejaydi
