11. This is surrounded by a transition region of rapidly increasing temperatures, and finally by the super-heated corona. 12. "' Coronal loops "'form the basic structure of the lower corona and transition region of the Sun. 13. Nanoscale structures that appear naturally in the materials'transition region can suppress thermal radiation as the temperature rises. 14. It is composed of four distinct parts : the chromosphere, the transition region , the corona and the heliosphere. 15. He earned transition region and corona. 16. Spacecraft studying the event include the European-American Solar and Heliospheric Observatory and NASA's Transition Region and Coronal Explorer. 17. A transition region ( domain walls ) is formed between domains, in which the magnetic field exits the material. 18. There are also three additional euchromatin / heterochromatin transition regions for a total of four on the Y chromosome. 19. In the case of pronounced adsorption it is advisable to choose x'close to the right border of the transition region . 20. Between the photosphere and the corona, is the thin region through which the temperature increases known as the transition region .
