求翻译：太阳的能源来自于其核心部分。太阳内核的温度高达1500万摄氏度，压力超过地球气压的340亿倍。内核的气体密度极高，是水的150倍。太阳每秒钟向外辐射约28600亿亿兆瓦的能量，这么高的能量是由其内核的核聚变反应产生的。在聚变中，四个质子聚合成一个氦原子核。氦原子核的质量比四个质子小0.7%，失去的质量转换成了能量，以伽玛射线的形式被释放到太阳的表面，并向宇宙空间辐射出去。太阳每秒钟约有七亿吨的氢被转化成氦。在此过程中，约有五百万吨的净能量被释放。能量在对流过程中不断地发出光和热，使太阳发光。从太阳内核释放出的能量需要经过几百万年才能到达表面。是什么意思？

Solar energy from the core part. Solar core temperature of up to 15 million degrees Celsius, pressure for more than 34 billion times times the Earth's air pressure. Kernel-the gas density is extremely high, 150 times times that of water. Sun to radiation about 2.86 trillion MW of energy per second, such a high energy is generated by nuclear fusion reactions in its core. In fusion, four protons into helium nuclei. Quality 0.7% smaller than the four protons of the helium nuclei, the lost mass converted to energy, in the form of gamma-ray were released into the surface of the Sun and space radiation out. Every second the Sun about 700 million tons of hydrogen are converted into helium. In the process, about 5 million tons net energy is released. Energy in process of convective constantly sends out light and heat, make the sun shine. Kernel release the energy from the Sun need through millions of years to get to the surface.
