聚变温度

The gaseous impurities in the alloys were well controlled with the sum of C, N and O less than 500wppm. For the first time it was found the strong interaction between Cr-Ti-CON, which reduces the mobility of Ti and CON, enhancing high-temperature strength and the aging-hardening property, and keeping the cold-work induced hardening at higher temperature. Aging-hardening could increase the tensile strength of V-4Cr-4Ti by 30% and could be utilized at 00 C for better economical performane of a vanadium structure. Hydrogen release will occur for the alloys tensile loaded at room temperature, which will affect the safety of a vanadium structure due to the resulting dimensional instability. For hydrogen embrittlement, impact toughness and fracture toughness of the alloy showed higher sensitivity than the tensile test elongation,so the toughness should be used as a new standard for the assessment of the embrittlement. Vanadium alloys were easily oxidized in air.

合金的气体杂质含量得到有效控制，C、N、O总量低于500wppm；首次发现Cr-Ti-CON之间的强相互作用，它使Ti、CON的高温可移动性降低，提高合金的高温强度、增强时效强化特性、使冷加工强化保持到更高温度；时效强化可使V-4Cr-4Ti的强度提高30%，可在低温（00C）下应用，提高构件的经济性；室温下，钒合金在拉应力的作用下，存在着氢释放，带来部件使用中的尺寸不稳定性，影响构件安全；氢脆是钒合金聚变应用的一个关键问题，合金的冲击韧性和断裂韧性表现出比拉伸延伸率更强的氢脆敏感性，应作为评价合金氢脆行为的新标准。

A planet on the other hand is built up out of the dust that surrounds a star. When a star is formed there is still a disk of gas surrounding it. As this gas cools, it condenses and forms solid grains. These grain particles accrete into large bodies called planetesimals, which then collide and accrete to make protoplanets. These protoplanets evolve into planets like the planets in our own solar system.

行星演化与恒星不同：恒星形成之后，周边的气体尘埃云冷却之后凝结形成，成为行星雏形，众多小行星雏形聚合碰撞，演化成成熟的行星；没有内部的核聚变；质量超过木星13.6倍，就会产生核聚变，如果还未至木星86倍，尚处于棕矮星的阶段，将会向恒星演化；持久的核聚变需要足够大的质量来支撑，温度也不足支撑氢向氦的转变。
