1·The radiation spectrum for relativistic electron moving along curved spiral curve in plasmas is calculated, and also the formula of total energy emitted by a relativistic electron in vacua is derived.
计算了等离子体介质中，沿弯曲螺旋线运动的相对论电子的辐射谱，进一步导出了真空中的能量辐射公式。
2·These may completely change or do away with the landscape of string vacua or with the cascade of bubbles that populate the landscape.
这些也许将完全改变或去除弦真空的地景，或者放弃在地景上聚集成瀑布般的泡泡。
3·Similarly, only a small fraction of the stable vacua are hospitable to life.
同样地，只有稳定真空的一小部份才适合生命。
4·Higher pressures and vacua upon request!
可根据要求所需更高压力和真空。
