The perborate bleaches are not used commercially but are available for use by the consumers. Their bleaching action is similar to that of hydrogen peroxide.
过硼酸盐在工业生产中并不使用，但可供消费者使用，它们的漂白作用与过氧化氢相似。
Based on available frequency standards: one prototype laboratory model of cesium clock, three hydrogen clocks and several (2-6) rubidium clocks, the SO atomic time scale has been established.
利用我们现有的标准，一台试验型实验室铯束标准，三台氢原子钟以及若干台(2 -6)铷气泡标准来建立原子时尺度。
Limitation in available reactor space was compensated by increasing hydrogen recycle or incorporation of other feedstock, which was helpful to controlling temperature rise over the reactor bed.
增大循环氢气量或者混入其它制氢原料，可以有效降低加氢反应温升，弥补反应器的不足。
First, hydrogen is not as easily available as the passage indicates.
首先，氢并不是像阅读部分说的那么容易得到。
