Fused silica is an excellent glass but expensive because of pure silica's very high melt ing point.

熔硅玻璃是极佳的玻璃，但由于纯硅的熔点很高，所以制造费用昂贵。

The high-silica glass with SiO〓 content more than 96% are similar in many kinds of properties to pure silica glass.

高硅氧玻璃中SiO〓含量超过96％，性能接近纯石英玻璃，因此高硅氧玻璃在多种用途上可替代石英玻璃。

AMOC results reveal that S parameter of three lifetime components in oxygen are all bigger than that in nitrogen atmosphere. These are probably caused by the oxygen making the spin-conversion of positronium atoms.

结合正电子寿命-动量关联谱测量结果，本工作分析了不同气氛下多孔硅样品中电子偶素湮没寿命及动量变化关系，讨论了多孔硅中电子偶素的湮没机制以及气氛对孔径计算理论模型的影响。

The longest lifetime component in PALS results is ascribed to the annihilation of positronium in cavities of PS sample. It is found that 80% of the positrons implanted in PS film have formed positronium atoms. PALS results show that the lifetime of ortho-Positronium has small value when the sample was in oxygen gas medium compared with those in other medium.

正电子湮没寿命谱测试结果表明，样品中存在长达40ns的电子偶素湮没成分，并且进入多孔硅膜层的正电子约有80%形成电子偶素，具有非常高的电子偶素产额；在氧气气氛下，由于气体导致o-Ps发生自旋转化猝灭是使多孔硅样品中电子偶素寿命缩短的主要原因。

Different from the perieutectic reaction Liq+δ→β, perieutectic reaction in Al-Si alloys containing Mn acts as Liq+δ→α.

与铝硅铁三元系中的包晶反应Liq+δ→β不同，加锰铝硅合金中δ铁相的包晶反应则以Liq+δ→α的形式进行。

At the present time, their size has arrived at nanometer scale, and it approximately takes several picoseconds, or even shorter time, for free carriers to transport during such small distances. Therefore, research of carrier dynamics in silicon on shorter and shorter time scale is urgently developed. Processes on such short time scale are difficultly measured by traditional electronic method, so ultrafast spectroscopy method is the only choice of carrying out such experiments. Additionally, application of photoelectric detectors is severely influenced by laser.

近年来，硅半导体器件尺寸不断变小，目前已经缩小到了纳米尺度，载流子在这个尺度内的输运时间大约在ps量级，这促使人们需要对越来越短的时间尺度内硅的载流子动力学进行研究，传统的电子学方法很难对这么短时间尺度内发生的现象进行测量，超快光谱探测几乎成了进行这类研究的唯一测试手段。
