According to the features of dielectric barrier discharge, the load characteristics of the dielectric barrier discharge type ozonizer were analyzed with the load voltage assumed to be sinusoidal.

实验发现：在铪膜生长时，轰击铪膜的Ar+离子的能量、入射角度和束流密度对薄膜的晶粒取向有很大的影响。

As Hf is added into the alloy the volume fraction of γ/γ′eutectic is increased and the temperature range between solidus and liquidus is expanded, which may maintain the effective linkage of interdendritic capillary feeding channel, thus improving the resistance of DS castings to ...

铪的加入，增加了共晶γ/γ′的体积分数，扩大了凝固范围，改善了合金凝固后期的毛细补缩通道的联系，从而减轻了热裂倾向性。随着铪含量的提高，合金的中温持久性能，特别是中温横向持久性能有所提高。

This implies a major stage of crustal growth in Proterozoic time and remelting of the crustal material in Early Jurassic time;(5) The Oligocene-Miocene adakites contain magmatic zircons that show similar Hf isotope compositions to the Cretaceous-Paleogene Gangdese batholiths, providing a key constraint that allows evaluation of the nature and timing of crustal thickening in southern Tibet owing to the India-Asia collision; and (6) As a whole, the Hf isotope information observed in zircons from the above Transhimalayan rocks demonstrates a temporal variation in εHf values, and thus TDMC ages, that suggests multiple stages of orogenic or crustal formation events.

五、渐新世、中新世的埃达克岩，其岩浆锆石的铪同位素特徵与白垩纪、古第三纪冈底斯岩浆相似，因而为藏南在印亚碰撞以后，地壳增厚的时间与机制提供了关键性的制约；六、综观上述藏南火成岩中的锆石，它们与时变化的铪同位素初始值及其对应的模式年龄记录了拉萨地块多阶段的造山与地壳形成历史。

We discussed possible origins of the additional scatterings, which might be attributed to the trapped charges, fixed charges, soft phonons, and crystallization in the HfO2 films and HfO2/poly-Si channel interface.

我们讨论了其他发生散射的原因，其中可能是存在於二氧化铪薄膜中和二氧化铪薄膜与多晶矽通道介面间的缺陷电荷、固定电荷、微弱声子、和薄膜结晶化所造成的。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
