Though the medical image techniques of the present day, such as CT and MRI, produce images with good quality, the great expense for necessary equipment and the long time required for obtaining image data make these techniques unhandy.

在现今的医学影像领域中，CT和MRI虽然拥有相当良好的影像品质，但由於仪器昂贵和呈像时间较久，所以使用上有其不便之处；反观超音波影像不但取像快速，且成本较为低廉，因此已经成为一项重要且普及的诊疗技术。

We discuss the effect that disk scheduling algorithms have on the disk bandwidth and buffer that is needed in retrieval of video, present algorithms for buffer management, disk scheduling and admission control, and probe into the technology for the storage of scalable compressed video data.

为了实现视频数据的优化存储与回取，本文对MPEG流的结构及传输特性进行了讨论，分析了现有磁盘系统的读取过程和延时特性，建立了用于对连续媒体回取过程进行分析的磁盘传输延迟模型。

It should be noted that while many of these innovation are ascribed to Vitry, and somewhat present in the Ars Nova treatise, it was contemporary-and personal acquaintance of de Vitry, named Johannes de Muris who offered the most comprehensive and systematic treatment of the new mensural innovation of the Ars Nova(for a brief explanation of the mensural notation in general, see the article Renaissance music) many scholars, citing a lack of positive attributory evidence, now consider "vitry's" treatise to be anonymous, but this does not diminish its importance for the history of rhythmic notation.

需要指出的是虽然Vitry拥有如此之多的革新，并且有些都体现在《新艺术》这本专著中，但是他的同龄人和熟人--Johannes de Muris为他《新艺术》中新的度量记谱法提供了最为广泛和系统的论述，很多学者引证了有效归属的缺失，所以现在认为《新艺术》这本专著的作者是无名氏，但是这一点并不能减弱它在节奏记谱历史中的重要性。

In the present study, the effect of salinity on the germination for euhalophyte and xerophyte, and the strategies for adaptation of halophytes to extreme saline and arid environments in Xinjiang during seed germination stage were investigated;the osmotic adjustment traits of euhalophyte and xerophyte were also investigated in field and controlled conditions.
