However, because traditional database bottom can not deal with unstructured data, a wey that deal with unstructured data need be presented.

为了解决这个问题，很多研究者提出了为web数据建立元数据，可将非结构化数据变成结构化或半结构化数据。

The samples of 600℃ group didn't crystallize, but the color became darker and yellower as the peolongation of the heating time; the samples of 650℃ and 700℃ groups crystallized in different degrees, the translucency and Chroma decreased as the prolongation of the heating time, but the Value increased.

Cavitation is the most distinct characteristic of the high-power low-frequency ultrasonic fields, and it is also regarded as the primary mechanism of ultrasonic cleaning. Nevertheless, the measurement question of the high-power low-frequency ultrasonic fields hasn't been resolved well, because of the incomplete cavitation theory and the complexity of cavitation fields. The universal acceptant standard measurement hasn't been found up to the present so that it is difficult to judge of the performance of ultrasonic cleaning machines scientifically.

大功率低频超声场最鲜明的特点就是空化，而空化也被认为是超声清洗的主要物理机制，但由于其理论研究尚不完善，加之空化声场的复杂性，使得至今大功率低频超声场的测量未得到很好的解决，尚未找到一种与清洗效果有确定关系的普遍适用的标准方法，使得在客观地评判清洗机优劣时很困难。
