Firstly, the relationship of Atomic force and distance is studied. The scan type of samples and the working mode of probe is confirmed, then PZT is chosen as actuator for micro scan displacement, and optical deflexion method is used to detect the deflexion value of cantilever. After all these work, the system light path design is finished, and its mathematical model is completed.

首先，分析了原子力探针系统的中原子力–距离的关系，并确定探针系统的探针的工作模式和样品的扫描模式，从而选择压电陶瓷作为扫描微位移驱动器；采用光学偏转法检测微悬臂偏转量，并选用了PSD作为传感元件，并在此基础上进行了系统光路设计及其数学模型的建立。

By analyzing the educt and oxide of 〓 powder and BN powder, it is foundthat residual inside the composite is the main cause for the deliquescence of thecomposite and that the boron oxide mainly comes from the BN.

添加烧结助剂，既有效地促进了样品中导电网络的构成，又对〓-BN复相导电陶瓷的电阻率产生很大影响，而且〓配比越接近渗流阀值，烧结助剂的影响越大。

The divers had stumbled upon the most impor tant marine archaeological discovery ever made in Southeast Asia: a ninth-century Arab dhow filled with more than 60,000 handmade pieces of Tang dynasty gold, silver, and ceramics.

这些潜水者无意间碰到了东南亚历史以来最重要的海洋考古发现：一艘9世纪的阿拉伯独桅帆船，装满了超过6万件的唐代手工金、银和陶瓷制品。

This was proven by the discovery of a silt-preserved shipwrecked Arab dhow in the Gaspar Strait near Belitung, which had 63,000 pieces of Tang gold, silver, and ceramics (including a Changsha bowl inscribed with a date:"16th day of the seventh month of the second year of the Baoli reign", or 826 AD, roughly confirmed by radiocarbon dating of star anise at the wreck).

这是证明了，他们发现了一个淤泥保存海难阿拉伯独桅帆船在附近勿加斯帕尔海峡，这6.3万件唐金，银，陶瓷（包括长沙碗刻有一个日期：" 16天的第7个月第二年的宝利统治"，或826年，大致确认了放射性碳测年八角茴香的破坏）。
