When the self-etched adhesives (Contax, Clearfil TRI-S Bond) were used for the surface treatment of sclerotic dentin, the results of thermal circlings showed that, for Contax, 5,000 times thermal circlings did not weakened the bond strength, while the bond strength after 10,000 times thermal circlings significantly lower than that before circling; for Clearfil TRI-S Bond, 5,000 times thermal circlings significantly weakened the bond strength, while 10,000 times thermal circlings weakened it further.

Because of special geometry structure of three-cone bit, the top of formation will form a tri-spine well bottom while drilling with three-cone bit the drill string. It is the tri-spine well bottom that leads to the axial harmonic of vibration when the bit revolves a round and the three concavo-convex heave of bit and formation result in one time (1×rpm),two time (2×rpm), three time (3×rpm) turning table speed.

高岩由于三牙轮钻头的特殊几何结构，钻进过程中在岩层顶部容易形成一个三脊状井底，正是这一三脊状井底，当钻头旋转一周时钻柱轴向三次凸凹变化，由此在轴向产生1倍、2倍和3倍及其更高次倍于转盘转速rpm的谐波振动。

高岩摘要：由于三牙轮钻头的特殊几何结构，钻进过程中在岩层顶部容易形成一个三脊状井底，正是这一三脊状井底，当钻头旋转一周时钻柱轴向三次凸凹变化，由此在轴向产生1倍、2倍和3倍及其更高次倍于转盘转速rpm的谐波振动。

Time (3Xrpm) turning table speed. In addition, while the teeth of the tri-cone bit interact with the formation, the drillstring will generate tiny axial vibration. As the vibration is symphonious to the tri-spine well bottom, the vibration signal exhibits amplitude modulation character. This character had been verified by in-site measurement data and numerical simulation.

另外，三牙轮钻头与地层作用破岩时牙轮牙齿产生啮合振动，由于三脊状井底对啮合振动进行幅度调制形成调幅信号，根据调幅信号的频率特征，振动信号在频域表现为具有一定边带的一束谱线，它是钻头工作正常的&健康信号&。

In the"willow leaf"TEM horn, the characteristic impedance varies from 50Ω to the 377Ω free space impedance, thus its metal plates have shapes similar to willow leaf. The constant impedance TEM horn consists of two tri-angular metal plates, with it's characteristic impedance at arbitrary cross-section being a constant.
