When measuring, based on the segmented contour line of thread, we used the compiled measurement program to calculate and measure the geometrical parameters of the internal taper thread as pitch, half of thread angle and taper angle. Precisions of pitch, half of thread angle and taper angle reached ±0.012mm,±0.17° and ±0.018°. The results satisfied with the technique requirement of production. The reason of error was analyzed.

We can produce any different pitch blade according to customer needs, the classic value of the pitch: A, 10 degree, suitable brush motor FP helichoper, let lower speeds rotor greater lift; B, 8 degree, suitable brushless motor FP helichoper, can make the main rotor get a higher speed; C, 6.5 degrees, suitable some DIY FP helichoper, can make the helicopter have better lock tail performance with a small diameter and high-speed tail rotor.

桨距可以根据客户需要进行定制，经典的桨距值为：A、10度，适合有刷马达的FP电直，能够在较低的转速下取得更大的升力；B、8度，适合无刷马达的FP电直，能够使主桨获得更高的转速；C、6.5度，适合玩家DIY的FP电直，配合小直径高转速的尾桨，能够获得更好的锁尾表现。

Results show that when improving spot pitch in weld bonded joints with high elastic modulus adhesives, stresses in weld spot zone are decreased while stresses and strains at edges of overlap region are increased slightly. For the joints with low elastic modulus adhesives, both stress concentration degree at the weld spot and the shear strain at edges of overlap region are increased with the spot pitch increasing.

结果表明，高弹性模量胶粘剂胶焊接头中，增大焊点间距，焊点区应力减小而搭接区边缘胶层中的应力应变略有增大；低弹性模量胶粘剂胶焊接头中，焊点处应力集中程度和搭接区边缘胶层中的剪应变值都随焊点间距的增加而增大，增加焊点间距，两种接头的胶层断裂强度都将降低。

The results of the statistic analysis are as follows: 1 The intonation of interrogative sentence is expressed by the change of the pitch of the whole sentence rather than by the sentence final pitch alone; 2 The highest and lowest point of the tone nucleus and sentence final intonation in different interrogative sentences are higher than those of the declarative sentences; 3The difference between the questions in declarative word order and declarative sentence is larger than that between the other kinds of questions i.e.

统计分析的结果表明：(1)疑问语调不是仅仅由句末的音高来表现的，而是通过整句话的音高变化来实现的。(2)与陈述句相比，各种疑问句在语调上的共同特点是调核的调域和句末的调域都较高。(3)不带疑问结构的疑问句因为语调为其唯一的疑问标记，所以与陈述句的差异比带疑问词或疑问句法结构的疑问句与陈述句的差异更大。
