1, Their point of tangency is called the pitch point, and since it lies on the line of centers, it is the only point at which the tooth profiles have pure rolling contact.

2, The friction coefficient at the pitch point is not a monotonic quantity of the rational speed or the load, instead of having a maximum value.

3, The network transmission function displays in the pitch point for the level correspondence structure,(http:///pitch point.html) see Figure-2.

4, Pitch Point is the intersection of the spline tooth profile with the pitch circle.

5, In the P2P network, each participation pitch point not only is the server also is the client, not only is the information Provider also is the information consumer.

6, P2P(Peer To Peer) means each pitch point in the distributional system is logically coordinated.

7, Based on the pitch meshing theory of the worm drive, a new structure of the cylinder worm drive-the double pitch point and double side-placed worm gear drive is proposed in this paper.

8, From the collaborative theory angle, the author has analyzed Virtual Reference Desk (VRD) of the work flow each work pitch point collaborative relations.

9, Taking bus control unit SJA1000 as the core, we have realized the intelligence control pitch point which is the lower position machine design.

10, The maximum pressure, the maximum friction coefficient and the highest film temperature all occur in the vicinity of pitch point.

11, As the wireless sensor network main entity, the sensor pitch point has two kinds of functions: The sensing measures of the data and the network transmission function.

12, The key of policy- making tree production algorithm which is from top to bottom is the pitch point attribute value.

13, In order to improve the performances of sensing devices, the approach of enlarging and deepening the pitch point aperture of resonant beam has been utilized.
