时间间隔

It is an new approach of time interval and frequency measurement, which can be used to measurement short time interval by detecting the phase coincidence point between the signal and its transfer delay with related length.

这一理论利用信号的时——空关系通过对被测时间信号与其在长度空间上传输延迟的重合检测来测量短时间间隔，依此为基础可完成各种时间间隔与频率测量仪器。

The basic characteristics of the whole process were gained. When the seedling falling out of the tube feet, the difference of the time interval between 2 neighboring seedlings wasn't notable, and the difference of the time interval of 2 neighboring seedlings wasn't notable and the agricultural time was not special notable. These results showed that the uniformity of the pneumatic ordered throwing transplantation was excellent and could meet the demands from design and agriculture; Upstanding state was primary as the seedling falling out of the tube feet, it showed that the seedling could keep erective preferably when the seedling falling to the field.

结果表明：钵体苗从导苗管管脚中落出时，相邻2株钵体苗落出时的时间间隔差异不显著，从左中右3个管脚落山的相邻2株钵体苗的时间间隔与农艺要求的时间差异极不显著，说明气力有序抛秧均匀性好，能满足设计要求和农艺要求；钵体苗从导苗管管脚落出时以直立状态为主，表明气力有序抛秧的钵体苗落入田间时能较好地保持直立。

This Paper discusces the fundamental Principle and design of the electronic millisecond difference exPloder.

本文讨论电子毫秒微差放炮器的基本原理及设计，此仪器能按一定时间间隔向电雷管组供给电流脉冲，它的优点是：(1)时间间隔可在1毫秒至500毫秒范围内调节，调节手续很简单。

This is a significant improvement as compared to the previous free-running 4.6μs of SDH. The proposed method demonstrates an outstanding capability not only in reducing relative time interval error but also in stabilizing RTIE.

而且在相对时间间隔误也同样有出色的表现，以线性表示相对时间间隔误与时间的关系图中，亦能看出变化趋於平稳。

An object receives in proportion to its speed resistance, and only receives its force of inertia the impetus, but the movement, through the isotopic dielectric, divides into the time the equal gap, forms the geometric series in time each time-gap's start's speed, but during passed over gently and swiftly distance in proportion to this speed.

Condition: If an object receives in proportion to its speed resistance: and only receives its force of inertia the impetus, but movement: conclusion: Through the isotopic dielectric, divides into the time the equal gap, forms the geometric series in time each time-gap's start's speed, but during passed over gently and swiftly distance in proportion to this speed:.

The present invention relates to a method for heuristically starting up DC brushless servo electric machine, including the following steps of (1) after powerup of an increment type photoelectric encoder, electrifying a stator winding two by two with identical time interval to generate six-directional stator winding resultant magnetic fields;(2) detecting six different angles rotated by the rotor within identical tiny time interval by the photoelectric encoder;(3) selecting most positive value rotation angle from the six different angles, and determining maximum torque corresponding to the stator winding resultant magnetic field, and implementing servo startup using the maximum torque as constant starting torque;(4) after the zero-point signal of the photoelectric encoder occurring, switching to servo operation with normal constant torsion.

本发明直流无刷伺服电机试探启动方法，采用如下步骤：(1)增量式光电编码器上电后对定子绕组采用相同的时间间隔两两通电，顺序产生六个方向的定子绕组合成磁场；(2)由增量式光电编码器检测出转子在相同的微小时间间隔内分别转过的六个不同的角度；(3)从转子六个不同的角度中选出最大正值的转角，确定相应定子绕组合成磁场对应的最大转矩，并以该最大转矩为恒定启动转矩进行伺服启动；(4)当增量式光电编码器零点信号出现后，切换为正常恒转矩伺服运行。

A control unit times the interval between the pulses and compares these timings with a stored value representative of a predetermined multiple of the minimum time.
