查询词典 frequencies

The natural frequencies, the equation of motion and the node of vibration are discussed for the vibration system of a cradle dynamic balancing machine. Some general remarks concerning the design are make. An analysis by the method of four measuring plane are given together with the actual electric circuits. Furthermore, the general ideas about the KQD-1 type cra-dle dynamic balancing machine are introduced as an example.

In encounters paired between unfamiliar males and males, there is great difference between dominant male and subordinate one. The dominants approached, attacked and chased the subordinate more often and spent significantly longer time.The subordinates defend or escaped the dominant more often and spent significantly longer time, but there is no significant difference on nonsocial behaviors between the dominant individual and the subordinate one.Frequencies of aggressive and social investigating behaviors are positively correlated with body mass.

结果发现，当陌生的两只雄鼠相遇时，优势雄鼠和从属雄鼠间的社会行为有明显的区别，优势鼠接近、攻击、追赶对方的频次和持续时间明显的多于从属鼠，而从属鼠逃离和防御行为多于优势鼠；优势鼠的体重明显的大于从属鼠，而且攻击行为和社会探究行为的频次与体重呈正相关，非社会行为无明显的差别。

With the method suggested in this paper the transition frequencies between nucleate and film boiling have been calculated.

按照本文提出的方法计算了膜沸腾产生所对应的频率，在四个不同的磁化场条件下所得结果与实验符合较好。

As the address of EEPROM, which was used for looking2up table, the information of octant and signals of magnetic encoder which were converted by A /D converterwere dealt by FPGA. And the frequencymultip lication formagnetic encoderwas comp leted. So the resolution and accuracy ofmagnetic encoderwere imp roved, 4096 multip le frequencies can be achieved in per cycle.
