the speed measurement of various types of thin-disc ultrasonic actuator, we attach

the light-reflection plate at its rotor, and use xx as the detection device to

send and detect the UV light on the light-reflection plate. The pulse signal

gained by OMRON E3X-A11 is calculated and shown by

the HP 34401A Multimeter, then we can get the actual rotation speed of various

types of thin-disc ultrasonic actuator. The proto-type structure of thin-disc

ultrasonic actuator is shown in picture 6, and the photo of experimental

structure of roation speed measurement is shown in picture 7[1].

The

comparison of rotation speed of various types of thin-disc ultrasonic actuator

is shown in table 1. the measurement of the rotation speed is based on the

input impulse signal which is set as the system resonance frequency in table 1.

The result is got under the condition that the input voltage is 15V, input

current is 0.2A, rotor-weight is approximately 100g and preload id 30gf. About

the structure of two-phase, three-phase-eccentric and three-phase symmetric

thin-disc ultrasonic actuator which are designed in this text, the consumption

power is about 1.5W. By the example of the temperature and rotation test in the

xx motherboard of Intel Pentium 4, we find that under normal operation of the

computer, the rotation speed of the CPU fan only needs to be kept at 3497 rpm

(as shown as the yellow curve in picture 8(a)) to achieve the effect of stabilizing

the operation temperature (as shown as the yellow curve in picture 8(b)).

As shown in picture 8(a), it is the dynamic

curve of CPU fan that use the ASUS PC Probe to detect. In the picture, the blue

curve is the minimal threshold rotation speed of the CPU fan (program use 600rpm

as default). And as shown in picture 8(b), the blue curve id the highest

temperature threshold value (program use 80°C/176°F as default).

In this picture, the operation temperature of the CPU is always kept at 24°C/75°F which is caused by the environmental temperature. The designed thin-disc ultrasonic actuator in this text already has the capability to be the rotation-speed standard of CPU fan.

我了解 我有試著找翻譯社 但是價錢實在不是一個研究生負擔的起...偏偏我家老闆又.....不願意花錢~~~ 我自己其實有翻 但真的翻不好 所以才放到知識+ 若真的沒有人幫忙 我想也只能拿我自己翻得亂七八糟的英文給老闆了 呵呵

不難翻，可是專有名詞很多，翻譯需要花一點時間及功夫。

你在這問，可能會找到一堆軟體翻出的答案，你要準確的解答最好找翻譯社翻!
