极高频

Main products of OMMA are High Frequency Electrotome (DD-2 serials) with independent intellectual property rights and two serial accessories of High Frequency Electrotome, such as Bipolar Diathermy Forceps and Medical Pedal Switch. Bipolar Diathermy Forceps has four regular models, such as gun-shaped forceps, gun-shaped pincett, straight forceps and straight pincett, and subdivides into 48 specs.

On these drivers, I can sense a dip in the high end (10k and up), especially when listening to sources that are normally quite sibilant.

而es3x，我能感觉到在极高频有一些下沉（10K以及以上），特别是当我听一些正常来说带有一些嘶嘶声的讯源的时候（擦玻璃声？！P.S.william曰：不会是底噪声吧==""），能够感受到这一点。

Asia and Pacific Energy Investing will spare no effort in mass producing high-frequency electrodeless lamp, whose focus would be on streetlight energy-preserving industry. Messenger of Light Project, the first phase of their cooperation with Nanjing Kua Shi Ji Group, planned to promote its high-frequency electrodeless lamp to half of Chinese cities within two years, as well as go public at Singapore and Hong Kong.

We performed a simulative test, which confirms that wavelet analysis can separate annual wobble and Chandler wobble. Our results show that this method can be used in astronomical geodynamies effectively. This paper is divided into two parts. The first is about statistic characteristic of polar motion. Polar motion includes secular motion, long period fluctuations, Chandler wobble, annual wobble and high frequency wobble. The secular motion is 3.4mas/year and towards 760W meridian. Long period fluctuations have difference periods in x-axis and y-axis. They are 31.7-year and 24-year in x-axis and 28.5-year and 22.9-year in y-axis. These 2~? decades fluctuations have an amplitude of about 30 mas , and are very nearly linearly polarized, with the observed motion of pole being almost entirely along a line between 360E and 1440W. There is a 55.4-year wobble whose amplitude is 9 mas. The amplitude of the interannual fluctuations is about 4? mas. The amplitude of long period fluctuations decreased after 1970. The annual wobble is a steady wobble. It retrograde wobble is only 1/20 of prograde wobble in amplitude.

本文的工作主要分为两部分：第一部分是通过分析POLE97序列，我们对极移的统计特性有了一个较全面的认识，极移主要包括趋势项、长周期项、Chandler项、周年项和高频项：趋势项的方向是西经76°，速度为每年3.4mas；长周期项中Markowitz 项在X、Y两个方向有不同的周期，它们分别是：X方向的两个周期是31.7年和24 年，Y方向的两个周期为28.5年和22.9年它们叠加在一起是一个线偏振运动，最大振幅约为30mas，偏振方向在西经144°和东经36°之间；极移的长周期波动中还存在一个 55.4年周期的圆周运动，振幅约为9mas；十年尺度变化的振幅在4～6mas之间，在Y 方向十年尺度的成份比较多，它们的周期在X方向和Y方向不是对应的；从七十年代年开始长周期变化的振幅明显降低；周年项是一个振幅稳定的摆动，在X、Y两个方向的振幅略有差别，逆向运动振幅大约为顺向运动振幅的1/20；Chandler摆动的振幅自1900年以来经历了几次较大的变化，其中包括1915年和1955年两次极大值，振幅分别达到0&。25和0&。28，以及1925～1940期间小于0.09的过程，Chandler项在X、Y 两个方向的振幅几乎完全相等，其逆向运动振幅不到顺向运动振幅的1/50。

To do so,they emit extremely high frequency and high-intensity pulses of sound.

如此做，他们散发极高频和高强度脉冲声音。

Millimeter wave refers to extremely high frequency (30-300GHz) electromagnetic oscillations.

毫米波是指波长1—10mm，频率在30—300GHz的极高频电磁波，它具有广泛的生物学效应。
