Statistical Energy Analysis is a module measure, which use relationship of energy flow to evaluate dynamics, vibrating response level and sound radiation of the mulriple and syntonic assembly structure.

统计能量分析是个模块化方法，它运用能量流关系式对复合的、谐振的组装结构进行动力特性、振动响应级及声辐射的理论评估，SEA特别适用于高模态密度的高频区，传统的数值计算方法如有限元和边界方法对应力和振动建模获得了很大成功，但对噪声应用存在明显的局限。

Research shows turning round vibration is the main vibration shape of system of direct empty cold construction, should consider fan of; of vibration shape coupling many a little bit the structural vibration that syntonic drive causes is answered lesser, movement of fan low frequency is more than the influence of high frequency movement to the structure to structural influence.

探究表明扭转振动是直接空冷结构体系的主要振型，应该考虑振型耦合；风机多点谐振激励引起的结构振动响应较小，风机低频运转对结构的影响大于高频运转对结构的影响。

Air wire is a important component of radio controller , it is composed of the series-parallel connection syntony circuit by day coil and capacitance, with rapid and intense high frequency interface coupling, one side needs and the card parameter mates, the feasible card is able to get the sufficient energy and the entire data , the data taking-over returns and with the card responding to , another aspect will mate with to enlarging a circuit again , makes the radio controller gain sufficient electric energy in the process of read-write card.

天线是射频控制器的一个重要组成部分，它由天线圈与电容组成串并联谐振回路，与高频接口紧密耦合，一方面要与卡片参数匹配，使得卡片能够得到充足的能量和完整的数据，并且把卡片的响应数据接收回来，另一方面又要与放大电路匹配，使射频控制器在读写卡过程中获得足够的电能。

It is called high-frequency trading — and it is suddenly one of the most talked-about and mysterious forces in the markets.

这种被称作高频交易的方法突然成为了市场上广为关注的神秘的力量。

Influence of two depolarizing agent s on the electrical performance of wet tantalum capacitors is studied in this paper.

研究了两种去极化剂对液体钽电容器在高频电路中电性能的影响。

WZC series lacrimal major therapeutic apparatus for the treatment of various types of lacrimal duct obstruction, tear Explorer obstruction, nasolacrimal duct obstruction and chronic dacryocystitis by the Ophthalmic Center Sun Yat-sen University Professor Dr. Wang Zhichong research, with Professor Wang invented the 'high-frequency lacrimal dredging operation ', the treatment of traumatic small, easy-to-use, low cost.

WZC系列泪道治疗仪主要用于治疗各种类型的泪小管阻塞、泪总管阻塞、鼻泪管阻塞和慢性泪囊炎，由中山大学眼科中心教授王智崇博士研制，配合王教授发明的'高频泪道浚通术'，治疗创伤小、易操作、费用低。
