Three-phase embed electrode salt bath furnace use the salt class as heating impregnant, according to the different operating temperature, could select different ingredient salt or compound salt, the salt is not electric beforemelting, therefore the salt bath furnace must use the starting-electrode to melt when using, because the electricity bring quantity of heat unceasingly through electric dissolving salt, so can maintain the dissolving state, because of electrode under the electromagnetic effect,make the dissolving saltcycle unceasingly through natural convection and magnetism mix round,therefore can well-proportioned heat workpiece rapidly.

三项埋入式电极盐浴炉采用盐类作加热剂，根据不同的工作温度，可选用不同成份的盐或混合盐，盐在熔化前是不导电的，因此盐浴炉使用时必须使用起动电极溶化，由于电流通过导电的溶盐不断产生热量，故可保持溶化状态，因电极在电磁力的作用下，通过自然对流和电磁搅拌而使熔盐不断循环，故可迅速和均匀的加热工件。

In this thesis, the radiation principle and the structure of slot antenna are studied and the impacts on its performance of every structure parameter in a slot antenna design are analyzed. On this foundation, a design plan of planar slot array antennas is proposed. The design has some structural feature as follows:(1) with different dielectric layers and microstrip line structure to guide the electromagnetic wave effectively;(2) the feeding network formed of microstrip line can match with the radiating slots expediently;(3) in order to increase the bandwidth of the antenna, the wider slot and branched feeding microstrip line are adopted to form a double resonance.

本文对缝隙辐射的原理、缝隙天线的结构作了探讨，分析了缝隙天线设计中各结构参数对其性能的影响，并在此基础上提出一种平面型缝隙天线的设计方案，它具有以下的特点：(1)采用分层结构，以不同的介电系数和微带线结构形成对电磁波的有效引导；(2)利用微带线构成馈电网络可以方便地与辐射缝隙进行匹配；(3)增大缝隙的宽度，并利用馈电微带线的枝节形成双谐振，以增加天线的带宽。

It is because through the apertures the exterior electromagnetic field will couple with the cavity, and excite resonance in the cavity.

甚至在空腔中特定位置有著比无屏蔽时更大的场，对於封装内的电路构成额外的干扰。

It is amended and perfected so that it can be used to analyze the transmission characteristics of the arbitrary metallic waveguide filled with symmetrical and non-symmetrical dielectric, metallic resonance cavity with the arbitrary shapes, and other boundary value problems of the electromagnetic field.

本文对上述方法进行了修正、丰富和完善，使其可以较方便地分析填充均匀和非均匀介质的任意横截面金属波导的传输性能和任意形状金属谐振腔的特性以及其它一些电磁场边值问题。

A seven-node difference scheme of the diffusion equation was proposed to study the behaviors of transient electromagnetic field in complicated 3-D geoelectric body. Models of roadway and anomaly body were set up for simulating the transient field excited by a vertical magnetic dipole source. The result of numerical simulation shows that the presence of low resistive conductor leads to noticeable distortion of isolines for the "smoke ring" field, whereas the distortion is not so obvious where the roadway and the poor conductor are located.

为了探讨复杂三维地电体中瞬变电磁场的响应特征，推导了三维扩散方程的七点差分格式，建立了巷道和异常体模型，并对垂直磁偶源激发的瞬变场进行了数值模拟，观察到早期&烟圈&场在低阻体处等值线发生的明显畸变，在巷道和高阻体处的畸变较弱，随着时间的增加异常体的影响逐渐减弱。
