The most achievement is that we firstly obtain the analytic accurate solution of the modal fields of the waveguide structure and find some available character : ( 1 ) the different uniaxial crystal materials have the different propagation properties ; ( 2 ) when the optical axis of the crystal is on the plane that is made up of the normal direction of the waveguide plane and the propagation, there are te mode and tm mode in this special waveguide, but the principal mode is different of the character of the uniaxial crystal, the principal mode is the principal mode of te mode for the negative uniaxial crystal, but the one of tm mode for the positive uniaxial crystal ; ( 3 ) when the crystal optical - axis parallel to the waveguide plane, for the positive uniaxial crystal material, the principal mode of the waveguide is a te wave, which can be excited by the light at any frequency ; when the light frequency satisfies a single mode propagation condition, there will be only the principal mode propagating in the waveguide, otherwise some of the higher order modes can be excited, which are neither te modes, nor tm modes, but the hybrid guided modes
本文就是在此背景下，利用金屬波導和單軸晶體的一些特性，結合麥克斯韋方程組和波導的邊界條件，從三種不同的情況研究了光在對稱平面單軸晶體金屬波導（波導層是單軸晶體，兩個波導界面均為金屬）內的傳輸特性，其主要貢獻為，首次解析地得到了這種波導結構下模式場的精確解，並發現了一些有用的特性： （ 1 ）模式場的性質因單軸晶體的性質不同而異； （ 2 ）當單軸晶體光軸位於波導界面法方向與傳輸方向構成的平面內時，波導中傳輸te波和tm波，只不過其主模因單軸晶體的性質不同而異，當波導層介質為負單軸晶體時，波導主模是te波主模，而波導層介質為正單軸晶體時波導主模是tm波主模。 （ 3 ）當單軸晶體光軸位於波導面內時，對于正單軸晶體，波導的主模是橫電波te _ 0模，任何頻率的光波均可激勵該模式；當光波波長滿足一定條件時，波導內傳輸單模，否則，將激勵起高階模式，高階模即匪te波，也匪tm波，而是兩者耦合而成的混合模。As for cathode of mercury - free alkaline zinc manganese - dioxide battery, mono - layer plating of in, zn, sn and double - layer plating of zn - in, sn - in, zn - sn was electroless deposited on the surface of current collector respectively

高壓斷路器所造成的事故無論是在次數，還是在事故所造成的停電時間上都占據總量60以上。因此，及時了解斷路器的工作狀態對提高供電可靠性有決定性意義；並可以大大減少盲目定期檢修帶來的資金浪費。本文論述了斷路器機械特性參數監測方法；提出了二次迴路保護器的概念，並將跳、合閘線圈完整性監視和二次迴路保護結合起來，給出具有完整性監視功能的二次迴路保護器實現方案；根據斷路器生產廠家提供的斷路器額定短路電流分斷次數，計算每次分閘對應的觸頭電壽命損耗，預測觸頭電壽命；提出根據斷路器殼體溫度和斷路器周圍空氣溫度結合斷路器熱阻來計算斷路器主觸頭穩態溫升的方法，並根據此時的負荷電流間接計算主觸頭迴路的電阻；在硬體電路設計上，採用美國ti公司最新推出的一種功能強大的單片機msp430 ，並充分考慮該晶元的適用電壓范圍給設計帶來的特殊問題；在通信模塊的設計中，解決了不同工作電壓晶元之間的介面問題，並給出了直接聯接的接線方案。The researching result is shown that an electron divided equally trend and an action of bond forming exist in brass atom and zinc atom in brass substtate. so, the electro - negativity equilibrium principle developed by sanderson et al, may be extend to the system such as brass under different conditions. the electro - negativity equilibrium was produced during the process from pure brass and pure zinc to brass - zinc alloy, and the difference of chemical properties between alloy and pure material is great
結果顯示黃銅中銅鋅原子間存在一定的電子「均分」趨勢，使銅鋅原子間存在一定的成鍵作用，可以將sanderson等人提出的「電負性均衡原理」有條件地推廣到黃銅這類合金體系中，正是這種銅鋅形成合金時所產生的電負性均衡，使得黃銅中的銅鋅與單質狀態下的銅鋅相比，在化學性質上發生了差異，且增強了黃銅的穩定性，限制了黃銅中的鋅在鍍液中滲出。Zb transformer substation named european style cubical substation, which as a new type of electricity supplying equipment, with more advantages than traditional substation, because of small dimension, compact structure, and decreases the construction cost, at the same time, its installation is very easy, and the supply is very fast, and no need watching people, especially it is into the load center, which is very important for improving the supplying quality, decreasing the loss, improving supplying reliability and reforming electricity network
Zb型箱式變電站谷稱歐式箱變，作為一種新型供配電裝置，它比傳統土建變電站具有許多優越性。由於它體積小，佔地面積小，結構緊湊，便於搬遷，因而大大縮短了基建的周期和佔地面積，也減少了基建費用。同時，箱式變電站現場安裝簡單，供電迅速，設備維修簡單，無須專人值守，特別是它可以深入負荷中心，對提高供電質量，減少電能損失，增強供電的可靠性以及對配電網路改造都是十分重要的。分享友人
