窄禁帶-
The technology of alternating - current - boosting by way of constant current is successfully used to charge capacitors with 25 kilojoules of energy in only eight seconds. rail - gap switch with performances of long life and highly steady state are designed. and the high voltage pulse generator, which can produce low - excursion and fast - rise pulses, are designed by using double trigger circuit and hydro - thyristor as switch
在大功率恆流充電技術上，成功的應用了交流調壓式恆流技術，可以在8s內讓電容器儲存25kj的能量;設計出了長壽命、高穩定的軌道開關;採用氫閘流管做開關，使用雙觸發電路，研製出了低抖動、快前沿的高壓脈沖發生器（點火機） ;採用單片機和pld ，研製出了精度為10ns的延時同步機。 -
Water dielectric pulse power modulator has been widely applied because of its merits of high energy storage density, compactness, and capability to drive low impedance high power microwave sources. research for multi - pulse operation of high power spark gap switch with high current and comprehending its physical properties are the basis to study multi - pulse operation or repetitive operation of water dielectric pulse power modulator
水介質脈沖功率調制器具有儲能密度高，結構緊湊、與低阻抗微波源較好匹配的特點，因此得到廣泛的應用，但是受到高功率、大電流氣體開關的絕緣恢復的影響，水介質等低阻抗脈沖功率調制器的重復頻率運行或多脈沖運行受到較大的限制。 -
We put our emphases on four sections : the opening of the energy gap and its effects on the thermodynamic properties in low temperature, quantum fluctuation and the hidden long - distance order parameters, the magnetization and the specific heat properties under the extern magnetic field of the ferromagnetic chain, and the energy spectrum of the ferromagnetic ladder
著重研究在一維量子自旋系統中的能隙的打開、以及能隙對系統熱力學性質的影響；量子漲落和系統隱含的序參量；亞鐵磁的在外場下的磁化性質以及比熱性質；和亞鐵磁雙鏈系統中的能譜。 -
Zno is promising : high - quality zno with very low defect densities can be synthesized at much lower temperature ; zno can emits light with shorter wavelength than blue light emission from gan ; zno has higher excitonic binding energy promising strong photoluminescence from the bound excitonic emissions even at room temperature ; by alloying with mgo, tuning of the band gap while keeping the zno hexagonal structure can be achieved by forming mgxzn1 - xo. as we know, band gap tuning is important to produce efficient and lasting light emitting diodes ( led ) and other electronic devices
利用mg _ xzn _ （ 1 - x ） o薄膜，可以在保持zno六方纖鋅礦（ wurtzite ）結構的同時有效調節調節薄膜的禁帶寬度，制備出基於氧化鋅的量子阱、超晶格及相關的光電器件，如基於氧化鋅的紫外光探測器、紫外發光二極體和紫外激光二極體等光電子器件。
