The converter can be improved just by exchanging the position of the resonant inductance and the transformer such that the transformer is connected with the lagging leg. The improved converter has several advantages over its counterpart, e.g., the clamping diodes conduct only once in a switching period, and the resonant inductance current is smaller in zero state, leading to a higher efficiency and reduced duty cycle loss. The operation principle of the improved converter and the comparison with the original converter are analyzed in this paper. The effect of the blocking capacitor in series with the transformer or resonant inductance is discussed, and a best scheme is determined.The improved converter is adopted to design the DC/DC converter of secondary power supply in HVDC power system.

本文将谐振电感和变压器交换位置，使变压器与滞后桥臂相连，这样箝位二极管在一个开关周期中只导通一次，同时零状态时谐振电感电流较小，有利于提高变换效率和减小占空比丢失，本文分析改进后变换器的工作原理，并与改进前的变换器进行对比，讨论隔直电容在不同位置对变换器工作的影响，确定一种最佳工程方案。

Anily, Hornik, and Israeli (1999) estimate that the average homeowner will live in their current residence for 13 years, while Bogle (1999) estimates that the average mutual fund investor has a holding period of around one year.

Anily，Hornik，以色列(1999)估计平均房主将生活在他们当前的官邸多年，虽然宝格先生(1999)估计，平均共同基金投资者一个持有期间大约一年。

So far, it is not very clear why the delayed postarc restrikes occur. In this thesis, two kinds of restrikes have been discovered through prebreakdown current measurment and analyses,(1) the abrupt breakdown, it is characterized by a suddenly appeared, with a period of a few microsecond prebreakdown current, it is initiated by particle. This kind of restrikes can be reduced by decreasing loosly adhesive clumps which drop into the gap after arc extinction.

弧后延时重击穿的起因尚不清楚，本文通过对预击穿电流的测试和分析，发现这种重击穿主要有两种类型：（1）突发性的击穿类型，其特征是击穿前看不到预击穿电流的增长过程，预击穿电流的形成只有数微秒时间，这种击穿是由颗粒引起的，减少大颗粒脱落可以降低这种击穿的几率。

Using the method of current heating in the course of creep, there are many excellences as following: Complexity of creep test device can be minished. Labor intension is weakening, speed of heating is easy to control. Period of test is reduced. Current heating method is economic than traditional heating method about 59%.

蠕变试验过程中采用电流加热的方式，不仅降低了试验设备的结构复杂性和劳动强度，而且加热速度容易控制，热能利用率高，大大缩短试验周期，较电炉加热方式节省能量消耗约为59％，具有很高的经济价值。

Based on the data analysis and numerical simulation, the Arctic sea ice climate variability was researched, the result were as following:(1) The analysis on the seasonal cycle of the Arctic Ocean and atmosphere showed that: The seasonal surface wind is somewhat trade wind like in some regions in the Arctic. The surface air temperature is robustly determined from the underlying environments such as sea ice and Greenland glaciers. In the sea ice region the precipitation rate is larger than that of evaporation. Furthermore, the Arctic Ocean hydrology is profoundly influenced by the surrounding rivers discharge. These are the decisive factors on the ocean salinity pattern. Sea ice flux through the Fram Strait is larger in winter than in summer. From the 40s in the 20th century on, the ice volume flux has an increasing trend. The Arctic rivers flood season is about the melt period, the winter rivers discharge has a significant increasing. Correlation analysis shows that 7 to 10 years is a characteristic time scale that rivers discharge leads Fram Strait ice volume export.(2) Considering 9 major arctic rivers, the Arctic Ocean circulation was simulated through BOM. The result shows that: The BOM can reproduce the main Arctic Ocean circulation pattern. The"Islandization"which is commonly used in OGCMs to treat the North Pole, not only influences the ocean current near the pole, but also influences the current in the Northern Atlantic Ocean, thus the bogus island might influence global climate through thermohaline circulation in the Atlantic Ocean.

在资料分析和数值模拟的基础上，对北极海冰的气候变率进行了深入的研究，结果如下：(1)对北极地区大气和海洋季节循环特征的分析表明，气候平均风场在部分地区具有&信风&的性质；而气温场与海冰分布及格陵兰半岛冰原的下垫面特征有密切关系；在北极海冰区的降水量大于蒸发量，并且在全球大洋中北冰洋受到河流径流的影响最大，对北冰洋的盐度分布有决定作用；通过弗瑞姆海峡的海冰通量在冬半年大于夏半年，并且从20世纪40年代起，海冰的体积输送有增加趋势；北极河流的汛期主要在融化季节，冬季的河流流量有显著增加的趋势；相关分析表明7到10年是北极河流流量影响弗瑞姆海峡海冰体积输送的一个特征时间尺度；(2)采用BOM海洋模式对北冰洋海洋环流进行了模拟研究，在模式中考虑了北极9条主要河流的作用，结果表明该海洋模式可以较好模拟出北冰洋海洋环流的基本特征；多数大洋环流模式采用&北极岛化&的方法处理北极点，模拟结果表明&北极岛化&不仅影响到极点附近的海流，还会对相对较远的北大西洋海流造成影响，并可能通过大西洋的热盐环流对全球气候产生影响；(3)采用CSIM4海冰模式对北极海冰的气候态进行了模拟。
