In Two-Transistor Flyback Converter circuit, a power semiconductor device in Flyback Converting circuit has been replaced by two power semiconductor devices which parallel connected with an ultra-fast diode with soft recovery characteristics. Two-Transistor Flyback Converter can reduce greatly the switching stress of the power switch and does not need to degausser, suitable for high input voltage Switching Power Supply.

反激变换是从Buck-Boost变换演变而来的，将反激变换电路中的单个功率开关管用两个替代，并在每个功率开关管上并联一十箝啦的快恢复二极管而形成的双晶体管反激变换电路，能大大降低功率开关管承受的开关应力，且不需要消磁电路，非常适用于高输入电压的开关电源。

In addition, the algorithm has comprehensive potential application in computer graphics, computational geometry and so on. To fast and precisely select nodes and elements, some transformation functions which are implemented substitute the OpenGL's API functions, then facilitate dynamic interactive query.

为了精确、快速的选择节点和单元，作者通过对OpenGL拾取选择技术内部实现细节的深入分析，开发程序实现了一些变换函数，解决了OpenGL提供的API函数不能对节点单元的精确任意拾取的问题，并实现了节点单元的动态交互查询。

Taking advantage of gauge transformation and dipolar approximation, we qualitatively derive rotating Bose-Hubbard model.Then finite temperature phase boundary between superfluid phase and normal state in rotating Bose-Hubbard model is analytically derived by studying the stability of normal state in rotating bosonic optical lattice.We also analytically prove that as the function of rotation angular velocity the oscillation of critical hopping matrix directly follows the upper boundary of Hofstadter butterfly.

4通过做一个规范变换和偶极近似，定性地推导了旋转Bose-Hubbard模型，并且通过研究正常态不动点的稳定性推广了旋转Bose-Hubbard模型的零温相图到有限温度的情形；另外根据系统有效的能带宽度与旋转速度的关系(Hofstadter蝴蝶)，得到了系统的临界跃迁矩阵随旋转速度的改变展示谐振行为的结论。

Numerous types of inverter are available, but not all are suitable for use when feeding power back into the UK mains supply.

许多类型的变换器是通用的，但不是所有的适合使用，当能连回到英国的供应。

The horse should remain light and soft' on the bit' and be able to go smoothly from the passage to the piaffe and vice-versa, without apparent effort and without altering the cadence, the impulsion being always lively and pronounced.

马匹仍然轻柔地受衔\\，并且能流畅地从正步变换到原地踏步，又能相反地变换，变换动作不牵强，节奏也不变，始终有明显活跃的前进气势。

Next, the Bandelet transform is taken on each directional subband. The proposed multidirectional and multiscale transform with critical sampling can represent the geometrical features such as edges and texture more sparsely, which is of great benefit to image compression.

原始的Contourlet变换有大于1的冗余度而不适于图像压缩的要求，采用传统的张量积小波变换取代其中的拉普拉斯金字塔式变换可获得非冗余的变换形式[8]，Bandelet变换是一种基于图像边缘的变换方法，它能自适应地跟踪图像的几何正则方向。

At present, the ability of counteracting geometric attacks hasnt completely achieved the request of application.

目前数字水印算法的抗攻击能力还不能完全达到应用的要求，几何变换攻击被认为是提高水印算法鲁棒性的关键问题。

The traditional skeletonization algorithms based on distance transform can not guarantee the connectivity property, so saddle points should be added to solve the connectivity problem.

传统的基于距离变换的骨架算法不能保证骨架的连通性，需要引入鞍点解决连通问题。
