Using series of vector magnetograms and proper motions, we have analyzed a delta spot in NOAA 9077. This delta spot formed and disintegrated in a very special way. Its current helicity evolution has a close relationship to the magnetic configuration. We find the conclusion, for the first time, that the sign reversal of the helicity can lead to the disintegration of the compact delta structure.

There is no ferromagnetic material in the outside of ironless PM motors airgap. Because of this characteristic, airgap magnetic field of ironless PM motor belongs to 3-dimentions (3-D) open boundary magnetic field. Engineering problem of open boundary magnetic field is a hot research issue in the computation electromagnetics field recently.

无铁心永磁电机气隙外没有铁磁材料，其自身的结构特点决定了无铁心永磁电机的气隙磁场属于三维开域磁场，开域磁场工程问题的计算是近年来计算电磁学的研究热点之一。

I used the homemade ECDL to measure the 2S-3D two photon transition spectrum of Helium , the advantages are that the expense of homemade ECDL is cheap and have good output power. At the same time, I used the electronic part can be got in the market to manufacture a pulse generator in the experiment, the pulse generator can control the output frequency, the pulse width, the relative phase and also can simultaneously control four sets of systems or instruments need the TTL pulse control. The advantage is that the cost of the pulse generator is cheap and the pulse generator is stable. To isolate the magnetic field I used the magnetic foil to helium cell. I also built a gas discharge system, the switch sequence of this system can be controlled by the pulse generator. Finally I built a detecting system can measure the helium energy state. It is cheap and can be combined with the comb laser system in my laboratory.

本实验是利用一台自制的外腔雷射系统来量测2S-3D的氦原子双光子跃迁，其优点在於自制的外腔雷射之费用非常便宜，也有不错的输出功率，同时在实验中我利用市售的电子零件制作了一台脉冲产生器，可控制输出的频率、脉冲宽度以及相对的相位，且可同时控制四套需要TTL脉冲控制的系统或仪器，优点除了便宜之外，也非常稳定；为了隔绝磁场，利用了磁场隔绝金属箔，我也在实验室中建立了一组气体放电系统，其系统可以用脉冲产生器来控制开关时序，最后，我建造了一个氦原子能阶的量测系统，而且费用低廉，可与本实验室的另外一门研究光梳雷射系统做结合。
