Divide the sample into the experiment group and control group, every group is every 60 people, the time of experiment is four months, test the height , weight before and after the experiment , the upper arm was enclosed , the bust , waistline , buttocks , thigh enclosed every body shape index , calculate BMI , WHR two indexes .

将样本分为实验组和对照组，每组各60人，实验时间为四个月，实验前后均测试身高、体重、上臂围、胸围、腰围、臀围、大腿围各项身体形态指标，并计算BMI、WHR两项指标。

Two of our wheels are driven by rotating power system to made the cylinder rotate . The swinging rack is driven by a set of crankshaft swinging bar which is mounted on the frame and the swinging rack is supported on the frame.

在四个支撑滚轮中，其中两个传动轮由转动动力系统拖动使转筒产生转动；摆动架由一组曲柄摆杆机构来驱动，曲柄摆杆机构装在机架上，摆动架由轴承组件支撑在机架上。

Continuation--Optimization method is proposed for approximate synthesis of linkages The synthesis of planar four-bar and six-bar linkages are studied using this method and several solutions are obtained. Thus, selection of the optimum solution for approximate synthesis of linkages is realized.

提出了机构近似综合的连续---优化法，并应用该方法研究了平面铰链四杆及六杆机构的函数综合，得到了多组机构尺寸方案，实现了机构近似综合的多方案优选。

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。
