The method includes the steps of gripping the peripheral edge of the fabric in a stretching assembly, activating the stretching assembly to stretch the fabric in a location adjacent to the mold assembly, clamping the stretched fabric against a face of the mold assembly, releasing the peripheral edge of the fabric from the stretching assembly, moving the stretching assembly from the path of the mold assembly, closing the mold assembly on the fabric with the peripheral edge of the fabric terminating in the mold cavity and injecting molten material into the mold cavity to form the frame directly on the peripheral edge of the fabric.

方法包括的步骤为在拉伸装置中夹紧纤维织物的外围边缘、在邻接浇模装置的位置启动拉伸装置来拉伸纤维织物、贴着浇模装置的面夹住已拉伸的纤维织物、从拉伸装置释放纤维织物的外围边缘、从浇模装置的轨迹移动拉伸装置、在纤维织物上闭合浇模装置并使同纤维织物的外围边缘终止在浇模空腔中和将熔化的材料注射到浇模空腔中以在纤维织物的外边缘直接形成框架。

During this process, a vacuum is generated in the chamber, and garnet abrasives and air are pulled into the chamber, through an abrasive feed tube, and mixes with this high speed stream of water.

此过程中，由于水射流的高速运动，在混合腔中产生了负压。在此负压作用下，从磨料罐输出的磨料与空气一起被吸入混合腔，并在水射流的加速作用下，经磨料喷嘴喷射出，形成磨料射流。

The author considers that the form of the instrumental music structure came from special opera shape in Shangdang area and its act with five tune-patterns together in the same platform, it is also due to the Shangdang phonic criterion in Yongzheng government of Qing dynasty, which objectively shaped its system and scale, and meanwhile accelerate its growth and creativity. Shangdang instrumental music absorbed broadly t...更多he instrumental music on experience of Kun opera, Luo opera, Juan opera and Huang opera on basis of instrumental music on the local tune, which contains with diversity, and generally became of the art matrix of Shangdang folk music and opera melody.

本文认为：上党梆子器乐结构的形成，主要来自上党地区独特的戏曲生态和五种声腔同台共演的历史经验；特别是清代雍正年间国家政策对上党八音的规范，客观上引发了上党梆子器乐在体制和规模上的定型，也促进了上党梆子器乐在此基础上不断发展、创新；上党梆子器乐是在梆子腔器乐结构基础上，广泛吸收了昆腔、罗腔、卷腔、簧腔在器乐结构中的经验，由此兼容并包，逐渐成为集上党民间音乐和戏曲音乐大成的音乐艺术母体。

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。
