For canvases over 40", it is best to brace the back or corners, if not using heavy duty stretchers. A major brand for stretcher bars is Fredrix, and these are sold in art stores and some office supply stores. If you are handy with saws, you can make your own stretchers with wood from the lumber yard, a piece of curved molding, and a mitre saw. Me, I'd rather spend my time painting, so I buy pre-made stretchers. You also will need "keys for the stretchers, small wooden angled chips, which are used to make the stretched canvas more snug in the corners. These are free, and are usually found near the stretcher bars, in a box. You need 8 of them; just grab a small handful when you buy your stretcher bars.

Design of the Tension Measuring Mechanism for Wire Electrode;2. Based on electrochemical etching principle,the micrometer scale wire electrode was online fabricated,and the equipment of WEMM was established.

基于电化学原理，讨论了纳秒脉冲电流微细电解线切割加工的机理，建立了微细电解线切割加工数学模型；采用电化学腐蚀原理对微米尺度线电极进行在线制作，建立了微细电解线切割加工试验系统，并进行了微细电解线切割加工试验，切割出带90°直角的微结构，其切缝宽度为30μm。

Ceilings should be ac-cessible for cleaning, and ideally, the surface should he coved where ceilings and walls meet In many food-production areas, the ceiling must have thermal in-sulation This may be necessary either to prevent surface condensation or to reduce the energy costs of maintaining low environmental temperaturesWalls should also be insulated, to prevent surface condensation They should be free from rising damp and be protected, where appropriate, from damage by forklift trucks, by use of a guard rail In modern factories, there is always a coved surface where walls meet the floor It is also usual for there to be a coved surface where walls join at right angles.

天花板应该交cessible清洗、最理想他表面复岩下天花板和墙壁应满足许多粮食产区，天花要有热的绝缘要么这可能需要防止或者减少表面凝结能源维护成本低，对环境温度也应绝缘墙壁、应防止表面凝结他们免于受到保护和潮湿上涨，酌情从叉车损坏，用现代铁工厂门卫、凡事总有复岩面墙那里迎接地板也是平日没有可能凡参加面复岩墙成直角。

The vibration test is marked in different velocities to probe the effective way of the beam damping by changing the fixed type of the beam on two ends,setting up the curve beam with right angle to sustain the beam,and installing the rubber damper,so as to reduce the amplitude of the beam .
