The research indicated that high precision micro-gear can be batch achieved by silicone mould vacuum casting and the vacuum deaerating time had the most important influence on the physical dimension of micro-gear.

研究结果表明，利用硅胶模进行微齿轮真空铸型可批量获得精度较高的成形件，真空脱泡时间对微齿轮成形件的外形尺寸影响最大。

It is shown that when the Casimir force of M-C-S gauge field is calculated, the ghost contribution to the vacuum energy must be taken into consideration in U (1) covariant gauge theory, although the ghost decouples from the gauge.

这表明，即使在U（1）情况下，鬼场与规范场无耦合，在讨论真空的零点能时，鬼场的贡献是必须计入的。只有这样才能抵消非物理分量对真空能量的贡献，获得正确的结果。

Resin was degassed using a vacuum and the winding carried out under vacuum .

树脂用真空脱气，并在真空下进行缠绕。

Provides the theoretical data for the vacuum degassing purification and vacuum dry of liquid medium.

为液体介质的真空脱气净化和真空干燥提供了理论数据。

CNTs/PTFE and CNTs/epoxy composite materials were used as field-emission cathode and the two electrode configurations were encapsuled into a static vacuum system respectively.

通过对比测试，研究了两种复合材料阴极在静态真空系统中的场发射特性，比较了两者在不同场发射电流密度时的电流稳定性，以及随着封装后时间的增长对静态真空系统场发射性能的影响。

VS-600 external –pump vacuum machine Uses Japan and Korea leading technology collection vacuum,Seal,Gasifies the many kinds of functions in a body, The sealer uses the barometric pressure type, Thorough change tradition packing sealer not firm phenomenon.

vs-600 外抽式真空包装机采用日韩领先技术集真空，封口，充气多种功能于一体，封口采用气压式，彻底改变传统包装封口不牢的现象。

We have a long history in designing and manufacturing vaccum parts and accessories, high vaccum equipment, small type ball griding machine, 3D raw material mixer.

我们是台湾的领导厂商，已有12年以上的经验在设计生产真空零配件，高真空腔体设备，小型球磨机及3D动态混合机。

The results show that after quenched and tempered with protective coating,no elements in the protective coating are found to permeate into the matrix,but the martensite laths in welded zone and heat affected zone are refined and the dispersion of carbides in these area is increased,the sizes of the dimples in these fracture are decreased.

通常情况下，D406A钢壳体在热处理中未采用保护气氛，造成调质后壳体表面脱碳严重，使壳体强度降低。为防止或减少调质处理过程脱碳带来的不利影响，可采用保护涂料或保护气氛热处理以及真空热处理等[2]，但对于大型工件，采用保护气氛或真空热处理需要大量的设备资金投入；而采用保护涂料投入较少。

Further, the prior coating methods for shielding electromagnetic wave of electronic equipments include three kinds of methods including 1 a vacuum metalizing wherein the metal is vaporized and deposited on the material surface under vacuum; 2 a conductive paint spray wherein the solution containing

此外，先前的对电子设备进行电磁波屏蔽的涂层方法有三种方法，包括1）真空金属镀层，这里，金属在真空下被蒸发并沉积在材料表面；2）导电涂料喷溅，这里，含金属粉末的溶液被喷雾到材料表面；3）化学镀，这里，待涂覆的

No vacuum metalizing.

Fred：不，我们利用了真实的电镀制程，没有真空金属化，那会更难穿且真空金属化的问题是容易碎裂又太薄，这里有一张我们电镀完成的C-3PO，我想影迷们会喜欢的。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
