工作介质

However, the dielectric fluid in the gap is ionized under pulsed application of DC, thus enabling the spark discharge to pass between the tool and the work.

然而，差距是离子液体介质直流脉冲下的应用，从而使火花放电之间传递的工具和工作。

The advantage of these models is that volume-averaging approximations are avoided at the scale of the fracture network.

本文的主要工作是致力于发展具有工程应用能力的非连续介质数值模型。

And our work is to synthesize the expandable graphite which has greater volume and lower sulfur content, with organic regent substituting for oil of vitriol and with some oxidants using to meet the need of the industry manufacture, to study the catalysis capability of the product.

我们的工作是改用有机介质逐步替换浓硫酸，在某些氧化剂的作用下制备出大膨胀体积，低硫含量的可膨胀石墨产品，使其符合工业生产需要，并对其催化性能进行初步研究。

The purpose of the studyis to control the process of materials surface modification promptly.

工作的结果对常压介质阻挡放电及其在材料改性上的应用具有重要的意义。

The use of mechanical seals, and do not have to fill, automatic mind, long life, wide parameters (pressure 15-30 kg / cm 2, temperature -50 ℃-450 ℃, to speed 0-500 /, media: conducting oil, steam , Water, air, etc.), is to address run, run, drip, leak, energy conservation, improve the working environment ideal for sealing components conducting oil rotating series of joint: in-house and the spherical shell after fine grinding process, using a spring 30WACr2VA tungsten chromium Vanadium alloy spring steel from refined, and the introduction of Japanese cedar trees machinery will be silver-impregnated graphite high temperature seals from the assembly, with the temperature effects, and life than the original, high-temperature range of 30%.

该产品采用机械密封，不必填料，自动同心，使用寿命长，参数广（压力15-30㎏/㎝2，温度-50℃—450℃，转速0—500转/分，介质：导热油、蒸汽、水、空气等），是解决跑、冒、滴、漏，节约能源，改善工作环境的理想密封部件（导热油系列旋转接头：壳体内部和球面经过精磨加工，弹簧采用30WACr2VA 钨铬钒合金弹簧钢精制而成，并引进日本柏木机械株式会银浸渍石墨高温密封件组装而成，具有耐高温之特效，而且使用寿命较原来中、低温系列高30％。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
