真空

Medical Jurisprudence, as a branch of discipline, is still in the swaddle, therefore, there are many unsettled theoritical problems and challenges. It needs us work long and hard for its outline-making, meaning-making and characteristics-making. There are many vacuum zones in its priciples, theories and application.

医学法学作为学科尚在襁褓中，还存遗太多的理论问题和质疑，其学科附形、附义和附质的艰苦工作还需要我们长久地探索，其原理、原论、原用存在很多理论真空。

Using vacuum, the system then conveys adhesive in the shape of pellets, pastilles and mini-slats from the supplied adhesive storage container to the melter tank.

利用真空，然后系统传达胶粘剂形状的颗粒， pastilles和迷你缝从供应胶粘剂储藏容器的melter坦克。

The detailed procedures of the method are as follows: the charging material of Ti-6Al-4V alloy is put into the crucible of an induction skull melter, heated and melted under the environment of high-purity argon and 400-700Pa pressure; pre-coated bars with the TiH2 of the weight accounting for 0.09 to 0.2 percent of the charging material are added in; when the hydrogen-contained titanium alloy in the crucible cools and the temperature drops below 300 DEG C, the charging material is vented off and cooled until the temperature equal to room temperature.

它的具体方法为：将Ti-6Al-4V合金的炉料装入感应凝壳熔炼炉的坩埚中，在压力为400～700Pa的高纯氩气环境中进行加热熔化；然后熔入含炉料质量0.09％～0.2％的TiH2的预制棒；当坩埚中含氢的钛合金逐渐冷却凝固并降温至300℃以下后，破真空，进一步冷却至室温。

The machine-group is a new generation product on the base of introduction of the advantages of the foreign counterparts,integrating multiple-distillation,vacuum concentration and menstruum recycle,simplifying the operation procedure.

本机组是我厂在借鉴国内外同类产品的基础上研究开发的新产品，它集多功能提取、真空浓缩与溶剂回收为一体，简化了操作程序。同时由于整个提取浓缩与回收是在封闭的流体中进行。

So tomorrow I'll vacuum form the deck and the hull and if all goes well I'll be sending them out to Adam, BigDave and Merriman.

因此，明天我将真空，形成甲板和船体及如果一切顺利我会派他们到亚当， bigdave和梅里曼。

Metallurgist has focused the study on improving RH refining efficiency, product quality and broadening treating function.

在众多的钢水精炼工艺中，RH真空精炼工艺与现代快节奏钢铁生产过程相匹配，受到冶金工作者的青睐。

It is suitable for drying heat sensitive raw materials that can decompose and polymerize and metamorphose at high temperature. it is wide used in pharmaceutical, chemical, foodstuff and electronic industries.

YZG/FZG系列真空干燥机适用于在高温下易分解，聚合和变质的热敏性物料的低温干燥；被广泛地采用在制药、化工、食品、电子等行业。

The developments of vacuum metrology in China during the past 50 years are reviewed.

回顾了近50 多年来中国真空计量的发展历史。

The results showed the specimens by vacuum sintering had a typical Widmannstatten microstructure, which possessed coarser prior β-grains and secondary platelet α+β-phase, but the alloy had a more microporosity and a lower tensile strength and ductility. After HIP treatment, prior β-grains and secondary platelet α+β-phase became fine and uniform, and the alloy possessed a less microporosity and a higher tensile strength and ductility.

结果表明：真空烧结Ti-6Al-4V合金具有典型的魏氏体组织，其初始的β晶粒粗大，β晶粒内为次生片状α和薄β相片，空隙较多，合金的强度和塑性较低；合金经热等静压处理后，组织明显细化且均匀，空隙很少或几乎没有，从而强度和塑性都有所提高。

Simultaneously, It is found that modeling and simulation is the effective method understanding microscopic process of vacuum arc.

同时，可以发现，建模与仿真是理解真空电弧微观过程的一种有效方法。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
