In working, the tube via tube hoop is connected to the upper bottom plate (2); the lower bottom plate (3) is fixed to the groundsill; when the tube is vibrated, the distortion of spring can damp and adsorb the three-dimensional vibration of tube. The invention has lower natural frequency and wider temperature application, with simple structure and easy maintenance.

工作时，需减振的管道通过管箍与本发明所述的三维减振器的上底板(2)固接，三维减振器的下底板(3)与地基固接，当管道产生振动时，通过弹簧的变形来减小和吸收管道的三维振动，达到减振的目的，它具有较低的固有频率和较大的使用温度范围，具有结构简单可靠、安装方便、维护简便的优点。

Because the carbonyl in its structure is with strongly absorb-electron effect, so it is a kind of non-proton polarity solvent with high boiling point, high flash point and low melting point, use conveniently for many processing operation such as filtration, distillation, solvent extraction, and so on; it is with very low toxicity, so the harm to human body is inappreciable, and reduce the environment pollution; due to its very strong dissolvability, it can dissolve organic matter, inorganic matter, resin, polymer, etc., and activate all kinds of reagent, mix to dissolve the other high boiling point solvents; it is with very good stability, it is stable under the hot strong alkali and acidity condition, it is with water-resistance and light, oxygen stability.

246℃ m.p：—20℃闪点121℃ flash point： 121℃分子式：C6H12N2O molecular formula： C6H12N2O 分子量128.18 molecular weight： 128.18 二、DMPU的化学性质 Chemical character of DMPU 其结构中由于羰基具有强烈的吸电子效应，因而它是一种非质子的极性溶剂，具有高沸点、高闪点、低熔点，在过滤、蒸馏、溶剂萃取等工艺操作中使用方便；毒性极低，对人体危害微不足道，也减少了对环境的污染；由于它具有极强的溶解性，能溶解有机物、无机物、树脂、聚合物等，并对各种试剂具有活化性质，还能与其它高沸点溶剂混溶；具有极好的稳定性，在热的强碱和酸性条件下都很稳定，还具有耐水性及对光、氧的稳定性。

It is more conservative with screen handling and thus does not screw up the screen as easily as more or less. p uses its own termcap package with TERMPATH support that makes it easy to have a local .termcap file in the user's home directory to override bad termcap entries. p supports three text attributes for nroff: bold, italic, and bold-italic. p is able to find patterns in higlighted text. p also filters out unprintable characters.

它在屏幕处理上是更保守的，这样就不会轻易地把屏幕弄得一团糟。p使用它自己的带有TERMPATH支持的termcap包，这可以方便地用用户主目录中的本地。termcap文件覆盖坏的termcap条目。p支持nroff的三个文本属性：粗体、斜体、和粗-斜体。p能在突出选中的文本中发现图案，也可以过滤出非打印字符。

Where a lot of other machines might have ports and protrusions along their edges, the Air has none -- it swoops inward from the edge to the base with only two spots for plugs, a new, 90-degree angled MagSafe power connector on the left underside, and a clicky, extremely sturdy-feeling foldable door that is impossible to open while resting on the table, and basically requires picking the entire machine up.

尽管大部分的手提电脑在两侧都会有接口和插槽(原文为protrusions，意为隆起的部分，此处应该理解为插槽—译者注)，可是MBA却有别于寻常的机子—它的所有接口都是隐藏在一个可以90度翻开的折叠门里，这个折叠门和充电器的磁吸口都在MBA两边的下方。这个可翻开折合的门让MBA用户可以在使用MBA的时候连接其他的设备，也可以在需要的时候方便的把MBA放进袋子里而不损坏到接口。

In this paper, by considering the convenience of consumers, we use group blind signature technology with the character of hash chain to create the dividable and anonymous e-cash. Thus the users can consume not only in the home mobile domain but also visit mobile domain without register and authentic. We use off-line e-cash to increase the efficiency of payment exchange. Under the fair principle of all participators, we set a convenient and secure mobile payment.

因此，以消费者使用上的最大便利性为考量，本研究利用群体盲签章加入杂凑链之特性的方式来产生可分割的匿名电子现金，让消费者不只可以在主系统业者的网域内作消费，当其到漫游业者的网域内消费时，也不需要额外的认证及注册过程，并采用离线验证的方式来增加付款交易的效率性，在考虑各角色公平的原则下，提供一个方便、安全的行动付款系统。

The merits of this approach include: Increase the efficiency of parting line determination algorithm by effectively excluding the faces irrelated with parting line determination; Be able to identify internal parting lines by utilization of molding features; Employ a proper objective function to determine the optimal parting line.

该方法的特点在于基于注塑的特征模型有效地排除了所有与确定分型线无关的塑件组成面，提高了算法的效率；通过注塑特征的使用，能够方便地确定内分型线；利用一种合理的分型线评价方法，确定优选的塑件分型线。

And the scientific research showed that they are medicable to insomnia, anxiety and other diseases that found in modern people. 4 The regression models of biomass were used to calculate the total cumulative biomass. Average biomass of six samples was 62.88 t·hm-2 after cutting 3 years, which was higher than that of tropical secondary forests with 5 years succession. It can be concluded that traditional fuel woods had played an important role in conservation of tropical forest in the area. Caloric values were not different in major fuel species (Coefficient of variation was only 1.1%). The similar result was found in stems of C. siamea after growing different years. The main reason of C. siamea cultivation was that it had the character of hardwood, easy collecting, little ash, and so on.

铁刀木的各个部位都作药用，资源量大的树叶和心材使用最多，并且现有的研究成果表明它们具有多种活性成分，针对现代人常患的失眠、焦虑等疾病具有较好疗效。4）通过收获法拟合的生物量回归模型对推测西双版纳地区铁刀木林薪柴蓄积量有较高的参考价值，砍伐3年后的六个样方中铁刀木的平均生物量为62.878 t.hm-2，高于5年林龄的热带次生林（16.35t·hm-2），对西双版纳热带雨林的保护有着重要意义。5）几个村寨最主要的薪材树种热值研究结果变异系数仅为1.1％，各薪材树种之间热值相差不大，铁刀木被选择为传统薪炭林更多是因为材质坚硬、收获运输方便、燃烧完全等特点。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
