After 90 days, you need to call the company that manufactured the vacuum to fix it because its still under their warranty. 90天之后,您需要联系生产商来修理它,因为您购买的吸尘器还在厂商的保修期内。
If a vacuum is still not established, there is a blockage in the tool. 如果仍未形成真空,则表明工具中发生堵塞。
A vacuum UV electrodeless discharge lamp is designed. Even if he can start handing out loans, this finance trust of his is still nothing but a hoax! 本文介绍一种真空紫外无极放电灯.尽管他当真要放款,那托辣斯还是空炮!
Assuming the electronics are not suspect, if the plasma cleaner is run under vacuum but without the sample in the chamber, does the smoke still appear? 假如电子部件完好,假如开启清洗机及真空泵,而样本未放进舱内还有白烟出现吗?
Due to the fact that energy consumption of freeze-drying is much higher, so the combined microwave vacuum drying method is still a good method to produce high quality garlic slices. 但由于冷冻干燥能耗大,因此微波真空干燥与真空干燥联合干燥法仍是一种生产优质大蒜片的干燥方法。

4, some "vacuum belts" still exist. 还存在某些真空地带。
This paper Summerizes the embedded integrated passive PWB and their choice for non-vacuum processing and vacuum processing, and still discussion on business expanding trend of embedded integrated passive. 概述了埋入集成无源元件印制板以及它们的非真空加工和真空加工的选择,还讨论了埋入集成无源元件业务的拓展趋势。
The result shows, as a consequence of anisotropy of vacuum, though the two dipole matrix elements orthogonal to each other, quantum interference still exists. 结果表明,由于真空的各向异性,尽管原子的两电偶极矩阵元相互正交,量子干涉依然存在。
Vacuum membrane distillation is widely applied in seawater desalination, aqueous solution treatment, solution concentration, super pure water preparation and environmental conservation with its distinctive advantages. However, the studies on vacuum membrane distillation are still quite scarce. 真空膜蒸馏技术以其独特的优点在海水淡化、水溶液处理、溶液浓缩、超纯水的制备、环境保护等领域得到广泛的应用,但这方面的理论研究还较少。
When the quantum electromagnetic field be in its vacuum state, still its field quantities have the "vacuum fluctuation". 量子电磁场处在真空态时,它的场量仍然有“真空涨落”。
But some key issues such as the vacuum packaging process, vacuum retention, vacuum measurement have never been solved completely, especially the vacuum measurement in wafer level vacuum packaging still have no effective testing methods. 但真空封装工艺、真空保持性、内部真空度测试等关键问题一直未得到真正的解决,特别是圆片级真空封装的真空度检测至今没有有效的检测方法。
However, research on USM and its friction material ( FM) in vacuum and low temperature was still incomplete. 然而,真空低温下的超声马达及其摩擦材料研究仍不完善。
The researches on basic theory and engineering practice of vacuum sewer system of foreign countries are relative mature, but still not sufficient in china. 国外真空排水系统的理论研究和工程实践相对成熟,而国内关于对真空排水系统的基本理论、设计方法的研究并不充分。
