查询词典 fail-safe system

Both questions have troubled "two realm" philosophers—or dualists to give them their more usual name—, but the former has troubled them more, since modern physics is founded on principles that assert the conservation of various physical quantities. If a non-physical event causes a change in the physical world—dualists are repeatedly asked—, does that not imply that physical quantities like energy or momentum fail to be conserved in any physically closed causal system in which that change occurs?

所有这些问题困扰着二元论的哲学家，但是前一个问题更麻烦些，因为现代物理学坚持多种物理量的守恒原理，二元论者就会反复追问：如果一个非物理事件导致了物理世界的变化，那么，这不是就导出物理量不会守恒（而这是在物理上封闭的因果系统所会发生的）？

D models are the most widely spread in the world of turbo-machinery for its simplicity, but they are indeed purely empirical correlations which not only fail to provide detailed information inside one or more components, but also require significant effort to recreate themselves if engine operating conditions or component representations change; quasi 3-D models have been the workhorses for compressor and turbine design for many years, and the primary benefit of using quasi 3-D system models is to facilitate the design and detail analysis of a particular component across the range of possible boundary conditions; Full 3-D models are gradually replacing quasi 3-D ones by virtue of requiring no exit flow angle model and loss model and being capable of predicting secondary flow in cascade.

零维模型由于使用时简单易行，因此在涡轮发动机的仿真中得到广泛应用，但零维模型作为纯粹的经验关系式无法反映部件内部的流动细节，并且一旦部件有少许改动则新特性的建立耗费巨大；准三维模型由于能够详细地提供部件内部的流动情况，方便设计而成为涡轮和压气机设计的主要工具；全三维数学模型正逐步取代准三维模型在涡轮设计中的主导作用，同后者相比前者能够预测叶轮机械内的二次流动，在粘性流计算时不需要气流角和损失的经验公式，因此拥有巨大的发展前景。

At present the main product not damages the examination class instrument for the project scene: Thunder and lightning radiation monitor meter and multi- stations thunder and lightning monitor and positioning system, low tension cable fail monitor, cable fault position finder and so on.

目前主要产品为工程现场无损检测类仪器：雷电辐射监测仪和多站雷电监测与定位系统、低压电缆故障检测仪、电缆故障定位仪等。

Although there were many news stories touting the success of the system, it did fail to defend against several missiles, including one that killed 28 U.S. soldiers in Dhahran, Saudi Arabia.

尽管有很多新闻故事都在吹捧这个系统的成功，但是它确实失败的抵御几枚导弹包括一个在沙特阿拉伯的达兰牺牲28个美国战士的导弹。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
