可用时间

As if time is absolute and can be measured by a standard ruler.

的单位，好像时间是绝对的，可用相同的尺度来量度。

But the space is the matter, the matter is the string vibration, only has from this the time which vibrates f=1/T to draw out only then has the physics significance, therefore T is in the true significance time, from this deduction: What imaginary number Ict expresses is void, may write *ct,=I pure imaginary number, also is it with Number space Sigma (x1i*x2j)(i, j is subscript, i=j=1,2,3) differs 90 in the space, the shape for example: Psi ==a+Ib, constitutes a duplicate space by psi i* psi j,(definition mark * for ordinary multiplication) may use Four single numbers

而空间就是物质，物质就是弦的振动，只有从这个振动f=1/T引出的时间才有物理意义，所以T才是真正意义上的时间，由此推论：虚数Ict所表达的是一个虚空间，可以写成*ct，=I纯虚数，也即它与实空间Σ(x1i*x2j)(i，j为下标，i=j=1，2，3)在空间上相差90度，形如：ψ==a+Ib，由ψi*ψj构成一个复空间，可用四元数

The signals are amplified so that the time interval between them can be measured with a micro-second time interval measurement unit.

Sometimes, when I was pushed into an argument on left brain versus right brain, or nature versus nurture, 1 would instantly fight fiercely on my behalf and all womankind.

很可能，你会认为这样花去的时间要远多于你可用的时间，结果等到最后期限临近，你只能盯着草稿发呆。

Of course it is very discommodious. Based on previous studies of the application software to calculation on properties of smoke flow in fire Network Modeling and the time forecast software of personal evacuate travel in high-rise building, according to the quality and energy conservation principle, the paper proposes fire flue gas temperature when the fire reaching a dangerous state in the network model, then evacuation time can be calculated. Simultaneity, the paper proposes a new method that combining VB with MATLAB program technology to analyze and evaluate safety egress in Multi-layer and Multi-room building fire, besides the BF-SPES(the Building Fire Safety Performance Evaluation System)is worked out.

本文在重庆大学开发成功的火灾网络模型烟气流动预测软件和高层建筑人员疏散行动时间预测软件的基础上，根据质量和能量守恒原理，提出了火灾网络模型下火灾达到危险状态的烟气温度值，这样便能计算出可用安全疏散时间；同时提出了一种基于VB与MATLAB混合语言编程技术开发的多层多室建筑火灾安全疏散评估方法，并开发出建筑物火灾安全性能评价系统BF-SPES(the Building Fire Safety Performance Evaluation System)。

These tests show that: 1. suction decreases with the increase of the water saturation in the chalk; 2. stress variants proposed are available for describing the stress state of the unsaturated chalk; 3. preconsolidation pressure increases with suction, while the effects of suction on the compressibility coefficients λ and κ are not evident; 4. as usual unsaturated soils, the permeability to oil of chalk increases with the suction; 5. yield strength of the chalk behaves with volumetric strain hardening; 6. cohesive behaviour of the chalk is related to the stress level, and relation between time-dependent deformation and logt is linear; 7. cohesion of the chalk decreases with the increase of the suction, while the elastic stiffness and the cohesion coefficient increase; 8. strength and elastic modulus increase with the strain rate, while the strain at the peak strength decreases with the increase of the strain rate.

试验结果表明，白垩中的虹吸力随水饱和度的降低而提高；吸力、水饱和度和强度的变化过程均与时间有关；可用由理论分析得到的应力状态变量描述非饱和白垩的平衡状态；前期固结压力随吸力增加而提高，而压缩指数λ与κ则同吸力无关；应力大于前期固结压力时，粘性变形与时间的对数关系曲线呈线性关系，其大小和增长速率均随吸力减小而增大，可视为白垩弹性刚度降低和粘性系数增大的结果；前期固结压力和变形模量随着应变速率的提高而提高，压缩指数κ和λ则随应变速率的提高而减小；应变速率较低时，粘性和吸力对前期固结压力及压缩指数的影响较小；白垩中油的渗透性随着吸力增加而提高；白垩在屈服阶段具有明显的体积应变硬化特性。

For the coherence in metadata, a serverless architecture model based on all the data and metadata is adopted because they can be storaged in all place and can be dynamicly transferred; The associative mode of the disc metadata's journal structure and the memory metadata's journal structure can turn away the timing waste in scanning the enormous file system by fsck; Afterwards a intercalating checkpoint algorithm and a rollback recovery algorithm based on the metadata fault tolerance in cluster file system is implemented; A fetched stochastic process model is setup to analyze availability of this system, it can reduce the inspecting fault time and then they support high availability.

为了达到复杂的元数据管理一致性，采用了一个无集中式服务器的体系结构，保证所有的数据和元数据能够存放到系统的任意地方，并且在操作的过程中可以动态迁移；采用元数据的磁盘日志结构和内存日志结构相结合的方式对元数据进行管理，减少了fsck对庞大的文件系统中元数据的扫描时间；为了实现故障恢复，提出了元数据容错的设置检查点算法和回卷恢复的算法，提高了文件系统元数据服务的可用性；给出了基于元数据故障的随机过程模型，可以通过减少检错时间提高文件系统的可用度。

Solidify time: usually the cloud stone glue could use proper solidify agent to increase or shorten the solidify time, but for stone hooking structure glue, it can not do in this way.

由于施工人员的云石胶使用习惯会造成干挂胶的使用误区，比如用固化剂来调节固化时间，云石胶可用固化剂量的适当增减来调节固化时间，有些施工人员就会沿用到干挂胶使用上，靠加大固化剂投量，以达到快速固化的目的。

A safety level-based evacuation scheme of subway station is presented in this paper, with performance-based evacuation design combined. According to the evacuation characteristics of subway station, accidental evacuation time and available safety evacuation time under smoke control have been classified into three safety levels respectively. Then four safety levels have been proposed based on them. A flow chart of safety evacuation scheme of subway station under fire was then proposed based on the guidelines of safety evacuation and code for design of metro.

针对地铁车站人员疏散特点，以人员安全疏散准则和现行地铁设计规范为基础，融合了火灾安全工程学的性能化人员疏散设计思路，分别将事故疏散时间和烟控可用安全疏散时间划分为三个等级，综合形成了四类人员疏散安全等级标准，并在此基础上提出了框架性的基于安全等级的地铁车站火灾人员安全疏散方案设计流程。

Cooking time can be used as a guide to the degree of doneness, but cooking time is affected by fat and moisture content and shape or size of the cut.

烹调的时间也可用来指示烹调的程度，但烹调时间还受脂肪和含水量及肉块的形状和大小所影响。

I am sure after a few weeks of adaptation and familiarization I will have no difficulty in functioning on a daily basis in an English speaking society or in participating fully in graduate studies.

在大学的三年的学习生活不仅给予我自身的充实，更重要的是磨练和培养了我较强的自觉能力和严谨，踏实的作风以及不怕困难的精神，对未来充满了信心！

As the first volcanoes erupted, one of the gases that bellowed out was steam.

在第一批火山喷发时，喷出的气体之一就是水蒸汽。
