查询词典 critical path analysis

In order to reduce the conflict of L1P in CMT,we propose the policy of logic partition L1P Cache by n power of 2 and the competing loop lock.Now the fairness researchs always need single thread sample phase,we propose a novel fairness policy:FROCM,it doesn\'t need single thread sample phase.We propose ring cooperant L1 data Cache,which can reduce both the complexity of the design and the load of L2 Cache.We also propose a method to exchange threads dynamicly based on fast-shared data pool,it can detect the data consanguinity of two threads in real time and exchange them into one core rapidly.At last,we design and implement a dual-core and dual-thread VLIW prototype YHFT DSP/DS based on the above studies.In order to enhance the bandwidth of data path and reduce the delay of critical path delay of CMT processor,we design a 10R/6W register file full customly.

为了减小多线程运行时指令Cache的冲突，本文提出了二幂等分指令Cache策略和循环锁竞争机制；现有对CMT处理器公平性的研究常常需要中断其它线程进行单线程采样，针对这个问题本文提出了多线程公平性策略FROCM；本文提出了环形协同数据Cache结构，以解决CMT处理器中共享存储体负载重，冲突大的问题；本文还提出了基于快速共享数据缓冲池的线程动态交换技术；最后本文实现了一个双核同时多线程芯片原型YHFT DSP/DS。

By using the basic theory of PERT/CPM, a programming model of the critical quality chain evaluation in manufacture process network is proposed; the path in which quality loss is maximal is the critical quality chain.

进一步应用PERT/CPM的基本思想，建立了生产制造过程网络关键质量链的规划模型，将质量损失最大的路径视为关键质量链。

The results show that single structure parameters (width and depth of flow path/passage, and height, and angle of dentations) are local and difficult to represent the anti-clogging ability of emitters. Characteristic structure parameters(minimum size of cross section, hydraulic radius and dentitions spacing) can represent the anti-clogging ability of emitters in a sense. There are anti-clogging critical values under the test. Rated flow Qr and the ratio of diameter of labyrinth passage to diameter of particle η are well cor related to the anti-clogging ability and have anti-clogging critical values too.

结果表明：用单一结构参数(流道宽度 W 、流道深度 D 、齿高度 h 和齿角度θ)表征其抗堵塞性能存在局限性；结构特征参数断面最小尺寸 min(D，W、水力半径 R 和齿间距 l 能较好反映滴头流道横、纵断面的结构特征，在不同程度上表征了流道的抗堵塞性能，且在试验条件下各自均存在抗堵塞临界值；滴头额定流量 Qr 和迷宫滴头径粒比η与抗堵塞性能相关性较好，且存在抗堵塞临界值。

Critical angle of refraction - semi-circular cylindrical mobile light source, the incident angle change the size of refraction angle to change at this time, when the refraction angle = 90 degrees, which is critical at this time angle of incidence angle, the critical angle of water at 40 degrees large about anything mobile source of water in the water screen that is a reflection of light, a phenomenon that total reflection.

光折射的临界角定义：光折射角=90度时，入射角即为临界角，按二方法，将半导体激光光源去掉铁夹，吸附在右下角的铁板上入射光对准中心，即产生折射光线，沿半圆形柱面移动光源，改变入射角的大小，这时折射角也改变，当折射角=90度时，这时入射角即为临界角，水的临界角大的在40度左右，再做移动光源在水中的水屏即出现反射光线，这种现象称全反射。

The unsaturated and compacted soil triaxial test result under constant suction describes the unsaturated soil critical state surface in p-q-s three dimensional space: in p - q plane, the slope M of critical state line is independent of suction; the cross line of LC yield surface and critical state surface is a curve with extremum in three dimensional stress space, and its projection in p-s plane is located in quadrant 1 in triaxial compression state; its projection in q-s plane has asymptote, and there should also be asymptote in respect of the curve that stands for the function relationship between cohesive and suction.

The coexistence curves and light scattering data for a critical solution of benzonitrile + octane have been reported. The critical exponents relating to the difference in the density variables between two coexisting phasesβ, the osmotic compressibilityγ, and the correlation length v have been deduced and the values were consistent with the 3D-Ising value in the range close to the critical point. The experimental results of the coexistence curves have also been analyzed to examine the Wegner correction terms and the behavior of the diameter of the coexistence curves.

In common glass fiber reinforced polyolefine pipe, when the volume faraction is less than the critical value, the glass fiber can not act as reinforcement, on the contray, it would reduce the whole intensity of the compound material. However, when extruded in combined stress field, the extend intensity of the compound system increases when the volume fraction of glass fibers is less than the critical value. When the glass fiber volume fraction is higher than the critical value, the required glass fiber volume fraction of compound fibers extruded in the combined stress field is less than theory value.

一般玻璃纤维增强管材在常规挤出时当添加的玻璃纤维体积含量小于临界体积分数(当添加的玻纤的复合体系拉伸强度等于基体聚合物材料的拉伸强度时的玻纤体积分数)时，玻纤起不到增强的作用，反而会使复合材料的整体强度降低；但在复合应力场下挤出时，当添加的玻纤含量小于临界体积分数时，复合体系的拉伸强度不但没有降低反而升高了；当添加的玻纤含量大于临界体积分数时，复合体系要达到同样强度，经过复合应力场的玻纤增强管材需要的体积分数小于理论值。
