This project is intended to modify circular disk loaded in diametral compression method, from concentric load to distributed load on a small area to reduce error. Firstly, we will establish digital Photoelasticity system, manufacture specimen, design loading frame, and then the experiment will completed.

本计画主要目的在减少误差而修正圆盘试片受上下压力实验法的数学理论依据，负载从集中力改为有限范围的均布力，经过理论推导后，以自行组合之数位光弹仪实验比较两者求出的材料条纹系数值。

The fracture toughness testing technique for the central cracked circular disk specimen is given to investigate the fracture behavior of brittle material polymethyl methacrylate under pure mode Ⅰ, pure mode Ⅱ and mixed-mode loadings. The experimental results show that the load distribution angle is always greater than 8° for all different loading conditions.

The following are the expressionsfor the mean pressure set up at the detection plate and for the time of the signal toprogagate from the radiator to the detector:这里是1个公式,省略） where Re is the real part of the expression appearing within the braces, 0 is the density ofthe medium, vo is the amplitude of the vibrational velocity, c is the speed of sound in themedium, d2 = I +(r/zcos 8, z is the distance between the emitting and receiving plates, B is the angle between the axis of the acoustic channel andthe axis of the tube, r = vro/c, v is the flow speed of the fluid, d is thediameter of the pipe, m is the circular frequency, k is the wave number,where a is the radius of the plate (this is taken as the same for the emitting and receivingplates for simplicity, but there is no difficulty in discussing plates differ~mg in radii),,~ is the vibrational frequency of the emitting plate, andThe triple sums in the expressions for N~ and N2 may be neglected if the flow speed islow, since the contributions for these become negligible.

以下是表达式平均压力为定于检测板和为信号时间progagate从散热器到探测器：（这里是1个公式，省略）假如再是出现在大括号表达式的实部，0是密度中期，沃是速度的振动幅度，C是健全的速度中，D2中=我+的导向8，z是对之间的距离发射与接收板，B是声之间的通道轴角该管的轴，R =中心内大多分为/荤，v是流体的流动速度，，D是管道直径，m是圆频率，k是波数，的其中一盘是半径（这是为重点，同样的发射与接收为le简单板，但没有讨论板的困难，在半径不同毫克），，是发光板振动频率，和在N的表达式的三重总结和N2可以忽略，如果流速低，因为这些变得微不足道的贡献。

The species of cladoceran and copepod in Shiquan River are fewer. From the specimens we observed 5 families 8 genus 18 species of cladoceran and the dominant species are A. sp and Chydrorus sp. Copepoda had 2 orders 8 species.

狮泉河的枝角类和桡足类种类很少，所采样品仅检出枝角类5科8属18种，优势种类为尖额溞和盘肠溞；桡足类2目8种。

Discharge hole to end head about 40cm, screw of Openings and valves adopt stainless steel screw screws, single coaming board on the top of tank ,and make SBS asphalt anti corrosion on the top.

三个进料口，钢衬罐盖带接酸盘，其中中间为加大人孔盖，2个呼吸阀，后底部左右各一个DN80的放料阀，，出料口距离后封头40公分左右，罐口及阀门螺丝均采用不锈钢螺丝。罐顶做单围板，顶部做SBS沥青防腐。

Place fruit in a pedestal bowl or mixed nuts in a compote dish for a new look.

将水果置于有底座的碗里，或将混合的各种坚果放在一个果盘里，呈现出一番新的景象。

A new high flow rate,multichannel parallel plate denuder sampling system has been developed which is capable of determining the particle size distributions and the semi-volatile organic compounds which can be lost from particles during sampling.

已研制出一种新的高流速率，多通道平行盘溶蚀器取样系统，它能确定微粒大小的分布，以及在取样期间从微位失去的具有半挥发性的有机混合物。

We present 4 cases of symptomatic discoid medial meniscus.

这里我们给出了4例具有症状的内侧盘状半月板病例。

If the disk is infected with the virus, the memory is read the first part of the virus program, it has been modified after the control of the size of memory space available in high-end memory think of a region, and moved to the first part of the area, and then read on the disk "bad cluster" in the second part of the first part and to put together, so that all proceedings on the presence of the virus in memory of the high-end, and then modify the interrupt vector INT13H or other interrupt vector to the high-end virus program, then you can read the original boot memory and the control over to it to complete the system startup.

如果是染上病毒的盘，读到内存的是病毒程序的第一部分，它得到控制权后修改内存可用空间的大小，在内存高端辟出一块区域，并把第一部分移至该区，接着读入放在磁盘"坏簇"中的第二部分，并和第一部分拼起来，使病毒程序全部驻留在内存的高端，然后修改INT13H的中断向量或其它中断向量，使其向高端的病毒程序，这时即可把原引导程序读到内存中，并把控制权交给它以完成系统的启动。

This weekend, we put about twice the size of disk capacity.

这个周末，我们的放盘量一下多出一倍。
