电路 2 电路或电网络由以某种方式连接的电阻器,电感器和电容器等元件组成。如果网络不包含能源,如电池或发电机,那么就被称作无源网络。换句话说,如果存在一个或多个能源,那么组合的结果为有源网络。在研究电网络的特性时,我们感兴趣的是确定电路中的电压和电流。因为网络由无源电路元件组成,所以必须首先定义这些元件的电特性。就电阻来说,电压-电流的关系由欧姆定律给出,欧姆定律指出:电阻两端的电压等于电阻上流过的电流乘以电阻值。在数学上表达为: u=iR (1-1A-1)式中 u=电压,伏特;i =电流,安培;R =电阻,欧姆。纯电感电压由法拉第定律定义,法拉第定律指出:电感两端的电压正比于流过电感的电流随时间的变化率。因此可得到:U=Ldi/dt 式中 di/dt =电流变化率,安培/秒; L =感应系数,享利。电容两端建立的电压正比于电容两极板上积累的电荷 q 。因为电荷的积累可表示为电荷增量 dq 的和或积分,因此得到的等式为 u=,式中电容量 C 是与电压和电荷相关的比例常数。由定义可知,电流等于电荷随时间的变化率,可表示为 i = dq/dt。因此电荷增量 dq 等于电流乘以相应的时间增量,或 dq = i dt,那么等式(1-1A-3)可写为式中 C =电容量,法拉。

Some methods aiming at the two problems have been researched. First, the optimal number of ATE site can be calculated based on a cost model of DAT-ATE. Second, the problem of test schedule which is equitant with two-dimensional Bin-Packing problem is presented. Then a TCG denotation satisfied with T-admissible rule is more convenient for combinational optimization. With Simulated annealing algorithm, better test scheduling results can be achieved; but there is no great optimization space because the efficiency of scheduling is greater than 90%. Third, A novel test compression method——Multi-capture testing is proposed to compress the stimuli. And the ATPG results show that MC achieves high compression ratio which is greater than 90% in some large-scale circuits. MISR, widely used in LBIST, is employed to compress the responses. The aliasing analysis demonstrates that the fault coverage reduction is little due to the existence of aliasing. Fourth, an improved TIC (called S-TIC) aiming at structured test is proposed based on ARM's TIC. A MC scheduling algorithm is proposed to compute the SoC test time and combine MC vectors to SoC test vectors. The scheduling results shows that test time is greatly reduced when using the proper scheduling priority.
首先,给出了低成本ATE的成本模型,根据此模型得到最低测试成本时系统级测试调度的基本参数——测试Site数;其次,本文将DAT-Scan方式的SoC测试调度等价为两维BP问题,为有效地求解该问题,将该BP问题表示为TCG图并通过模拟退火算法解决其求解过于复杂的问题,调度的结果表明该方法在测试时间上有一定改善,并指出DAT-Scan测试调度效率已经大于90%,进一步优化的空间较小;第三,本文尝试通过测试压缩来解决激励所需的测试带宽,提出了Multi-capture结构并解决了MC测试过程中的&矢量&退化问题,MC测试的ATPG结果表明其测试压缩率很高(大电路接近90%);第四,在激励获得很高压缩比的情况下,测试响应也需压缩,本文采用LBIST中常用的MISR作为MC测试的响应压缩电路,理论分析和实验结果都证明了MC测试的别名对故障覆盖率影响较小(小于2%),并对两类别名的成因做了具体分析;第五,在MC测试及其响应压缩的基础上,本文改进了ARM公司的测试控制器TIC使之适合于MC测试,为了解决MC测试矢量合成问题,本文抽取了MC测试模型,通过固定优先级的MC测试调度模拟将MC矢量合成为ATE矢量,并模拟出了总的MC测试时间。

For Clark Haskins, MD, from New Mexico Oncology Hematology Consultants, Ltd, New Mexico Cancer Center, the data do not support the researchers' positive conclusions."The results were crummy," he told Medscape when asked what he thought of the strategy of using metronomic chemotherapy in advanced disease."The problem is that there are a lot of patients who don't want to take chemotherapy, so this strategy is trying to reach these patients," he said."Unfortunately, the data don't support that the strategy works."

The data from stress box indicate that the observed values usually are smaller than the theoretical ones, and the relationship between the vertical or lateral stress and the fill soil thickness can be described in a power function curve: a- a hb. The fact that the soil stress is bigger in the portion adjacent to the central part of gully and becomes smaller in the portion close to the side illustrates that the gully has an apparent unburdening effect. From the monitoring results of the settlement deformation during and after constructingperiod, the study conducts statistical system analysis and evaluation on the change of settlement with time.
