ac3

To quench 20 steel after different deformations above Ac3 temperature .

对20钢在Ac3温度以上采用不同程度的形变量进行高温形变后淬火。

In order to reduce the memory space of the system , AC3 program is optimized and hardware / software co-design method is used to optimize the memory space consumed in system level assemble level and hardware level .

为减少系统的存贮耗费，针对AC3程序进行了存贮优化，并提出了一种应用软硬件协同设计的方法，即从系统级、汇编级和硬件级进行存贮优化。

As the peak temperature of thermal simulation , which was higher than Ac3 , increased , the prior austenite grain size and the martensite lath size increased , and consequently the impact toughness depressed .

模拟热循环的峰温高于Ac3时，随着峰温的提高，奥氏体晶粒明显长大，马氏体板条尺寸也相应增大，因此冲击韧性相应下降。

With the build-in AC3 player , you can listen to the AC3 file , set the start time and the end time , split or cut any section of the AC3 file as needed .

随着建设中AC3播放器，您可以收听到AC3文件，设置开始时间和结束时间，分拆或削减AC3文件的任何部分根据需要。

When the steels thermal-simulated to the peak temperatures below Ac3 , the well-performed precipitation of carbides from the martensite matrix occured , which could soften the matrix and therefore increase the ductility .

模拟热循环的峰温低于Ac3时，高温下马氏体板条内的碳进一步析出，基体软化，塑性提高；

According to top-down design process of big hardware design project and extreme complexity of decoding process make it impractical to directly design DOLBY ACS decoding hardware , that is why I devoted myself to successfully designing DOLBY AC3 decoder in system level .

根据大型项目硬件设计TOP-DOWN的设计流程，考虑到DolbyAC3解码的高度复杂性，直接设计DolbyAC3硬件解码器比较困难。

Scatters diagrams and three statistical criteria ? mean squared error , mean squared relative error and score of fitness were used to evaluate the prediction performance . The three criteria of predicting Ac3 and Ac1 using neural network are 23.8 ℃, 14.6 ℃;

用散点图和均方误差、相对均方误差和拟台分值二个统汁学指标评价模型的预测性能人工神经网络预测Ac3和Ac1的三个统计学指标分别为23.8℃，14.6℃；

In this dissertation , some approaches are given to optimize the memory usage of SOC . Since the MPEG-2 decoding chip is a SOC , 32-bits embedded RISC CPU core is used to decode the AC3 and TS bit stream .

论文设计的MPEG-2系统集成解码芯片是一个SoC，该SoC采用32位嵌入式RISCCPU核Virgo进行音频AC3和TS流解码的计算任务，并承担SoC的管理；
