查询词典 valid bit

In this paper, based on MPEG 2 Test Model 5 (TM5) bit rate control algorithm, there are some improvements proposed:① an intelligent integral action is proposed for improving the control precision of bit rate;② after using DCT AC coefficients to define the measure of macroblock and picture coding difficulty, an improvement on target bits allocation is proposed for the decoded picture quality and conformance including scene change, which can adjust the target bits allocation adaptively by their measure.

针对MPEG－2测试模型5（TM5）比特速率控制算法进行了以下改进：①引入一种智能积分作用，有利于提高比特速率的控制精度；②采用DCT交流系数定义宏块和图象的编码难度测度，然后提出了改进的目标编码量分配策略，即根据编码难度测度自适应调整图象和宏块的目标编码量，有利于提高包括场景变化在内的图象解码质量及其一致性。

After a brief review about the problems of bit rate control for MPEG video coding, two optimizations are proposed based on MPEG-2 Test Model 5 (TM5) algorithm:①An intelligent integral action is introduced for improving the control precision of bit rate;②After using DCT AC coefficients to define the measure of macroblock and picture coding difficulty, an improvement on target bits allocation is proposed for the decoded picture quality and conformance including scene change, which can ajust the target bits allocation adaptively by their measure.

文中首先对MPEG视频编码比特速率的控制问题作了简要回顾，然后针对MPEG-2测试模型5(TM5)算法进行了以下优化：①引入一种智能积分作用，有利于提高比特速率的控制精度；②采用DCT交流系数定义宏块和图象的编码难度测度，然后提出了优化的目标编码量分配策略，即根据编码难度测度自适应调整图象和宏块的目标编码量，这样有利于提高包括场景变化在内的图象解码质量及其一致性。

The easiest way to do this is to make sure you use a register for the address, since any effective address containing a 32-bit register is forced to be a 32-bit address. So you can do

最早的解决方案保证你使用了一个寄存器用于保存地址，因为任何在32位寄存器中的有效地址都被强制作为一个32位的地址，所以，你可以

Aforetime these were 8-bit microcontrollers such as 8051, and now these are 16-and 32-bit microcontrollers.

从前，它是8位的控制器，例如8051，现在它们是16位或者32位微控制器。

Bit by bit, just because you have ZhangHan, live in my heart, every minute, lingering aftertaste.

一点一滴，只是因为你ZhangHan，住在我的心中，每一分钟，挥之不去的回味。

The almirah that says a woman forever not quite big, it is actually in network game world, you also hope your blanket roll can be a bit older for certain, again a bit bigger.

都说女人的衣橱永远不够大，其实在网络游戏世界中，您肯定也希望自己的背包能大一点，再大一点。

Their amassment are running out bit by bit.

他们的积蓄一点点地消耗殆尽了。

Based on Rice fading channel, and taking the effect of bit error rate of the angle of elevation of satellite coverage into account, A bit error rate formula and computer simulation figures are given.

以莱斯衰落信道为基础，考虑卫星覆盖仰角对误码率的影响，推导了误码率的解析表达式。

This is due to the fact that everything is converted to 32-bit or 64-bit before doing the actual arithmetic operation.

这是由于事实：每件事物被转换到 32个位元或者 64-在做真实的算术运算之前咬了。

One should also remember the higher productivity of 64-bit versions of programs which is caused by a greater number of registers, extended abilities of floating point arithmetic and the possibility of working with 64-bit numbers.

人们应该还记得64更高的生产率，这些是由更多的寄存器位版本的程序造成的，扩大了浮点运算能力，与64位数字的工作的可能性。

For the head-teacher of the class said that I had seriously broken the school rules,which led me to a three-day suspend class.

为什么呢？因为我的班主任说我严重的违反了校规，于是让我停课三天。

Many of them believe that the conversion of thousands of working-class folk in England spared that nation from the mass carnage and the tyranny that came with the revolution in France.

他们之中有许多人相信，在英国数以千计的劳工阶级之悔改信主使英国免於遭受如法国大革命所造成的大屠杀和专制暴政。
