数字

Numbers are written using positional notation, in which the digits are arranged in succession, the position of each digit has a place value, and the number is equal to the sum of the products of each digit by its place value.

数字被使用在位置记法，这些位置被安排连续的数字，每一个位置都有自己的位值且位值等於每个数字按照本身位值的和。

CI is 101; IC is not even a valid Roman numeral (because you can't subtract 1 directly from 100; you would need to write it as XCIX,"10 less than 100, then 1 less than 10").

CI 表示 101；而IC 甚至不是一个合法的罗马字母（因为你不能直接从数字100减去1；比需要写成XCIX，意思是比100 小10，然后加上数字9，也就是比 10小1的数字。

It mainly enlarges the digital to tallies chip through Amplifier. It holds the sampling digitalpass to convenience transforming for the chip through sample and hold Circuit, thus it can complete the measurment of current digital y.

主要是通过放大电路将采样到的模拟量放大到和芯片相吻合的数字量，通过采样保持电路将采样的数字量保持住以便后面的芯片进行转换，从而完成电流数字量的测量。

With rapid advancements of digital video, however, there is lots of digital video systems having different spatio-temporal sampling ratio, having different standards and different formats, having different display equipment, in order to carry out different formats conversion.

随着数字视频技术迅速发展，产生了各种数字视频系统，具有不同的时空分辨率要求，导致了不同的格式的存贮，传输和显示数字视频的标准出现。

The system controls a tunable fiber Fabry-Perot filter with sawtooth wave voltage and synchronous signal of its digital phase to interrogate FBG sensors in a single fiber. Meantime, a reference FBG and a digital thermometer provide an accurate reference wavelength, which is used to calibrate the wavelength readout of the TFFP in real-time by a digital signal processor.

解调系统利用锯齿波电压信号和数字相位同步信号控制可调谐光纤法布里珀罗滤波器，对光纤光栅传感器阵列进行扫描式寻址，同时采用非测量环境中的参考光栅和数字温度计提供精确的参考波长，并由高速数字信号处理器实时校准滤波器的波长读取值，很好地消除了滤波器调谐的温度漂移、非线性和蠕动性引起的测量误差。

The ultrasound diagnostic equipment using the technologies of digital scan conversion and digital beam forming is defined as the digital ultrasound diagnostic equipment.

采用数字扫描变换技术和数字声束形成技术的超声诊断设备被称为全数字超声诊断设备。

The hardware circuitry of the whole digital scan conversion system is realized through the complex programmable logic devices so as to improve stability, flexibility and real-time of the digital hardware circuitry. A high-performance digital scan conversion system is researched and developed.

整个数字扫描变换系统的硬件电路都使用复杂可编程逻辑器件实现，增加了数字电路系统的实时性、稳定性和灵活性，设计和实现了一种高性能的数字扫描变换系统。

Based on the summarization of the present research, the future system frame of the blind digital image forensics is proposed. According to the natural characteristics of digital image, the principles of constructing the standard testing database of sample images are also put forward. Moreover, the extensible topology structure is set up and the size of the database needed theoretically is calculated statistically.

在总结前人工作的基础上，提出了数字图像盲取证的系统框架；利用数字图像自然属性特征，根据数字图像取证的测试需求，提出了取证测试专用的标准图像样本数据库建库准则，建立了可拓展的图像库拓扑结构，并利用统计学方法计算了所需的建库规模。

The importance of setting up correct concept of significant digit in analytical chemistry was also emphasesed.

介绍了有效数字与相对误差的关系，有效数字的记录、修约、计算等，强调了在分析化学中树立正确的有效数字概念的重要性。

Note: the first two digits are significant;third digit denotesnumber of zeros; R=decimal point.

0R51R0224 注：头两位数字为有效数字，第三位数字为0的个数；R为小数点。

I will endeavour to find you some assistance.

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
