二进制数字

This is a convenient form in which to examine binary data because it collects 4 binary digits per hexadecimal digit.

这是一个方便的，表示二进制数据的形式因为每个十六进制数的数字由4 个二进制数集合而成。

In the binary system, the digit combination 10 has the value two, which is where the word binary comes from.

在二进制中，数字组合"10"的数值为二，"二进制"就是根据这个数值来命名的。

Because it is more superior than that of the binary scale FSK and OOK that the binary scale moves the looks key and accuses of the system in resisting noise performance and channel communication frequency band utilization ratio etc., widely used in digital communication.

二进制移相键控方式是受键控的载波相位按基带脉冲而改变的一种数字调制方式。由于二进制移相键控系统在抗噪声性能及信道通信频带利用率等方面比二进制FSK及OOK的优越，因而被广泛应用于数字通信中。

In this coding scheme, each of the digits(0-9)in the decimal system is coded as a four-digit binary number, and these binary number are added in sequence as in the decimal number system.

在这个编码方案，每一项数字（ 0-9 ）在小数制编码为4位数二进制数，而这些二进制数已加入顺序，在十进制数系统。

In a typical implementation, the range is determined by the number of bits used in the exponent, and the precision by the number of bits used in the mantissa (giving the maximum number of significant digits that can be exactly represented).

在一个典型的实现中，范围是由用于表示指数的二进制位数量所决定，而精度是由用于表示尾数(给出了可以精确表示的有效数字的最大位数)的二进制位数量所决定。

For example, say you have the number "9", which is "1001" in binary. If you want to know if that sequence contains the number "8"(1000), you can do

如果你用一个数字9，它的二进制代码是1001，如果你想知道这个二进制序列中进否包含8（1000），那么你可以这样做

An octal number system .

有时应用在二进制记数系统中表示数字的一种术语（对比二进制编码的十进制表示或其它用"0"和"1"的表示）。

In computing , most significant bit is the bit position in a binary number having the greatest value. The msb is sometimes referred to as the left-most bit , due to the convention in positional notation of writing more significant digits further to the left.

在计算机运算中，最高有效位，是指在一个二进制数中具有最大值的那一个二进制位。msb有时也被称为"最左边的位"，这是因为在权位记数法中习惯上将较大的有效数字顺序的写在左边。

Thirdly, in order to manage these data better, the paper advances the organization methods of data of commixed Database of Geo-spatial Framework model by integrating some advanced database technologies such as RDBMS and the Spatial Database Engine, namely on the basis of database and the data of Geo-spatial Framework divided in a preceding part of this paper, it describes layer-delaminating, block-dividing, slice-connecting, map-dividing and BLOB etc. to organize spatial data, including DLG, DOM, DEM, and thematic data, taking example for the data of urban planning. At the same time it also realizes integrated management of these data.

然后，本文以管理这些地理空间框架数据为主要目标，集成关系数据库管理系统以及空间数据引擎等相关技术，提出了地理空间框架混合数据库数据组织方法，即以地理空间框架数据库为基础，以分类后的地理空间框架数据为对象，通过采用分层、分块、连片、分幅以及大二进制对象等方法对基础空间数据(包括数字线划数据、数字正射影像数据、数字高程模型数据)和专题数据进行统一组织，并实现了这些数据的关联一体化管理。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
