查询词典 bit

The transmission ratio (cone/bit rotary speed ratio) of a mono-cone bit was tested on the bit test stand.

单牙轮钻头的牙轮转速与钻头转速之比是研究和设计钻头的重要参数。

By means of numerical solution method, drillstring's finite element models, and based on mechanical models of bit/rock interaction, the dynamic models for lateral vibration of a cone bit are established. The contact models of bit/wellbore interaction are created on the basis of the experimental data.

为探寻在实际钻井过程中钻头的运动轨迹和与井壁碰撞时撞击力的变化规律，利用有限元方法，建立钻柱横向振动的有限元动力学模型，并在考虑钻头-岩石互作用力学模型的基础上，建立了钻头横向振动动力学仿真模型，通过实验及相关数据得到预测钻头与井壁碰撞时撞击力大小的计算公式。

With the geometry model and kinematics model of roller cone rock bit, the interaction model of rock bit and rock is established which was based on the experiment of interaction between single tooth and rock. It is a good fundament for the computer simulation on working action of rock bit drilling.

在牙轮钻头几何学、运动学基础上，利用单齿压入与刮切岩石实验建立了钻头与岩石互作用力学模型，实现了对钻头在钻井过程中工作行为的仿真计算； 2。

In each selection period in which three scanning electrodes 312 are selected, a signal-electrode driving circuit 250 compares a bit string in accordance with the column elements corresponding to the selection of the scanning pattern with each of bit strings, which consists of a bit in each position of pieces of gray-scale data D for three pixels at the intersections of a signal electrode 212 and the three scanning electrodes 312, and conversion data Dt is generated in accordance with the comparison results.

信号电极驱动电路250在选择3条扫描电极312的各选择期间，将扫描图形之中与对应于该选择的列的要素相对应的位列，与将对应于信号电极212与该3条扫描电极312的交叉点的3个像素的灰度数据D中包含的由各位的位构成的位列进行比较，生成对应于该比较结果的变换数据Dt。

My top five works of art for Valentine's Day are a bit soft-centred, some might say, a bit corny and a bit cliched even - but that's Valentine's Day for you.

有人可能会说我的《四件情人节最不可错过的艺术作品》有点儿不够刺激，甚至有点儿陈腐，有点儿老一套，但这就是情人节。

For example, if a register isconnected to the data bus in an 8-bit machine. eachline of the bus connects to register.Because the databus will be an 8一bit bus, there are 8-bit Flip-flopsthat form the register, When there is information onthe data bus,and a particular register is selected toreceive data, all the Flip-flops will store data simultancously. This kind of register is refer is referred to as aparallel register.

例如，如果寄存器被联接到一台8位机的数据总线上，那么，该总线的每一条线均联接到寄存器上，因为数据总线是8位总线，所以有9个触发器来形成寄存器，当在数据总线上有信息，并且选择了一个特定的寄存器来接收数据时，那么所有的触发器将同时存储数据，这种形式的寄存器叫做&并行寄存器&。

For signed-bit values, if the number to be encoded is positive, an extra bit is necessary to preserve the leading 0; otherwise sign extension changes the bit value into a negative number.

对于带符号的位值，如果这个编码长度能够确定，一个扩展位必须保留第一位是0；否则，符号扩展将改变这个位值为负数。

Variable bit-rate allows a codec to change its bit-rate dynamically to adapt to the "difficulty" of the audio being encoded. In the example of Speex, sounds like vowels and high-energy transients require a higher bit-rate to achieve good quality, while fricatives e.g.

变比牲率允许编解码器动态调整比特率以适应的音频解码的&难度&，拿Speex来说，像元音和瞬间高音则需较高比特率来达到最佳效果，而摩擦音则用较少的比特即可完成编码。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
