零位置

It's only about 25 miles from Kniss's office to her home, but driving to her little bit of heaven in the evenings is a grueling 75 minutes, meaning that, on average, her speedometer is hovering just above zero.

也就是说平均算下来车速器(speedometer 是汽车仪表盘上显示速度的车速表)基本一直停留在刚刚过零的位置而已。

At this time, the amplifier output current is zero, the servo valve closed, hydraulic cylinder driving the valve plate parked in the corresponding position of qT.

这时，放大器的输出电流亦为零，伺服阀关闭，液压缸带动的阀板停在相应的qT位置。

The results indicated that the axial velocity distribution of the mixture was a parabola-like curve along the radius and the change of the velocity was larger in the region within 0%～25% of the pipe width (about 15 mm) from the pipe walls, but smaller in other positions. The vortex changed greatly in the region within 0%～16.7% of the pipe width (about 10 mm) from the pipe walls and then decreased gradually to zero at the pipe center.

结果表明，混合颗粒的轴向速度呈类似抛物线状分布，在靠近管壁约0%～25%管宽范围内，即在试验装置距管壁约15 mm范围内，轴向速度变化较大，其他位置处变化较小；涡量在靠近管壁约0%～16.7%管宽范围内，即在试验装置距管壁约10 mm范围之内变化明显，从距离管壁10 mm到竖直管中心涡量逐渐减小到接近为零。

The definition of generator angle is proposed in this paper. A new method to deduce generator angle by using rotor rotation signal is illustrated, which compares the phase difference between GPS timing pulse and RRS. Using only mechanical signal, the technique unfreezes limitation of zero-cross of generator terminal voltage during transient process. Automatic correction of initial generator angle is also proposed .

本文介绍了同步发电机绝对转子角的定义，提出了一种测量绝对转子角，进而获得高精度的相对转子角的方法；此方法不使用机端电压过零整形脉冲，而是将机组键相脉冲与GPS 定时脉冲比相，并能够自动整定初始位置角，因此，测量结果不受发电机运行状态的影响，能够在各种运行方式和扰动情况下获取高精度的绝对转子角。

By simplifying the mechanical model,constitutive relation defined in principal direction based on elasticity theory with different moduli was rebuilt in common ordinates,and tension-compression area was divided.

通过合理简化模型，将不同模量弹性理论中定义在主坐标系下的本构关系重新建立在普通坐标系下，进行拉压分区，从而推导了考虑自重且顶部有水平推力的不同模量弯压柱近似弹性力学解答，并由横截面上正应力为零判定了中性层的形状和位置。

The hotel's unrivaled location enables all the guests to have direct access to the marina as well as the International Yacht Club.

由于得天独厚的地理位置，使得所有入住酒店的宾客都有机会与青岛海港及游艇俱乐部零距离接触。

Located in the junction point of the axle wire of Shenzhen and Shennan Road, Crystal Island is the junction of living axle and transportation axle, Crystal Island is on the zero kilometer-position of Shenzhen.

水晶岛位于深圳市中轴线与深南路的交汇点，是生活轴与交通轴的交汇，并且是深圳零公里标识所在的位置

The influences of gyro constant drift and accelerometer bias on alignment precision are eliminated by the two-position alignment method.

双位置对准方案，消除了陀螺常值漂移和加速度计零偏对对准精度的影响。

In order to solve the problem, in this dissertation, a new IA technology based on wavelet-filtering and two-position alignment is proposed. The useful signals of sensors are gained by wavelet filtering; the error angles, constant drifts of FOGs and biases of accelerometers are computed through signals at two positions.

对此，本文提出了一种基于小波滤波方法和二位置对准方法相结合的初始对准技术，采用小波滤波方法提取传感器的有用信号，利用两次转位的信号解算初始对准的误差角、陀螺的常值漂移和加速度计的零偏。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
