小球

The location of the ball through the linear displacement sensor acquisition, controller position error calculated in accordance with the volume control to control the motor shaft angle, the angle of the control bar so that the stability ball to the target location.

小球的位置通过直线位移传感器采集，控制器根据位置误差计算控制量，控制电机轴的转角，从而控制横杆的角度，使小球稳定到目标位置。

Driver system for the stability of nonlinear and non-use of the theory of linear quadratic control law studies, select the ball location, speed and rod angle, angular velocity of the four variables as state variables, output variables for the ball position and bar angle, the establishment of linear state space equation and after the designs of clubs based on LQR control law, the design process simple and easy to realize the control law, simulation results show that the linear quadratic regulator robustness and stability.

球杆系统翻译，求高人针对球杆系统的非线性和不稳定性运用最优二次型理论进行控制律的研究，选取小球位置、速度和横杆角度、角速度四个变量为状态变量，输出变量为小球的位置和横杆的角度，建立状态空间方程并进行线性化后设计了基于LQR的球杆系统控制律，设计过程简单，控制律的实现容易，仿真结果表明了最优二次型调节器的鲁棒性和稳定性。

PTCA was performed for right coronary artery in two patients and for circumflex in one.

置入支架的指征：2例为夹层，1例为扩张结果不满意。2个支架脱落在右冠状动脉近段，1个支架脱落在左主干和回旋支之间。3例患者均使用相同的方法收取脱落支架，即用1.5 mm的小球囊穿过支架，加压至3～4个大气压，将脱落的支架和小球囊一起撤出，均告成功，且无并发症。

Embryo 7 weeks, Maxillary Tunisia Tunisia at the top connected to the formation of nasal and nasal Department, in the middle and small ball connected to the formation of Tunisia at the bottom of the nose and upper lip, two small balls connected to the formation of Tunisia in the midline nasal columella, lip people and ex-jaw.

胚胎第7周时，上颌突在上方与鼻侧突相连形成鼻侧部，在中线与小球突相连形成鼻孔底部和上唇，两个小球突在中线相连形成鼻小柱、唇人中和前颌。

A good drop shot is one in which the ball is on it ' s way down when it crosses the net.

一个好的小球应该是过网急坠的。4。一个好的小球应该是出乎你对手意料的。

If he has one weakness (that's a weakness relative to him, rather than anyone else) it's his drop shot, although when he has to he executes them better than any other player I can think of.

如果他有缺点的话，那就是他的小球，虽然当他必须要使用小球的时候他能打的比我能想到的任何人都好。

Based on the dynamics theory, calculate the motion equation of the ball on the plate.

最后根据动力学原理和小球在板上的受力及运动情况，解析出小球在板上的运动方程。

It is revealed that the maximum refractive index modulation coincides with the widest band gaps and the optimum volume fraction of the atoms is structure independent. The photonic bands of the face centered cubic ...

文中还计算了由各向异性介电小球构成的面心立方结构的光子能带并看到了禁带，这与各向同性介电小球构成的面心立方结构很不相同。

The slice ground stroke lends itself beautifully to the drop shot. There is almost no difference in the stroke until you hit the ball.

打切削球的准备动作更有助于击出完美的小球，因为在拍面接触球之前切削和放小球几乎没有区别。

The resul ts indicated:(1) When micrococcus existed,carbon steel corrosion was accelerated by a loose and heterogeneous biofilm formed on its surfaces;(2)Rpo an d Cc values were close after two days and four days immersion respectively in solutions with micrococcus,which indicated that the metabolization of bacteria became sta ble,and the biofilms under two conditions were tend to be ripe and accordant;(3) The equivalent circuits for situations without or with bacteria were proposed respectively,and the parameters in circuits were also calculated;and (4) Corrosi on reaction impedance with micrococcus showed dispersion effect.

结果表明：（1）小球菌存在时试样表面上所形成的疏松、不均匀的生物膜加速了碳钢的腐蚀过程；（2）有菌存在时暴露2 d、4 d的Rpo值和C c值较为接近，表明细菌的生长代谢过程渐趋于稳定，两种暴露条件下所形成的生物膜趋向于成熟一致；（3）分别提出了有菌和无菌条件下EIS的等效电路，并计算了相应的等效元件参数；（4）小球菌影响下腐蚀反应的阻抗行为存在弥散效应。

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。
