地滑

I did not hire a coach when I first learned to ski, because it seemed so easy when looking at others do it - simply going down from top to the bottom of the hill!

在我开始学习滑冰时，并没有聘请教练，因为看着其他人滑起来是那么的容易－－轻而易举地就从山顶滑到了山底！

More general, spectrum shape was related with the shape of response function, dispersion angle affect the lowest spatial frequency, and color cycle number can modify the distribution of low and high spatial frequency to change the smoothing effect.

一般地，光谱形状控制空间响应函数形状，色散角决定所能匀滑的最低频率，色循环数可改变响应函数特点，调整对空间低频和高频的匀滑效果。

Schwing poppet valve hydraulic piston pump be used in many municipal and industrial projects world wide.Today,Schwing was recognized as technology leader of"Dewatered sludge Pumping System".Schwing pump can pumping the sludge even with 56%solid content,for other inorganic material even with 80%solid content.Schwing units have operated continuously for years with 99%availablity.For sludge storage,Available in circular or rectangular design,the sliding frame/push floor technologies provide low cost methods to store large volumes of material w你好le awaiting final disposal.Schwing sliding frame system in the bottom of the silo,disc harge the sludge with the screw into sludge truck or Schwing pump.The typical installation is silo with pump installed beside the dewatering mac你好ne.A Schwing silo can be integrated into the process stream to equalize surges in solids production and subsequently meter cake to final disposal.Large diameter storage silos are useful for truck loading,and finally,both sliding frame and push floor designs are effective as receiving stations used to accept sludge hauled in from other facilities.Ultimately,the storage volume of the silos and bunkers dictate the plant''s flexibility in disposing of the solids.

Limited slip differential is improved according to common differential. Not having the common differentials disadvantage of dividing the torque into two equal parts, limited slip differential can give most torque or even all torque to another driving wheel which is not revolving in order to make use of the friction of this driving wheel to produce enough traction. This will greatly increase the dynamical capability, the passing capability, the stability and the safety of automobiles on different friction roads. So limited slip differential is substitute for common differential.

防滑差速器是对普通差速器的革新与改进，它克服了普通差速器只能平均分配扭矩的缺点，可以使大部分甚至全部扭矩传给另外一个不滑转的驱动轮，以充分利用这一驱动轮的附着力而产生足够的牵引力，大大提高了汽车在双附着系数路面上的动力性和通过性，显著改善了汽车操纵稳定性，有效地提高了汽车行驶安全性，是普通差速器的理想替代产品。

Firstly, based on the sliding mode control and backstepping technique, a new attitude tracking controller is derived to control the attitude motion of spacecraft, the stability of the system is analyzed via Lyapunov method and the reaction wheel dynamics is also considered from the real applications point of view. The whole design process is divided into two steps: the first step is to use sliding control technique to design suppositional adaptive variable structure controller; and the second step is to design attitude tracking controller based on SMC and backstepping technique. Numerical simulations are performed to show that both tracking maneuver and vibration suppression can be accomplished effectively.
