Constant Angular Velocity mode and Constant Linear Velocity mode are integrated to build a single spindle motor control module to incorporate with long-seek servo. CAV mode and CLV mode are performed to show its feasibility. The experiment results showed that the pick-up-head can perform arbitrarily track-jump command, quite well.

研究重點(diǎn)主要集中在管內(nèi)流動(dòng)狀態(tài)特级婬片欧美国语高清视频一、濃度和速度分布免费A片一区二区三区视频、臨界流速及阻力損失計(jì)算四個(gè)方面。

The numerical results of stationary and transient Green'sfunction for high-velocity surface-head wave on some selected crystals are comparedThrough the above analyse,it is indicate that the first arrival wave mode is thelongitudinal-wave head-wave,and its propagate velocity is equal to the groupvelocity of the longitudinal bulk wave alone the surface.Furthermore,this modedoes not have the Δv/v effect,i.e.,its velocity is the same no matter the surface isfree or metalized.

通過對(duì)表面激發(fā)的瞬態(tài)和穩(wěn)態(tài)Green理論分析和數(shù)值計(jì)算五月婷婷久久久，表明在壓電晶體表面上實(shí)際上看到的最高速的最先到達(dá)的波動(dòng)模式是縱波頭波亚洲又黄的A片，它具有沿表面縱波的群速度又色又污视频网站，而且對(duì)壓電晶體，它不具有Δv/v效應(yīng)免费的黄黄网站，即在自由表面和金屬化表面其傳播速度是一樣的www.欧美视频，而壓電晶體表面波及偽表面波均存在Δv/v效應(yīng)。

Unfortunately,the trimexit velocity head alone is not agood predictor of such animportant phenomena.

可惜黄页网站网址在线观看，單靠閥門內(nèi)件節(jié)流出口速度頭并不能很好的預(yù)測這種現(xiàn)象另类日韩高清精品视频在线观看网站。

On the other hand,avalvetrim exit velocity head lower than 480 kPa will have a veryhighnoise level if the valve outlet mach number is notlow.

另一方面，當(dāng)閥門的閥門內(nèi)件節(jié)流出口速度頭低于480KPa時(shí)国产丝袜一级a片免费视频，如果閥門的出口馬赫數(shù)不處于較低的水平欧美黄片免费在线视频，閥門仍會(huì)有較高的聲壓級(jí)。

Also,this article willshow thathaving a trim exit velocity head lower than 480 kPa willstillgenerate a very high valve noise level if the valve outletMachnumber is high.

另外久久99国产综合精品第二页，這篇文章顯示在流體速度頭低于480KPa就要色色网，但閥門出口流體速度馬赫數(shù)較高的情況下仍會(huì)產(chǎn)生相當(dāng)高的聲壓級(jí)。

It can be seen from this article that the two methods have demonstrated the working capacity for calculation of frictional force and thermal load on surface of a hypersonic winged flight vehicle, which moves in dense atmospheric layers on a trajactory with stationary values of velocity head.

由文可見欧日XX片，對(duì)于在稠密大氣層內(nèi)九九精品视频在播放一，沿軌道運(yùn)行頭速度恒定的高超聲速有翼飛行器，能夠用本文所采用的兩種方法計(jì)算其表面摩阻和熱載荷久久av中文字幕免费在线观看。

After addition of surface active agent into sprinkling solution, for particle of 1 μm size, the filtration rate has increased from 40% to 70% approximately under the condition of head wind velocity of 1.5 m/s and spr4nkling density of 2.36 kg/(m^2s), and the filtration rate has increased from 30% to 60% approximately under the condition of head wind velocity of 2.8 m/s and sprinkling density of 2.36 kg/(m^2s).

在噴淋溶液中添加表面活性劑后黄色视频看黄色免费网，對(duì)于粒徑為1 μm的塵粒，在迎面風(fēng)速為1.5 m/s一级axi视频免费、淋水密度為2.36 kg/的條件下12345aa一级黄色网站，過濾效率由40%左右上升至70%左右。在迎面風(fēng)速為2.8 m/s欧美精品哟哟、淋水密度為2.36 kg/條件下巴西性XX在线观看，過濾效率由30%左右上升至60%左右。

Thus,theexample above demonstrates that a 4 valve with a singlestagedrilled hole cage can achieve a low noise level despite thefactthat the time exit velocity head is much great than the 480kPalimitations that some valve manufacturers advocate.

因此91网站最新网址，上例顯示了4的單級(jí)籠式套筒閥可以實(shí)現(xiàn)低噪音免费一片，盡管閥門內(nèi)件節(jié)流出口速度頭遠(yuǎn)超過480KPa。這就是一些廠家主張的這個(gè)方法的局限性在线免费观看日本y码视频网站。
