查询词典 U-bar

The mechanism is composed of two ball screws, U-type linear rails, linear bearings and flexible couplings. The permanent magnetic direct current motors are used as actuators. The rotary encoder is used to measure the angular position of the DC motor. The digital controller is implemented on the personal computer and a motion control card (EPCIO-6000). The objective of this thesis is to realize precise positioning control using a real-time motion control system on an X-Y table.

机械结构包括有滚珠导螺杆、U型线性滑轨组、线性轴承及可挠性连轴器等；致动器是采用永磁式直流马达(permanent magnetic direct current motor)；感测器是使用光学式旋转型编码器来量测马达旋转的角度；控制器则是以个人电脑为控制核心，搭配运动控制轴卡(EPCIO-6000)所组成。

By 1933 Zeiss had manufactured several proven refractors of the "E","A" and "AS" achromatic doublet designs, and apochromat triplets of the "U.V."

1933年，蔡司生产了"E"，"A"和"AS"等几款使用消色差镜头设计，并经过实际使用验证的折射望远镜，还有"U.V。"

And HP PLOT-U columns The inertness of the porous polymer allows the elution of a range of apolar and polar compounds, especially the most active and polar compounds such as H〓O, H〓S eluted symmetrically. It has been stabilized to withstand temperature of up to 300℃.

与一般的商品化PLOT-Q和PLOT-U型PLOT色谱柱相比，热稳定性和机械强度有明显的改善和提高，色谱柱最高使用温度分别提高了50℃和20℃（达到300℃和210℃）。

Schedule an appointment with an audiologist if your child has trouble learning letter sounds (particularly short vowels, such as "u" and "o"); confuses similar-sounding words (such as "on" and "in," or "to" and "through"); or asks questions that have already been answered.

如果你的孩子在学习字母发音上有困难，那么事先制定一个听力的计划。（特别是短元音，如" U "型和" O "）；混淆相似的词（如"上"和"中"或"去"和"通过"）或是问一些已经被回答过的问题。

By the single zircon U Pb dating method, the quartz syenite porphyny yielded an age of concordance (1 731±29)Ma, and the aegirine augite syenite and syenogebbro are dated upper cocordi...

应用单锆石U Pb法测定年龄，石英正长斑岩谐和年龄为( 1731± 2 9)Ma ，霓辉正长岩、正长辉长岩上交点年龄分别为( 1644± 14)Ma、( 1750± 65)Ma.1650～ 170 0Ma是碱性岩浆活动热构造事件的标志，石英正长斑岩被中元古代晚期的高山河组不整合覆盖，故以 1650～ 170 0Ma作为熊耳群的上限。1650～ 170 0Ma热构造事件是华北地块重大地质事件，有可能是进一步划分中元古代重要的年龄界限。

The split between the two groups can hardly be papered over.
