Methods Three experimental groups of ROS17/2.8 cells were cultured in rotating clinostat for 24 h, 48 h and 72 h respectively, 1 h before the end of culture, BMP-2 (500 ng/ml) was added into the medium, and the expression of total ERK1/2 and phosphated-ERK1/2 (p-ERK1/2) were detected by Western Blotting method at th...

方法在地面1G和回转器模拟失重条件下培养ROS17/2·8细胞，培养时间分别为24h、48h和72h。

When the rotor bearing journal of turbine-generator unit and the collector ring of generator are damaged, we can restore them on-line by TR series which are the systems that the rotor bearing journal of large-scale rotary machine is lathed subtly on-line and burnished.

汽轮发电机组的转子轴颈和发电机的集电环损伤可利用TR系列"大型回转机械转子轴颈在线精车与珩磨系统"进行在线修复，其精度可达到国际先进水平，在线修复可避免大范围拆装主设备，避免返厂加工的长途运输，可节省大量的检修时间，具有显著的经济效益。

It's a turn-around concept, where one side features a urinal and the other a sit-down commode.

这是一个回转的概念，其中一方具有小便池和其他静坐式马桶。

Based on this theory and method, this paper presents a new method and model for the SREM in-process measurement, which satisfies the need of real-time error compensation.

Before using a friction cone hoisting system, release the control lever of planetary mechanism, then operate the friction cone clutch's lever to engage the friction cone and the drum's cone surface, driving the drum to rotate and therefore start to hoist.

使用摩擦锥式提升系统时，将行星机构的操作手柄都松开，操纵摩擦锥离合器手柄，使摩擦推面与卷筒内锥面结合，从而带动卷筒回转，达到提升的目的。

The abstract lathe is in the machine manufacture uses a most widespread kind of engine bed, mainly uses in processing each kind of rotation surface (for example: In the outer annulus cylinder, the circular conical surface, the ring groove, the solid of revolution formation surface and so on) and the solid of revolution end surface, some lathes also can process the thread.

车床是机械制造中使用最广泛的一类机床，主要用于加工各种回转表面（如：内外圆柱面、圆锥面、环槽、回转体成型面等）和回转体的端面，有些车床还能加工螺纹。

The law of conservation of angular momentum may be demonstrated with a gyroscope.

角动量守恒定律，可以用回转器来演示。

For "T" type junctions, the copper can be given a turn around the constantan to keep it from melting back too rapidly from the arc area. Start with the constantan extended beyond the copper ring a short

对于"T"型热电偶的结球，铜能给康铜提供一个回转时间，防止它在电弧区域快速熔化，只要让康铜线比铜线长出一小段即可。

In order to meet the market requirement, the company has paid much more attention to technical innovation and investment in recent years, so that our products have developed from original eight types (0, 2, 3, 4, 6, 7, 8, 9) in early times when the company was established, into multiple series, nearly 100 types of structures and more than 2000 specifications with exterior dimension ranging from 100mm to 1800mm, as well as the self-lubricating joints, inch-size conus, slewing rings and split bearing, etc.
