For safety we should use dual valves to aid safe pressure reduction, and cap the sample outlets.

为了安全起见我们要在取样点设双阀以便于安全的压降，取样口还要加护罩。

Valves 28A and 28B in FIG. 1 have samples from various locations in the purification process connected to them and the sample location can be controlled with a computer.

图1中阀28A和28B具有在与它们相连的纯化过程中的不同位置得到的样品，可以用计算机控制样品位置。

The equipment used to test valve's lagging is designed, and piezo-pump with integral valves as sample is tested.

设计了阀振动滞后性测试装置，以整体开启阀压电泵为模型作了测试。

The sample and the particles then drift along the channels towards spin valves that have been prepared with different antibodies to the same target molecules.

Both the spin valves and the paraphernalia of channels needed to feed a sample to them are built onto silicon wafers using the same techniques employed to make microprocessors.
