It's a chimney that allows air to move freely without mechanical systems.

这种烟囱可以让空气自由流动，完全不需要机械系统的助力。

Mechanical systems, Lawson says, " double if not triple" the cost depending on the number of zones inside.

劳森说，机械系统的成本“翻番甚长两倍”，这取决于温室内部区域的数。

The researchers even created a simple mechanical system, where adding a bit of energy made one ring revolve around the other.

研究人员甚创造出种简易的机器系统，在此系统中只要上点能，就可以使环带动另环转动。

Bobrick, of Hartley Botanic, says that while the price can be lower, mechanical systems can add 50% to 100% to the total.

哈特利植物公司的鲍勃里克说，虽然价格可以降低，但机械系统的价格却会使总成本50％100％。

These features reduce the need for mechanical  systems to provide services as the building does it automatically.

这些功能减少了对机械系统提供服务的需求，因为建筑物会自动提供服务。

In a larger greenhouse, there are partitions and mechanical systems (automated shades and vents, fans, heaters, water pumps) that break the structure into zones.

规模更大的温室里，安装有隔板和机械系统（自动遮阳和通风口、风扇、热器、水泵），它们将温室分成若干区域。

They use Schrodinger's equation to calculate different waves that describe a quantum mechanical system, like that electron you've been trying to measure.

他们使用薛定谔方程来计算描述子力学系统的不同波，就像你可能试图测的电子样。

If Freddy was just a normal animatronic he would work with a set of mechanical systems inside his body that make him move.

如果 Freddy 只是个普通的电子动物，他会使用他体内的组机械系统来移动。

That probability is predicted by the wavefunction, an equation that relates some of the properties of a quantum mechanical system, like an electron or atom.

概率由波函数预测， 与某些属性有关的方程 子力学系统，例如电子或原子。

The continuous nature of tape made it easy to handle mechanically, and the holes could be reliably detected with a mechanical or optical system, which encoded instructions and data.

胶带的连续性使其易于机械处理，并且可以使用编码指令和数据的机械或光学系统可靠地检测到孔。
