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

这种烟囱让空气自由流动，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“翻增长两倍”，这取决于温室内部区域的数量。

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

研究人员创造出种简易的机器系统，在此系统中只要加上点能量，就使环带动另环转动。

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。

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，虽然价格低，但机械系统的价格却会使总成本增加50％100％。

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、加热器、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量子力学系统的不同波，就像你能试图测量的电子样。

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 量子力学系统，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，并且使用编码指令和数据的机械或光学系统靠地检测到孔。
