Until now, controlling the conduction of heat through solid objects has been a tricky engineering challenge.

时，控制热量通过固体传导对工程界还是一个棘手挑战。

So, the inside is heated because of conduction.

所以，内部也因为传导得到加热。

The fact that this conduction only works in one direction is extremely useful!

二极管只能单向导电特性对我们非有用！

Conduction, however, is most similar to the transmission of sound.

然而传导很像声音传播。

This trading of heat can happen three different ways: by convection, conduction, and radiation.

对流、传导和辐射。

Your body creates its own warm bubble of air just above the skin thanks to conduction.

由于传导，你身体会在皮肤上方产生热气绝缘体。

Less commonly, the signal can move in the opposite direction, called AVRT with antidromic conduction.

不太见是，冲动可以反向传导，称逆向传导房室折返性心动过速。

Well, if we run the xenon stream through the cryocooler, it'll be cooled immediately before it reacts with the conduction.

好吧，那如果我们让疝气流通过制冷机那它就会在与传导物发生反应前就立即冷却。

Then they did a " bone conduction" hearing test, where vibrations are transmitted directly onto the skull, from behind the ear.

然后，他们做了一个“骨传导”听力测试，振动直接从耳朵后面传到头骨上。

Conduction is the transfer of heat between solid objects, convection uses the movement of fluids, while radiation relies on electromagnetic waves.

传导指是两个固体之间热量，对流运用流体运动，辐射利用电磁波。

They are a continuation of the conduction fibers that transmit the electrical impulse down the ventricles.

它们是传导纤维延续，这些传导纤维将电脉冲向下传递到心室。

Now this can be a cell that’s part of the conduction system or it can just be another cardiac muscle cell.

这个细胞可能属于传导系统一部分，或只是一个心肌细胞。

The starting point of the intrinsic conduction system is the sinoatrial node, or SA node.

内在传导系统起点是窦房结。

A person inside will radiate body heat, which moves around the igloo by convection, and is lost through the walls by conduction.

冰屋里面人会辐射热量，通过对流作用，热量不断地在屋内流动，但这些热量，由于传导作用，会散发出去。

Advanced diagnostic techniques like electromyogram and nerve conduction studies may be used to further investigate if the motor symptoms are due to damaged nerves.

肌电图、神经传导研究等先进诊断技术可用于进一步探究运动系统症状是否由神经受损引起。

This ability is thanks to the intrinsic conduction system, which is the internal regulating system that causes the heart to contract rhythmically.

这种能力是由于内在传导系统，这是导致心脏有节奏收缩内部调节系统。

These blocks or delays usually happen because of some sort of damage or fibrosis to the electrical conduction system, the pathways that conduct the electrical signal.

心律失一般由心脏传导系统（即电信号传导通路）受损或纤维化导致。

The impulse is now passed from the bundle branches to the terminal branches of the intrinsic conduction system known as the Purkinje fibers.

脉冲现在从束支传递到被称为浦肯野纤维内在传导系统末端分支。

This ability is thanks to the intrinsic conduction system, which is defined as the internal regulating system that causes the heart to contract rhythmically.

这种能力归功于内在传导系统，内在传导系统被定义为使心脏有节奏地收缩内部调节系统。

Last year, about 1.5 million Brazilians lost their jobs because they're not willing to invest in Brazil because of the conduction of the president over the government.

去年因罗塞夫执政失职，巴西投资市场惨淡，约1500万人失业。
