也就是说

The food is the same as in other prisons,--that is, very bad; the lodging is very unhealthful, but, on the whole, passable for a dungeon; but it is not that which I wish to speak of, but a secret I have to reveal of the greatest importance.

吃的东西和其他监狱一样，也就是说，坏极了，住的地方非常不卫生，但既然是地牢，也总算还过得去。这都没什么关系。我要讲的是一个秘密，我所要揭露的秘密可是极其重要的。

Yeast is a unicellular micro organism, that is to say, it is a living organism whose individual units are visible only under the microscope.

酵母是一种单细胞的微生物，这也就是说，它是一种个体只能通过显微镜才能观察出来的活的生物。

That is to say, people's human rights are attached to the society, once the society becomes unintegrated, results of infringing, damaging and discriminating human rights will be inevitable.

也就是说，人类的人权寄存于社会上，只要社会出现不融合，都会出现侵犯、损害、歧视人权的现象。

That is to say, we would have nothing more meaningful than an uninterpreted formal language, formal rules of inference, and a subset of the set of well-formed formulas as axioms.

也就是说，我们持有的有意义语言甚至超不过一个尚未解释的形式语言、形式推理规则和作为公理的合式公式子集。

But in 2007, scientists made a revolutionary breakthrough. Three different groups simultaneously announced that they had converted unipotent, mature skin cells back into an undifferentiated state. In other words, they had created cells that behaved like embryonic stem cells without using any embryo derived materials. These new cells, dubbed "induced pluripotent stem cells" or IPS's could then be converted into a variety of different cell types, such as pancreas, muscle or brain cells. The IPS's were created by inserting certain genes into the DNA of the adult cells.

不过，在2007年，科学家已经取得了重大突破，三个不同组织同时发表声明称：已经能将成熟皮细胞转化回心肌细胞，也就是说不通过胚胎组织就能让细胞具有胚胎干细胞的属性，能够让多种不同类型的细胞细胞如胰腺细胞，肌肉细胞或脑细胞重新转化为人造胚胎干细胞，将某种组织注入成体细胞DNA中便能产生IPS'S。

It belongs to the mollusk class gastropoda.It is also a univalve,which means that the shell consists of a single valve or piece.

它属于软体动物类中的腹足动物纲，属于单壳软体动物，也就是说，这个贝壳只有一个单壳或单片。

It is axiomatic in communication studies that shaping anyone's expression of anything - observation and concern or anything else - is an often unrecognized "specific universe of discourse", that is, what one will or will not talk about and how.

传播学的研究表明，塑造某人对任何事物--包括观察、关注或其他--的表达，通常都不被认为是"特定领域研讨"的内容，也就是说，这个人可能说什么，不说什么，怎样说。

Each emotion can be pure or impure; that is, mixed or unmixed.

也就是说蚂蚁知道不动的蚂蚁也能是活着的。

In other words, unregistered sites will become unavailable to users in China.

也就是说，未登记的网站，将会无法被中国网民访问。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
