The effect of small amount of cobalt on structures and propertiesof invar steel has been investigated.

Who but a cockeyed optimist could possibly imagine that relationships between the currencies of widely diverse national economies could remain rigidly fixed over prolonged periods, if not indefinitely?

除了昏头昏脑的乐观主义者，还有谁能想象，差别很大的不同国家经济体，它们的货币之间的关系能够长期固定不变呢？

In the first part, for competitive discrete-time dynamical systems on a strongly ordered topological vector space, we prove that any α-or ω-limit set is unordered and lies on some invariant hypersurface with codimension one, which generalizes M.

在第一部分中，对于强序拓扑向量空间上的竞争离散动力系统，我们研究了极限集的序结构和极限集的几何位置，证明了任何α-或ω-极限集是无序的且位于一个完全无序的，余维为1的不变Lipschitz流形上。

In Chapters 3 and 4, we study Dirac cohomology of unitary representations with a regular lambda-lowest K-typeμusingθ-stable data.

在第三和第四章，我们利用θ不变参数研究了最小K-型正则的酉表示的Dirac上同调。

When inlet relative humidity increases, the Colburn factor increases and the friction factor almost remains unchanged.

当入口相对湿度增大时，换热因子增大，而摩擦因子则几乎不变。

When inlet relative humidity increasesthe Colburn factor increases and the friction factor almost remains unchanged.

当入口相对湿度增大时，换热因子增大，而摩擦因子则几乎不变。

Our domestic products remain the same, however, for export we have to produce more cold break and pack in different containers than we are used to, and significantly more in drums.

国内产品的数量保持不变。但对于出口，我们必须生产更多冷破产品、使用不同包装，特别是桶装。

I think it is commendable that he has never changed his spiritual pursuit in for a dozen years.

我觉得难得可贵的是他十多年来不变的精神追求。

All other thing being equal, so the argument went, a subsequent fall in the dollar might be expected to give a compensating boost to dollar commodity prices.

人们还认为，在其他条件不变的情况下，美元贬值也许有望补偿性促使以美元标价的初级产品价格提高

Common salt, although dissolved in water, does not change its chemical properties.

尽管食盐溶于水，但其化学性质不变。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
