Amid the unknowns, the nearest thing to a certainty was that the war would end as messily as it began, with no clear win for either side.

在这些未知数中，最确定的一件事情就是同其开端一样，这场战争将结束于一团混乱之中，没有一方能明显获胜。

Although a few TK genes have been shown to be mutationally altered in specific human cancers (1), it is not known how many or how often members of the TK gene family are altered in any particular cancer type.

尽管有少数TK基因被报道在特定的人类肿瘤中有突变，但对整个TK基因家族中有多少个基因多少次在某一特定肿瘤类型中有突变，还是个未知数。

According to the number of unknown variables in ideal element fitting, variable substitution is adopted to convert the overdetermined nonlinear equations into overdetermined linear equations. Cumulative sum operator is used to solve the overdetermined linear equations.

根据理想要素拟合过程中待求未知量的个数，运用变量代换，将非线性超定方程组转化为线性超定方程组；对变换后的超定线性方程组施加累积算子，进行未知数求解；最后用仿真实例进行了分析，并与CIRP方法进行比较。

First, consolidation behaviors of phosphatic waste clay are simulated. Then, thaw consolidation of a frozen clay layer is discussed. Positions of each nodes, in addition to void ratio, are considered as unknowns; thus, geometry are continuously modified.

理论中所推导出的孔隙比的控制方程式将以一特别的移动式有限元素法加以求解，此种方法中与其他传统有限元素法的不同处在於除了孔隙比之外，各节点的位置亦考虑为未知数，因此问题的构形不断地被加以修正。

Suddenly, your whole life is disrupted and your future is, at best, uncertain.

突然之间，你的整个生活被打断了，而你的将来，在最好的情况下，也是个未知数。

I hope so, but everything hangs in the air at present.

我希望如此，不过现在一切都是未知数。

But since only registered Republicans were allowed to vote in Kentucky's closed primary, it is difficult to know how many other voters, even in Kentucky, will plump for a candidate who threatens to slash their entitlements and hankers after the gold standard.

但是在已经结束的肯州初选中只有已注册的共和党成员才有权投票，因此我们无从知道究竟会有多少选民会投票支持可能削弱他们的权利、竭力主张金本位的候选人，这在肯塔基州都是一个未知数。

The Summit is the beginning of ditching G-7. What to replace it hasn't jelled.

这场峰会是G7衰落的开始，但是，用什么取而代之，还是未知数。

I greet this sunrise with cries of joy as a prisoner who is reprieved from death.

明天是一个未知数，为什么要把今天的精力浪费在未知的事上？

Another important unknown is the extent to which globalisation unravels.

另一项重要的未知数，是全球化拆解的程度。

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。
