确切原因

R Yermack was not sure exactly why the executives were so implausibly lucky, but suspected that they had known their firm was about to announce good news, and were timing option grants to exploit this.

R YERMACK 不能确切肯定造成主管好运过人的原因，但怀疑主管知道公司将公布好消息，适时赠与股票期权以自肥。

So far it has been impossible to pinpoint a single cause for CCD, which strengthens the hypothesis that general environmental stress has weakened the immune system of A. mellifera .

迄今为止还不可能确切找出群体性瘫痪失调的单个原因，这增强了下面这个假设的可信性，即一般的环境方面的压力削弱了意大利蜜蜂的免疫系统。

The hematoma from cerebral amyloid angiopathy, sometimes multilobar, is always located in the brain cortices and the white matter beneath them. In the previous reports, the presence of cerebral amyloid angiopathy accounts for 5-10% of non-traumatic cerebral hemorrhage. However, it has been overlooked or misdiagnosed all the time because of the lack of tissue proof.

据文献记载约有5%至10%的非外伤性颅丙出止是因大脑类淀粉血管病变所引起，但由於其确切诊所须藉助於病理切片，所以易被忽略或被误诊为肿瘤出血等较罕见的原因。

"I don't know what the potential is," said Dr.

&我不知道确切的原因是什么！&

I don ' t know the exact reason why they embraced tightly.

我不知道确切的原因使他们紧紧拥抱。

No, that's precisely the reason I was shocked, because I had been going for 40 years or more with very considerable evidence that it was working exceptionally well.

不，确切地说，这是我为之震惊的原因，因为40年来或者更多，我一直都是这样走过来的，有相当多的证据表明：它正卓有成效地运转着。

We proposed that the non-adiabatic passage at zero-crossings of quadrupole splitting would not lead to the great loss of the spin locking signals, and the second-order quadrupolar interaction had significant effects on triple-quantum coherences, which was responsible for the fast decay of the signals; the both experiments and numerical simulations supported this point of view.

另外，在该谱仪上还进行了四极核钠-23的自旋锁定效率的研究；从含时Shr〓dinger方程出发，提出了一个更为确切的四极分裂过零处的绝热通过判据，并指出四极分裂过零处的非绝热通过不会导致锁定信号的快速消失，四极相互作用的二阶项对三量子相干的影响不能忽略，它是引起锁定信号快速消失的原因；实验和数字模拟的结果证实了这个理论。

Although its exact cause is unknown, birth control devices happen to be one of the culprits.

虽然其确切的原因是未知的，出生控制装置的出现将其中一名匪徒。

The reason for the inexact nature of this science is often attributed to the fact that people from around the world see planets differently form different latitudes, longitudes and time zones, hence such variations will always exist.

这些造成不确切的答案的原因，该是因为观察各个行星的发表论调者，通常是由分布在各地不同时区经纬度的人们所构筑，所以一些偏差是一直都会存在的。

It is difficult to determine the exact number of pawnshops in the U.S., because there are entities that resemble pawnshops in some respects that should not be considered as pawnshops.

很难确切计算出美国所有的当铺数量，原因是，有很多的商业实体是对传统意义上的当铺在某些方面进行了变革的结果，所以这样的实体可能不再是一般的当铺了。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
