不能确定的

In addition to determining that humans use chemosignals to attract one another, the findings could one day be used to create new therapies to correct hormone imbalances—most notably alternatives to cortisol replacement, which is used in treat maladies such as Addison's disease (in which the adrenal glands fail to pump out enough cortisol, causing muscle weakness, weight loss and low blood pressure).

除了确定人类确实可以用化学信号彼此吸引，这一发现还将有助于荷尔蒙失衡新疗法的开发——值得一提的是，这类新疗法可能取代皮质醇替代疗法来治疗阿狄森症（阿狄森症：肾上腺不能分泌足够的皮质醇，从而引发肌肉乏力，体重减轻和低血压等症状）。

To determine how extreme the distortion is, you can''t simply add up the values above and below the "ideal" plane and calculate the arithmetic mean.

要确定畸变的极端程度，您不能简单地把在"理想的"平面上下的值相加，并计算算术平均数。

By not controlling for the number of parents, sexual identity, marital status and biogenetic relationship to the children, the research often failed to isolate the real impact of gender on effective parenting, according to Biblarz and Stacey's study.

根据毕博拉兹和斯泰西的研究，由于不对父母的数量、性别认定、婚姻状况及生物起源关系加以控制，很多研究往往不能孤立确定性别对育儿的真正影响。

In addition, several Win32 based honeypots were deployed, but these were limited in number and could not be used to identify widespread trends.

此外还部署了一些基于 Win32 的蜜罐，但数量有限，因此不能用于确定普遍的趋势。

Can you explain to me how to use these idioms about which I ' m not sure ?

你能解释一下这些我不确定的短语的用法吗？

In recent years, many Virgos have watched their spouses suddenly begin to act like teenagers, or they want to "find themselves" and need to be alone while doing so, or they just get kind of kooky without being able to really define why.

近年来，许多比戈斯曾经看过他们的配偶突然开始像青少年，或者他们希望&发现自己&，需要独自在这样做，或者他们只是得到，而不能真正确定为什么样的怪人。

Prima facie is often confused with res ipsa loquitur ("the thing speaks for itself"), the common law legal doctrine which in its modern incarnation allows a tort plaintiff to reach the jury on the question of a defendant's negligence, despite the plaintiff's failure to produce any evidence explaining exactly how the defendant was negligent, by establishing circumstantial evidence from which unspecified negligence by the defendant can fairly be inferred.

Prima facie经常被与resIpsaloquitur这个法律术语相混淆。后者作为普通法中的一个法律原则，在现代的翻版就是允许一个侵权案件中的原告就被告的过失出现在陪审团的面前。尽管原告不能提供任何可以准确地说明被告人是怎样的过失的，但是通过建立起来的情境证据，被告不是很确定的过失就会被很好地推论出来了。

If it were even possible to lay things down exactly asthey stood, before the series of experimental politicks began, I am quite surethat they could not long continue in that situation.

如果真的就如他们树立东西那样推倒这些东西，那么，在这一系列的试验性的政治行为开始之前，我十分确定他们不能将那种情境持续多久。

ITD is adopted to get dynamic parameters of Bell Tower within traffic vibration amplitude for the first time,on this basis,the stiffness of mortise and tenon joint calculation model is derived through inversion,the questions of dynamic parameters unable to be identified with the traditional methods in environmental noise and the similar timber structure is unreasonably calculated due to tenon and mortise connection stiffness cannot be accurately determined are solved.

在此基础上，通过反演得到木结构榫卯连接计算模型的刚度，解决了噪声环境中无法按传统方法进行动力参数识别及类似木结构由于榫卯连接刚度不能准确确定而无法进行合理计算的问题。

Goals should be realistic and specific, but that doesn't mean they can't be flexible and are allowed for minor impediments.

我们的目标应该现实和确定，但这不是说他们不能有更多的灵活性，同时也允许有小小的缺憾。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。

The factory affiliated to the Group primarily manufactures multiple-purpose pincers, baking kits, knives, scissors, kitchenware, gardening tools and beauty care kits as well as other hardware tools, the annual production value of which reaches US$ 30 million dollars.
