不能交换

"I am sick of this useless butchery of young Americans, and in exchange of these four days of weather favorable to combat, I will provide you enough Boches to keep your accountants occupied with months of work."

我再也不能忍受这些美国年轻人遭受无意义的屠杀，我会送给你足够的德国鬼子保证让你在天国的会计师们忙上整个月来交换这4天适合作战的好天气的。

In noncommutative scalar field theories, the appearing of nonplanar diagrams is related to permutation symmetry of field functions in the interaction Lagrangian, while in NCQED we can not arbitrarily change the positions of field functions in the interaction Lagrangian because different positions of the field functions correspond to different representations of the gauge group.

这里需要特别指出的是NCQED的非平面图产生的原因与非对易标量场根本不同，非对易标量场非平面图的产生是和相互作用拉氏量密度中场函数间位置的置换对称性有关，而在NCQED中我们不能随便交换相互作用拉氏量密度中场函数的位置，因为场函数的不同位置对应着规范群的不同表示。

I have never understood why anyone would want to swap a delicious pat of butter churned from milk for a manufactured hotchpotch of oils, artificially hardened to create margarine.

黄油 我从来都不能理解为什么有些人会想要把一块美味的搅拌好的黄油交换成一份杂烩的强化的人造黄油。

In order to avoid the inconveniency of such situations, every prudent man in every period of society, after the first establishment of the division of labour, must naturally have endeavoured to manage his affairs in such a manner, as to have at all times by him, besides the peculiar produce of his own industry, a certain quantity of some one commodity or other, such as he imagined few people would be likely to refuse in exchange for the produce of their industry.

因此，他们就不能互相提供服务。为了避免此类情况所带来的不便，分工被采用后各时代中的每个谨慎的人都会尽力以如下方式管理自己的事物：除自己行业的特殊产品之外，总是持有一定数量的某种物品，在他看来，用这种物品和任何人交换都不大可能遭到拒绝。

For most of the instructional theorist, LOM is not sufficient to make learning object support learning.

教学设计理论界认为，仅仅能够进行信息交换的学习对象在很大程度上还"不能用于学习"。

Security guards have been placed on landfill sites in Tel Aviv to keep treasure hunters away, as word spread in Israel of what must be the worst exchange since Aladdin's battered old magic lantern was swapped for a shiny new one.

安保人员被派到了这些垃圾填埋场的周围，这样可以使特拉维夫的寻宝者不能随意接近这里。自从用一个崭新的油灯换掉了阿拉丁那显得破烂不堪的神灯以后，以色列流传的最糟糕的词就是--交换。

If power cannot be "exchanged" in accord with this minor cycle of seduction, challenge and ruse, then it quite simply disappears.

如果力量在这个诱惑的小循环内不能被交换，挑战与诡计那时将会非常简单的消失掉。

It allows populations that are indistinguishable morphologically to be classified as separate, sibling species because they do not interchange genes.

该概念将没有明显形态学差别的种群分成分离的姊妹种，因为它们不能彼此交换基因。

Now, I agree that you have to — yeah, there are certain concessions and, you know, if you use a slide projector, you're not able to have the bad type swing in from the back or the side, or up or down, but maybe that's an OK trade-off, to trade that off for a focus.

我现在同意你需要有某种程度的让步，你亦知道如果你使用投映机你将会不能使用那些不好的模式从后边，或从旁边，或从上或下转出来。这或许是一个不错的交换。

The somatic hybrids usually showed specific bands and combined all the bands of both parents. In combinations, some new bands were detected, and occasionally specific bands of parents were lost, which indicated that chromosome recombination and exchange happened after fusion. Additionally, in some combinations, specific bands from leaf parent were detected, which revealed the plants were of putative hybrid origin, because leaf protoplast cannot redifferentiate by both single culture and co-culture.

体细胞杂种一般表现为具有双亲的特征带，且综合双亲的所有带，但在部分杂种中检测到了双亲都没有的新带，也发现有丢失亲本的特征带或共有带的现象，说明融合后染色体发生了重组和交换；有的引物只检测到叶肉亲本的特征带，根据柑橘叶肉细胞无论单独培养还是共培养均不能再生的事实，可推测其为体细胞杂种或二倍体叶肉亲本型胞质杂种。

Do you know, i need you to come back
