能交换的

The results showed that all of them could detect the presence of ZFY DNA sequences except a 46 XX"male"and a 46 XX hermaphrodite, our findings confirmed that Ferguson-Smith〔1966〕 forwarded the hypothesis that the X-Y intercharge model for XX maleness can be regarded as an abnormal exchange initaited in a region proximal to TDF and extending to the telomere,and,also strongly suggested that ZFY gene palyed an important role in sex determining of human.

结果除一例46XX两性畸形，一例46XX&男性&外，余均能检测到ZFY DNA序列(ZFY DNA序列存在于46XX真两性畸形和45XO Turner's综合症，在国内外尚未见报道)。证实了1966年，Ferguson-Smith提出的理论：在父源减数分裂期间，X-Y发生不等交换，导致Y染色体DNA插入性易位。XX男性是由于Y染色体上的TDF基因转移至X染色体上所致。

The transesterification reaction among poly,poly(ethylene 2,6- naphthalate),and PET／PEN copolymer were studied with1H-NMR.

通过用1H-NMR对聚对苯二甲酸乙二酯与聚2，6-萘甲酸乙二酯、PET/PEN共聚物的共混物酯交换反应的研究，测得了反应速率常数、反应活化能和诱导期。

In this dissertation, In this dissertation, the magnetism property on the exchange bias of NiFe/PtMn films with the insertion Cr were systematically investigated.

本文中插入层Cr对NiFe／PtMn双层膜交换偏置体系的磁性能及与微结构之间的关系。

Cd〓 may not be preconcentrated at PanY/ZMEs at open circuit and can be done at constant potential, show the ion-exchanged reaction between zeolite and surrounding electrolyte can not occur.

以PanY/ZME为工作电极用阳极溶出法测Cd〓时发现，在开路下不能富集Cd〓，只有通过阴极恒电位富集后，PanY/ZME对溶液中Cd〓才有响应，说明在PanY/ZME中不存在分子筛点位上的阳离子和溶液中阳离子的离子交换。

Flu viruses mutate constantly, which is why the flu vaccine is changed every year, and they can swap DNA in a process called reassortment.

流感病毒一直在变异，同时流感疫苗也每年在变。不同流感病毒的DNA能在重配的过程中交换。

Megaco/H.248 is an emerging standard that will enable voice, fax and multimedia calls to be witched between the public switched telephone network and emerging IP networks.

megaco/h.248是一个新出现的标准，能使语音、传真和多媒体呼叫在公共电话交换网和新出现的ip 网之间进行交换。

Now I offer to help by countering with something Id like help on in return.

In a word, WBAER can effectively remove micro-quantity HMI from DK with alkali metals, alkaline-earth metals and anions at high concentration.

最后得出结论：应用弱碱性阴离子交换树脂能在碱金属、碱土金属离子以及阴离子相对较高浓度的背景下有效地去除饮用水中的微量重金属离子。

During my break times, I would bring back to mind that beam of light which penetrated into our computer case on that special day.
