查询词典 nucleus

Active MAPKs translocate into nucleus and thus regulate gene expression. Now, three main parallel pathways of MAPK family have been discovered : ERK1/2, JNK and p38. They can induce different gene expression and thus cause different cell reaction.

现已发现MAPK家族主要有三条平行的信号转导通路：ERK1／2、JNK和p38，三条通路可以活化不同的转录因子，启动不同的基因表达，从而引发不同的细胞反应。

Blasting out from the active galactic nucleus toward the upper left, the energetic jet extends about 13,000 light-years.

高能喷流从活动星系核喷向影像左上方，一直延长大约有1.3万光年远。

Other observations have revealed that NGC 4945 has an active galactic nucleus, meaning its central bulge emits far more energy than calmer galaxies like the Milky Way.

其他的观测资料显示， NGC4945拥有一个活动星系核，这意味着：跟象银河系这样比较平静的星系相比，其中心的凸出区域所释放的能量要多得多。

After water treated by LVEF, the scaling ions in the water will be transformed into active fine crystal nucleus which scattering in the treated water by the electric field. These crystal nucleuses have lower surface energy and greater active surface area.

水经低压电场处理后，水中成垢离子会优先在电场中析出并形成活性微晶核分散在处理水中，这些微晶核具有较高的表面能和较大的活性表面，它们更容易吸引水中的成垢离子，从而阻止在换热表面形成垢核并继续长大，从而达到阻垢的目的。

Blazars are one of the most extreme classes of active galactic nucleus, with high luminosity, large amplitude and rapid variability, high and variable polarization, radio core-dominance, and apparent superluminal speeds. Their broad band emission extends from radio up to gamma-ray band, and is dominated by non-thermal process.

中文摘要：在AGNs中，Blazar天体是具有极端性质的一类，它以大幅快速光变、高且变化的偏振、射电核主导、视超光速运动、全波段非热辐射为主要特征。

Alternatively, the spectral softening above 2 GeV could be due to gamma-ray absorption via photon-photon pair production on the soft X-ray photon field of the host active galactic nucleus, but such an interpretation would require the dissipation region to be located very close (l~100 gravitational radii) to the black hole, which would be inconsistent with the X-ray spectrum of the source.

另外的关于2 GeV以上能谱变软的可能解释是高能光子和寄主活动星系核的软X射线辐射场通过电子对产生反应而被吸收，但是这个解释要求反应区域要很靠近中心黑洞(1~100倍引力半径)，这和3C 454.3的X射线测量谱相矛盾。

在活动星系核中，Blazar天体是具有极端性质的一类，它以大幅快速光变、高且变化的偏振、射电核主导、视超光速运动、全波段非热辐射为主要特征。

The whole new-formed nucleus also migrated to the other side of the adjacent cell.

本研究直接证明了穿壁现象的真实性。

Objective To observe the role of nucleus raphe magnus in analgesia produced by the activation of muscle spindle afferent.

目的 观察中缝大核在肌梭传入镇痛中的作用。

The afferent connections of GC also indicate that this nucleus is closely related to motor activity.

LC腹侧部至PGCL的传入可能是产生PS过程中肌肉驰缓的解剖学基础。

I will endeavour to find you some assistance.

我尽力帮你找人帮忙。

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
