周质的

In closed stable stomatal guard cell, long filaments randomly distributed in cortex.

在关闭的气孔保卫细胞中，较长的微丝散乱分布在整个周质区域。

By using a soil modeling of three axes symmetry and considering three dimensions wave effect ,the longitudinal vibration characterisitic is analyzed on condition that a vertical force being harmonious and stimulating force is loaded upon the whole newel stake in the damping soil of homogeneous and detained material.

从三维轴对称土模型出发，考虑桩周土体的三维波动效应，对均质滞回材料阻尼土中完整端承桩在垂直协和激振力作用下的纵向振动特性进行分析，求解得到桩顶频域响应解析解、复刚度和速度导纳，利用卷积定理和傅里叶逆变换，求得半正弦脉冲激振力作用下桩顶速度导纳时域响应半解析解。

Finally we studied the secretion expression of TGF β1 mature peptide gene in the periplasm and extracellular medium respectively.

在胞内表达TGFβ1基因的同时，还研究了TGFβ1基因在周质和胞外培养基中的分泌表达。

When protein folding is compromised in the periplasm of E.

当大肠杆菌E.coli周质中蛋白折叠发生阻碍，外膜蛋白OMPs的C端与三聚体DegS蛋白酶的 PDZ区域发生结合，促使ResA裂解。

ELISA and MTT assay show that coexpression of 〓 gene and dsbA gene, can increase the total content of TGF β1 in the periplasm, and gain biological activities.

而ELISA测定和MTT测活都表明，共表达〓和dsbA基因，使得周质中TGFβ1的含量明显增高，并具有显著的生物学活性。

Coli. Transmission electron microscopy was used to evaluate the cell morphology of both the normal and the treated E. coli. The observation with TEM suggested that silver nanoparticles lead to the formation of "pits" in cell wall of the bacteria, and silver nanoparticles could enter into periplasm through the pits and destroyed the cell membrane.

采用透射电镜观察了经纳米银粒子处理过的大肠杆菌细胞形态变化过程，结果显示纳米银粒子先在细胞壁上产生小的孔洞，通过这些孔洞进入周质空间，导致细胞膜成分渗漏和破坏细胞膜，进而进入细胞内部。

Coil and B. subtilis using the β-lactamase distribution assay. The results showed that the β-lactamase activities of E.coli are mainly in periplasm while the enzyme produced by B.

内酰胺酶活力测定表明，大肠杆菌产生的酶主要积累在周质空间，而枯草芽孢杆菌产生的酶主要分泌在胞外。

Western blotting confirmed that the low activity of b-lactamase in E. coli Top10 pcs+ resulted from a lower amount of b-lactamase in its periplasm.

由此可见，周质内低含量的b-内酰胺酶是导致E.coli Top10 pcs+细菌氨苄青霉素抗性降低的原因。

It shows that coexpression of secE/Y gene can increase a new band of about 25kD in the periplasm, but further electrophoresis analysis and Western blot prove that this band may not be the assembled TGF β1 dimer.

发现共表达secE／Y基因可使周质中新增25KD的蛋白带。

I would rather be ashes than dust! I would rather that my spark should burn out in a brilliant blaze than it should be stifled by dry-rot.

我从来不相信英文可以在几周之内有质的提高，但是刚上大学时我还是买了很多期《疯狂英语》，原因是那几期真的很&正点&！

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
