摘要〗采用超高效液相色谱-电喷雾二级质谱联用技术同时测定水中7种抗生素，优化了试验条件。磺胺甲恶唑、诺氟沙星、环丙沙星、氧氟沙星、四环素在1.00 ng/L ～1 000 ng/L 范围内线性良好，定量下限为1 ng/L ，土霉素、金霉素在10.0 ng/L ～2 000 ng/L 范围内线性良好，定量下限为10 ng/L ，去离子水和地表水样加标回收率为72.1%～112%， RSD 为0.6%～9.2%。

In order to understand the adaptation of the microorganisms under the extreme cold environment conditions, the physiological characteristics of the 5 bacterial isolates from the Muztag Am ice core under the different temperatures were investigated. The csp gene was also amplified by PCR technique and the specific primer targeted for the cold shock protein. The observation results showed that there were three phenotypes of microorganisms: psychrophiles growing from 0~23°С(the optimum temperature at 15°C), psychrotolerant with growth range at 0~40°C (the optimum temperature at 23°С), and the thermophile with growth range at 0~45°C(the optimum temperature at 30°C).

为了解冰川微生物的生理生长特征及其在极端寒冷环境条件下的冷适应特性，从慕士塔格冰芯分离菌株中选取了5个代表菌株，分别对这些菌株的生长温度和酸度范围进行了观测，并利用微生物冷诱导蛋白的保守氨基酸序列，设计了1对冷诱导基因csp的特异引物，并对其进行了PCR扩增。

In the temperature range between 15 oC and 25 oC, the plateau height increases with increasing temperature. However, in the temperature range between 33 oC and 45 oC, the plateau height decreases with increasing temperature. The results reveal that additional chemical reactions other than the enantiomerization of thioridazine are involved.

在15 oC~25 oC间，平台的高度随温度增加而上升，但在27 oC~33 oC间平台的高度已不再增加，甚至在33 oC以后，平台的高度反而随著温度的上升而下降，此现象显示分析物的对掌异构转换过程中，会随著温度的升高而涉及其他化学反应的参与。

In noise-exposed ears, the occurrence of threshold changes in the high frequency range (10 to 20 kHz) is earlier than that in the low frequency range (0.5 to 6 kHz).

接触噪声的各年龄组10～18 kHz阈值随年龄的增长而升高；不同工龄组比较，6～10年工龄组的10～18 kHz阈值明显升高；不同噪声强度组的10～20 kHz阈值比较差异无显著性（P＞0.05）。

Introduced in 2006, the Land Rover Range Rover Sport combined the sophisticated looks of the top-dog Range Rover with the body-on-frame platform of the LR3 at a price that split the difference between the two.

介绍了在2006年，路虎揽胜运动相结合的先进期待的顶级揽胜狗的身体上帧平台LR3的价格分裂两者之间的差额。

The influence of the defect on the torsional stiffness and the stress distribution are calculated and analyzed by finite element method. The defect widths range from one-tenth of the femur outer diameter(0.1D) to (0.3D), and defect lengths range from 1D to 5D.

计算结果表明：骨缺损长度为D时，对股骨扭转刚度和剪应力分布的影响较小；骨缺损长度从2D增至4D时扭转刚度急剧减小，而且剪应力的最大值位于骨缺损中心。

Some people have noticed that the 'assigned' lines in the status plots sometimes move downwards between updates -- if you look at the 5 trillionth bit range now, you'll see that there was a range just recently assigned, even though a week ago, it showed that it was 100% assigned.

有些人已注意到，状态区域中的已分配线有时会在两次更新间下降-如果你关注第5百万比特范围，你将发现有部分范围刚被分配，即使一个星期前它显示已100%分配完。

When this condition occurs, inbound replication with the source partner is stopped on the destination domain controller and event ID 2042 is logged in the Directory Services event log.
