The aim of this study was to develop a novel amphiphilic functional block poly(ε-caprolactone) bearing ketone groups MPEG-b-P(OPD-co-CL. 2-oxepane-1, 5-dione was copolymerized with ε-caprolatone in which methoxy poly (MPEG, Mn=5 000) and stannous octoate were used as initiator and catalyst, respectively. The syntheses were conducted by bulk and solution polymerization. 1H NMR results showed that peak position and splitting of the polymers synthesized through solution polymerization were consistent with theoretical data, demonstrating the products were designed block copolymers. While in the bulk polymerization, polymer peak position was changed due to their high reaction temperature, suggesting their structural variation.

将带有羰基官能团的4-羰基己内酯和ε-己内酯分别在甲氧基聚乙二醇(MPEG，Mn=5 000)为引发剂，异辛酸亚锡为催化剂溶液和本体体系中开环聚合，合成了两亲性侧基带有羰基官能团的聚己内酯嵌段共聚物MPEG-b-P(OPD-co-CL.1H NMR结果表明采用溶液聚合法合成的聚合物各峰的峰位置和分裂情况与理论一致，证明了产物是实验所设计的嵌段共聚物，而采用本体聚合法合成的聚合物由于温度的影响，聚合物各峰的峰位置发生了变化，说明其结构发生了变化；差示扫描量热法分析结果表明随着OPD单体含量的增加，聚合物的熔点，玻璃化转变温度和熔融焓增加；热失重测试结果表明OPD单体的引入增加了聚合物的热敏感性。

The OLM improves overhead crane and monorail positioning with exact absolute position information and eliminates overshooting targets, creeping into position, and re-zeroing that is standard for typical systems using rotary encoders and mechanical switches for positioning.

OLM运用精确的绝对位置技术来提高高架起重机和单轨铁路定位，以消除超出规定范围情况，缓慢进入位置并重新归零，这是使用旋转编码器和机械开关的典型定位系统的标准。

For the tetracene overlayer near to a monolayer, formation of a parquet-like pattern was observed.

当分子长轴取向垂直于[1-210]方向并且其质心位于密排原子列上两个Ru原子的短桥位时，该位置是它的次佳吸附位，在该位置的吸附能为4.19 eV。

The specific anatomic location of the lesion within the sacrum was also noted for each patient (anteroposterior plane: central, right paracentral, or left paracentral; sagittal plane: anterior or posterior).

每位患者都记录了病灶在骶骨内的特殊的解剖位置（冠状面：中央、右侧或左侧；矢状面：前或后）。9例病灶的位置和测量值见table 1。

BACKGROUND: With supraglottic airway devices, such as the laryngealtube suction, ProSeal laryngeal mask airway andCobra perilaryngeal airway, oropharyngeal leak pressureor cuff position may vary according to changes in the positionof the head and neck.

背景：在使用声门上气道装置时，例如：喉管吸引，胃管引流型喉罩，Cobra喉周通气道，口咽漏气压力和套囊位置会随着头颈位置的变化而变化。

The number and location of protein bands were different among these species. It was also obvious that the positions of the main protein bands in Blattella germarica were different from those in two Periplaneta species, and the positions of the main protein bands in female insect were different from those in male insect.

通过比较发现3种蜚蠊的蛋白质区带数目和位置有差别；德国小蠊主要蛋白质区带的位置与两种大蠊相差明显；♀♂之间也有差别。

Grinding the Glasscock triangle can expose the os petrosum segment of ICA,so ICA can be blocked.

磨开Glasscock三角可以暴露岩骨段颈内动脉，是实施颅内段阻断颈内动脉的位置，这个位置又可行颈内动脉海绵窦段的旷置和颈内动脉床突上段的搭桥。
