与sheathless相关的网络例句 [注：此内容来源于网络，仅供参考]

Of creatures that can fly and are bloodless some are coleopterous or sheath-winged, for they have their wings in a sheath or shard, like the cockchafer and the dung-beetle; others are sheathless, and of these latter some are dipterous and some tetrapterous: tetrapterous, such as are comparatively large or have their stings in the tail, dipterous, such as are comparatively small or have their stings in front.

一些能飞并且无血的动物是鞘翅类动物，因为它们把翅膀藏在鞘中，像是金龟子和蜣螂；一些是无鞘的，后面一类中一些是双翅的，一些是四翅的：四翅的，就像是那些相对较大的，或者刺在尾部的；双翅的，就像是相对较小的，或者刺在前方的。

Thus, in the last part of thesis, functionalized nanoparticles that are capable of selectively concentrating calcium ions from complex samples were employed for the sample treatment prior to electrodeless/sheathless ESI MS analysis.

本论文最后一部份是设计了一个实验，利用具有功能性的磁性铁奈米粒子先专一浓缩分离样品中的目标物-钙离子，再配合本论文中所设计的无鞘流界面进行电喷洒质谱分析。

In conclusion, the sheathless interface presented herein is easy to be fabricated. Furthermore, it has a comparable sensitivity with the conventional one.

本论文所提出之界面设计相当简单且容易制作，并和一般无鞘流界面的效果相同，可达到高灵敏度的分析结果。

Generally, electric-conductivity materials such as metal, conductive polymers, and graphite are coated on the outside surface of the capillary tip followed by the application of an external high voltage on the tip to provide a sufficient electric field to generate electrospray in seathless interface. Thus, the fabrication of the electric-conductivity material on the surface of fused-silica is one of the main issues when using sheathless interfaces.

一般来说通常需要将金属、导电高分子、或石墨等导电材料涂布於毛细管样品出口尖端，外加第二组电压於导电尖端以提供电喷洒时所需要的电场，但如何将导电材料稳定地涂布於矽氧材质的尖端表面一直是此界面探讨的主题之一。

In this thesis, a pulled bare capillary tip was proposed to be used as the ESI emitter. The outside surface of the tip was neither coated with electric-conductivity materials nor subjected to an external high voltage. Thus, there is no concern such as short lifetime that generally observed in conventional sheathless tips.

本论文尝试直接利用高温拉制及氢氟酸处理过的毛细管尖端做为电喷洒尖端，此设计不需要涂布导电材料及施加第二组电压於毛细管尖端处，此无鞘流界面因此能够避免因导电材料涂布不密合稳定而造成的易脱落及寿命短等问题。
