Blood pressure monitoring has come a long way from the initial observations made by Reverend Hales in the 18th century. There are none that deny the importance of monitoring perioperative blood pressure; however, the limited ability of the current prevalent technology (oscillometric blood pressure monitoring) to offer continuous blood pressure measurements leaves room for improvement. Invasive monitoring is able to detect beat-to-beat blood pressure measurement, but the risks inherent to the procedure make it unsuitable for routine use except when this risk is outweighed by the benefits. This review focuses on the discoveries which have led up to the current blood pressure monitoring technologies, and especially the creation of those offering non-invasive but continuous blood pressure monitoring capabilities, including their methods of measurement and limitations.

许多化学过程都要在高压下进行,因为高压状态能提高产率,加快化学反应的速率,分离过程中提高溶剂功率,并通过增加分子能量和分子碰撞率来克服活化作用的障碍。通过金刚石砧室压力能高达数百万巴,实验室就能达到这种效果,因此为利用热力学、输运和电子性质来进行化学合成以及合成新材料提供了新的途径。然而,在工业规模上,高压工艺目前正受到压缩成本和有限材料的约束,因此很少有工业过程能够在在压力超过25 MPa的情况下进行。本文提出了一种高压工艺的替代方法,即利用来自固体底物的表面驱动的相互作用产生非常高的局部压力。近期的实验和分子模拟表明,这种相互作用可以产生高达数万巴的局部压力,某些情况下甚至可以达到数百万巴。由于活跃的高压区域分布不均匀,压力在不同方向上存在差异。在许多情况下,增强最多的是平行于底物表面的压力(切向压力)。这种压力是施加在要加工的分子上的,而不是施加在固体底物或容器上。本文综述了现阶段对这种增压的认识,并讨论了一种基于表面驱动力的可行方法来达到高压处理的效果。这种表面驱动高压处理的优点在于,相比传统的整体相位处理,它能达到更高的压力,因为它不需要机械压缩。此外,过程中没有对容器施加更大的压力,因此不用担心材料受损。

Hydraulic thrust system is an important system in a shield tunneling machine. Pressure regulation of thrust cylinders is the most important function for thrust system during tunnel excavation. In this paper, a hydraulic thrust system is explained, and a corresponding simulation model is carried out in order to study the system characteristics. Pressure regulation of a certain group’s cylinders has little influence on regulation of the other groups’ cylinders. The influence will not affect the process much during tunnel excavation. Pump displacement may have a greater effect on pressure regulation and oil supply flow rate should be adaptive to the system’s demand. A exacting situation is simulated to explain how pressure regulation works during tunnel excavation.
