The discovery of the Bainbridge reflex 70 years ago, of a tachycardic response to a rise in central venous pressure, stimulated a lot of interest in this and other cardiovascular reflexes.

Bainbridge reflex发现于70年前，指中心静脉压力的增高导致心动过速，当时引起了人们对此以及其他心脏血管反射的兴趣。

The central area or place of lowest barometric pressure within a storm.

在一次风暴中的中心区域或大气压力最小的区域。

The central area or point of lowest barometric pressure within a storm.

在一次风暴中的中心区域或大气压力最小的区域。

Housed at the third floor of The Bellevue Hotel, the spa's philosophy is to educate the guest in proper nutrition and stress management.

设在三楼的贝尔维尤酒店，水疗中心的宗旨是教育客户在适当的营养和压力管理。

, when the eccentricity is equal to zero, the arc centre of pad and the centre of axle journal are coincident, and the thickness of oil film is constantly C.

当偏心率为0时，如图5所示，瓦块圆弧中心与轴颈中心重合，油膜厚度恒为半径间隙，根据流体润滑理论，无动压效应，压力为0，瓦块摆角为零。

This displacement of air from the fan center to the circumference causes a reduced pressure at the fan center or inlet, I, towards which more air moves, to be thrown in turn to the circumference, thereby keeping up a continuous flow of air through the fan.

这种位移的空气从范中心到周长原因减少的压力，在樊中心或进气道，我，对更多的空中动作，被扔在谈一下围，从而保持了连续流动的空气通过风扇。

In-situ monitoring gave the following results: 1 a tension stress zone occurred at the bottom of reinforced rock mass which indicated that the role of rock bolting was remarkable; 2 stress concentration at surrounding rock of main shaft was gradually transferred from shaft wall to complete rock mass far from shaft center; 3 vertical displacement was gradually smaller from up to bottom and from center to outside of the reinforced loose rock mass.

首先，建立了主溜井三维有限元计算模型，模拟了主溜井围岩的塌落破坏过程和加固后的加固体的稳定性及变形特性；同时，还采用多点位移计等对加固体的稳定性进行了实地监测。计算结果表明：网棚锚注加固体的纵剖面上的压力和位移规律是①加固体下部局部出现拉应力区，表明锚杆的使用是合理的；②加固体内的应力由塌落中心向周围围岩过渡，应力越来越大，最终将荷载传至围岩中；③从下到上下沉逐渐减小；④从加固体中心到周围下沉位移逐渐减小，且近似一条抛物线。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
