The intensity of pressure is the most markable factor that influence the casts mechanical properties and microstructure. When its value exceeds 40MPa, the disfigurement such as shrinkage porosity can be effectively reduced . when its value exceeds 120MPa, the pressure obviously influence the crystal performances of liquid metal also, and compact homogeneous exiguous equiaxial crystal can be obtained. Pressure can also increase the solubility of Cu in a -Al.

The surgery of female stress urinary incontinence has more ways,but it is essentially around two main themes:First,extense urethra,narrow urethra cavity diameter,increase urethral wall tension; Second,improve the bladder neck location,restore bladder urethra horn,recover the pressure transfer to urethra side when abdominal pressure increases,thus increase the urethral atresia pressure and length of the urethra,reach the aim to control incontinence.

女性压力性尿失禁手术治疗的方法较多，但本质上主要围绕两个主题进行：一是延长尿道，缩小尿道腔径，增加尿道壁张力；二是提高膀胱颈位置，恢复膀胱尿道后角，恢复增加腹压时压力向尿道侧的传递，从而增加尿道闭锁压及机能尿道长度，以达控制尿失禁的目的。

Indeed, by increasing the pressure in the right atrium and in the left ventricle with respect to extrathoracic vascular beds, positive-pressure ventilation affects the pressure gradients for both systemic venous return and left-ventricular ejection increase; Fig.

实际上，机械正压通气引起的右心房、左心室内的压力增加，这样和胸腔外血管床形成一定的压力梯度，此压力梯度会影响心肺两系统的静脉回流及左心射血（增加，见图1）。

The results show that the air crossing pressure pulse magnitude of the container generated in the tunnel is 3.46 times that generated in open air when container flat wagon at the speed of 160 km/h passed by EMU moving at the same speed. Both the lateral force and overturning moment of the container train during the crossing induced in open air and tunnel are approximately proportional to the square of running speed of the passing train. The pressure of crossing side and uncrossing side for the container flat wagon is almost equal since the one-dimensional characteristic of pressure distributing induced in the tunnel is not faintish. Consequently, the value of the lateral force and overturning moment of the container train generated in open air is greater than that generated in the tunnel, about 1.1 times.

研究结果表明：集装箱平车以160 km/h的速度与动车组等速交会时，在隧道内会车时车载集装箱中部压力变化幅值是在明线会车时的3.46倍；在明线和隧道内会车时，集装箱列车受到的侧向力和侧滚力矩均与交会列车运行速度近似成平方关系；因隧道内压力分布一维特性较强，集装箱平车交会侧与非交会侧压力相差并不大，因此，在明线会车时集装箱平车受到的侧向力和侧滚力矩均比隧道会车时的大，大约是其1.1倍。
