For this design strategy to work properly (i.e., the rupture disk protecting the relief valve until the pressure reaches the disk's bursting point), the rupture disk must not leak or fail prior to the system pressure increase.

这样的设计能够很好的工作，前提是爆破片在系统压力增大之前不能泄露或者损坏（也就是说，在压力到达爆破片的爆破点之前，爆破片起到保护安全阀的作用），正常情况下，在爆破片爆破前，爆破片和安全阀之间处在大气压力下。

讨论了燃烧噪声的产生机理，分析了直喷式柴油机采用不同的预喷射策略，气体最高燃烧压力、最大压力升高率及气体高频压力振荡对燃烧噪声的影响。

As a college student,we also have our own"students' annoyances".

今天的学生至少有两种压力：经济压力和来自父母的压力。

Article 21 The manufacturing process of boilers, pressure vessels, pressure pipeline components, cranes and large entertainment facilities, and the installment, reform and major maintenance process of boilers, pressure vessels, elevators, cranes, passenger cableways and large entertainment facilities must be subject to the supervision and inspection carried out, according to the requirements of the safety technical code, by the inspection and testing institutions approved by the department of safety supervision under the State Council; the equipment may not leave the factory or be delivered for use until they have passed the supervision and inspection.

第二十一条锅炉、压力容器、压力管道元件、起重机械、大型游乐设施的制造过程和锅炉、压力容器、电梯、起重机械、客运索道、大型游乐设施的安装、改造、重大维修过程，必须经国务院特种设备安全监督管理部门核准的检验检测机构按照安全技术规范的要求进行监督检验；未经监督检验合格的不得出厂或者交付使用。

Because the major load bearing on retaining wall is soil pressure, the Coulombs theory of soil pressure, which is often used in engineering, is adopted to calculate the magnitude and the action point of soil pressure.

由于挡土墙所承受的主要荷载是土压力，因此采用工程中普遍使用的库仑土压力理论来计算土压力的大小和作用点。

Considering the progressive rupture mechanisms in backfill of different movement modes, the modified Coulombs solutions of active earth pressure were used to calculate the lateral earth pressures, the total lateral forces and their applied points. Comparisons of the calculated results with observations from model tests show that the prdposed methods can provide good predictions of earth pressures for different wall movement modes.

同时，根据不同位移模式下墙后填土渐进破坏的特点，对库仑土压力计算方法进行不同的修正，并引入摩擦角与位移之间的关系，得到不同墙体位移模式下任意位移时挡土墙上水平土压力强度大小、分布，水平土压力合力大小及合力作用点。
