假定

According to penetration mechanism of jacked pile, the expansion of a series of spherical cavities in semi-infinite space is used to simulate the process of pile installation; and soil is assumed as Mohr-Coulomb material.

根据静压桩的贯入机制，将沉桩过程模拟为半无限土体中一系列球形孔的连续扩张，土体假定为Mohr-Coulomb材料。

By replacing the fifth postulate in the preceding paper with the condition of spherical symmetry of space we again obtain the Friedmann universe in relativistic cosmology.

将前文中第五个假定改为"空间具球面的对称性"后我们仍遵出费烈特猛宇宙。

Over break 3. But even assuming that a planet is the right size and has the proper chemical composition and a stable orbit neither too far from its star nor too close, so that its temperature is at all times in the range of liquid water (as is true of Earth except for the polar regions), a great deal would stilldepend on the kind of star it was revolving about.

over break 但是即使假定有一颗行星，它的大小正好，化学成分适宜，运行轨道稳定，与恒星的距离既不太远也不太近，气温始终保持在液态水温的范围内（正如地球上极地以外地区的温度一样），那儿是否存在生命，在很大程度上仍得取决于它所围绕运转的是什么样的恒星。

Since the investigations of Stade and Wellhausen, such changes have been assumed in increasing proportions.

由于调查比赛和浩，这种变化已被假定在增加的比例。

Let the road excitation be a stationary random process with zero mean.

假定路面扰动是均值为零的平稳高斯随机过程。

However, almost all the current theories for climate prediction, including the ones in statistics and nonlinear science, are based on assumption that the process is stationary which is contrary to the nature of the climate process.

在大气运动中，气候正是一个典型的非平稳系统，但是现有的气候预测理论，包括统计预测理论和非线性预测理论，几乎都无一例外地建立在平稳性假定的基础之上，这有悖于气候过程的基本性质，因此它有可能是导致气候预测水平低下的重要的理论原因。

As to the assumption of stationary state,...

我们讨论了热、光和催化剂分解引发的加聚反应动力学，结合自由基型加聚反应的特性，得到了动力学方程粗的解，推导出链段分布和平均分子量公式，证实稳定态假定对于自由基型加聚反应是可以应用的。

Traditional structural damage detection research based on the vibration mostly supposes that the system is in stationary state before and after damage so dynamic properties of the structure can be compared.

由于时程数据处理方法上的缺陷，传统上基于振动的结构损伤分辨的研究大多都是假定系统在损伤前后为线性的前提下，通过比较系统在损伤前后的系统特性来进行损伤检测。

The drawing actually shows the drum H containing the one-way clutches, rather than the steam cylinder, which was presumably unchanged.

绘图，其实显示鼓h载一程离合器，而非蒸汽汽缸，这是假定不变。

Such as axial compression coefficient and stirrup ratio, which affect ductility of the columns, are researched.

首先基于一定的基本假定，通过计算给出了十字形配钢的钢骨高强混凝土柱的轴压力系数限值。

And discuss some key point of integrated management system design, include hazard identification and risk assessment and risk control in the occupational health and safety management, the measure of satisfaction target of customer, the flawlessness of law system, the integration of the integrated management system and enterprise standardization system, unify lead institution and work orgnization, integreted internal audit and integrated management review.

同时，论述了一体化管理体系构建中的几个主要问题，包括职业健康安全管理中的危险源辨识、风险评价和风险控制、顾客满意度的科学监测、法律、法规体系的完善、一体化管理体系与企业标准化体系的有机结合、统一的领导机构和工作机构、一体化的内部审核和管理评审。
