不变化的

This gleam of the sexual relationships existence, adds step-by-step electric motor characteristics such as only having the cyclicity error but there being no accumulative error.

在非超载的情况下，电机的转速、停止的位置只取决于脉冲信号的频率和脉冲数，而不受负载变化的影响，即给电机加一个脉冲信号，电机则转过一个步距角。

Let us be clear, we are not industry campaigners, we are not in the pay of a mythical aviation lobby and we do not belong to some clandestine network of climate change "deniers"– charges that will almost inevitably be levelled at us by members of the green movement.

让我们实话实说吧，我们并不是为了这个产业而游行的人，我们没有接受什么秘密的航天业的行贿，而且我们也不属于某些秘密的气候变化的&否认者&组织----这些几乎都不可避免地是那些绿色行动组织成员为我们标记的。

In fact,it is function of temperature and pressure especially for HTHP gas well.

以往的模型在确定气体参数时，很多情况下把井筒内的气体黏度认为是不变的，而实际上黏度是温度和压力的函数，尤其是在高压情况下，气体黏度在不同的井段是一个动态变化的量。

The range of evolutionary theories during "the eclipse of Darwinism" included forms of "saltationism" in which new species were thought to arise through "jumps" rather than gradual adaptation, forms of orthogenesis claiming that species had an inherent tendency to change in a particular direction, and forms of neo-Lamarckism in which inheritance of acquired characteristics led to progress.

在&达尔文主义衰落时期&，进化理论包括各种形式的&骤变说&，认为新种是通过&跳跃&而不是通过逐渐适应产生的；也包括各种形式的直生论，声称物种有着内在的、向某一特定方向变化的趋势；还包括各种形式的新拉马克主义，认为获得性状遗传导致进步。

Combustion technology. According to the character of CFB and current research, a steady state model of the flow structure and mixing process in the upper dilute zone of a CFB, where variations in flow parameters with height are neglected,揅ontinuous桪ispersion Model? is presented. The model is based on a two梡hase structure, consisting of an upflowing lean suspension and a downflowing particle clusters. On the basis of this model, a numerical simulation calculation model about flow structure and temperature field is established.

根据循环流化床锅炉特点及国内外的研究开发现状，本文在不考虑沿炉膛高度方向上流动参数变化的情况下，提出了一个描述循环流化床上部稀相区流动结构和混合过程的稳态模型——&连续扩散模型&，即认为床内存在着向上运动的气固悬浮相和低速下降的颗粒絮团相，在此基础上建立了流动结构与温度分布的数值模拟计算模型。

We saw the spiral as the organising element of the MUMUTH in much the same way as Serialism works in contemporary music; the continuous line absorbs and regulates intervals and interruptions, changes of direction and leaps of scale without losing its continuity.

我们看到的恶性循环作为举办的MUMUTH内容大致相同的方式序列的作品在当代音乐；不断线吸收和调节间隔和中断，变化的方向和飞跃的规模而不失去其连续性。

It also shows that the degree of employees'engaging in influence activity can depend on the expectation of the distribution of"quasi rents"created by strategic change.

模型表明：影响活动对战略转换会产生有害的障碍，而且影响成本与企业前景正相关；惯性的一个来源是组织不愿意承担变化的影响成本；员工施加影响活动所达到的程度依赖于员工对战略转换所造成的&准租&分配的预期。

An explicit analytical solution of the threshold pump power of the laser has been derived based on rate equations which contain the attenuation coefficients of the pump and laser radiations as well as the major contribution of the re-emission of the upper level atoms to the pump wave by using the analytical solutions. An analytical solution of the minimum fiber length required for the onset of the oscillation is presented. In addition, the analytical solutions describing the variations of the density of the pump radiation and upper laser level population along the fiber length have also been given.

从速率方程组出发，在不忽略光纤损耗系数和保留再发射项主导部分的近似条件下推导出了双包层光纤激光器阈值泵浦功率的显函数解析表达式，得到了光纤激光器产生振荡所需的最小光纤长度的显函数解析解；还给出了泵浦光子数密度和上能级粒子数密度沿光纤方向随光纤长度变化的显函数解析解。

In the present work, we have done the following modifications: the finite range Gogny force has been used where the pairing correlation can be considered self-consistently, no symmetry restriction has been imposed where the triaxial and higher multipole deformations can be discussed, no approximation for Hartree-Fock and pairing fields has been done where all the contributions from Gogny force, Coulomb force and the center of mass correction to Hatree-Fock and pairing fields have been included.

Sakata等人首先提出组态指定的参考态方法，并在具有轴对称和旋称对称性的Skyrme-Hartree-Fock平均场中实现了这种新的微观描述，自洽地给出具有不同组态的激发态及随原子核转动频率或形变连续变化的平均场。

Based on the efficient approach developed above, cases of foundationinhomogeneity with stiffness varying according to an exponential function along the radialdirection, and cases of foundation inhomogeneity with stiffness discontinuity and with weakinterlayer strata on the earthquake response of concrete arch dams as well as gravity damswere analyzed. It is found that taking into account the effect of foundation inhomegeneity forthe earthquake safety assessment of concrete arch and gravity dams has great significance.

在以上理论的基础上，本文充分利用比例边界有限元法能够模拟非均匀无限域的优点，合理地提出了重力坝、拱坝的非均匀无限地基模型，分别研究了地基材料弹性模量沿深度按指数变化的无限不均匀地基和地基中存在断层或软弱夹层时对重力坝和拱坝的地震响应影响。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
