多周期的

Experts pointed out that real estate development cycle is normally 2 to 3 years, this year to root, double the money supply shrink, projects to be reduced, but to go to from 2006 to 2007 will reflect the , and one two years ago started the housing project did not have much impact by regulation Mangshan downtime too.

专家指出，房地产开发周期一般是2至3年，今年的根源，双收缩货币供应，项目将减少，但到2006至2007年将反映，一两几年前开始的住房项目并没有产生多大影响的调控邙停工了。

Real estate development cycle is normally 2 to 3 years, this year to root, double the money supply shrink, projects to be reduced, but to go to from 2006 to 2007 will be reflected, and one housing project started two years ago did not have much control by the impact of downtime.

房地产开发周期一般是2至3年，今年的根源，双收缩货币供应，项目将减少，但到2006年至2007年将反映，一个住房项目开始两年以前没有太多的控制所产生的影响停机。

The multiple superpositional evolution of the Tarim basin is controlled by the wave prcesses of earth's crust, and the main cycles of these processes are 740～760Ma, 200～230Ma, 100～110Ma, 60～70Ma and 30Ma.

塔里木盆地的多期叠合发展受地壳波状运动的控制，控制塔里木盆地的主要周期有740～760Ma、200～230Ma、100～110Ma、60～70Ma、30Ma。

Therefore, borehole wall stability is systematically studied by applying multidiscipline, such as improving the basic theory of drilling geomechanics, precisely processing seismic profile, testing palaeomagnetic stress with core, computer simulation of equipotential surface of formation stress, and predicting stable period by core soaking.

为此，开展了系统研究工程，进行多学科、多角度的钻井井壁稳定性研究，即改进钻井地质力学的基本理论研究、精细化处理地震剖面图、岩心的古地磁应力测试、地层应力等势面的计算机模拟，井下岩心浸泡进行稳定周期预测等。

In chapter 4, sufficient conditions of at least one, two and multiple positive periodic solutions to a scalar functional differential equation with muti-finite delays are obtained by using a fixed point theorem introduced in [27] and [85] which is different from the one of a cone compression and expansion of norm type. It generalizes and improves some related results in the literature.

第四章利用文献[27]和[85]中所给出的不同于范数型锥压缩和拉伸的不动(来源：bc1cbcABC论文网www.abclunwen.com)点定理得到了具有有限时滞纯量泛函微分方程至少存在一个、两个和多个正周期解的充分条件，推广并改进了已有的相关结果。

The results show that under crop rotation of wheat and maize in damp soil and brown soil, stalks return to fields integrated with applying potash fertilizer can keep K balance within a cycle and K return rate reaches 109.1%～111.9%, annual wheat stalks return to fields can provide 226.5～261.0 kg/hm2 K, meanwhile the K return rate reaches 95.2%～97.1% for only applying potash fertilizer; under crop rotation of wheat and soy bean in grittiness black earth, only applying potash fertilizer can also keep K balance within a cycle, its K return rate reaches 119.9%, meanwhile the K return rate reaches 142.0% for stalks return to fields integrated with applying potash fertilizer, which result from maize being much more absorption to K than soy bean.

在砂姜黑土区小麦+大豆轮作制度下，即使小麦秸秆不还田，仅施用化学钾肥，亦能维持小麦-大豆轮作周期钾素的平衡。施钾配合秸秆还田处理，钾归还率达142.0%，施钾且秸秆不还田处理钾归还率达119.9%。主要是大豆不象玉米那样带走较多的钾造成的。

The numerical simulation demonstrates that when the intensity of the driving laser is over-saturated, the atom will be ionized rapidly during a few optical cycles, this will lead to a continuous multi-plateau structure in the cutoff region of the high harmonics spectrum from the neutral atom.

通过计算机数值模拟，发现当激光场的强度超过饱和光强时，原子将会在几个光周期内被迅速电离，使得原子的高次谐波谱在截止区呈现出平滑的多平台结构。

Together, these observations indicate that the reciprocal control of RNA silencing and the metazoan cell cycle impacts cellular behavior and disease.

综上所述，这些结论提示RNA沉默及多细胞动物细胞周期之间的相互调控影响细胞的行为及疾病的发生。

Using the generalized degree of A-proper mappings, the existence of periodic solutions for nonlinear vibration is established.

应用A-proper映象的广义拓扑度理论，对多自由度非线性振动系统周期解的存在性给出了严密的数学基础。

This is the nature of all kingdoms that are self sustaining; we know how to take care of ourselves and survive season after season; for our kingdoms could not have survived so many cycles of nuclear warfare of the human species if we did not know how to sustain ourselves on our own.

这就是所有自我维生的王国的天性：我们知道如何在季节交替中保护自己并一年年幸存下来；因为如果我们不懂得如何自我维生的话，我们也就无法从如此多人类核战争的周期后幸存下来。

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。
