The phase of optical wave can be recovered by the intensity transport equation under the paraxial approximation For the optical system with diffraction limit, it is difficult to get the boundary radical slope of phase and sample in the circular domain boundary when using the intensity transport equation to recover the phase, consequently, we reviewed an algorithm mentioned in the reference ［4］, namely, the equation, computation domain and boundary condition are changed, then the phase is reconstructed by the multigrid method and corrected at last Moreover, the experiment system is set to testify the algorithm, and the recovered phase from the intensity data detected by CCD is compared with the result from phase retrieval algorithm, it is found that the phase reconstruction error can reach 017 λ in the case of non-uniform intensity distribution, as a result, the method is suitable for the phase recovery with low wavefront sensing accuracy.

在傍轴近似条件下，可以利用光强传播方程对畸变波前进行相位恢复。对于衍射受限的光学系统，很难获得相位的边界径向斜率值作为边界条件，此外，要获得精确的圆域边界采样值也并非易事。为了克服上述困难，进一步研究了相位恢复改进方法，即改变了方程的表示形式、计算区域和边界条件，并用多重网格法进行求解获得重构相位，最后再将其修正。为了验证算法的精确性，搭建了实验系统对算法进行实验验证，将由CCD探测的光强分布进行计算得到的相位分布与相位恢复算法的结果进行比较，证明在光强分布非均匀的情况下，该方法恢复的相位均方根误差能够达到017 λ，可以适用于波前传感精度要求不是很高的相位恢复。标签自适应光学相位恢复相位修正光强传播方程 adaptive optics phase retrieval phase correction intensity transport equation

In this paper, a series of lunar map projection formulas are deduced including azimuthal projections, cylindrical projections and conical projections. The lunar map projections software is compiled. By caculating lunar map projection distortions, their projection distortion rules are found. Base on the lunar exploration mission, the lunar map projection scheme is given in this paper. The azimuthal conformal projection or the circumcenter perspective azimuthal projection is usually used in small areas, especially in two poles. When the whole map of the moon is needed, the azimuthal conformal projection or the circumcenter perspective azimuthal projection is used within 10° in the poles, and the traverse tangent cylindrical conformal projection or the normal secant conical conformal projection can be used in else areas, furthermore, band-division is necessary to reduce the projection distortion.

It is learned that China's commercial real estate development there are still a number of shortcomings, one of which is the development of the concept of the blind, and some commercial real estate development companies inaccurate positioning of the project, the development of the commercial format is not clear, there is no sequence, such as investment management plan, which led to the development of real estate projects follow-up can not keep up; Second, the existing part of the commercial real estate development enterprises are engaged in housing construction origin, the former in order to sell an end in itself, is an obvious short-term business; while the latter is obtained through the lease operators for the purpose of long-term returns, the differences between the two was not by a clear understanding of corporate decision-makers, at the same time affected the design and planning until the latter part of the management and many other links.

据了解，中国的商业房地产的发展仍然存在着一些缺点，其中之一是发展的概念的盲人，和一些商业性房地产开发公司的定位不准确的项目，发展商业形式目前尚不清楚，也没有序列，如投资管理计划，这导致房地产开发项目的后续行动跟不上，二是现有的部分商业房地产开发企业从事住宅建设出身，前者以销售本身就是一个目标，是一个明显的短期业务；而后者则是通过租赁运营商的目的是长期回报，两国之间的分歧不是由一个清楚地了解企业的决策者，同时影响了设计和规划直至后期的管理和许多其它联系。

The experiment results showed that:in acid pickling process, when reaction temperature is 100℃, the leaching time is 2.5h, mixing speed is 400r/min, the sulfuric acid density of solution is 45% and excess coefficient of sulfuric acid is 1.5, recovery rate of iron from hematite is 82.3%.

Statistic analysis result shows that the time step is the most important influence factor of simulation precision, and there is relation between simulation error and the setup value of restitution coefficient which the greater the setup value is, the less the simulation error is. Although there is no effect to the total contact time in the course of collision, the value of the time step decides the total contact step, and there is a logarithmic linear correlativity between them.

统计分析结果表明：计算时步是影响模拟精度最重要的因素；模拟误差还同恢复系数的设定值有关，设定值越大，模拟误差就越小；计算时步的大小虽然对碰撞过程的总接触时间影响不大，但是却决定了碰撞过程的总接触时步数，二者之间存在对数线性相关关系

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
