绘制庞加莱截面图 在相空间中适当（要有利于观察系统的运动特征和变化，如截面不能与轨线相切，更不能包含轨线）选取一截面，在此截面上某一对共轭变量如x1和x.1取固定值，称此截面为Poincare截面，相空间的连续轨迹与Poincare截面的交点成为截点。(Poincare mapping sections in the phase space properly (should be beneficial to observe the system and changes in movement characteristics, such as the cross-section can not be tangent trajectory, but also can not contain rail line) to select a cross-section, in this section for a total of conjugate variables, such as x1 and X.1 take a fixed value, call this cross-section for the Poincare section, the phase space of the continuous trajectory of the point of intersection with the Poincare cross-section to become cut-off point.)

使用虚拟处理器的SPMD 并行程序，我将介绍使用虚拟处理器的一些结果 技术，并行计算程序的一些SPMD。 “ 测试的技术真正的处理器是英特尔超线程， 和程序，浮点计算的MATLAB脚本。 工作的关注实用和限制的结论 使用的方法。主要结果是，使用虚拟处理器 不仅为改善并行程序是一个很好的技术 基于内存的计算，但在大量的磁盘存储的情况下 操作太多。 (Using virtual processors for SPMD parallel programs，I describe some results on the use of virtual processors technology for parallelize some SPMD computational programs. The tested technology is the INTEL Hyper Threading on real processors, and the programs are MATLAB scripts for floating points computation. The conclusions of the work concern on the utility and limits of the used approach. The main result is that using virtual processors is a good technique for improving parallel programs not only for memory-based computations, but in the case of massive disk-storage operations too)

Turbo Pump - TP The technology of cryogenic liquid is extremely delicate because of low operating temperature (90 K for liquid oxygen and 20 K for hydrogen) and also for their particular chemical and physical properties.
