However, capital is managed still be in in our country start level, still exist on theory and practice a variety of errors:(1 ) go up in capital management guiding ideology, in thinking state-owned company assets recombines to trade with property right, appear " the pony pulls cart " the phenomenon can cause state-owned property prediction of a person's luck in a given year;(2) in process of executive capital dilate, corrupt big picture is fast, ignore the immanent quality that capital manages;(3) cut apart capital manages the immanent connection that manages with production, inspect capital to manage what manage at production for free more advanced management form;(4) manage capital regard as escape of debt useless debt " shortcut ", ignore capital structure optimize.

然而，资本经营在我国尚处于起步阶段，在理论与实践上还存在种种误区：（1）在资本经营指导思想上，认为国有企业资产重组与产权交易中出现的"小马拉大车"现象会导致国有资产流失；（2）在实施资本扩张过程中，贪大图快，忽视资本经营的内在质量；（3）割裂资本经营与生产经营的内在联系，视资本经营为游离于生产经营的更为高级的经营形式；（4）把资本经营当成逃债废债的"捷径"，忽视资本结构的优化。

In this paper, taking one 1900t/h supercritical pressure once—through boiler installed in East boiler company as subject investigated, analyzing the structure and characteristic of unit, from the mechanism of units, based on the law of quality conservation, energy conservation and momentum conservation, having Lagrange fluid particle tracing idea in hydrodynamics field application in analyzing of unit operational characteristic, author build up the nonlinear distributed parameter general dynamic mathematical model of single-phase heating surface or diphase heating surface in the steam-water system for supercritical pressure once—through boiler, which is suitable numerical calculation and simulation for large scale disturbance and full working conditions change, and enough materializing distributed characteristic of thermodynamic parameter in process and time lag characteristic of energy transportation in tache. The transient responses curve of the system main variables under several disturbance are computed by Computer Simulation for the model, and theoretical analysis shows that the simulation results are reasonable.

In this dissertation the"Penalty"finite element method was employed to compute the velocity of the three-dimensional flow of power-law fluid in a profile die. In order to decrease the needed computer memory and raise the stability of numerical simulation, a set of decoupled methods such as PFEM, pseudo-body force method and transformation of momentum equation to the elliptic equation was developed to establish the general finite element equations to compute the distributions of velocity and viscoelastic stress of the three-dimensional viscoelastic flow of the Phan ThienTanner fluid in a profile die. During numerical simulation of the extrudate swell of the PTT fluid, the flow in the die and out of the die was analyzed separately, which demands less computer memory. The key techniques used in numerical simulation of the three-dimensional extrusion from dies such as decision of boundary conditions, creation of initial velocity field, selection of penalty factor, high Weissenberg number problem , regeneration of the free surface were studied in detail.

Cluster initiatives are involved in a broad range of activities.In fact,two-thirds of allcluster initiatives surveyed had activities in at least five out of six broad activity areas(research/networking,policy lobbying,commercial cooperation,education/training,innovation/technology,and investment attraction).This seems consistent with a view ofcluster-based policy as a prioritization process across many different policies rather thanas new type of program focused only on,say,networking.Interestingly,we find thisbreadth in activities even in relatively young cluster initiatives.Cluster initiatives seem toincrease the intensity of their activities over time,not necessarily the number of parallel efforts.

集群举措，是涉及范围广泛的activities.in事实上，有三分之二的allcluster举措被调查活动中至少有 5个出六个广泛的活动领域（研究/网络，政策的游说，商业合作，教育/培训，创新/技术，并吸引投资），这样的说法似乎并不一致，以期ofcluster为基础的政策，作为一个优先次序的过程中遇到许多不同的政策，而不是thanas新类型的节目，只是集中，也就是说， networking.interestingly ，我们发现thisbreadth在活动，即使在相对年轻集群initiatives.cluster举措似乎toincrease强度，他们的活动随着时间的推移，并不一定数目的平行努力。
