Due to the problems existing in simulation on physical model of fire, such as heavy calculation, high complexity and difficulty in real-time simulation, a new real-time simulation method was raised based on fluid model and GPU acceleration. This method, based on the physical characteristics of fire, such as incompressibility, low density and inviscid, used the fluid equations to calculate the properties of fire. Then by accelerating this method through GPU, the real-time simulation of fire was realized and a realistic effect was achieved.

Writing sparks inspirationally, need a few pretext to make you produce writing theme, this composes clew namely, settlement way, it is static the paper face books that next hearts will come to read the static state such as newspaper and magazine more, because read rate very slow, your reflection ability was occupied windward, the characteristic of newspaper and magazine is to have many hurdle race content, all over the country of it may be said, all kinds of strange things, whats have, you can see the most primitive antique china all the time from the popular mobile phone of newest money, you can see from cosmic aerospace all the time domestic cate, you also can see from economic crisis movie and TV stars all the time, function of a kind of opinion of a kind of a few incident, comment, product introduces, draw the writing inspiration that removes you possibly.

二、写作灵感的触发，需要一些由头来使你产生写作主题，这也就是写作线索，解决的办法，是静下心来多阅读报纸和杂志等静态的纸面读物，由于阅读速度很慢，你的思考能力就占了上风，报纸和杂志的特点是拥有大量的跨栏内容，可谓天南海北、千奇百怪，什么都有，你可以从最新款的流行手机一直看到最原始的古董瓷器，你可以从宇宙太空看到一直家庭美食，你也可以从经济危机一直看到影视明星，一些事件、一种评论意见、一种产品功能介绍，都可能勾起你的写作灵感。

Forty operative cases were randomly divided into the retroperitoneoscopic group and the laparoscope group. All cases were applied general anesthesia, and hemodynamics of 30 minutes after CO2 insufflation, arterial blood gas, time of operation, time of anus purge gas and time of hospitalization were measured.

This paper gives the time domain integral constraints of the feedback control systems tracking error that arise from the presence of stable zeros on or near the jω-axis, which shows that for a linear time invariant system, in order to guarantee the stability of the closed-loop system, the time domain integral constraints must be satisfied by the tracking error.

In the computation of aerodynamic forces, the present work is based on the work of Morino et al., but the following aspects are improved:(1) In computing the steady transonic aerodynamic load, the steady transonic nonlinear integral equation is solved by relaxation-iteration method in this thesis, instead of solving the time dependent transonic nonlinear integral equation, so that the computing time is saved greatly;(2) The influence coeifficients represented by volume integral are transformed to surface integral by using the Gaussian Theorem, so the analytical form of these coeifficients can be obtained and this leads to be more convenient to analyse and compile computer program;(3) The shock capturing method is used in every time step in present work, no shock moving term is added in the integral equation, so that it is more convenient and simpler to treat.

在气动力计算方面，本文基于Morino等人的工作，作了如下几方面的改进：（1）在计算定常跨音速流场（作为非定常绕流计算的初场）时，本文采用松驰迭代法直接求解跨音速定常非线性积分方程，而不是采用时间相关法求解非定常非线性积分方程，这样大大节省了计算机时；（2）将以体积分形式出现的影响系数化为面积分，并获得解析公式，这样便于分析和编写程序；（3）对运动的激波，本文通过在每一个时间步长上采用激波捕捉法而得到，而不是在积分方程中附加激波运动项，因而处理起来简单方便得多。
