By using the transfer matrix method of multibody system, the hard problem of computation of the vibration characteristics of LRMLRS coupled with rigid bodies and elastic bodies is solved which is very difficult to the ordinary dynamic methods, and the vibration characteristics of LRMLRS which is varied when the number of rockets in the launch device is varied, is obtained conveniently. By developing augmented eigenvectors of the LRMLRS and its orthogonality conditions, the nonorthogonality problem of the multibody system including rigid bodies and elastic bodies is solved and the exact analysis of the dynamics response of the LRMLRS including rigid bodies and elastic bodies is realized. By using the random integer programming method, the hard optimization problem which contains continuous variables, discrete variables and random variables at the same time is solved. This method provides a technology for optimum design with random variables and discrete variables. The dynamic optimum design is realized to decrease the number of rockets consumption in the LRMLRS test. The simulation system of dispersion of fire is established by using the maximum entropy method to estimate dispersion of fire.

Seepage velocity smoothly change from a steady value to a new steady value, the ratio of the new steady value over the original steady value might increase hundreds of thousand times or even more, but it is always finite.（3）Water-inrush goes with the failure of rock strata, but seepage velocity can not increase unendingly, so seepage flow cant be unstable.

研究表明：由于非Darcy流β因子恒为正值，渗流系统总是稳定的；当渗透特性随时间变化时，渗流速度从一稳定值平滑地过渡到一新的稳定值，新的稳定值与原稳定值之比可以增大到几万至几百万倍，但是总是有限的；突水是岩层结构破裂引起的渗流速度快速或急剧变化，但渗流速度不可能无止境地增大，即渗流不可能失稳。

After 20 days, the contents of linoleic acid and linolenic acid begin to increase. However, the percentage of stearic acid decreases and the content of oleic acid has no change. So it can be concluded that in immobilized state the fatty acid compositions of plasma membrane have a tendency to shift towards unsaturation and the index of unsaturated fatty acid increases.

同时膜脂肪酸代谢也发生了显著的变化，从第20天后，膜亚油酸和亚麻酸的含量开始增多，而硬脂酸的含量开始下降，油酸的含量没有变化，膜脂肪酸组分趋向不饱和化，脂肪酸的不饱和指数增高。

The simulation results show that there are many factors to influence the reverberation, each of them has different contribution to the reverberation, and the angles configurations and the characters of interface have main function, and the effect of the change of sound velocity on reverberation can be ignored.

模型仿真结果表明，影响双基地声纳混响的因素众多，每个因素在对双基地混响的贡献是不一样的，双基地角度的配置和界面性质变化对混响的影响很大，而声速的变化对混响的影响可以忽略不计。

The results showed that temperature and CO2 concentration coupling had great effects on the photosynthesis biomass production of Vitex negundo and Setaria viridis; light intensity and CO2 concentration were the key factors for P and T of Agrimonia pilosa and Commelina communis; the temperature change had little effect on A-Ci curve of Agrimonia pilosa and the photosynthesis of Vitex negundo was not sensitive to temperature change.

By using spectrophotometry method determinated the anthocyanindin and chlorophyll content in different parts of Prunus wilsonii leaves,results showed that,as time changes,anthocyanins content in different parts of the leaves showed a low-high-low change in trend,the analysis of variance,the difference is not significant,relations between anthocyanidin content in Prunus wilsonii leaves and the position of health was not obvious,anthocyanindin content in the same part are far greater than chlorophyll content,...

用分光光度法对紫叶稠李叶片不同部位的花青素和叶绿素进行了测定，结果表明，随着时间的变化，不同部位叶片的花青素均呈现低-高-低的变化趋势，经方差分析，差异性不显著，说明紫叶稠李叶片花青素含量跟着生的部位关系不明显；同一部位的花青素含量远远大于叶绿素含量，这也是紫叶稠李叶片在整个生长季呈现紫红色的原因。

With the observation of the outward appearances, it can be known roughly that if the sample was added with adulterations. Since the beeswax dissolves in the benzene but the adulterations, such as gypsum, starch and so on do not, these can be determined. By the verification of acid value and alcohol dissolve ability, the acid or non acid added can be determined. By the change of saponification value, the ester or non ester added can be determined. By the carbonification degree in the concentrated sulphuric acid, the mineral wax, such as paraffin wax added can be determined.

通过样品外观的观察初步定性是否掺有杂质；利用纯蜂蜡在苯中溶解，而掺入的石膏、面粉和淀粉等杂质在苯中不溶而定量鉴定这类杂质；由酸值变化和乙醇溶解物的量，测定掺入的硬脂酸等酸性物质或其它的非酸性物质；由皂化值变化，定量测定掺入的动物脂等酯类物质或其它的非酯类物质；根据蜂蜡中的烃类在浓硫酸中可被炭化，加入的石蜡等矿物蜡不被炭化来测定此类掺杂物。

The most heavy flow ability of barrage swirl is controlled by fastenning device and barrage size, the most heavy discharge is more when barrage aperture is bigger, the influence of barrage position on discharge is not obvious; The pressure of the end of the shaft and fastenning device increases which aroused by barrage, and there is a restraining action to flow waving of the shaft; The barrage aperture is smaller, the increase of pressure is heavier, the influence of position to the increase of pressure is not obvious; The positive pressure of the level section in the hole between fastenning device and barrage increases obviously, the change of press along length reduces, mural press in the hydrosphere separating area of outlet of fastenning device becomes positive pressure, which is propitious to the increase of flow cavitate number in the low pressure area of the outlet of fastenning device; The influence of change of swirl cavum diameter caused by barrage to ventilating state is obvious.

阻塞旋流最大泄流能力由起旋器及阻塞体型共同控制，降低了泄洪洞的泄流量，孔径大的阻塞最大下泄流量较大，阻塞位置对泄流量的影响不明显；阻塞引起竖井及起旋器端头压力增大，对竖井部分的水流波动具有抑制作用；阻塞孔径越小，压力增加越大，位置对压力增大影响不明显；起旋器与阻塞之间水平洞段的止压力明显增加，沿程压力变化减小，起旋器出口的水气分离区壁面压力变为正压力，有利于起旋器出口低压区水流空化数的提高；阻塞引起的旋流空腔直径变化对通气状态产生明显影响。
