The nonlinear hyperbolic conservation laws of the transient flow of the media in gas pipeline are hard to he solved, so, the control conservation laws are constituted of mass, momentum arid energy conservation laws, TVD/Godunov hydrid algorithm is used to simulate the transient flow in gas pipeline, and the traditional splitting approach processing nonlinear convection in momentum equation is dismissed ,the convection tern; is directly processed, in the way, the stablization of the algorithm and emulating accuracy of the transient flow are greatly improved.

针对管道中介质瞬变流动的非线性偏微分方程组难以解析求解的问题，由质量、动量、能量三个偏微分方程构成的控制方程组，应用TVD/Godunov混合算法数值模拟天然气管道中气体的瞬变流动，摒弃了传统的差分方法时动量方程非线性时流项的线性化处理，而直接处理非线性对流项，从而大大提高了算法的稳定性和管道瞬变流动的仿真精度。

Using hydrodynamical/N-body simulations and pure dark matter simulations, we found the dark haloes in the first kind of simualtions are more concentrated than in the second kind of simualtions. This result could increase the predicted probability of giant-arcs in gavitational lensing and cancel the great difference between the theoretical and observational results.

用含气体的数值模拟与纯暗物质的数值模拟比较，发现前者暗晕中的暗物质分布比后者中的更加密集，密集参数更大，这可能可以提高理论预言的引力巨弧的概率从而弥补理论与观测结果间的差距。

Directing at the data distortion caused by the fault of sensors, and considering the factors influencing the measurement of certain exhaust gas in an animal barn such as temporal, spatial and environmental parameters, neural network is introduced to data fusion so as to figure out the missed data due to the faults of this sensor measuring the value of this exhaust gas. By this method, total emission of nocuous gases from the barn is measured accurately, and the emission of exhaust gases beyond normal standard was controlled.

针对因传感器故障而失真的数据，综合考虑对畜禽场排放的某一废气测量值的时间、空间和环境等多种影响因素，使用基于神经网络的数据融合方法来估算该废气的浓度，实现失真数据的恢复，从而精确地测量出养殖场连续排放的有害气体的总量，对超标排放进行监控。

The experimental results denoted that the finer pearlite along the austenite boundaries in the as-cast Cr30Ni20NRE steel disappeared first under long-term and high-temperature service condition, and that an umber of Cr- richened carbides were formed due to unila-teral carburizing at long-term and high- temperature, consequently causing Ni to concentrate, bulging and calalyzing decomposition of the carburizing gas.

试验结果表明，长期在高温条件下服役，铸态Cr30Ni20NRE耐热钢中沿奥氏体晶界的珠光首先融入奥氏体，长期高温单边渗碳形成大量富铬碳化物，促使镍富集并起泡形成瘤状物，催化含碳气体的分解；表层瘤状物使辐射管表层疏松，表面积扩张，加快了碳向基体的渗入，提供了碳化物持续长大的条件，并引起沿碳化物周边开裂和奥氏体基体严重萎缩；合金元素的重新分布造成主合金元素铬和镍产生两极分化，镍和硅的富集促使石墨化，与侵入的氧形成内部氧化空洞和膨胀疏松，最终导致构件穿孔失效。

The results show that:(1) lower concentration or lower initial pH of citrate solution results in a better desorption efficiency;(2) sparging inert gas or adding surfactants into the liquid can lower the viscosity of the solution and the cavitating threshold, and raise the desorption efficiency of SO2;(3) by comparing the experimental results and theoretical analyses , it was concluded that the experimental results are in accordance with the theoretical analyses.

结果表明：(1)在柠檬酸钠浓度较低，或者柠檬酸钠溶液初始pH值较低的条件下均能产生较好的解吸效果；(2)少量惰性气体的通入或者表面活性剂的加入能够降低溶液黏度，产生空化效应，从而提高了SO2的解吸率；(3)通过对比实验证明解吸结果与理论分析相吻合，其研究结果为SO2的深度解吸提供了技术思路，也为该项技术的工业放大提供了一定的基础数据。

In addition, research reveals that in many cases, eating "free-range" and "organic" meat, dairy, and eggs does not substantially reduce greenhouse gas emissions, because free-range cattle, for example, are not fattened as quickly as feedlot cattle, so the reductions in carbon dioxide equivalents in foregoing chemical fertilizers and pesticides are nearly offset by these factors.

此外，研究也揭示：在许多案例中，吃&自由放养&的和&有机&的肉、乳制品和蛋实际上并未减少温室气体的排放。例如，自由放养的牛长胖的速度不如养殖场的牛，所减少的二氧化碳排放量大体跟前面提到的化肥和农药等因素造成的碳排量等值，正好两相抵消。

The application of the alloy that can effectively reduce the release of hydrogen, the special technique in manufacturing grid, and the appropriate match of active materials of both negative plates and positive plates, all these enable spiral valve-regulated sealed lead-acid battery, greatly restrain the release of hydrogen from negative plates, at the same time the generated oxygen, due to overcharge of positive plates, arrive at negative plates through the diaphragm and compose with lead in the negative, thus enable the recombination of gas inside of the battery and prevent the case of water loss so that water addition is free.

选择特点：有较高的放电电压曲线，使用环境宽松，能完全释放能量，适用于1min以内的支撑时间，与GCplus15配合使用，可保障变频器恒定的直流电压。卷绕式阀控密封铅酸蓄电池通过采用具有极高析氢过电位的合金通过特殊工艺制造板栅，同时对正负极活性物质量的合理匹配等工艺措施，使得负极上发生的析氢过程得以最大限度地受到抑制，同时正极因过充电所产生的氧气通过隔膜到达负极，并与负极上的铅发生反应，生成水，这样便使得电池内部气体的再复合，防止失水，实现免维护。

As discussed here, it is differences in pressure that are dangerous to organisms, so they will experience no significant problems as long as the liquid in their body is at equally high pressure as the surrounding water, and as long as they have no gas-filled body cavities at lower pressure like humans do.

就这里讨论的而言，是压力的差异在威胁这些生物，所以只要它们体内的液体和周围水域处在同样的高压，只要它们没有如同人类的充满气体的低压体腔，那么它们就不会遇到太大的麻烦。

It is indicated that hydrides are easily decomposed. On the other hand, oxides could not be decomposed without the presence of carbon.

其次对熔体中各种气体的熔解度及蒸气压进行分析，特别是各种金属元素的影响，指出某些合金元素影响很大。C的存在和CO的析出保证了氧的定量析出，对氮的析出也有良好的影响。
