This product is brewed by a kind of international famous grape named Cabernet Sauvignon being in SHACHENG area cataclasm rock sandiness soil , fermented by oak wooden barrel with constant-temperature according strictly to criterion of V.D.Q.S, with advanced technology and special brew craft.

该产品是精选中国著名葡萄产区-沙城产区碎裂片岩沙质土壤栽培的国际酿酒葡萄名种梅鹿辄为原料，严格依照国际葡萄酒组织(V.D.Q.S优良产区酒)标准，采用法国专用酵母橡木桶发酵，经特殊酿造工艺精酿而成。

Because the temperature along the pipeline is not a constant, it changes the velocity of the negative-pressure-wave; the Romberg algorithm of numeric integral and the searching for algorithm are emloyed to locate the leakage.Multi-scale decomposition and reconstruction of wavelet transform is applied to filter the noise of negative-pressure-wave, which was brought by leakage. With the capacity to detect the signal singularity fast and accurately, wavelet transform was used to catch the break point of pressure signal. The work improved the accuracy of Δt in location formula, and the location accuracy is improved.

利用小波变换的多分辨分析和重构技术，对采集到的管道发生泄漏时产生的负压波信号进行了消噪处理；并利用小波变换技术对信号奇异点快速、准确的识别能力，对经过消噪处理后的负压波信号进行了奇异点捕捉，准确确定了定位公式中上、下游站点采集到的负压波奇异点的时间差△t，从而提高了定位的精度。

In this paper, we used molecule dynamics simulation technique in researching dielectric property. By analyzing the information that is provided from molecule dynamics simulation, we can got some dielectric properties like dielectric constant and chargeability. Firstly, 3D model of silicon dioxide was been built and geometric optimization was been used to make the model more correctly. Then the model was been put in calculation of molecule dynamics simulation with a definitive temperature.

本文针对氮化硼晶体在极端高温下的介电性能开展研究，首先建立六方氮化硼晶体的微观结构模型，通过几何优化对其进行进一步的结构修正，然后选择合适的力场、系综、积分时间步长和压力温度控制方法，对微观结构模型进行某一温度下的分子动力学计算，动力学计算达到平衡后得到该温度下电介质材料的微观结构模型和动力学特性。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
