It is found that there is a critical value (25mm) for the distance from the nozzle to the skin surface when the spray time is 40 ms. If the distance is too far or too near, heat extraction process will have different characteristics. The results could provide an applicable method for guiding the Cryogen Spray Cooling of laser therapy.

发现喷雾时间在40ms时，喷嘴到皮肤的距离具有一临界值（25mm），大于或小于此距离喷雾与皮肤的换热作用具有不同的特性，研究结果对于将制冷剂喷雾冷却实际应用于激光治疗鲜红斑痣手术具有重要的指导意义。

Bamboo mosaic virus encodes a 155-kDa replicase that the middle region contains a helicase-like domain according to the existence of several conserved featured motifs of helicase. Previous studies showed that the helicase-like domain exhibits both ATPase and RNA 5'-triphosphotase activities, and Mg2+ is essential for both activities. Mutagenesis of conserved motifs showed these amino acids play important roles for enzymatic activities. These results suggested that the properties of this denatured and renatured protein are coincident with other SF1 helicases.

从胺基酸序列分析显示，竹嵌纹病毒复制酵素中间区域的类解螺旋酵素具有解螺旋酵素的保留性胺基酸区域，经实验显示此蛋白具有ATPase和RNA 5'-triphosphatase活性，而且是依赖镁离子进行反应的，其中保留性胺基酸的突变会破坏其催化能力，说明这在大肠杆菌表达的蛋白质经过变性及重新摺叠的过程，具有和其他SF 1解螺旋酵素相似的特性。

Hageman, Ph.D., group director for discovery pharmaceutics for Bristol-Myers Squibb Company in Princeton, New Jersey."There's a growing push to quickly identify unacceptable biopharmaceutical properties and toxicologic effects, using the most advanced technologies available, thus eliminating compounds with poor properties early."

Hageman博士说："我们面临越来越大的压力去使用如今世界上最先进的技术尽快鉴定出不合适的生物药学特性以及毒性，从而尽早淘汰掉那些具有不良特性的先导化合物。"

产品的特性包括一根现金滑动条，用图片的方式显示可用现金，一个"省钱引擎"帮助客户建立开支规则，还包括一个相当具有可玩性的传输特性，被称之为"打猪"。

The method has some characteristics:(1) it adapts to medical images authentication due to the high Signal-to-Noise when the watermark was embedded into images.(2) It ensures the fragileness of watermark when it combines with the statistical information of wavelet coefficient to choose the embedding position.(3) It has a strong localization ability for tampering because of the characteristics of wavelet decomposition in the space-frequency domain.(4) It uses the secret key which can resist the malice attack even if opening the algorithm completely to protect the proposed method.

本算法具有以下几个特点：(1)图像嵌入水印后具有较高的信噪比，适用于医学图像的认证；(2)结合小波系数的统计信息来选择嵌入水印的位置，保证了水印的易碎性；(3)小波分解在空频域的特性使得算法对篡改具有很强的定位能力；(4)利用密钥对算法进行保护，即使公开算法，也能抵挡恶意攻击。

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.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
