This thesis proposes a lossless digital watermarking algorithm based on Harr wavelet transform, which can recover the original image without any distortion from the marked image after the watermark has been extracted.

提出了基于Harr小波的彩色图像可逆水印算法，采取闭环控制自适应地修改其高频子带系数以嵌入水印。

In the qualitative and quantitative analyses, four kinds of methods such as cause analysis, vector statistics, fuzzy analysis and systematic cluster were synthesized and the applicability of them analyzed. Finally, in combination with the hydrometeorological characteristic of the north slope climatic zone of Tian Mountain and the operation of the reservoir, the flood season range are divided: 10 July 30 July flood season as main flood season and 1 August 15 August as later flood season. The result?

针对高山冰川作用下流域水库汛期分期的实际问题，以玛纳斯河流域夹河子水库为研究对象，识别汛期划分的主要影响因素，选择汛期划分依据，采用定性和定量分析相结合的方式，综合成因数理统计、矢量统计、模糊分析、系统聚类4种汛期分期方法，分析各种方法适用性，提取合理成分，结合天山北坡气候带的水文气象特征和水库控制运用特点，确定汛期范围：7月10日至7月30日为前汛期， 8月1日至8月15日为后汛期。

PCSS-driven Pockels cells: the PCSS delivers a sub-nanosecond pulse to an electro-optical crystal which controls the lasing efficiency in laser cavities ranging from microchip microjoule lasers to table-top multiJoule lasers.

So the controllability and observability of the saturated nonlinear system is studied at first.

本文主要采用基于算子理论的系统输入/输出方法研究了一类控制输入饱和非线性系统。

The international nutrient value assessment method was applied to the overall assessment of the protein nutrient value of Pholiota adiposa mycelia. The assessing result showed that the total essential amino acid in Pholiota adiposa mycelia was very high, making up to about 40.0% of the total amino acids.

相对黄伞子实体的栽培而言，通过液体发酵技术生产黄伞菌丝体具有产量高、周期短、不受气候变化的影响、条件易于控制等优点，因此，对黄伞菌丝的液体发酵工艺和菌丝体的营养价值进行研究具有重要的实际意义。

The pathogen was i dentified as Botryosphaeria ribis,which belongs to Ascomycotina.The asexual pathogen was Phoma moricola Sacc,which belongs to Deuteromycotina. The stitable conditions for germ feat growth w ere temperature: 30, pH:7.0, relative humidity 98% in 3% maltose. Carbendazim and asomate could control thi s disease effectively.

研究表明：（1）该病是由子囊菌亚门茶子葡萄座腔菌所致，无性为半知菌亚门桑茎点菌；（2）该菌适宜生长的温度为30℃，pH为7.0 ；3%麦芽糖和 98%相对湿度对无性孢子萌发极为有利；（3）多菌灵和福美砷能有效控制该病。

ConclusionThe method is fast,simple,accurate and reproducible and can be used for the quality control of Phyllanthus emblica L.

结论该方法操作简便、快速，有良好的精密度和准确性，可用于余甘子药材的质量控制。

Previous studies indicate two possibilities of the formation of the greigite: 1 the seepage of seawater during the postglacial transgression provides sulfate and makes the reducing diagenetic conditions; 2 it may be precipitated as the authengenic mineral in marine or lacustrine sediments during the low sea-level stand of the Late Pleistocene.

本研究在前期工作基础上，针对已发现的硫复铁矿富集区选择典型柱状样6根(深约1.5-2.5m，长柱样；B436、B437、B439、B459、B483、B484)，同时于扬子浅滩前缘新获取柱状样4根(深约0.3-0.5m，短柱样；ST9、ST13、ST15、ST23)，进行了U系测年，粒度分析、磁性测量、X—射线衍射分析、微体古生物鉴定分析、粘土矿物和化学元素含量测试，试图揭示东海外陆架浅部地层结构、揭露硫复铁矿在地层中的分布规律及成因机制，从而探讨该区晚更新世以来海平面波动模式及其控制下的地层发育。

CEA promotor could control the expression of EC-CD gene in CEA positive colorectal carcinoma cells specifically in vitro.

CEA启动子能够控制EC-CD基因专一性地在CEA阳性的结肠癌细胞中表达，从而实现EC-CD基因的靶向性作用。

Yes most of the sinkable programs are built upon large scale sub-classing of the standard windows controls.

是的sinkable大部分节目是建立在大规模的子窗口分级控制标准。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
