Based on Wu's elimination method and "divide-and-conquer" strategy, the undetermined coefficient method for constructing polynomial conservation laws of nonlinear differential-difference equations was improved. Furthermore, a Maple package CLawDDEs was developed to automatically derive conserved densities and associated fluxes of polynomial differential-difference equations.

基于吴消元法和"分治"策略，改进了基于标度不变性构造非线性微分差分方程多项式形式守恒律的待定系数算法，并在计算机代数系统Maple上实现了改进后的算法，其中的软件包CLawDDEs可自动推导出微分差分方程的守恒密度及连带流。

We proposed a example selection method based on the consistence, using two classifiers : Transductive HMM and fnTBL to combine a classification system to perform the Chinese text chunking task with the small-scale labled Chinese treebank and large-scale unlabled Chinese corpus. The ...

文中提出了基于一致性的co training选取方法将增益的隐马尔可夫模型和基于转换规则的分类器组合成一个分类体系，并与自我训练方法进行了比较，在小规模汉语树库语料和大规模未带标汉语语料上进行中文组块识别，实验结果要比单纯使用小规模的树库语料有所提高，F值分别达到了85 34%和83 4 1%，分别提高了2 13%和7 2 1%。

I am no more lonely than the Millbrook, or a weathercock, or the north star, or the south wind, or an April shower, or a January thaw, or the first spider in a new house

比起牧场上的一朵毛蕊花，一支蒲公英，一片豆叶，一束酢浆草，一只牛虻或大黄蜂来，我并不孤单多少；比想密尔溪，风标，北极星，南风，四月春雨，正月融雪，或者新房中的第一只蜘蛛，我也并不更加孤单。

If Whittier and Intel have their way, they will be inside, well, everything.

如果怀特和英特尔继续在他们的道路上驰骋，他们将会将英特尔植入所有的东西，他们的一个品牌将会覆盖所有的东西，不论是智能手机、还是车载电脑、以及各种价位的家用电脑，还有大众办公系统，像是兔子一样，人们将会看到奔腾芯片的大爆发，这些芯片将遍及每一件产品，从低价位到高价位产品，远远超过了英特尔标志在1991年首次推出内置英特尔标志时候所想象的那样。

YAG/CO2 laser marking machine can be fine in metal, leather, wood, two-color panels, plexiglass, crystal, such as different materials on a variety of text and logo engraving, sculpture has a certain depth is not easy indelible and very beautiful, with wire Network printing can not mark the effect.

YAG/CO2激光打标机能够精细地在金属、皮革、木材、双色板、有机玻璃、水晶等不同材料上雕刻各种文字和图案，雕刻具有一定的深度不易磨灭，而且非常美观，具备丝网印刷达不到的标记效果。

The axes have been drawn on for clarity, but the pivot point of the object is its actual center in X and Z, with the Y set to the base of the object.

轴已经被清楚的标上了，但是物体的轴心是其在基于物体设置的X、Y、Z轴的实际中心。

After transformation, larger coefficients lie on those pixels with smaller distance according to the zero vector.

变换后，较大的变换系数集中在四维子矩阵中下标矢量与零矢量距离较小的元素上。

Using the concept of soil-moisture-balance suggested in Palmer-drought-model for reference, daily available water content in upper and lower levels of soil is simulated with daily maximum temperature and rainfall data. Drought dynamic index, I, defined by AWC of lower level soil, with definite physical meaning and data acquirability, is presented in the paper, by which a drought course can be depict in detail, and how a drought course occurs and develops can be monitored and evaluated dynamically.

借鉴帕默尔早度模式中的土壤水份平衡概念，采用逐日气温和降水量资料，对土壤有效含水量（分上、下2层）进行了逐日滚动模拟，提出了以下层土壤有效含水量构建逐日干旱动态强度指数I(下标 D，该指数物理意义明确，实时资料可得，能够刻画干旱过程的丰富细节，实现对干旱发生、发展及其强度的逐日动态监测与评估。
