However, the transformation rate from dominant stem to overtopped stem and from overtopped stem to dominant stem were the lowest. The interconversion of classified stem would increase as the stand density and the rate of L. gmelinii was going up. The altitude that classified stem mainly concentrated was less than 1000m, slope was less than 25°, aspect was south slope, position was at middle and lower, soil depth less than 17cm. The rate of no interconversion was 66.7% among overtopped stem. It should cut the overtopped stem as intermediate cutting.

优势木转被压木和被压木转优势木的转换率最低；随着林分密度和林分中落叶松比例增加，分级木相互转换数也增多；分级木转换现象主要集中在海拔＜1000m、坡度＜25°、坡向为阳坡、坡位为中下、土壤厚度＞17cm的林分中；被压木中，无转换的占66.7%，抚育采伐时应考虑伐除这些被压木。

For English, the strategy is achieved by using rules and exceptional dictionary. For Chinese, we discussed the strategies for processing the pronounciation of polyphone characters and the changing patterns of successive tones, which were realized by using the system dictionaries and the search function for semantic features in context.

In the thesis, based on the analysis of the grammar and structure of VRML 2.0, the conversion algorithm was designed again. The conversion tool was designed and developed, which also supports the position function by editing the position parameter.

本文在重点分析和研究VRML2.0结构与语法的基础上，通过重新设计转换算法，设计开发了新的工件3D模型文件转换工具，并加入了转换工具对定位参数输入功能的支持。

Sset future prices can be forecasted with filtering historical simulation by drawing from standardized residual density. The problem of inappropriate risk neutral assumption could be resolved by the calibration from density transformation. The transformation is to identify the state price density per unit probability through the parameter re-estimation by minimizing the mean squared error of market and model prices.

bstract：使用残差机率分配抽样的过滤历史模拟法可以作为未来资产价格的预测，而风险中立假设不适当的问题则可透过风险测度的转换予以解决，该转换过程系将市场价格与模型价格的均方差极小化求得估计校正后的新参数，作为状态价格机率分配的转换机制。

In conclusion, the algorithm has an important application in prophase of compiler development It can free programmer from repeated and tired manual transformation and avoid unnecessary energy waste.

本文提出的转换算法在编译器的开发前期有着比较重要的应用，应用算法进行非递归下降文法的自动转换，可以将开发人员从繁琐的手工转换中解脱出来，避免了不必要的精力浪费。

Infrared upconversion and optical storage thin film CaS∶Eu, Sm has been successfully developed by electron beam evaporation and radio frequency magnetron sputtering. Infrared upconversion efficiency of CaS∶Eu, Sm thin films with different thickness has been investigated by using the ultrashort infrared laser pulses with different FWHM.

采用电子束蒸发和磁控溅射技术制备了具有红外上转换和光存储特性的电子俘获材料CaS∶Eu，Sm薄膜，利用不同脉宽的超短红外激光测试了它们的红外上转换效率，指出CaS∶Eu，Sm薄膜的红外上转换发光效率不仅与制备工艺及热退火工艺密切相关，而且存在"耗尽"现象。

The paper prices bond and bond option, analyzing dynamic interest rate, regime-switching and option pricing. According to the affection of regime-switching to interest rate derivative pricing, the paper deduces the partial differential equation of bond pricing with Ito lemma, and obtains characteristic function and recursion equation of bond option.

从利率动态变化、结构转换和期权定价三个方面进行分析，对结构转换下的债券和债券期权进行定价，考虑了结构转换对利率衍生物定价的影响，利用Ito引理获得债券定价的偏微分方程，并得到债券期权定价的特征函数与递归等式。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

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.
