Creation of multimedia teaching softwares: guiding by the teaching syllabus of dendrology and the demands of contents, Chinese-English bilingual multimedia teaching softwares are created to make salient features of trees combine with relative images. That helps students easily and intuitively to master plant characters and their English terms at the same time.

制作多媒体教学软件：根据教学大纲和教学内容，利用收集的图片、图像资料制作同时具有中文和英文的双语多媒体课件，教材中的树木文字描述特征与相应的图片紧密结合，使抽象的概念与直观的图片形象，让学生在掌握植物中文的特征同时也掌握相应的专业外语。

In the paper four aspects have been studied:(1) tree and distributing, belonging to the correlative contents of the dendrology,(2) the macroscopical character in virtue of magnifier and entitative microscope observing the three sections (cross section, radial section and tangential section );(3) the microcosmic character, in virtue of light microscope observing slices.

本文从以下四个方面进行了研究：(1)树木及分布，树木学方面相关的内容；(2)木材宏观特征，借助扩大镜和实体显微镜，在木材的三个标准切面，即横切面、径切面和弦切面上进行观察；(3)木材微观特征，借助光学显微镜观察切片。

In the western region of Sanhe-Pinggu earthquake area, the stacked deep seismic reflection section shows 2～3 groups of strong reflective layers and a series of basement faults. In the eastern region of Sanhe-Pinggu earthquake area, there is a set of dense, westward-dipping, reflective strata with relatively strong energy, which have the typical characteristics of sedimentary basin. The largest depth of the sedimentary basin is about 8～9 km.

剖面TWT3～4 s以上，反射层位丰富，构造形态清晰，且在剖面上具有明显不同的构造特征；在三河—平谷地震区以西，剖面揭示了2～3组反射能量较强的反射震相和一系列错断基底面的断裂，在三河—平谷地震区以东，为一套自东向西倾伏的密集强反射层，这套反射具有典型的沉积盆地特征，盆地最深处约为8～9 km。

As a consequence, based on the water system denseness method and the tectonic d...

论文在分析地应力及地应力场特征和规律基础上，论述了地应力场主要组成部分；较系统地阐述了粗集理论的主要内容，应用粗集理论计算各因素对地应力场的影响，并提出基于粗集理论计算权重的方法；解释了图像滤波使图像边界模糊的原因，提出基于粗集理论的图像滤波方法；研究TM图像各波段的信息特征、最佳波段组合及各波段赋色；剖析构造形迹在反推构造应力场中作用，建立断裂构造形成时的构造力学模型；利用遥感资料解译了与新构造应力场密切相关的水系，在GIS支持下，应用水系密集度方法和构造力学模型计算了新构造应力场的方向与大小；分析了地形起伏对重力场的影响，并建立了相应的数学模型；研究了地应力在矿山巷道及开采设计中的应用。

Other diagnostic features include the presence of a crest along the anterodorsal midlines of the premaxillae,the edentulous maxilla,the presence of a groove-like trough along with the anterolateral margin of the maxilla on the ventral surface,the presence of six conical premaxillary teeth,and no more than six conical dentary teeth which are restricted to the anterior portion of the dentary.

其他主要特征有：前颌骨沿前背中央有一隆嵴；上颌仅前颌骨有6枚圆锥形齿，无上颌骨齿；上颌骨沿前腹侧缘有一沟槽；下颌齿骨齿都集中在前端且至多不超过6枚。依据上述这些特征很易把短吻贫齿龙与其他已知海龙相区别。短吻贫齿龙头骨顶面松果孔大且很前位，头骨腭面的锄骨和翼骨均无齿，它的颈较长(至少可以辨认出13个颈椎)。

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.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

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.
