In this article, the domain structure of LBD genes, classes of LBD genes in model plants of monocotyledon or dicot, expression model, mutation phenotypes from loss of function or gain of function, and its relationship to other gene families were reviewed. Furthermore, the redundancy character of LBD genes, basic candidate function shared by LOB domain, and potential molecular mechanism of LBD genes interacting with other genes also were discussed.

本文对LBD基因的结构域特征、在单／双子叶模式植物中的分类、表达特点、己克隆LBD基因的功能及与其它基因或基因家族间的相互作用关系进行了综述，并对LBD基因在高等植物中的功能冗余特性、LOB结构域可能所具有的基本功能和LBD基因与其它基因相互作用的分子机制进行了探讨。

One is a bimodal volcanic assemblage, which formed during the rifting stage of the continental breakup theother is represented by flysch rocks, formed when the passive margin becomes stable. The composition of mafic rocks in the volcanic margin reflect their mantle origin and their crustal contamination. High temperature and low-pressure metamorphism can occur during the rifting stage and reflects a temporal trend of increasing temperature and decreasing pressure during the continental breakup.

被动陆缘的沉积建造由两套沉积物组成，一套是大陆解体的裂谷阶段所形成的陆相沉积物和双模式火山岩组合，另一套是稳定陆缘的复理石组合；岩装作用中基性岩类反应了物质直接源于上地慢的主要特点，并有部分受到地壳混染的特征；变质作用中高温低压环境主要发生在裂谷作用阶段，其特点反映了大陆解体过程中随着时间的增温和减压过程，而拆离伸展阶段则被脆性变形所代替。

Immunoblot results indicate the antibody can also cross react with the proteins of other silica-accumulated graminaceous plants, while it does not react with the proteins of dicotyledonous plants. These findings indicate that the homologous proteins of SBP117 are widely existed in the graminaceous plantss. This indicated silica accumulated in higher plants posses the character of systematic development.

免疫印迹检测表明此抗体还能与其它累积硅的禾本科植物硅体中的蛋白发生交叉反应，但不能与双子叶植物蛋白反应，这说明与SBP117相似的硅结合蛋白广泛存在于积累硅的禾本科植物之中，硅在高等植物中的积累具有系统发育上的特征。

Geological and geochemical features suggest that the bimodal volcanism took place in rift setting of continental margin, basic magma originated from not strongly depleted mantle, and rhyolite derived from the original melt formed by partial melting of granulite facies orthometamorphite in lower crust.

地质和地球化学特征指出吕梁群上部的双峰式火山岩形成于大陆边缘的裂谷环境，其中的玄武质岩浆起源于亏损程度较低的上地幔，并受到了陆壳物质的混染。酸性端元是由下地壳麻粒岩相正变质岩的部分熔融形成。

The grey scale of the pixels in image is expressed by quantum bit and the relation between two pixels is described by means of the superposition of two quantum bit in this paper.Based on this,the average of linear hermitian operator in this superposition can be used for judging the edge of image and a new method for edge detection of image is so created.The rationality of the method is interpreted by probability theory here.

利用量子比特表示图像像素的灰度，用双量子位叠加态来描述两像素之间的关联，通过线性厄米算符在该量子叠加态中的平均值来判断像素的边缘特征，由此建立了一种新的图像边缘检测方法，并从概率论的角度对该方法的合理性给予解释。

根据不同相态降水粒子的散射和空间取向等特征建立了基本形式为不对称的T型函数的模糊逻辑识别的隶属函数，完善了该识别方法的流程，并利用美国KOUN雷达的观测资料，详细讨论了利用双线偏振雷达观测资料识别降水粒子相态的方法，并对其在实际业务运用中的合理性和可行性进行分析探讨。

One important feature ofHamiltonian systems is that it has energy(its energic function is Hamiltonian func-tion),then,its solutions on 2-dimensional plane are some contour lines,the points onstable manifold emanating from hyperbolic equilibrium point have the same energyas that on unstable manifold,then,one can guess that they form a closed curve,i.e.homoclinic orbits under certain conditions,and the contour lines in the innerpart of homoclinic orbit are periodic orbits.

哈氏系统的一个重要特征是它有能量存在(以Hamiltonian函数作为它的能量)，那么在二维平面上，它的解表现为一些等值线，从双曲平衡点发出的稳定流形和不稳定流形上的点具有相同的能量，那么可以猜测，在一定条件下它们构成一条封闭的曲线，即同宿轨，而且其内部的等值线都是周期轨道。

To deblur edge after image magnifying,an adaptie edge sharpness presering image magnification is put forword,which can fit edges of any direction,gradient and amplitude,utilizing the gradient imgormation of the image and the properties of the hyperbolic tangent function haing reiewing the character of a typical edge.

针对图像放大后出现边缘模糊的现象，论文考察了典型边缘的特征，利用图像的梯度信息和双曲正切函数的性质，提出了一种较好地拟合任意方向、陡度和幅度的边缘，因此能够保持边缘锐度的自适应图像放大算法。

It is characterized by : the mechanical mouse moves and rolling around key operations into switching signals Circuit square with the square wave signal to substitute for the original mouse photosensitive sensors within the pulse signal, using the switch can be achieved mouse cursor movement and the mouse double-click a single operation, and the use of transmitting and receiving circuits instead of the mouse line, a remote-control mouse.

其特征是：将机械鼠标的滚动动作和左右键的作转换成开关信号，用方波电路产生的方波信号代替原鼠标内光敏传感器的脉冲信号，用相应的开关动作可以实现鼠标光标移动和鼠标的单双击作，而用发射和接收电路代替原来的鼠标线，可以实现鼠标的遥控。

The Lower/Upper Cretaceous boundary in Songliao Basin is,therefore,between the Quantou and Denglouku formations,instead of between the Quantou and Qingshankou formations.2.The dark mudstones and shales in the Member 1 of Qingshankou Formation are of high organic carbon and low diasteranes contents.Organic geochemical characters are illustrated by biomarkers of 28,30-bisnorhopane and gammacerane,and positive excursion of kerogen isotopes.It is suggested that the dark mudstones and shales in the Member 1 of Qingshankou Formation are the products of lake anoxic period.It corresponds to the oceanic anoxic event at Cenomanian-Turonian boundary in Cretaceous.3.Based on the study of biostratigraphy,chronostratigraphy,magnetostratigraphy and event stratigraphy,a correlation of the lacustrine sequence to marine standard has been proposed,i.e.,the Quantou Formation corresponds to Cenomanian stage,Qingshankou Formation correlates to Later Cenomanian-Early Turonian,Yaojia Formation to Later Turonian-Coniacian,Nenjiang Formation to Santonian-Campanian.Sifangtai and Minshui Formations to Maastrichtian. 4.Analysis of lithology,lithofacies and microfossils of Cretaceous in Songliao Basin, shows that shore and shallow lake facies yield the most abundant microfossil groups,and the predelta and deltaic distributary plain facies rich in fossils as well.In the shore and shallow lake areas during the high level periods(such as Qingshankou and Nenjiang sedimentary periods),the lacustrine biota are of high diversity and high abundance.

因此，松辽盆地上、下白垩统的界线应在泉头组的底界，即泉头组与登娄库组之间，而不是泉头组的顶界。2、青山口组一段黑色泥岩、页岩具有有机碳含量高、重排甾烷含量低，生物标志物出现28，30—双降藿烷和伽马蜡烷，干酷根碳同位素具有正向偏移等有机地球化学特征，表征为青山口组一段黑色页岩、油页岩是古湖泊缺氧事件的产物，它对应于白垩纪古海洋Cenomanian—Turonian期界线附近缺氧事件，二者具同步性。3、通过生物地层学、年代地层学、磁性地层学和事件地层学研究，认为泉头阶大体相当于Cenomanian阶，青山口阶相当于晚Cenomanian—早Turonian阶，姚家阶对应于晚Turonian—Coniacian阶，嫩江阶对应于Santonian—Campanian阶，四方台阶和明水阶相当于Maastrichtian阶。4、通过对松辽盆地上白垩统的岩性、岩相及微体化石分析，认为滨浅湖相是微体生物群最为发育的相带，其次为三角洲前缘相和三角洲分流平原相。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
