本发明涉及一种用于测定植物冠层群体光合作用的冠层叶室，由正方形的光合室和圆柱状的土壤固定体两部分结合而成，冠层叶室下部土壤固定体设有把手，基部为波纹状切口，可以很容易地把固定体插入土壤中形成密闭的冠层叶室，固定体上口与光合室底壁的圆形开口吻合，使冠层叶室的内腔形成一个整体；光合室顶壁用双面胶和光合薄膜密封，以保证光合室稳定的透光性能；光合室侧壁内安装一个小型风扇，由装在侧壁外的电池和开关控制，风扇可使冠层叶室内的气体迅速达到平衡。

Models for the electromagnetic interaction between the target and trunks or between the trunks and trunks are developed, and these models are used to derive the coherent fields scattered by the target and fractal forest. Then, the polarization angular correlation function is calculated by using azimuthal angular averaging, and used to detection target buried in forest.

本文用L系统对森林环境进行了理论建模；研究了有限长分层介质圆柱的树干散射模型；分析了倾斜粗糙地面上树干及分形树的电磁散射特性；讨论了环境对确定目标电磁散射特性的影响；研究了环境与隐蔽目标复合电磁散射，用角相关函数、极化角相关函数对隐蔽目标进行了检测。

In this version, the spike columns were given heavily textured surfaces, employing a style reminiscent of Antonio Gaudi, architect of Barcelona's Cathedral of the Holy Family in Spain.

在这个设计里，尖顶圆柱被赋予一种沉重粗糙的表面，使用了一种安东尼奥·古地——西班牙巴塞罗纳圣家族大教堂的建筑师——的怀旧式样。

The Essen is graceful, in is "Miss in the US" a book composes "the miss and forming not on the scene" in a article pointed out that tan oak Bussy Ye habitually uses the column suggested periphery the space does not have the direction unrestricted flow extension,, but the miss stainless steel cruciform column lies in implicitly the arrow quantification all around "spatial".

一文中指出，柯布西耶惯用的圆柱暗示了周围空间无方向地自由流动伸展，而密斯的不锈钢十字形柱则在于含蓄地矢量化四周的"空"。埃森曼的观点从结构上可以讲的通，然而我认为

The broidered and dentated cordon of the eight and twenty royal niches; the immense central rose window, flanked by its two lateral windows, like a priest by his deacon and subdeacon; the frail and lofty gallery of trefoil arcades, which supports a heavy platform above its fine, slender columns; and lastly, the two black and massive towers with their slate penthouses, harmonious parts of a magnificent whole, superposed in five gigantic stories;--develop themselves before the eye, in a mass and without confusion,with their innumerable details of statuary, carving, and sculpture, joined powerfully to the tranquil grandeur of the whole

那镂刻着二十八座列王雕像神龛的锯齿状束带层，那正中巨大的花瓣格子窗户，两侧有两扇犹如助祭和副助祭站在祭师两旁的侧窗，那用秀丽小圆柱支撑着厚重平台的又高又削的梅花拱廊，还有两座巍巍、黝黝的钟楼，石板的前檐，上下共六大层，都是那雄伟壮丽整体中的和谐部分，所有这一切，连同强有力依附于这肃穆庄严整体的那无数浮雕、雕塑、镂錾细部，都相继而又同时地，成群而又有条不紊地展现在眼前。注意，注意力集中

The deformation and damage principles of long cylinder colliding with ground were studied in this paper.

对圆柱碰撞地面的变形及破坏规律进行了探讨，在此基础上，建立了构筑物倒塌冲击地面的计算模型，并研究了构筑物不同的着地冲击方式对构筑物破坏和地面受力的影响。

It includes back, left spring, left sliding block, right sliding block, right spring and cylinder. They are formed stiffness changing mechanism in back. The left spring is set between the left vertical surface of the left sliding block and the left inner wall of the back. The right spring is right the opposite.
