他很惊奇地发现自己需要做的工作其实很少。

In chapter 1, an up to now synthetically evaluation is given on the research ways and conclusions about jet in cross-flow. Considering the shortage of previous research ways and techniques (the instantaneous flow field and vortices field can not be properly get), in addition to the deficiency of corresponding conclusion (mainly concentrate on the analysis of time-average but little on structures of flow and action of vortex), the research way and content is draft out in this part. Though PIV, the time-average, instantaneous flow field and vortices field can be get, that will unveil the coherent vortex and its course of generation, development and evolvement, with the assistance of K-ε model and Hybrid Finite Analytic Method , which will proof-test the experiment result and bring some complementary, more profound research about the 3-D characters can be done. Using some fundamental topological theory and principle on flow analysis, with anglicizing of vortex structure, a reasonable description is the topological characteristic of near field in JICF given.

首先在第一章中对横流中湍射流的以往研究方法和研究成果给予了综合的评述,针对横流中湍射流旋涡结构以往研究中研究方法的局限性(不能很好得到流动的瞬态流场及涡量场)和相应研究成果中存在的不足(大都集中在时均特性的分析,对流动的内部结构和旋涡的运动阐述很少),明确了本文的研究方法和研究内容:通过PIV流动测量显示技术得到流动的时均及瞬态流场、涡量场,来揭示横流中湍射流的时均、瞬态流场、涡量分布特性,和各种具有拟序结构性质的复杂涡系的产生、发展及演化过程;结合湍流k-ε双方程模型及相应的HFAM计算方法,对于实验进行相互验证和补充,从而更为充分地研究各种旋涡的三维特性;利用拓扑分析的一些基本原理及相关规则,依据对各种旋涡结构的分析,做出对射流近区流场拓扑性质的合理描述。

She sat unmoving for a long time. Her eyes blinked rarely.

All these characteristics can extend frequency band , reduce antennaelectric size and improve impedance characteristics. In order to miniaturization ofantenna, impedance complete compensate and matching optimization of electricallysmall antenna are brought forward, and this method is applied to the discage antennas.

从阻抗特性和辐射特性的实测数据表明,水加载单极振子天线的谐振频率能很好地向低端下移,局部水加载单极圆锥天线在保持原有宽频带特性的前提下,以较少的效率损失实现了较大范围向低频区扩展,即天线小型化,这将为短波超短波波段天线进一步的小型化设计提供很好的思路。

By the late 1950s fewer new artists were becoming well-known for making expressive, gestural art.

品味的变化很难准确地说,抽象表现艺术是什么时候开始走下坡路的,在19世纪50年代末,很少会有因为做出抽象表现艺术形式而出名的新的艺术家出现。

Spikelets with 1 floret; rachilla disarticulating above glumes, extension beyond floret absent or small and glabrous, rarely better developed and penicillate; glumes persistent, subequal or unequal with lower longer, narrowly lanceolate, much exceeding floret, lower glume 1-veined, upper glume 3-veined at base, apex finely acuminate or subulate; floret callus conspicuously bearded, hairs much exceeding floret; lemma ca. 1/2 as long as glumes, hyaline, 3–5-veined, awned, apex erose, denticulate or deeply 2-lobed; awn very slender, straight or almost so, arising from lemma back, apex or between teeth; palea 1/2 as long to slightly shorter than lemma.

小穗具1小花;在缺席或者小和无毛小花以外高于颖片脱节的小穗轴,扩展,很少很好地发展,具毛撮;颖片宿存,近等长或不等长用低长时间,狭披针形,很多超过小花,小花结茧显著公然反对,头发很多超过小花;外稃大约1/2的倍于颖片,透明,3-5-脉,具芒,啮蚀状的顶,或者深深2裂的具小齿;返回的芒非常细长,直的或几乎如此,生于外稃,或者在牙齿之间的顶;作为稍短于外稃的长时期的内稃1/2。

But, somehow, the cotton always failed, and the garden ,due to Mrs. Slattery's constant childbearing, seldom furnished enough to feed her flock.

但是,不知怎么回事,棉花总是长得很差,而园子,由于斯兰特瑞太太接二连三地生孩子而很少长出足够全家吃的菜。

Yes , As I look back the world I left behind, it all so clear to me, the beauty that wait to be unwilled , the mystery that long uncovered , but people so rarely stop to take a look, they just keep moving, it's the shame really , there are so much to seeing .

是的,当我回头看身后的这个世界时,我看得如此的清晰,有那么多有待发现的美丽,和那么多有待揭幕的秘密。但人们很少会停下来看上一眼,他们只是不停地往前走。这真的很遗憾,有那么多值得一看的东西。

Yes , As I look back the world I left behind, it all so clear to me, the beauty that wait to be unwilled , the mystery that long uncovered , but people so rarely stop to take a look, they just keep moving, it's the shame really , there are so much to seeing .

是的, 当我回头看看身后这个世界时,一切都如此的清晰。等待被发现的美丽。和等待被揭开的神秘。但人们很少会停下来看上一眼。他们只是不停地往前走。这真的很遗憾,有那么多值得一看的东西。

The result pointed out that the vertical distribution of foliage for each species was different,however,generally speaking,the foliage in upper crown (0.3CL) for broad-leaved species in natural secondary forest took a small percentage,about 10%;in middle or middle lower of the crown(0.4CL to 0.8CL) the branches here took the majority percentage of whole foliage,almost 60%to 75%;but in lower crown(0.8CL),there was about 10%of whole foliage.(5)The interspecies competition of trees in secondary forest was expressed by Hegyi competitioin index,and the active competitor was calculated by the competition zone radius and the tree position,DBH,and distance in the zone,it was not all competitors in tranditional calculation.The study introduced crown area overlap index to describe the crown competition between subject tree and its competitors,furthermore,the crown area was classified into 5 levels with a method of equal crown projection area,therefor,the resulting crown area overlap index showed more realities of existing stand conditons.(6)Based on the theoretics of multiply divide,the spatial strcture optimizing model of secondary forest stand selective thinning was developed by diversity mingling,aggregation index,competition index and crown area overlap index,also designed 10 constraint conditions which were related to forestry meanings,the objective function was solved by the implicit enumeration method with LINGO 9.0,using 0-1 integer programming.

并且得出,每个树种在树冠内相对高度上的叶量的垂直分布是不同的,天然次生林阔叶树种的叶量在树冠的上部(0.3CL以下)所占比例很小,约占10%左右;在树冠的中部以及中下部(0.4CL~0.8CL),叶量所占比例最大,几乎集中了整个树冠60%~75%的叶量;而在树冠的下部(0.8CL以下),几乎占很少的叶量,大约10%左右。5、采用Hegyi竞争指数来表现次生林内林木的竞争关系,并且根据竞争圈的大小和林木在竞争圈内的分布位置、大小与距离来计算有效的竞争木,并不是传统意义上的全部竞争木;本研究提出用树冠叠加指数来表示林木与周围树木的树冠竞争情况,并采用等树冠投影面积法把树冠分为5级,这样计算的树冠叠加指数更加与现实林分相符。6、本研究基于乘除法的思想,用多样性混交度、聚集指数、竞争指数和树冠叠加指数构建了天然次生林择伐空间优化模型,设计了10个与林学意义相一致的约束条件,并采用0-1整数规划的思路,在LINGO9.0软件中使用了隐枚举法对目标函数求得最优解。7、以M702标准地为应用实例,具体计算出了每株采伐木,经过择伐后,目标函数值按模型设计的要求发生了极大的改变,增加了5倍多,说明了最后这个解的优良性,满足了设计的要求。
