In Chapter 4, A detailed comparison between the realization of Cholesky decomposition and OR method is given, a systolic/wavefront array made of general purpose DSP is used to realize the adaptive beamforming at a moderate speed, and a wavefront array to extract the adaptive weights which is necessary in some applications is designed. In Chapter 5, the author proposed a new structure to realize the space time adaptive processing. First 1~q using the FFr and the truncating infinite sequence and sone optimizing method, a much simpler architecture can be acquired in realizing the three portion of channel processing: quadrature sampling, pulse compression and adaptive equalization.

第五章研究并提出了用全通用DSP模块设计空时二维自适应信号处理机的新方案，首先用快速付立叶变换和对长序列截断处理的重叠保留法以大大减少的运算量完成了处理机通道处理部分的正交插值、脉压、自适应均衡三个功能块的长阶数线性卷积运算，接着对自适应波束形成提出了多种实现方案，分析了多种方案下的运算量和设备要求，指出在不同通道数、不同数据吞吐率、不同自适应要求时这几种方案有不同的可行度和实现难度，并针对实际要求确定了一种运算田N、的实现方案，对自适应波束合成部分的大量贝玉以良元组咸肋冈络结拘和处凰闺和羽凶挝娠昨了优化设计以威少设备复杂性，构成了设备量大夕父伯小、们g团回高、辜于生回阴田闩引愧快的空时二维自适囱戏升引毗四机。

From Cacalia deltophylla (collected from Luqu County, Gansu Province), 22 compounds were isolated, of which 15 compounds have been identified. Among them, two compounds are new. They are named as 3-methyl-4-hydro-8-acetyl-furanonaphth-9-one and 1hydroxy-2-methoxy-3-acetyl-4, 8-dimethyl-5, 8-dihydro-naphthalene.

从采自甘肃省碌曲县的三角叶蟹甲草全草的甲醇提取物的石油醚部分和乙酸乙酯部分中，采用同样方法分离得到22个化合物，鉴定了其中的15个化合物，其中有2个为新化合物，分别命名为3-甲基-4-氢-8-乙酰基-呋喃萘-9-酮（2）和1-羟基-2-甲氧基-3-乙酰基-4，8-二甲基-5，8-二氢-萘（3）。

Leaves basal, distichous; petiole well developed, base sheathing; leaf blade lanceolate or oblong, with several pairs of longitudinal veins parallel to a distinct midvein.

茎非常短。叶基生，二列；叶柄明显，基部具鞘；叶片披针形或者长圆形，有几对平行的纵裂或一个显著的中脉。

Leaves. Result: Extraction temperature had effect on total flavonoids yield, and ethanol concentration had more obvious effect than extraction temperature. The more natural storage time, the less total flavonoids content, and the average descent rate was 24.74% per year. The flavonoids content from Lithocarpus polystachyus Rehd. gathered between August and October was the highest. The total flavonoids content was higher in the new leaves of Lithocarpus polystachyus Rehd.

结果：乙醇体积分数对总黄酮提取量有显著影响，提取温度对总黄酮提取量有影响；多穗柯自然存放时间越长，总黄酮含量越低，平均每年下降24.74%；不同季节采摘的多穗柯其总黄酮含量以8~10月最高；经对怀化多穗柯嫩叶和老叶中总黄酮的提取测定表明，多穗柯中嫩叶总黄酮含量最高，二年生最低。

Long branch is rufous, show "" the glyph bends, smooth, have stipular thorn or not apparent; Short branch is born in the each other on the long branch of biennial above; Fall off sexual rod is finer, without bud, bunch is born on short branch, after autumn and foliaceous all fall.

长枝红褐色，呈&之&字形弯曲，光滑，有托叶刺或不明显；短枝在二年生以上的长枝上互生；脱落性小枝较纤细，无芽，簇生于短枝上，秋后与叶俱落。

Formic acid, hexyl ester and Z-3-Hexen-1-ol were preliminarily confirmed to be the important substances for attracting woolly apple aphid, but 4-methyl-1, 3-pentadiene and Z-3-hexen-1-ol, acetate were not.

初步确定，E-3-己烯－1-醇、甲酸己酯可能是对苹果绵蚜有较强引诱作用的重要物质；4-甲基－1，3-戊二烯、乙酸叶醇酯不是引诱苹果绵蚜的物质。

His plays fall into three categories: tragedies ( Hamlet, Romeo and Juliet, etc.), comedies ( Merchant of Venice, The Dreams of the Midsummer Nigh t, etc.) and history plays Henry VI, Charles II etc.

他的作品分为三类：悲剧、喜剧和历史剧，悲剧有《哈姆莱特》、《罗密欧与朱丽叶》等，喜剧有《威尼斯商人》、《仲夏夜之梦》等，历史剧有《亨利6世》《查理二世》等。

Although Jespersen's theory was formed over 80 years ago,it is still valuable for many fields of linguistic study,such as second language acquisition.

叶氏的语言演进理论自诞生至今虽已经历了80余年历史，但对当代二语习得等研究领域仍有其指导意义。

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。
