查询词典 si

The present invention relates to an ultraviolet detector and manufacture method thereof, in which a buffer layer is formed on a baseplate and a P-type GaN layer is formed on the baseplate by using epitaxial method. By availing ion-distribution-and-vegetation technology, a first N-type GaN layer is vegetated and invested in the P-type GaN layer by distributing and vegetating Si.sup.+ ions in that layer, and a second N-type GaN layer having a thicker ion concentration is invested in the N-type GaN layer.

专利简介本发明系关於一种紫外光检测器及制程方法，其主要系在一基板上形成一缓冲层，利用磊晶法在缓冲层上形成一P型氮化镓系层，并接著以离子布植技术将Si+离子适当地布植於该P型氮化镓系层中，形成一N型氮化镓系层及包覆在此N型氮化镓系层中且布植浓度更高的另一N型氮化镓系层，最后在该P型氮化镓系层及第二N型氮化镓系层上分别镀上一环状金属层及另一金属层，以作为欧姆接触层。

The individual density was 4.77 inds. per gram dry soil. The results indicated that the number of soil nematode fluctuated significantly with season, the number of soil nematode in autumn is significantly more than that in summer and in spring. Shannon-Wiener index, Pielou index, Margalef index and Trophic diversity index were used in analyzing the diversity of nematode community, ranking Cc＞Pm＞Clc, while Simpson index ranking Pm＞Clc＞Cc. The value of f/b, MI index, PPI index, MMI index, MI2-5 index, SI index and EI index were used in analyzing the characteristics of the functional structure of the nematode communities, ranking Cc＞Pm＞Clc, while PPI/MI value ranking Clc＞Pm＞Cc. It showed that the Clc was disturbed significantly.

研究结果表明，土壤线虫数量存在明显的季节波动，秋季明显高于夏季和春季；土壤线虫群落多样性指数、均匀度指数、丰富度指数和营养类群指数大小依次为阔叶林、针叶林和混交林，而优势度指数却表现为：针叶林＞混交林＞阔叶林；土壤线虫群落营养类群f/b值、MI 指数、PPI 指数、MMI指数、MI2-5指数、SI指数和EI指数均表现为：阔叶林＞针叶林＞混交林，而PPI/MI指数则表现为：混交林＞针叶林＞阔叶林，表明混交林受干扰明显；土壤理化特征与线虫数量、属数、生态指数间也存在明显相关关系。
