面向交通土建工程的网络化移动勘测办公系统

现今的交通土建类大型工程项目数据繁冗复杂。传统的数据处理方式速度慢、精度低,已不能满足大型工程管理的需要。GeoNMOS软件可弥补在大型工程项目中数据处理方面的不足。文中提出网络化移动勘测办公系统的设计理念,着重分析GeoNMOS各个模块的特点及其主要功能。

Isolation, cloning and sequencing of AFLP markers related to disease-resistance traits in Fenneropenaeus chinensis

Amplified fragment length polymorphisms （AFLP） technique was used to analyze the fingerprinting of four successive generations of Fenneropenaeus chinensis to reveal their disease-resistance traits. Some loci showed quite different genetic frequencies due to artificial selection, which implied that these fragments were putative markers related to the disease-resistance trait. We developed a simple and effective method to further characterize these AFLP fragments. Specific AFLP bands were cut directly from polyacrylamide gels, re-amplified, cloned and sequenced. Eight putative genetic markers were sequenced and their sizes ranged from 63 to 209 bp. The sequences were submitted to dbGSS （database of Genome Sequence Survey）; and the BLAST analysis showed low similarity to the function genes, indicating these markers were tightly linked to a disease-resistance trait but were not functional genes.     

韩国建设用地整理是如何做的?

韩国的建设用地整理又叫土地重整,起始于1934年日本殖民时期.城市化进程的加快使韩国的城市人口急剧增长,城市人口所占比例从1950年的26.7%增长到2000年的87.8%.这使得发展不平衡的同时,必须提供更多的城市服务项目及大量的住宅单元.     

ESR DATING OF FLUVIAL SEDIMENTS USING GE CENTER IN QUARTZ

Using the Ge centers of quartz sediments, the buried ages of fluvial sediments were determined by ESR technique. The ESR ages obtained from Ge centers are consistent with the TL ages, correspond with their horizons, accord with the geological background, and every ESR age is available. In this paper, determination of total dose of natural radiation (TD) and the reliability of ESR age using Ge center are also discussed.
