向百亿支柱产业冲刺——襄樊市建委副主任黄潮海谈做强做大建筑业

日前召开的襄樊市工程管理工作会议确定——2010年全市建筑业总产值达到100亿元。对于这一硬性指标，襄樊市建委副主任、高级工程师黄潮海在接受本刊记者专访时表示：只要坚持以科学发展观为统领，以工程质量、安全生产、市场规范、技术创新为重点，工程建设管理工作就能协调发展，建筑业总产值冲刺100亿元也就指日可待!

Vertical motions of tide gauge stations near the Bohai Sea and Yellow Sea

A modified Gauss-Markov model with weighted constraints was constructed by combining satellite altimeter and tide gauge records. Vertical motion rates of nine tide gauge stations around the Bohai Sea and Yellow Sea are estimated. This is the first time systematic estimates have been derived in this region. Downward trends were seen at the six tide gauge stations located at Tanggu, Longkou, Laohutan, Bayuquan, Xiaochangshan, and Yantai; with vertical motion rates of-1.82±0.50,-1.65±0.46,-0.88±0.42,-0.58±0.62,-0.13±0.43, and-0.01±0.43 mm/yr, respectively. Upward trends were seen at the three tide gauge stations located at Qinhuangdao, Huludao and Chengshantou; with vertical motion rates of 1.12±0.46, 0.55±0.49 and 0.26±0.44 mm/yr, respectively. There was significant subsidence in Tanggu and Longkou, and a rising trend in Qinhuangdao. According to our results, the rate of sea level rise calculated from these tide gauge records can be improved using a more accurate measurement of the land elevation accounting for lifting or subsidence. The model derived can be used to estimate vertical motions of tide gauge stations, and can be widely applied to revise the benchmark levels of tide gauges.

刺参的病害与防治

化皮病 患病稚参发病初期，活动能力弱，附着力也相对弱，摄食不活泼，继而身体收缩，变成乳白色球体，并伴随着局部溃烂，骨片倾倒，脱落，而后溃烂面积逐渐扩大，全身解体死亡。在附着基上，有时会发现浅红色片状区域(细菌感染区)，在该区域的稚参，身体也显浅红色，病变和死亡情况同上。随着细菌感染区的扩大，稚参死亡数明显增加。溃烂病主要是细菌感染蔓延所致，稚参患病的机会，可能与稚参的活动和个体有关，活力强，个体大的稚参，不容易感染；活力弱，个体小的稚参，尤其是5毫米以下的稚参，容易感染，患病，死亡。
