结果表明，沙尘暴发生当天（滞后0d）儿童各种所查症状发生的相对危险度均有不同程度地升高，沙尘暴过后（滞后1~5d），儿童各种症状的RR逐渐降低，沙尘暴过后4d（滞后4d），几乎所有症状均恢复正常。

The lag correlation indicates that the eastern Pacific SST in winter correlates with the WPSH anomaly two or three months later to the highest degree; the SST in the tropical Indian Ocean and the WPSH anomaly in the corresponding period significantly correlates with each other in winter; and the SST in the western Pacific in winter and spring negatively correlates to the WPSH anomaly in the corresponding period.

选取各关键海区分析海温与西太副高在不同时段上的超前滞后相关，结果表明，冬季东太平洋海温与滞后其2—3个月的副高异常达最大正相关，热带印度洋海温异常与冬季同期副高异常的正相关最显著；西太平洋海温在冬春季与同期的副高负相关最显著；北太平洋海温在冬春季滞后副高1—2个月时存在负相关，大西洋暖池区6月与西太副高的同期正相关最大；对南太平洋来说，冬季的西太副高与从前秋到春季的SST都存在最大负相关。

Hence the propagation delay time of master's control signals don't need to be pre-known in the control process of synchronization, and also these criteria are applicable to chaotic complete synchronization of the master-slave Lur'e systems concerning master's control signals without propagation delay.

我们证明了关于该混沌同步问题达到滞后同步或不能达到滞后同步的四个Lur'e型判据和七个频率域判据，给出了优化选择主系统驱动变量的模型。

Results show that floes' VC and D at the surface water were closely related to current velocity; and the peaks of VC lag those of the current velocity. The lag variation during ebb and flood tides is 10-30min and 30-50 min, respectively. Current velocity at 50 cm/s is a turning point of D vs. vertical average current velocity, before the point, Dm increases with current velocity, and decreases after the point. Similarly, VC at 75μl/L becomes a critical point in the surface water, below the point, D increases with VC, and above the point, D stabilizes.Δp is D dependent, larger floes have much lower Δp than smaller floes. Both D and Δp of floes affect ω. In the surface water during spring tide and neap tide, a power exponent relationship exists between Δp and D, and ω and D.

研究表明：①长江口徐六泾表层絮凝体体积浓度主要受水流流速影响，再悬浮现象明显，体积浓度过程线滞后流速过程线，落潮期间滞后10-30min，涨潮则滞后30-50min；②小于一定流速时絮凝体平均粒径随流速增大而增大，大于一定流速时絮凝体平均粒径则随流速增大而减小，徐六泾夫、小潮表层絮凝体在50cm/s的垂线平均流速时出现平均粒径与垂线平均流速关系的转折；③徐六注大、小潮表层絮凝体平均粒径在体积浓度75μl/L时出现平均粒径与体积浓度关系的转折，体积浓度小于75μl/L时粒径随体积浓度增加而增大，超过75μl/L时粒径随体积浓度的增加变化不明显；④絮凝体有效密度由粒径大小控制，粒径大，有效密度小，反之亦然，粒径和有效密度共同决定絮凝体静水沉速，有效密度和沉速与平均粒径之间均存在良好的幂指数关系。

According to the actual realities, the paper has also put forward some problems and difficulties that the undeveloped areas of the West and Centre of China arc suffering. These problems and difficulties include retard in ideology, stagnation in thinking, unsoundness in product structures, shortage in fund, retard in infrastructure construction, backwardness in education and technological development.
