Changes of erosion and accumulation of the seabed before and after the project The general characteristics of the pattern of erosion and accumulation of the seabed near the scheduled project both before and after the scheduled project are as the following: accumulation occurs at the areas lower than–10 isobath; some suspended sediment is deposited near the coast due to the relatively small tidal current with a monthly accumulation rate of 2-6 mm; while a slight erosion occurs in the areas deeper than–10 isobath with a monthly accumulation rate of .2 mm.

5工程前后海底冲淤变化工程前后海底冲淤相同的地方是：大致沿-10m等深线向近岸呈淤积状态，近岸由于潮流流速小，一些悬沙落淤，月淤积量在近岸附近约2-6mm；而-10m等深线以深基本上呈轻微冲刷状态，月冲刷量一般在0.2mm以下。

Their sex proportion、pretransplant Hb、pre- and post-transplant BP、diuretic therapy、immunosuppressive drugs、native kidney nephrectomy、pre-transplant lymphotoxin cross test and prePTE S cr/BUN were recorded and analysed. The results showed that those nonAza treated hypertensive male recipients with higher pre-transplant Hb and excellent allograft function were susceptible to PTE.

However, the relationship between skin temperature regulation over the area with trigger points and referred pain is still unknown. Therefore, to implement the use of infrared thermogram as a plausible tool for the clinical assessment of referred pain in MPS and treatment assessment, current study will propose a human experiment based on the thermo-changes in skin temperature for patient with MPS.

方法首先是将筋膜炎症候群与正常成人对照观察在颈椎做触诊矫正治疗前后二组受试者所侦测到的皮肤表面温度与视觉分析痛觉、颈部关节活动度、激痛点疼痛阀值等资料作前后比较分析其差异性。

At the same time the pathological examination was made on aorta artery.results zexie grain decreased obviously the levels of serum tc, ldl and mda, increased the activity of sod, and decreased the area and thickness of athermanous plaque in experimental animals.

结果 泽泻颗粒高、低剂量组tc、ldl、sod给药前后差值与模型对照组比较差异均有统计学意义（p＜0.05）；泽泻颗粒低剂量组tg、hdl、mda给药前后差值与模型对照组比较差异均有统计学意义（p＜0.05）。且泽泻颗粒低剂量组的主动脉内膜增厚程度及结缔组织成分均较模型对照组轻。

METHODS:Two hundred and seventy-one eyes of 219 patients with hard nucleus cataract, grading level IV or V, were operated with anteroposterior interceptive chop method for splitting the nucleus, and then with phacoemulsification. RESULTS:The hard nucleus of the 271 eyes were successfully routed. The average phaco time was 57.4 s.
