国际上船舶报废制度已建立多年，我国在七、八十年代对国有渔业船舶制定过折旧率，钢质渔船每年折旧率5呢，木质渔船的折旧宰为m阮。

The results are listed as following :㏕he best anti-erosion proportion of resin present is 25wt% in the condition of silicon carbide reinforced SMCC, while the alumina reinforced SMCC is 40wt%.(2) The better anti-erosion results was achieved with the ratio of silicone resin to acrylic resin containing hydroxy being 3: 1.㏕he composites coating tends to be more brittle when added in alundum particles. It also means that the maximum erosion peak of alundum reinforced SMCC tends to normal angle.甌he change of erosion rate of SMCC can be divided into two stages with the increment erodent velocity: the slow erosion stage of the beginning and the stable erosion stage.

首次发现：①SiC增强的复合涂料涂层，树脂含量为25wt％时，具有最佳耐冲蚀性能：Al_2O_3增强的复合涂料涂层，树脂含量为40wt％时，具有最佳耐冲蚀性能；②SiC增强的涂料，有机硅树脂与丙烯酸树脂的比例为3：1时的耐冲蚀性能好于1：1的复合涂料涂层；③Al_2O_3增强体使涂层变脆的倾向大于以SiC为增强体的涂层，即SiC增强的复合涂料涂层的最大冲蚀率出现在30°，Al_2O_3增强的复合涂料涂层的最大冲蚀率出现在75°～90°之间；④低速冲蚀磨损机理主要是弹性变形与疲劳；高速冲蚀磨损机理主要是显微切削和显微犁耕。

In comparison, the period of aerobic ammoniation is shorter and NH3-N peak value is lower (the rate of net increase can reach 33 % only).

The results indicate that, with HRT of 8?h and temperature of 35℃, the COD removal rate is beyond 80%, the removal rate of TN about 8%, the ammonification rate of organic nitrat.

试验表明：厌氧附着膜膨胀床反应器处理乳品废水，在水力停留时间为8h、中温35℃条件下，COD去处率达到80%以上，对总氮的去除约为8%，出水有机氮的氨化率达70%以上，ρ/ρ由进水的0 5提高到0 8以上。

The characteristics of nitrogen fixation, ammonification , nitrification and denitrification in coastal zones;2. Study on ammonification rate and slow release performance of urea;3. The results indicate that, with HRT of 8?h and temperature of 35℃, the COD removal rate is beyond 80%, the removal rate of TN about 8%, the ammonification rate of organic nitrat.

Adjusting pH to 12, air-liquid ratio to the range of 3 000～4 000 and temperature to the range of 35～45℃, after the washing wastewater from deposited ammonium carbonate that the initial concentration of ammonia nitrogen was 1 570 mg/L was treated by ammonia stripping, the residual concentration of ammonia nitrogen was controlled to below 100 mg/L and removal efficiency reached to over 94%.

发现pH、温度和气液比是氨氮去除效率高低的关键因素，废水初始浓度对去除率无影响。调节废水pH=12，气液比在3 000~4 000，温度在35~45℃范围，浓度为1 570 mg/L的碳铵沉淀洗涤废水经氨吹脱处理可使出水残余氨氮浓度控制在100 mg/L以下，去除率达94%以上。

The effects of the ratio of water and the sample, extracting temperature, extracting time, and the sample particle size on water-soluble active ingredients of Ampelopsis grossedentata were investigated with single factor and orthogonal experiments as a measure of total flavones and water extraction ratio.

以水溶性活性成分总黄酮和水浸提率作为衡量浸提效果的评价指标，分别采用单因素和正交实验L9(34)确定了茶水比、浸提温度、浸提时间和样叶粒度对显齿蛇葡萄总黄酮和水浸提率的影响，得出了影响的主次顺序为茶水比、浸提温度、样叶粒度和浸提时间。

Objective: To investigate the clinical characteristics of primary hyper-parathyroidism with amyotrophy.

文章摘要：目的：探讨原发性甲旁亢伴肌萎缩临床特点，提高临床医师对本病认识，降低误诊率和漏诊率。

The levels of schistosome circulating cathodic antigen in serum and urine were detected parallelly by McAb-Dot-ELISA. In 81 acute cases, the positive rates in serum and urine were 96.30% and 66.67%(P＜0.01) but the combined positive (positive in serum and／or in urine) rate reached 100%, while in 109 chronic cases, they were 77.06% and 10.09%(P＜0.01) but the combined positive rate was not increased. In 100 healthy individuals from non-endemic areas, no positives were detected in serum and urine with false positive rate of 0%. The cross reaction rates in serum and urine of 51 cases with clonorchiasis were 9.43% and 0% but all were 0% in 48 cases with ancylostomiasis.

The overall neural tube defects rate was 10.63 per 10 000 births, and rates were higher (18.99 per 10 000 births) in the year 1993, lower (6.05 per 10 000 births) in 1998. The prevalence rates of anencephaly, spina bifida and encephalocele were 4.71 , 4.39 and 1.53 per 10 000 births respectively.
