The overall neural tube defects rate was 10.63 per 10000 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.

结果：在1993～2000年间，共监测到1 189 126个活产儿和死胎、死产儿出生，其中有明确诊断的神经管畸形儿1 264例；总出生人群中的神经管畸形率为10.63/10 000，1993年的畸形率最高(18.99/10 000)， 1998年最低(6.05/10 000)；无脑儿、脊柱裂和脑膨出在每10 000个出生儿中的患病率分别为4.71、4.39和1.53。

To characterize the distribution of blood pressure, prevalence, and risk factors for hypertension in pediatric chronic kidney disease, we conducted a cross-sectional analysis of baseline BPs in 432 children (mean age 11 years; 60% male; mean glomerular filtration rate 44 mL/min per 1.73 m2) enrolled in the Chronic Kidney Disease in Children cohort study. BPs were obtained using an aneroid sphygmomanometer.

为了描绘血压的分布，流行和引儿童慢性肾功能不全引起的高血压的危险因子，我们对432名患有慢性肾功能不全的儿童的血压进行了一项有代表性的配伍研究（平均年龄为11岁，60%为男性，平均肾小球滤过率为44ml/min1.73m2）血压的测量是利用无水银血压计进行的，而肾小球滤过率则是根据碘海醇的清除率来测定。

If the advance angle of injection is adjusted too earlier, knock phenomenon will been show in the combustion process. EGR is a good way to improve NOx emission. If EGR is big, the ignition delay period will become long.

EGR率是改善NOx排放的有效手段，EGR率大的工况，滞燃期长，达到着火条件前，SMD在零附近的油滴更多，则汽化表面积越多。

Based on Rice fading channel, and taking the effect of bit error rate of the angle of elevation of satellite coverage into account, A bit error rate formula and computer simulation figures are given.

以莱斯衰落信道为基础，考虑卫星覆盖仰角对误码率的影响，推导了误码率的解析表达式。

Air permeability of field soil was obtained k1=4.8446×10^(-12)m^2 by soil column method. Meanwhile, relative permeability curve of air-water was gained by biphase flowing experiment. During experiment period, average of soil water content was 0.2689g and pH value was 7.0-8.5. The quantity of aboriginal animalcule went down sharply after pouring contamination into the ground and then rose gradually to its original level which was 10^7 (unit g1dry soil).

采用土柱法测得现场土壤的空气有效渗透率为k1=4.8446×10^(-12)平方公尺，通过气液两相流动试验得到气－液相对渗透率曲线；试验期间土壤平均含水量为0.2689g，pH值在7.0-8.5之间；微生物含量在注入污染物及营养盐后先下降后回升，驯化后期细菌密度达10^7（个g^(-1)干土）数量级。

Moreover, aiming at the complex geological characteristics such as the heterogeneity and anisotropism, etc. of low-resistivity oil/gas reservoirs, the statistics model method and artificial neural network model method are introduced in the low resistivity oil/gas reservoir interpretation and evaluation for the first time.

另外，针对各种低电阻率油气储集层的非均质性和各向异性等复杂地质特征，第一次把统计模型方法和人工神经网络模型方法引入到了低电阻率油气储集层解释与评价之中，并建立起了一套相应的测井解释与评价方法。

In NO 1 unit, 187% of naphthalene, 71% of anthracene and 76% of fluoranthene can be filtered. In NO 2 unit, 96% of naphthalene, 42% of anthracene and 38% of fluoranthene can be filtered.

工艺1 中的萘、蒽、荧蒽等滤后水较原水去除率分别为87%、71%和76%；工艺2 中萘、蒽、荧蒽等滤后水较原水去除率分别为96%、42%和38%。

Wtp53 has obvious antiblastic effect towards Y79 cells, and the apoptosis rate of Y79 cells was the highest after transfection mediated by ultrasound-microbubble.

结论wtp53基因对RB瘤细胞具有较明显的抑制生长的作用；质粒+微泡+超声辐照，质粒+脂质体转染，以及质粒+超声辐照，均可促进Y79细胞的凋亡，但超声微泡介导的转染引起的凋亡率高于脂质体转染，而二者的凋亡率又明显高于质粒+超声转染。
