The pore size decreases while the thickness and charge density increase with the increase of monomer concentration. the pore size of Na_2SO_4 rejection ranges negligibly when reaction time prolongs, while thickness and charge density increase.

考察了中空纤维纳滤膜对不同浓度的NaCl溶液的分离性能，结果表明复合膜对NaCl的截留率和通量都随盐溶液的浓度增加而降低。

Surveillance: evaluation by a nephrologist every 3-6 months depending upon the severity of renal impairment; ophthalmologic evaluation every 1-2 years; assessment of bone mineralization throughout the disease course; every 2-3 years fasting blood glucose concentration and testosterone concentration (in males starting before puberty); routine monitoring for late-onset complications in poorly treated adults.

监控：每3－6个月（视肾脏损坏严重程度而定）由肾科医生评估；每1－2年由眼科医生评估；在整个病情发展过程中评估骨矿化程度；每2－3年禁食一次降低血葡萄糖浓度和睾酮浓度；在治疗不当的成人中进行迟发性并发症的日常监控。

The effects of equilibrium time,acidity of the solution,temperature,concentration of redox reagents on the adsorption of neptunium by silica gel were carried out.

进行了吸附平衡时间、酸度、温度、氧化还原剂浓度等条件对硝酸溶液中Np、Np和Np在硅胶上吸附的影响的实验，与吸附时同酸度条件下的洗脱实验，用浓度为3mol／L的硝酸作为解吸剂的解吸实验。

61Healthy persons were selected as healthy group. The serum concentration of TGF-β1 was measured by ELISA method; nitre oxide was measured by nitrit reductase method, plasma Ang II was measured by radioimmunoassay.

对高血压病人和61例健康对照者应用酶联免疫吸附法测定血清TGF-β_1浓度，硝酸还原酶法测定NO的浓度，放射免疫分析法测定Ang Ⅱ水平。

Through analyses of the field tracer migration test results of tritium in unsaturated loess located in semi arid area, it is found that the longitudinal concentration distributions of 3H are symmetry at higher relative concentration and non symmetry at lower relative concentration.

通过氚在黄土包气带现场示踪试验结果的分析，发现3H纵向分布在相对浓度较大时是对称的，而相对浓度较小时则不对称。

These relative risks did not change significantly after adjustment for age; sex; total cholesterol, low-density lipoprotein cholesterol, or triglyceride levels; carotid-wall thickness; smoking status; the presence or absence of diabetes and systolic and diastolic hypertension; body mass index; and other risk factors. In women, Lp lipoprotein levels were not related to cardiovascular risk, even after adjustment for estrogen use or nonuse.

这些相对危险性经过年龄、性别、总胆固醇、低密度脂蛋白胆固醇、或三酸甘油酯浓度、颈动脉管壁厚度、吸烟状态、糖尿病和心脏收缩及舒张高血压的有无、身体质量指数、和其他的危险因子的调整后并没有显著改变，而在女性方面，Lp脂蛋白浓度与心血管风险无关，即使经过雌激素有无使用的调整后也是如此。

The object of this study is to cancerous and normal cells intimacy of hematoporphyrin derivative for diagnosis and therapy cancer, fluorescence spectra of cancerous and normal cells are measured using a ultrashort pulses laser spectral technique and picosecond time-correlated single-photon counting system.

研究用于癌症诊断与治疗的光敏剂血卟啉(hematoporphyrin derivative， HPD)对人体癌细胞与正常细胞的亲和性，采用超短脉冲激光光谱技术和皮秒时间相关单光子计数系统，测量经血卟啉培养的活体癌细胞与正常细胞的荧光光谱，观测到癌细胞样品在创645nm处具有特有的光谱谱峰；测量不同浓度血卟啉荧光光谱，观测到随着血卟啉浓度的逐渐增大，在645nm处出现的光谱峰也随之显著增强。

The high-resolution dispersion simulation results indicate that the air pollutants from Nuclear Power Plants 1 and 2 enter Taipei and reach the western basin after 2h with the concentration reduced to one-hundredth in the case of prevailing northeasterly wind.

在冬季东北风的个案(96/12/01)，核一厂、核二厂的瞬间污染物大约在2小时后，即进入台北盆地到达西侧，此时浓度大约是初始浓度的百分之一。

Methods We adopted four methods that single cpidural block anesthesia or narcotics analgesies were injected into subarachnoid space and epidural space or single narcotics was injected into subarachnoid space (group C fentanly 25μg;group D fentanly 20μg) to study analgesia birth for 130 nullipara women. The analgesia efficacy, side effect, birth time md mode,postpartum haemorrhage and the condition of the fetus and the newborn were compared.

采用单纯硬膜外腔阻滞、蛛网膜下腔-硬膜外腔联合给予低浓度麻醉药及镇痛药、单纯蛛网膜下腔给予低浓度镇痛药(C组芬太尼25μg，D组芬太尼20μg)等四种不同的方法对130例初产妇进行分娩镇痛，比较几组的镇痛效果、不良反应及对产程、分娩方式、产后出血、胎儿及新生儿等的影响，并与40例正常未干预组产妇比较。
