Wastewater containing titanium pigment was treated by microfiltration membrane, Nanometer titanium can be purified and concentrated by use of microfiltration. Operational conditions were optimized and the model was built. Finally, the amount of wash water was reduced. Based on the above research, the whole set equipment was designed, which can meet the needs in a titanium industry with a capability of 500 ton per year. Backflush and automatic control were used in the equipment, which has been steadily run two years, has been widely adopted in titanium industry. The technology has been widely adopted in titanium industry.In the recent years, whole set equipment of ceramic membrane was increasingly used in the recovery of desired production from fermentation broth in China. A new membrane process integrated with pretreatment of flocculation or coagulation was exploited to recover Inosine. ZrO2 ceramic membrane was used in the work, and the average permeation flux could reach 150L/m2.h under pH value of 3, transmembrane pressure 0.1MPa, CFV 3m/s, and temperature higher than 70C. The recovery ratio of inosine is higher than traditional recovery method, although inosine degraded under acidic and high temperature condition.

实验表明，ZrO_2膜处理肌苷发酵液的合适条件为pH=3、操作压力为0.1MPa、膜面流速3m／s、温度大于70度，此时可以获得平均渗透通量150L／m~2h，但由于酸性条件、高温下肌苷降解，导致肌苷收率有所降低，但仍高于传统肌苷提取方法得到的收率；为进一步提高肌苷得率，缩短提取工序，实验研究了絮凝剂预处理发酵液，解决碱性条件下由于蛋白析出导致膜污染加重的问题，研究表明采用CaCl_2絮凝并调节pH=11，可以获得平均渗透通量为180L／m~2h，肌苷得率大于95％；比较了三种肌苷提取工艺得到的产品质量，采用预处理与陶瓷南京工业大学博士学位论文膜分离结合的除杂工艺得到的粗昔质量与陶瓷膜分离、离子交换及活性炭吸附工艺生产的粗普质量相当，均优于传统的提取工艺；设计了每小时处理12一巧吨肌普发酵液的陶瓷膜成套装置，采用部分内循环的方式降低设备的能耗，简化了肌昔提取方式，提高了产品的收率和得率，由于减少离子交换和活性炭吸附，使得工厂废水排放量降低30一40%，降低酸、碱用量，有利于环境保护。

The mean preoperative kyphotic angle for the 11 individuals with the thoracic or thoracolumbar burst fractures was 24.6° and the mean preoperative lordotic angle for the 3 individuals with lumbar burst fractures was 10.6°.

平均出血596.4 mL。关于术后并发症，出现一过性神经损伤加重病人1例，假关节形成1例。

The mean outer diameter of the cup was 52 mm (range, 48 to 62 mm). Osteolysis progressed in sixteen (53%) of the thirty hips.

臼杯的平均外径是52 mm（48 ～62 mm）。30例中有16例骨溶解加重。

The patients were followed up for 22.2 months. There were no obvious loss of correction, trunk equilibrium or pseudoarthrosis. No worsened neural symptoms or new irreversible neural functional lesion were found.

术后平均随访22.2个月，无明显矫形丢失、躯干失平衡、假关节形成，且未发生原有神经症状加重及新的不可逆性神经功能损害。

Inflammatory cell infiltration and subserous hemorrhage appeared in 12 and 24 h group.

结果：伤后各组胃黏膜COX2的表达明显高于对照组；实验组各组血浆内毒素水平均明显高于对照组（P.05），于伤后8 h达高峰；伤后各组胃组织出现逐渐加重的胃黏膜下充血、水肿，12、24 h组出现炎细胞浸润、浆膜下出血。

Results: The mean UI in Chongqing district were higher than proper iodide standard defined by international Council for control of iodine deficiency disorders,and the UI in HT groups were significantly increased compared with Con(P.05). The thyrocele and ophthalmopathy in AITD became more and severer accompanying UI increasing, the rate of goiter and endocrine ophthalmopathy in high iodide AITD was significantly higher than PI AITD( P.05).In the meantime, the positive percentage of TGAb and TPOAb also increased evidently in HI compared with PI(P.05).Cytokine IL-1?

结果：三组患者的平均UI水平高于国际碘缺乏理事会规定的适碘范围，HT患者的UI水平较正常人显著升高（P.05）；在AITD患者UI水平的升高伴随着甲状腺肿大、眼部并发症等临床症状的加重，高碘组与适碘组相比差异有显著性（P.05），且随着UI水平的提高，TGAb和TPOAb阳性百分率明显提高，不同UI水平各组间和每两组间有显著差异(P.05)。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.
