From the results of XPS, ESR and coloration feature, it was inferred that N was embedded into TiO_2 powders to form interstitial and substitutional N doping,and N doped in the part of oxygen vacancy was crucial to emerge visible-light activity. Moreover, N doping played a significant role in restraining reoxidation of oxygen vacancy.

XPS、ESR测试结果和粉体的显色特性表明：N元素可以由沉淀剂直接引入到TiO_2粉体中，形成间隙型和置换型N掺杂；N占据氧空位的位置对粉体的可见光吸收特性是必要的，同时氮掺杂还可抑制氧空位的再氧化。

The function of 3dB fiber loop mirror in fine wavelength partition is studied. With this theory, a novel narrow linear band, dual-wavelength switchable Er-doped fiber laser is realized.2. An unpumped Er-doped fiber and broadband fiber Bragg grating with high reflectivity is served as an auto-tracking filter, where the space hole-burning effect appears when the laser signal travels and forms standing wave, thus the generation of multi-longitudinal-mode is suppressed. Then the high birefringence fiber loop mirror is introduced to act as comb-liked wavelength filter.

For the first time, we found that the EHFV propagated in HUVEC has a potentiating stimulation to ET-1 and PGI〓 secretion , which may be respensible for the increased plasma ET -1 level and PGI〓 concentration in patients with EHF during the early phase of the disease.

我们的研究结果提示，HUVEC对EHFV敏感，EHFV感染未引起HUVEC的细胞病变，但可抑制HUVEC的增殖，这有可能改变EC的基因调节，或低调，如Ⅷ R：Ag合成障碍，引起止血功能异常；或高调，如主要组织相容性复合物Ⅱ型抗原、干扰素β和内皮细胞白细胞粘附因子的表达增加，增强EC的炎症反应。

This is believed to be conneeted with the depletion of Mo, a scavenger of P, in matrix due to the Mo tithed carbides formation during preaging. Therefore, more P is released and segregated to grain boundaries. Carbide coarsening perhaps contributed to the increment in transition temperature too.

Mo可抑制磷的偏析，但因时效过程中富Mo碳化物的生成和长大，使基体中Mo的含量降低，因此，磷从Mo的&束缚&下&解放&出来并偏析到晶界，使脆性转变温度升高，此外，碳化物的粗化也可能导致脆性转变温度升高。

Cells from the resulting soup were placed in a biodegradable polymer scaffolding and implanted in the abdomens of immunosuppressed rats, close to blood-rich tissues.

需提醒的是，患者在服用此药物的同时，不宜使用可抑制尿酸排泄的降压药物，如噻嗪类利尿剂、含噻嗪类利尿剂的复方制剂以及水杨酸类药物，以防止高尿酸血症的发生。

The long-term and short-term effects of different propionic/acetic acid ratio and initial pH on the anaerobic and aerobic transformations of GAOs were studied.

2在丙酸和乙酸的碳摩尔浓度相同的情况下，GAOs吸收乙酸的速率较快，且在乙酸浓度适宜的情况下，GAOs对乙酸的吸收不需要长期驯化，短期提高进水中的丙酸量可抑制GAOs的生长。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.
