It is founded that the specific surface area and the microvolume is increased, and the affinity of adsorbent surface for nitrogen is enforced except the modificated activate carbon with alkali.

研究发现，除碱改性活性炭纤维外，改性后活性炭纤维的BET表面积增加、微孔容量增大、对氮气的亲和力增强。

It is found that the specific surface area and the microvolume are increased and the affinity of adsorbent surface for nitrogen is enforced for all the modificated ACF except the modificated activate carbon with alkali. Microwave radiation is proved to be a simple method to increase the surface area.

除碱改性活性炭纤维外，改性后活性炭纤维的BET表面积增加、微孔容量增大、对氮气的亲和力增强，尤其是微波辐射法可使BET表面积大大增加。

The technological methods and optimal combination ratio were studied in the present paper, involving protection of natural color, elimination of bitter taste, mixtion and stability of the beverage. By single factor trial and orthogonal test, we optimized the processing techniques: Using 100mg/kg Zinc gluconate and 0.1% Calcium hydroxide as the color protection agent, burned in 80℃for 2min. The natural green color of material can be protected effectively.

通过单因素考察及正交实验设计确定了优化后的饮料制作工艺：以100mg/kg葡萄糖酸锌和0.1%氢氧化钙为护色剂，在漂烫温度80℃，漂烫时间2min条件下，有效地保持了苦瓜原料特有的绿色；以苦瓜皂苷为功能强化因子，以1.25%海藻酸钠为包埋剂，通过锐孔-凝固浴法对苦瓜原汁和苦瓜皂苷进行包埋；使用8%木糖醇、0.3%β-环状糊精、15%苦瓜汁和10%苦瓜胶囊对饮料进行调配，很好地保持了苦瓜特有的苦香味和口感；以0.15%黄原胶、0.2%琼脂、0.05%羧甲基纤维素钠复配方式，来增加饮料的稳定性。

The toxicity and the osteogenous ability on the surface of PCHA: the toxicity was examined by coculture with PCHA to record growth of cells with MTT method. The osteogenous ability was investigated by observation of the formation and growth of cells on the surface of PCHA bone cement.

PCHA毒性检测和表面细胞活性的观察：将PCHA浸出液与骨髓基质细胞共同培养，通过MTT比色描记细胞生长曲线，快速判定制孔剂添加后PCHA的毒性反应；将PCHA制成标准试件，与骨髓基质细胞共同培养，观察细胞形态和生长活性。

RESULTS: The time of misplacement of pedicle screw was 5-69 days with an average time of 18.5 days, including 7 cases of screw penetrating into lateral cortex, 4 of screw penetrating into medial cortex, 2 of screw penetrating into pedicle cortex, 2 of overplacement, 2 of intervertebral foramen placement and 2 of intervertebral space placement.

结果：患者自螺钉置入后至发现椎弓根螺钉误置时间为5~69 d，平均18.5 d。其中螺钉穿破椎弓根外侧皮质7例，穿破椎弓根内侧皮质4例，螺钉穿破椎弓根皮质2例，螺钉置入过深2例，螺钉进入椎间孔2例，进入椎间隙2例。

The heavy silicone oil Oxane HD is effective and safe to treat complicated retinal detachment, especially with holes located in the inferior and posterior pole.

重硅油Oxane HD作为眼内填充物可以有效安全地治疗复杂性视网膜脱离，尤其是伴下方或后极部裂孔的视网膜脱离。

Pollen grains germinated soon after pollination. Pollen tubes grew first into the intercellular space of branched penniform stigma and then through the intercellular space of transmitting tissue into the top of the ovary, further penetrating the ovary wall and primine to the micropyle. Green fluorescence was found in both pollen and pollen tubes.

结果表明：授粉后，花粉随即萌发，花粉管进入羽毛状柱头分支结构的细胞间隙，继续生长于花柱至子房顶部的引导组织的细胞间隙中，而后进入子房，在子房壁与外珠被之间的缝隙中向珠孔方向生长，花粉与花粉管均具有明显的绿色荧光。
