Results 86 cases of polyacrylamide hydrogel were injectable implant in the treatment of non-organic change. 32 cases only because of psychological pressure,and urgent requirement for seeking out hydrogel,Were treated using suction liposuction methods.Induration significantly complicated and tough for using semi Central areolar incision under half,pumping out water gel thoroughly Abstract induration.Hydrogel into pectoralis major,who may armpit transverse incision after augmentation.

结果：86例聚丙烯酰胺水凝胶注射式隆乳术后的就诊者中，对无明显器质性改变，仅因心理压力过大而迫切要求取出水凝胶的32例求术者，采用脂肪抽吸式方法抽吸；对于并发硬结明显大而硬者，采用乳晕下1/2半环切开，抽吸水凝胶彻底摘出硬结；水凝胶注入胸大肌内、后间隙者可采用腋下横切口，分离胸大肌将乳腺后间隙水凝胶向胸大肌下间隙挤出抽吸到清亮液体后，同期放入假体于胸大肌后间隙。

Among his examples are vampire bats tuned to extract blood from large slumbering mammals and bats that aim instead for the warm breast plates of birds; New World leeches that track their hosts through the water and Old World leeches that relentlessly stalk down blood bearers on land; the notorious vampire finches of the Galapagos that daintily peck open dribbling wounds on the hindquarters of blue-footed boobies; and the candiru, tiny, eel-like catfish that are reputed to have the power to swim up a person's urethra and suck blood from the bladder and thus are often more feared than their fellow river dwellers, the piranhas.

他举的例子有自静止状态的大型哺乳动物吸血的吸血蝙蝠，与转而瞄准鸟儿温暖胸脯的蝙蝠；西半球的水蛭透过水来找寄主，东半球的水蛭在陆地上无情追踪带血的对象；加拉巴哥群岛恶名昭彰的吸血鸣鸟一点一滴优美地在蓝脚鲣鸟的尾部啄出伤口；还有短小鳗形的寄生鲶，以直接游入人类尿道从膀胱吸血而知名，因此比同条河里的食人鱼更令人畏惧。

Because suck fat to be confined to hypodermic and adipose layer, this do not have old blood vessel and main nerve, because this won't be hurt,reach blood-vessel and nerve, and " resonance sucks fat " do not need puissant negative pressure to suck fat, together with undertook to sucking fat tube head meshy safety is entered surely, effectively protective blood-vessel, nerve is not damaged.

因为吸脂仅限于皮下脂肪层，该层没有大血管和主要神经，因此不会伤及血管和神经，并且&共振吸脂&不需要强力的负压吸脂，加之对吸脂管头进行了网状安全必进，可以有效地保护血管。神经不受损伤。

Sera of human infected with Clnorchis sinensis (509 cases), Opisthorchis viverrini (47 cases), Paragonimus westermani (20 cases) Schistosoma japonicum (14 cases) and serum of 163 healthy students were used for ELISA.

方法制备华支睾吸虫的粗抗原和分泌-排泄抗原，以ELISA方法对华支睾吸虫感染患者509人、麝猫后睾吸虫感染者47人、卫氏并殖吸虫感染者20人、日本血吸虫感染者14人以及健康人血清163人，检测血清特异性IgG。

Is in the children will eat only after the chewing gum to him because a chewing gum at the same time in order to smoke and a smoke on the out, this is the method of governance otitis media, or ear of pus well after the ear is more pus in this way will be a suction aspiration.

是在宝宝会吃口香糖之后才给他用，因为得在嚼口香糖的同时才能吸而且一吸就出来，这是治中耳炎的方法，即外耳的脓好了之后，在耳膜后还有脓用这种方法一吸就会被吸出。

The influence of nanocrystalline particles and catalysts on the hydriding and dehydrogenating properties of magnesium-based hydrogen storage materials are summarized in this paper.

总结了纳米晶、催化剂改性等对镁基储氢材料吸放氢性能的影响，介绍了不同镁基储氢复合材料的吸放氢性能以及基于密度泛函理论的第一原理计算方法在镁基储氢材料吸放氢性能方面所做的一些基础理论研究，指出随着量子化学、凝聚态物理等学科以及计算机技术的发展，理论计算方法在研究镁基储氢材料吸放氢性能方面的作用将越来越重要。

The results show that:(1) lower concentration or lower initial pH of citrate solution results in a better desorption efficiency;(2) sparging inert gas or adding surfactants into the liquid can lower the viscosity of the solution and the cavitating threshold, and raise the desorption efficiency of SO2;(3) by comparing the experimental results and theoretical analyses , it was concluded that the experimental results are in accordance with the theoretical analyses.

结果表明：(1)在柠檬酸钠浓度较低，或者柠檬酸钠溶液初始pH值较低的条件下均能产生较好的解吸效果；(2)少量惰性气体的通入或者表面活性剂的加入能够降低溶液黏度，产生空化效应，从而提高了SO2的解吸率；(3)通过对比实验证明解吸结果与理论分析相吻合，其研究结果为SO2的深度解吸提供了技术思路，也为该项技术的工业放大提供了一定的基础数据。
