Simple things yeild no pleasure, but complicate things seldom yeild.

简单的事情不会有成就感，困难的事情却很难有成就感。

The invention discloses a disposing method of ammonia nitrogen waste water in the effluent disposal technological domain, which is characterized by the following: sieving heterotrophic nitrobacteria and aerobic denitrobacteria with stronger environment adaptive ability to nitrate and denitrate simultaneously; constructing mud nitrated and denitrated system to dispose waste water with nitrogen simultaneously to satisfy different DO densities.

为了解决同步硝化反硝化过程中菌种来源不明，调控困难，硝化和反硝化对DO浓度要求不同，在实际工程中难以实现同步硝化反硝化，本发明筛选出对环境有较强适应能力的异养硝化细菌和好氧反硝化细菌，采用异养硝化细菌和好氧反硝化细菌构建同步硝化反硝化污泥体系处理含氮废水，具有投资少，费用低，处理效果好，不仅去除废水中的氨氮，而且对总氮也有较高的去除率。

In past forty years, ongoing developments and advances have improved the reliability and predictability of dentinal adhesion.

Approximately 30,000 people per year in Taiwan, aged over 35, suffer a first stroke. 80% of stroke patients experience motor impairments, i.e., hemiparesis, poor coordination and gait disturbance. Abnormal spasticity is considered to be the major factor causing these motor impairments.

每年将近有三万多名三十五岁以上的国人发生第一次中风，80%的中风患者会有患侧肢体运动障碍如：偏瘫、动作不协调、步行困难等，而不正常痉挛现象是造成这些运动障碍的主要因素。

Cerebral blood pressure often seen in patients with low, onset is relatively slow, mainly manifested in hemiparesis, aphasia, sensory disturbance size, but also may have headache, dizziness, ringing in the ears, difficulty swallowing and speaking, sport and other non-conforming.

脑梗塞常出现于患者血压较低时，起病比较缓慢，主要表现有偏瘫、失语、半身感觉障碍，也可有头痛、眩晕、耳鸣、吞咽及说话困难、运动不协调等。

However, tracheal stent implantation is different from esophageal stent implantation. As patients with airway obstruction are always complicated by dyspnea and hypoxemia, even respiratory failure, which increases risk and difficulty of stent implantation. During tracheal stent implantation, the bronchofibroscope or stent entering the stenosis site may lead to complete tracheal obstruction-induced asphyxia. Corrosion of metal wire of stent to airway mucosa and vessels may result in hemorrhea, leading to postoperative hemoptysis. Stent dislocation is mainly caused by inappropriate selection of stent, inappropriate implantation position or severe cough. Carcinoma tissue growing along stent lumens can induce re-obstruction in stent, resulting in atelectasis relapse.

气管及食管支架置入均属有创性治疗，但气管支架置入不同于食管支架置入，气管阻塞患者均有不同程度的呼吸困难和低氧血症，甚至发生呼吸衰竭，加大了支架置入的风险和难度；气管支架置入者，当纤支镜或支架进入狭窄部位时可造成气管的完全阻塞引起窒息；支架金属丝对气管黏膜血管的侵蚀可引起大出血，导致术后咯血；支架移位主要由支架选择不当、置入不到位或剧烈咳嗽引起；癌组织沿支架网眼长入造成支架内再阻塞可引起肺不张复发。

When the Aoduya that be asked about by media most impressional accomplishs a design to be when, tom Chilton points out, there are a lot of achievements to be able to be reached between Aoduya, among them one is the Boss that defeats all Aoduya below difficult mode and final Boss, this will be very bad accomplishment.

当被媒体问到奥杜亚最有印象的成就设计为何时，Tom Chilton 指出，在奥杜亚当中有很多成就可以达成，其中一项就是在困难模式下打败所有奥杜亚的 Boss 与最终 Boss，这个将是非常难的成就。

Hangzhou Bay Bridge is the dream of many years Ningpo, Hangzhou Bay is the world's three-tidal bay, the biggest feature is a flood, streaming urgency, while the southern coast has a very wide beach, the beach there are more than nine kilometers, in the Land under some natural gas, the construction of a bridge in this place, in the past were very rare, and uniqueness lies in the special geographical environment, the difficulty of his decision, he is quite a high cost, so that the Hangzhou Bay Bridge The greatest feature is that under these conditions to build a bridge, how to overcome difficulties.

杭州湾跨海大桥是宁波人多年的梦想，杭州湾是世界三大强潮海湾，最大的特点就是一个潮大，流急，另外有一个南岸非常宽的滩涂，这个滩涂有九公里多，在滩涂底下还有一些天然气，在这个地方建桥，在以往是很少的，特殊性就是在于特殊的地理环境，决定了他的难度，他的成本也是相当的高，所以说杭州湾跨海大桥最大的特点就是在这种条件下要建设一座大桥，如何去克服困难。

Results The patients with complications (uroschesis, phlebothrombosis in the veins of lower extremity) and difficulty falling asleep of the survey group were significant fewer to the control group, and the p.01 by chi-squire test. All the wounds pain, lumbar and back pain, anxiety score and mean hospitalized days of survey group were less than the control group, above more, the satisfaction degree of patients of survey group was significant higher than the control one, and the p.01 by T test.

结果 观察组患者并发症、入睡困难者明显少于对照组，经χ2，检验p值均＜0.01，差异有显著性；观察组伤口疼痛、腰背疼痛、焦虑得分、平均住院日均少于对照组，观察组病人满意度明显高于对照组，经t检验p值均＜0.01，差异有显著性。

In the group (153 cases) resulted in positive results from both studies, there were angularis and antrum (including prepyloric and pyloric) lesions in 128 cases (83.66%). From the gastrocamera findings, there were 99 cases of gastric ulcers with 74 cases (74.75%) located at the angularis and antrum region.

在所统计的胃部疾病153例中有128例(83.66%)是位在胃角部和前庭区，所以大部分的毛病都是发生在胃的后半部，而在不相符合的诊断110例中，有87例（占79.09%）是因为胃炎的诊断分岐而造成，所以胃炎的诊断对X光来讲是比较困难的。

The split between the two groups can hardly be papered over.
