Prolapsus will produce high pressure to the lower apparatus in the belly cavity ,such as uterus ,ovary, bladder and sigmoid colon .the patient complains the there is oppress on the bladder ,and pain in the crura and the groin .the pressure on the ovary and uterus is one of the reasons of un-pregnant 自主神经环（autonomic nerve wreath

横结肠下墬对腹腔低部器官，如卵巢、子宫、膀胱及乙状结肠产生极大的压力，病人会抱怨膀胱有压迫感，下肢及腹股沟疼痛。因数宫及卵巢的压迫，也是产生不孕症的原因之一 2。

The rain-water pumping station is one of the most important parts of city flooding preventing system.

摘要 雨水抽水站是都市防洪最重要的一环，若能更安全及有效率的运转，对市区防汛安全将有莫大的助益。

So it may be extremely significant that using the simple effective Heck reaction to synthesis the complex compounds containing the pyrrole or the pyrrolidinone ring.

因此，利用简单高效的Heck反应合成含吡咯或吡咯酮环的复杂化合物将是非常有意义的工作。

It was proved that the proposed adaptive fuzzy fault tolerant control approach guaranteeing all the closed-loop signals were semi-globally and uniformly bounded, and the tracking errors converge to a small residual set around the origin.

证明了所提出的自适应模糊容错控制方法能够保证闭环系统所有信号是半全局一致有界的，且跟踪误差收敛到原点的一个小邻域内。

Washing, cutting ring and eyes require board (disc valve pump valve is the plate with the tie bar and wear-resistant film from top to bottom) the gap is smaller, there is a large amount of water to be strictly sealed, so to clean the ball forward after the infiltration of water .

水洗，要求切割环和眼睛板(碟阀泵则是板阀与系杆和上下耐磨片)的间隙要小，需有大量的水，严格密封，做到清洗球后的水不向前渗透。

The Giant Leopard Moth or Eyed Tiger Moth has a distinct pattern of black rings, reminiscent to those found in its namesake the leopard.

We can see that bicyclic, tricyclic, tetracyclic rings or even outside the bustling construction sites everywhere, but ordinary people can afford the number, which those in the industry or buyers have to have sufficient alertness.

我们可以看到，二环，三环，四环，甚至内外环繁华的建筑地盘无处不在，但普通民众可以负担的数目，这是该行业或买家必须有足够的警觉。

The degradation of PAHs at 0.03, 0.3, and 3 mg/g soil, either added singly or as mixtures, were evaluated for their evolved CO2 in Biometer flasks. The contaminated soil was later Soxhlet extracted with hexane. The extracts were evaporated, redissolved in dimethyl sulfoxide, and subjected for Microtox assay and Medaka embryo toxicity test. The evolved CO2 from singly PAHs addition was correlated with concentration gradient.

根据结果显示，受单一PAHs污染土壤之降解量，以CO2累积量表示，两环之Naphthalene其降解量为最多，在低浓度0.03 mg PAHs/g soil时，有所谓的诱引作用产生；受混合PAHs污染土壤之降解量，以Naphthalene对於Phenanthrene的刺激作用为最大；在复育实验方面，以添加苯酸之CO2累积量为最高，单就界面活性剂而言，则以Tween 80的表现为最佳。

It is almost the most important circumstance in life, since nothing is more corroding as frequently to meet persons with whom one has any difference.

这几乎是生活中最重要的一环，因为没有什么比经常要遇到心有龃龉的人更令人沮丧的了。
