The associated factors, clinical signs, treatment and prognosis were discussed. Result: Nine patients (6 female and 3 male) were included in this study. All of the patients were associated with myopia, ranging from -0.5 diopters to -5.0D. Gonioscopy revealed a dense homogeneous pigmented band seen over the entire circumference of the trabecular meshwork in all patients; however, no patients with iris transillumination defects were detected. Two of the patients developed pigmentary glaucoma and were treated with β-blocker, miotics and argon laser trabeculoplasty.

结果：九病例中有六位女性及三位男性，所有的病例皆有近视，分布於负零点五至负五点零屈光度，所有的病例在隅角镜检查皆可观察到浓厚的色素沈积在小梁组织，然而在这些病例并没有发现到有典型之虹膜透光缺损：其中有两例后来发展成色素性青光眼，以乙型阻断剂、缩瞳剂和氩氮雷射小梁整形术治疗后，病情控制稳定。

针对塔里木盆地石炭系盐层埋藏深，温度高，地层压力大，极易发生&缩径、坍塌&，造成卡钻，同时由于盐岩层的塑性蠕动，形成不规则井眼，甚至造成套管挤毁变形事故，井身质量难以控制，固井质量难以保证等问题，通过对同类型已钻井进行总结分析，提出了一系列钻井技术措施，并在T726井严格实施。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
