下界的

From the theory, the algorithm for determination of the degree of implicit polynomials is followed: detecting the stationary points in the object boundary based on its features, and then calculating the minimum degree according to the formula derived from the theorem. In addition, the theory can be extended to three-dimensional object.

Methods Eighty ASA physical status Ⅰand Ⅱpatients 18~65 years of age, scheduled for URL, were randomized into group CSEA(n=40) and group EA (n=40).Pinprick method was employed to determine anesthesia level, and local anesthetic dosage, onset time, time to attain optimal anesthesia level and anesthesia effect were recorded. Hypotension, shiver, postoperative headache and lumbodorsal pain were observed.

选择ASAⅠⅡ级、年龄18岁～65岁拟行尿道输尿管镜下碎石术的患者80例，随机分为腰麻—硬膜外联合麻醉和硬膜外麻醉两组；每组40例，采用针刺法测定麻醉平面，观察两组病例用药量、起效时间，上升到各个麻醉平面上界的时间及麻醉效果；术中患者出现低血压、寒战、术后头痛、腰背痛发生率。

The distribution characteristics of permafrost in this area were described based on drilling investigation. With the increase of altitude, the seasonally frozen ground zone is subrogated by patchy permafrost zone and then by continuous permafrost zone.

多年冻土分布具有明显的高度地带性，随高度增加，冻土分布呈现出季节冻土－岛状冻土－连续冻土更替，同时，多年冻土下界高程与经度明显相关，自西向东表现出下降趋势，下降率约为每经度150m，这一变化与降水在东西方向的变化有关。
