Aiming at the signal processing problems that exist in online fault diagnosis for train running gear, based on discussing the principle of characteristic spectrum analysis, a method of full period and uniform angle sampling is applied, which transfers the vibration signal from time domain into angular domain. The angular domain signal is transferred into corresponding characteristic spectrum using FFT. Through spectrum estimation and analysis, fault characteristic spectrum values of running gear components are acquired to distinguish their faults.

在讨论特征分析方法原理的基础上，针对机车走行部故障在线监测过程中存在的信号分析与处理问题，运用整周期等角度采样方法将时域振动信号转换为角域信号，采用FFT变换将角域信号变换为对应的特征频谱，通过谱估计、谱图分析得到机车走行部各零部件的故障特征谱值，再根据该特征谱值识别机车走行部各零部件的故障。

The short squeezes disappear and the player's pure strategies will be changed when the CS is added under the circumstances of which the informed trader or the insider tenders in the Treasury auction. Furthermore, under which SO is exerted after CS, any player's strategy is not changed when the market maker oversell in the WI. If the market maker buys long in the WI, and then, whether SO is exerted or not should be taken into consideration.

在信息灵通交易商或内幕交易商参与投标的国债市场里，实施"基本承销额"制度消除了他们对市商的"逼空"机会，也改变了局中人的纯策略选择；当市商在预发行交易中卖空时，行使"追加选择权"不改变局中人纯策略选择，对于市商而言，应该行使"追加选择权"当市商在预发行交易中买空时，则应谨慎考虑。

objective to investigate the paregoric effects of butorphanol when the errhysis occurs inside the epidural catheter during continuous epidural anesthesia.methods 60 cases of kidney stones received elective surgery.during this surgery they underwent continuous epidural anesthesia and eight cases of them showed the errhysis in the epidural catheter.then epidural injection of butorphanol was given for analgesia and hr,map,spo2 as well as muscle relaxation conditions were monitored before and 5,10,20 min after injection.the conscious and breathing of patients were also monitored.results before and 5,10,20 min after injection of butorphanol,hr and map difference were not statistically significant.the analgesic results were satisfactory.conclusion butorphanol has a definite analgesic effect when the errhysis occurs in epidural catheter during continuous epidural anesthesia.

Antegrade urography via percutaneous needle or tube nephrostomy is of particular value when the obstructed kidney fails to excrete the radiopaque material on excretory urography. This procedure allows application of the Whitaker test, during which fluid is introduced into the renal pelvis at varying rates.

顺行时尿路造影：当阻塞的肾脏在排泄性尿路中造影剂不能排泄时，使用经皮针或者说导管行肾造瘘特别有价值，这种操作可施行Whitaker试验，在试验期间液体可以不同程度注入肾盂。

The matrix =( xi, xjp having the e-th power of the greatest common P-divisorp of xi and xj as its-entry is called the e-th power GCD matrix on S. The matrix = having the e-th power of the least common P-multiple p of xi and xj as its-entry is called the e-th power LCM matrix on 5. We obtained the following results:(1) is nonsingular for any set S;(2) If S is an FC set, then the determined of has formula Det =Jpe(x1)...Jpe, where the function Jpe is the generalized Jordan totient function;(3) A formula of the inverse of is given when S is an FC set;(4) If S is an FC set, then |.

Home ranges of the sables were 4. 2—17. 2km〓. Males have larger home range size than femals. Home ranges sizes were different in every season. Home ranges were the Largeat in winter and smallest in summer. There was overlap between the males and the females and the two males seldom orlapped. Actiltty during the snow-free season was strongly diurnal wheareas winter activity was largely nocturnal. Activity was stronger at 6—8. 18—20 and 20—22. Sable's activies and food diversity index wes strongly corrected.

1995年4月～1996年11月。在内蒙古满归林业局北岸林场采用无线电跟踪技术和全球定位系统研究了紫貂的巢区和生境选择，紫貂巢区大小为4.2～17.2 km〓，雄性个体的巢区大于雌性个体的巢区，四季活动范围有差异，冬季活动范围最大而夏季最小，巢区的重迭多发生于异性个体，而雄性个体的巢区几乎不重叠，而且巢区呈线性趋势，紫貂在冬季主要是夜行，而其他季节主要是昼行，一般6～8时和20～22时活动较强，而且其活动率与其食物多样性指数成正相关。
