Yttrium isopropoxide was prepared directly by the reaction between yttrium and isopropyl alcohol using mercuric chloride and iodine as catalyst. Yield is above 83% . This method possesses the merits of easy operational approach, high product purity, high reaction rate and high production rate. Compared with the previous reported results , the period needed was shortened by 19 h and the yieid increased by 8% . The period needed for preparation is about 5 hows. These results are better than the present report . The dehydrolysis method of isopropyl alcohol and the composition of catalyst were presented.

Objective To evaluate magnetic resonance imaging （MRI） characteristics and surgical results of adrenocorticotropin （ACTH） -secreting pituitary adenomas. Methods MRI characteristics and relationship between MRI positive rate and surgical results of 266 patients with pathologically confn＇med Cushing＇s disease were analyzed retrospectively. All patients underwent thin-section sagittal and coronal scans of the pituitary gland before and after administration of gadolinium-diethylene triamine pentaacetic acid （Gd-DTPA） on a 1. 5 Tesla MR/scanner, and dynamic enhanced MR/was performed in 39 patients. All patients underwent transsphenoidal adenomectomy. Endocrinological examinations and assessments were performed. Results Preoperative MR/revealed normal results in 41 （ 15.4% ） cases, microadenoma in 179 （67. 3% ）, macroadenoma in 42 （ 15.8% ）, and huge adenoma in 4 （ 1.5% ）. Pituitary apoplexy was found in 13 （4.9%） cases. Positive rate of ACTH-secreting adenomas was 84.6% （225/266） on MR/scans, and that of small microadenomas was 87.2% （34/39） on dynamic enhanced MRI scans. Preoperative endocrinological tests of 199 cases supported the diagnosis of typical Cushing＇s disease, while the other 67 cases had atypical endocrinological results. The endocrinological cure rate, remission rate, and inefficacy rate were 85.7%, 7.9%, and 6. 4%, respectively. There was no difference in the initial endocrinological cure rate between the patients with positive and normal MRI results （90% vs. 87. 8%, P =0. 904）. Conclusions Enhanced coronal pituitary MR/ is helpful for preoperative localization of ACTH-secreting pituitary microadenoma. Dynamic enhanced MR/may improve detection rate of microadenoma. There is no marked difference in the surgical results for patients with preoperative MR/results indicating presence or absence of microadenoma.

记L^(2)为单位圆周T上的Lebesgue平方可积函数全体.定义Hardy空间H^(2)是L^(2)中的解析多项式所张成的闭子空间.对于复平面中的单位开圆盘D中的任一点z,函数K_(z)(w)=1/(1-zw)是H^(2)中的再生核函数.对任意的f∈H^(2),众所周知T_(f)K_(z)=f(_(z))K_(z),即K_(z)是T_(f)的属于特征值f(z)的特征向量.反过来,若存在z∈D(或对每一个z∈D),使得K_(z)是T_(f)的特征向量,是否必有f∈H∞针对这些问题,本文给出了以再生核K_(z)为特征向量的Toeplitz算子以及有界线性算子的完全刻画,还给出了以所有的f(z)(z∈D)为特征值的Toeplitz算子的部分刻画.

带宽利用率是网络传输能力评价的核心指标,其值过高节点会出现拥塞现象,导致网络性能急剧下降。为此,基于该指标提出一种指数函数调制的路由算法EBURM。构建一个目标函数模型,给出目标函数中传输效率、带宽利用率和步长因子的理论值和计算公式,并在当前主流园区网架构基础上,利用仿真工具对OSPF经典路由机制和EBURM路由机制进行验证比较。实验结果表明,EBURM在控制路径条数目为5以内的条件下,具有优良的线性特征,可最大限度调节网络中源节点的流量发送策略,降低流量传输的代价。
