Methods Spectrophotometry was used to study the activity of PLAP in the presence and absence of L Leu. PLAP relative activity was calculated according to the absorbance variation.

方法应用分光光度法分别测定有L－Leu和无L－Leu存在下的酶活力，根据其活力变化求出酶的相对活力；用双倒数作图法，确定L－Leu对PLAP的抑制类型并求出其抑制常数；同时也观察了pH对抑制作用的影响。

At last ,this pater prove that the Coxeter mat rix of A has a composition of the fundamental reflections with the condition that Q has no oriented cycles.

然后利用A 的Cartan 矩阵和对称双线性型定义了A 的基本反射，并利用数学归纳法证明了在Q 无有向圈的条件下， A 的Coxeter 矩阵可分解为基本反射的乘积。

After microinjection of the antagonists of glucocorticoid RU 38486 or mineralocorticoid spironolactone (40 ng/0.1 ul/site, respectively) into the rVLM bilaterally, a decrease in BP, HR and the pressor response induced by the dPAG stimulation was observed in the normotensive rat, and there was no change on the tachycardiac response induced by the dPAG stimulation.

分别微量注射糖、盐皮质激素的拮抗剂RU 38486(40ng/0.1μl/site)或螺旋内酯(40ng/0.1μl/site)至双侧rVLM，则引起正常血压大鼠的BP下降、HR减慢，以及电刺激dPAG诱发的防御性升压反应减弱，对电刺激dPAG诱发的加快心率反应无明显改变作用。

On the normotensive rat, bilateral microinjection of L-arginine (16 n mol/0.1 ul/site), a precursor of nitric oxide into the rVLM, caused a decrease in BP, HR and the pressor response induced by the dPAG stimulation, while microinjection of NG-methyl-Larginine (L-NMMA, 16 n mol/0.1 ul/site), a blockade for NO to form, into the rVLM bilaterally, caused an increase in BP, HR and the pressor response induced by the dPAG stimulation. There was no effect of both drugs mentioned above on the tachycardiac response induced by the dPAG stimulation.

五、在正常血压大鼠，于双侧rVLM微量注射一氧化氮前体(16nmol/0.1μl/site)可引起BP降低、HR减慢、以及电刺激dPAG诱发的防御性升压反应减弱；而于同区微量注射生成一氧化氮的拮抗剂N〓-甲基-L-精氨酸(16nmol/0.1μl/site)则可引起BP升高、HR加快、以及电刺激dPAG诱发的防御性升压反应增强；而上述两药对电刺激dPAG诱发的防御性加快心率反应均无明显作用。

Materials and Methods The triphasic dynamic enhanced CT findings of 52 patients with renal cell carcinoma were reviewed.

资料与方法回顾性分析52例肾癌患者的三期动态CT扫描资料，对经手术病理证实的透明细胞癌、乳头状癌、嫌色细胞癌3种肾癌亚型图像进行双盲法对比分析，比较肿瘤的大小、强化程度与模式（均匀、不均匀及主要周边强化）、有无钙化、出血、坏死与囊变、肿瘤扩散及淋巴结转移等情况，同时结合患者的性别和年龄，分析3种亚型肾癌之间的影像学差异。

It is shown that the ADFVLN, which has lower losses, high off-design performance and reliability, is superior to the vaned nozzle as the first stage and it also has more advantages than the early AFVLN, such as lower losses and less skewed boundary layer near the inner ring ect..

研究表明，这一新型轴流无叶喷嘴不仅具有原来同类喷嘴的优良性能，而且双出口结构和内环旋转的特点，使其流动效率明显提高，并省去两块隔板，缩短了机组的轴向尺寸，具有较高的工业应用价值。

Through measuring the gel time and the unconfined compression stre- ngth of cement-waterglass-clay specimen, this paper, using orthogonal method, analyzes the effect of different water-cement ratio, different admixing quantities of waterglass and different clay content on specimen strength and presents the optimal dispensation formula for two-fluid process of cement-waterglass.
