定向

In order to increase directivity and efficiency ,the optimum culture medium components were made certain according to breeding methods.

为了提高筛选的定向性和效率，根据育种思路确定了最佳培养基的配方。

So, the chief role for designing the directional coupler is to increase its directivity.

因此，提高方向性就成了定向耦合器设计的主要任务。

Simulation results show that this antenna can broaden the practical bandwidth for both higher directivity and impedance matching.

仿真结果显示这种改进增宽了此类天线兼顾高定向性和阻抗匹配的实用频带。

RESULTSdiabetic rats showed typical symptoms involving elevated serum glucose and weight loss (2)The rats in DM+VaD group reacted slower and made more error numbers in Y-maze than the rats in VaD group did, with a prolonged total reacting time in a whole day.(3)More neurons with serious damages, such as edema, ischemia or pyknosis could be found in DM+VaD group than in VaD group. More disarrangement of cone neurons, obvious glia proliferation, and more neuron apoptosis were found in CA area of hippocampus. CONCLUSIONS (1)2-VO in STZ-induced diabetic rats succeeded in establishing VaD animal models.(2) The cognitive dysfunction induced by VaD rats had been deteriorated by diabetes mellitus.(3)Morphology evidences proved that diabetes mellitus aggravated brain damages induced by VaD.PART II Effect of diabetes mellitus on the cholinergic nervous systemin CA1 area of hippocampus of VaDOBJECTIVE To estimate the role of cholinergic nervous system in hippocampus during the process of cognitive dysfunction aggravated by diabetes mellitus in DM+VaD group. METHODS Observe the changes of ChAT protein by immunohistochemistry stain. Chose three rats randomly from each group at each pointat two week, four week, and eight week, then sepa

经腹腔注射链脲佐菌素诱导慢性实验性糖尿病，1周后永久性结扎双侧颈总动脉(2-VO)制作VaD模型记录术后2周、4周和8周各组大鼠的体重及血糖；应用Y-迷宫检测空间定向学第二军医大学博士论文中…丈摘…要1ia；一色恤~﹁染澎糕行HE染色观察组织病理学孪叱；胶质细胞原纤维酸性蛋白protellZ，Cf冰尸标记观察星形胶质细舱的激活情况、橄声软公点娜育票票众糯黑橄居端粗默孺篇筑价井袱第二部分糖尿病对血管性痴呆大鼠海马c心区胆碱能神经系统的影响探讨海马CAI区胆碱能神经系统在糖尿病加重确D一大鼠认知障碍中所实验动物及分组同第一部分，应用免疫组织化学染色方法现察海马CAI{介狱牛第晕军l袭拔常博粗{论义

Pre-interventionresearches show that attribution to effort is positively effective for both winnerand loser,keeping individual's higher expectation of success and enforcingpersistent behavior during competition break.Whereas,positive effects ofattribution to ability and luck are limited.They have effects on expectation ofsuccess,which changes disparately to success and failure.

前干预研究表明：在直接的归因定向中，努力归因无论对成功者还是失败者都具有十分积极的效应，不仅能够促使个体保持较高的成功期望水平，而且可以增强竞赛间歇的坚持行为；而能力与运气归因则不然，它们的积极作用十分有限，仅仅表现在对成功期望的影响上，并将视成功还是失败发生迥然不同的变化。

Small aperture array ; wideband distortionless beamforming ; direction of arrival estimation ; multiple sources

小孔径基阵；宽带无失真波束形成；定向；多个声源

We disused the scores of explicit values factors into two parts.

内隐价值观的作用机制是积极定向的。

Power dividers and directional couplers are passive devices used in the field of radio technology.

功率分频器和定向耦合器是无源器件在外地使用的无线电技术。

It is shown through computation that the orientative exploring capacity of the tool is greatly enhanced because of the existence of the drill collar.

计算发现，钻铤的存在大大提高了仪器的定向探测性能。

First to unfold were the two 14-foot-wide drogue chutes,which criented the craft and continued slowing it.

首先要打开的是那两个 14 英尺宽的拖靶斜槽，这两个东西使飞机定向，并继续使之减速。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
