无法研究的

Brain is a very complex non-linear system, and electroencephalograph and electrocorticogram are also non-stationary and nonlinear in nature, signal processing methods based on linear and stationary assumptions, although has obtained important result, can not grasp the entire picture of neuroscience.

人脑是一个高度复杂的非线性非平稳系统，所以脑电图和皮层脑电图也是非线性非平稳信号，基于线性和平稳假设的分析方法尽管取得了一些重要的研究成果，但是无法对神经系统进行更加深入的解释。

Studied the mechanism of interior loss factor of structral subsystems and accoustic subsystems. Studied the composing and methods of calculating interior loss factor of some normal subsystems like beams and plates. And analysised how to get the acoustic subsystem interior loss factor from sound absorption coefficient and air attenuation coefficient while no actural model of vehicle to test.

三、分析结构元件和声场内部损耗因子机理，研究将SEA方法应用到车辆系统时对于一些常见梁板子系统的内部损耗因子的构成和计算方法，以及在没有实际车型无法进行实测时，根据表面吸声系数和空气空间能量衰减常数进行理论计算声腔内损耗因子的方法，并利用SANTANA2000车型的实例进行实测对照。

Sometimes workouts are not effective at reducing stress because we use the time to think about all the stressful things we have going on, explains Larina Kase, Psy.D., president of Performance and Success Coaching and a psychologist at the Center for Treatment and Study of Anxiety at the University of Pennsylvania.

有时候身体活动无法有效降低压力，因为我们会用锻炼的时间思考那些带来压力的事物。 Larina Kase心理学博士解释道。 Larina Kase是表现和成功辅导公司的总裁，宾州州立大学焦虑治疗和研究中心的一位心理学家。

Objective To investigate association of genetic loci with CRP levels and risk of coronary heart disease.

据7月1日刊 JAMA 上发表的一项研究披露，一项对炎症生物标记C-反应蛋白的遗传变异与冠心病之间的分析无法对它们之间的因果关联给予支持。

Fisher sees the dangers of maladaptive love in fMRI studies she's conducting of people who have been rejected by a lover and can't shake the pain.

Fisher在用功能性磁共振成像对那些遭到情人的拒绝而无法摆脱痛苦的人们的研究中发现了适应不良爱情中的危险。

Although the Hough transform is widely used in image processing research, because it is a from the image space to parameter space of the mapping relations.

虽然Hough变换被广泛应用于图像处理的研究，但由于它是一种从图像空间到参数空间的映射关系，无法对无参数的离散的点进行提取。

Also, few centers perform pancreatectomy for nonmalignant disease because of problems with fragile diabetes, especially in alcoholics.

个人评论：单纯就其统计学意义来说，研究人员将接受手术的胰腺癌和慢性胰腺炎患者的死亡率进行了比较，统计表明手术治疗慢性胰腺炎手术死亡率低于胰腺癌患者，但这仍不能作为建议手术治疗慢性胰腺炎的依据，因为没有对慢性胰腺炎患者中手术治疗和非手术治疗患者的预后和死亡率进行对比，我们还无法认定手术治疗慢性胰腺炎效果优于非手术治疗。

The paper proposes a method which uses iteration learning control theory to design correction signal to self servo-writing loop. And the correction process can be used to conditions which precision model of plant can\'t be got. The convergence of iteration process can be proved by theory and experiments.

研究发现，自伺服刻写径向误差消除的过程很类似于迭代控制过程，提出用迭代学习控制算法设计自伺服刻写环路的校正信号，并从理论上证明该校正过程能够很好适应无法获取精确致动器模型的情况，证明了迭代过程的收敛性，实验证明径向误差得到较好抑制。

The concepts of dynamic transportation network were explained, and its characteristics were studied.

然而 ，传统的数学模型通常以独立的静态路网为研究对象，无法对动态演变中的路网进行有效的描述。

The concept that regards enterprise as economic body has been unconformable to nowadays intense market competition. Now regarding enterprise as a living body is becoming a rising orientation in management research area.

把企业视为经济体的传统管理观念已经无法适应激烈的市场竞争，而把企业视为生命体的企业仿生化研究，成为管理发展的一大发展方向。

I didn't watch TV last night, because it .
