The ascending.reticular activating.sy.tem（ARAS）play. a key.role in the control of arousal and awareness for consciousness（Paus,2000;Zeman,2001;Van der Werf et al.,2002;Weiss et al.,2007;Siposan and Aliu,2014）.It is well known that the ARAS orig.nates from the reticular formation（RF）of the brainstem,and connects to the cerebral cortex via intralaminar to the cerebral cortex （Paus, 2000; Zeman, 2001; Van der Werf et al., 2002; y.o et al., 2013; jang and Kwon, 2015）. The hy.othalamus is involved in the reg.lation of sleep and awareness which is associated with the main timekeeper of consciousness （Lin, 2000; Lin et al., 2011）.

The present study.reported a 42-y.ar-old male patient who underwent conservative manag.ment for a spontaneous intracerebral hemorrhag. in the left corona radiata and the basal g.ng.ia. The patient presented with complete weakness of the rig.t upper and lower extremities at the onset of intracerebral hemorrhag.; however, he showed prog.essive motor recovery.to the level that he was able to extent the affected extremities ag.inst some resistance at 5 weeks after onset. The corticospinal tract of the affected （left） hemisphere connected to the left Broca＇s area at 3 weeks after onset as shown by.diffusion tensor tractog.aphy. By.contrast, this connection had disappeared at 5 weeks after onset as shown by.diffusion tensor tractog.phy. Transcranial mag.etic stimulation study.showed that no motor evoked potential was elicited from the affected （left） hemisphere at 3 weeks after onset, but motor evoked potentials were elicited at 5 weeks after onset. These finding. sug.est that the connection between the injured corticospinal tract and Broca＇s area in this patient appears to be a compensation for severe motor weakness; consequently. the connection seems to disappear with motor recovery.

根据汽车转向节热锻成形过程中的主要影响因素即坯料始锻温度、模具预热温度、上模运动速度和摩擦因数,运用DEFORM 3D软件对汽车转向节热锻成形过程进行了数值模拟,并应用正交实验法对数值模拟结果进行分析。结果表明:随着始锻温度的升高,转向节在热锻过程中的最大等效应力减小,能量和金属最大流动速度增大;随着上模预热温度增加,转向节热锻过程中的最大等效应力逐渐减小,能量和金属最大流动速度逐渐增大;随着上模运动速度增加,热锻转向节的最大等效应力先减小后增加,能量和金属最大流动速度呈现增大趋势;随着摩擦因数增大,转向节的最大等效应力和金属最大流动速度呈先减小后增大的趋势,能量逐渐增大,并通过比较极差值R判断了各个因素的主次关系。
