The anode structure of CI-LIGBT is optimized by numerical simulation, and it is pointed out that segmented p〓 anode region surrounded by n〓 anode region is the key to improve the ability of current limiting, and the more deeper the n〓 anode junction relative to the p〓 anode junction, the more powerful the ability of current limiting is. The affection of the breakdown voltage BV〓 of the reverse biased p〓n〓 junction and the sample resistance upon the latching current, the latching voltage and the on-state voltage have been studied, and it is indicated that the tradeoff between the on-state voltage and the latching characteristics is the excellentest when BV〓 is 1. 1V so that its on-state voltage can be just only 0.6V higher than conventional LIGBT. It is also found that this device is especially suit to high temperature environment. Based on X. B. Chen's surface voltage sustaining structure using optimized variational lateral doping and Ludikhuize's multiple floating rings structure, high voltage LIGBT and is studied in this paper.

通过数值模拟，优化了CI-LIGBT的阳极区结构，指出采用被n〓阳极区包围的单元状p〓阳极区是提高该器件限流能力的关键，而n〓阳极区结深相对p〓阳极区结深越大，器件的限流能力越强；分析了反偏p〓n〓结击穿电压BV〓和取样电阻对器件闩锁电压、闩锁电流和导通压降的影响，得出BV〓在1.1V时器件导通压降和抗闩锁能力间的折衷关系最优，其导通压降仅比普通LIGBT高0.6V；分析了温度对LIGBT闩锁性能的影响，表明CI-LIGBT即使在450K的高温下也不会闩锁，尤其适用于高温工作环境。

The accuracy of predictive saccade had correlation with MoCA score (correlation coefficient was 0.485, P=0.016), while had no correlation with scores in motor portion of UPDRS and Hoehn-Yahr stage (correlation coefficients were 0.087 and 0.007, P=0.686 and P=0.974, respectively).

In general, if one possesses evidence that one normally would take to support ~p and yet believes p instead due to some desire, emotion or other motivation one has related to p, then one is self-deceived.

总体来说，如果一个人拥有了正常的时候会拿来支持-p的证据，而却因为某种欲望、情绪或别的拿来与p关联的动力，去支持p，那么这个人就被自我欺骗了。

It was suggested that aging did not only influence diastolic filling period, but also influence STI. 3. With increasing age, whether at rest or during exercice, fractional shortening of minor semiaxis, mean velocity of circumferential fiber shortening, cardiac index and ejection fraction did not change, but immediately post pacing, PEP prolonged and PEP/ LVET increased in elderly group and did not change in young group. It was suggested that STI was sensitivity in detecting systolic function of LV. 4. There was a good correlation between aging and decreased compliance and diastolic function of left ventricle which was manifested by a reduction of early diastolic peak folw velocity, time-velocity integral of early diastole, 1/3 filling fraction (1/3FF)(r=-0.958,-0.875 and -0.937, P＜0.01～0.001) and a significant compansatory increase in peak flow velocity of atrial contraction, time-velocity integral of atrial contraction, the ratio between APFV and EPFV and the ratio of ATVI and Total TVI (r=0.958, 0.956, 0.966 and 0.986, P＜0.001) and the prolongation of Dec T and RFP with increasing age. It was particularly true for the subgroups above the age of 50 years.

静息状态下收缩时间间期与年龄无相关性，负荷后即刻，老年组射血前期延长(P＜0.05)，射血前期与射血期比值加大(P＜0.05)，青年组无变化，提示年龄因素亦影响STI，但由于静息状态下得到代偿，STI变化往往表现不明显。3、静息及负荷状态左室短轴缩短率、平均周径缩短率、心指数及射血分数均不随年龄增长而变化，而负荷后即刻老年组PEF延长，PEP/LVET加大，提示STI是检测左室收缩功能的敏感指标。4、随年龄增长，心房收缩期充盈峰值流速、流速积分、充盈分数及心房收缩期与舒张早期充盈峰值流速之比值显著增高(r＝0.958、0.956、0.986及0.966，P均＜0.001)，舒张早期充盈峰值流速及流速积分、1/3充盈分数(1/3FF)下降(r＝-0.958、-0.875及-0.937，P＜0.01～0.001)。
