半场线

The Lakers pushed their lead to 83-64 in the third because of a steal by Bryant and then because of his brashness.

科比在第三节的一次抢断帮助湖人以83-64领先，当时科比站在格林的传球路线上，并且成功把格林的传球拍到了对方半场，科比在左侧三分线前捞起皮球，瞄准篮筐稳稳把球投进。

In order to analyze and correct this effect, the method to calculate turn-off time is given. According to theoretical TEM response of multiturn loop source, TEM response affected by linear and half-sine turn-off current was calculated, and Taylor's series expansion was used by calculating TEM response of half-sine turn-off current. The two mode's responses, linear mode's response and half-sine mode's response, were analyzed in turn-off time 2μs-100μs.

为了分析和校正这种影响，文中给出了关断时间的计算方法，根据多匝回线源产生的瞬变场理论解析式，计算了线性和半正弦关断电流影响下瞬变场表达式，计算半正弦关断电流产生的瞬变场时将正弦函数进行泰勒展开；分析了关断时间在2 μs~100 μs之间两种关断模式产生的瞬变响应。

Under a fixed model of chromospheric flare, we investigate the influences of Hα and CaIIK line profilles on various velocity distributions from semiempirical view. The results show that: Hα line is very sensitive to the velocity in upper chromosphere; the profile of CaIIK line have responses to velocity in any layer of chromosphere, but the degree of CaIIK line asymmetry is much weaker than that of Hα and can be ignored if velocity is as small as 10km/s; chromospheric condensation in lower part of transition region have strong influence on Hα line but contrary to CaIIK line, the typical characteristic of H line effected by chromospheric condensation in transition region is reversed blue asymmetry, i.e. the intensity of blue peak is stronger than that of red peak; the stronger the chromosphoric condensation is, the more obvious the Hα line asymmetry appears; and so on.

在确定的大气模型下，从半经验角度系统地研究了大气各个层次的速度场和运动结构对Hα和CaⅡK谱线轮廓的影响，得到；Hα线对色球上部速度场敏感，而对色球下部和温度极小区附近速度场不敏感；CaⅡK对整个色球速度场均有反应，但不对称性较Hα弱，且速度小于10km/s时不对称性很不明显；CaⅡK受过渡区色球凝聚的影响较弱，而Hα对色球凝聚十分敏感；色球凝聚影响Hα轮廓的典型特征是呈反转结构的兰不对称性，即兰峰强于红峰；色球凝聚越强，Hα不对称性也越显著：等。

In dark-field condition, the results show that the defects have the characteristics of V C and its complex compounds, while the absorption spectra are obviously asymmetry and have wider ESR half-width.

结果发现，在暗场条件下获得的缺陷信息具有碳空位及其络合物的特征；谱线具有半高宽较大、峰谷明显不对称的特点。

The experiment was performed at the Asterix IV iodine laser with a prepulse 5 ns before the main pulse. Under optimum focusing conditions for main pulse and prepulse the X-ray laser beam splits into two beamlets along the target surface at its output end of the 2.5 cm long plasma column. The splitting was still observed when the prepulse alone was defocused.

实验发现在抽运激光主、预脉冲最佳聚焦条件下， X射线激光束在2.5 cm长的线状等离子体输出端沿靶面方向分裂成两束；在抽运预脉冲单独散焦条件下，仍然观察到这一分裂现象；但是当抽运主、预脉冲同时散焦时，这一分裂现象逐渐消失并获得了半宽度只有40 μm的非常窄的近场像。
