间变

The simulations of this algorithm are enumerated in following instances: track of saw-tooth wave, fundamental and total harmonic analysis, inter-harmonic detection, peak detection, and detection of flicker of voltage.

通过仿真，用该算法实现锯齿波跟随、基波提取和谐波分析、间谐波分析、电压峰值检测、电压闪变检测，并研究算法对输入信号频率偏移的鲁棒性。

The 4th left rib was cut and a model of left coronary artery occlusion/release was carried outo Rats were divided randomly into 4 groups: control group without LCA occlusion (group A, n=6);I/R group(group B, n=6); ketamine(5mg.kg-1)+I/R group (group C, n=6); ketamine(10mg.kg-1)+I/R group(group D,n=6)o All rats in groups B, C , D were subjected to 30 minutes of LCA occlusion followed by 120minutes of reperfusion. Rats in group C and D were injected with 5mg.kg-1 and 10mg.kg-1 of ketamine before reperfusion, respectively. Significant electrocardiogram and color changes at the area at risk were considered indicative of successful coronary occlusion and reperfusionc Serum was exampled from left jugular vein at 30 minutes and 120 minutes during reperfusion to measure IL-6 and TNF- level by ELISA measurements. After reperfusion of 120 minutes, the heart was removed and the cardiac apex was exampled with snap-frozen in liquid nitrogen and stored at -70 C .

采用左冠状动脉前降支结扎开放建立心肌缺血／再灌注模型，健康SD大鼠24只，随机分为心包打开假手术组(A组，n=6)，缺血／再灌注对照组(B组，n=6)，5 mg·kg~(-1)氯胺酮+缺血／再灌注组C组，n=6，缺血30min后右腹股静脉注入5 mg·kg~(-1氯胺酮，10mg·kg~(-1)KTM+I／R组D组，n=6，缺血30min后右腹股静脉注入10 mg·kg~(-1氯胺酮。10％水合氯醛40 mg·kg~(-1)腹腔注射麻醉，气管切开，连接多功能监护仪记录心电图；小动物呼吸机人工呼吸，呼吸频率60次／分，潮气量2ml／100g，于左胸第四肋间打开胸腔暴露心脏，在左心耳下1mm左冠状动脉处，用丝线，眼科外用不锈钢小圆针穿过心肌浅层，稳定10min后将U型含有铜丝的胶管置于冠状动脉表面一起结扎(A组不结扎，B、C、D组结扎)；结扎开始左心室心尖部即由红色变暗，30 min后呈暗红色，心电图中出现S-T段抬高，说明缺血形成。

Although the winter, but there is no winter should have what kind of bone-chilling wind, and some sprinkle it clear moonlight shines on the earth, let the winter nights become transparent in general, so that a more broad in between heaven and earth.

虽然是冬天，但还没有冬天应该有的那一种刺骨的寒风，有的是那清澈的月光撒照在大地上，让冬天的夜变得透明了一般，使天地间更加的宽阔了。

In other words, you can make the thunderstorms more frequent and you can make them much heavier.

也就是说，你可以使雷暴变得更频繁和更严重，短时间产生大量云水。

Responses to the selection pressures incurred by the novel abiotic and biotic factors in introduced ranges are primary causes for alien species evolution, although other factors such as intra- and inter-specific hybridizations, genetic shifts can also cause evolution.

种内或种间杂交、遗传漂变、新环境带来的新的选择压力等是促使外来种发生进化的重要原因。在入侵地，响应来自非生物和生物因素的选择压力是外来种发生适应进化的主要原因。

They are distractions at recess, in terms of kids wanting to play with them, which leads to altercations,said Peter Bonaccorsi, principal of Milford elementary school.

另一所小学的校长彼得·伯纳科尔西说：&那些游戏机会让孩子们在课间休息时变得心烦意乱，由于很多学生在同一时间内都想在它们身上一试身手，这很可能会导致相互间的激烈争吵。&

Through the change of roles, the children will experience different roles and become more familiarised with the physical and social environments of a clinic or a hospital.

通过改变角色，孩子们将经历不同的角色，变得更加熟悉的物质条件和社会环境的一间诊所或医院。

Semi-facticity simulation can avoid modeling of complex non-linear time conversion system in pilotless aircraft system, test functions and capabilities of equipment, and assess coherence during equipments.
