变浅

ABSTRACT It occurs that the performance of silicon bipolar transistors degradates seriously at low temperatures due to the gap-narrowing effect、the carrier freeze-out effect and the trapping effect of shallow dopants, which has significant influence on the operation of ultra-high-speed bipolar circuits and BiCMOS circuits at low temperatures.

硅双极晶体管由于禁带变窄效应，载流子冻析效应和浅能级杂质陷阱效应的作用，其电流增益和频率性能在低温下严重退化，从而极大地影响了低温高速双极电路和高性能的低温BiCMOS技术的发展。

Qiguzu reservoir in Kejiuliu blocks is shallow superheavy oil reservoir,it is exploited by steam stimulation primary,later,it is exploited by steam flooding,it is in later stage of steem flooding at present,effect of development turn to be worse.

克拉玛依油田九6区齐古组油藏为浅层特稠油油藏，初期采用蒸气吞吐开采，之后转为蒸气驱开采，目前处在蒸气驱后期阶段，开采效果变差。

Because of long mileage, every tire wears away and the tread pattern depth becomes very shallow.

If the sofa seat width is less than the former standard, sofa, space will become narrower; Seat depth too deep, can not be a natural droop calf, calf vulnerable to oppression; too shallow, a kind of impatient people will feeling; Seat is too high, just like sitting in high chair, very comfortable, if too low, people will feel when you stand up some more strenuous.

如果沙发座的前宽小于标准，沙发的空间就会变得狭窄；座面的深度过深，小腿无法自然下垂，腿肚容易受压迫；过浅，又会让人有种坐不住的感觉；座面太高，就像坐在高椅子上，很不舒服，如果太低，人站起来时就会感觉更费劲一些。

A wave becomes a shallow-water wave when the ratio between the water depth and its wave length gets very small.

当在水深度之间的比率和它的波长变得非常小时，一个波就成为一个浅水波。

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。
