极严重的

First, the speed of the reaction between mud acid and rock is very fast, the effective distance of acid is short, active acid can not reach deep formation.

首先，高温下常规土酸与地层矿物反应速度极快，酸液有效作用距离短，活性酸不能到达地层深部；其次，HF与铝硅酸盐的化学反应不是简单的一次反应，其副产物氟硅酸和氟铝化物还可与铝硅酸盐发生二次反应和三次反应，形成一系列不溶性的沉淀物，对储层造成严重伤害；第三，高温情况下酸液对井下管柱及工具腐蚀性很强，对缓蚀剂性能要求高。

Shape selection of high-pressure direct atomize nozzle is carried, and then the nozzle's inner structure parameters' influence to its inner flow status and outlet atomization characteristics is simulated and tested. After such primary experiments, further modification of nozzle is taken.

细水雾来火技术具有无环境污染、灭火迅速高效、耗水量低、水渍损失极小、灭火效果良好等特点，是了连云港消防界在"蒙特利尔协议"签定后，规定在二十一世纪初叶要求取缔的对大气臭氧层有严重破坏作用的哈龙灭火系统的在效替代灭火系统。

For example, the coefficient of variation of Cd is as high as 212%, reaching the level of serious pollution.

结果表明：AS、Cd、Cr、Pb、Zn显示了很强的富集且分布极不均匀，如Cd的变异系数高达212%，且已达到了严重污染的程度。

The result also showed that return treatment is better than taken treatment within different treatments. 4. According to the experiment when the plant was harvested(In March 25th,2009), it was found that the rape with NPK treatment,especially with NPK-T treatment in Quaternary red soil and in granitization red soil, grew abnormality or dead in the centre of district(80%),which yield was extremely low,but had some to the remaining(20%) close to the cement ridge.Among the three types of parent material,eighteen districts,Dischaemum Schreb of gramineae plants could only grow in granitization red soil with NPK treatment,and the other sixteen districts were little or even not.The rape planted in Quaternary red soil with NPK treatment got disease especially in the centre of the district.

其次是M处理，CK最低。3、三种母质种植油菜均表现为：归还处理好于带走处理；4、据试验收产时（2009年3月25日）发现：四纪红土和花岗岩二种母质的NPK处理的油菜除靠近水泥梗边行长有部分油菜外（占小区面积20%），小区中间（占小区面积80%）的油菜生长不正常或死亡，产量极低；三种母质共18个小区，只有花岗岩母质的NPK处理长有禾本科植物马唐草，其余16个小区很少或没有；四纪红土NPK处理油菜病害严重。

Using the normal planar technology of bipolar junction transistor,we have fabricated the p n p high frequency,high breakdown voltage transistors which can operate in the wider temperature range from -55℃ to 180℃.

一、引言新器件的设计基于以下三方面的考虑：（1）众所周知，常规双极结型晶体管的hFE随温度上升而增大，具有正的温度系数，特别在较高温度更为严重。

November 2001, the vitta below the well ruptures, the pressure below the well appears unusual, this year in January, flat aggravate -- if do not take strong step, cause malign accident extremely likely, destroy Chuanxide finally the big gas field with area the richest gas pool, make people life property is damaged badly.

四川德阳市境内中国石化控股的新场气田中的新851井，是2000年10月投产，日产天然气40万立方米的高产气井。2001年11月，井下油管断裂，井下压力出现异常，今年1月，漏气加剧——若不采取有力措施，极有可能造成恶性事故，最终破坏川西地区气藏最丰富的大气田，使人民生命财产受到严重损害。

Jensen's group randomized 32 high-risk patients with severe ulcer hemorrhage and nonbleeding adherent clots resistant to target irrigation to medical therapy or to combination endoscopic therapy, which included epinephrine injection, shaving down the clot with cold guillotining, and bipolar coagulation on the underlying stigmata.

受试者包括32名严重溃疡出血的患者，目标灌洗对溃疡面上的无出血粘著血凝块无效，他们的再出血危险率很高。Jensen小组将这些患者进行了随机分组，其中一组接受药物治疗，另一组联合内视镜治疗。联合内视镜治疗包括注射肾上腺素，用冷切刀削去血凝块，以及将双极凝结剂涂抹于潜在出血处。

The failure detected by UBM may be due to:①severe choroidal detachment;②posterior segment RD;③a narrow palpebral fissure that hampered enough exposure to examine the ora serrata and the part of the eye ball posterior to it.

不能发现视网膜脱离的原因有：①严重脉络膜脱离；②后极部视网膜脱离；③睑裂过小，难于暴露到眼球的锯齿缘及其后方的部分。

But Florida Solicitor General Scott Makar says the life without parole sentence is used sparingly."We'd like to think that it is only used rarely, in those cases that are justified for public safety purposes where we have serious violent offenders."

但是佛罗里达州的副检察长Scott Makar说平常很少采用无保释终身监禁这样的判决，&我们认为这种处罚极少用，只有在考虑到公众安全，对那些严重暴力份子才会采用这种处罚&。

I'm strongly against the death penalty — it's an eye for an eye.

我不赞成死刑——这是以牙还牙的报复行为。

And to get you the support you need, we're enlisting all elements of our national power: our diplomacy and development, our economic might and our moral suasion, so that you and the rest of our military do not bear the burden of our security alone.

并给你们所须的支援，我们正徵召国家所有各种的力量：我们的外交及发展，我们的经济力量与道德劝说，所以你们与其他军人不须要孤独地负起国家安全的责任。
