不尖的

The shock and heart failure caused by mitral regurgitation should be considered in patients with inferoposterior AMI after successful revascularization, who are still hemodynamically unstable.

当这类已接受成功血管再通后的下后壁心肌梗塞病人，其血行动力仍不稳定时，我们必须想到是二尖瓣膜逆流所引起的休克及心衰竭。

Stems twining; sepals rounded or obtuse apically, not mucronulate.

茎缠绕 顶部的萼片圆形的或钝，不具小短尖。

Results The clinical observation of 180 patients with entirely developed root apex of acute and chronic apical periodontitis shown that there was no significant difference comparing erythromycin ethylsuccinate-metronidazole-CP with FC in root canal sterilization, therefore, the irritability and poisonousness of the paste can be reduced by using erythromycin ethylsuccinate-metronidazole-CP instead of FC.

为了清除髓腔病源刺激物，促进根尖病变愈合，目前国内大多用甲醛甲酚进行根管消毒。甲醛甲酚属化学制剂，虽具有强烈的杀菌作用，但亦具有刺激性、毒性和抗原性等，而琥珀酸红霉素和甲硝唑在临床上已被证明对厌氧菌有明显疗效，对于根管内的消毒杀菌作用如何，研究报道不多。

It was shown that the root elongation was inhibited and the malonaldehyde content in root apices and the antioxidase activities of root apices were increased under Al stress (30 μmol/L), while the effects of Al were significantly alleviated by the addition of Si (1.4 mmol/L). Moreover, both Si added before Al treatment and Si added simultaneously with Al treatment could alleviate these effects. On the other hand, the cultivar of Seca was shown to be more sensitive to Al than other cultivars in the absent of Si, while Al-resistance distinction among the cultivars of stylosanthes turned to be non-significant in the present of Si in the pre-cultured solution or both pre-cultured and Al-treatment solutions.

研究结果表明，在铝(30 μmol/L)胁迫条件下柱花草根伸长受阻、根尖丙二醛含量和抗氧化酶活性显著增加，而硅(1.4 mmol/L)处理增加根中硅的含量而降低了铝对根伸长、MDA含量和抗氧化酶活性的影响，且铝处理前12h供给的硅和前处理溶液及铝溶液中均加硅处理的影响均显著；在不加硅条件下西卡品种的耐铝性显著低于其它品种，而经硅预处理的植株和在预处理及铝处理期间均供应硅的植株的耐铝性不同品种间的差异不显著。

Leaves 2–4 or more per ultimate branch; sheath subglabrous.

顶部的叶钝的或短尖，干燥时不棕红色。

Spikelets lanceolate to narrowly oblong, dorsally compressed; callus short, bearded, hairs usually less than 1/2 spikelet length; glumes cartilaginous to leathery; lower glume flat or slightly concave, hairy, back veinless or inconspicuously veined, flanks rounded in lower half, keeled toward apex, acute to truncate; upper glume boat-shaped, 1-keeled down midline; lower floret reduced to an empty hyaline lemma, rarely absent; upper lemma linear to oblong, occasionally broader, shortly 2-toothed or 2-lobed to middle, awned E.

小穗披针形的到狭长圆形，背压扁；胼胝体短，具髯毛，不到1/2的小穗长度的通常毛；颖片软骨质的到革质；更下部的颖片平或稍凹，有毛，背无脉或不明显，侧面圆形在下半部，龙骨状向先端，锐尖到截形；舟状的上面颖片，沿着midline龙骨状的1；更低的小花退化至一空的透明的外稃，很少无；上面外稃线形到长圆形，偶有宽，2齿或2裂的至中部，具芒的E。

Then he peered cautiously at Timmy, who promptly began to shriek. My father stepped back in alarm. Did he find it unsettling that this squalling stranger might be his own flesh and blood?

之后他小心谨慎地凝视着蒂米，蒂米马上吓得尖声啼哭父亲惊恐地倒退一步是不是想到这个哭哭啼啼的陌生的小家伙竟与自己骨肉相连，他觉得心烦意乱呢？

The Trojans advanced in a dense body, with Hector at their head pressing right on as a rock that comes thundering down the side of some mountain from whose brow the winter torrents have torn it; the foundations of the dull thing have been loosened by floods of rain, and as it bounds headlong on its way it sets the whole forest in an uproar; it swerves neither to right nor left till it reaches level ground, but then for all its fury it can go no further- even so easily did Hector for a while seem as though he would career through the tents and ships of the Achaeans till he had reached the sea in his murderous course; but the closely serried battalions stayed him when he reached them, for the sons of the Achaeans thrust at him with swords and spears pointed at both ends, and drove him from them so that he staggered and gave ground; thereon he shouted to the Trojans, Trojans, Lycians, and Dardanians, fighters in close combat, stand firm: the Achaeans have set themselves as a wall against me, but they will not check me for long; they will give ground before me if the mightiest of the gods, the thundering spouse of Juno, has indeed inspired my onset.

& 其时，特洛伊人队形密集，迎面扑来，赫克托耳领头先行，杀气腾腾，像石壁上崩下的一块滚动的巨岩，被泛涌着冬雨的大河从穴孔里冲下，凶猛的水浪击散了岩岸的抓力，无情的坠石狂蹦乱跳，把山下的森林震得呼呼作响，一路拼砸滚撞，势不可挡，一气冲到平原，方才阻止不动，尽管肆虐凶狂。就像这样，赫克托耳最初试图一路冲杀，扫过阿开亚人的营棚和海船，直插海边。然而，当接战对方人群密集的队伍，他的攻势受到强有力的止阻，被硬硬地顶了回来。阿开亚人的儿子们群起攻之，用劈剑和双刃的枪矛击打，把他抵挡回去，逼得他连连后退，步履踉跄。他放开嗓门，用尖亮的声音对着全军喊叫：&特洛伊人，鲁基亚人和达耳达尼亚人，近战杀敌的勇士们！和我站在一起！阿开亚人不能长时间地挡住我的进攻，虽然他们阵势密集，像一堵墙似地横阻在我的前头。我知道，他们会在我的投枪下败退，如果我真的受到神明的驱使，一位最了不起的尊神，赫拉抛甩炸雷的夫婿。

A drop ear is one which breaks at any point from its base to its tip or which is not carried stiffly erect but lies parallel to the top of the skull.
