可能的原因

Experts who believe that natural childbirth is beneficial to both the mother and child feel that anaesthetics may increase the possibility of complications during birth due to the fact that the woman may not be capable of pushing properly during the final stages of delivery.

专家谁相信，自然分娩是对双方都有利的母亲和儿童认为，麻醉剂可能会增加并发症的可能性，在出生，原因是该名女子可能不能够正确地推动在最后阶段的交付。

The results showed:(1)the factors which influence causal judgment were that the cause was the real cause or stimulative,the familiarity of the cause,and the covariation degree of causes with outcomes;(2)the character of questions didn't influence causal judgment;(3)causal judgment in some conditions were in accord with the probabilistic contrast model and the causal model theory,but they couldn't explain causal judgment in all conditions.

例如，在两个刺激同时出现并且之后伴随着一个结果事件出现的情况下，其中一个刺激对结果的作用可能被认为减弱了，另一个刺激被认为更易引起结果事件的产生[1]。多原因相互影响的现象，最初在动物条件反射中观察到，现在也已经在人类因果判断的实验中证实了[2]。研究因果判断中的多原因相互影响这一现象是有理论意义的，因为它证明了因果判断产生的情境重要性。

Look-Through Earnings Reported earnings are a poor measure of economic progress at Berkshire, in part because the numbers shown in the table presented earlier include only the dividends we receive from investees -- though these dividends typically represent only a small fraction of the earnings attributable to our ownership. Not that we mind this division of money, since on balance we regard the undistributed earnings of investees as more valuable to us than the portion paid out.

完整透视盈余我们认为帐列盈余很难表现伯克希尔实际的营运状况，部份原因在于列示在本公司帐上的股利收入，事实上仅占被投资公司收益的一小部份，其实我们并不要求盈余一定要分配，事实上对我们而言，我们更重视未分配的那一部份，因为他们极可能为我们创造出更高的价值，原因很简单，因为我们的被投资公司往往比母公司更有机会把资金投入到高投资报酬的用途之上，既然如此又何必一定要强迫他们把盈余分配回来呢？

Probably, the reason is that marriages between close relatives risk inbreeding depression (caused by individuals receiving two copies of broken genes from the same ancestor, but by different paths—one maternal and the other paternal). Outbreeding means this is unlikely to happen, and at least one functional copy of each gene will be received.

原因很可能在于近亲结婚存在近交劣势的风险（由于个人从同一祖先但是不同途径接受到了2份不完整的基因，父亲一份，母亲一份），远交意味着这种情况不太可能发生，子女至少能得到一份有功能的基因拷贝。

Just after he left school in 1958, he was arrested during a purge against "rightist" elements – possibly because his parents had once been landlords or possibly because of a friend who wanted to go to the US.

在尹明善刚刚离开学校的1958年，他在一场反"右派"运动中被捕，原因可能是他的父母曾经是地主，或者可能是他的一个朋友想去美国。

RESULTS Duodenal ulcer was the first cause of upper gastrointestinal hemorrhage. Gastric ulcer, cirrhosis, Mallory-Weiss syndrome or acute gastric mucous lesion was the second cause of the illness alternatively. The rate of endoscopy and emergent endoscopy has been going up year after year and got up to 80% in 1998. Bleeding and active hemorrhage, respectively were found in 24.3% and 14.9% of the patients underwent endoscopy before medication. Endoscopic hemostasis was performed in 108 patients by spraying hemostatics and a good response was achieved subsequently. Hemostatics were mainly cimetidine and yunnan baiyao before 1994. Reptilase, pPI, famotidine and ranitidine were used increasingly while cimetidine and yunnan baiyao were used decreasingly. Octreotide was used in patients with cirrhosis commonly. The length of hospital stay and the period from admission to bleeding cease tended to be shorter year by year, but the reduction rate was small. The uses of ranitidine, famotidine, pPI, reptilase, octreotide, early endoscopy and endoscopic therapy may play a role in improving the therapeutic effect of hemostasis, reducing the hospitalization and the mortality.

结果 十二指肠球部溃疡是历年上消化道出血的首要原因，胃溃疡、肝硬变、Mallory -Weiss综合征、急性胃粘膜病变则交替成为第2位出血原因；内镜诊断率和急诊内镜率逐年提高，1998年达到80%，内镜下见出血者占内镜检查的24.3%，而见到活动性出血者仅占内镜检查者的14.9%；内镜下止血108例次，成功率100%；1994年前治疗药物主要为云南白药和甲氰咪胍，之后，随着立止血、质子泵抑制剂、法莫替丁、雷尼替丁等药物使用的逐渐增多，前二者的使用逐渐减少，善得定多用于肝硬变出血；住院天数和止血天数呈逐年下降的趋势，但幅度微小；雷尼替丁、法莫替丁、PPI、立止血、善得定的使用以及及时的内镜检查和内镜下治疗在提高止血效果、缩短住院天数、降低死亡率方面可能起到了一定作用。

The expression of IGF-1 mRNA were breed different and sexual dimorphic, which was higher in Erhualian boars than in Large White boars, and higher in Erhualian boars than in gilts.

结果提示：猪脂肪组织中IGF-1的表达可能不依赖或部分依赖于GH，GH-R和IGF-1的品种差异可能是两品种猪脂肪沉积规律不同的主要原因之一。

Compare to other four syndromes,there is significant difference in Hp infection and histopathology.The main reason possible is that Fu Zhou and its peripheral region's specified weather and geographical environment There is a significant difference between light ,medium degree of splenogastric hygropyrexia syndrome and the other four syndromes.it is correlation to the severity degree of sinus ventriculi greater curvature's histopathology.

脾胃湿热证与其他四型相比在Hp感染、胃粘膜组织病理学上均存在显著性差异，分析其原因考虑福州地区特定的气候和地理环境可能是造成这一结果的主要原因；该证的轻、中、重不同程度在Hp感染上存在显著性差异，与胃窦大弯侧粘膜组织病理学的严重程度存在一定的相关性。

It can occur as the pain medication is wearing off before the next dose is due, or can emerge from a pain-producing activity or event.

其原因，可能是在下次止痛药使用之前，上次的药效已经消失；也可能是患者经历了一些会导致疼痛的活动或者事件。

For that nature is insufficient to account for the existence of either nature, since every nature is what it is by reason of its ultimate formal constituent. But it is precisely what—to the exclusion of all else—accounts for a thing's actual existence, that is the reason for its being necessary.

第二个矛盾是两者都把公共原因设定为其存在必然性的初始因，这不可能，因为这一原因对两者的存在来说都是不充分的，每一本性都是其最终形式要素决定的所是，排除所有其他，这就是某物真实存在的确切说明。
