目的 建立惊厥阈下脑放电动物模型，研究惊厥阈下脑放电对大鼠空间变换学习记忆的影响。

The epilepsy model induced by kainic acid is a dynamical model condition. 5-7 days after acute seizure episodes induced by a single systemic injection of a convulsant dose (10mg/kg) of KA the rats developed a long-lasting increase in seizure susceptibility and the characteristic histopathological features in the hippocampus similar to human TLE. So the KA model has been a well-known model to study TLE or intractable epilepsy.

颞叶癫癎红藻氨酸（kainic acid，KA）模型具有明确的动态变化过程，一次全身性给予惊厥剂量（10mg/kg）KA诱发SD大鼠急性癫癎发作后5-7天，动物开始出现癫癎发作敏感性长期增强，脑内亦发生与人类颞叶癫癎相似的神经病理、神经生化及神经分子生物学方面的改变，因此被认为是研究颞叶癫癎和难治性癫癎的理想模型之一。

Objective To study the convulsive effects and mechanisms of tetramethylenedisulphotetramine.

目的 研究四次甲基二砜四胺对急性中毒动物的致惊作用及机制。

2005年11月16日和27日，运用稀释法和桡足类添加法，对厦门宝珠屿海域小型浮游动物及桡足类的摄食对浮游植物生长的影响进行了研究。

Hybrids of carbonate and terrigenous sediments Carbonate with terrigenous sediments are of characteristic from Emsian to Eifelian in stable shallow-sea faciesregion in Longmenshan area, and they can be classified evidently into hybrid Ⅰ and hybrid Ⅱ(Jingbaoshi-type). Type Ⅰ produced in mud shelf setting occupied hundreds of tempestite beds in which bottom cast、 hummocky cross bedding sandstones、 coquina were inter-beddded with shales that beared a great deal of verm traces、 bioturbations、 benthic communities dominative of brachiopods. Type Ⅱ in sand-mud-marl shelf was characterized by high-energy foreshore sandbeach facies and shelly bank facies.

碳酸盐与陆源碎屑混合沉积方面对微相、相特征、旋回样式、沉积机理研究表明，龙门山地区泥盆纪稳定浅海相区Emsian期和Eifelian期混合沉积十分发育，颇具特色，明显可以划分为两种类型：混积Ⅰ型，泥质陆棚背景下发育风暴沉积组构，幕式风暴期产生具丘状层理、底流冲刷构造的钙质砂岩、介壳岩，平息期则形成具大量虫管和生物扰动的深灰色、黄绿色页岩及海百合茎灰岩，腕足动物等大量繁盛；混积Ⅱ型，砂泥灰质陆棚背景下以发育高能前滨沙滩及生物介屑滩为特色，近滨至陆棚的砂泥灰互为混合，三者比例接近，肉眼难以区别确切岩石类型。

Corbicula fluminea, a bivalve commonly distributing in the tidal flats of the Yangtze River estuary, was selected for this study, which aimed to analyze accumulation characteristics of Zn,Cu,Pb,Cd and Cr in C. fluminea and to evaluate current situation of its biological quality.

以长江河口湿地生态系统一种习见的大型底栖动物河蚬Corbicula fluminea为研究对象，分析和评价了河蚬对Zn、Cu、Pb、Cd和Cr的积累特性以及长江口区河蚬的生物质量现状。

In conclusion, porcine cornea cannot be used as a model for human corneas in mechanical property studies.

因此，采用猪角膜作为人角膜力学研究的动物模型是不适合的。

The food safety of transgenic cottonseed and their effects on the antioxidant system of rat were examined.

本文研究了转基因棉籽的食用安全性以及对动物肌体抗氧化系统的影响。

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。

In pollen, from the model plant mouse-ear cress, a reduction in TUDOR-SN leads to fragmentation of DNA and premature cell death.

现在，一国际研究团队发现，植物和动物中决定细胞程序性死亡的遗传学过程实际上是进化相关的，并且用相同的方式执行功能。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
