没有变化的

Both IS and NA increased heart rate, while propranolol (Pro, 25#mu#g per min) produced a decrease. Phentolamine (Phen, 25#mu#gper min) had no effect. All these effects were similar in vagotomized as well as in unoperated rats. It was shown that the reversal of the effect of sympathetic nervous system on gastric acid secretion is not due to changes in circulation.

IS和NA增加大鼠心率，心得安(25μg/min)显著地减少它，而酚妥拉明(25ug/min)没有明显的作用；IS， NA、心得安或酚妥拉明对迷走神经完整、VT即刻和三月后的大鼠心率的影响均无差异，表明VT后交感神经系统调节胃酸分泌的作用吃变化并非循环改变的结果。

The sight of his sharply focused and unchanging eyes unnerved me, and I was quiet inside and full Of love for those nearest me-my human children, my dark-haired little Benji and my tender willowy Sybell--but I was not strong enough just yet to take them away.

他那双直直注视，毫无变化的眼睛让我不安，可我的心中很静，充满了对与我最亲近的人的爱--我的人类儿女，我黑发的小本吉和我温柔纤秀的丝贝尔--但是我此时还没有意志带他们离开。

With the market competition turning worse and the custom requirement being of diversity, presenting enterprise information system must be capable of adapting all variances. If the enterprise information system has no good flexibleness and could not customize, or second-hand develop, it will become the fetters of enterprise development.

随着市场竞争的加剧和客户需求的多样化，现在的企业信息系统必须具有适应各种变化的能力，如果企业信息系统没有良好的柔性，不能方便地进行用户化和二次开发，那么这样的信息系统反而会成为束缚企业发展的枷锁。

The comparative studies of lithogeochemistry for the volcano-intrusive complexes both from Jiulongzhang and from xiangshan reveal that the chemical compositions of the volcano intrusive complexes in the two areas are very close, and the trace element spidergrams and REE patterns basically coincide with each other. It is also shown that the two volcano-intrusive complexes have the same source features and the active continental margin tectonic settings. At the same time, it is found that, from early volcanic magma activities to later intrusive magma activities, the content of SiO2 and the Rb/Sr ratio decreased, on the contrary, the content of MgO and the ratios of K/Rb, Ba/Rb and LREE/HREE increased. It is shown that the hypabyssal or ultra-hypabyssal intrusives are not the products of the volcanic magmatic differentiation.

两地区的火山－侵入杂岩的岩石化学成分及其变化特点极为相近，微量元素蛛网图和稀土配分型式也基本一致，它们具有相似的岩浆过程和统一的活动陆缘构造背景；同时，从早期火山岩浆活动到晚期浅成－超浅成岩浆侵入活动，其w(SiO2)和w/w的值降低，而w以及w/w、w/w和w/w的值增高，晚期浅成－超浅成侵入岩与早期火山岩没有直接的分异演化关系。

The object change will immit some fresh blood in the research field. Because region in a country is an open system, especially for finance, market is highly integrated, and fund and other factor freely flow.

这一研究对象的变化显然会为该领域的研究注入新的血液，因为一个国内的地区相对于其他地区是完全开放的，尤其是对于金融这一要素而言，市场是高度统一的，资金的跨地区流动也没有制度的限制。

First major extinction (c. 440 mya): Climate change (relatively severe and sudden global cooling) seems to have been at work at the first of these-the end -Ordovician mass extinction that caused such pronounced change in marine life (little or no life existed on land at that time). 25% of families lost (a family may consist of a few to thousands of species).

第一次大量物种灭绝（c.440 mya）：较为严重的突然全球变冷似乎先发生，然后就有了引起海洋物种显著变化的后奥陶纪的大量物种灭绝（当时很少或者根本没有生物在大路上生存），大约25%的物种科目消失了（一个物种科目可能含有几十到上千的物种）。

Romani culture is diverse and there is no universal culture per se, but there are attributes common to all Roma: loyalty to family; belief in Del and beng; belief in predestiny; Romaniya, standards and norms, varying in degree from tribe to tribe; and adaptability to changing conditions.

吉普赛文化十分多样，没有统一的文化形态。但是对于所有吉普赛人而言，他们共同的特点是忠于家庭，信仰鬼神，相信命运注定；吉普赛的标准规范随部落的不同而又一定程度的差异；此外对变化的良好适应性也是他们共同的特点。

Low-molecular-weight EC was attained with ethylcellulose being degraded by 34% nitric acid; Fourier transform infrared spectroscopy, 13C-NMR,element analysis confirmed that the basic structure and major properties of low-molecular-weight EC maintained agreement with those of undegraded EC except that the polymerization degree of EC decreased.

乙基纤维素被 34%硝酸降解可以得到低分子量的乙基纤维素；FTIR，1 3C- NMR，元素分析，X-射线衍射分析证实在硝酸降解过程中，除了聚合度和结晶度降低之外，乙基纤维素的基本特性和基本结构没有变化；EC分子量的大小影响纳米微球的粒径大小、粒径分布和对药物的包覆效率。

Yet without radical change, the constantly increasing cost of caring for an aging population with ever-more advanced technologies risks bankrupting the government, which bankrolls payment for the poor, for children, for its own employees and for the old.

但是如果没有大的变化，对老年人不断增加的成本，伴之以更先进的可以可能会导致政府的破产，去为穷人、儿童、自己的员工和老年人买单。

One ofthe most are the most innocent: the worlds poorest and those yet to be born.

气候变化带来的最残酷的讽刺之一，就是最受伤害的人，恰恰就是最无辜的人--那些世界上最穷的人们和那些还没有出生的人。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
