成熟叶叶鞘同时还具有拒Cl~-能力。2外源物质对盐胁迫的缓解作用植物的耐盐性是一种综合机制，其对盐胁迫的适应也是多种多样的，作物的耐盐性是一种相当复杂的生理功能，是遗传特性与外界环境共同作用的结果，不同的外源物质对盐胁迫的缓解作用是通过不同途径实现的，因而很难用某一个指标来说明外源物质与耐盐性的关系。

Due to their modes to adapt to arid condition, ecological and physiological responses and the changes of structure are all different, but their mechanism to adapt to the sandy soil water changing is consistent, consequently they have more chances to exist in the entironment what has biggish annual wave of climate comparing to mostly plants that bourgeon in early spring.

由于对干旱生境的适应方式各不相同，其生理生态反应和结构的变化因种而异，但对沙土水条件的适应机理却是近似的，从而在年际气候波动较大的生境中，这几种植物较早春期萌发的大部分植物幼苗有较多的存在机会。

Adrenalin is a kind of nerve substance of catecholamine, which is an important parameter in human body and widely distributes in centrum nerve.

肾上腺素作为儿茶酚胺类激素的一种，是人体内一种重要的生理参数。

PAL activity, chitinase activity, total Polyphenol content and total Flavonoids content in soybean leaves induced by the same crude toxin and race were similar, it stated that the crude toxin is an important factor which can induce resistant substances, but the induced speed and the induced intensity by the crude toxin and conidium were different. Firstly, the induced speed of crude toxin which induced PAL activity and total Flavonoids content of resistant soybean varieties was faster than speed of C.

同一生理小种的粗毒素与灰斑病菌对大豆叶片内PAL活性、总多酚类含量、总黄酮含量以及几丁质酶活性等几种生化指标均表现出相似的诱导作用，由此可推断粗毒素是诱导大豆叶片内的PAL活性、总多酚含量、总黄酮含量以及几丁质酶活性产生变化的主要生物因子，只是二者在对抗性不同的大豆品种的诱导速度及强度上存在一定的差异。

This paper not only introduce mainly disserve, physiological races、filtrate resist disease data、mechanism of resist disease and pathological changes、prevention and cure synthetically and so on, but also advance some suggest of writer.

通过对1990~2000年这5种病害的危害情况、生理小种鉴定、抗病资源筛选、品种抗病机制及病菌致病机制、综合防治等方面研究进展的综述，笔者从宏观角度提出了一些建议性的观点。

The processing methods of dryi ng, pulverization, pelleting and ensilage are mainly discussed.

根据饲喂对象生理特点的不同，可采用不同的粉碎和制粒工艺参数；热喷、氨化是提高柠条营养价值的一种有效措施；青贮等生物学加工处理方法，因其操作简便、耗资小、处理后的柠条营养价值高等特点，成为柠条加工利用的一种新型方法。

Estrogen includes estradiol, estriol and estrone. Estradiol (E2)is the strongest active hormone of the three kinds of estrogen. It has very strong physiology function and extensive medical function to animal and poultry, but remain in animal food will endanger human health.

雌激素包括雌二醇、雌三醇、雌酮，雌二醇(E2)是3种雌激素中活性最强的一种，具有很强的生理功能，对畜禽有广泛的药理作用，但是在动物食品中残留会危害人类健康。

Y pretreatment on their leaves, the physiological effects of vitamin C, ethanolamine, cysteine, fucose and sodium benzoate were studied through design of randomized block and subordinate function values, and three best performance on improved its drought resistance chemicals were selected.

幼苗为试材，经叶片喷施药剂进行预处理后用PEG-6000溶液模拟水分胁迫，采用随机区组试验和隶属函数法，综合评价了维生素C、乙醇胺、半胱氨酸、苯甲酸钠和岩藻糖五种药剂对水分胁迫下香蕉幼苗叶片的生理影响，从中筛选出对有效提高香蕉抗旱性效应前列的三种药剂。

A new physiological race of leaf mould Fulvia fulva ( Cooke Ciferri 1.2.3.4.9 was detected by continuous investigating and sampling from tomato production in Beijing area for several years.

通过对北京地区番茄叶霉病菌生理小种分化的连续监测，发现了可侵染目前生产上主栽抗叶霉病品种的新小种。

There are distinct correlativity between chlorophyll content , soluble protein content and Rubisco content of the rice under the different N level. The three contents of different position leaf of jowar and maize presented one peck in the middle leaves floor, which gave them great matters for photosynthesis.

各施氮处理下水稻Rubisco含量、叶绿素含量和可溶性蛋白含量三者之间都存在显著的相关性；研究了高粱和玉米两种C_4植物不同叶位叶片Rubisco含量、叶绿素含量、可溶性蛋白含量，结果表明在营养生长期两种C_4植物叶片的这三个生理活性从上到下都呈现中间高两边低的趋势。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
