The authers give a brief account of the present situation and prospects for the application of immunochemical methods to agricultural sciences, inculding identification of species, diagnosis of animal and plant diseases, quantitative and locative analysis of substances of biological activity in living things, determinat...

本文介绍了农业科学研究中，在物种鉴定、快速诊断和检疫、生物活性物质的测定、性状标记物和次生代谢物的测定、食品和环境中残毒的检测、生物物质的定位等方面血清学技术的应用现状和前景。

Luciferin,as the light-carrier substance or the energy-transfer substance,plays an indispensability role on the luminescent system of luciferase in the biology illuminant.

在生物发光体内，荧光素作为直接释放光子的物质和能量的传递物质在荧光素酶发光体系中发挥着不可或缺的作用。

The result shown:the growth and development of P-deficient white lupine with cotyledons were not inhibited compared with the P-sufficient white lupine.

结果表明，子叶中的磷能使白羽扇豆在完全缺磷23 d的环境中，不仅没有使干物质的积累减少，反而使干物质的积累略有增加。

Compare with other flavonoid the inhibition effect of Luteolin is better than Quercetin and Genistein.

并且与其他类黄酮化合物比较Luteolin的抑制效果更胜於大众所熟知的抗氧化、抗癌物质物质Quercetin、Genistein。

He also led Lycian troops in the Trojan War, and in the Iliad was tricked by the Greek hero Diomedes into exchanging his gold armor for Diomedes' brass, the origin of the term 'Diomedian swap'.

This experiment was conducted to study the reasons of bovine low performance from one aspect of major matter and energy metabolism in high altitude regions. The index of nitrogen equilibrium, energy material, macroelement, microelement, ADE, AME, absorbance of phosphorus, MEm, average daily gain etc. were analyzed by field test and sampling.

为从主要物质和能量代谢方面揭示高海拔引起牛生产性能低下的问题，利用实地测试取样，对西藏农区14头牛的N平衡、能量物质、主要常量元素、微量元素、FHP、ADE、AME、P沉积、MEm、日增重等代谢指标进行了分析。

In every group, rabbits were subdivided into experimental and control subgroups. 2 Rabbits were bullets injected followed by continuous injected with 13C labeled leucine, glucose, and lactic acid; 3 Blood were drewed before and 150, 160, 170, and 180 min after the initiation of isotopes injection for material analysis; 4 Exhale gas were collected every 5 min in the first 30 min followed by every 30 min there after for material analysis; 5 After centrifuge in low temp the supernatant of the blood samples were collected and went through axon and anon exchange column treatment; 6 Treated blood sample was used for 13C labeled leucine, glucose lactic acid examination through mass spectrograph; 7 The exhale gas was collected for 13CO2 exam through gas-phase mass spectrograph; 8 CO2 total production rate (V13CO2), body various substances production, oxidation speed, and substances metabolic percentage all can be calculated through equations provided by references below; 9 Data was processed through student t test.

分亮氨酸、葡萄糖和乳酸三组各取健康新西兰兔16只，每组再分为高代谢脓毒症组和对照组两部分，建模方法同第一部分；2）三组分别先静脉弹丸式推注再持续灌注13C标记的亮氨酸、葡萄糖和乳酸；3）灌注前抽取动脉血作为背景值，灌注达150，160，170和180min分别抽取动脉血2ml用于质谱分析；4）实验开始后前30min中每5min收集呼出气一次，随后每30min收集呼出气一次，用于气相质谱分析；5）血样经过低温离心取上清液，过阳离子及阴离子交换树脂，再经衍生化处理；6）处理过的血样进入气相色谱－质谱仪，测量其13C标记的亮氨酸、葡萄糖和乳酸丰度；7）实验兔的呼出气通过13CO2气相质谱分析仪测定其中的13CO2丰度（E13CO2）；8）利用文献提供的公式算出CO2总生成率（V13CO2）以及机体各物质的通量、氧化速率以及物质代谢百分比等；9）数据分析处理采用t检验。

Antimatter is a different representation of matter that seems massless in different amounts of space and time.

反物质是另一种时间与空间中的看似无质量的物质的表现，事实上，我现在知道的并不足以回答这个问题，也许在五年之后可以。

Because we are living in a material world,and i am a material girl...

因为我们生活在一个物质的世界，所以我是一个物质女孩。。。

You know that we are living in a material world, and I am a material girl.

你知道我们生活在物质的世界里，而且我是物质女孩。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""
