In the mycorrhizal inoculation test, the total dry weight of inoculated coneflower was more than control. The concentration of cichoric acid in the leaves of inoculated coneflower, 472.520 μg/mL was significantly higher than uninoculated control 245.638 μg/mL.

在菌根菌接种实验中，接种菌根菌的紫锥菊总乾重比未接种菌根菌的紫锥菊高，实验中也发现VA组叶子cichoric acid浓度为472.520

The results were as follows:The embryo-bud length, embryo-shoot length, embryo-shoot number and dry weight of embryo-shoot of maize inbreed line decreased evidently under osmotic stress within germinating period. So the germination date was delayed, the germination rate and viability decreased.

研究结果如下：在萌发期渗透水分胁迫条件下，玉米的胚芽长、胚根长、胚根条数、胚根干重等均有明显的下降，因而发芽时间延迟，发芽率下降。

Compared with Jia 948, Lianzhen 11 had greater root dry weight, root length, root surface area and more lateral roots.

与嘉948相比，连珍11具有较大的根干重，根长，根表面积和侧根数量。

The root dry matter accumulation was affected more intensively by Zn(superscript 2+) than the plumule, and which indicated that the root was more sensitive to exterior Zn(superscript 2+).

结果表明，外源Zn(上标 2+)供应可显著提高幼苗根和芽的干重，对小麦幼苗根的影响大于对芽的影响，根对Zn(上标 2+)更为敏感。

In the low B condition of the soilless culture, rapeseed seedlings were short of B, the seedlings were short and the leaves were malformed and the weight of the shoots decreased, the branch roots were fewer and snuff color, the weight of roots decreased, and the length of root and the ratio of shoot/root decreased, too. However, the high B- efficiency type of rapeseed had the a great ability to the low B stress, the growth of shoots and roots were better than the low efficiency, and the B concentration range of the rapeseed varieties which responded to the B scarce was 0.001 mg/L to 0.01 mg/L.

营养液培养条件下，苗期缺硼，甘蓝型油菜植株瘦小，叶片皱缩，地上部生长量下降；侧根少且呈现黄褐色，根重、根体积、根长以及根冠比下降；高效品种具有较强的耐低硼胁迫的能力，表现为同等缺硼条件下，对高效品种地上部和根系生长的抑制作用都相对较小，且品种间对缺硼反应差异最大的硼浓度范围为0.001mg／L—0.01mg／L。

The item adopts many high and new-technologi es , include extract from innocuous solvent, vacuum concentrated, accumulate by membrane, separate by macroporous adsorptive resins, recrystallization, vacuum or spray drying etc, it can extract refined radices puerarire starch, radices puerarire isoflavone and radices puerarire element from puerarire.

项目采用无毒溶剂提取，真空浓缩、膜富集、大孔吸附树脂分离、重结晶精制、真空或喷雾干燥等高新技术组合的新工艺，从葛根中综合提取葛根淀粉、葛根异黄酮及葛根素。

From the research of the kerogen carbon isotopes of the coal-measure strata in some basins of China (the Carbo-Permian in the Ordos basin, the Triassic in the Sichuan basin, the Jurassic in the Jungar basin and Turpan-Hami basin, the Tertiary in the Yingqong basin) it can be indicated that the Type Ⅲ kerogen has a wide δ〓C range from -21. 2‰ to -27. 6‰, averaging -25‰, which is more enriched in 〓C than sapropel and mixed kerogens.

对我国一些含煤盆地（陕甘宁石碳－二叠、四川三叠系、准噶尔侏罗系、吐哈侏罗系、莺琼盆地第三系）的煤系地层干酪根碳同位素研究表明，煤系地层的干酪根碳同位素组成δ〓C值分布范围为－21.2～－27.6‰，说明其变化范围较宽，平均值为－25‰左右，相对腐泥型干酪根和混合型干酪根较明显地富重碳同位素。

The results showed that the growth of Jinguang plum seedlings were remarkably restrained by salt stress. With the increasing of salt concentration, the plant height, leaf area, leaf fresh weight, leaf dry weight, stem dry weight and root dry weight were remarkably decreased, and the chlorophyll content, photosynthesis rate, transpiration rate and stomatic conductance in leaves were declined too, but the intercellular CO2 concentration was inclined.

结果表明盐胁迫抑制了金光杏梅幼苗的生长，随着盐浓度的升高，金光杏梅的株高、叶面积、叶鲜重、叶干重、茎干重、根干重均显著降低；叶片叶绿素含量、净光合速率、蒸腾速率、气孔导度亦显著降低，且盐浓度越高，下降幅度越大；细胞间隙CO2浓度随着盐浓度增加而增大，表明盐胁迫下非气孔因素是导致金光杏梅叶片光合速率下降的主要原因。

A fully automated simultaneous determination of nitrate and nitrite in water samples by sequential injection analysis based on the Griess diazo-coupling reaction and the formed azo dye for nitrite at 540nm and reduction to nitrite using coppered cadmium column.

用顺序注射分光光度法，通过一次进样。同时测定硝酸根和亚硝酸根。亚硝酸根是根据格里斯重氮－偶联反应，形成偶氮染料后在波长540nm下进行检测。而硝酸根则通过镀铜镉粒还原柱还原为亚硝酸根后进行测定。

This old man, he played three, He played knick-knack on my tree; With a knick-knack paddywhack, Give a dog a bone, This old man came rolling home.

与小玩意儿，稻重击，给狗一根骨头；这个老人回家了辗压。这个老人，他演奏了四；他在我的门演奏了小玩意儿与小玩意儿，稻重击，给狗一根骨头；这个老人回家了辗压。

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。
