Expression level of rhGH could reach 250 mg/L culture solution by means of selecting components of original culture media, components of supplemental media, volume of supplemental media, the time of supplying supplemental media and supplying speed of supplemental media, secretion rhGH was found to represent 44%~54% of the total proteins in periplasm, and the fermentation time was reduced to 8 hrs.

通过对发酵培养基成分、补料成分、补料体积、补料时机和滴加流速的选择，分泌表达rhGH的量可达到250 mg/L，占周质蛋白的44%~54%，发酵周期缩短为8小时。

However, with the rule, the EPA can focus on pesticidal components of packaging while the FDA regulates nonpesticidal components.25

可是，因为有了这项规则，环保署可以主要关注有杀虫剂成分的包装材料，而食品药品署管理另一部分。

We established the statistical models for this site with the flux components, NDVI and other impact factors (precipitation, photosynthetically active radiation), and we validated the model at the site. The results of validation indicate that the model we established can well simulate the characteristics of flux components.

3利用生长季期间的NDVI时间序列数值，在1：100万中国草地资源数据的基础上进行聚类运算，在典型高寒草甸区域上划分出与海北通量观测塔所在处具有相似NDVI时间动态变化的区域，将此区域作为我们的通量扩展区域。

The Platanus pollen allergen had six kinds of main proteins and the proteins of 50, 39, 22 kd in the first peak were the major allergenic components and that of 16 kd in ascending part of second peak was the minor allergenic components.

结论悬铃木属花粉变应原含有6种主要蛋白成分，第一峰的50、39和22 kd的蛋白质为主要致敏组分，第二峰升段的16kd蛋白质为次要致原。

In conventional seismic data processing, the earth is regarded as prefectly elastic medium.However,the pores of stratum rock often contain fluid. So, when the seismic wave propagates in it, there are energy attenuation and phase distortion related to frequency. Moreover, the attenuation, scattering,and dispersion of high-frequency components are far higher than that of low-frequency components.

常规地震资料处理中把大地看成是完全弹性介质，实际上，地层岩石孔隙中常常含有流体，当地震波在其中传播时要发生与频率相关的能量衰减和相位畸变，且高频成分的衰减、散射和弥散远高于低频成分。

Even carbon number alkenes, phthalic esters and nitrogen heteroatom-containing components were detected in the elution fractions, while such components were not detected without silica gel column separation, indicating that preseparation is very important for increasing the sensitivity of GC/MS analysis.

各洗脱馏分用GC/MS分析，其可测成分与直接检测相比，多检测出偶碳烯烃、邻苯二甲酸酯类和含氮化合物等，表明合适的预分离对提高GC/MS分析的灵敏度非常重要。

MethodsIn the solvent of 1 mol/L NaOH,using the reaction of the total components of water-soluble phenolic acidity in Danshen and the NaNO2-Al(NO3)3,the total components of water-soluble phenolic acidity in compound Danshen preparation(calculated with protocatechualdehyde )were determined by colorimetric spectrophotometry.

方法利用丹参中水溶性酚酸类成分与NaNO2-Al(NO3)3在碱性条件下的显色反应，比色法测定复方丹参制剂中水溶性酚酸的总量。

The research aimed to discussed the differences of main nutrition components among wild and cultivated Pteridium aquilinum var. latiusculum and common vegetables. Some main nutrition components of wild and cultivated Pteridium aquilinum var.

［目的］探索野生蕨菜和栽培蕨菜以及常见栽培蔬菜所含主要营养成分的种类和数量的差异。

The mechanisms and mechanical components in general use are mostly used long-term and recurrently , and most of these mechanical components bear long-term loads and alternate loads .

普遍应用的机械，设备和机械构件，一般都是长期使用和循环使用的，运动部件大多承担长期交变载荷。

A historical region of southwest France between the Pyrenees and the Garonne River. The duchy of Aquitaine was joined with France after the marriage of Eleanor of Aquitaine to King Louis VII in1137, but its possession was disputed after her subsequent marriage to Henry II of England.

阿基坦法国西南部一个历史地区，位于比利牛斯山和加隆河之间，在1137年阿基坦的埃莉诺与国王路易斯七世结婚之后阿基坦公国加入法国，但当她再嫁英国亨利二世后，其归属权便受到争议

There are moments when I look at the smiling , happy faces of my expectant staff and wonder how they will cope when confronted by an outraged housemaster along with an unrepentant and recalcitrant bleached blond teenager in 18 years ' time .

有时候，我看着那些满怀期待的员工微笑，幸福的脸，想着当他们遇到一位愤怒的宿舍管理员和一位不知悔改，叛逆，而且将头发染成白色的18岁少年时，他们会如何处理。
