ObjectiveTo study the contents and distribution of trace elements of Phellodendron chinense Schneid.

目的研究不同产地及生长年限川黄柏微量元素的含量及分布特征。

The results of cluster analysis showed that the samples could be clustered reasonably into three groups and the elemental distribution characteristics are related to the habitats of Phellodendron chinense Schneid..

结果川黄柏的特征元素为Al，Ca，S，Fe，Mn，Ni，Pb，Cd，不同产地川黄柏的微量元素呈现明显的地域性差异。

Gathered in different growth years and from different habitats in Sichuan. MethodsThe samples were determined by means of ICP/AES. The principal components analysis and cluster analysis of SPSS were applied for the study of characteristic elements. ResultsThe analysis results showed that Al,Ca,S,Fe,Mn,Ni,Pb,and Cd might be the characteristic elements in Phellodendron chinense Schneid.

方法采用ICP-AES法，对不同产地的川黄柏中16种微量元素的含量及川黄柏不同生长年限元素含量的变化进行测定，以微量元素含量为指标，用SPSS主成分分析法和聚类分析法对川黄柏中的特征元素进行分析。

The author found that the big piece-size muscovites of China are the normal muscovites; the small-size muscovites in the metamorphic rock area are mainly phengite. The Indian muscovites studied both big and small piece-size of muscovite, are normal muscovites. The surface activity of Indian muscovite substrate is higher than China ones. Acid is easy to erode paralleling to the direction of the muscovite substrate face. Although acid treating does not destroy the muscovite structure, the thermal stability of muscovite has be decreased.

研究发现我国白云母主要产地的大片白云母均为普通白云母，变质岩地区的碎白云母以多硅白云母为主；本文研究的印度的大片白云母、碎白云母均为普通白云母；印度白云母基片的表面活性高于我国白云母；酸处理容易沿平行于白云母基面的方向侵蚀，虽未使白云母晶体结构产生破坏，但造成了白云母热稳定性降低。

Nutritional composition and its genetic variance of Phyllostachys iridescens shoots were studied.

对不同产地的优良经济竹种红竹笋进行营养成分及其遗传变异研究。

Results There were some differences in the oil extraction rate and the physicochemical properties.

结果 不同产地降香药材中提取的降香油得率和理化性质均存在一定的差异。

Objective: To develop a HPLC-ELSD method for the quantitation of esculentosides A in Radix Phytolacca.

中文摘要：目的：利用HPLC-ELSD测定不同产地商陆药材中商陆皂苷A的含量以控制其质量。

This was identical with spatial distribution pattern. However, the relativity was not evident, baesd on the Mantel test between geographical distance and genetic distance of Picea crassfolia.

但是，对青海云杉各个产地群体的遗传距离与地理距离进一步做Mantel 检验表明，群体的遗传距离与地理距离没有显著的相关性。

The fingerprints of Picrorhiza scrophulariiflora Pennell from different places were analyzed and the same peaks were identified by HPLC/MS.

对不同产地的胡黄连药材进行指纹图语分析，通过HPLC-MS技术指认指纹图谱共有模式中共有峰的归属。

Plants and plantlike organisms not only pervade nearly every habitat on earth, they are of central importance to every ecosystem and to human populations.

植物和类似植物的有机体不只是分布於地球的每一个产地，它们对於每一个生态系统及人口极具重要性。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
