All aforementioned cases entierely were proved pathological diagnosis using operation or lung centesis. Results: On the CT manifestation, lobulation sign and spiculation sign mostly appeared in the malignant nodules. The accurate rate of diagnosis was 75.6; sensitivity were 76.3%; specificity were 74.1%; positive predictive value were 86.5%; negative predictive value were 58.8%.

结果：86例SPN的Cr征象中，分叶征和棘突或毛刺征多出现于恶性结节，与病理和随访结果对比，螺旋CT薄层扫描并MPVR重建判断肺小结节良恶性的准确率、灵敏度、特异性、阳性预测值和阴性预测值分别为75.6%、76.3%、74.1%、86.5%、58.8%。

Guagzhou Chenliji Pharmaceuticel Factry,Guangzhou,Guangdong 510180）Abstract To establish a method for the identification of storax and the determination of cassia acid in storax by HPLC. Methods: TLC and HPLC were applied.

HPLC在适当的条件下，采用色谱峰检出法，TLC采用硅胶GF254薄层板，ψ(石油醚∶正己烷∶甲酸乙酯∶甲酸)=10∶30∶15∶1为展开剂，荧光及硫酸乙醇喷雾两次检出；定量采用ODS C18色谱柱（4.6 mm×150 mm×5μm），流动相：ψ=58∶42∶0.3，检测波长271 nm，流速：1 mL/min。

Slope stabilization treatment of this region including polyathylen strip method and thin layer hydrograsser method, some small slopes even have not been treated. A few of the treated slopes fail during heavy rainfall. The post method of treatmenting these slopes obviously doesn't function properly. The purposes of this research is to suggest suitable methods for gravel slopes, and consider slope behavior and stability.

当初公路沿线砾石边坡於设计阶段时，采用了包括植生带铺植工法及薄层喷植工法二种护坡工法，另部份边坡高度较小之路段未予植生处理；由於此路段边坡易受雨水侵蚀而形成侵蚀沟，并使其细粒料流失，造成边坡植生效果不佳，所采用之护坡工法无法达到其预期之效果，本研究目的为建议适合之工法应用於现地砾石边坡上，并探讨边坡之整体行为与稳定性。

METHOD: Radzx Stemonae tuberosae and Syringa reticulata Hara var. mandshurica Hara were identified by TLC, and the content of Baicalin was determined by HPLC. Agilent Eclipse XDB-C18 column (4.6 mm×250 mm, 5 m) was used, the mobile phase was methanol and 0.2% phosphoric Acid (45:55), flow rate was 0.9 mLmin^(-1), and the detection wavelength was 276 nm; the column temperature is 35℃.
