Persistent bilateral leg pain with no history of back pain also suggests spinal tumor. Myelography with contrast media or CT scan with metrizamide is essential to detect intradural and intramedullary tumors.

持续性两侧小腿疼痛而无背痛病史，也提示为脊柱肿瘤，用造影剂作脊髓X线造影或用甲泛影酰胺作CT扫描探查硬膜内或脊内肿瘤是来可少的。

Persistent bilateral leg pain with no history of back pain also suggests inal tumor. Myelography with contrast media or CT scan with metrizamide is e ential to detect intradural and intramedullary tumors.

Comparing with the traditional way of stronger sulfuric acid ,The catalyst has its advantage of more effective on the synthesis,the operation is more safer, does not corrode the equipments and does not pollute the environment,and the recovering operation is simple. So it can be called a green method on synthesis of isobutyl acetate.

该催化剂与传统浓硫酸法相比，催化效果更好，作更安全，对设备无腐蚀，对环境无污染，实现了催化剂的重复利用，并且回收作简单，重复利用率高产率好，达到绿色合成乙酸异丁酯的目的。

The results show that jamesonite and pyrrhotite have good floatability in the pH range of 2-10 and marmatite has good floatability in the acid and it is difficult to separate these minerals. In the pH range of 6-8, the separation of jamesonite and pyrrhotite, marmatite is possible when using mercaptoacetic acid and mercaptoethanol as depressants. In case of the presence of Cu2+ ion, however, it is difficult to separate the three minerals. Infrared spectrum demonstrates that there are a number of function groups such as —SH,—COOH,—OH in the molecular structure of depressant.

结果表明：用丁黄药作捕收剂，脆硫锑铅矿和磁黄铁矿在pH 2~10范围内都有良好的可浮性，铁闪锌矿在酸性条件下可浮性好，三者分离困难；在pH 6~8之间，采用巯基乙酸和巯基乙醇作抑制剂，脆硫锑铅矿与磁黄铁矿和铁闪锌矿的分离是可能的；但铜离子存在时， 3种矿物之间的选择性分离是难以实现的。

No doubt ,our legislative and judicative activities must obey those rules ; many other theses also has talked about that. But the difference is , this dissertation not only has talked about the martime transport service rules under GATS , but also has introduced the new negotiation about maritime transport service in Doha. Next it pointed out the difficulties of the new negotiation and predication has been given. It hopes that this part will give somewhat help to people whose work related on maritime service .

第一部分介绍了 GATS 中的海运服务规则，无疑这些规则都是我国海运服务立法和司法实践应该遵守的，以往的学术论文对此也多有涉及，所不同的是，本文除 GATS 中的海运服务规则外还就海运服务新一轮谈判的情况作了较为详尽的介绍，指出了海运服务谈判存在的现实困难，并预测了海运服务谈判的前景，以期能为从事海运服务理论研究和实践工作的人员作一定的参考借鉴。

The research results showed that the effects of personality characteristics on kinesthesis position accuracy of elbow joints and stability of hand action were not significant,the kinesthesis position accuracy of elbow joints obviously increased by using the rationing motor load, but the stability of hand action did not obviously change.

研究结果表明：个性特征对肘关节动觉方位准确性和手动作稳定性的影响不显著；定量运动负荷可以使肘关节动觉方位准确性明显提高，而手动作稳定性变化不显著。

Dynamic inheritance of rice allelopathy on the root length of receiver plant lettuce (Lactuca sativa L.) and its genotype×environment effects were analyzed by using additivedominant developmental genetic models.

采用包括基因型与环境互作的数量性状加性—显性发育遗传模型，分析了供试水稻对受体植物莴苣幼苗根长化感作用的动态遗传及与环境的互作效应。
