But when the Master himself came by me as I said just now, and said we should be all lost, I dreadfully frighted: I got up out of my Cabbin, and look'd out; but such a dismal Sight I never saw: The Sea went Mountains high, and broke upon us every three or four Minutes: When I could look about, I could see nothing but Distress round us: Two Ships that rid near us we found had cut their Masts by the Board, being deep loaden; and our Men cry'd out, that a Ship which rid about a Mile a-Head of us was foundered.

但我前面说过，当船长从我舱房边经过，并说我们都要完蛋了时，可把我吓坏了。我走出自己的舱房向外一看，只见满目凄凉；这种惨景我以前从未见过：海上巨浪滔天，每隔三四分钟就向我们扑来。再向四面一望，境况更是悲惨。我们发现，原来停泊在我们附近的两艘船，因为载货重，已经把船侧的桅杆都砍掉了。突然，我们船上的人惊呼起来。原来停在我们前面约一海里远的一艘船已沉没了。

For the first time, enantiomers of C2-symmetric 1,1 -spirobiindane-7,7'-diol were resolved with crude menthyl chloroformate by phase-transfer catalysis in the presence of tetrabutylammonium bromide. The reaction was carried out at 0℃-rt. The diastereomers of SPINOL bis-menthyl carbonate can be separated by simple crystallization using alcohol. The hydrolysis of the diastereomers was carried out via aqueous NaOH/EtOH solution.

首次通过相转移催化的方法对螺双二氢茚二酚进行了有效的拆分，用L--氯甲酸薄荷醇酯做拆分剂，以四丁基溴化铵为催化剂在0℃-室温下进行酯化反应生成非对映体衍生物，以乙醇作溶剂，通过重结晶的方法分离衍生物，在水-乙醇混合溶剂条件下，用强碱NaOH或KOH分别水解，制得相应的光学纯度大于99%ee的两个异构体SPINOL，其中总收率：--SPINOL，78.2%；--SPINOL，80.6%。

Finally, this study makes five suggestions:(1) Reinforce the consciousness and the specialistic techniques of the workers.(2) The workers must empower clients.(3) Stress the treatment in consultation.(4)Differentiate the type of clients who are sheltered.(5) Perfect the services and the policy about family treatment. We hope it can help for the treatment pattern for teenage prostitutes in the sheltery organization and prevent the teenage prostitute more successfully.

最后提出五点建议：一、加强工作人员的自我觉察能力与专业技巧；二、工作人员要有增进个案充权的概念与行动；三、著重辅导层面的处遇；四、区分安置的个案类型；五、健全家庭处遇的服务与政策；期供性交易少女安置处遇之参考，冀使儿少性交易防制工作更臻落实。

An inferior quality in the administration of personnel file, which finds expressions in a lack of individuality and innovation as well as a fake and inaccuracy in the contents and the superiority of politics over the professions. 2. A dissociation of personnel from file which results in an increase in unsolved files. 3. an unadjustment of the personnel file to the new situation which leads to a multiple of management featured by the "file following personal".

通过大量的调查研究，作者认为人事档案目前明显存在的问题主要有：一、人事档案材料内容质量不高，表现为千人一面、缺乏个性，更新滞后、内容陈旧，把关不严、难辨真伪，重政治轻业务等；二、人档分离现象日趋严重，&无头档案&增多；三、人事档案管理体制不适应新的形势，表现为管理体制上是多头管理，管理体系上仍为传统的三大类管理，管理方法上&档随人走&，管理模式上实行封闭式管理；四、人事档案管理方式陈旧、手段落后，仍以手工操作为主。

The heavy armored vehicle is supported by eight pairs of low-power repulsorlift skis along the rear section that constantly readjust to encountered terrain, propelled by four repulsorlift plates mounted under the forward carriage.

该重装甲车被装在尾部区域，始终调整自己以适应地形的八对低功率反重力装置支撑，由装在车架前方的四个反重力提升盘推动。16个起伏的skid盘（skid一词也是查遍了所有字典，包括专业的而没有合理的解释。

By using the pules echo ultrasonic technique with 10 MHz. the ultrasonic velocities of the amorphouse carbon and their pressure dependence have been measured in the pressure up to I GPa. We have calculated its second, third- and combinations of forth-order elastic constants, and have researched its Gruneisen constant.

本文报导了利用10MHz超声脉冲&回波重合法&，测量非晶碳的声速及其在1GPa压力以内的变化规律，得到非晶碳的二阶弹性常数，三阶弹性常数及组合的四阶弹性常数，从而进一步计算和研究非晶碳的Gr？
