This paper presented the research and exploration of mechanism and technics as well as the design of the magnetic circuit of this new compound machining, based on above, establishing the parameter model, meantime, analyzing influential effects on productivity of magnetic and EDM compound machining the holes through large numbers of experiments, including velcoity contrast experiments of pre-compound and after-compound machining with the change of current, velcoity contrast experiments of pre-compound and after-compound machining with the change of magnetic induction, velcoity contrast experiments of pre-compound and after-compound machining with the change of impulse width, experiments of the superficial roughness, experiments of the Electrode wastage, and intersectant experiments analysis as well as the change experiments of current waveforms. Through a number of experiments we analysed the influential effects of magnetic and EDM compound machining, compared the factors with EDM by oneself. A large of experiment records and deducibility have demonstrated that the productivity of magnetic and EDM compound machining is developed by 20%～400% than traditional EDM.

本论文对磁场电火花复合加工这种新的复合加工的机理、工艺和复合加工的磁路设计进行了研究和探索，在此基础上，建立了磁场电火花复合加工的参数模型，同时通过大量的随着电流变化磁场电火花复合前后加工速度对比实验、磁感应强度变化时的加工速度变化实验、随脉冲宽度变化的加工速度实验、表面粗糙度实验、电极损耗量实验、磁场电火花复合加工正交实验分析、电流波形变化等实验，实验分析了影响磁场电火花小孔加工效率的因素，并且跟单一的电火花加工中的影响因数进行了比较，大量的实验数据和理论推导证明磁场电火花复合加工比传统的单一电火花加工的效率提高了20％～400％左右。

Depending on this, we concluded the difference of Zeitgeist between mid ages and pre-modern literature on merchant spirit: either the dominant idea of the mid ages poetry is "powerful commerce leads to underdeveloped farming", or the idea that focuses on "mutual benefits" based on court and local policy; but the beginning of pre-modern literature----- the agreement between scholar-bureaucrats and merchants comes from lightheartedness, joy, sentimental expression and lyrical description expressed by middle period of Ming merchant poetry that deeply reflected the citizenly cultural spirits. Contrast to the poetry on merchant of middle literature, this is the ultimate transformation, showed the mostly characteristic of pre-modern literature priorly .

以此为界说，可以归纳出中世、近世涉及商贾诗歌的不同的时代精神：中世时期的诗歌或以"贾雄则农伤"为其主导思想，或主要着眼于朝廷与地方政策的层面张扬"农商兼利"的思想；而近世文学的起点———明中叶涉及商贾的诗歌往往在自由自在、安享快乐及张扬情欲、舒展性灵等方面有士商心灵的契合，在深层次上反映了市民文化精神，相对于中世涉及商贾的诗歌有根本性的转变，较早地显示出近世文学的主要特征。

Sub-articles 24 and 26 of UCP 500 allow for two scenarios:(1) where the transport document (non-negotiable sea waybill or multimodal transport document) bears a pre-printed wording to the effect that the goods have been loaded on board (the question relates to sea shipments) or similar, then this date is deemed to be the date of shipment (the emphasis being ''pre-printed'' and not by an addition at a later time); and (2) where the transport document (non-negotiable sea waybill or multimodal transport document) bears a pre-printed wording to the effect that the goods have been ''received for shipment'' or similar, then the document should bear a separate notation showing the date the goods were shipped on board.

"UCP500的第24条款项和第26条款项允许有两种情形：（1）如果运输单据（不可转让海运单或多式运输单据）带有预先印就的货物已装船词语（这个问题与海洋运输有关）或类似词语，该日期将被认为是装运日期（这里强调的是"预先印就"而不是后来增加的内容）；（2）如果运输单据（不可转让海运单或多式运输单据）带有预先印就的货物已经"收妥待运或类似词语，那么单据应当带有一个表明货物装船日期的单独的批注。

Their sex proportion、pretransplant Hb、pre- and post-transplant BP、diuretic therapy、immunosuppressive drugs、native kidney nephrectomy、pre-transplant lymphotoxin cross test and prePTE S cr/BUN were recorded and analysed.
