Result:Therpeutic outcome and complications of the former were obviously better than the latter in the satisfactory rate 87.5% to 76%,the infection rate<8%,the breakage rate <16%,the avascular necrosis of the humeral head in four-part fractures rate 33.3%～60%, P <0.05 Conclusion:There are various methods to treat the proximal humeral fracture.

Using Neer fracture classification system,there were 69 cases with two-part fracture,(among them,65 were surgical neck fractures and 4 were anatomical neck fractures),47 with three-part and 11 with four-part.

18 cases of proximal humeral fractures in group B included 3 cases of Neer two-part fractures, 9 cases of three-part fractures, and 6 cases of four-part fractures. The true cases of common X-ray and 2D-CT were 7 in Neer three and four-part fractures.

The four-part cent points out the government at resolve the front the our country the rigorous employment problem, should at control the jobless rate with add the employment opportunities and make use of the public finance policy, currency policy to adjust to control the jobless rate and protect to take up employment the minority community and provide to start a business the environment and support the employment with income policy fair, the 6 : Positive development manpower capital develops to adjust to control the function positively.

The study shows, under vacuum maceration, the temperature of maceration and brazing may be decreased to 1050℃ and matrix has good performance of maceration and brazing by using Cu—Ni—Mn—Sn four-part alloy whose ingredient is very strict.

The four-part cent is a problem that "CPE" human resource development design, aiming at primarily the "CPE" human resource develop the inside esse, developping the project proceeding design to the "CPE" human resource;

In this four-part paper I attempt to 'recover' the notion of debate as a 'method' of philosophical analysis for the international studies.

A four-part 85-item orally administered children's Sex-Role Expectations and Awareness Scale was developed.

This paper provides a four-part definition to permit examination and comparison of disease categories in any system, including biomedicine.

Among these examples, six assembly sequences for a four-part packing system; two assembly sequences for a five-part shaft bearing system; 373 assembly sequences for a seven-part clutch system and assembly states have been investigated.

A study of mental health administrators and systems utilizing a four-part rural/urban taxonomy

By adding quality training to outdoor teaching,the origi- nal four part teachin were changed to five part.The results of statistical analyses done before and after exper- iment showed that it had significant effects on recising sports skill and score of physical quality,and fair effects on pulses and vital capacity of body.Comparing with the controls,it was proved that this made good results for grasping sports technical skill.Thus,it was justified that adding physical quality training could make student's physique...

By adding quality training to outdoor teaching,the origi- nal four part teachin were changed to five part.The results of statistical analyses done before and after exper- iment showed that it had significant effects on recising sports skill and score of physical quality,and fair effects on pulses and vital capacity of body.Comparing with the controls,it was proved that this made good results for grasping sports technical skill.Thus,it was justified that adding physical quality training could make student's physique strong more quickly,and it was advantageous to training of “three fundaments”,and it had significant advantages to training of will and character.

In this four-part paper first, the so-callec "paradox" negative IP effect and the studies on it by other geophysicists are introduced. Then, on the bases of equivalent resistivity method, the formulas for the potential, field intensity, and current density of the secondary pollariza-tion field are developed and used to calculate the anomaly for given parameters by means of linear filter method. Various maps are plotted from the calculation. Using these maps, we analyze the distribution of secondary polarization...

In this four-part paper first, the so-callec "paradox" negative IP effect and the studies on it by other geophysicists are introduced. Then, on the bases of equivalent resistivity method, the formulas for the potential, field intensity, and current density of the secondary pollariza-tion field are developed and used to calculate the anomaly for given parameters by means of linear filter method. Various maps are plotted from the calculation. Using these maps, we analyze the distribution of secondary polarization field from the viewpoint of physics and present a direct, and physical explanation. Thus the mystery of negative IP effect is solved. Finally, the objectiveness of such effect is proven by the data from soil-tank experiment conducted by us. Furthermore, the quantitative interpretation data by inverse calculation agree with the actual parameters. On the other hand, we have the negative IP effect on two electrode array and over mixed layers.

This paper,the four part of“the analysis of errors and the inspection groups in hobbing gear”,mainly discusses the composiition and compensation of errors,mathematical model and its geometric meaning when both the geometric and the kinematic eccentricity occurrs in hobbing.With the help of the com- pensation,it is possible to decrese thee effect of errors on machinihg precision.
