The mainly factors of nosocormial infection were the underlying disease,abusing antibiotic drugs,aggressive operation and too long period of hospitalization.

When the calcinate time is too long, the LiMn2O4 was decomposed and Mn2O3 appears, which can affect the electrochemical performance of LiMn2O4.The results of electrochemical properties showed that the first discharge capacity of LiMn2O4 is bigger, the first discharge capacity of powders calcinated at 550℃ can be up to 124.4mAh/g.

Result:Average follow up period is 13.5 months. The excellent and good rate of joint function recovery is 95.5%,the rate of union is 98.2%,2 cases soft tissue were infected,3 intramedullary nails were too long,5 cases were rotated or shortening deformity.

Results Of 24 cases,2 with systic duct nub overlength(8.3%),3 with bile duct benign narrow after(58.3%),3 diagnosed as sphinctor of Oddi dysfunction(12.5%),operated by EST.

Result:In pubic union overlength group,the following indices were significantly higher than those of normal group( P <0.01):abnormal labor stage,abnormal fetal head position and abnormal labor.

Conclusion Bile evacuation time expanding and SO peristalsis heading abnormalty are the main causes which lead to biliary pain after cholecystectomy. Whereas bile evacuation time expanding,SO peristalsis heading abnormality and NDS overlength are mainly connected with biliary pain after cholecystectomy.

Affected factor of the reoccurrence of CA was age over 40 years,serving occupation,individual,selling,no-married sexual contacts,foreskin overlength,coinfection of other STDs,incorrect physics treatment,none antivirus and immunity regulator therapy,subclinic infection,alcohol drinking,and so on.

This time is often too long for certain biological liquids and solutions.

The survey interval of the Forest Resource Inventory of China (FRIC) is too long to meet the demand for timely decision-making required for forest protection, management, and utilization.

The disk model requires too long computer time, and the space charge wave theory is rather simplistic.

Of the nursing staff 100% were of the opinion that for the deceased patients, organ substitution therapy had continued too long.

In some prior studies, coronary occlusion was of too long duration such that the effects of infarction and stunning on the recovery of contractile function could not be distinguished.

The principal object of this paper is to present a direct method of finding the elevation of the exposuae station and conseqently the tilt and the swing, if desired, of an aerial photograph. Since the elevation of the exposure station is found, the plumb-line coordinate system can, in the sense of numerical calculation, be established however. The determination of the plumb-line coordinate system, relating to three ground control points and their cooresponding images on the photograph, means a determination...

The principal object of this paper is to present a direct method of finding the elevation of the exposuae station and conseqently the tilt and the swing, if desired, of an aerial photograph. Since the elevation of the exposure station is found, the plumb-line coordinate system can, in the sense of numerical calculation, be established however. The determination of the plumb-line coordinate system, relating to three ground control points and their cooresponding images on the photograph, means a determination of the position of the photograph in space. As can be seen the plumb-line coordinate system is definitely independent of the swing of an aerial photograph, the swing is not necessary in solving the space resection problem as the classical procedure done.The treetment in this problem involves only simple computations and produces exceptionally accurate results, as indecated in a numerical calculation during the preparation of this paper. Owing to the impossibility of publishing the numerical example in whole length, only the final results are referred here for comparing:

This artical have discussed the process of the vacuum pulsing carbur- izing and the charasteristic of this process. A vacuum furnace with a water cooled wall and a interior heater was used to study the effect of various factor-time, temperature, the interior pressure of the furnace at the carburizing period and the ratio of the diff- ussing period to the carburizing period-on the results of vacuum carbu- rizing. According to the results of tests, some opinions were made. The rate of vacuum carburizing is four...

A vacuum furnace with a water cooled wall and a interior heater was used to study the effect of various factor-time, temperature, the interior pressure of the furnace at the carburizing period and the ratio of the diff- ussing period to the carburizing period-on the results of vacuum carbu- rizing. According to the results of tests, some opinions were made. The rate of vacuum carburizing is four times faster than that of reg- ular carburizing. The carbon content in the surface of the carburising layer can be controled by changing the ratio of diffussing period to car- burizing period. The quality of the vacuum carburizing is much better than the regular carburizing.

Analysis of the principle of velocity ambiguity eliminator used in early instrumentation radar has shown that the smoothing time required is too long. The optimum algorithm used as software in radar system is analysed and it is found possible to reduce the smoothing time. A new hardware design is developed which by use of approximate optimum algorithm has made the smoothing time approaching to the computing time in general computer by software. An improvement is made on hardware design for eliminating velocity...

Analysis of the principle of velocity ambiguity eliminator used in early instrumentation radar has shown that the smoothing time required is too long. The optimum algorithm used as software in radar system is analysed and it is found possible to reduce the smoothing time. A new hardware design is developed which by use of approximate optimum algorithm has made the smoothing time approaching to the computing time in general computer by software. An improvement is made on hardware design for eliminating velocity ambiguity, in this case the time required is about a fourth as compared with the old designs.
