As each department or one decision of the group of the region, the leading group of the county-level in the special position, it forms a connecting link. At the new situation, it is an important task before us, how to improve the whole performance of the leading group, to make it become politics really up to the mark, to have a democratic style of work, to open up the practical, and to be honest and high-efficient leading collective.

Higher vocational education is a kind of education with ability as center, as each kind of college higher mathematics that manages an important basic lesson of the special field of engineering course, how to meet this kind of ability mainly, use really for the reform of degree needs?

As far as each group concentration was concerned, 10% or 50% showed relatively stronger effects, and both conditioned medium of normal CMECs (N-CM) group and conditioned medium of ischemic/reperfusional CMECs (Rp-CM) group had statistical significance (P<0.05 or P<0.01).

The significant growth effects were obtained when the selenium content was 1.1mg as each goat was fed additional 100g of granule forage daily, and the daily gain was increased 211.4% (P<0.01), dressing percentage increased insignificantly, the selenium content increased 107.7% in liver, 200.0% in meat, and 13.7% in plasma respectively compared with that of the control group.

Yet as each professional group has developed its own system of theories and techniques the opportunity for actual mutual influence has dwindled.

As each new patient is treated, the volume of stored information increases, so the system possesses self-learning characteristics.

Each participant's secret shadow is as short as each secret.

As each joint actuator of a robot manipulator has a limit value of torque, the motion control system should consider the torque saturation.

As underlined at the outset, all other arguments and claims of the parties are beyond the scope of the present study as each of them obviously requires extensive study.

Complexone 111 as a reagent for the amperometric titration of nickel,proposed by (2) and Reilly(3),was studied in detail and applied to the determination of nickel in anode slimes.It was found that the titration can be made at any suit- able voltage between—1.2 to—1.8 volts.As each portion of the reagent was added to the titration cell,equilibrium was obtained within two minutes,and the overall titration pro- cedure could be finished within 20 minutes.It has the advantage over the dimethylglyoxime method...

Complexone 111 as a reagent for the amperometric titration of nickel,proposed by (2) and Reilly(3),was studied in detail and applied to the determination of nickel in anode slimes.It was found that the titration can be made at any suit- able voltage between—1.2 to—1.8 volts.As each portion of the reagent was added to the titration cell,equilibrium was obtained within two minutes,and the overall titration pro- cedure could be finished within 20 minutes.It has the advantage over the dimethylglyoxime method in which each stable reading was obtained in approximately 15 minutes.The method is sensitive because nickel can be titrated at a concentration as low as 3×10~(-4) M.Silver and copper,both present in anode slimes interfere and must be separated prior to the titration. The anode slimes was dissolved in concentration sulfuric acid.Silver was removed as silver chloride and nickel was precipitated as nickel-dimethylglyoxime in the filtrate.The precipitate was dissolved in 6N hydrochloric acid and then titrated.The results,as compared with both the gravimetric and the dimethylglyoxime amperometric method,were satisfactory. The procedure is simple and rapid and each determination can be finished within one and a halt hours.

The detecting of underwater acoustic waves by means of photographic techniqueis becoming attractive as the image can be processed by electronic computer or opticalequipment so as to increase the sesitivity of detection.The underwater acoustic signalscan be converted directly into visible image.As each pixel of the image is a two-dimensional function,it has more eigen information than is obtained by using generalpizoelectric transducer which usually gives information of one-dimensional functiononly.Therefore...

The detecting of underwater acoustic waves by means of photographic techniqueis becoming attractive as the image can be processed by electronic computer or opticalequipment so as to increase the sesitivity of detection.The underwater acoustic signalscan be converted directly into visible image.As each pixel of the image is a two-dimensional function,it has more eigen information than is obtained by using generalpizoelectric transducer which usually gives information of one-dimensional functiononly.Therefore it is advantageous to the increase of the signal-to-noise ratio.In the experiment described by this paper a spatial filter is used for processingthe image of the signal waves and the enhancement of the image is accomplished bycomputer.The processed image is photographed as shown attached.

If measurements are made many times on each of many objects,we can obtain a precision index describing the consistency of the observed values on each object;and obtain an accuracy index from the conditions which the observations must satisfy. Assuming that the observations are random samples from normal distributions,we can estimate the“accidental standard deviation”,a precision index,and the“systematic stan- dard deviation”,an accuracy index,of the observations using the technique of analysis of variance.This...

If measurements are made many times on each of many objects,we can obtain a precision index describing the consistency of the observed values on each object;and obtain an accuracy index from the conditions which the observations must satisfy. Assuming that the observations are random samples from normal distributions,we can estimate the“accidental standard deviation”,a precision index,and the“systematic stan- dard deviation”,an accuracy index,of the observations using the technique of analysis of variance.This paper analyzes these two kinds of standard deviations of horizontal angle measurements in classical geodetic traversing and triangulation with theodolites. Experimental traverses were run with 1″ theodolites and movable targets mounted on tripodes.The sides averaged 100m long.Systematic errors were found significant in F tests due to errors in centering the theodolites and targets.Accuracy was improved and systematic errors were made insignificant,when angles were measured in the following way.Each angle of the traverse is measured several times,each time with a different position of the horizontal circle,such as each time the circle is shifted 60°,The theodo- lites and the targets are recentered after each time the angle is measured and before the next measurement. A triangulation net of second order was analyzed.The sides averaged 8 km long.The angles were measured by the method of directions using 15 positions of the horizontal circle with T3 theodolites.The result shows that the ratio of systematic and accidental stan- dard deviations of measuring an angle is about 3.7:1.Possible ways of making systematic errors insignificant are discussed.The usual belief that if angles are measured by the method of directions the triangulation net should be adjusted by the direction method is groundless.
