Basing on previous research, international production balance theory and the creation of FDI's GDP-effect index model and foreign investment's scale deviating degree model, this paper analyzes GDP-effect of FDI, the relative importance of its influencing factors and the difference of each factor affecting between the self-effect and spillovers of FDI in China with the method of PLS regression which can solve the problems of multicollinearity and little sample.

Comparing with conventional statistics, SVM based on statistical learning theory develop on the basis of structural risk minimization, research specially machine learning rule under the little sample.

The essential of GM(1,1) model is a kind of model to forecast under little sample and little information. The aim of the model is to get forecasted value with little error as soon as possible.

The sensitivity of detection could be improved when universal primers labeled by fluorescence (Cy3 or Cy5) were used to label little sample according to restriction display PCR.

Little sample solution were used. The relative standard deviation of results were less than 0.3%(n=11) for five elements,and recoveries were 98.9%~99.2%.

The MALDI process produces both positive and negative ions directly and very little sample is required.

The main advantages of this technique over conventional liquid-liquid extractions are reduced amount of organic solvent, little sample preparation, and larger sample throughput.

This method requires little sample preparation and has the advantage of not requiring large amounts of tissue.

Mineral-magnetic techniques are sensitive, require little sample preparation, are rapid, often grain-size indicative, and usually non-destructive.

However, since more sample can be loaded on conventional columns compared to microbore columns the advantage of improved signal-to-noise ratio can only be realised in situations where very little sample is available.

TAC-PS method and AC-PS method were used to determine urine and C. S. F. protein. The method of Micheal et al was modified. The standardized curve, recovery test, coefficients of variation within a day, color stability test and interference factors were studied. 32 normal fresh urine samples were examined. Reference values: AC-PS 2.68±1.78mg/dl urine; TAC-PS 3.04± 1.89mg/dl urine. We tested 20 patients' urine samples and 22 C. S. F. samples with TAC-PS and AC-PS. There is no statistical difference in results....

There is no statistical difference in results. We have found that TAC-PS and AC-PS have good practicability, requiring only a little sample, and are precise with little apparent bias. TAC-PS and AC-PS are able to determine urine and C. S. F. protein simultaneously. We recommend that these methods be used for routine laboratory tests.

By means of ultrasonic pulse, we checked the longitudinal and horizonatal ultrasonic velocity and ultrasonic modulus of elasticity of four species of wood, they are Pinus koraiensis, Larix dahurica,Faxinus mandshurica and Tilia amurensis, which are air dried.Correlativity between two ultrasonic parameter and the longitudinal compressive strength and bending strength of wood has been analyzed with monodic and dualistic regression. The results showed that:(1) The correlativity between the longitudinal compressive...

By means of ultrasonic pulse, we checked the longitudinal and horizonatal ultrasonic velocity and ultrasonic modulus of elasticity of four species of wood, they are Pinus koraiensis, Larix dahurica,Faxinus mandshurica and Tilia amurensis, which are air dried.Correlativity between two ultrasonic parameter and the longitudinal compressive strength and bending strength of wood has been analyzed with monodic and dualistic regression. The results showed that:(1) The correlativity between the longitudinal compressive strength and bending strength of wood is very close, whose correlative equation can be explained by monodic linear function y=ax+b or power faction y=ax~b.(2) We have also set up the dualistic linear or power function correlative equation between longitudinal ultrasonic velocity, density of wood, whose correlative degree is much closer than the correlative degree of monodic linear fuction. Its accumulative total error has also decreased.(3) The correlative coefficiency(r)between power fuction and linear fuction is almost same.(4) The corrclativity between the horizonatal ultrasonic parameter and longitudinal compressive strength is obvious, but the correlativity between the horizonatal ultrasonic parameter and longitudinal bending strength is not obvious.(5) We adopted the new method, which is named "equal spoke of first wave" and checked 2×2×3cm standard samples successfully, so it is possible to check the little samples.

TZ84 strain of HAV was inoculated onto human diploid cell strain 2BS and cultured for 8-10 days. Hepatitis A Antigen ( HAAg ) was extracted from the infected cells. It is used for preparation of HAV diagnosis ELISA kit. The competitive ELISA method was for the detection of Anti-HAV. It is simple, quick and needs only very little sample ( 10 μl only) . The result can be read within 1-2 hours. The coincident rate with Abbott kit was 95%. There were no false positive. The capture ELISA method was used for...

TZ84 strain of HAV was inoculated onto human diploid cell strain 2BS and cultured for 8-10 days. Hepatitis A Antigen ( HAAg ) was extracted from the infected cells. It is used for preparation of HAV diagnosis ELISA kit. The competitive ELISA method was for the detection of Anti-HAV. It is simple, quick and needs only very little sample ( 10 μl only) . The result can be read within 1-2 hours. The coincident rate with Abbott kit was 95%. There were no false positive. The capture ELISA method was used for the detection of Anti-HAV IgM. The coincident rate with Abbott kit was 97%, also with no false positive. This article also describes the results of application of these reagents to the clinical diagnosis and epidemi-ological survy of hepatitis A.
