(2) Most of the abnormal distribution of Geochemical elements are along concealed fault or appear at fault crossing . This geochemical elements contain Hg、 As、B、 Bi、 Sb in soil and K、F、Na、H_2SiO_3 in water.

Among all the cases of AVRT, there were 32 cases of concealed accessory pathways (CAP) and 28 cases of WPW(Wolff-Parkinson-White syndrome)(adout 53.3%,46.7%,respectively).

Facing this increasing green waves, developed countries have to change its traditional trade measures, beginning to find a new and more concealed trade protection tools, In this case, green barrier came into being.

80% of the parathyroid glands are situated in tile normal yet concealed position: the upper pair, above the mid of the posterior margin of the lateral lobe of the thyroid gland, while the lower pair, near the inferior 1/3 of the posterior margin of the lateral lobe.

But his existence-ontology remained the concealed subjective metaphysics,one more concealed identical philosophy,the essence of which was anti-dialectics.

It is very difficult to detect and control because of its highly concealed life history.

Also, they kill the hosts in a concealed but safe position after the hosts cocoon or build their pupal cells.

A passive subject concealed from an active participant information kept in mind, whereas the latter subject aimed at detecting the information significant for the partner.

At the same time, the phenomenon of unconscious decision-making by an active partner was observed, which possibly took the form of an insight into the information concealed by the passive subject.

Tea-bagworm is an important pest of tea-plant in some tea growing districts in Anhwei, Chekiang, Fukien, Taiwan, and Hunan Provinces. The larvae infest the leaf, bark and husk of fruit, causing a considerable damage to the tea plants. The present paper deals with the general morphology, biological investigations and control measures of the pest. Both laboratory and field trials were conducted at the Chekiang Agriculture College and at Lung-thing (龙井) Tea Plantation, Hanchow, during the years 1953-1956. The tea-bagworm...

Tea-bagworm is an important pest of tea-plant in some tea growing districts in Anhwei, Chekiang, Fukien, Taiwan, and Hunan Provinces. The larvae infest the leaf, bark and husk of fruit, causing a considerable damage to the tea plants. The present paper deals with the general morphology, biological investigations and control measures of the pest. Both laboratory and field trials were conducted at the Chekiang Agriculture College and at Lung-thing (龙井) Tea Plantation, Hanchow, during the years 1953-1956. The tea-bagworm gives two generation annually and over-winters in larval stages. The male moth is winged; the female is wingless, concealing itself and depositing eggs in the case. After hatching, the larva leaves the case, then weaving a new conical shaped case with a few fragments of tea leaves. Under sunshine the larvae usually stay on the underside of the tea leaves and among the tea bushes. There have been found hymenopterous larval parasites, of which five are Ichneumonids and one is Chalcid. These parasites usually cheek the outbreak of the second brood of the pest. Basing on results of experiments performed, the following measures of control are suggested: 1. Spraying with 6％ wettable 666 at the rate of 1:200-400 dilution after the picking season, gives promising results. There appeared to be no disagreeable odor or taste of 666 in the leaves sprouted out from sprayed buds. 2. Spraying with Derris and Pyrethium, during the picling season. 3. Hand-picking the larval cases and hanging cases to potect the hymenopterous parasites.

This paper attempts to answer the following two questions: (1) Is it possible to derive the law of distribution of hydrological frequency theoretically(2) What type of distribution curve should be adopted as the model of hydrological frequency curve and how to determine their parameters? The results obtained may be summarized as follows: 1. Hydrological phenomena are time series with concealed periodic fluctuations. The results from statistical analysis based upon the current assumption that hydrological phenomena are independent stochastic variables should be accepted with due considerations. 2. In view of the regional nature of hydrological phenomena, the current parctice of analyzing samples taking from a single station only is, in effect, to narrow the sampling field arbitrarily from a larger area to a point, thus reducing the accuracy of the statistical results. Hence, the synthetic utilization of the data of all stations within the hydrologically homo- geneous region is an important measure to increase the accuracy of statistical analysis. 3. The belief that the flood frequency obeys the binomial theorem or Poisson's theorem is but to mix up the priori with the empirical probability problem. The binomial theorem, being a powerful weapon to deal with the problems of priori probability, has not been adquately and properly utilized in the hydrologieal frequency analysis. 4. Analyses have been made of the nature of distribution of shydrologieal series on the basis of Kaptyen's derivation of the skew distribution, which indicate: (1) That the theoretical interpretation of the log-probability law of the hydrologic phenomena by V. T. Chow is not sound; (2) that hydrologic phenomena being results of very complicated meteorological and hydrological processes, it is impossible to derive theoretically the law of distribution for the hydrological series. 5. The view that the flood frequency obeys the Gumbel's distribution is theoretically not sound and also not verified by actual data. 6. According to the nature of the mathematical treatments applied, the method of description of the empirical probability can be classified into three systems: (1) The methods of the generalization of the characteristic factors of the distributions, such as Pearson's curves, Goodrich's curves, etc.; (2) The methods of the modification of a fundamental distribution by series and polynomials, such as Gram-Charlier curves. curves, etc.; (3) The methods of transformed functions, such as the log-probability law, curves, etc. It should be remarked that not only Pearson's and Goodrich's curves are frequency curves of empirical nature, but even the theoretical laws, such as the normal law and the log-probability law, will be aceepted as curves of empirical nature, when used as models for empirical probability problem. 7. Hydrological frequency analysis should not be mystified and made absolute. Instead of free selections, the models of hydrological frequency curve should be uniquely selected and specified. Statistical parameters should be determined not solely by the short period data of single station, but also by the synthetic utilization of the data of possible more stations. 8. It is recommended that one of the two types of distribution, i.e. the log-normal frequency curve with both sides limited and the Pearson's type Ⅲ curve, may be selected as unified models. The author suggests that the K-value corresponding to recurrence intervals of say 10~4, 10~5, or 10~6 years may be selected as the upper and lower limits for the log-normal curve. For Pearson's type III curves, C_s should be treated not as independent but as dependent variables of C_v. 9. The proper way to select and determine the model frequency curve is to see whether it fits well with the actual data of grouped stations (stations to be grouped by regions for rainfall data and by C_v for runoff data) and the reasonableness of the extrapolating part. 10. Suggestions on the method of determination of x and C_v: For point rainfall, iso-x map may be utilized, and the mean C_v for each hydrologicregion may be adopted in order to minimize the errors from single stations and to avoid the discrepancies in results obtained from the same region. With regard to flood frequency analysis, flood mark reconnaissance must be utilized to determine the magnitude and the recurrence interval of the unusual flood. The x and C_v values of the floods and runoffs of hydrologically similiar river basins may be compared. Besides, the reasonableness of the results of frequency calculations as well as of the statistical parameters adopted therein may be checked by comparing runoffs and point-rainfall values of the same frequency.
