The results showed that the distribution pattern of bamboo was an aggregated pattern in population (α>0, β=1), and the basic component of distribution was proved to be "individual group" (α>0), which approached to be random distribution (β=1).

Five aggregation indice were used and the result of Taylor's spower rules and Iwao's M\+*/ regression were analyzed. Results indicated that the spatial distribution pattern of yellow rust of turf grass was aggregation distribution and individual group.

In the seed orchard of larch,the spatial pattern of larva is aggregated distribution,the basic component of this distribution is individual group,and the group diffusion is aggregated diffusion.

The results obtained by measurement of the indices of aggregation intensity, such as analysis of Iwao's patchiness regression between m and m, Taylor's power law and so on, indicated that the spatial distribution pattern of C. chinensis on cucumber was aggregation distribution and its basic component was individual group.

The individual group sizes of cocoons were measured and the conta-gious reasons were analyzed. It will provide the basis for field sampling , density estimationand pest forecast.

nov. in wild rice were aggregative distribution, the basic component was individual group. The sampling number of them N=(11.9688/m+0.8698)/D~2, N=(2.8043/m+0.6183)/D~2, N=(2.4566/m + 1.1873)/D~2, respectively.

Results as: the positive rate (37 90%) of HGV-M in hepatitis group was higher than that (13 40%) in the pulmonary tuberculosis group and than that (7 35%) in the blood donor group, P <0 01, moreover, all those in the above three groups were higher than that (1 40%) in the individual group, P <0 01;

puluinum Ewing larvae population was a loose individual group (α>0 or α′>0) in which individual group was aggregation pattern (β>1 or β′>1), and it was subordinate to negative binomial distribution witha common Kc(=0.3015).

Students in the individual group worked on the same activities by themselves.

Specifically, in a set of simulation studies, we systematically compared four decision strategies used by the individual group members: two linear, compensatory decision strategies and two simple, noncompensatory heuristics.

We review recent work on the accuracy of group judgmental processes as a function of (a) the competences (judgmental accuracies) of individual group members, (b) the group decision procedure, and (c) group size.

Three studies tested the hypothesis that an individual acting alone, compared with an individual group member, would be held more responsible for behavior leading to a negative consequence.

The Cp2o and V2o data can be expressed by equations having the general form: Y=AY+Σ Nk Yk+Σ(steric factors), where AY is solute independent and the Yk terms are the individual group contributions.

Guinea pigs were treated with chloro-butadiene,99.9% pure as determined bygas chromatography,by exposure to theconcentration of 37. 52±11. 44, 94.05±26.58,and 340. 22±83. 30mg/m~3, 2h per day for1, 3 and 6 weeks. The results were: 1. Histochemistry study of the livertissue:The amount of glycogen and theactivity of LAP,SDH, G-6PD, HKG,G-6P,5'-N,ICD, MAO decreased;the activity ofLDH and the amount of lipid increased. 2. Study of ultrastructure of the livercells: Changes were mainly hyperplasiaand dilatation of...

Study of ultrastructure of the livercells: Changes were mainly hyperplasiaand dilatation of smooth endoplasmicreticulum of liver cells,and rough endo-plasmic reticulum and mitochondria wereinvolved. 3. Histopathology study: The mainchange was massive necrosis. 4. Serum biochemistry study: The ac-tivity of OCT, ICD, GOT, GPT and LDHwas not different from that of the control.In the individual group,albumin wassignificantly different from that in thecontrol group,but the dose-responserelation was not present. The sensitivity of the four types ofstudied marker decreased according to theabove order. The essence of liver toxicity by chloro-butadiene could be summarized as follows:injury to endoplasmic reticulum andmitochondria,disturbance of glycogenand lipid metabolism and protein synthesis,interference of mitochondrial oxidativephosphorylation and citric cycle,anda final induction of liver cell fattydegeneration.

The spatial distribution of Panonychus citri is determined by means of chi square test in the recent survey made in four sample plots of Citrus reticul-ata. The results show that major sPatial distribution appears to be negative binomial distribution. Moreover, a further calculation of the aggregation degree indicates that all populations of Panonychus citri are spreading in individual groups. Stratified random sampling is then carried out in the upper, middle and lower layers of the tree canopy,and negative...

The spatial distribution of Panonychus citri is determined by means of chi square test in the recent survey made in four sample plots of Citrus reticul-ata. The results show that major sPatial distribution appears to be negative binomial distribution. Moreover, a further calculation of the aggregation degree indicates that all populations of Panonychus citri are spreading in individual groups. Stratified random sampling is then carried out in the upper, middle and lower layers of the tree canopy,and negative binomial distribution is also found in each layer, showing that the population density is the highest in the upper layer and the lowest in the lower layer of the canopy.

The results obtained by measurement of the indices of aggregation intensity(iaduding:CA.M* x,L/1+x)and analysis of the Iwao's M*-x regression and the Taylor's power rules showed that the spatial distribution pattern of Bradybaena similaris Ferassae(1821)in peanut fields was aggregation distribu-tion(CA>0,M*/x>1 and M*=0.14598+1.39095x,r=0.9955***,P<0.001)The basic composition of the distribution was individual group(α>0,β>1).And the aggregation degree increased(or decreased)with increase(or decrease)in...
