The results indicated :there were highly significant differences in 45 genotypes for all the root lodging resistance traits; the GCA was more important than the SCA in the genotypic variations for root resistance traits and the GCA differences were rather remarkable in the same trait of the various inbred and in the same inbred of the various traits; the positive genetic correlation.

Preliminary studies on relationship between root morphological traits,yield per plant and lodging in Brassica napus L.;

Studies on the Influence of Lodging to Germinating in Barley;

The effect of special wind load on wheat stem lodger;

Dynamic Studies on Maize Stem Lodger Resistance;

Dynamic Analysis of Rice Stem Lodger Resistance;

Impact of the fabric performance on the rule of looseness of lapel collar;

According to the looseness which is the difficult part of the lapel collar design,the relationship between the fabric properties and the looseness of lapel collar is studied and analyzed.

The quantitative relationship between fabric properties and looseness amount of lapel collar was studied with the help of measuring the six indexes of mechanical property on the facrics.

Influence of overturned collar width on gradient data of lapel collar;

Calculation method of the gradient data of lapel collar;
