Space curve is one of the basic elements in geometric modeling, and its effective representation is the basis of modeling. Parametric representation based on features is a kind of high-level representation including semantic information. In Chapter 4, para- metric representations based on features for free form space curve are investigated, and a parametric model for the loop of plain knitted fabric is established, in which 5 parameters with practical meanings are used to represent the shape of a loop and the relationship between loops. A new shrinkage prediction method for knitted fabric are proposed based on the parametric representation and energy minimizing. Experimental results on some plain knitted fabrics illustrate the feasibility of the proposed method.

The views of this papers are: the lack of act-intent leads to the unestablished contract; whether the contract will be established under the different shapes of the lack of indication-intent should be considered differently, and the paper does it in detail; except the lack of important elements, the the lack of effect-intent doesn't lead to an unestablished contract, but leads to an invalid or withdrawed contract.

文章认为：行为意思的欠缺将使得意思表示不成立，导致合同不成立；表示意思欠缺时意思表示能否成立，不应该一概而论，并且针对不同情况的表示意思欠缺进行了具体分析；效果意思中除了要素欠缺，其他情况都不会导致意思表示不成立，但是可能造成合同无效或者可变更可撤销。
