Study on Pothook of City Construction Land Increase and Rural Residential Land Decrease;

The structured designs of triggered hook and corresponding bumper were given.

The paper presents an approach to detect the existence of system call hooks set by Trojan horses based on the locality and determinacy of execution flows,and the analysis of system function call labs in both user and kernel levels,then designs and realizes corresponding prototype.

The implementing processes of vector save and hook control algorithm are illustrated detailedly.

The tuckstones with broken end and bearing plate for breast wall can be replaced without demolishing breast wall during cold repair.

Taking the guide-lock pothook used in automobile as an instance, combing with the special process character of die design, the process and die structure are analyzed, and the critical points of die design are introduced as well.

The struction and forming process of the spring hanger are analyzed,the multi-position progressive die is designed,the layout of product and die struction are stated.
