摘要： A system and method for measuring the modulation between a magnetic head and a magnetic storage medium, such as a disk, is disclosed. A magnetic read/write head is positioned above a magnetic storage medium at a given flying height. The magnetic read/write head reads a signal from the magnetic storage medium. A tester measures an alternating electric current between the magnetic read/write head through the slider and the magnetic storage medium. A computer may then calculate the modulation by the magnetic read/write head based on the alternating electric current. A DC voltage to the head may be applied to lower the flying height of the magnetic head.

摘要： A computer-based learning system uses knowledge points organized with a predefined multilevel arrangement. Each knowledge point has an information set which may include a knowledge content, an evaluation content and a solution content. For a given knowledge point, the learning system provides the knowledge content and evaluation content, analyzes the user's answers to the evaluation content and determines the next knowledge point to be studied by the user based on the user's answers and the predefined multilevel arrangement of the knowledge points. The learning system thus provides a different learning course for different users to achieve individualized learning. User's learning history may be recorded to facilitate reviews by the user and improve the selection of the next knowledge point. Users may provide feedbacks on knowledge contents and evaluation contents, and may even suggest their own knowledge contents and evaluation contents to improve the learning system and user participation.

摘要： A method and a device for multithread to access multiple copies. The method includes: when multiple threads of a process are distributed to different nodes, creating a thread page directory table whose content is the same as that of a process page directory table of the process, where each thread page directory table includes a special entry which points to specific data and a common entry other than the special entry, each thread corresponds to a thread page directory table, and the specific data is data with multiple copies at different nodes; and when each thread is scheduled and the special entry in the thread page directory table of the each thread does not point to the specific data stored in a node where the thread is located, modifying, based on a physical address of the specific data, the special entry to point to the specific data.
