At present, logistics finance mainly includes several business models: (1) Warehouse receipt pledge mode; (2) confirmation warehouse business model; (3) Financing warehouse mode; (4) Advance payment mode.
During advance payment mode, financial institutions depend on logistics enterprises more deeply.

Research and Development of Online Course Systems Decai Zhao1, Boyang Xie2 1College of Information and Engineering, Hebei North University, Zhangjiakou City, Hebei Province, 075000 China 2Zhangjiakou Vocational and Technical college, Zhangjiakou City, Hebei Province, 075000 China Keywords: Online course; Systems development; Software environment Abstract.
Network is the current education curricula and research needs of the development Online course is an important part of digital resources, construction of online course is a systems engineering.
For the construction of the current network status, courses should be constantly updated on ideas and development management, our concepts, and fully based on the teaching of science and advanced design concepts to guide the design of our Web-based course work, in order to develop in line with current educational needs of the community Online Course [1].
Curricula and research network can contribute to implementation of the online courses The so-called complete and excellent online courses, in addition to showing the structure of the network environment, the knowledge of the content, the more important to be able to give full play to the network real-time interaction, resource sharing and other features, on this basis, but also real-time Q & A, real-time lectures, learning forums, collaborative problem solving and exploratory design and implementation of teaching activities.
Courses in the network system design also be used SQL SERVER database GUID (Global unique identifier) globally unique identifier as the key fields of table data type which has the following advantages [4]: l First, add data, unique identifier column by New IDO function in advance that the newly added row ID, follow-up treatment for the application to provide a great convenience; l The second is to facilitate the database migration, because the other database does not necessarily have an IDENTITY column, and Guide columns as character columns convert to other databases, both resulting from the application GUID value stored in the database, it can not make any impact on original data; l The third is to facilitate the database initialization, if the application to load some initial data, IDENTITY column handling is more trouble, but you do not need any treatment unique identifier column, directly in T-SQL can be loaded.

For the intake stroke, the CA from the high pressure tank flows into the cylinder quickly, but the valve opening needs a little time, therefore the intake valve requires a small intake advance angle.
For keeping the stable torque, the intake advance angle will change continually.
In order to exhaust completely, not only we augment the valve opening area, but also we need an advance angle for the exhaust valve.

However, it also presents a number of problems: it is difficult to supply the machining fluid to the cutting point and loading occurs easily; the depth of cut is shallow, the length of cut is long, and the cutting edges tend to dull; the dynamic pressure of the machining fluid causes the workpiece to float, and in cases of low machining pressure, machining does not advance; and the workpiece is often scratched.
At a constant machining pressure, the finished surface roughness is not independent of the total amount of material removed, the machining efficiency dropped when the finished surface roughness dropped below a certain value, and machining no longer advanced.

As time progressed and with the technological advances, the computers became powerful contrivances and today they are an integral part of our day-to-day life.
Specialized systems are built to perform dedicated tasks such as a class teacher, a librarian, an aircraft pilot, a mining engineer, and numerous other specialized tasks.
The challenge to the computer technology, science, and engineering is in handling these functions efficiently; and the key to doing so is in understanding the nature of the information that is being perceived, stored, processed, and presented.
