In this paper,the basic thinking and basic principles of quantum teleportation brought up by Bennett et al are reviewed at first,and then one of the basilic steps in quantum teleportation—preparation of the entangled state is introduced in detail,and some of its experimental realization schemes which are representative traditionally and recently are described.

The field experiment on traffic pollution near open road is conducted.

This paper tests the influence of product-harm crisis and its response process on consumer consideration set using data from two field experiments of typical convenience goods and shopping goods carried out in Shanghai.

And the compound polymer fluid system field test and effect acquired during construction are also introduced.

The field tests in six wells show that this system can effectively solve the unstable well bore during drilling recent brittle shale oration in Jiangsu and has achieved remarkable economic benefits.

The result of the field test shows that this test is successful in technology,the oil production of the well is 4 times as much as that of it before the test;the deformation of casing is local, and the result of the strength calculation shows that the deformation will not destroy casing.

In situ experimental study on rat injuries induced by liquid push substance;

In this article,the study of mining method and relevant in situ experiment including experimental contents,object,steps etc are introduced briefly for the purpose of promoting the study of mining method of rock gold mine,of which the mining conditions are comparatively complicated.
