Skillful Use of Imagery in Two Odes to Spring——Comment on The Soote Season and Spring,the Sueet Spring

The Soote Season and Spring,the sweet Spring are two lyrics that sing the praise of spring.The common feature of the two lyrics is that the two poets depict a series of pictures of the sweet spring by rich and varied imagery for readers.When these pictures are presented to readers,readers feel as if they are participating in them,and the enchanting beauty of spring makes readers feel intoxicated with happiness.The two poets express their different feelings toward nature.     

Removal of cyclops in pre-oxidizing cooperation water treatment process

Zooplankton cyclops propagates profusely in waterbody, cannot be effectively inactivated by conventional disinfec- tion process, and becomes a troublesome drinking water treatment problem. In this work, the qualitative and quantitative ex- perimental studies were carried out on inactivation of zooplankton cyclops using oxidants, such as chlorine (Cl2), chlorine dioxide (ClO2), ozone (O3), hydrogen peroxide (H2O2), ozone/hydrogen peroxide (O3/H2O2), chloramines (Cl2-NH3) and potassium permanganate (KMnO4). The influences of various factors include different oxidant dosages, organic substance contents and pH values. The results showed that currently available oxidants used all might inactivate cyclops in some extent. According to the experimental results, chlorine dioxide, ozone, ozone/hydrogen peroxide and chloramines can be selected as effective oxidants for inactivating cyclops because of their strong inactivation abilities. Then the synergic removal effects on cyclops with ozone, ozone/hydrogen peroxide pre-oxidation followed by conventional water treatment processes were investigated. The results showed that ozone and ozone/hydrogen peroxide pre-oxidation can inactivate cyclops effectively, which then can be removed thoroughly by conventional water treatment processes. Cyclops cannot appear in water after filtration with 1.65 mg/L of ozone and 6 mg/L of hydrogen peroxide, with the inactivation rate being 62% before conventional water treatment processes. Cyclops cannot appear in water after filtration with 1.8 mg/L of ozone, with the inactivation rate being 50% before conventional water treatment processes. For different oxidants, when removal rate was the best, the inactivation rate was not the same. These results may pro- vide reference and model for actual waterworks.

How to set the language context

A.Use all kinds of teaching aids In the classroom,students should be provided with a chance to experience the language in meaningful ways and try out their skills,so the teachers should try to use all kinds of teaching aids to set the language context for the students.And we should not only be acquainted with the use of flash cards and wall pictures,but also we need to learn to collect and make visual aids,such as pictures from magazines,used objects like can and boxes,flannel board,and stick-figures.So with a piece of chalk,objects,people,animals,settings are created on the blackboard and the students'interest and attention are aroused.

Testing results analysis of contact materials’electrical contact performance

Because of the different ways in which contact materials work, the basic requirements for silver metal oxide contact materials are different. They are anti-welded and anti-erosion when closed, anti-erosion when broken, and arc easily moved and have smaller contact resistance. In this paper, La2O3 is used as a stable oxide in contact material to replace CdO. A new type of Ag/SnO2-La2O3-Bi2O3 contact material is first obtained through using powder metallurgical method. Then electrical contact material parameter tester is used to test the electrical contact performance of the contact material. Through experiments, the arcing voltage and current curves, arcing energy curves, fusion power curves while broken and contact resistance while closed were obtained. Analysis of the results showed that the addition of La2O3 makes the contact material have the following advantages: smaller electrical wear, smaller arc energy, smaller contact resistance and arc is more easily extinguished.
