In this analysis, the single crystal of schiff base has been synthesized and the purity of material has been increased by repeated recrystallization process. Single crystal was grown by adopting the method growing in a slow evaporation solution using ethanol as solvent at room temperature. A new fluorescent molecule based on Schiff base has been synthesised and its binding properties investigated by fluorescence spectroscopy to show that it can selectively bind Cu2+ with fluorescence quenching.
By using mathematical reasoning, this paper demonstrates the economic intervening principle: “Virtual disease is to fill his mother but real disease is to rush down his son” and “ Strong inhibition of the same time, support the weak” based on “Yin Yang Wu Xing” Theory in Traditional Chinese Economics (TCE). We defined generalized relations and generalized reasoning, introduced the concept of steady multilateral systems with two non-compatibility relations, and discussed its energy properties. Later based on the intervening principle of TCE and treated the economic society as a steady multilateral system, it has been proved that the intervening principle above is true. The kernel of this paper is the existence and reasoning of the non-compatibility relations in steady multilateral systems, and it accords with the oriental thinking model.
The study investigated the psychological characteristics of entrepreneurship of 829 college students in Chinaby questionnaire. The psychological characteristics include five aspects: entrepreneurial capacity, entrepreneurial belief, entrepreneurial consciousness, entrepreneurial motivation, and entrepreneurial determination. In the five factors, the entrepreneurial consciousness of college students is the highest, and the other four are almost at the same level. There is significant difference on entrepreneurial belief, consciousness, and motivation in different gender of students. Also there is significant difference on entrepreneurial consciousness in different major students and on entrepreneurial motivation in different degree students. However, the college students only with high entrepreneurial consciousness are not enough to succeed in business. The other four psychological characteristics are not only essential to entrepreneurship, but also necessary to their future professional development. College students should have a lot of preparation and accumulation on the other four psychological characteristics of entrepreneurship, and give much more effort to improve them.
