(49.2%) of them thought that the objectives of bilingual teaching should keep up with the international community,(20.6%) thought that bilingual teaching was something like following the suit,and(70.9%) were worried that it might make specialized courses more difficult to study.
As S7-300/400 series PLC(Programmable Logic Controller) is node controller based on field bus net,it is difficult to develop the communication software on Lab Windows/CVI platform for its privacy of communication protocol.
This model's basic thought is to set parameters of this combination forecast model by the learning ability of genetic algorithm to decrease the difficulties of constructing nonlinear combination forecast function.
Results The degree of difficulty reached the idealvalues (the value for city being 0.62, 0.58 for rural area); the different degree was very good (rpb > 0.195, P < 0.05),80% of the testing questions had a distinguishing index D > 0.2, the reliability was very high(correlation coefficientrtt= 0.91), and the validity was ideal.
In 3m-order,4m-order,5m-order and 7m-order bimagic squares,the maximal structural degree of difficulty is 3m order bimagic square. By making use of the placement of magic squares and the known bimagic square composition,SU Maoting and GAO Zhiyuan have successfully structured 30-order,33-order,39-order,42-order,51-order,54-order,57-order bimagic squares.
The change of the rural economic system has greatly increased the degree of difficulty of extension of agricultural scientific and technical result ,and new popularization system and mode are urgently needed.
The average marks from the degree of difficulty and the technique by our male trampolinist are lower than 2.5 and 2.14 point comparing with the world level, and our female trampolinist are lower than 2.85 and 3.12 points.
Our proofs proceed in the time domain and allow us to represent each solution regardless of the spectral radius of P(0):=2-s∑cα, which has been a difficulty in previous investigations of this nature.
It in fact not only reduces the possibility of difficulty arising from degeneracy, but also has the same advantages as pivot method in warm-start to resolve linear programming problems.
The PML technique is used to deal with the difficulty on truncating the unbounded domain while the DSC algorithm is utilized for the spatial discretization.
To circumvent this difficulty, this paper presents a novel hybrid numerical technique of combined difference and spectrum for time-domain Maxwell's equations.
A nonlinear proportion integration differentiation (PID) controller is proposed on the basis of recurrent neural networks, due to the difficulty of tuning the parameters of conventional PID controller.
The simple method used to characterize these fragments led to powerful tools for recognizing genomes which reconcile the section organization of the genus and the degree of difficulty in crossing perennial and annual forms.
By this test method each panel member is given a value which takes into consideration the degree of difficulty of each individual test.
The observed plastic changes appeared to be related to the degree of difficulty in the motor task, and may be of relevance for rehabilitation of gait disorders.
Close cooperation between general surgical departments and centers for vascular surgery allow optimal and differentiated treatment of each case according to the degree of difficulty.
Four examples are included, with growing complexity and degree of difficulty.
