Study on Development of the Leaf Structure of Podocarpus macrophyllus var. maki Endl.

The leaf development of Podocarpus macrophyllus var.maki Endl.started from the leaf primordium formed by the cell division in shoot apical meristem.During the leaf development,three resin canals from the inferior part of vascular bundles firstly began to differentiate,then protoxylem in vascular bundles differentiated from adaxial side to abaxial side.Meanwhile,a layer of parenchyma cells from the inferior part of protoderm developed into the sclerenchyma,which played an important role in supporting young leaves.When xylem became mature basically,transfusion tissue,phloem and accessory transfusion tissue began to differentiate,so mesophyll tissue finally differentiated into developmental palisade cells and sponge cells.The thicker cuticle was formed in the lateral side of epidermal cells at the same time of differentiation and development for the inner structure of leaves.Therefore,the developmental palisade cells and the cuticle in the leaf structure of Podocarpus macrophyllus var.maki Endl.is greatly significant for photosynthesis and transpiration when it grows in arid and cold regions.

Resource allocation optimization of equipment development task based on MOPSO algorithm

Resource allocation for an equipment development task is a complex process owing to the inherent characteristics,such as large amounts of input resources,numerous sub-tasks,complex network structures,and high degrees of uncertainty.This paper presents an investigation into the influence of resource allocation on the duration and cost of sub-tasks.Mathematical models are constructed for the relationships of the resource allocation quantity with the duration and cost of the sub-tasks.By considering the uncertainties,such as fluctuations in the sub-task duration and cost,rework iterations,and random overlaps,the tasks are simulated for various resource allocation schemes.The shortest duration and the minimum cost of the development task are first formulated as the objective function.Based on a multi-objective particle swarm optimization(MOPSO)algorithm,a multi-objective evolutionary algorithm is constructed to optimize the resource allocation scheme for the development task.Finally,an uninhabited aerial vehicle(UAV)is considered as an example of a development task to test the algorithm,and the optimization results of this method are compared with those based on non-dominated sorting genetic algorithm-II(NSGA-II),non-dominated sorting differential evolution(NSDE)and strength pareto evolutionary algorithm-II(SPEA-II).The proposed method is verified for its scientific approach and effectiveness.The case study shows that the optimization of the resource allocation can greatly aid in shortening the duration of the development task and reducing its cost effectively.

Study on DSM-based task planning of product cooperative development

The results of analyzing the managerial characteristics and complexity of product cooperative development suggest that task planning is an important aspect for process management of product cooperative development and the method for planning tasks should be able to model the dependency between tasks and iterations during the development process. In this paper, a DSM-based method and its corresponding optimization algorithms are developed. At first the coupled task sets and uncoupled task sets are identified, and the tasks are then optimized by the corresponding algorithms. The optimal tasks plan will reduce the development time and cost. Considering the practical requirements in real world, a Multilayer DSM is proposed, and its information communication techniques between DSM and traversing principle are described in details.

Instruction of the Multi-dimensional Developing Perspective on Translation in Translation Competence Development

The overlook of the cultivation of learners’perspective on translation is one of the essential reasons that we fail to enhance learners’translation competence effectively and efficiently.The perspective on translation mirrors not only the interpretation of the essence,value,and function of translation,but the interpretation of culture and intercultural communication,which offers inspiration and implication on translation in the current context.This study analyzes the significance of the multi-dimensional developing perspective on translation and elaborates on the HBARP model to integrate the perspective on translation throughout the learning and teaching process to inspire learners to interpret translation essence and features,to highlight the intercultural communicative significance in the current context with a historical vision.

Task Repetition and the Development of L2 Oral Production

The paper reports the developmental trajectory of Chinese EFL( English as a foreign language) learners’ oral performance in terms of their speech quantity and quality in repeated topic-based tasks. It has been a concerned issue in the theoretical and pedagogical interests that how L2 learners can enhance their oral proficiency. However,as pointed in[22],there are few studies focused particularly on the L2 speakers’ performance change,while more studies are devoted to the performance status. The current research presents a case study of six Chinese students’ English oral development addressing to the issue of learners’ dynamic change. By investigating each speaker’s variation in the speech quantity( the total amount of produced speech) and speech quality( indicated by fluency,accuracy and complexity) during the three-week intervals,we find that task repetition can positively affect the speakers’ oral production.
