几种麦田除草剂的混用方法

现在，农民种田已经基本告别了除草、拔草时代，田间除草主要是化控，但是很多人对除草剂施用方法和施用剂量不了解，导致化控效果不理想。其实化学除草只要用量和用法得当，尤其是几种灭草剂配合施用得当，不但省时省力，还节省用药量，降低生产成本，效果相当不错。下面介绍几种小麦生长不同时期麦田除草剂的混用配方：

农药混用的计算方法

农药的混用，须计算各药剂的用量，准确称量配对，才能达到经济有效的施药目的。一、作用对象不同的农药混配，可按下式分别计算。

介绍了化学除草剂使用技术,包括施药时期、施药方法、施药剂量、对环境和田间管理的要求、不同品种和栽培方式下的使用、残留期、混用方法等内容,以期为化学除草剂的使用提供参考。

Design Hybrid Methods for Encoding Prior Knowledge in Feedforward Network with Application in Chemical Engineering

Three-layer feedforward networks have been widely used in modeling chemical engineering processes and prior-knowledge-based methods have been introduced to improve their performances.In this paper,we propose the methodology of designing better prior-knowledge-based hybrid methods by combining the existing ones. Then according to this methodology,two hybrid methods,interpolation-optimization (IO) method and interpolation penalty-function (IPF) method,are designed as examples.Finally,both methods are applied to modeling two cases in chemical engineering to investigate their effectiveness.Simulation results show that the performances of the hybrid methods are better than those of their parents.

Motion Capture for Puppet Control Using Integrated Sensor System

The paper aims to execute puppet without restrictions by controling puppet using robot. We controling puppet in the same way as the present puppet, but we perform this by robot. It offers more advantages and lessen the weak points. It needs various actions and expressions because of the nature of a puppet. The biggest problem which executes this is the ways to create a system. This thesis proposes motion capture of developed method with solution of this problem. So, we create various contents needed by puppet. In this part, developed method means a mixed method on the basis of optical system and magnetic system used mainly for the present method of motion capture. We lessen the weak points of each method and propoe solution of create motion for pupct by offering more advantages. So we solve difficulties of executing puppet and probable probkans when we execute puppet by using robot. The solution of this thesis is proven by applying control of puppet.

Effects of Improving Durability of Concrete by AQUA CURTAIN Curing and Its Application m Development of the New Wet Curing Method

We report a wet curing system developed and made suitable for practical application to curing the interior and verticalconcrete surfaces of tunnel linings after the formwork has been removed. In this system, air is evacuated from the gap between the curing sheet and the concrete surface to create a close contact, and by supplying water to the space between the contacting surfaces, a water film is formed over the concrete surface. This enables the wet curing of vertical concrete surfaces and interior surfaces of tunnel linings after the formwork has been removed, a process that has to date been difficult. In this paper, the effects of wet curing on improving the durability of concrete are verified, and examples of the application of wet curing to actual structures are presented.

Introduction of a Japan Concrete Institute Guideline： Practical Guideline for Investigation, Repair and Strengthening of Cracked Concrete Structures

There are many cracked concrete structures worldwide. Although there have been numerous efforts to eliminate cracks, some cracks are very harmful and should be repaired as soon as possible. On the other hand, some cracks are almost harmless. So, a good guideline regarding how to deal with cracks in concrete structures is needed. In this guideline, the practical investigation, repair and strengthening method of cracked concrete structures is discussed. And the detecting subjects are cracks generated immediately after casting and during the service time. This guideline targets on the owners （including managers） of concrete structure and the engineers working for the maintenance of concrete structure. JCI （Japan Concrete Institute） published first version of ＂Practical Guideline for Investigation and Repair of Cracked Concrete Structures＂ in 1980, and then the fourth version titled ＂Practical Guideline for Investigation, Repair and Strengthening of Cracked Concrete Structures--2009＂ was published. This guideline is very practical when cracks are observed in existing concrete structures, in any other countries as well as in Japan. These three authors led the establishment of this guideline.

A hybrid method for extraction of protein-protein interactions from literature

In this work, a hybrid method is proposed to eliminate the limitations of traditional protein-protein interactions （PPIs） extraction methods, such as pattern learning and machine learning. Each sentence from the biomedical literature containing a protein pair describes a PPI which is predicted by first learning syntax patterns typical of PPIs from training corpus and then using their presence as features, along with bag-of-word features in a maximum entropy model. Tested on the BioCreAtIve corpus, the PPIs extraction method, which achieved a precision rate of 64%, recall rate of 60%, improved the performance in terms of F1 value by 11% compared with the component pure pattern- based and bag-of-word methods. The results on this test set were also compared with other three extraction methods and found to improve the performance remarkably.

Development and evaluation of a novel multiplex probe array for rapid differential identification of Mycobacterium in clinical specimens

Rapid differential identification of Mycobacterium species is essential for effective diagnosis and management of mycobacteriosis. The aim of this study was to develop a novel multiplex probe array based on the 16S-23S rRNA gene internal transcribed spacer sequence for the genotyping of mycobacteria to the species level. A pair of primers and a set of genus- and species-specific probes were designed from the conserved and polymorphic regions of the 16S rRNA gene, internal transcribed spacer, and 23S rRNA gene sequences of mycobacteria. We used a novel multiplex probe array for identification of 266 clinical specimens obtained from patients with mycobaterial infection. The results showed that the overall specificity and sensitivity of our novel probe array were both 100% for the genus-specific probe and Mycobacterium tuberculosis complex- specific probe. There were 79.3 % （23/29） of nontuberculous mycobacteria which could be identified to the species level directly in the specimens from China. Some intraspecies heterogeneity in M. avium, M. intracellulare, M. chelonae and M. abscessus was observed. With the increase of sequences of internal transcribed spacer and numbers of whole microbial genomes, and further optimization of probes, the multiplex probe army will become a promising tool for the rapid and accurate identification of mycobacteria in ordinary clinical laboratories.

Performance evaluation method of hybrid navigation constellations with invalid satellites

The construction of a navigation system plays an important role in the development of national politics,economy and military affairs.Nowadays,the Beidou navigation system is facing a transition period from the regional navigation system to the global one.For the global constellation,the system performance will not be seriously degraded when one or two satellites are invalid,but it is out of case for the regional constellation,which usually has fewer satellites and less redundancy.This paper deals with this problem of hybrid constellations and analyzes the influence of the disabled satellites on the system.With hybrid constellations and simulation methods designed,the influence of invalid satellites on the navigation system is fully investigated.
