Effects of DPC on Agronomic Traits and Economic Characters of Machine-Harvested Cotton in the Yellow River Valley of China and Chemical Control Techniques

[Objective] The aim was to investigate the effects of DPC chemical controlling technique on agronomic traits, yield and quality of machine-harvested cotton in the Yellow River Valley of China, and clarify the reasonable control period and the application amount of DPC. [Method] The new machine-harvested cotton variety Hengmian HD008 was used as the test material, and 3 different DPC treatments were set. [Result] DPC significantly reduced plant height and branch length, reduced branch angle and leaf area, so the rational control can effectively shape the ideal plant type of machine-harvested cotton. DPC had significant effects on yield and yield components, and the proper amount of DPC could increase the number of bolls during hot days, the number bolls in autumn and the total number of bolls. It increased the boll weight and seed index, but decreased lint percentage decreased, and proper amount of DPC could increase the yield. DPC significantly increased the specific breaking strength of fibers, and proper control could improve the uniformity of fibers, but other indexes had no significant influence. [Conclusion] According to the requirements of machine harvest to the agronomic traits of cotton and the growth characteristics of cotton plant, chemical control could begin after floral bud emergence in cotton about every 10 d, and the spraying amount can be controlled according to the growth amount of the main stem. The daily growth amount of plant height should be controlled at 1.5-1.8 cm, and the plant height should be within 75-90 cm.

The Impact of the Techniques and Tactics Appropriate by the Athletes in Phase Triple Jump and Their Relationships with the Finale Results

The purposes of this study were to describe and compare the techniques used by elite world triple jumper and the Algerian elite team to determine the impact of distribution modality phases allowing the elite to exceeds 17-meter. Our subjects were two world elite 2009 and two Algerian national elite 2013. In the lack of new technology Modem measuring instruments kinematics or kinetics, our study based in measure of the Phase distribution ratio as measure of Stride length Jump distance. That literature review two schools, the Russian technique （which emphasizes the hop phase） and the Polish technique （which emphasizes the jump phase）. Our aims for this study are： Are there any statistically significant differences between the results of the samples in the distance achieved？ Are there any statistically significant differences between practical Ratio relative distances （world 2009-national 2013）？ Are there any statistically significant differences between Stride length phase distances （world 2009-national 2013）？ For that, we have chosen the analysis of variance and correlation of the distances achieved in each of the phases with the official distance of jumper and ＂T＂ student to compare implementation distribution of phases （hop, step and jump） with the results accuses. Based on the practices and weaknesses of elites in practice, we confirm： （1） All the samples practice the Russian technique as model in the distribution of the phase ratio; （2） The problem of our elites is in the hop phase distribution and its relationship with other phases; （3） Improve achieve horizontal vertical velocity in hop phase as solution.

On Techniques and Coping Tactics of Liaison Interpreting

Liaison Interpreting is a type of interpreting performed in two language directions by the same interpreter.Compared with other forms of interpreting,liaison interpreting can be undertaken in various circumstances.And it has no demand for special equipment;therefore it can be taken at any time and at any place.On this account,on-campus interpreters or newly-graduated interpreters will have more chances to receive more tasks of liaison interpreting.During the interpreting process,they may encounter a lot of problems because of a lack of experience or a lack of proper skills.Through this paper,the author hopes to summarize possi-ble difficulties which will happen during liaison interpreting and provide possible coping tactics.The author hopes that this paper can provide some references to green-hand interpreters.

博弈论视角下职业网球竞赛特征探析

文章运用文献资料法、内容分析法、逻辑推理法等研究方法,以博弈论为研究视角,对职业网球的竞赛特征进行系统分析与探讨。认为:职业网球比赛是兼顾静态与动态性质的重复零和博弈;回合前期倾向于非完美信息而回合后期倾向完美信息博弈状态;博弈过程受共同知识和相对知识交互影响,随对手之间熟悉程度的加深存在相对知识向共同知识过度的倾向;受竞技水平和知识影响,竞赛双方策略空间呈差异化特征;对手之间策略的相互牵制性使比赛倾向于纳什均衡;为力争获胜,任何各方均遵循最大最小化原则;策略偏好、风格与打法的交互作用共同形成球员的声誉效应;尽管理性同收益呈非线性关系,但竞赛双方仍以序贯理性为策略对抗的前提。

世界优秀男子网球运动员不同击球区域效用分析——以德约科维奇与费德勒为例

网球属于隔网对抗类项目,运动员的技战术运用是获胜的关键。目前对小球类运动员的技、战术效能的分析与评价主要是以二维平面上的击球作为观察指标。本文运用录像观察法、数理统计法等研究方法,以世界优秀网球运动员的击球位置作为研究的突破口,以前人对网球场击球区域划分为基础,将运动员在不同击球区域中的技术选择与落点选择作为个人偏好,以击球效果为客观收益值,通过构建相对客观、真实的二维空间效用函数来量化世界优秀网球男子单打运动员德约科维奇和费德勒在不同击球区域中的决策与效果。结果表明,(1)德约科维奇在发球局与接发球局效用值均高于费德勒,各击球区域技战术搭配较费德勒更合理;(2)在技术使用上,双方均主要使用正、反手抽球技术,德约科维奇正、反手抽球技术比例比较均衡,费德勒正手抽球技术使用率远高于反手抽球技术使用率;(3)2人的正手抽球技术较反手抽球技术更容易实现战术意图,反手切削球技术难实现战术意图。
