The results showed that the main reason of reversal adoption was their dissatisfying with transgenic anti-insect cotton varieties, which were mainly concentrated on singularity and decline of insect-resistance, lower output, and so on.

结果表明，农户对转基因抗虫棉品种不满意是采用逆转的主要原因，不满意的原因主要集中在抗虫性单一且下降、产量低等方面。

Studies from a unitary perspective dissevered the relation between phenomena, and hindered our in-depth understanding.

从单一视角出发探讨复杂的冲动性购买现象不仅割裂了现象之间联系，也阻碍了我们对这个现象的深入理解。

this paper makes the gas remote monitor network as background to do some research on the qos guarantee of the network.qos is a synthesis guide line which can be used to estimate the degree to satisfy with some server,which is a technology to solve the problem of delay and congestion in network.it must integrate multi-qos mechanism to get good qos guarantee in the practical application.three qos models in the ip net application and homologized affective factors are demonstrated.meanwhile,the field of qos protection strategy arrangement in shaanxi coal mine gas network has been picked up as the example.for this situation,the comparison to the different qos models is doing strictly.by combining the tcp congestion control arithmetic with ip congestion control arithmetic,the paper also emphatically describes the corresponded arithmetic model for that.stimulatingly,it is promoted the qos characteristic over-area effectively,which it is based on the original single congestion control.

摘 要：以陕西煤矿瓦斯监测远程联网为背景，研究其联网网络的qos保障策略实现。由于现有的各种qos实现机制无法单独为陕西煤矿瓦斯监测联网网络的qos提供保障，因此在实际应用中必须结合多种机制才能得到较好的qos保障效果。比较了传统ip网络的qos结构体系，通过分析intserv和diffserv两种模型的基本原理、工作方式，并指出其各自的优缺点和网络应用环境，设计了将rsvp协议与diffserv模型相结合来满足瓦斯监测数据传输实时性的要求；针对陕西煤矿瓦斯联网的特性，提出了将tcp拥塞控制算法与ip层拥塞控制算法相结合的算法模型，并且该模型的应用可以在原有单一拥塞控制的基础上有效地提升跨地区网络的qos特性。

Because GM Jewelry Company's product is specialized, higher quality, comparatively higher price, and could be used for boasting; so generally, company's customers have higher requirements for products and are pickier about sales personnel's work behavior.

由于GM珠宝公司经营的商品为高档、单一个体有相对较大价值的炫耀性产品，因而一般来说，公司面对的顾客对商品本身和公司销售人员的工作行为更为挑剔。这决定了GM珠宝公司员工必须更加注重销售的细节。

The clicks may result from sudden tensing of the chordae tendineae or snapping of the prolapsing leaflet.

喀喇音可呈单一或多样性。可出现于收缩期任何时候，但通常会晚于喷射性喀喇音。

With the methods of experimental comparison and mathematical statistics,this paper makes the comparison between Star teaching model and traditional model.The main purpose is to discuss the better teaching model with the comparison,analysis,and induction of statistical data in three tests.The results show that there are more validities and rationality of Star model in the aspects of the effect of study,quantification of teaching,comparative analysis.

经过文献资料的比较和分析，现代定向越野运动无论在技术教学的基本观点上还是在技术的外形和内涵上都有了新的变化和发展，但方法还是比较单一，且大部分采用的是定性分析方法，分析体能、技能的构成、比重时只着眼于整体，一定程度上不够确切，不能细化地作定量描述，因而，学生对技术的分析、认识也必然带有相对的模糊性，不可能从技术的本质上作深入的分析，进而有效地解决问题。

The U 87 Ai condenser microphone is a large diaphragm microphone with three polar patterns and a unique frequency and transient response characteristic.

这个电容mic有着大膜片和三种独立指向性和单一频率还有良好的瞬态响应的特点。

The proposed robust road main direction detection method consists of initial main direction extraction based on the direction histogram of structure tensor and precise direction detection on vectorized edge image. Experiment results demonstrate its robustness and precise. The proposed Gibbs-sampling-based method models road network with marked point process and can effectively extract road network with initial configuration. However it is slow and still can not deal with single and isolated road segment. These problems can be solved by the real-time method. And experiments verify that the real-time method is fast during extracting road segment.

提出的稳健道路局部主方向提取算法以结构张量为基础，通过方向直方图确定大致主方向，并通过矢量化边缘进一步计算准确的方向角，实验结果表明具有良好的稳健性和准确性；提出的基于Gibbs采样的交互式道路网提取方法采用标记点过程对道路网进行建模，在给出初始构造项的情况下，能有效的提取出指定道路网；提出的实时交互式道路段提取算法弥补了上一方法无法处理单一直线道路段和计算过程慢的不足，是上一方法的有益补充，实验结果表明算法能快速提取道路段。

During the information processing, they could produce a singled mental presentation by integrating more information than common fencers.

他们在同时性加工过程中，能整合更多的信息，整合质量较高并形成一个完整的单一表征；而一般运动员的整合能力差，整合质量低。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).
