I have engaged in the research of rice stripe blight control for many years in Shanghai farm and found some problems: though there were some reports of research on rice stripe blight resistance, strategy of prevention and cure for the disease has been face to farmer mainly, while geographical location, cultivars and cultivation system adopted on the Farm all affect the effect of control. On the other hand, our Farm has paid attention to the chemical prevention and cure for rice stripe blight and ignored other measures. As for the chemical prevention and cure, phenomenon of drug-resistance and bad effect of prevention and cure existed usually.

本人在上海农场多年从事该课题研究过程中发现的问题：目前对水稻条纹叶枯病研究的报道较多，在防治对策上主要是针对农户，缺乏关于农场地域因素、品种、栽培制度等因素对水稻条纹叶枯病发生及防治的影响的报道；在水稻条纹叶枯病的防治上，农场仍是以化学防治为主，对其他防治措施还不够重视；在化学防治过程中，存在抗药性、防效不佳等问题。

The development of non-formaldehyde dye fixative agent s and their classification by chemical structure were retrospected.

回顾了无醛固色剂发展至今的化学结构类型，探讨了研究开发新品种的思路、固色途径、染色牢度与化学结构的关系以及固色剂 E的特征与应用。

The combustion events in the swirl chamber and the main chamber are processed differently. The combustion in the swirl chamber is broken into three phases: low temperature ignition, high temperature premixed combustion and flamelet diffusion combustion, while the combustion in the main chamber is only considered as flamelet diffusion combustion. The Shell ignition model, global Arrhenius equation and coherent flamelet model are used to describe low temperature ignition kinetics, high temperature premixed kinetics combustion and flamelet diffusion combustion respectively.

把涡流室式柴油机不同区域与不同时期的燃烧过程分开处理，将涡流室中的燃烧过程划分为三个性质不同但相互重叠的阶段：用Shell着火模型模拟的低温着火化学动力学反应阶段，用Arrhenius方程模拟的高温预混燃烧化学动力学反应阶段和用相关火焰微元模型模拟的扩散燃烧阶段，认为主燃烧室的燃烧只有相关火焰微元的扩散燃烧阶段。

By the same token, if the non-print, original graphics and text is the fog, then in accordance with the normal exposure for plate burning, part of the light energy is the black metal forming fog bank be reached the lefthand PS photoptic layer of light energy could not make the non-verbal-Visual section photoptic of the entire layer photochemical completely, as developed, some of the failed to photochemical photographicsensitive layer in PS version of the surface, forming a so-called indosinian theinterior.
