In this paper, the characteristics and safety of bar gene, PAT proteins and glufosinate were expatiated. The bar gene and glufosinate play important roles in plant engineering, and bar sequences are considered to be as safe as any other DNA in food and have no pleiotropism.

本文对除草剂草丁膦及其抗性基因之一－bar基因及其产物PAT蛋白的一些特性和安全性作了阐述。bar基因及筛选剂草丁膦在植物基因工程中发挥着重要作用。bar基因无多效性，与食物中的DNA一样安全。

To improve the efficiency and application, pollen tube growth of different Brassica species is observed and factors of transformation are studied for optimization.

继而通过比较不同白菜型油菜、甘蓝和甘蓝型油菜品种的花粉管生长规律和转化率，得到表达报告基因的除草剂抗性植株，实现了不同类型和基因型油菜的高效转化，扩展了方法的应用范围。

Suitable scope applies to the fireweed such as grass of barnyard grass of rice field prevent and kill off, fescue, pondweed, lustre have diarrhoea, wild arrowhead, Mu Cao, small arrowhead, with the red that kill grass, Ding Cao the herbicide such as amine, He Dazhuang is mixed with, can enlarge the chart that kill grass.

适用范围适用于稻田防除稗草。牛毛草。眼子菜。泽泻。野慈姑。母草。小慈姑等杂草，与杀草丹。丁草胺。禾大壮等除草剂混用，可扩大杀草谱。亦可用于玉米。

D-lactic acid is considered to be a very important chemical compound as a chiral material or intermediate in organic synthesis. D-LA is a prosoma of many chiral compounds with applications not only in the pharmaceutical and cosmetic industry but also in highly efficient and lowly toxic pesticide and herbicide.

D-乳酸是重要的手性中间体与有机合成原料，是多种手性物质的前体，广泛应用于制药、化妆品和高效低毒农药及除草剂等领域的手性合成。

The thesis was designed to optimize the cultures of producing D-LA bySporolactobacillus sp. and analyze the effects on fermentation in order to produceD-LA effectively.D-lactic acid is considered to be a very important chemical compoundas a chiral material or intermediate in organic synthesis. D-LA is a prosoma of manychiral compounds with applications not only in the pharmaceutical and cosmetic industry but alsoin highly efficient and lowly toxic pesticide and herbicide.

本研究的目的是通过对芽孢乳杆菌发酵工艺的研究，建立一条产物光学纯度高、工艺简单，成本较低的D-乳酸生产路线。D-乳酸是重要的手性中间体与有机合成原料，是多种手性物质的前体，广泛应用于制药、化妆品和高效低毒农药及除草剂等领域的手性合成。

It was a proper method to determine seven kinds of three pyridine class weed killers in soil.

该方法是分析土壤中均三氮苯类除草剂农药的一种较为理想的方法。

Our main products include Insecticide, Herbicide, Fungicide, PGR, Rodenticide and Chemical Intermediate.

产品主要包括杀虫剂、除草剂、杀菌剂、植物助长剂、杀鼠剂及化工中间体等。

At that time the company was best known for Roundup, a herbicide popular with farmers.

在当时，公司由于生产草甘膦为人所熟知，草甘膦是一种农户常用的除草剂。

The spraying control system aiming at weed based on machine vision was designed and developed. The index of 2G-R-B is used for segmentation and the method of improved pixel lateral histogram is used for extracting the center of crop row,the method of threthold is also used for identificating between-row weed and BP ANN based on fratal and texture is used for identificating in-row weed. PLC correspondence and performing procedure is desi -gned and developed.

设计和开发了基于机器视觉的麦田除草剂对准喷药控制系统，该系统的视觉子系统首先用过绿的2G-R-B进行植物与土壤背景的分割，其次用改进像素直方图法识别作物中心行，用阈值法识别行间杂草区域，用BP神经网络基于分形和纹理的共同特征识别行内杂草区域，设计并开发了计算机与PLC的通信程序，设计了PLC的运行程序。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
