Porphyridium cruentum were treated with some antibiotics which were used as genetic selected marks in genetic engineering. The results showed that the algae cells could resist high concentration of Penicillin,Streptomycin,Gentamicin and Kanamycin, without any influence at the dose below 100 u/mL of which can kill bacterium adhere to the algae cells . These antibiotics can be used to repress bacterium in purifying algae strain.Porphyridium cruentum is high sensitive to Erythromycin,Terramycin and Ofloxacin....

研究了基因工程中常用抗生素标记对紫球藻的生物学效应，结果表明紫球藻对青霉素、链霉素、庆大霉素以及卡那霉素较不敏感，剂量在100u/mL以下对其生长无显著影响，但能抑制或杀灭伴生的杂菌，因此这些抗生素可用于藻种纯化过程中抑菌；紫球藻对红霉素、氧氟沙星和土霉素非常敏感，低质量浓度就能杀死藻细胞，可用作基因工程或遗传育种的抗药性选择标记；对四环素和氯霉素较为敏感，明显抑制细胞生长，并呈浓度梯度效应。

Every treatment combination has 4 replications.(1)The germination indexes of the former are higher than that of the latter; the germination of the former is stimulated by NaCl density of 0.3 %, while that of the later is restrained by all kinds of NaCl density.(2)With increasing of temperature and PEG indesity,the order of germination rate and vigor of Bromus stamineus and Bromus inermis is decreaced.(3)Under treatment of broadcast sowing and plant density of 549kermels·m~(-2), Bromus stamineus has the highest bud rate, fresh weight, seed yield, while treated with 25cm row spacing and 412kermels·m~(-2) plant densities, tillers, plant height, growth rate increased to the top;(4) Under treatment of broadcast sowing and plant density of 549kermels·m~(-2), its growth rate is took second place, while treated with 15cm row spacing and 824kermels·m~(-2) plant densities, it has the highest seed yield

3撒播时，引进种在播种密度为549粒·m~(-2)处理下单位面积出苗率最高，分蘖数最多，鲜重最大，单株最高，种子产量最大；生长速度在播种密度为412粒·m~(-2)处理下生长最快，密度为549粒·m~(-2)处理下稍次之，结合方差分析可以初步确定它在撒播时的播种密度为549粒·m~(-2)；(4)条播时，在行距为25cm、播种密度为412粒·m~(-2)处理下单位面积分蘖数最多，鲜重最大，单株最高，生长速度最快；种子产量在行距为15cm、播种密度为824粒·m~(-2)处理下最大，在行距为25cm、密度412粒·m~(-2)处理下次之；结合方差分析，就3种规格的行距来说，引进美国无芒雀麦条播时的行距为25cm，播种密度为412粒·m~(-2)；就这两种播种方式来说，应该选择撒播。

In this thesis,We hold the viewpoint of enviroment liability"original sin",which stand for that every act of enviroment has "original sin"that pimpair enviroment,tort of enviroment is aroused by act of enviroment that damnify interests of being attributed.

The silicone rubber membrane used in SRMBR is a polymer-made non-porous material. It is hydrophobe and non-permeable to inorganic salt, and has the high selective ethanol permeability. Compared to the conditional separation technology, the pervaporation through SRM has the advantages of low-cost and low-pollution, especially applicable to separating volatile matter from organic matter-water system or organic-organic matter system.

其中的硅橡胶膜作为一种均相聚合物材料无孔膜，具有不透无机盐成分、疏水和对乙醇有较高选择透过性等特点；与传统分离技术相比，硅橡胶膜的渗透蒸发分离过程具有低能耗、污染少等优点，尤其适用于在有机物-水或有机物-有机物体系中分离挥发性有机物组分，现已用于发酵下游产物分离处理的试验研究中，并取得初步成效。

It is to think network advertisement at or surpass traditional advertisement, cheap Mo place does not go to charge; 2 it is Shu of one-sided pursuit impression, impressional Shu is one of levels that measure network advertisement effect, but sometimes one Ge visits Ke Zai a website can produce ten Ge even Shu of two Ge impression; San is to feel integrated big website is straighter than hanging down effect of advertisement of site of is good, but accept the product ad with apparent feature of numerous target group to great majority, this kind of choice is unwise.

一是以为网络广告等于或胜过传统广告，费用低廉无所不到；二是片面追求印象数，印象数是衡量网络广告效果的标准之一，但有时一个访客在一家网站就可以产生十几个甚至二十几个印象数；三是以为综合大网站比垂直站点广告效果好，但对于大多数受众目标群体特征明显的产品广告，这种选择是不明智的。
