有害物

In order to save energy and better control pollutant ,we design a new type of exhaust hood—— air curtain exhaust hood .

为了节能和更好地控制有害物，我们设计了一种新型排风柜———气幕式排风柜，我们对送风口为条缝型送风口的气幕式排风柜进行了理论和实验方面的研究。

This time the small number of blastocyst cells, once affected by the impact of harmful substances, it is difficult to repair cell damage.

这个时候囊胚细胞数量较少，一旦受有害物的影响，细胞损伤则难以修复。

Experts have recognized that the problem can not be thoroughly solved unless traditional way of suction be given up, that is, substituting soft brattice or blast suction air for rigid apron, and extending suction entrance near harmful substance or surrounding it.

国内外有关专家已认识到，要彻底解决这个问题，必须放弃传统的抽吸方式，利用柔性的风幕或吹吸气流代替刚性的挡板或吸气罩，将吸口"沿伸"到有害物附近或干脆将其"罩住"。

The flow characteristic of intake manifold has sensitively influence on engine, including economy performance, dynamical performance and the level of injurant emission.

其流动特性对发动机性能的影响十分敏感，其优劣影响到汽车的经济性、动力性和有害物排放的水平。

Catalyst convertor may effectively reduce harmful exhaust emission, which is broadly used on motor vehicle.

催化转化器可以有效地减少汽车有害物的排放，在汽车上得到广泛的应用。

Established in 2000, this DIY pest control store offers a complete line of professional strength pest control products that will save you 70%-80% off what an exterminator would cost you.

成立于2000年，本自己动手的有害物控制商店供应全套的专业有害物控制产品，可节约70%-80%的成本，投入很少。

SaFety/detonation prevention Leakage Atmospheric diffusion Inflammable and detonable Diffusion concentration

在研究易燃、易爆、有毒的重大危险源和泄漏物扩散模型的基础上，建立了易燃、易爆、有毒物三维数值模拟程序，得到了复杂地形条件下关键点的有害物浓度历史和有害物的时空分布

Board of inquiry chose 18 monitoring point in Beijing high street, undertook in different period of time ill other people detects respectively, as a result discovery is nodded every almost inside heavy traffic period of time, carbon monoxide 、 always volatilizes the harmful thing such as organic matter is great degree all exceed national level.

调查组在北京主要街道选择了18个监测点，分别在不同时段进行了有害物检测，结果发现几乎每个点在交通拥挤时段内，一氧化碳、总挥发有机物等有害物浓度均超过国家标准。

Aiming at the problem that injurant discharged from the traditional fuel ejection system pollutes environment,analyzes the causes that injurant comes into being.

针对传统燃油喷射系统有害物排放污染环境的问题，分析了有害物生成的原因。

The results show that the rotary air curtain exhaust hood can effectively control the deleterious materials,greatly improve the suction.Therefore,it realizes long-distance trapping and low velocity emission of deleter...

结果表明：旋转射流屏蔽作用下的抽吸流场具有中部压力较低和提高抽吸能力的作用；新型旋风气幕式排风罩不仅能有效地控制有害物扩散，而且可以实现远距离捕集有害物及以较小的排风速度排放有害物。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。
