1) Non - point source pollution is one of the most important causes of eutrophication.

2) To calculate average perennial load of non point source pollution, a direct measurement method is developed.

3) When occurs exceptionally, informs in the point source to have the unusual condition the indicating lamp.

4) Including client and server - side source and point source.

5) Functions of fixate point source and model of highway - surface were provided.

6) A practical estimation method of non - point source pollution load - mean concentration method was established.

7) The research and development of urban Non - point source pollution are summarized in this paper.

8) Soil erosion and non - point source pollution are two serious environmental issues.

9) The non - point source pollution caused by agriculture is the main source of today's environmental pollution.

10) Agricultural non - point source pollution is driven by dynamical factors, water character and landform characteristics.

11) Agricultural non - point source pollution had no certain pollution source which had obvious potential, complexity and invisibility.

12) Calculating the environmental damage cost of a single point source is the core of this paper.

13) An alternative explanation is that familial infection is occurring from a point source.

14) One additional device is a spectrometer to study the infrared spectra of strong point sources.

15) Objective To investigate the electrical field distribution in the cylinder volume conductor with point source by means of experiment.

16) SWAT model was used to evaluate agricultural non - point source pollution of Daning River watershed.

17) The method is based on the surface charge method, in which the space charge effects have been considered. A simplification against the structure of point source has been made.

18) A facility has been developed that can function as a low-energy electron point source(LEEPS) microscope or a field-emission microscope(FEM).

19) The one-dimensional Fresnel zone phase correcting principle can be applied in a cylindrical surface to constructed a new type of point source feeding lens antenna.

20) The result indicated that eutrophication would not be induced in Baiguishan Reservoir without point source pollution.

21) Due to intense oscillation of these integral, calculation using direct numerical integral, i. e. , GPSS (the generalized point source synthesis method), is complex.

22) Consider first a light wave spreading out from a point source.

23) In the flourishing southeast region of China, agricultural non - point source pollution is extremely serious.

24) As the technical development basis of new countermeasure principle and devices, the jamming effectiveness test of IR decoy against point source guided missiles was introduced briefly.

25) Fog up a piece of glass with your breath and look through the fogged plate in a darkened room at a white-light point source.

26) When the primary image was reconstructed with a white light point source, a clear, distortionless, highly stereoscopic and orthoscopic quasimonochromatio deep-scene 3-D image was displayed.

27) First, a variational equation is given for the electric field on a 3-D geoelectric section caused by a point source.

28) The specific discharge is infinite at the vicinity of every point source or sink.
