Based on processing and application test, property of 4F 0.06AC resin blown film affected by processing temperature, blow/expansion ratio, frosting line height and equipment is investigated, and suitable processing conditions for 4F 0.06AC film with high strength and good processing property are found out.

Based on reaction diffusion, taking the ratio of seepage line height to dam′s height as the state variable, a coupled map lattices model is introduced to describe the evolvement of seepage line paralleled to the dam′s axis, and judge its nonlinear dynamic character in this paper.

Four highly nonlinear differetial equations were solved numerically with the aid of the computer, using the Adams and fourth-order Runge-Kutta method. The mathematical model predicts the bubble shape, the profiles of the film thikness and temperature as a function of the distance along the machine axis and these results are influenced by processing conditions (the blow up ratio BUR, the strech ratio DDR, the frost line height FH and the pressure difference across the film △p etc.)

Fluorescence Peak near 700nm on the Reflectance Spectrum of Algae in Water: the Relationship of Fluorescence Line Height with Chlorophyll a Concentration

The fluorescence line height algorithm for retrieval of chlorophyll concentration is put into use with three selected fluorescence bands of 665nm, 680nm and 865nm.

Waistline,hip line,height,body mass,blood pressure and so on were surveyed,and according to waistline and hip line the waist-to-hip ratio was calculated. On the basis of body mase/height2 body mass index (kg/m2) was calculated.

Hemorrhoidopexy Staple Line Height Predicts Return to Work

The amount of the scrolling is based on the current viewport size or an estimate of the current line height.

This is due to the fact that the metallisation line height is lower after the first firing which makes the second print step more accurate.

Planform crest line curvature is related to variations in crest line height and patterns of leeside scour depth.

Li, is the line height of the in-phase low-field peak recorded at gain.

According to the new statistics of Glacier Inventory of China,there are 58,700 km~2 of glacier area in China, of which 49% is concentratedaround the Northwest arid area, 29% in the sources of big rivers on the edgeof Qinghai-xizang plateau.The Glacier Inventory of China has been done in acco-rdance with the river system, thereafter, this text have anew counted the glacierarea in accordance with the mountain range.

The Kunlun mountain having thelargest area of glacier in China, is about 21% of all the glaciers in China. Thenext is the Himalaya mountain and Tianshan mountain. The glaciers in Chinaconcentrate around the highest peaks and become a few glaciation centre. Allthe area of glacier of glaciation centre is 26% of the glaciers in China. Thedistribution of snow line height and glacier type is greatly influenced by therlatitude and the precipitation and the topography condition.

The atmospheric effective is first disscused, such as the path radiance and the absorption of hydrogen oxygen and water vapor in the fluorescence wavelength. Then the possible band combinations for fluorescence remote sensing of ocean chlorophyll a are proposed, and the linear model responsed to the relationship between fluorescence line height (FLH) and band's: center position and width is found, based on the same altitude data of airborne remote sensing. It is obvious from model that the FLH is first...

The atmospheric effective is first disscused, such as the path radiance and the absorption of hydrogen oxygen and water vapor in the fluorescence wavelength. Then the possible band combinations for fluorescence remote sensing of ocean chlorophyll a are proposed, and the linear model responsed to the relationship between fluorescence line height (FLH) and band's: center position and width is found, based on the same altitude data of airborne remote sensing. It is obvious from model that the FLH is first affected by the wavelength width of floures-cence peak band, then the wavelength center position of front base band, and finally the center position of rear base band last.Considering the principle that FLH is least affected by the atmospheric effectives and most related to the chlorphyll a concentration, the judgment function for best band selection, is derived with analysis of the different altitude data.Finally, comparing the FLH computed from the data at 125, 175, 1 625, 3 375 and 6 250 m with 14 kinds of band combinations, two optimum sets of band combinations are selected by the judgment function, which is quite good for fluorescence remote sensing of ocean chlorophyll a.
