As the filtrate from the treatment of samples of many organo-mineral compound fertilizers has a very dark color (nearly black) , it is impossible to decolor with a little activated carbon, resulting in difficulty in judging the end point during the determination of the chlorine ion content, and sometimes even in impossibility of judgment.
The results show that the ground state of HeNa is unstable , the state 2Π3p has a shallow potential well as well as the state 1Π2p of HeNa+ and the states of 3∑3s and 1∑3s of the cation have very deep potential wells.
As the father of the American pragmatism William James (1842 -1910) has very deep religion feelings which relates to his growth environment on the one hand and social historical reality of U.S.A.
It was very difficult to gather qualified seismic data in the desert area where the desert is thick(100—200 meters)and loose,and where water table is very deep(100—200 meters).
Even in case of very deep and critical color shades, medium fast dyestuffs or poorly soaped/rinsed dyeings, the aftertreatment with Zetesal 2000 or CPW by Zschimmer & Schwarz leads to a marked improvement of the wash fastness.
Our calculated results indicate that both the ground states of MgHe+ 2Σ4s and BeHe+ 2Σ3s have very shallow potential veils, The excited state 2Σ3s of MgHe+ is unstable, the excited states 2Ⅱ3p, 2Σ3s of MgHe+ and 2Ⅱ2P, 2△3d of BeHe+ have deep potential wells.
After observing, the leaves of the numbers of autotetraploid stomatal per unit area are low (about 18~42mm~(-2), but the volume of stomatal was big (length, 13. 375~23. 375μm, width 7. 875~28. 875μm), and the leaves of autotetraploid had obvously feature of C_4 plants.
The research result shows that: Standard Gibbs function of reaction per unit molarΔrGmθincreases gradually and reaction equilibrium constant Kθdecreases gradually with rising reaction temperature, respectively, which explains that the rise of reaction temperature is not available for positive reaction, but in 25~200℃,ΔrGmθ< 0,2.72×1013
The tetragonal fluorite-type phase, which exists in the pressure range between about 90 and 180 kbar at toom temperature, is slightly transparent with very dark red or brown colour, and the cubic fluorite-type phase is dark red and transparent.
Thus, the necessary anatomical arrangement is present for binocular vision.4.The eyes ofPeriplaneta are a very dark, uniform colour, and apparently lack pseudopupils.
The data obtained from autoradiographic study are discussed in relation to the hypothesis that the light cells are elements in active steroido-synthesis, the dark cells are resting elements, and the very dark cells are elements in degeneration.
As process technology scales down to very deep sub-micron (VDSM) in semiconductor manufacturing technology, intrinsic size becomes close to or even shorter than the wavelength used for optical lithography.
Hemoclips may be preferable for very deep ulcers and large visible blood vessels if coaptive coagulation is anticipated to have a high risk of perforation or bleeding.
During the course of this study, the sixth instar larvae of Leucania separata (Walker)were used as the matertal to test the toxicity of cantharidin. Some histopathologicalinvestigations have been made on the blood, mid-gut, thoracic ganglia, fat-bodies, Mal-pigian tubes and testis. Normal and poisoned sections were placed side by side on thesame microscopical slide. Sections for general observations were stained with Heiden-hain's iron hematoxylin and eosin, silver nitrate, gold chloride, or gentian violet;...
As a result of the past few years' investigation, the fishes of Chinese Cyprininae, as known at present, amount to 5 genera and 23 species, of which a new species is herewith described as follows.Cyprinus acutidorsalis Wang, sp. nov. (Fig. 1)Holotype, 65-1821, body length 324 mm. to base of caudal, collected from Lecheng, Qionghai District, Hainan Isl., on March 6-9, 1966, and kept in Xiamen Fisheries College, Fujian Province. 11 paratypes mainly collected from various localities of Hainan Isl. during Nov.,...
