A summary is made to the developing history of ancient chinese ceramics from technological point of view ,such as "tang san cai"ware,"blue and white"ware,"gu cai"and "fen cai",and "dou cai".
Through analysis of the causes of the spillage from dredger buckets when feeding the receiving hopper, it is indicated that the spillage losses could be reduced to the minimum taking such measures as changing the bucket opening form, adjusting the pressure and flowrate of flushing water during ore discharging, shortening the relative distance between the bucket chain and receiving hopper, etc.
Based on the analysis of the causes of bucket falling,some relevant improving measures were put forward such as increasing the reliability and service life of the parts of buckets,improving the structure design of buckets. Through the implementation of these measures,the probability of bucket falling has been reduced from 19% to1.8%.
This class of algorithms includes local decomposition algorithms for discrete optimization problems, nonserial dynamic programming algorithms, bucket elimination algorithms, and tree decomposition algorithms.
Global and regional climatology averaged over the last 25 years of 100 year integrations from the IAP GCM with and without IAP94 ("bucket" scheme) is compared.
This paper investigates the hydrological interactions in the atmosphere-evegetation-soil system by using the bucket model and several new simplified intermediately complex models.
In this paper, the incipient separation is first predicted with Dou and Deng (1992)'s theory and then compared with Lu and Settles' (1990) experimental data.
The "Compound Mixture of Two Fairies" has been used clinically for treatment of hypertension. It is composed of Curculigo ensifolio, Epimedium, sp., Morinda officinalis, Phellodendron chinense, Anemarrhena asphodeloides, and Angelica sinensis. In normal dogs, intragastric administrations of 6g (crude drugs) per kg t.i.d, for 20 days produced no toxic reactions: If the dosage was increased 3—4 times, emesis and diarrhea occurred, probably due to alimentary disorder from the bulk of the decoction. When the Co...
1. Changes in some enzymatic activities and content of -SH group of the skin of mice during carcinogenesis induced by methylcholanthrene were investigated.
Cardiac output was determined according to Fick's principle, while renaI blood flow (RBF) and glomerular filtration rate (GFR) were measured from the clearances of PAH and creatinine. One hour after an i.v. injection of guanethidine 5 mg/kg, normal dogs showed a very slight hypotension, which was relatively more noticeable in renal hypertensive dogs. The cardiac output, stroke volume, and ventricular work tended to decrease tn normotensive dogs, but tended to augment in hypertensive dogs. These alterations,...
