(1) The expansion method by negative pressure for preparing thin - walled heat shrinkable pipe continuously was detailed.

(2) During the course of sinkage under the negative pressure, the interaction occurs between the structure and the foundation.

(3) Methods Automatic biopsy device with negative pressure under the guidance of ultrasound through an oblique angle were performed in 669 patients with nephropathy.

(4) Recommends the proper value of pressure difference between negative pressure wards and adjacent clean zones.

(5) Objective To evaluate the value of the negative pressure drainage in parotidectomy and analyze the clinical factors correlated with salivary fistula post-parotidectomy.

(6) A vacuum pump creates negative pressure for correct operation of the filtrate recovery system.

(7) The advanced negative pressure absorption system is equipped for feeding sheet. Suction volume adjustable, which makes uneven sheets feed smoothly.

(8) By using the technological process of negative pressure spray absorption, the reclamation and treatment of the sulphur oxide are studied. Thus a feasible way is provided for production.

(9) The "doublesichamber negative pressure method" in a shock tube system for high sound pressure level calibration is provided in this paper.

(10) The velocity change of instantaneous negative pressure wave along the pipeline is analyzed when hot oil is transported. Two searching methods are applied to locate leakage through numerical integral.

(11) Cardiotomy suction negative pressure was determined by vacuo meter during ECC.

(12) On a whole, this kind of negative pressure isolation ward is equipped with simple sanitary equipments, can be foldaway and transported conveniently.

(13) Objective: To explore the chinical value of low negative pressure successive suck drainage(LSSD) for resection of breast carcinoma.

(14) In the pyrogenic production procedure, negative pressure may exit in gas equipment and containers and consequently damage them.

(15) When pump delivers water, there will be negative pressure in the water inlet, which can suck air automatically. After gas-water is mixed by the water pump vane, it flows along the horizon pipe.

(16) Negative pressure air system ensures the higher cleaning rate and improves the operational environment.

(17) Methods: The vacuum negative pressure meter and the delayed control line were used.

(18) Simultaneous changes in the cell walls, hormonally induced, produce negative pressure potentials during extra-cellular freezing, which control the dehydration.

(19) Many scholar have different opinions about clinical relationship between negative pressure tympanogram and middle ear effusion.

(20) Vacuum may be thought of as the absence of pressure. It is the measure of negative pressure between standardized atmospheric pressure and a theoretically perfect vacuum.

(21) Methods: The simple mini-size perfusion cannula for continuous douche and negative pressure drainage was handmade and used on 23 patients suffering from large hypodermal infected lacuna.

(22) In the latter disease, increased effort is required to produce a higher negative pressure in the pleural space to inflate the lungs.

(23) When cut off the water supply, because of the negative pressure in feed pipe, siphonage arises more easily.

(24) The results show that the size and direction of the gas-phase velocity in the standpipe are chiefly affected by the mass flux of solid and negative pressure gradient.

(25) When water is pumped out of a chamber below the plate creating negative pressure, the stretchable sensors are pulled down, producing a concave shape.

(26) The system can automatically fill in fresh air for dehumidify and prevention of negative pressure higher than designed in the cabin when testing. Sentencedict.com

(27) Diseussion about the course during molding and easting of negative pressure dry-sand EPC has been expounded.

(28) Designed with the beginning of indirect horizontal tube cold process, the choice is negative pressure operation, that is, before the blower electric fishing devices.

(29) The data handling to the whole system is taking a decisive factor in the negative pressure wave law leakage checkout system, and can influence the accuracy and the precision of this system.

(30) Objective To discuss the clinical value and existing problems of the fixation technology of negative pressure vacuum bag in tumor precise radiotherapy.
