While urinate the detrusor has the bladder contracted, inter and outer sphincters relax, the urine is released from the bladder, while ejaculate the amyofibre of prostate is contracted as well as the urethra inner sphincter is contracted to close the bladder neck and the outer sphincter opened, the semen is ejaculated outside. if the regulation is out of control, the inner sphincter wouldn t colse the bladder neck, instead the outer sphinecter is opened to close the door for the semen ejection, as result the semen only flows backward into the bladder, this is called " reversed ejaculation ". because the semen could not be ejaculated into vagina, the fecundation and bearing doesn t occur
當排尿時,逼尿肌收縮膀胱,內外括約肌放鬆,尿被排出體外射精時,前列腺肌纖維收縮的同時,尿道括約肌也收縮,關閉膀胱頸部,而外括約肌開放,精液便射出體外如果調節失控,內括約肌未關閉膀胱開口,而外括約肌反而收縮,關閉了遠端的門戶,結果精液只能倒流入膀胱,這就叫「逆行射精」 ,精液未能射入陰道,也就不能受精生育。Ptfe is one of the most corrosion - resistant materials in the world. however it has defects such as the hot expansion and cold contraction rate is10 times larger than that of steel and the original cold fluidity ( creeping ) etc. therefore, as temperature increases, ptfe extends so excessively that it would collapse and then block the flow of media ; as temperature decreases, ptfe contracts so excessively that it would be ripped and then cause leakage
Ptfe是當今最耐腐蝕的材料之一,可它被製造成襯里的時候,會存在熱脹冷縮比鋼鐵十多倍及固有的冷流性等缺陷,致使ptfe襯里管道、設備,在使用過程中,溫度高時, ptfe襯里層會伸長過多而內癟,阻塞了介質流通;溫度低時, ptfe層會收縮過大被拉裂而泄漏。It has a long history using a throttle device to measure the flow volume of fluid in pipe the method has formed normalization at home and abroad the principle is to make the flow bunch form the particial shrink at the place where the throttle part is located so as to produce a static pressure difference then measure and calculate the flow volume at the moment when the fluid is flowing through the throttle device by the static pressure measured this method is based on the law of conservation of energy and the equation of flow continuity
用節流裝置測量管道中流體流量已歷史悠久,在國內、國際上都已標準化,其原理是使流束在節流件處形成局部收縮,產生靜壓力差,通過測量靜壓力差來衡量流體流過節流裝置時的流量大小,這種測量方法是以能量守恆定律和流動連續性方程為基礎的。After the introduction of the innovations and the improvements of foreign hydraulic shock absorbers, the profound cushion mechanics study is done aiming to the shock absorbers chosen for the thesis ; the cushion process of hydraulic shock absorbers can be divided into several stages, which include local pressure loss caused by across sectional area shrinking, sharp edge throttling and aperture throttling
在對國外新型液壓緩沖器的研究基礎上,針對本課題所選液壓緩沖器的結構特點,提出了分階段建立機理數學模型方法。將液壓緩沖器緩沖過程分為:由於流道斷面突然收縮引起的局部壓力損失階段,緩沖柱塞的邊緣和緩沖孔的邊緣形成銳緣節流階段,當緩沖柱塞進入緩沖孔中形成的縫隙節流階段等三過程。The input video is sampled at the transmitter of the sub - system, and code stream is sent to channel after compression. at the receiver, output video is reconstructed after decompression
在發送端對輸入的視頻信號進行數字採集、壓縮,壓縮后的數據流經通道傳輸至接收端解壓縮,輸出顯示。Better agreements between computation results and experimental data were found using the models. ( 4 ) two phenomena in straight - convergent - divergent - straight microchannels were identified, which are different from the macroflow through experimental studies. one is that the first appearing sonic point position in microchannels is not near throat cross - section
( 4 )對等直收縮擴張等直微管道中氣體流動的實驗研究發現兩個特異現象:其一為微管道內最早出現聲速點的位置不一定在喉部附近,其二為微管道中的臨界壓比與常規值有很大差別。( 2 ) validate whether the crest elevation can meet the require of energy dissipation and erosion prevention during the beginning period of flood discharge. ( 3 ) calculate the altitude of downriver cofferdam, and make it meet the require of energy dissipation and erosion prevention. ( 4 ) calculate some average velocity of flow through some sections, including contracted section in stilling basins behind upriver cofferdam, if the hydraulic jump happen in lower reaches of the river. the program will calculate the average velocity of flow of contracted section and the length of the apron
主要設計內容包括:計算上游圍堰后消力池的尺寸;驗證泄洪初期壩面高程是否能夠滿足消能防沖需要;計算下游圍堰堰頂高程,使其滿足泄洪期圍堰和壩體過流的消能防沖和工程進度的需要;計算部分斷面平均流速,包括:上游圍堰后消力池中收縮斷面的斷面平均流速;壩首和壩末的斷面平均流速;當下遊河道發生水躍時,計算下遊河道的收縮斷面平均流速及需要鋪設護坦的長度。Norepinephrine ( ne ) - evoked contraction was observed in rat aorta by using routine blood vascular perfusion in vitro. the experimental designs were as follows : 1
本課題利用去甲腎上腺素引起的血管收縮模型,通過常規離體血管灌流技術研究了陰離子通道對血管張力的調節及其機制。Finally, the two dimensional flow in the diffuser is calculated, the results show that the change of ma makes an effect to the performance of the diffuser. owing to the accretion of ma, the action of oblique shock waves and the boundary layer pricks up, the flow separates from the wall where the shock waves impinge on the boundary layer more quickly, the cluster of diamond shock waves becomes larger. moreover, by comparing the change of flow field under different structure parameter, it is found that the augment of length of constant area section alter the structure of fluid field little, a smaller area ratio and larger angle of compression section make the diffuser working better
最後,針對擴壓器中的二維流場進行了數值模擬,結果表明馬赫數對擴壓器性能影響較大,隨著馬赫數的增大,擴壓器管道內激波-附面層干擾加劇,流動從附面層分離相應加劇,激波串數目增多;通過比較不同結構參數下的擴壓器內流場,發現等直段長度的變化幾乎沒有改變流場結構,只是對局部流場稍有影響,並且在其它參數不變的情況下,一定范圍內減小面積比a2 / a1和增大收縮角有利於擴壓器性能的提高。Similarly, an outflow of money causes the monetary base to fall along with the loss of foreign reserves through the convertibility undertaking. soon interest rates will rise to a level that makes the return for holding hong kong dollars attractive, thus stemming and reversing the outflow
同一道理,資金外流會令貨幣基礎收縮,而外匯儲備會透過兌換保證的運作而流失,利率隨之上升,投資者受到持有港元的回報吸引,於是資金流入港元,扭轉原來資金外流的情況。Swing check valves can be adversely affected by turbulence if placed too closely to other piping components such as pumps, control valves, meters, reducers, tees, elbows, etc
