收縮中期的
英文
mesosystolic-
The systolic pressure is defined as the peak pressure in the arteries, which occurs near the beginning of the cardiac cycle ; the diastolic pressure is the lowest pressure ( at the resting phase of the cardiac cycle )
心動周期開始時動脈出現的最高值為收縮壓,心動周期靜息期出現的最低壓為舒張壓,心動周期全過程中的平均壓力為平均動脈壓。The expansion agents can only make up the shrinkage to some extent, and the compensation effects would be reduced when the retardener and fly - ash are used. the expansion agents are not panaceas to avoid the shrinkage cracking as expansion can also reduce the concrete soundness. under bad curing condition, the polypropylene fibrillated film fiber can improve concrete ' s anti - crarking property, while the nominal steels have very unobvious effects. to reduce the concrete shrinkage thus avoid the cracking, the former factors must all be taken into account in concrete proportion design to develop sound concrete
研究結果表明,水泥的品種和用量是影響混凝土收縮值的主要因素之一,當混凝土中水泥用量超過470kg / m ~ 3時,混凝土的收縮值超過400 10 ~ ( - 6 ) ,在約束狀態下存在高開裂風險;採用細砂使混凝土單位用水量顯著提高,收縮值也大幅增加;優質粉煤灰總體上能抑制混凝土的收縮,以超量方式摻入其抑制作用更加明顯,但粉煤灰混凝土早期的粘聚性較差,應注意養護,以免失水產生龜裂;早強減水劑和緩凝減水劑都會使混凝土收縮值增加;膨脹劑只能補償混凝土部分收縮,同時受緩凝劑和粉煤灰的抑制,而且膨脹使混凝土的體積安定性增加了不確定因素,膨脹劑不是解決混凝土收縮裂縫的良方。The proportion of plastic shrinkage cracking is rather high in early cracking. the plastic shrinkage cracking would effect construction appearance and promote the propagation of drying shrinkage cracking or other types cracking, but also provide a passage for aggressive agents penetrating and moving to the concrete mass
塑性收縮裂縫在早期裂縫中佔有相當大的比重,其存在不僅影響工程外觀,促使乾燥收縮裂縫或其它形式裂縫的發展,而且還將為侵蝕性介質向混凝土基體滲透、遷移提供通道,對混凝土的耐久性造成嚴重影響。There is an old saying in our field - " no dam is not crackable ". the crack is mainly because of the bad dilation after " alkali - aggregate reaction ", the temperature traverse inside and outside the concrete with the happening of heat evolution and the shrink of volume due to the cooling of concrete
水電行業有句「無壩不裂」的俗話,產生裂縫的原因主要有「堿集料反應」造成的破壞性膨脹,水泥水化過程中放出的熱量出現的混凝土內外溫度梯度和水泥石硬化後由於後期降溫發生的體積收縮等造成。Creep analysis methods of high - rise buildings and large span buildings can only refer to creep coefficient method in bridge engineering or the method of degree of creep in hydraulic construction engineering under the present experiment conditions. in this paper, the incremental expressions of concrete creep and shrinkage strain when the initial computational age is not the same as the loading age are derived and corrected from the concept of concrete creep coefficient and the mean value theorem of integral and the principle of superposition. the differences of efficiency and accuracy of creep analysis between the finite element method with creep coefficient and the initial stress method with degree of creep are presented. this paper suggests that engineers should use the initial stress method with degree of creep to estimate the influences of creep on high - rise buildings and large span buildings on the basis of conceptual design

論文的模型探討了下列因素和中國信貸配給現象之間的聯系:商業銀行對信貸風險的態度變化,在辨別和控制信貸風險上開始投入大量的成本,這一過程會導致信貸配給;商業銀行對與法治環境相關的交易成本和抵押品清償價值的日漸關注會導致信貸配給;宏觀經濟緊縮時期資產價格下降會導致信貸配給;商業銀行經營目標函數偏離利潤最大化,近幾年金融業改革過程使商業銀行目標函數發生變化,這一變化過程可能導致信貸配給;在市場分化的條件下,收益水平低的市場會遭受信貸配給;在經濟下滑時期,商業銀行尤其會對高風險市場配給信貸;利率市場化使商業銀行的存貸利差至少在一段時間內縮窄,利差縮窄可能加重信貸配給的程度:在利率市場化條件下,弱勢借款者,包括中小企業,遭受信貸配給的程度可能得到緩解,但支付的貸款利率水平將會升高。Members also noted that, over the medium term, the specification of a number of concrete measures on both the revenue and expenditure side should help increase the credibility of the governments medium - term consolidation strategy
