Objective To develop an in vitro culture system for Cryptosporidium parvum in Madin-Darby canine kidney ( MDCK) cell and observe its life cycle ( from desquamate to oocyst). 目的建立微小隐孢子虫体外感染犬肾细胞(MDCK细胞)模型,并观察其生长发育过程。
Edge Detection for Chest Hydrocele Desquamate Cell Based on Combining of Canny Algorithm and Morphology 基于Canny算子与数学形态学结合法对胸水脱落细胞边缘的提取
No bubble, wrinkle or desquamate. 不起泡,不起皱褶或者脱层。
While above 600 ℃, the plating will lose its application properties due to desquamate. 当温度超过600℃时,由于膜层产生剥落而失去使用性能。
Results showed the type of ceramic layer's wears failure was affected by ceramic layer's thickness under this friction condition; while the ceramic layer would desquamate if its thickness was less than the critical numerical value. 结果显示:在滚动摩擦条件下,陶瓷层失效形式受到其厚度的影响,当陶瓷层厚度小于临界厚度时,试样表面出现陶瓷层剥落现象。
But under the dry condition the high frequency alternating heat stress is light, the coat desquamate slowly though a great deal little chap units is formed, the wearing performance of the TiN coat cutter is very good, the steady cutting time is long. 与此相反,干式切削时,高频交变热应力较小,虽在涂层表面有微裂纹产生,但涂层不易剥落,刀具耐磨性较好,可进行长时间稳定切削。
On the condition of SRV wear, The predomination wear mechanisms of the products translate gradually from oxidation and abrasive wears to adhesion and desquamate with the increase of doped ZrC content. 在微动磨损条件下,随着掺杂ZrC数量的增加,合成产物的主要磨损机制由粘着磨损、剥层磨损、氧化磨损和磨粒磨损逐渐转化为以剥层磨损和粘着磨损为主。
There are some quality common faults in dwelling house engineering, such as sugaring, desquamate, empty and tympanic, and crack, which can seriously affect the impressions and usage effect of dwelling house. 在住宅工程中,水泥砂浆地面起砂、脱皮、空鼓、裂缝等现象大量存在,严重影响住宅的观感和使用效果被视为质量通病。
There were the desquamate symptoms in the back of new-born rats in suramin and s+ r groups and the opisthotonos in suramin and s+ r groups with different degrees. suramin组和suramin+raFGF组幼鼠背部有皮屑现象,出现不同程度的角弓反张症状。
Methods A high speed vibration method using a fragment of glass was created to desquamate the flagellin of S. typhi, it could increase the yield of flagellin antigen. By two centrifuging steps, bacterial debris was removed, and the flagellin was collected. 方法:创用玻璃渣高速振动法打脱细菌鞭毛,可提高鞭毛抗原得率,然后分二步离心去掉细菌,再收集鞭毛。
As a result, with water solubility cooling fluid the high frequency alternating heat stress is heavy, the coat desquamate quickly, the wear performance of TiN coat cutter is bad, so it is not adapt to the requirement of machining. 结果表明,在水溶性冷却液浇注冷却条件下,高频交变热应力较大。涂层剥落较快,TiN涂层刀具的耐磨性较差,不能适应切削加工的要求。
At 90(°) jet angles, the coatings present the fatigue desquamate due to the upright wallop of particles on the coating surface. 在90(°)冲蚀磨损时,涂层的失效主要是垂直表面的磨粒冲击力导致涂层疲劳剥落。
The phenomena and mechanism of desquamate are defined for the first time. 首次提出了竹材切削过程表面剥落现象及机理。
The desquamate disappears with the increase of the moisture content but spiny hair appears on the surface if the moisture content is too high. 随着含水率的增加,表面剥落现象消失,但含水率过高,切削表面出现拉毛现象。
Cytology observation on rooting culture of test-tube plantlet: the roots from the callus desquamate easier and the survival rate of transplant is lower because the conducting tissue did not connect with each other. 试管苗生根细胞学观察:由愈伤组织生出的根,由于输导组织的不相连,很容易脱落且移栽成活几率低。
