摘要： Continuous processing methods for making absorbable polymeric dry spun non-wovens with one or more of the following properties: high burst strength, fine fibers of average diameter from 0.01 μm to 50 μm, and thickness from 10 μm to 10 mm, have been developed. Improved fiber cohesion is made possible by controlling the tackiness of the fibers of the non-woven during web collection. The polymer is preferably a polyhydroxyalkanoate, more preferably, a 4-hydroxybutyrate polymer or copolymer. A non-woven of poly-4-hydroxybutyrate is most preferred. The non-wovens have fine fibers with average diameters ranging from 0.01 μm to 50 μm, and are derived by dry spun processing, during which a solution of polymer(s) is injected into a stream of high velocity air with a pressure of 1 to 500 psi for solvent stripping and polymer strand attenuation. The non-wovens can be used for a variety of purposes including fabrication of medical devices.

摘要： Embodiments of the present disclosure provide a channel changing method, apparatus, and system. A network side device records in real time a timestamp of a media packet of a multicast media stream which enters a buffer, and a key frame which enters the buffer; when a terminal's channel changing request has been detected, obtains a first timestamp of a media packet which enters the buffer at a channel changing request moment, and a second timestamp of a media packet in which a key frame which is of the target channel and is the last to enter the buffer is located in the media packet; determines a timestamp difference between the first timestamp and the second timestamp; and transmits the timestamp difference and a burst media stream of the target channel to the terminal. In the embodiments of the present disclosure, a delay in playing the multicast media stream by the terminal is reduced.

摘要： An electrical connector (1) includes a dielectric housing (10), a plurality of terminals (13) received in the housing, and a retention mechanism (12) pivotally attached to the housing. The housing defines a plurality of terminal-passages (108) and first mating members (103). Each of terminals includes a bent portion (134). The retention mechanism has an elongate stopper member (120). A pair of cantilevers (122) depends from the stopper member. A second mating member (1222) is formed on each of the cantilevers, for engaging one of the first mating members. Thus the stopper member is rotatable between a first position in which the stopper is protected from thermal warp or deformation, and a second position in which the terminals are secured in the corresponding terminal-passages.

摘要： A low pressure drop structured packing sheet with diversion windows, which are formed on both crests and troughs. When in the expanded state where the diversion window and packing sheet are flat on the same plane, the diversion window has an opening and a fan-shaped portion, with the area of the opening being 0%-1000% of that of the fan-shaped portion. Two side intersection lines between the fan-shaped portion and packing sheet is symmetrical with respect to a central folding line which divides the fan-shaped portion into a left part and a right part. The two side intersection lines intercept to each other with an angel of about 10°-170°. When in the operating state where the diversion window and packing sheet are partially folded towards opposite directions, the fluid at the trough flows to a crest of the other side of the packing sheet with the help of diversion windows, thus increasing the area of vapor-liquid mass transfer. Additionally, when liquid goes across the diversion window, liquid at the bottom of the layer flow becomes the liquid on the liquid film, hence effectively facilitating update of the liquid film and turbulence, increasing mixture between the liquid and vapor, and improving rate of the mass transfer between vapor and liquid.
摘要翻译：一个具有转向窗口的低压降结构包装板，它们形成在两个波峰和槽顶上。当分流窗和包装纸在同一平面上处于展开状态时，分流窗具有开口和扇形部分，开口面积为扇形面积的0％-1000％形状部分。扇形部分和包装片之间的两个侧面交叉线相对于将扇形部分分成左侧部分和右侧部分的中心折叠线对称。两侧交叉线以大约10°-170°的天使相互拦截。当在转向窗和包装纸部分向相反方向折叠的操作状态下，槽的流体借助于转向窗口流到包装纸的另一侧的顶部，从而增加了蒸汽 - 液体传质。另外，当液体流过分流窗时，层流底部的液体变成液膜上的液体，因此有效地促进了液膜的更新和湍流，增加了液体和蒸气之间的混合，提高了液体和蒸汽之间的混合比蒸汽和液体之间的传质。
