    • Oil wells are treated with latent acids containing a sulfonyl moiety, wherein the latent acid is capable of providing an active acid after injection into an oil well. The latent acids are converted to active acids such as mineral acids or strong organic acids in the oil well, with resultant dissolution of acid-soluble minerals that impede oil or gas flow. Exemplary latent acids are according to any of formulas (I), (II), and (III) R1YSO2X  (I) R1YSO3−+NHR2R3R4  (II) (R1YSO3)p(OR2)q(NR3R4)rM  (III) In formulas (I), (II), and (III), R1 is selected from the group consisting of C1-C30 hydrocarbyl moieties, C1-C30 hydrocarbyl moieties appended to an oligomeric or polymeric chain, and C1-C30 hydrocarbyl moieties substituted with functional groups containing halogen, oxygen, sulfur, selenium, silicon, tin, lead, nitrogen, phosphorous, antimony, bismuth, aluminum, boron, or metals selected from Groups IA-IIA and IB-VIIIB of the periodic table; X is a halogen or ZCR2R3R4; Y and Z are independently O, S, Se, or NR5, and Y may also be a direct bond; R2, R3, R4 and R5 are independently hydrogen or as defined for R1 and wherein any two or more of R1, R2, R3, R4 and R5 may be interconnected to form one or more cyclic structures; M is a Group IVA metal, a Group IVB metal, a Group IB metal, or a Group IIB metal; and p+q+r=n wherein n is the valence of metal M.
    • 油井用含有磺酰基部分的潜酸处理,其中潜在的酸能够在注入油井后提供活性酸。 潜油酸在油井中转化为活性酸,如无机酸或强有机酸,导致溶于油或气体的酸溶性矿物质溶解。 示例性的潜在酸根据式(I),(II)和(III)中的任何一种式(I)R1YSO2X(I)R1YSO3- + NHR2R3R4(II)(R1YSO3)p(OR2)q(NR3R4)rM(III) I),(II)和(III)中,R 1选自C 1 -C 30烃基部分,连接到低聚或链链上的C 1 -C 30烃基部分和被官能团取代的C 1 -C 30烃基部分 卤素,氧,硫,硒,硅,锡,铅,氮,磷,锑,铋,铝,硼或选自元素周期表的IA-IIA和IB-VIIIB族的金属; X是卤素或ZCR2R3R4; Y和Z独立地为O,S,Se或NR5,Y也可以是直接键; R 2,R 3,R 4和R 5独立地为氢或如对R 1所定义,并且其中R 1,R 2,R 3,R 4和R 5中的任何两个或更多个可以互连以形成一个或多个环状结构; M是IVA族金属,IVB族金属,IB族金属或IIB族金属; 和p + q + r = n,其中n是金属M的化合价。

    • In a multiple processing system or cluster, a pair of processes, assuming the role of a primary process and a backup process to the primary process, are replaced on-line by stopping the backup process; creating the replacement backup process; checking to ensure compatibility between the primary and replacement backup processes so that communication between them is possible and information sent by the primary process to the replacement will be correctly received and handled; providing the replacement backup process with that state of the primary process needed in order to take over the function and operation of the primary process; switching roles so that the replacement backup process now takes over the function and operation of the primary, and the primary becomes the backup; and repeating the steps of creating, checking, providing and switching, to conclude with a newly-installed replacement primary process and a replacement backup process, completing the on-line replacement of the process pair.
    • 在多处理系统或集群中,假设主进程和备份进程作用于主进程的一对进程将通过停止备份进程进行在线替换; 创建替换备份过程; 检查以确保主备份过程和备用备份过程之间的兼容性,以便它们之间的通信成为可能,并且主进程发送到更换的信息将被正确接收和处理; 为替代备份过程提供必要的主流程状态,以便接管主进程的功能和操作; 交换角色,以便替换备份进程现在接管主服务器的功能和操作,主备备份进程备份; 并重复创建,检查,提供和切换的步骤,以新安装的替换主流程和替换备份流程结束,完成流程对的在线替换。
