1概述我厂拥有32孔二分下喷式焦炉一组,具有年产20万t冶金焦的能力。其配套加煤设施为JZ—10型装煤车,投运几年来发现,装煤斗存在两方面的问题1)装煤斗容易堵塞,造成下煤困难。2)放煤闸板工作不可靠,维修不便。2原因分析原煤斗(见图1)上下各为一锥形斗,另有一外斗套,各部分用螺栓联接,内装一圆弧形闸板(仅画中间斗)。此结构使原煤容易积存在下锥斗和外斗套中,特别是雨季,煤容易粘结,造成经常性堵塞,难以顺利入炉。加煤时,往往使用套筒撞击炉顶,人力敲打下锥斗及斗套,通过冲击来达到下煤的目的。同时,从…  相似文献

研究山东地区高挥发分1/3焦煤放置时间过长后煤质的劣化情况,及其替代河南地区1/3焦煤参与配煤炼焦试验对配煤质量及所得焦炭质量的影响。结果表明,山东地区偏气煤性质的高挥发分1/3焦煤放置时间过长后煤质劣化严重,其参与配煤炼焦对配合煤的挥发分和G值影响明显,随着其配入量的增加,焦炭质量逐渐下降,其最大配入量以不超过6%为宜。  相似文献

These minutes are the official record of the actions of the Association taken during the year by both the Board of Directors (the Board) and the Council of Representatives (Council). The roll of representatives was called at each Council meeting, and more than a quorum answered to their names. Reference is made in these minutes to various reports, some of which will be published elsewhere. Copies of these reports were distributed to Council and are on file in the Central Office. As long as the supply lasts, extra copies of many of the reports are available from the Central Office. These minutes are arranged in topical rather than chronological order, and subheadings are used when appropriate. The main topical headings are I. Minutes of Meetings; II. Elections, Awards, Membership, and Human Resources; III. Ethics; IV. Board of Directors; V. Divisions and State and Provincial Associations; VI. Organization of the APA; VII. Publications and Communications; VIII. Convention Affairs; IX. Educational Affairs; X. Professional Affairs; XI. Scientific Affairs; XII. Public Interest; XIII. Ethnic Minority Affairs; XIV. International Affairs; XV. Central Office; and XVI. Financial Affairs. Changes to the language of the American Psychological Association (APA) Bylaws, Association Rules, or motions of the items are noted as follows throughout these proceedings: Bracketed material is to be deleted; underlined material is to be added.

In September 1967, the Council of Representatives voted that beginning in 1968, it would meet for only one day midway during the Annual Convention to act on essential routine business and to receive the agenda for its major meeting, to be set for a minimum of two days at a date apart from the Annual Convention. In accordance with that vote, the Council met in Honolulu, Hawaii, on September 5, 1972, at the Annual Convention, and in Washington, D.C., on December 2 and 3, 1972. The roll of representatives was called at both meetings, and more than a quorum answered to their names. These minutes constitute the official record of actions of the Association taken during the year. Reference is made to various reports, some of which will be published elsewhere. Copies of these reports were distributed to Council members and are on file in the Central Office. Extra copies of many of them are available from the Central Office as long as the supply lasts. The Board of Directors met six times during the year. All substantive actions of the Board taken during the year were reported to Council and are included in these minutes. Further details of the Board's actions are to be found in the minutes of each meeting. As in previous years, these minutes are organized in topical rather than chronological order.

Behavioral, neuropsychological, and brain imaging research points to a dedicated system for processing number that is shared across development and across species. This foundational Approximate Number System (ANS) operates over multiple modalities, forming representations of the number of objects, sounds, or events in a scene. This system is imprecise and hence differs from exact counting. Evidence suggests that the resolution of the ANS, as specified by a Weber fraction, increases with age such that adults can discriminate numerosities that infants cannot. However, the Weber fraction has yet to be determined for participants of any age between 9 months and adulthood, leaving its developmental trajectory unclear. Here we identify the Weber fraction of the ANS in 3-, 4-, 5-, and 6-year-old children and in adults. We show that the resolution of this system continues to increase throughout childhood, with adultlike levels of acuity attained surprisingly late in development.
