  1. Heamagglutination tests were applied to detect virus in allantoic fluid of chicken embryos which were infected by b95 gathered from the vaccinated chickens " cloacal and oral cavity. the results show that the virus may be detected from 2 days to 11 days after the chicken being vaccinated. the hi antibodies were measured by heamagglutination inhibition tests. there is no significant difference between the immunized and the control chickens which were fed in one case. chickens were immunized with b95 by different immunization meathods or with different vaccines by the same meathod. lt is demonstrated that eyedrop, drinking water, spray or muscle injection all can stimulate good effects, but eyedrop and spray seem to be the best meathods. b95 immunized chicken have relatively higher hi titers and it also can last for a longer time than others

    但如果兩者相隔10天以上免疫， b95免疫不受h120的影響；如果同時免疫b95和h120 ，加大b95的免疫劑量也能獲得良好的免疫效果。用棉拭子采b95免疫雞口腔、泄殖腔的分泌液，檢測其中病毒的存在，結果免疫后2 11天雞口腔和泄殖腔中均有病毒的存在，說明b95免疫雞帶毒時間長。研究結果表明， b95具有不受母源抗體干擾、 hi抗體產生快、水平高、持續時間長、同居擴散性強等特點，因此b95是一株優良的、具開發前景的新的新城疫疫苗株。

    心理契約的變革要求我們對人力資源管理系統中某些與心理契約關系密切，同時隨著員工心理契約的變化難以有效發揮作用的部分進行變革，具體可以從以下幾個方面入手：建立心理契約動態追蹤測量制度以及時了解員工心理契約的變化特點；建立薪酬模式動態選擇機制以滿足員工對經濟利益的需求；進行職業生涯設計以滿足員工自我實現的需求；建立雙重公平體制以滿足員工對公平的追求；實行自我管理式學習以滿足員工對能力提高的需求；對員工進行心性開發以引導員工形成正確的心理契約。只有組織的管理者真正認識到心理契約的重要性，認識到心理契約對員工的態度和行為的影響，重視心理契約的建立和維護，才能在人力資源管理甚至整個組織管理中應用好心理契約這一劑良方。
