考察黑龙江省高职院校学前教育专业毕业生在幼儿园幼教岗位上的适应现状,为高职院校学前教育专业人才培养与岗位对接提供依据。以《幼儿园教师专业标准（试行）》为视野,采用＂学前教育专业人才培养与岗位对接问卷＂,对东北、河北省等地16所幼儿园的园长及大三顶岗实习的学前教育专业毕业生共计76人进行调查,结果表明：无论从园长视野还是学生视野,高职院校学前教育专业的大三顶岗实习学生在对职业的理解与认识,一日生活的组织与保育,教学的激励与评价,教学反思与职业发展以及沟通与合作维度上得分较低;在对待幼儿的态度与行为、个人修养、幼儿发展知识、通识性知识、环境的创设与利用、游戏活动的支持与引导、教育活动的计划与实施维度上得分较高。园长和学生对幼儿教师岗位对接的认识上没有显著差异。

运用1999—2017年影响海林市农民收入增长的相关数据,通过主成分分析法,在原始数据的基础上整理计算并选取出13个影响农民收入的主要因素并分析它们对农民增收的贡献率。分析表明,城乡收入差距是影响农民收入增加的最主要的因素之一,以城带乡,逐渐缩小城乡发展差距是促进农民增收的主要思路。

果子狸对颗粒饲料的适应性研究

特产研究 2020年第1期42卷 21-24,28页

为了探究颗粒饲料对果子狸的适口性及体重的影响,试验选取10月龄体重基本一致的健康果子狸32只(雄性12只、雌性20只),按照雄雌比3∶5随机分成2组,试验组饲喂颗粒饲料,对照组饲喂常规粥状饲料。预试验7 d,观察果子狸采食颗粒饲料的行为... 详细信息

为了探究颗粒饲料对果子狸的适口性及体重的影响,试验选取10月龄体重基本一致的健康果子狸32只(雄性12只、雌性20只),按照雄雌比3∶5随机分成2组,试验组饲喂颗粒饲料,对照组饲喂常规粥状饲料。预试验7 d,观察果子狸采食颗粒饲料的行为变化。正式试验80 d,其中0~20 d、20~50 d、50~80 d果子狸的采食量分别为110、140和180 g/(只·d),测定各个时期果子狸的体重变化。结果表明,果子狸在第1天便全部采食颗粒饲料,没有出现拒食、腹泻、痢疾等情况;0~50 d,试验组和对照组内雄性、雌性果子狸的平均体重均有所下降(P>0.05),可能与配种期果子狸的采食量变少,活动增加有关,而50~80 d各组均增加了饲料投喂量,雄性和雌性果子狸的平均体重均有所增加,说明其采食量恢复正常。试验期内2组果子狸的平均体重变化趋势一致,无显著差异(P>0.05)。可见,果子狸对颗粒饲料的适应性良好,未来颗粒料可在果子狸的养殖中广泛应用。

以发放问卷和进行访谈的形式对海林市猴头菇种植农户的收益情况进行调研,结合猴头菇生产资料的投入情况对收益进行综合分析。运用OLS模型对调查数据进行回归,得出种植户当期投入、经营规模、家庭劳动力数量、户主受教育年限、种植历史、产品质量、是否加入合作社、是否网络营销、菌渣是否回收对种植户收入有正的影响;户主年龄对种植户收入有负的影响。在此基础上并结合新形势下的国家政策,对提高海林市猴头菇种植户的收益提出了相关的政策建议。

Research on two-dimensional(2D) materials has been explosively increasing in last seventeen years in varying subjects including condensed matter physics, electronic engineering, materials science, and chemistry since the mechanical exfoliation of graphene in 2004. Starting from graphene, 2D materials now have become a big family with numerous members and diverse categories. The unique structural features and physicochemical properties of 2D materials make them one class of the most appealing candidates for a wide range of potential applications. In particular, we have seen some major breakthroughs made in the field of 2D materials in last five years not only in developing novel synthetic methods and exploring new structures/properties but also in identifying innovative applications and pushing forward commercialisation. In this review, we provide a critical summary on the recent progress made in the field of 2D materials with a particular focus on last five years. After a brief backgroundintroduction, we first discuss the major synthetic methods for 2D materials, including the mechanical exfoliation, liquid exfoliation, vapor phase deposition, and wet-chemical synthesis as well as phase engineering of 2D materials belonging to the field of phase engineering of nanomaterials(PEN). We then introduce the superconducting/optical/magnetic properties and chirality of 2D materials along with newly emerging magic angle 2D superlattices. Following that, the promising applications of 2D materials in electronics, optoelectronics, catalysis, energy storage, solar cells, biomedicine, sensors, environments, etc. are described sequentially. Thereafter, we present the theoretic calculations and simulations of 2D materials. Finally, after concluding the current progress, we provide some personal discussions on the existing challenges and future outlooks in this rapidly developing field.
