The results indicate that female wasps deposit HMPs on the chorion of host eggs with her ovipositor near the end of egg-laying process. Na ye females do not posses the ability for recognizing the marking pheromones and have to obtain the ability though the learning process, in which the wasp inserts her ovipositor into a host egg to determine whether the egg has been parasitized followed by antennal drumming on the exterior. Once the learning process is completed, the female wasp will be able to discriminate between parasitized and unparasitized hosts and reject a parasitized egg by simply drumming on the exterior of the egg. Learning plays an important role in reducing initial rejection time when an unsuitable host is encountered. Female wasps of T. astriniae can quickly learn to associate the presence of a HMP on host egg chrion with the internal status of the egg.

研究结果表明，玉米螟赤眼蜂的寄主标记信息素是在其产卵过程中的收场阶段由产卵器产生的，并且标记在寄主卵表的化学物质；玉米螟赤眼蜂对标记信息素的识别不具有先天性，其必须先用产卵器插入寄生卵来检测是否被寄生，然后其触角不停地敲击，通过学习获得对标记信息素的识别能力，从而放弃了对寄生卵的选择，学习对初始放弃时间有着重要影响，改善了其对寄主搜索效率，这种学习行为是与寄主联系在一起学习的，它能根据寄主被寄生与否而对标记信息素作出反应与不反应。

Methods Total of 164 patients with first-episode schizophrenia were evaluated before treatment, at the end of 12 weeks treatment and then annually till 5 years on 10 cognitive function tests, including Weschler adult intelligence scale, Weschler memory scale, grooved pegboard test, finger tapping test, motor function test, hand coordination test, trail making test A and B, Wisconsin card sort test, and verbal fluency test, together with BPRS, SANS and GAF. Results The scores on all cognitive function tests were not significantly related to total scores of BPRS, SANS and GAF before treatment.

对164例首发精神分裂症患者进行随访观察，于治疗前、治疗12周末、治疗1年末、2年末、3年末、4年末、5年末各做1次韦氏成人智力量表、韦氏记忆量表、铁槽铁钉测验、手指敲击试验、动作功能测验、手功能协调测验、连线测验A和B、威斯康星卡片分类测验及言语流利性测验等10项神经心理测查及简明精神症状评定量表、阴性症状评定量表、功能总体评定量表评定。

But they have their own difficulties: the hammers that hit the strings have to be coaxed not to sound like perc ussion, and each overlapping tone has to sound clear.

但调音师们也有他们的难处：他们必须耐心地调理敲击琴弦的音锤，不能让音锤发出的声音像是打击乐器，而且每个交叠的音都必须要清晰。
