This paper designed a PMLSM with long primary winding and short secondary winding used in the electromagnetic launch system, whose primary winding was divided into two sections.

设计了用于电磁弹射的长初级短次级PMLSM，初级绕组采用分段结构，减小了绕组漏电感，降低了系统无功功率。

According to performance degree of the positive symptom as the below: compulsion, physical symptom, human sensibility, antagonism, depression, bigot, anxiety, terror, and psychoneurosis; the mental health state of the primary school teachers is better than the middle school teachers; the senior middle school teachers have the worst mental health state; the mental health level of male teachers are equal to the female teachers; the mental health level of the teachers in charge of classes are equal to the teachers not in charge of classes, there is not notable difference; the teachers mental health level in each age-phase almost the same; the factors of the primary and middle school teachers divorced are higher than the single teachers and the teachers married, there is not notable difference.

本研究采用SCL-90临床症状自评量表，对258名中小学教师进行测试，探讨中小学教师心理健康的状况，结果表明：中小学教师的心理健康水平低于全国普通人群，心理健康问题的检出率为15.9%，按其阳性症状的表现程度依次为：强迫、躯体化、人际敏感、敌对、抑郁、偏执、焦虑、恐怖、精神病性；小学教师的心理健康状况比中学教师好，高中教师的心理健康状况最差；男女教师心理健康水平在总体上基本相当；班主任和非班主任的心理健康水平基本相当，没有显著差异；各年龄阶段的教师心理健康水平基本相当；离婚的中小学教师各因子分略高于未婚和结过婚的教师，但差异不显著。

This suggests that the model is not very sensitive to the changes of primary force and primary length of individual horizontal rectus.

结果表明，上述两个指标变化在10％范围内时，手术矫正量的变化小于1.2％，水平直肌的初张力变化在30％范围内时，手术矫正量变化小于4％，说明本文提出的模型对个体肌张力的差异和个体眼外肌解剖长度的差异不是很敏感。

The slight redissolution and then coarseness of primary Si phase at higher annealing temperature had been found,but the coarsening ratio of primary Si phase was lower than that of β-Al4FeSi.

退火温度低于310℃时，δ-Al4FeSi2相未明显粗化；当退火温度高于310℃时，亚稳相δ-Al4FeSi2转变成稳定相β-Al5FeSi，β-Al5FeSi相随退火温度的提高而明显粗化。

Based on our experiences, we conclude that: 1 rhabdomyoma is the most common primary cardiac tumor in children; 2 most pediatric tumors are associated with tuberous sclerosis; 3 clinical presentation is determined by the tumor size and number of tumors, and whether expansion of the malignancy has resulted in cardiac blood-flow obstruction; 4 there is a strong possibility of regression of the primary cardiac tumor, with surgery recommended only when cardiac symptoms are severe; and, 5 unless there is a significant obstruction of blood flow, chemotherapy is still the treatment of choice for secondary cardiac tumors.

根据我们的经验，我们认为(1)横纹肌瘤是儿童最常见的心臓肿瘤，(2)临床表现的严重度取决於肿瘤的大小，数目以及是否占满了心臓腔室而有血流阻塞的现象，(4)在原发性肿瘤中是有机会自发性的变小，而且除非有严重的心臓症状，否则并不建议开刀，(5)在次发性肿瘤中化学治疗仍然是治疗上的首选，除非有血流阻塞的现象。

In any case, if we do allow ourselves to assume that it is a microphysical truth that H2O is the satisfier of the of the primary intension of 'water,' why do we not have equal justification to assume that it might be a microphysical truth about the actual world that pyramidal cell activity is the satisfier of the primary intension of 'consciousness'?

在任一情况下，如果我们允许我们自己假设是微观物理真，那么为什么我们不在相同的辩护意义上假设'某某细胞活动就是满足『意识』的基础内涵的东西'是关于现实世界的微观物理真呢？
