Many of the issues, which arise in teaching practice, are closely related with the imperfect teachers' qualities. The universal problems of primary-school teachers are the deficiencies of advanced educational theoretical knowledge and scientific research ability, the outdated knowledge structure, the inadaptation to the need of quality-oriented education, the low ability level of computer , English and employing modern educational technique, the lack of comprehensive ability, especially comprehensive liberal arts and comprehensive science, and the great difficulty in establishing selective courses and activity courses.

毋庸质疑，我国的师范教育还比较落后，小学基础教育师资的整体水平还不高，教育实践中出现了各种问题，例如：有些教师缺乏先进的教育理论知识；知识结构老化；不适应素质教育需要；计算机、外语能力差；运用现代教育技术手段的能力差；综合能力欠缺，特别是综合文科、综合理科的能力欠缺；等等。

In the second part of our research, YC-1, an indazole derivative, displayed impressive selective toxicity against the human lung squamous carcinoma cell line NCI-H226 and human kidney tumor cell lines RXF-631L by a panel of 39 human cancer cell lines (JFCR39) screening. Therefore, the molecular mechanism by which YC-1 affects NCI-H226 cell growth was studied.

在本论文的第二部份中，吲唑类化合物YC-1经利用日本JFCR39癌细胞株之抗癌活性筛选后发现，YC-1对於人类肺鳞状上皮细胞癌细胞NCI-H226以及人类肾癌细胞RXF-631L具有高度的抑制选择性，於是我们选择NCI-H226细胞株做为YC-1对抗肺癌之抗癌机制探讨模式细胞。

结果 根据儿童缺血缺氧性脑病后遗症的MRI影像特点，将其分为：(1)脑白质损伤为主：47例；①脑室周围脑白质脱髓鞘、软化：23例；②基底节豆状核、视丘神经元选择性损害：9例；③胼胝体受损变薄：15例；(2)脑灰质损害为主：18例；(3)局部或多处脑软化：9例；(4)广泛脑损害：5例。

The radio channel is time-variant, frequency-selective and noisy, so the received OFDM signals are corrupted by intercarrier interference.

但是由于无线信道的多径性和时变性，造成了接收端 OFDM 符号子载波间的干扰，为了能够准确地解调 OFDM 信号，就必须对接收到的信号进行信道估计。

Methods selective and limited minimally invasive debridement under arthroscope was applied to 54 patients with osteoarthritis of knee joint; hyperplasia of inflammatory synovial membrane and abrasion of anterior cruciate ligament were chipped or vaporized with radiofrequency, the corpus liberum were taken out, cartilage was scoured into certain shape; excision or partial excision were performed to hyperplastic intercondyloid spine, osteophyma and menisci; intercondyloid fossa was formed.results 45 cases were followed up for an average of 18 months (from 6 months to 24 months); the clinical symptoms of most cases released obviously and the joint function improved.conclusions minimally invasive debridement under arthroscope can effectively release oa symptoms, improve joint function and raise the quality of life.

对54例膝关节骨性关节炎患者进行关节镜下选择性、有限化微创清理术。手术内容包括刨削或射频汽化增生的炎性滑膜组织和前交叉韧带磨损、游离体取出、软骨打磨成形、增生髁间棘切除、部分骨赘切除、半月板部分切除、髁间窝成形。结果随诊45例，平均18个月（6～24月），大多数患者临床症状明显缓解，关节功能改善。结论关节镜微创清理术可有效缓解oa症状，改善关节功能，提高生活质量。骨关节炎；膝关节；关节镜检查
