However, the weedy rice has became an another special type for long time evolution and domestication, so its resistance is superexcellence than the cultivable rice, and also become a natural gene storeroom.

然而，经历漫长的自然进化和某种特定稻作环境的驯化，杂草稻已成为稻种资源的一个特殊类型，较野生稻而言，其特殊生物学性状和抗逆性等优良性状易于在育种中直接利用，是水稻品种改良的重要育种资源，同时也是稻种遗传进化研究的必备材料。杂草稻长期自然生长繁衍，其抗病、虫、寒、旱、盐碱等特性优于栽培稻，而且与栽培稻的亲缘关系相对接近，是一种改良栽培稻抗逆性的天然基因库。

［Objective］To explore the clinical efficiency,operative methods,apparatus assembly and postoperative administration of Ilizarov technique in the correction of talipes equinovarus.［Method］From January 2003 to May 2006,32 patients were corrected with QIN Si-he's orthotics devices on the Ilizarov principle of tension-stress,which involved 15 males and 17 females,the age ranged from 10 to 25 years.

［目的］探讨Ilizarov技术矫正马蹄内翻足畸形的手术方法及器械改良、术后管理方法的改进及疗效［方法］2003年1月～2006年5月，根据Ilizarov张力应力法则，应用秦泗河改良的外固定矫形器，遵循Ilizarov穿针固定的基本原则，共手术治疗马蹄内翻足32例，男15例，女17例；年龄10～25岁，平均17岁。

The underutilization of germplasm resources and empirical based approach by conventional breeding strategy are responsible for the slow progress of rice improvement in the past decades.

现有常规育种技术对种质资源的低利用率及其在性状改良上的局限性是近几十年来水稻改良出现徘徊局面的根本原因。

The first-generation prototype is modified after the original invention patent, some shortages have been found after testing and using the washstand.

第一代原型机由原发明的创意改良而制出，经试验使用后发觉仍有些缺点，而改良后的第二代的原型机已具备商品化的优势。

This paper introduced the study on insect resistance, disease resistance, weedicide resistance, stress tolerance, improving quality, improving development, increasing photosynthesis and efficiency of azotification in crop breeding, and expatiated methods and benefits of gene engineering in improving crop variety.

从抗虫、抗病、抗除草剂、抗逆以及品质改良、改善发育状况、提高光合作用和固氮效率等方面论述了基因工程在作物育种中的具体应用和进展，阐述了基因工程改良作物品种的方法和优点。

Chest excursion of 25 normal subjects at Louis' angle and xiphoid process were measured with traditional-tape and modified-tape by three physical therapists. The procedures and methods of measurements, either traditional-tape or modified-tape, were standardized.

由三位物理治疗师分别使用传统皮尺和改良皮尺，在鲁易士角和剑突两处，测量25位正常的受试者的胸腔活动度，测量的方法和程序，不论是使用传统皮尺或改良皮尺，都是一致的。

目的 评价改良心肌保护对婴儿法洛四联症期手术治疗的影响方法 1997年1月～2003年7月对56例婴儿法洛四联症病人行一期手术治疗，男39例，女17例，年龄3～12月，平均（9.36±2.80）月，体重3.511kg，平均（8.83±1.25）kg.36例采用传统心肌保护，20例采用改良心肌保护。

A ideal modifier formula was designed with various quality modifiers produced by the help of the modern international standard apparatus such as farinometer,extensometer,viscosimeter and rheometer.

借助现代国际标准仪器设备——粉质仪、拉伸仪、糊化粘度仪和流变仪，研究了多种品质改良剂，得到一个较理想的面条改良剂配方。
