This method uses K-L transform to produce matrix of sample aggregate, get a low dimension sub space to describe the wrist bone's radiographs. Each image makes projection, and obtains one group of coordinate coefficients. The coefficients indicating the position of this image in sub space can be discerned the image feature.

该方法通过对由中指骨组成的训练样本集的产生矩阵做K-L变换，用一个低维子空间来描述中指骨X光图像，每幅图像向其作投影，并获得一组坐标系数，这组系数表明了该图像在降维子空间中的位置，能较好地表征该幅图像的特征信息。

Objective To find out an effective approach to treat fracture of metacarpal bone and phalanges,especially near the joint fracture.

目的 寻求掌指骨骨折，特别是关节附近掌指骨骨折更为简便、有效的牵引和固定方法。

Results Comminuted fracture of metacarpal bone and phalange is all heal up.

目的 探讨开放性、粉碎性掌指骨骨折的治疗新方法方法应用可吸收线内固定骨碎块重建掌、指骨。

The normal values of metacarpophalangeal length for Chinese children of five cities in China provide references for metacarpophalangeal pattern profile analysis in clinical genetics and endocrinology.

中国五城市儿童掌指骨长度值为遗传学和内分泌学临床应用掌指骨模式特征分析提供了参考。

Abstract］ Objective The normal values of metacarpophalangeal length were presented for Chinese children of five cities.Methods The sample was 3 259 normal Han Chinese children aged 2~19 years from five cities of China.

目的 对儿科临床应用掌指骨模式进行分析，提出中国五城市儿童手部掌指骨长度正常参考值。

Results In male group, the peak value of phalangeal BMD (MP2-4) of the nun-dominant hand occurred between the age of 20-39 years, then decreased the age of 40 years and there is still no dramatic to decline 79 years old.

结果 男性非优势手指中节指骨(MP 2~4)骨密度峰值在20~39岁组，40岁以后随年龄增长逐渐下降，至79岁无明显加速变化现象。女性非优势手指中节指骨(MP 2~4)骨密度峰值在20~39岁组，50岁以后明显下降。

Methods:Fifty-six patients with metacarpal and phalangeal fractures who were reviewed in the study were divided into two groups:Group A and Group B.Thirty-two patients in Group A were treated with open reduction,Kirschner internal fixation and postoperative plaster splint external fixation.Other 24 patients in Group B were treated with open reduction,Mini-plate internal fixation,without any external fixation.

回顾分析经完整随访的56例掌指骨骨折患者的治疗和康复情况，A组：32例掌指骨骨折患者予以行切开复位交叉克氏针内固定接骨术，术后石膏夹板外固定；B组：24例掌指骨骨折患者予以行切开复位微型接骨板内固定接骨术，术后未用外固定。

Results 17 patients reported in the literature had primary bronchogenic carcinoma with metastases of phalanges of fingers as its first symptom. 7 patients' metastatic lesions located in their phalanges of left hands, 9 right hands and 1 both hands. The distribution of the quantity of the phalangeal metastases between two hands was almost equal. 3 patients' metastatic lesions were situated in proximal phalanges of fingers, and the rest in distal. 6 patients' ill fingers had had trauma history.

结果 在文献报道的以单纯指骨转移为首发症状的17例原发性肺癌的病人中，其转移病灶位于左手指骨者7例，右手指骨者9例，双手指骨者1例，指骨转移病灶的数量在两手之间的分布大致相等，除3例病人其转移病灶位于近节指骨外，其余病人的转移病灶均位于其末节指骨；有6例病人的患病手指既往曾有外伤史。

Objective To find out an effective approach to treat fracture of metacarpal bone and phalanges,especially near the joint fracture.Methods Closed reduction by X-ray fluoroscopy and skeletal traction from distal part with self-designed bone tractor.

目的 寻求掌指骨骨折，特别是关节附近掌指骨骨折简便、有效的牵引和固定方法方法应用自行设计的外固定支架，在电视X-ray透视下复位，于骨折远端的指骨行骨牵引治疗，并随时调整牵引力。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.
