A new method and the principle is presented for plotting the critical metacentric height curve which meets IMOs intact stability criteria and weather criteria,and the critical metacentric height curve which meets 1976 SOLAS intact stability criteria. And the critical metacentric height curve is used in the Stability check of bulk grain carriers in accordance with the stability rules for bulk grain carriers.

Methods The subjects were 2 550 children aged 17~20 years from five cities of China.The adult height of children was measured and the midparental height was determined by the height self-reported of childrens parent.

研究样本为达到成年身高的2 550名（男1 189名，女1 361名）中国广州市、上海市、温州市、大连市、石家庄市五城市的正常儿童。

For nearly fifty years, concept of normal height has been adopted in China. However, thanks to the rapid development in geodesy and other computation technology, the HASL can be computed as accurately as the normal height. Particularly, the HASL is very fit to the case of wide and high multimountain areas of China. This ideal of orthometric height would be accepted by many people.

尽管近50年来我国仍采用正常高系统，但随着时代的发展、研究的深入，如今推求正高的精度又与正常高的非常接近，况且它又符合我国幅员广大的高海拔山区的实际情况，因此用正高代替正常高的观念将会被人们所接受。

The normal height and orthometric height of the snow surface of the QF summit are 8846.67 m and 8847.93 m respectively. The orthometric height of rock surface of the QF summit is 8844.43 m, and the thickness of the snow-ice layer on the summit of the QF is 3.50 m.

由此测得珠峰峰顶雪面正常高为8846.67m，珠峰峰顶雪面正高为8847.93m，珠峰峰顶岩面正高为8844.43m，珠峰峰顶相应点的冰雪层厚度为3.50m。

This study thoroughly inspects reciprocal method and leap-frog method of EDM trigonometric leveling along with relationship between EDM height, ellipsoid height, and orthometric height. An experimental area with 200m, 400m and 600m span intervals were set up with vertical angle error ±1.5〞and EDM error ±（2mm+2×10-6×Smm）.

本研究规划实验区实地针对200m、400m、600m三种测段长，采用之全测站仪之垂直角中误差为±1.5〞，测距中误差为±（2mm+2×10-6×Smm），进行EDM三角高程测量，并对测量方法及观测成果精度进行分析，实际探讨短距离EDM三角高程代替水准测量的可能性。

They also noted that a radiograph of the hand is useful for determiningwhether the digital phalangeal epiphyses are capped (post-peak height elocity) or uncapped (pre-peak height elocity) because capping strongly correlates with the timing of peak height elocity, an important parameter to study when predicting cure progression.Dimeglio et al.

还发现手部平片在确认手指近端骨骺扩张或未扩张方面有用处，因为骨骺扩张与峰值出现时间相关性很强，是预测曲线回归的重要参数。

Results The prevertebral height recovery platform stage happened in all the three methods of reduction. There is no significant difference between the prevertebral heights in the maximum experimental load; the prevertebral height increased first and stayed stationary later in the hyperextension reduction procedure; in the device reduction process, the prevertebral height stayed stationary at first and dereased later.

结果 在三种复位过程中都存在椎前高度恢复平台期；在试验载荷最大值时椎前高度前后比较，差异均无显著性意义（P＞0.05）；过伸复位中椎前高度是先增加后停滞，器械复位中椎前高度是先停滞后增加。

The diffracting optical element includes two layers equal in the height of the relief pattern and opposite to each other in the direction in which the height of the relief pattern varies in a period, and another layer differing in the height of the relief pattern from the two layers.

衍射光学元件包括在凹凸模式的高度上相等并在凹凸模式的高度在一个周期内变化的方向上彼此相反的两层，以及凹凸模式的高度不同于所述两层的另一层。

Height and Weight The American Pit Bull Terrier must be both powerful and agile so actual weight and height are less important than the correct proportion of weight to height.

高度和体重美国比特牛头更必须既强壮又灵活，因此体重和身高的恰当比例要比实际的体重和身高重要。

" I' d like to get some rough idea about music in the baroque ear, please."

请简要介绍一下巴罗克时期的音乐，好吗？

The results showed that the peak latency and pattern of SEPs elicited by electrical needling in LI-l1 and MP were similar. The amplitude of SEPs elicited by electrical needling in LI-l1 was higher than that of MP. There was no obvious SEPs generation when MM was electrical needling.

结果显示，电针刺激曲池穴和其邻近桡侧伸腕长肌运动点诱发性脑电波的波形和波峰时间是类似的，只是穴位的诱发性脑电波波幅较大，而电针刺激非穴位点并没有明显的诱发性脑电位。
