During 1997, it continued to m a n a ge the New Horizons Vietn a mese Refugee Dep a rture Centre (for Vietn a mese refugees a ccepted for resettlement overse a s). The C A S deployed 40 members a nd eight perm a nent st a ff to m a n a ge the centre on a d a ily basis .

在一九九七年，民安队继续调派队内40名队员和8名常额职员合力管理新秀越南难民离港中心的日常事务(该中心专供容纳已获外国收容的越南难民)。

In mesothermal area where accumulated temperature is 2400～2850℃, the range of increasing production is the biggest, income increase is approximately 1700～2000y/hm2, which is the major region to popularize the technique. The range of increasing production is bigger in north of Heilongjiang Province where accumulated temperature is under 2200℃, it is comparatively suitable for popularizing the technique. Most areas of Liaoning Province where accumulated temperature is over 3000℃, the effect of production increase is not noticeable, and the technique is unsuitable.

在日平均气温≥10℃积温2400～2850℃的中温地带，即吉林省东部、黑龙江省东部和中北部，地膜增产增收幅度最大，增收额达1700～2000元/hm2左右，是主要推广区域；积温低于2200℃的黑龙江省北部地区增产幅度较大，也比较适合推广地膜覆盖；积温高于3000℃的辽宁省大部，增产增收很不明显，不宜推广该项技术。

Of the 19 cases,19 fetus were found,MRI confirmed 14 cases considered or suspected as fetal corpus callosum agenesis by US(8 cases are completed agenesis of corpus collosom-CACC,6 cases are partial agenesis of corpus collosom-PACC, and 5 cases had took on autopsy),however 3 cases are mild enlargement of lateral cerebral ventricle and 2 cases are leukodystrophy.In these cases,MRI confirmed a Dandy-Walker syndrome and a lipoma of corpus callosum suspected by US,detect a Dandy-Walker syndrome and a microcephalus made missed diagnoses by US.The fetal corpus callosum and additional cerebral anomalies were shown more clearly on MR T_2-weighted images.

胎儿胼胝体长度与额枕径的比值在24～36孕龄阶段相对较恒定。2、19例孕妇共检出胎儿19个，MRI证实超声疑诊的胎儿胼胝体发育不全14例(完全型胼胝体发育不全8例，部分型胼胝体发育不全6例，有胎儿尸检结果对照者5例)，3例为单纯侧脑室轻度扩张，2例考虑脑白质发育不良，合并Dandy—Walker综合征1例，胼胝体脂肪瘤1例，检出超声漏诊合并Dandy-Walker综合征1例及脑小畸形1例。

Photochemical reduction of UO2(NO3)2 and production of HNO2 in 30% TBP-kerosene solution are investigated using an argon ion laser with 488 nm monochromic beam, and the effects of some, factors on quantum yield have also been studied.

用Ar~+激光器的488nm单色光研究了UO_2(NO_3)_2-30％TBP-煤油体系中U的光化学行为。实验表明：光照后TBP有机相内含有还原生成的U和TBP的主要降解产物DBP和丁醛；生成U的量子产额与酸度、温度、TBP浓度有关。

Cyphotilapia frontosa is a monomorphic species with little or no difference between males and females.

雄性额部有一个隆起，不过这个特征并不是绝对可以保证区分的。

CT scan showed left frontal sinus mucocele that extended to the left orbit.

CT报告左额窦粘液囊肿蔓延至左眶内。

A mucocele is a ball of concentrated mucus surrounded by a layer of pseudo-stratified columnar epithelium. It gradually grows and slowly expands in a paranasal sinus cavity, and even erodes the adjacent structures. Most paranasal sinus mucoceles occur in the frontal and ethmoid sinues. Mucoceles are usually unilateral, and are rarely bilateral (4%).

鼻窦黏液囊肿是鼻窦黏液被伪复层柱状上皮(pseudostratified columnar epithelium)所局限，在鼻窦内逐渐成长与扩张，甚至侵犯到邻近的结构，好发於额窦及筛窦，且多为单侧病灶，双侧较为少见(4%)。

Methods 6 cases (6 eyes) with Marcus-Gunn jaw-winking syndrome were received surgical treatment of levator myectomy and combined frontal-is muscle suspension.

Marcus Gunn张口瞬目综合征6例（6眼）采用上睑提肌水化分离及节段切除联合额肌瓣悬吊术。

The myelinization of cerebellar white matter,middle cerebellar peduncles,anterior limb of internal capsule,splenium and genu of corpus callosum,centrum semiovale,the white matter in parietal-occipital area and frontal-temporal area were documented at birth to 5,2～4,3～7,3～5,4～7,2～7,3～9 and 4～12 months old,respectively.

髓鞘形成至成熟时间：小脑上下脚、桥脑背侧、丘脑腹外侧和内囊后肢后部出生时已成熟，小脑自出生至5个月，小脑中脚2～4个月，内囊前肢3～7个月，胼胝体后部、膝部分别是3～5个月、4～7个月，半卵圆中心2～7个月，枕顶叶白质3～9个月，额颞叶白质4～12个月。

They are also widest at the nasofrontal suture, narrowest at the nasofrontal angle, and tend to widen again inferior to the radix before narrowing near their inferior margin.

最宽部分在鼻额相接处，鼻额角处最窄，从鼻根重新变宽，至接近下缘处再次变窄。

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.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
