"We've been able to take very large fibroids (12-14 cm in diameter) out through these small incisions by first morsellating the fibroid with a scalpel before enucleating it," said Dr. Glasser, noting the advantage over laparoscopy, which is not recommended for fibroids greater than 7 cm in diameter."It's a little different approach, but it works very well and it's a hemostatic way of performing a myomectomy," he added.

Glasser医师表示，在清除步骤前，会先以解剖刀捣碎纤维瘤，如此一来，我们可以经由这些小切口来去除很大的纤维瘤(12到14公分的直径)；相较於腹腔镜手术法，这个方法具有较高的效益，因为腹腔镜手术法并不建议用在去除直径大於7公分的纤维瘤；这个方法有一点不同，但是效果很好，而且在进行肌瘤切除时，此法具有很好的止血性。

Isolates CNR-1 and CNR-2 were from Brassica napus; CNA-1and CRW-1 from Rhododendron simsii and Oxalis corymbosa respectively. All isolates grew well in R-2 liquid medium and exhibited contractive movements. The colonies of all isolates were circinal and grain-like in solid medium. Through electron microscopy, all isolates exhibited helicity during their growth phase. All isolates could pass through a 0.22 μm filtrate membrane and resist to penicillin (2000 U/mL). They must grow in medium with serum.

Science and technology of total bureau of national wide report manages concerned personage expresses, Direct seeding satellite and before the power with hookup satellite stronger than having photograph, receive in the ground before defend inspect an item, need a diameter to be in of 3-5 rice ' caldron ' receive facility with other ground, and inspect an item to passing what direct seeding satellite conveys to defend, televiewer can use a diameter to be in of 0.45-0.6 rice ' pannikin ' can receive directly.

国家广电总局科技司有关人士表示，"直播卫星与以往的转播卫星相比具有更强的功率，以往在地面接收卫视节目，都需要直径在3-5米的'大锅'和其它地面接收设备，而对于通过直播卫星传送的卫视节目，电视观众则可以使用直径在0.45-0.6米的'小锅'就可以直接接收。"

Based on the analysis of mechanism and spread characteristics of the vibration wave produced by small diameter abnormal hammer tamping,and with the example of the engineering of dynamic compaction on a rubble fill site,the velocity-distance equation is built and the minimum safety distance is defined during small diameter abnormal hammer tamping with the maximum resultant velocity as the evaluation index.

The experimental results show that the diameter and the distribution of composite nanofibres increase respectively with the increasing of the size of spinneret.

实验发现：随着喷头孔径的增大，得到的复合纳米纤维的直径和直径分布范围分别变大；随着电压的增加，复合纳米纤维的珠串结构减少，甚至消失。

Meanwhile, result comes out that seven fossil samples are mostly evergreen Araucarioxylon, deciduous species prapably exists, but their fixed numbers of growing year are extraordinarily variant; Analysis of ariance indicates that, imposing ray cells, radial tracheid diameters-, the ratios of ray cells to radial tracheid diameters on distinguishing seven samples is doable as a whole, while not fitting for individuals.

经方差分析可以看出，利用射线直径、管胞直径和射线管胞比可以在总体上区分各标本，但对个别样本不适用；射线高度这一性状在各标本间差别很小，不能区分；结果认为：标本2和标本6的性状最相近，为相同的种类；标本1、4、7可能为同一属；对方差和CSDM曲线的综合分析认为，标本1、3、6的生长年限存在一定的区别，可能导致在方差分析上出现些许误差。

His AERIAL LOCOMOTIVE, with a hydrogen-filled compartmented gas "spindle" 800 feet in length and 50 feet in diameter, was to carry between 50 and 100 people at a speed of 60 to 100 mph The great machine was to be remain aloft for 12 hours at a time, propelled by two steam engines driving two "fan wheels or propellers" each of which would be 20 feet in diameter and revolve at 200 rpm He estimated that the machine would weigh a total of some 14,000 pounds and would generate a total buoyant lift of 56,000 pounds, leaving 42,000 pounds for 200 passengers and luggage.
