位置正常

Working under the vibration-centrifuge compound environment, the components of the vibrator are unbalanced because of the centrifugal force, which prevents the vibrator from working properly.

The result of uroscopy of the proband was strong positive. There was a novel deletion mutation of c.876-877 del TC in the coding region of exon 6 of IDS gene, which was a hemizygous mutation. However, the mutation of his mother and sister was a heterozygous mutation. Detection of the exon 6 of IDS gene showed that the mutation was not found among normal controls and other patients with MPS I, IV, and VI other than MPS II. Homology comparison of amino acid sequences from different species showed that the phenylalanine glutamine of the mutation site of c.876-877 del TC located in p.292-293 was highly conserved. The activity of IDS enzyme of the proband was only 2.3 nmol/4 h/mL, which was much lower than normal; but the activity of IDS enzyme of his father, mother and sister was 641.9 nmol/4 h/mL, 95.8 nmol/4h/mL and 103.2 nmol/4h/mL, respectively.

结果显示：先证者尿检呈强阳性；其IDS基因exon 6编码区内存在c.876-877 del TC新缺失突变，为半合子突变，而其母、其姐为杂合突变；正常对照和其他非II型MPS患者的IDS基因exon 6的检测结果均未发现该突变；不同物种氨基酸序列的同源性比对显示： c.876-877 del TC突变所在的位置即p.292-293的苯丙氨酸谷氨酰胺高度保守；酶活性测定的结果显示：先证者的IDS酶活性仅为2.3 nmol/4 h/mL，大大低于正常值，而其父的为641.9 nmol/4 h/mL，其母的血浆酶活性为95.8 nmol/ 4h/mL，其姐的为103.2 nmol/4 h/mL。

Sewerage pump pool must be installed at lower place,designed for discharging the castoff that producted by men in time.all the live draining water from the basement,such as basin,commode,washer machine,fabric pool,shower bath and bathtub so on contact with the sewerage pump pool ,and than drain into sewage well outside by passing through the watershoot,the pump pool should not have water ,or it will drunk the pump machine bad,make which can not operate normally.

对我来说有点难，请高人帮忙看看如何翻！急！污水泵池是为了及时排出生活中所产生的废弃物而设计的，必须安装在较低的位置。地下室所有的生活排水，如：面盆、恭桶、洗衣机、墩布池、淋浴间、浴缸等设施的排水都要经过排水管道与污水泵相连接，再通过排水管道直接排至室外污水井，泵池内不应有水，否则会泡坏污水泵电机，导致电机不能正常运行。

飞机正在下降，请您回原位坐好，系好安全带，收起小桌板，将座椅靠背调整到正常位置。

Alpha-1 antitrypsin is the most abundant circulating protease inhibitor in the body, Dr. Lomas said. Its most common deficiency mutation is the Z allele, where the amino acid lysine is exchanged for glutamic acid at position 342 in the polypeptide chain (Glu342Lys). About 1 in 1700 whites of northern European descent are homozygotes for this mutation and thus have plasma antitrypsin levels that are 10% to 15% below normal, he said.

Lomas博士表示，甲一型抗胰蛋白酵素是身体内最充分的循环蛋白酶抑制剂，最常见的缺损突变在Z对偶基因，该处的胺基酸 lysine与麸氨酸在多胜肽链的第342位置交换(Glu342Lys)；北欧血统白人每1，700人有1人是此一突变的同合子，因此血浆抗胰蛋白酵素值比正常低10%到15%。

If a user operates an operation panel to input an instruction for normal playback, then a control circuit of a digital television monitor determines a frame to be played back at present as a noticed frame and requests the hard disk recorder for image data of successive 15 frames forwardly and backwardly adjacent the noticed frame and image data at positions of time intervals of 0.5 seconds within a range of 2 minutes forwardly and backwardly of the noticed frame through an IEEE 1394 cable.

如果用户操作操作面板输入正常播放指令，那么数字电视监视器的控制电路确定当前播放的一帧作为标记帧，并且通过IEEE1394电缆向硬盘记录器请求标记帧的向前和向后连续的15帧的图像数据以及标记帧向前和向后2分钟范围内在0.5秒时隙内的位置的图像数据。

At first the combined defect was transformed into cavitary defect with metal mesh, then the contained acetabulum was tightly packed with deep-frozen morselized cancellous allograft chips (size 7~10mm), the anatomy of the hip was reconstructed and the cup was inserted after pressurizing the cement directly onto the graft.

结果表明：正常人上、中面部骨骼存在对称性的正常变异，其范围在 1 3— 1 8岁保持稳定，水平向小于 8%，垂直向不超过 9mm；在其相对于颅底的位置关系及其骨骼各对应部位之间，有较好对称性；面部骨骼的生长发育具有潜在的优势特点。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
