首先

In this study, we firstly demonstrated that BAMBI can promote Wnt signaling by reporter assays.

在本研究中，我们首先用报告基因分析的方法证明BAMBI能促进Wnt信号。

First of all, the are made of wood or bamboo.

首先，它们是木材或竹子做的。

This thesis consists of two parts. The first one was that boundary value problem was discrete with five point difference method. Three kinds of memory formats were studied, which were full matrix, half band width and row compress sparse. Full matrix memory format and half band width memory format first was contrasted. The results show that half band width has efficiency in space. Then the algebraic system of finite element method was solved by Gauss-Seidel iteration method to popular row compress sparse memory format.

本论文由两部分组成，第1部分针对边值问题，用5点差分格式进行离散，并对离散矩阵这类大型稀疏矩阵，研究了系数矩阵的3种存储格式的优劣，即：满矩阵存储格式、半带宽存储格式和按行压缩稀疏存储格式，首先我们将满矩阵存储方式和半带宽存储格式进行了对比，迭代法的数值实验表明：利用半带宽存储的矩阵在空间运算方面具有高效性；然后针对目前数值实验中流行的按行压缩稀疏存储格式，实现了有限元离散代数系统的迭代法的求解。

First, I started with a sheet of Celtec material and cut the curvature for the bulwark using a band saw.

首先，我开始与资产负债表celtec材料和削减曲率为堡垒，用带锯。

To begin with, I will tell you how to increase your bandwidth speed by 20%.

首先，我会告诉你如何提高您的带宽速度由20 ％。

The first is that I have no idea how much bandwidth I actually use on a regular basis.

首先，我不知道在正常情况下我到底用了多少的流量。

In the first chapter, using fragments of COI gene, we studied the phylogenetic relationships among species of five familes of Acridoidea with MP and Bayesian methods. The results were as follows:(1) Species of Acrididae, Gomphoceridae and all the Arcypterinae species of Arcypteridae are monophyletic. Species of Oedipodidae are supported as a monophyleticgroup, Ceracrinae species of Arcypteridae cluter together to make a monophyletic group. Epistaurus aberrans and Xenocatantops humilis is a phylogenetic group, Stenocatantops splendens and Hieroglyphus banian is also a phylogenetic group.

我们首先利用COI基因序列片段，使用最大简约法、贝叶斯法研究了斑腿蝗科、剑角蝗科、斑翅蝗科、网翅蝗科和槌角蝗科5个科42种的系统发育关系，得到如下结果：（1）由所有网翅蝗亚科的物种与剑角蝗科绿洲蝗亚科和槌角蝗科的物种组成一个单系群；斑翅蝗科的物种组成一个单系群；网翅蝗科的竹蝗亚科的黄脊雷蓖蝗和青脊竹蝗聚在一起形成单系群；斑腿蝗科的长翅十字蝗和大斑外斑腿蝗亲缘关系较近，形成一个单系群；长角直斑腿蝗和等歧蔗蝗始终聚在一起，形成一个单系群。

For example, we have two accounts at a bank I'll call First Denver National.

举例来说，我们有两个帐户，在银行，我会首先请丹佛的国家。

First, if you have already received a letter from the bank about foreclosure you should call the bank.

首先，如果你已经收到了一封来自银行约赎你应致电银行。

First, you get a monthly check from the bank that you can spend anyway you want.

首先，你得按月向银行查看，反正你可以用你想。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
