抓财务管理促工程建设--三峡一期工程财务管理回顾

财务管理是现代化企业管理的重要组成部分，也是三峡工程管理的重要内容。三峡工程在财务管理上提出了“两个适应”、“三个转变”、“四个树立”的指导思想和理顺财务关系，为搞好财务管理奠定了基础。三峡工程筹集资金是财务部门的首要任务，通过三峡建设基金（增收电费）、落实国家开发银行贷款、发行企业债券和利用外汇储备贷款，形成了以三峡建设基金和国家开发银行贷款为主渠道的资金来源。在财务管理中规范管理行为、提高人员素质、加强电算化管理和会计监督工作是十分重要的。

The role of human leukocyte antigen in susceptibility and clinical manifestations of sarcoidosis

To investigate the association of human leukocyte antigen (HLA) with susceptibility and clinical manifestations of sarcoidosis. Fifty-five patients with sarcoidosis were studied by using allele group specific polymerase chain reaction technique (PCR). Our data show that: (1) the gene frequency of HLA-DR5 is significantly increased in patients with sarcoidosis, but that of HLA-DR7 decreased. (2) Gene frequencies of HLA-DR9 and HLA-DR5 are relatively increased in male patients and in patients with stage I and stage IIa, respectively. The results suggest that HLA-DR gene might contribute to the susceptibility as well as to the difference of clinical manifestations in sarcoidosis.

Synthesis, characteristics and oxygen-sensitive properties of SrMgxTi 1 − xO3 nanocrystals

SrMg_xTi_{1 - x}O₃ nanocrystals (x = 0.1–0.6) were synthesized by the stearic acid gel method. Powder samples were characterized by X-ray diffraction and X-ray photoelectron (XP) spectroscopy. The results showed that the lattice parameter a and the O 1s XP spectrum changed not only with the Mg content x but also with the grain size d of the samples. The conductivity of a thick film specimen fabricated on an aluminium oxide wafer was investigated in a nitrogen—oxygen atmosphere.     

Improved method for HgI2 crystal growth and detector fabrication

Instead of the temperature oscillation method (TOM), a modified vapor growth method was applied in this paper to grow large HgI₂ crystals with fewer lattice defects by providing a relatively stable temperature field during growth. And a new processing technique of HgI₂ crystals was developed for detector fabrication by merging solution string-sawing and hand-cleaving. The lattice deformations caused during cleaving were reduced greatly by eliminating passivated layers on the sawed crystal platelets before cleaving.

CZF90测井中子发生器使用寿命浅谈

Ｃ／Ｏ测井中采用同步测量技术来分析非弹性γ与俘获γ，但在一些ＭＳＩ Ｃ／Ｏ测井中发现非弹性γ的一小部分或一大部分超前于非弹性门而进入俘获门，我们把这一问题叫做“错位”。“错位”使得Ｃ／Ｏ的ＣＩ值不正常，测井曲线不合格。这样的仪器不能用来测井。吉林油田测井公司碳氧比维修班成功地解决了Ｃ／Ｏ仪器“错位”等技术难题，在该油田所使用的ＣＺＦ９０－９４－０９发生器已测井８８口，累计打靶时间２３０ｈ，并且至今
